BDO Finland acquires Consilium Corporate Finance Oy
BDO USA announces impressive revenue growth for fiscal year 2014
25 May 2011
On 24 May the European Parliament's Legal Affairs Committee adopted its final report on the European Commission's Green Paper on the future of audit.Indicating the Parliament's support for major reform of the audit sector in response to the financial crisis, the Committee recommended the following key points:- Clauses in commercial contracts which restrict the choice of auditor should be outlawed
- A demand that public procurement should aim to use firms other than the Big Four and that public bodies should set a benchmark percentage for use of non Big Four firms- In connection with tendering by public interest entities, the Commission should stipulate that fair access to the tendering procedure is provided for audit firms alongside the Big Four, including at least two other firms
- Takeovers by the Big Four must be considered in the light of impact on growth of other firms or networks
- The European Commission should establish equal competitive conditions in the audit market, not least by making access to the market easier and removing obstacles for more firms. To help this, it should also explore ways that will allow the public sector, including the European Institutions, to better judge the quality of audit services provided by audit firms irrespective of their size
- The Commission should also review audit committee practices within private sector companies with a particular view on aspects of administrative burdens associated with a formal tendering process
- The European Commission should carry out an impact assessment on the rotation of auditors and the impact of voluntary joint audits
- Reinforced contingency plans should be designed to reduce the disruption that would be caused by an audit firm deemed "too big to fail" leaving the market
- Calls on the Commission to develop a pan-European liability regime for the auditing profession.
Following the vote of the European Parliament's Legal Affairs Committee, BDO CEO Jeremy Newman said: "The Committee has made many progressive recommendations on the reform of audit services. The demand for a more wide spread procurement process in the public sector along with a review of the administrative burdens of tendering in the private sector are crucial moves towards a more balanced and effective audit profession. Releasing more information about the quality of audit services at all firms, including the Big Four, will also help public sector entities, and others, recognise the quality of the work of BDO and others. "We are also delighted that the Parliament has called for a halt on the Big Four using their dominant position to takeover smaller firms and for a ban on commercial contracts which contain restrictive Big Four only clauses that everyone has recognised exist and which distort the market."The European Parliament has also rightly recognised that there are audit firms which are too big to fail and that contingency plans should be enhanced in case one should disappear from the market. Their call to remove the barriers of entry is good for the profession and the global economy."BDO will continue to offer our support to the Commission over the next few months as it draws up its plans for legislation".Ends

Are you a patient of James French, MD?
Reviews (8)
5 out of 5 stars Breast Lift with Implants
Reduction, Lift, Implants Needed for This 46 Year Young Mommy - McLean, Virginia
Show More Dr. James French is great. After having met with and interviewed eight doctors, I knew right away that Dr. French was "the one". Aside from his stellar credentials and his comforting bed side manner, there is something about Dr. French that makes you feel confident that you are great hands. With each interaction i have with Dr. French and his staff, It is confirmed that I made the right decision. Dr. French's staff is just as fantastic. Laura, Erin and Sherri care so much about how their patients feel. They take the time to listen and to understand. They are supportive and honest. They are very patient and kind. They are knowledgable and responsive. They make you feel good by just being with you. Starting with Dr. French, to his coordinator, to his nurses, to his front desk staff, I feel like they all know me and that I am a part of their family. I will expand upon my review at the completion of my experience, but so far, I can't imagine a better team for me!
5 out of 5 stars Tummy Tuck
24 Years Old, Two Kids. Full Tummy Tuck. - Annandale, VA
Show More Dr. French and his staff are GREAT! Dr. French explains everything in great detail, he also talks to you on a very real level, he doesn't make you seem like just another patient or money in his bank account. He and his staff are very friendly, they send lots of great follow up reminders and information and make you feel very welcome and comfortable either at the office or if you call and have a question.

Hello Everyone,
Interest for the Imagine Cup has been strong and we can confirm the various categories are now open for competition. From experience we know that the next couple of months will be key in getting great UK representation in the Imagine Cup.
Here are just a few of the reasons for encouraging your students to compete:
- PR: The Imagine Cup attracts the attention of both regional and national newspapers, together with technology and education press and news websites such as the BBC. Having students from your university compete in the Imagine Cup is great for raising the profile of your university in two important ways. Firstly it demonstrates the quality of your graduates to IT employers and makes them more attractive as employees (e.g. Dominic Green, UK winner of the 2008 competition) and secondly, it attracts new students to your university.
- Skills Development: Fundamentally the Imagine Cup is about helping students get real world experience with Microsoft technology. The skills learned during the various competitions compliment their studies and are invaluable when students apply for jobs with IT companies.
- Students Inspiration: With every technology interest area catered for, the competition is a great way to channel students' passion for technology out of class.
We want as many UK institutions and students to get involved with the Imagine Cup as possible, and to help you participate we provide:
- Giveaways for students: Every week we give away web cams and Starbucks vouchers. We also hold a monthly draw for a Dell laptop, providing everything a student needs to see them through their studies and the Imagine Cup competition.
- Donation of an Xbox 360 gaming lab kit for your university: The university with the most registrations will receive 4 Xbox 360s, 8 wired controllers and an assortment of the latest Xbox 360 titles. You are free to use them for XNA development or as a social/recreation area for students.
If you would like to receive regular updates on the registration numbers from your university then please let me know and I will happily send them to you. You can contact me by telephone (0118 909 3409) or if you prefer by email (mailto:email@example.com).
And just to give you an idea of how we are doing so far, here are the top fifteen universities with the highest number of registrations:
If you would like to know more, them please email or telephone me. I'll look forward to hearing from you.
Good luck,

TV It's on TV Tonight!
posted by April 18 at 14:43 PMon
In a blatant attempt to lure the nerdlings back to the fold, starting with tonight's episode, comic author Brian K. Vaughan (of Y: The Last Man) will be co-writing LOST (ABC 10 pm). You may now change your underpants.
Fox is replacing tonight's new episode of BONES (Fox, 8 pm) with a rerun, because of the plot is too reminiscent of the Virginia Tech shootings. Cue Simon Cowell to roll his eyes.
Speaking of AMERICAN IDOL (Fox, 9 pm) what about SANJAYA?? While Chris should get the boot for his cloying attempt at invoking sympathy from the Virginia Tech shootings, after Sanjaya's performance last nightwhich was even worse than usualTONIGHT COULD BE THE NIGHT WE FINALLY SAY BYE-BYE! (Sorry, Sanjaya, the "Aunt Jemima" will never top the "Pony-Hawk."

The top 5 business gadgets at CES 2010
Prepare to treat this sneaky work time reading as research - expense it against your taxable profits. CES may be the Consumer Electronics Show, but the discerning businessmen out there will have spotted an investment opportunity in one or two of the gadgets on offer.
But for those of you yet to make your first million, or even qualify with an MBA, here's our insider knowledge on the hottest technologies coming to market for boardrooms and business lunches the world over.
BlackBerry Presenter
- Type
- PowerPoint Streamer
- Connectivity
- Bluetooth to phone, S-Video & VGA
- Availability
- "At a later date" for $199
If a new BlackBerry device doesn't get you hot, then you're obviously not real jacket and tie material. RIM launched this BlackBerry accessory saying that it gives mobile professionals and management teams "the tool they need to deliver presentations successfully".
It's a 3.4 x 2.4 x 0.9-inch 140g device that connects to any BB phone via Bluetooth and then to any projector or monitor via VGA or S-Video cables. The idea is that all you swish business types can travel light, plug into whatever board room you find yourself in and explain how great your company is while flashing about your high-end smartphone too.
Light Touch Projector
- Screen
- 10-inch WVGA projection
- Connectivity
- Wi-Fi & Bluetooth
- Battery life
- 2 hours
- Storage
- 2GB + microSD slot
The Presenter may raise the odd eyebrow, but if you really want to seal the deal the moment you step into the room, then nothing will knock socks off at a business meeting quite like the Light Touch projector from UK company Light Blue Optics. No need for any baby toy cables this time. Just Bluetooth any files or internet access straight from your phone, or indeed over a Wi-Fi network, and this little treasure will project a 10-inch touchscreen display onto any surface at all. Yes, we did say touchscreen.
Sadly, it won't be available until an OEM picks it up, but you might know a guy who knows a guy or get some people to talk to some other people's people on this one to get the deal done, right?
Plastic Logic Que proReader
- Type
- 10.7-inch eBook reader
- Screen
- 8.5 x 11 inches, touchscreen
- Connectivity
- 3G & Wi-Fi
- Storage
- Availability
- $650/800
Of course, if you'd rather not faff around with projectors or another company's video set-up at all, then you can just go for a lovely big e-ink touchscreen display instead. This matte finish device also works very nicely, rather than having to lug about a brief case or heavy files it stores up to thousands of PPT, XLS, DOC and PDF files. Plus, you can also use it to read a copy of the Wall Street Journal/FT/copy of Private Eye while you're braving the commute.
IoSafe Solo
- Type
- Super-rugged SSD
- Size
- Connectivity
- USB/eSATA
- Availability
- Feb 2010 $499/749/1249
Nothing quite screams "important for business" like a hard drive that can withstand the super heat of a roaring fire, being left at the bottom of a lake for 30 days and an entire building collapsing on top of it.
This is the job of the IoSafe Solo and if the you still can't read the data on it after all the trauma, then the company will spend up to $5000 trying to recover it for you. It connects via USB and eSATA, provided either's still intact, and this military-grade armour plated device will work on Mac, PC and Linux. All contracts, spreadsheets and client accounts safe forever - well, for so long as you want them safe, of course.
- Type
- Gadget charger
- Technology
- Magnetic induction
Fresh from the damp squib of a release in 2009, Powermat has upped its game at this year's CES with the launch of some Powermat Li-ion mobile phone batteries and some new mats too. The rub is that you no longer have to attach a great big carbuncle of a case onto you mobile just so you can get it to charge up on your desk at work. The new batteries will take care of all that internally while keeping your phone slim and the line of your suit uninterrupted. Very neat indeed.

Black Ops 2: Nuketown Zombies exclusive to special editions, no pre-orders
Call of Duty: Black Ops 2 developer Treyarch teasers a piece of art yesterday that depicted the Nuketown sign plastered with blood and the word 'Zombies'. An Activision community spokesperson has clarified some confusion around the content.
The Activision rep explained on Twitter that while Nuketown 2025 and Nuketown Zombies are both bundled in the Care Package and Hardened editions of Black Ops 2, that both pieces of content are separate.
However, if you simply pre-order Black Ops 2 to receive the Nuketown 2025 bonus map, you will not receive Nuketown Zombies.
Here are the tweets:

Here's The Real Reason Putin Can't Let Go Of South And East Ukraine
REUTERS/Misha Japaridze
The output is vital to Vladimir Putin: 30% of Ukrainian military exports to Russia are unique and cannot currently be substituted by Russian production. And all military deliveries to Russia were suspended following the annexation of Crimea.
Bloomberg notes that Russia "would struggle without the 400 Ukraine-made engines it imports every year for its military helicopters or the $10 million it pays Ukraine to service its intercontinental ballistic missile system."
That's exactly why the Russian president would want to have these regions under Kremlin influence.
"Taking Ukraine's eastern and southern regions would be hugely beneficial for Russia from a military and economic point of view," Mikhail Barabanov, the editor-in-chief of the Moscow Defense Brief magazine, told Bloomberg. "Russia will have control of the very important and valuable defense companies and plants."
Separatists in the east already control the largest weapons cache in Europe: Over a million weapons including rifles, machine guns, and heavy weapons as well as millions of rounds of ammunition are stored in a facility built by the Soviet Union in the 1950s.
Furthermore, the port of Oktyabrsk in southwest Ukraine is critical for shipping Russian weapons around the world. This industry, run by "The Odessa Network," is not only economically valuable to Russia but also provides an important way for the Kremlin to exert power in proxy wars like Syria.
That is the primary reason Russia has an large investment in the rebels destabilizing south and east Ukraine: Putin's war machine relies on it.

The invention relates to apparatus and methods for tracking underwater acoustic signals and, more particularly, to an improved acoustic pulse detection and tracking system in an underwater ranging system comprising a number of hydroacoustic transmitters and receivers deployed along seismic sources and hydrophone cables for the purpose of determining their relative locations.
Hydroacoustic ranging systems are used to determine the relative locations of positions on hydrophone-arrayed seismic streamer cables and seismic sources towed behind ships performing marine seismic surveys. High-resolution surveys require accurate estimates of the locations of the seismic source and hydrophone receivers, which can be determined from the relative locations. Typical ranging systems capable of providing the required accuracy comprise a number of transmitters and receivers attached at various positions along the streamers. Individual transmitters and receivers or transceivers can also be installed on the platform supporting the seismic energy source, on head-end buoys, and on tail-end buoys. Ranges between pairs of transmitter and receiver locations are measured by the transit times of pulses transmitted at more or less regular intervals by the transmitters and received by the receivers. The ranges or the transit times are reported to a host computer for on-line estimation of the array and source locations or for storage for later off-line processing.
Commercial ranging systems are manufactured by Sonardyne of Hants, United Kingdom, Syntron, Inc. of Houston, Tex., and DigiCOURSE, Inc. of Harahan, La., a wholly-owned subsidiary of the assignee of this invention. Many of the details of the DigiCOURSE system for streamer location estimation are described in U.S. Pat. No. 5,031,159, issued Jul. 9, 1991, in the name of Robert E. Rouquette. Although the ranging system of Rouquette operates well, certain adverse conditions can cause problems. For example, in high sea states, the acoustic noise level increases relative to the signal level, making detection more difficult, especially at longer ranges. Variations in sea state and ambient noise conditions also degrade system performance.
Another significant problem is caused by the bubble curtain generated by the seismic source, the ship's wake, or propeller cavitation. For, example, the collapse of the large air bubble produced by the seismic blast sheds millions of small bubbles that trail the seismic source platform in the form of a bubble curtain. Consistent ranges through the bubble curtain are difficult to obtain because the bubbles attenuate the acoustic pulses and strengthen reverberation and forward scattering, thereby degrading pulse detection. The Sonardyne and the Syntron systems attempt to solve the problem by transmitting sequences of acoustic pulses and determining reception quality by the number of pulses from the sequence successfully received. One problem with that solution is that the total time required to transmit and receive the complete sequence of pulses is long and usurps valuable time needed with large acoustic networks to obtain all the necessary ranges. Furthermore, transmitter and receiver duty cycles are long, leading to increased power consumption and decreased battery life in typical battery-powered applications.
To solve the foregoing problems, there is a need for an improved acoustic ranging system usable in large acoustic networks and capable of producing consistent, high-quality ranges in a variety of adverse operating conditions, especially those characterized by high or varying ambient noise or by severe signal attenuation, reverberation, or forward scattering.
An improved underwater acoustic ranging system with novel pulse tracking satisfies this need. The pulse tracking apparatus is connected to an acoustic transducer, which converts impinging acoustic energy into electrical energy. A receiver, enabled during an adjustable time window, extracts pulse signals from the electrical energy. The extracted pulse signals represent individual acoustic pulses having predetermined characteristics and transmitted in response to a repetitive synchronizing event by acoustic transmitters located on streamer cables or other underwater apparatus. A pulse detector having an adjustable detection threshold characteristic selects the pulse signal whose amplitude exceeds the detection threshold by the greatest amount as the signal of interest. A reception time coincident with detection and relative to the synchronizing event is assigned to the signal of interest. The time of reception is used to adjust the detection threshold characteristic and the receiver time window in anticipation of the next expected pulse signal corresponding to the next synchronizing event.
In a preferred embodiment, the detection threshold characteristic is parabolic, with the vertex of the parabola centered within a detection window at a minimum threshold level. The tracking apparatus estimates the time of arrival of the next expected pulse from the times of reception of the most recent pulses. The estimated time of reception is a first parameter used to adjust the time position of the threshold characteristic. The width of the parabola and the depth of the vertex, or the minimum detection level, are adjusted with a second parameter representative of the quality of the foregoing estimates. Good estimates narrow the parabola and lower its vertex; poor estimates widen the parabola and raise its vertex. Measurements of the noise level taken when no pulses are expected are used to normalize the threshold characteristic. Thus, excellent discrimination of signal from interference and immunity from variations in ambient noise are achieved.
In another embodiment of the invention, the pulse tracking apparatus is joined with a matched-filter receiver using a replica of a pulse transmitted by remote acoustic transmitters and characterized by a high time-bandwidth product to extract the transmitted pulse from ambient acoustic noise. The preferred signal is a swept-FM pulse having a hyperbolic frequency-versus-time characteristic and a pulsewidth of about 10 ms. Such a pulse provides sufficient energy to penetrate the bubble curtain and exceed the noise level with high resolution for accurate ranging.
These and other features, aspects, and advantages of the present invention will become better understood with reference to the following description, appended claims, and accompanying drawings in which:

FIG. 1 shows an idealized plan view of an exemplary seismic survey deployment. A towing vessel 220 pulls two hydrophone-arrayed streamers 222A, 222B. Each streamer is outfitted with a number of associated hydroacoustic transceivers 236A-E, 236F-J attached at known positions. The head ends of the streamers 222A, 222B are marked by head-end buoys 226A, 226B. Tail buoys 230A, 230B attached by cable to the ends of the streamers 222A, 222B mark the tails. Underwater sleds attached to the tail buoys 230A and 230B include transceivers 236E, 236J. Transceivers could also be attached to the towing vessel 220 and to the seismic source 234. A network of acoustic ranges between pairs of transceivers is established, as exemplified by the in-line range 242 between transceivers 236B and 236C, the cross range 240 between transceivers 236B and 236G, and the diagonal range 244 between transceivers 236B and 236H. The ranges are determined by the transit times of pulses transmitted and received by the transceiver pairs. With transceivers, two-way ranges in which each transceiver of a pair receives a pulse from the other can be developed for better accuracy and quality. Alternatively, the transceivers could be replaced by individual transmitters and receivers at each position or by transmitters at some positions and receivers at others. In the latter case, only one-way ranges are achieved.
A preferred transceiver is a modified version of the transceiver described in aforementioned U.S. Pat. No. 5,031,159, which is hereby incorporated by reference. The preferred transceiver includes a transducer for converting hydroacoustic energy into electrical energy and vice versa. A transmitter portion of the transceiver synthesizes a pulse waveform having preselected characteristics on one of five channels between 50 kHz and 100 kHz. The synthesized pulse is transmitted into the water at a scheduled time through the transducer for reception by one or more of the transceivers. Each transceiver includes a matched-filter receiver matched to the set of transmitted pulses on the five channels. Times of arrival, or times of reception, of the transmitted pulses are assigned to the pulses as they are detected by the receiver. All times measured by the transceiver are referenced to the more or less periodic firing of the seismic source by a synchronizing signal communicated to the transceivers. Transit times and, therefore, ranges between pairs of transceivers can be determined by comparing times of reception with times of transmission, as described in detail in the incorporated patent. (Hereinafter, all times of transmission and reception are understood as referenced to the occurrence of an associated, generally regular synchronizing event, such as a synchronizing pulse communicated to each transceiver in coordination with each seismic shot.)
As shown in FIG. 2, an acoustic path defining a direct range RD between a first transceiver 250 and a second transceiver 252 can be occluded by, for example, a bubble curtain 254 produced by the collapse of the initial seismic bubble defining each shot. The small bubbles constituting the curtain 254 attenuate acoustic pulses transmitted through it, thereby making reception intermittent and degrading the quality of the ranges through it. In fact, often an acoustic pulse following a longer bottom-reflected path defining a range RB is received with a greater amplitude than the pulse along the direct path. If the less attenuated reflected pulse is mistakenly interpreted as the direct pulse, a range error of RB -RD results. Poor quality ranges can also occur whenever the ambient acoustic noise level rises relative to the signal level, such as in high sea states.
For developing quality ranges in the presence of adverse conditions, a ranging system having an adaptive detection threshold and pulse tracking is provided. A block diagram of the receiving portion of one embodiment of the invention, which represents an improvement over the receiver of the incorporated patent, is shown in FIG. 3. A transducer 260 converts hydroacoustic energy impinging on it into electrical energy amplified in a low-noise pre-amplifier 262. A bandpass filter 264 attenuates noise outside the signal passband, which is from 50 kHz to 100 kHz. The amplified filtered analog energy is sampled at a rate of 100 kHz and converted into a sequence of digital words by an analog-to-digital (A/D) converter 266. Upon accumulation of a frame containing a selected number, preferably 1024, of samples, the samples are time-reversed, padded with 512 null words on either side, and Fourier-transformed as indicated by block 268. The Fourier transform, as well as most of the subsequently described processing, is performed by a digital-signal-processor (DSP), such as the Motorola DSP56000, implementing a Fast-Fourier Transform (FFT) algorithm. Because the sampling rate is 100 kHz, the 50 kHz-to-100 kHz spectrum is effectively folded about 50 kHz into the 0 kHz-to-50 kHz band as described in the incorporated patent. The 2048-point FFT performs two functions. First, as indicated by block 270, the sampled data are channelized into five channels (Ch1-Ch5) each covering a separate 10 kHz band between 0 kHz and 50 kHz. The FFT also downshifts each of the five channels into a 0 kHz-to-10 kHz band (Ch1'-Ch5'), as indicated by block 272. The data out of each of the five channels of the FFT comprises about 205 points representing the complex conjugate Fourier transform X* of the input pulse on the associated channel for each sample frame. Each of the five channels is processed in parallel and identically. A description of one channel is sufficient. The complex conjugate Fourier transform X* of the input pulse is multiplied by a replica R of the Fourier transform of the downshifted signal expected by the receiver in a complex multiplier 274. A 512-point Fourier transform of the product RX*, blank-padded with 307 null words, is performed as indicated by block 276 and is combined with the results of transforms of consecutive frames of data performed by block 276 in an overlap-and-add processor 278 to produce a sequential measurement S of the correlation of the input energy with the expected pulse. The magnitude of the correlation is taken by a complex-magnitude block 280 to produce a sequential correlation measurement |S| of the signal level, if the pulse is present. When the pulse is known not to be present, such as just prior to the scheduled transmission of any pulses, the output of the magnitude block 280 represents the noise level No in the channel's band. Time decimation of 4:1 caused by the Fourier-transform processes results in a temporal resolution of 40 μs in the 100 kHz sampled system. There has been described to this point a five-channel, matched-filter receiver, the magnitude of the output of which is a portion of the autocorrelation function of the received pulse.
The receiver output signal representing underwater acoustic pulses, in this case, the correlation function of the received pulse, is compared with a time-varying, adjustable threshold in a detector 282. According to a preferred predetermined detection criterion, the point on the correlation function that exceeds the threshold by the greatest amount represents the detection of a pulse, to which a time of reception is assigned. The receiver can be enabled for reception of the pulse using a direct path and later enabled for reception of the pulse along a bottom-reflected path. The time of reception is indicated by TD for the direct path and TB for the bottom-reflected path. The times of reception are sent to a communications controller 284, such as a microcontroller in the transceiver, and transmitted to a central controller 286 on the towing vessel 220. The central controller 286 transmits a synchronization signal to the communications controller 284 to synchronize all the transceivers in the network periodically to the shots.
The shape and time position of the detection threshold characteristic are adjusted by threshold adjustment filters 288, 290. The first filter 288 adjusts the threshold characteristic for the direct pulse, and the second filter 290 adjusts the detection threshold for the reflected pulse. The filters 288, 290 also produce estimates TD, TB of the times of reception of the direct and reflected pulses during the next shot. From the estimates TD, TB, an aperture controller 292 controls the opening and closing of the detection windows of the detector 282 and, along with the estimates from the aperture controllers on the other channels, the on and off times of the A/D converter 266 and, thereby, the receiver.
The preferred detection threshold characteristic is illustrated in FIG. 4, which shows a family of threshold parabolas centered in time at the predicted arrival T of the next pulse. The width of the parabola is adjusted by changing its quality factor, or Q, from one shot to the next. The quality factor Q is a measure of the quality of the predictions of the times of reception of the previous few pulses. As the predictions improve, the quality factor Q is increased, narrowing the detection interval, or window, and lowering the threshold at the expected time of reception. As the predictions degrade, Q is decreased, widening the detection interval, and increasing the threshold at the expected time of reception.
The times of reception of the pulse for the previous few shots are used to develop an estimate T of the time of reception of the pulse during the next shot. The threshold adjustment filter associated with a given range, e.g., the direct-range filter 288, performs a least-squares fit of the previous four times of reception T0, T1, T2, T3 to derive an estimate T of the next time of reception, as shown in the example of FIG. 5. In a preferred version, the prediction equation used is T=a0 T0 +a1 T1 +a2 T2 +a3 T3, where a0 =2.25, a1 =-0.75, a2 =-1.25, a3 =0.75, and ao +a1 +a2 +a3 =1. Thus, the adjustment filter 288 is realized as a finite-impulse-response (FIR) digital lowpass filter. The estimate T is sent to the detector 282 to adjust the center of the threshold characteristic.
The adjustment filter 282 also establishes the quality factor Q according to Q=1/(ε0 2 +ε1 2 +ε2 2 +ε3 2), where εi =Ti -Ti, i.e., the difference between the actual arrival of the ith pulse and its previously estimated arrival. The Q value is also sent to the detector 282 to adjust the shape of the threshold characteristic for the next shot. In the event that no pulse is detected within the detection window the estimated time of reception is used as the reception time for purposes of estimating the next expected time of reception. For the purposes of threshold shape adjustment the quality factor Q is calculated as though a pulse were received at an edge of the detection window. Thus Q is decreased. Finally a null range is reported to the central controller, which recognizes null ranges as faulty.
The detection threshold parabolas shown in FIG. 4 are described by the equation Th=Tho e-bQ +cQ(ΔT)2, where Tho is the upper limit of the minimum threshold level, b is a constant related to the minimum threshold level at the highest allowable Q, c is a constant related to the width of the threshold characteristic, and ΔT is the independent variable representing the deviation from the predicted reception time of the next expected pulse. For a range of Q from 1 to 25, Tho =3No, a minimum threshold of 2No for Q=25, and a maximum width of ΔT=�0.5 ms at 6No for Q=25, b=0.0162 and c=0.64No.
The points at which the threshold characteristics reach the 6No level define the width of the detection window. For the example of FIG. 4, the narrowest window is �0.5 ms for a Q of 25, and the width for a Q of 1 is �2.2 ms. For Q values less than 1, the parabola flattens, but the full window is restricted to a user-selectable width for example, �20 ms. For Q=0, for example, at the start of pulse acquisition or after a range has been lost for a few shots, the threshold characteristic is given by a constant baseline level of 3No throughout a user-selected �20 ms window. It should be understood that the specific constant values given here are examples; other values are within the scope of the invention. Likewise, functions other than those described herein can be used to estimate T and to compute Q. Thus, it has been shown that the adaptive threshold characteristic can be adjusted in width and depth with a first parameter Q and can be offset in time with a second parameter T.
The threshold characteristic shown in FIG. 4 is normalized to the noise level No. At the start of each shot interval, prior to the expected arrival of any pulses, the noise level No of each receiver is measured and sent to the detector 282 to scale the threshold characteristic.
The performance of the adaptive threshold and signal tracking system is illustrated in the sequence of shot point frames in FIGS. 6A-6K. The signal 300, given by the peak of its autocorrelation function is shown to be stationary in shots 400-403, then to gradually retard in shots 404-407, and to again become stationary at a later time in shots 408-410. At the start, the degenerate parabola, or flat threshold characteristic for Q=0, open for a maximum window indicated by the vertical broken lines, is used. The reception of the pulse 300 in the center of the window increases Q and narrows the receiver window without adjusting T for the next shot 401. As the pulse remains stationary for the next few shots the threshold characteristic and the receiver window narrow as Q increases.
As the arrival of the pulse is gradually retarded in shots 404-407, the parabola broadens and retards in shots 405-408. As the pulse becomes stationary again in shots 407-410, the parabola narrows as Q increases, and finally centers on the stationary pulse arrival time in shot 410.
The preferred detection criterion is illustrated in FIG. 7. For the threshold characteristic 310 shown, a peak of the output of the receiver representing the actual signal 312 is shown coincident with the minimum threshold Tho. Another peak of the output of the receiver representing an unwanted interfering signal 314 is shown at a later time within the detection window. The amplitude So of the actual signal 312 exceeds the threshold Tho by an amount So -Tho, while the amplitude S1 of the interference 314 exceeds the corresponding threshold level Th1 by S1 -Th1. Although the interference level S1 is greater than the actual signal level So, the actual signal is selected by the detector 282 because the excess (So -Tho) of the actual signal 312 above the threshold exceeds the excess (S1 -Th1) of the interference level above the threshold characteristic. Thus, the detector is effective at discriminating between signal and interference.
As mentioned hereinbefore, the detector for each channel can be set up to receive a number of non-coincident pulses, such as a direct pulse 350 and a reflected pulse 352 arriving later on Channel 1 in the simple example depicted by the timing diagrams of FIGS. 8A-8C for only two channels. Similarly, each channel could be set up to track pulses received from a number of transmitters as long as the reception times are staggered, as exemplified by the pulses 354 and 356 received on Channel 2. After the synchronizing signal 358 is received, a first window 360 on Channel 1 is opened to receive the direct pulse 350. A little later a second window 362 is opened on Channel 1 to receive the reflected signal 352. On Channel 2, a first window 364 is opened to receive the pulse 354 and later a second window 366 is opened to receive the pulse 356, typically from a transmitter other than that transmitting the first pulse. As long as any window on any channel is open, the receiver is enabled (in the ON state as indicated by the RCVR timing diagram of FIG. 8C); otherwise, the receiver is disabled (OFF). Thus, each channel can have a number of non-overlapping reception windows and corresponding adaptive threshold characteristics for each range being tracked. After reception of another synchronizing signal 358', the process generally repeats itself with the windows tracking the expected times of reception of the corresponding pulses. Because the first pulse 354 on Channel 2 arrived early in the detection window 364, the window is advanced for the next expected arrival of the pulse after the subsequent sync signal 358'. The advanced window 364' on Channel 2 overlaps the first window 360' on Channel 1. The overlap is across channels and causes no problems. The receiver is enabled for a single long period 370 after the second sync 358', rather than for two shorter intervals 372 and 374 as for the first sync 358. Because the receiver is enabled by the logical-or of all the windows for all the channels and disabled otherwise, it serves lighter duty, and power is conserved. Furthermore, because the reception windows adapt to the signals being tracked, the windows are generally narrower than they would be for constant-width windows.
In an environment in which the direct path between transmitter and receiver is completely or intermittently occluded, a bottom-reflected path may be more stable. If the reflected ranges are of good quality, they can be used to qualify direct ranges of questionable quality or even to estimate a direct range based on knowledge of the geometry of depth of the sea bottom beneath the transmitter and receiver. In this way higher quality ranges can be achieved in difficult situations.
Another way the quality of acoustic ranges is improved, especially in noisy environments, is by increasing the time-bandwidth product of the selected signal set. Signals having large time-bandwidth products and characterized by high transmitted energy with a narrow autocorrelation function for good temporal resolution are desirable in this application. One such family of signals are FM-swept signals whose frequency-versus-time characteristics are exemplified in FIG. 9. Two kinds of FM signals are shown. The first is linear FM (LFM), for which the frequency varies linearly with time, i.e., f(t)=(f2 -f1)t/T+f1 0≦t≦T, where f1 and f2 are the lower and upper frequencies and T is the pulse duration. The other signal is hyperbolic FM (HFM), in which the frequency varies with time according to a hyperbolic function, i.e., f(t)=f1 f2 /[(f1 +f2)-t(2W/T)]for -T/2≦t≦T/2, where f1 and f2 are the lower and upper frequencies, W is the bandwidth, and T is the pulse duration. Details of both these signals are given in the article, " Time Coherence of Acoustic Signals Transmitted Over Resolved Paths in the Deep Ocean," by R. E. Williams and H. F. Battestin, J. Acoust. Soc. Am., Vol. 59, No. 2, February 1976. Both swept signals have large time-bandwidth products. In addition, the HFM signal is doppler-invariant so that the signal is not affected by motion of the transmitter relative to the receiver, which can provide a benefit with certain high-speed seismic source or receiver dynamics. Thus, the preferred pulse is an HFM signal of duration 10.24 ms swept over a 10 kHz range as shown in FIG. 9 for channel 2 (60 kHz to 70 kHz). Such a pulse has a time-bandwidth product on the order of 100 and an autocorrelation function with a main-lobe width of about 0.1 ms. Thus, the receiver compresses the 10 ms acoustic pulse into a 0.1 ms autocorrelation signal for high temporal and, consequently, spatial resolution. The complete signal set includes similar HFM signals on each of the five channels between 50 kHz and 100 kHz. Additional signal sets having similar qualities can be used to decrease interference between different sections of the streamer. For example, transmitters and receivers near the ends of the streamers could transmit down-swept HFM signals, while front-end devices could transmit up-swept HFM signals. Coefficients representing the FM pulses are stored in the transceiver and used to synthesize a pulse having a high time-bandwidth product, which is transmitted at the scheduled transmission time. In conjunction with the matched-filter receiver containing a replica R of the Fourier-transform of the pulse, a significant processing gain can be realized, thereby improving the detectability of the FM pulse over the preferred pulse of the reference patent.
Although the invention has been described in considerable detail with reference to certain preferred versions thereof, other versions are possible. For example, the signal representative of the underwater acoustic signal could be extracted by means other than the matched-filter receiver with pulse compression as described herein. An envelope detector could replace the matched-filter receiver in some simple applications, with the envelope, rather than the autocorrelation function, of the pulse compared to the threshold characteristic. Furthermore, the signal tracking and thresholding techniques described herein could find application in environments other than underwater acoustics, such as in radar. Therefore, the spirit and scope of the appended claims should not be limited to the description of the preferred versions contained herein.

American teen swimming sensation Missy Franklin took another step towards matching Michael Phelps' eight gold medal haul from the Beijing Olympics five years ago at the swimming world championships in Barcelona on Monday.
The 18-year-old cruised into Tuesday's final of the 100 metres backstroke, registering the fastest time in the semi-finals of 59.31 seconds to suggest that she could even threaten Gemma Spofforth's world record from the world championships four years ago.
Records though are not her principal target.
"I haven't thought about the world record," she said. "I'm just going to go out there, swim and have fun. I think when you reduce it down to a number you lose what it's really all about."
What does matter to the four-time gold medallist from the London Olympics last year is medals and she was given extra motivation by bumping into Phelps in the Catalan capital.
The most decorated Olympian of all time is not competing in Barcelona after retiring following the London Games, but Franklin insists he still remains an inspiration.
"I saw him yesterday and that was wonderful. We miss him so much, the team isn't the same without him, but we still have an incredible team and I think we are all excited to carry on his legacy.
"He has created a path in swimming which is such a bright light and will continue to shine for years and years to come.
"His legacy speaks for itself and we have to try and create our own."
And that is exactly what the California born swimmer is doing as she also attempts to add the 50 and 200m backstroke, 100 and 200m freestyle and the 4x200m relay and 4x100m medley relay to her first world championship gold which she claimed with her US teammates in the 4x100m relay on Sunday evening.
Another demanding day for Franklin starts early on Tuesday morning with the 200m freestyle heats and all being well she'll have to return to the pool for the semi-finals of the same event just minutes after the 100m backstroke final later in the evening.
Just as in London, the American's main competition in the 100m backstroke is likely to come from Australian Emily Seebholm after she qualified in second with another of the USA's glittering array of female stars Elizabeth Pelton and Japan's Aya Terakawa also expected to be in the medal hunt.

Psycho Suzi's Motor Lounge $10.50 2519 Marshall Street NE, Minneapolis 612.788.9069 Do you have the "it's getting cold, I am pulling out the parka, it's time to hibernate" blues? I know, man.

How can you make the best of it? Well, I think heading over yonder Northeast, sitting in a former A&W drive-in in a comfy booth and drowning your sorrows in a big bowl, built for two, filled with fruit juice, brandy, "secret sauce," and rum, lots o' rum, might just do the trick.
Psycho Suzi's, decorated all bamboo-y and tiki style, with lighting not seen since the Holiday Inn Holidome lounges of the '70s—what a perfect place to leave your worries behind.

Repeat TUR has not been shown to reduce relapse rates or prolong survival, but there is a clear rationale for seeking accurate staging information on which to base treatment decisions. Such information may change the definitive management options for patients and identify patients who are more likely to benefit from more aggressive treatment.
TUR with fulguration followed by an immediate postoperative instillation of intravesical chemotherapy followed by periodic intravesical instillations of bacillus Calmette-Guérin (BCG)
Intravesical BCG is the treatment of choice for reducing the risk of cancer progression and is mainly used for cancers with an intermediate or high risk of progressing.[6,13,14,15] An individual patient meta-analysis of randomized trials that compared intravesical BCG with intravesical mitomycin C (MMC) reported that there was a 32% reduction in risk of recurrence with BCG but only when the BCG treatment included a maintenance phase whereby BCG was given periodically for at least 1 year (typically an induction phase of six weekly treatments followed by three weekly treatments every 3 months).[14] Intravesical chemotherapy is tolerated better than intravesical BCG.[16,17,18,19,20] Although BCG may not prolong overall survival for Tis disease, it appears to afford complete response rates of about 70%, thereby decreasing the need for salvage cystectomy.[19] Studies show that intravesical BCG delays tumor recurrence and tumor progression.[20,21]
Evidence (immediate intravesical chemotherapy after transurethral resection):
- A 2004 meta-analysis of seven randomized controlled trials (1,476 patients with Ta or T1 bladder cancer) compared TUR alone with TUR followed by a single immediate intravesical instillation of chemotherapy.[7]
- The relapse rates were 48% with TUR alone and 37% for TUR plus intravesical chemotherapy (OR, 0.61; P < .0001). The risk of recurrence declined for patients with single (OR, 0.61) or multiple (OR, 0.44) tumors, but 65% of those with multiple tumors relapsed despite intravesical chemotherapy.
- Agents studied included epirubicin, MMC, thiotepa, and pirarubicin.[7]
- A subsequent multicenter, randomized, controlled trial confirmed the reduction in risk of recurrence. A 404-patient study reported a relapse rate of 51% for epirubicin immediately after TUR and a relapse rate of 63% for placebo immediately after TUR (P = .04). However, only small recurrences were prevented in this study, drawing into question the magnitude of benefit.[22]
- Similarly, another multicenter, randomized, controlled trial confirmed the reduction in risk of recurrence. A 305-patient study randomly assigned subjects to an instillation of epirubicin or no further treatment after TUR and reported relapse rates of 62% with epirubicin versus 77% in the control arm (P = .016).[8]
- The hazard ratio for recurrence was 0.56 (P = .002) with epirubicin. However, the main benefit was seen in patients at lower risk of relapse. Among patients at intermediate or high risk of relapse, the relapse rates were 81% with epirubicin versus 85% with no further treatment (P = .35).

My fiance chose this as his wedding band, since he wanted something thin, platinum, and simple. This fit the bill, and is a truely gorgeous ring! Beautiful shine. The product came quickly, and exactly as described. It is thinner than most men's rings, which is what he wanted, but may not be perfect for all.
- How did the image on site compare with the actual product? The actual product is much nicer.
- How accurate was the sizing? Accurate.
- Please tell us about the quality of the product. Excellent quality!
these rings are classy and very comfortable. i was reluctant to order these as i wanted a wider size ring instead both husband and i agreed these are great rings for anybody searching for wedding bands.

"...CNNs website this Friday falsely reported Apple CEO Steve Jobs suffered a heart attack."
So, I should have bought Apple stock on friday?
Nothing on Bill Maher's new movie?!?!? Man people, let me quote the last line of the movie: "Grow up or die!"
nine billion? Typo?
Obama is an embarrassment!?! Obama. Really. It is a complete mystery to me how that woman could be so deluded as to think that Obama is the the one who is an embarrassment to our country.
Don't put too much stock in that MN poll that shows Franken ahead of Coleman. That particular poll has a history of being skewed -- and wrong.
@3. Nine billion in market cap. Which was about a 9% drop in twelve minutes. Insane.
Yes, it is an embarrasment. And not to mention Obama's marinating in the hate America venom of Wrights's sermons for 20 years. Keep it up Sarah!
Ah, Russia. Putin is playing a game of Risk while the US is still playing Monopoly and the Presidential race is about to become a game of Clue.
raindrop @7:
Yes, it is an embarrasment. And not to mention Obama's marinating in the hate America venom of Wrights's sermons for 20 years. Keep it up Sarah!
I gotta agree with raindrop.
Israeli politician and Holocaust survivor Yitzhak Shamir once said, "Every Pole sucks anti-Semitism with his mother's milk," and Barack Obama has been sucking in America hatred since he was breast-feeding at his liberal mother's teet.
I'll tell you what I'm really afraid of though: that America-hating Barack Obama is going to do to this country what those other America-hating politicians--FDR and Bill Clinton--did to this country. Can this nation really survive the kind of job growth, economic stability, national security, energy independence, and health-insurance reform that Obama is secretly plotting to unleash upon us once he grabs the reins of power?
Oh, and before all you leftists start bashing me, I think we can all agree that America is much better off after eight years of "country first" George W. Bush than after eight years of "me first" Bill Clinton.
you keep up this fiction that liberals, leftists, and even radicals "hate" America.
And your side doesn't.
Yet it is yoru side that has wrecked our constitution repeatedly (remember Nixon?), that has started a trillion dollar war by "mistake," yeah right, that has weakened our economy thru the demonstrably idiotic notion of unregulated "free markets" which is 100% contrary to our founding fathers' ideals that we have democratic government to further our ability to pursue happiness, via majority rule, and your side openly consorts with terorrists and thugs like Oliver North (illegal actions for contras) and a CIA that overthrew democratically elected governments in Iran, Guatemala, Chile and lots of other places.
You sir, hate America. Not us.
As to Mr. Ayers, he was wrong for the bomb throwing phase but for decades he ahs worked on education reform. Add it up with pluses and minusses, then tell us all the vast amount of charity work you have done. But include your minuses of voting for GOP members who openly supported the crimes of Nixon, who trashed our constitution by pursuing ficticious impeachment of Billdawg and who openly supported the high crimes and misdememors of Bush et al.
I'm not sure whether you would come out more pro terrorist and anti American than Ayers, if yo exposed your long list o anti democratic foreign policy maneuvers and long standing support for right wing politicains who have abused our constiution over and over again -- Nixon, Reagan and Bush, to be precise.
You sir are the anti American.
Pls. make a note of it. And STFU.
Sarah Palin is a traitor, and her husband is a traitor. They were members of the Alaskan Independence Party, which wanted to allow Alaska to secede from the United States. That is treason, and they associated with other traitors in the AIP. You betcha' That's the kinda straight talk we've been cravin'.
Oh my God! That is the best comment I have ever read from PC!
Strong work John Bailo, err... I mean Susan, uhh... I mean PC! Yay!
by your analogy, i noticed that russia is the most intellectual of the three games. which is fitting because america and its policies are based on stupidity.
save the trees! elect cheney!
Oh Raindrop, you're so silly. Reverend Wright was a US Marine. He's accomplished more in his life than you ever will, and is beloved by more people than you can ever hope to be.
He is a fully functioning, contributing member of society who happens to be outspoken about the failings of our society. When he talks, people pay attention.
And you, Raindrop? You are just a troll on a blog. Kind of pathetic, don't you think?
Hey! What's wrong with being a troll on a blog?
So all you GOP hacks know: us leftists, including radical revolutionaries such as myself, do not hate America. I would leave if I did. We hate what the traitorous assholes in YOUR party have done to America.
"Our enemies are innovative and resourceful, and so are we. They never stop thinking about new ways to harm our country and our people, and neither do we."
Bush in Washington, DC on Aug. 4, 2005
History has proven so.
And who does Sarah pal around with, oh yeah the Alaska Independence Party, which sees as its ultimate goal seceding from the union. She repeatedly courted a secessionist group founded by someone who openly professed hatred of the American government and cursed our flag. Sarah's husband, Todd Palin, was a member of this group, for years!
In 1994, Palin attended the group's annual convention. And she addressed its convention this year, as an incumbent governor whose oath of office includes upholding the Constitution of the United States.
My oh my. What absurd extrapolations I set off by merely stating fact. Obama himself eventaully repudiated Wright.

Ukraine: The Clash of Manichean Narratives and a Way Out
In order to understand what is going on in Ukraine, history matters and the narrative of the other as well. Putin is a brutal leader yet his popularity rose as a result of the crisis. Not necessarily because he is a new Hitler as many argue but because he managed to inscribe his narrative in a Russian narrative with deep historical roots.
