Black holes may be dark, but the areas around them definitely are not. These dense, spinning behemoths twist up gas and matter just outside their event horizon, and generate heat and energy that gets radiated, in part, as light. And when black holes merge, they produce a bright intergalactic burst that may act as a beacon for their collision.

Each audio file has its own history. Editing processes such as cutting and compressing leave their own marks, and this is what researchers use to detect manipulated recordings or plagiarized passages of music with the help of special software.
The fast Fourier transform, one of the most important algorithms of the 20th century, revolutionized signal processing. The algorithm allowed computers to quickly perform Fourier transforms — fundamental operations that separate signals into their individual frequencies — leading to developments in audio and video engineering and digital data compression.
Among the most common tools in electrical engineering and computer science are rectangular grids of numbers known as matrices. The numbers in a matrix can represent data, and they can also represent mathematical equations.
Jack Dongarra of the University of Tennessee will receive the ACM-IEEE Computer Society Ken Kennedy Award for his leadership in designing and promoting standards for mathematical software used to solve numerical problems common to high performance computing (HPC). His work has led to the development of major software libraries of algorithms and methods that boost performance and portability in HPC environments
David Brown has been the director of the Computational Research Division at Berkeley Lab since August 2011. An applied mathematician by training, his research expertise and interests lie in the development and analysis of algorithms for the solution of PDEs. His research has focused on adaptive composite overlapping grid techniques for solving PDEs in complex moving geometries and in the analysis of difference approximations for PDEs.
The Simpleware 6.0 image visualization, analysis and model generation software suite features a ribbon user interface and other features designed to accelerate the process of segmenting and meshing 3-D image data. These include boundary layers and mesh clipping for the creation of custom CFD inlets/outlets, as well as curved quadratic elements and a tet-to-hex converter.
The double delta wing is a simplified configuration used for studying aircraft aerodynamics. It is composed of a highly-swept delta wing connected in front of the main delta wing with a smaller sweep, reflecting the combination of a leading edge extension and the swept main wing. The aerodynamic performance of such wings, which includes the behavior of the leeside vortical flows at moderate and...
Tom Wong, a graduate student in physics and David Meyer, professor of mathematics at the University of California, San Diego, have proposed a new algorithm for quantum computing, that will speed a particular type of problem. But swifter calculations would come at the cost of greater physical resources devoted to precise timekeeping, their analysis has determined.
New, fast and accurate algorithm from the Institute of Physical Chemistry of the Polish Academy of Sciences in Warsaw, based on the mathematical formalism used to model processes accompanying interaction of light with gas planet atmospheres, is a major step towards better understanding of physical and chemical properties of materials’ surfaces studied under laboratory conditions.
Philadelphia, PA— The answer is yes, according to a paper in the SIAM Journal on Discrete Mathematics. In a paper published in the journal last month, authors Anthony Bonato, Dieter Mitsche, and Pawel Pralat describe a mathematical model to disrupt flow of information in a complex real-world network, such as a terrorist organization, using minimal resources.
The time may be fast approaching for researchers to take better advantage of the vast amount of valuable patient information available from U.S. electronic health records. Lian Duan, an NJIT computer scientist with an expertise in data mining, has done just that with the recent publication of "Adverse Drug Effect Detection," IEEE Journal of Biomedical and Health Informatics (March, 2013).
If you've ever registered for online access to a website, it's likely you were required as part of the process to correctly read a group of distorted letters and numbers on the screen. But there's a second type of captcha, and it may pose more of a security weakness
Faster, more secure logins for multimedia sites might be possible thanks to a new approach to Website and database security. Boolean logins would allow thousands if not millions of users to more quickly access the content to which they are entitled, such as music, video and images
Origin 8.5.1 features two data analysis Gadgets and a versatile graph reconstruction tool. These are a Cluster Manipulation Gadget and Quick Peaks Gadget
Andrew Lang once said disparagingly of someone: “He uses statistics as a drunken man uses lampposts — for support rather than for illumination.” This whimsical quote illustrates the goal of statistics, which is to provide insight for further action.
SYSTAT has long been a staple of the linear models crowd and now gets more powerful with every version. The present version includes Exact tests, Monte Carlo simulations, and the ever popular (and becoming more so every day) quality analysis section
NAG Library for SMP & Multicore is a commercial numerical algorithm library developed to harness the huge performance gains from the shared memory parallelism of SMP and multicore processors. Many of the algorithms, or routines, in the Library are specifically tuned to run on multi-socket and multicore systems
COMSOL Multiphysics version 4.0 features a user interface that makes the power of multiphysics simulation available to a wider audience of scientists and engineers. It is available with LiveLink options that integrate the program into the mainstream product design workflow
Maple 12 is all-purpose mathematical software that provides fully integrated numerics and symbolics. Live math is expressed in its natural 2-D typeset notation, linked to graphics and animations
In an advance that may impact the field of artificial intelligence, a new model developed at MIT can help computers recognize patterns the same way that humans do.
SigmaPlot 11 scientific graphing and data analysis software offers a full range of statistical functions in addition to graphing templates and utilities to facilitate data analysis for non-statisticians.
The JMSL Numerical Library for Java applications offers a collection of mathematical and statistical classes, and provides a scalable framework for tailored analytical applications, enabling users to create customized applications for data mining and predictive analysis of complex data.

Scientific Graphing and Analysis: Origin 7.5 becomes a contender in the novice-level analytic marketMarch 31, 2004 7:00 pm | by John A. Wass, Ph.D. | Articles | Comments
While not an X.0 major upgrade, version 7.5 contains enough new features to qualify for a significant upgrade. Origin is a graphics and statistics package that is slowly evolving into general data analysis software. The use of Wizards and other data access tools, enhanced ease-of-use, extended graphics and analytic capabilities, as well as programming and tool development functionality
Origin is the scientific software to combining presentation-quality graphics, the C language, and the NAG numerical library in a single package. Version 7.5 provides new timesaving tools that will simplify routine tasks, from importing data to creating graphs and applying detailed custom formatting.
