Software Gives Strength-Testing System a Lift

SolidWorks 3D Design SoftwareDassault Systèmes SolidWorks Corp.Concord, MA800-693-9000www.solidworks.comSoftware from Dassault Systèmes SolidWorks Corp. has been used by engineering service company NTE-SENER to develop a system that tests the strength of astronauts who have completed prolonged missions in zero-gravity. The device, called the Muscle Atrophy Research and Exercise System (MARES), consists of an adjustable chair with a system of pads, levers, electronics, software, and a motor that assesses a dozen muscle groups for weakness and exercise benefits.

Machine Vision Aids Earthquake Retrofit Studies

As recent events in Haiti and Argentina have highlighted, many urban buildings in seismically active regions worldwide are in need of reinforcement to resist earthquake damage. One challenge facing earthquake retrofit activities is finding a balance between the cost and the effectiveness of the methods to be used. As part of its efforts to verify the efficiency and accuracy of new Italian regulations for the seismic assessment and repair to existing buildings, the European Centre for Training and Research in Earthquake Engineering (EUCENTRE, Pavia, Italy) used machine vision as a no-contact measurement system.

Embedded Vision System Increases Inspection Capabilities

Food manufacturers are held to strict agency regulations regarding product quality and consistency. Repeatable visual inspections are critical to ensure consumers receive a consistent and safe product. As regulations have increased, machine vision technology has become more intelligent to follow suit — a trend that some machine builders are using to their advantage.

Electromobility Drives Green Vehicles

Environmental friendliness, economy, and individuality are the fundamental ideas associated with the topic of eMobility (electromobility). The increasing scarcity of resources and constantly rising prices are being felt by everyone, as will be the follow-up costs if we don’t succeed in reducing environmental pollution such as greenhouse gas emissions. At the same time, the demand for individual mobility is growing, e.g. in big cities and the urban centers that surround them, in which around 40% of the world's population will live by 2015.

Using Parallel Processing on GPUs to Accelerate Finite-Difference Time-Domain Algorithms for Electromagnetic and Seismic Applications

Many scientific, technical and engineering applications in finance, medical imaging, modeling, simulation, and image processing can benefit greatly from the floating point acceleration offered by modern general purpose graphics processing units (GPGPU). Today’s graphics processors have evolved into sophisticated, massively-parallel, highly-programmable compute engines ideally suited for algorithms with a high degree of data parallelism. Combined with modern parallel programming languages and application interfaces such as industry standard OpenCL™, GPGPU offers a new paradigm for high-performance computing (HPC).

Using Multiprocessing in Industrial Automation Systems

Automated industrial control systems are an integral part of today’s manufacturing facilities. As these systems’ capabilities advance, the engineer shifts from someone who oversees processes to one who manages the data produced and functions performed by these systems to ensure product quality. Manufacturing systems need to be reliable, since downtime is an expensive alternative. Automation has reduced the number of people staffed at each facility so, if a system goes down, it’s probably not feasible for people to actually step in and move production along. If a system stops, so does production.
