How does laser surgery compare with traditional surgery?

Laser Resurfacing FAQ's: Laser Resurfacing: Rochester, New Y...
Facial plastic surgeons use lasers on a routine basis. They use the laser as a "light scalpel." The tissue is left sterile and bleeding is greatly reduced. As in the example above, when the laser is used to treat port-wine stains, no cuts are made. The laser energy penetrates through the skin to shrink the abnormal blood vessels that are the cause of these marks. In this application the laser surgery can be performed without a traditional incision.

How does the audio guided tour work with a CD or Cassette?

Frequently Asked Questions
The tour follows a logical numbered route on your map and each place of interest on a CD is a different track. You need to pause the CD player when each section of commentary concludes, giving you time to explore, or when crossing streets. If you accidentally press STOP on a CD player it will return to the beginning, but you just select the appropriate track number for the next place you want to go to. With a cassette player you press STOP and PLAY accordingly.

Why does my audio have poor quality?

alphaWorks : IBM Toolkit for MPEG-4 : FAQs
Before Java 1.3, the audio support in Java was mainly for applets and was in officially undocumented classes such as sun.audio. In Java 1.1, the only support was for 8kHz u-Law Mono audio. So to play audio there, we have to "down sample" the content which results in loss of quality. We recommend that you use Java 1.3 or above; these versions use JavaSound, which provides much improved audio quality.

How does Microspinoscopy compare with fusions, conventional laminectomies and the artificial disc?

Frequently Asked Endoscopic Spine Surgery Questions
Results of all spinal surgery are similar in success rates. Fusions and conventional laminectomies offer 50 to 70% success rates while the artificial disc is around 67% success rates (per a recent study, although studies by the manufacturer reports success rates in the 80% range). Our surgeries are around 70% successful. Thus, the success rates are very similar but the recovery time, incision size and postoperative pain are greater with non-Microspinoscopy techniques.

How does MPEG video really compare to TV, VHS, laserdisc ?

MPEG-2 FAQ
VHS picture quality can be achieved for source film video at about 1 million bits per second (with proprietary encoding methods). It is very difficult to objectively compare MPEG to VHS. The response curve of VHS places -3 dB at around 2 MHz of analog luminance bandwidth (equivalent to 200 samples/line). VHS chroma is considerably less dense in the horizontal direction than MPEG source video (compare 80 samples/ line to 176!).

What audio quality does Siren14 deliver?

Polycom.com -Company - Siren14™/G 722.1C FAQs
Siren14 passes the audio band between 50 Hz and 14000 Hz, with excellent quality. Since Siren14 is a transform-based codec, and not a speech-model based codec, it handles music and natural sounds just as well as speech, and does not "break up" on non-speech signals like many speech-model based codecs. The 50 Hz to 14 kHz bandwidth covers 100% of the energy in human speech - this is approximately the same bandwidth as offered by FM broadcast radio.
