Medical image registration is a common technique that involves overlaying two images, such as magnetic resonance imaging (MRI) scans, to compare and analyze anatomical differences in great detail. If a patient has a brain tumor, for instance, doctors can overlap a brain scan from several months ago onto a more recent scan to analyze small changes in the tumor's progress. This process, however, can often take two hours or more, as traditional systems meticulously align each of potentially a million pixels in the combined scans. In a pair of upcoming conference papers, MIT researchers describe a machine-learning algorithm that can register brain scans and other 3-D images more than 1,000 times more quickly using novel learning techniques. The algorithm works by "learning" while registering thousands of pairs of images. In doing so, it acquires information about how to align images and estimates some optimal alignment parameters. After training, it uses those parameters to map all pixels … [Read more...] about Algorithm Speeds Up Process for Analyzing 3D Medical Images

Depending on your level of expertise, web hosting, which is the task of making websites and web pages available to many users, can be either very simple of daunting. n this article we are going to explore the different types of hosting. Our experts have curated the best web hosting services of 2018While they all act as a storage place for your website, where they differ is the amount of storage capacity, control, technical knowledge requirement, server speed and reliability. These are the six types of web hosting you will most often come across: 1. Shared hostingPerfect for entry-level website hosting. This is where your website will be stored on the same server as multiple other websites, that could be anywhere between hundreds or thousands of others.All domains will share the same server resources, such as RAM (Random Access Memory - a type of computer memory) and CPU (Central Processing Unit – the “brains” of a computer). Costs of this type of … [Read more...] about What are the different types of web hosting?
Sections SEARCH Skip to content Skip to site index Subscribe Log In For the past five years, China has had the world’s speediest computer. But as of Friday, Summit, a machine built in the United States, is taking the lead. Summit, the world’s fastest supercomputer, is made up of rows of black refrigerator-size units that weigh a total of 340 tons. Credit Shawn Poynter for The New York Times Supported by BySteve Lohr June 8, 2018 Not so fast, China. America just won back bragging rights in the global supercomputer race. For the past five years, China has had the world’s fastest computer, a striking symbolic achievement that highlighted the nation’s ambitions and progress in high tech. But the United States has regained the lead thanks to a new supercomputer built for the Oak Ridge National Laboratory in Tennessee by IBM in a partnership with Nvidia. The speedy performance of the machine, called Summit, was … [Read more...] about You’d Need 63 Billion Years to Do What This Computer Can Do in a Second
Fun fact: a modern smartphone has greater computational capabilities than a typical home computer from a decade ago, yet requires only a fraction of the electrical power. Okay, maybe that's not a statement we'd file under "fun", but it is definitely a fact, and smartphones are only bound to get better – faster and smarter than they've ever been before.Hardly a surprise, the boost in performance brought by each consecutive smartphone generation comes thanks to a newer and better system-on-chip solution (a.k.a. SoC). This is the "brain" of your smartphone, containing the central processing unit (GPU) and the graphics processing unit (GPU), as well as an image processor, sound output circuitry, and a small amount of super-fast memory called cache, among other goodies – all on a single piece of silicon smaller than a penny. The Snapdragon 845: what we think we knowQualcomm's next flagship Snapdragon platform, likely to be called the Snapdragon 845, could be similar to the … [Read more...] about Snapdragon 845 chip rumors and expectations: what we know so far
