As someone who has buying directly from Alibaba for a few years, I can tell you that consumers can buy direct from China with small orders of 1 or more for less cost than they can buy from nearly all American businesses. If, they’re willing to wait an extra week or maybe two for their bargains. Chinese businesses set up simple companies which buy bulk orders then parcel them out to American shoppers looking for bargains. Single items sell at a much higher price than bulk orders, obviously, but the Chinese stand to make huge gains by cutting out American middle men counterparts. Not only do they sell their goods direct from Alibaba, and Alibaba Express, but also on Ebay and Amazon. As these Chinese operations begin to sell more confidently & directly to American consumers, their focus will continue to shift away from B2B to direct marketing. Bezos knows formerly cheap slave-labor goods from China are becoming more expensive, which is one reason why he has invested heavily in India. The next Alibaba-type competitor (maybe Flipkart) will likely come from India.

A study was done on seventeen open-source and closed-source software showed that the number of vulnerabilities existing in a piece of software is not affected by the source availability model that it uses. The study used a very simple metrics of comparing the number of vulnerabilities between the open-source and closed-source software. [18] Another study was also done by a group of professors in Northern Kentucky University on fourteen open-source web applications written in PHP . The study measured the vulnerability density in the web applications and shown that some of them had increased vulnerability density, but some of them also had decreased vulnerability density. [19]

CT, Computerized Axial Tomography, uses x-rays to generate images of the body, including bone . In the CT scanner the x-ray tube, (source) rotates around the patient laying on the table. On the opposite side of the patient from the tube is the x-ray detector. This detector receives the beam that makes it through the patient. The beam is sampled via some 764 channels, (approximate number of channels). The signal received by each channel is digitized to a 16 bit value and sent to the reconstruction processor. Measurements are taken about 1000 times per second. Scan rotations are usually 1 to 2 seconds long. Each view/channel chunk of scan data is compared to calibration scan data of air, water and polyethylene (soft plastic), previously acquired in the exact same relative location. The comparisons allow the image pixels to have a known value for a particular substance in the body regardless of differences in patient size and exposure factors. The more samples or views, the better the picture.
