Submission + - Bosch Builds Non-Hybrid Engine Stop-Start System (greencarreports.com)

thecarchik writes: Autonomous engine stop-start systems, designed to save fuel by turning off a car’s engine when at a standstill, are increasing in popularity, especially in Europe, where fuel prices are often double what they are here. In many cases, the addition of an engine stop-start system can net fuel savings in the range of 5-10 percent. The challenge for engineers was to make the start process faster and more dynamic, as the time for declutching, changing gear, and re-engaging the clutch done in manuals is not available in an automatic vehicle. Early last year, German transmission specialist ZF showed off a new eight-speed automatic designed with engine stop-start capability and soon after that Audi launched a version of its dual clutch equipped A3 hatcback overseas with an engine stop-start system. Now automotive parts supplier Bosch has developed its own engine stop-start system that can be used reliably in automatics.

Submission + - Researcher addresses Google Street View privacy (physorg.com)

alphadogg writes: Imagine encountering leashed dogs without dog walkers, or shoes filled just with ankles — when scoping out potential apartments using Google Street View. These are the sorts of visual hiccups that an experimental computer vision system occasionally generates when it automatically removes individual pedestrians from images that populate Google Street View.

A University of California, San Diego grad student developed this proof-of-concept system, which is explained in a paper called “Removing pedestrians from Google Street View images.” http://vision.ucsd.edu/sites/default/files/IWMV_13.pdf The UC San Diego project explores one way that computer vision could be used to preserve privacy in public environments in our digital age.

The as-yet unnamed system removes pedestrians from urban scenes pulled from Google Street View — which provides panoramic views of cities, towns and rural areas across the world. Street views are constructed by stitching together overlapping images taken from a moving vehicle.

Submission + - Antilasers: Coherent Perfect Absorbers (aps.org)

I Don't Believe in Imaginary Property writes: "Researchers Y. D. Chong, Li Ge, Hui Cao, and A. D. Stone have designed a coherent perfect absorber—the 'antilaser.' While an ordinary laser emits light, the antilaser does the opposite: it is like a laser tuned to perfectly absorb light of a particular wavelength. To do this, they replace the gain medium of an ordinary laser with something that absorbs light, causing the process to look like a laser run backwards in time. So far, though, it's only a theoretical description and their next step is to actually construct one. Their research is available in their submission to the Physical Review Letters (abstract only, a subscription is required to view the PDF of the paper itself)."

I'm a data scientist at company that is big enough to have a six-person data science team. Our CTO bought the data science team all copies of this book (mine is sitting on my desk right now). The best thing about this book is the cover. Which is not to say that the book is terrible —the cover is a really pretty picture of a kiwi. The only chapter in this book that was really interesting was Chapter 5, "Information Platforms and the Rise of the Data Scientist", by Jeff Hammerbacher, who edited the book. The rest is pretty fluffy. Nice easy reading, but nothing really useful or all that interesting.
