A medical researcher has found the 2,500 year-old Pythagoras theorem could be the most effective way to identify the point at which a patient’s health begins to improve. The discovery was made after looking at data from ROC (Receiver Operating Characteristic) curves. These curves were initially developed during World War II for the analysis of signals to help operators decide whether a blip on the screen was an enemy target

Technology has changed rapidly over the last few years with touch feedback, known as haptics, being used in entertainment, rehabilitation and even surgical training. New research, using ultrasound, has developed an invisible 3D haptic shape that can be seen and felt.
Are the political parties really all that different from one another? Can politicians rig the vote in their favor by filling in their own profiles on the voting recommendation website "smartvote"? Two EPFL Ph.D. students applied data analysis methods to information collected from the Swiss democratic system.
It should come as no surprise to readers of this column that JMP is a personal favorite and, along with SAS, one of my most-used programs. There are a number of reasons for this. Of the many advantages that most packages can offer, breadth and depth of the statistics offered, quality of the diagnostics, interconnectivity of graphics with both data and analyses, and ease-of-use issues are uppermost in my mind as most desirable.

A study by an international team, including the University of Southampton, has shown population maps based on anonymous mobile phone call record data can be as accurate as those based on censuses. Their findings show maps made using mobile records are detailed, reliable and flexible enough to help inform infrastructure and emergency planners; particularly in low income countries, where recent population density information is often scarce.

Researchers at MIT, Microsoft and Adobe have developed an algorithm that can reconstruct an audio signal by analyzing minute vibrations of objects depicted in video. In one set of experiments, they were able to recover intelligible speech from the vibrations of a potato-chip bag photographed from 15 feet away through soundproof glass.
SigmaPlot Version 13 is a scientific data analysis and graphing software package with features that include Forest plots, which combine the results of like studies to improve statistical significance, and Kernel Density — a smooth probability distribution plot — as well as Analysis of Covariance (ANCOVA), which includes the effects of “nuisance” variables, and Principal Components Analysis (PCA) to determine the major data relationships.
Grapher 11 scientific graphics software is a 2-D and 3-D graphing program designed primarily for scientists, engineers and business professionals. It converts data into more than 60 fully customizable graph types. Features include polar vector plots, ternary class scatter plots, and 2-D and 3-D doughnut plots.
A stunning video based on fossils of a 410-million-year-old arachnid — one of the first predators on land — recreates the animal walking. Researchers used exceptionally preserved fossils from the Natural History Museum in London to create the video showing the most likely walking gait of the animal; the study is published in a special issue of the Journal of Paleontology.
Engineers and scientists from Pipistrel utilized HPC and technical computing resources to design and develop the Taurus G4 aircraft. The aircraft was conceived, designed and built in a mere 5 months, relying heavily on CAD and rapid prototyping techniques, but especially on the use of CFD and other computer aerodynamic tools for evaluation of flight performance and handling before committing to the building of the prototype.
Origin Viewer 9.1 is data analysis and graphing software designed to support OpenGL 3-D graph viewing. The standalone application allows viewing and copying of information from Origin Project Files without having Origin installed.
The scientists and inventors who make big-screen superheroes, spectacular explosions and other only-in-the-movies effects possible have their own Oscar ceremony. Kristen Bell and Michael B. Jordan hosted the film academy's Scientific and Technical Awards February 15, 2014, at the Beverly Hills Hotel, recognizing more than 50 of the most creative scientists and engineers in the movie business.
Surfer 12 scientific graphics software is designed to accurately transform data into presentation-ready maps. The gridding and contour mapping software, used by geologists, hydrologists and engineers, offers 21 different gridding methods, including Kriging with variograms, to convert irregularly spaced XYZ data into a uniform grid.
From a distance, these stunning images look likes stars exploding, fireworks or simply striking patterns — but what you’re actually looking at are the hidden dimensions of the World Wide Web. Dr. Martyn Dade Robertson from Newcastle University creates the stunning artworks, known as Data Portraits.
Origin and OriginPro 9.1 feature auto-positioning of labels in graphs, with the ability to add leader lines and to place labels arbitrarily such as attaching to data plot, to axes, or at fixed positions within the graph layer.
Investigators at Disney Research, Zürich have developed a method for using hundreds of photographic images to build 3D computer models of complex, real-life scenes that meet the increasing demands of today's movie, TV and game producers for high-resolution imagery.
When the San Diego Supercomputer Center (SDSC) at the University of San Diego, Calif., debuted Gordon early last year, the system’s architects envisioned that its innovative features — such as the first large-scale deployment of flash storage (300 terabytes) in a high-performance computer – would open the door to new areas of research.
UN-SCAN-IT Version 7.0 graph digitizing software for Windows is designed to make digitizing (x,y) graphs easier. Features include a zoomable and scalable digitizing screen.
AVS/Express 8.1 is a data visualization tool for both non-programmers and experienced developers, featuring rapid data analysis and rich visualization techniques combined with an intuitive, graphical application development environment.

Engineers at Stanford and the Monterey Bay Aquarium Research Institute have developed autonomous underwater vehicles that can photograph regions of the ocean floor that were once too risky for these robotic explorers.
The current trend to digitize everything is not lost on fine art. Documenting, distributing, conserving, storing and restoring paintings requires that digital copies be made
In late 2011, I wrote in Scientific Computing about the increasing collisions between commercial big data and data-intensive HPC. In the short time since then, the dimensions of these encounters have become clearer. This might qualify as the most serious rapprochement since business computing first branched off from scientific-technical computing in the early 1960s
