Long term contracts were at one stage considered as the most viable option to protect businesses against high annual increases. The rapid development of new technologies has changed all that - top technology and services today may be superseded tomorrow... (more)

Scalable energy data management systems integrated into PC-based control equipment cover everything from the building to the machine and even each individual motor. The only way to uncover all potential energy savings is by... (more)

The smart grid is the future of our power supply. Smart grids need smart buildings. Equipped with modern building automation, these buildings can be used as a counterbalance in the complex interplay between power generation and energy demand... (more)

Data centre, enterprise, and FTTx fibre networks present a number of challenges when it comes to locating and measuring events and impairments. These challenges include multiple connectors and splices in each fibre, numerous short jumper cables, and splitters... (more)

Modern photoelectric sensors typically employ one of two light technologies: either LED or laser, and the choice of light source can be as important for a reliable application as the choice of sensing mode, i.e. opposed, retro-reflective or diffuse... (more)

For measuring temperature, is it best to use a spot thermometer, a thermal imaging camera or a combination of the two? Well, essentially it depends on the job - whether you simply want to confirm temperature or investigate a wider problem... (more)

Electronic devices have been ubiquitous in modern life for some time. So it is perhaps easy to assume that everything necessary has already been accomplished in the world of passive components. As consumers, we are all well aware of faster computers, smarter phones... (more)

Power-supply efficiency is a critical criterion for today's cloud-infrastructure hardware. The efficiency of the chosen power solutions relates to system power loss and the thermal performance of integrated circuits (ICs), printed circuit boards (PCBs)... (more)

With the digital revolution now in full swing, online transactions, mobility, social media and big data continue to increase the amount of information being transmitted, stored and accessed by businesses and consumers anytime, anywhere and on any device... (more)

Mobile VoIP really is the next thing - the best thing. Gone are the early days of the technology when you were hoping that everything would work. Today, the quality is such that many of the purported "problems" have been solved... (more)
