Making Multicore Work With Minimal Pain Points

All major microprocessor vendors are introducing multicore architectures to deliver the latest installment of performance improvements and cost savings as required to remain competitive in the silicon marketplace. Indeed, multicore processors offer increases in processing throughput, savings in power consumption, and reductions in heat dissipation. However, some effort is required to fully exploit multicore benefits. Unfortunately, the transition to a multicore architecture is often best described by the old adage, “no pain, no gain.”

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.
