Radio frequency emission are considered incidental system noise in virtually all laptops, smartphones and other electronic devices, but scientists at Disney Research have found a way to use these spurious electromagnetic (EM) signals to uniquely identify even seemingly identical devices. …read moreContinue reading →
The post How to Choose the Right Industrial Control System first appeared on the ISA Interchange blog site.
This guest blog post was written by Tao Shen, a global product manager with Honeywell Process Solutions.
Finding the right control system for an industrial operation is a huge challenge. The longevity, expense and fundamental role the system plays in the plant’s productivity and profitability guarantee this.
Industrial organizations must maximize uptime, achieve high levels of reliability while controlling maintenance costs, and respond to challenges in terms of energy efficiency, regulatory compliance, and manufacturing agility. Any system must not just fit plant requirements today but accommodate growth and changes to the process or raw materials in future. Without this, sustainable growth is impossible.
As a result, a programmable logic controller (PLC) is likely to prove inadequate, with neither the control performance needed, nor flexibility to meet changing requirements. A distributed control system (DCS) offers significant advantages for modern industrial operations. To meet plant’s requirements and budget, however, it should be purpose-built for the industry and particular application needs.
I’d argue facilities need a control system that can demonstrate five key features:
Proven, yet innovative technology;
high levels of robustness;
specific control applications tailored to …read more
A team of researchers from Center for Biomedical Technology (CTB) at Universidad Politécnica de Madrid (UPM) has developed a pocket instrument capable of perceiving radio signals from 50 MHz to 6 MHz and storing this information in a non-volatile memory. After collecting and storing the information, the system assesses the daily exposure of a person to electromagnetic radiation. …read moreContinue reading →
Microbreweries and gourmet food businesses seem to be popping up everywhere. One food that is especially popular and requires careful preparation is dry cured sausage.
Dry cured sausage, also known as charcuterie, has become common in trendy restaurants, but has old world ties. Before mechanical refrigeration, the artisanal meat was dry cured for preservation. Today, the curing occurs mainly for taste, but similar methods are used.
Although sausages appear simple to make, they require very specific environmental conditions in order to remain safe and consumable. The main goal in curing is to create a highly acidic environment because most bacteria can not survive in an acidic environment. This process involves adding safe bacteria, or starter cultures, to the meat to cause the pH to decrease and become more acidic.
As well as the meat itself being a potential location for bacteria, so is the water within it. To counteract this, the moisture levels in the space where the meat is being dried must be monitored closely to ensure they remain low. This is why salt is often added to assist in the drying process. Typically, dry cured sausages will lose about 60-80 percent of their original weight.

A novel way of synthesising a promising new antibiotic has been identified by scientists at the University of Bristol. By expressing the genes involved in the production of pleuromutilin in a different type of fungus, the researchers were able to increase production by more than 2,000 per cent. …read moreContinue reading →
As mobile computing continues its pervasive adoption at home, the office and faraway places, both system versatility and affordability stand at the forefront of necessities that a user craves when choosing a new workstation. However, high-cost add-on components, coupled with inferior technology configurations, are the potential characteristics inherited from unreliable brands. Thankfully, Xi Computer Corporation delivers an intense portable computing experience with its PowerGo XT notebook, a hi… …read moreContinue reading →
Researchers from Imperial College London have developed a new synthetic method for producing molecularly designed polymer membranes that has the potential to make chemical separation processes up to two orders of magnitude more efficient than using conventional membranes. …read moreContinue reading →
Decked out in high-tech goggles, pilot Steve Zoumas dives low and sees the final gate zooming toward him: a 20-foot-tall metal-framed box ringed with neon. Boom! His sight goes black. The crowd lets out a collective “Whoa!” as pieces of his aircraft, which has just smashed into a concrete barrier, go flying. …read moreContinue reading →
