Craig RosewarneCyber crime: A clear and present danger for SA
by
Craig Rosewarne, Information Security Group of Africa and Karel Rode, EMC2

Threats posed by cyber crimes have increased faster than potential victims - or cyber security professionals - can cope with them, placing targetted organisations at significant risk. Cyber crime is alive and kicking here in SA... (more)

Computing starts to evolve
by Roy Johnson, EngineerIT 
 
As we reach the upper limits of what can be achieved with silicon-based circuitry, new nanotechnologies are being explored, including DNA structures. The imminent demise of Moore's Law has been predicted before, yet silicon technology has always risen from its expected ashes to keep on increasing the number of transistors on chip wafers - generally in keeping with Moore's original prediction...  (more)
Website monitors World Cup cyber threats 
by EE Publishers staff reporter
 
Events like the World Cup soccer in Germany and the Olympic games in China have shown that competition is not just between the participating countries but also between cyber criminals. The only difference is that cyber criminals are competing amongst themselves to be the world's greatest threat to internet users... (more)
Storage checklist
by Herman van Heerden, Starship Systems
 
The storage landscape is a changing one, and there are a number of storage options available to businesses today. With the advent of network-attached storage (NAS) (traditionally file level access) and storage area network (SAN) (more focused on block level disk access) units, the notion that storage equals a hard disk is a thing of the past. Writing ones and zeros in an effective way has become an art... (more
Continued HSPA evolution of mobile broadband

by J Bergman et al, Ericsson, Sweden 
 
The success of mobile broadband is driving the demand for higher data rates and greater cell capacity. The industry is addressing this demand by evolving HSPA through 3GPP Releases 7, 8 and 9... (more)
Support for component manufacturers
by Hans van de Groenendaal, EngineerIT

In EngineerIT of August 2006 I questioned why component suppliers did not provide enough support for new developments and the smaller manufacturers. The editorial came about when I was involved in the design and building of an experimental module for SumbandilaSat... (more
IGBTs for solar inverter applications
by Wibawa Chou, International Rectifier, USA
 
The right combination of high-side and low-side bridge topology can ensure low power dissipation, high current carrying and gate-control benefits of IGBTs. Given the many varieties of advanced power devices available, choosing the right power device for an application can be a daunting task...
Thermal imagers detect energy waste in buildings
Information from Fluke
 
By the end of this year, thousands of European businesses will have to meet the new EU Building Directive, as well as many other energy efficiency regulations. Energy performance certificates (EPCs) will become mandatory within the EU for new buildings and large building refurbishments...

The many applications of laser technology
by Hans van de Groenendaal, EngineerIT
 
Lasers dominate our modern world - whether it is the tiny diode laser that drives our CD and DVD players, laser pointers or lasers used in eye and other surgery, or large metal-cutting lasers - the applications are many and varied... (more)
Measuring power production 
Information from Systems Automation and Management
 
 
Power utility companies need to accurately measure the power produced and used by their power stations on a 24/7 basis. The energy metering and data acquisition system (Emdas) has been a standard for Eskom over the past 15 years, and was recently redeveloped using the latest technology available... (more)
Process improvement project
Information from CSense
 
CSense Systems has successfully implemented a process improvement project at BHP Billiton's Worsley Alumina in Australia. This pilot project investigated the potential of an automated causal analysis system for process control, together with uni- and multivariate statistical process control... (more
Integrating building and energy management systems
by David Roberts, Schneider Electric
 
Building management Systems (BMS) have over the years become more sophisticated in capability and functionality but are still under-utilised. BMS have moved on from the days of the carousel projector through to fully animated 3D graphics, encompassing the world of the internet, embedded web servers at controller level and other modern technologies...

ROI study shows reduction in BMS payback time 
Information from Sitronix
 
Before the recent energy cost increases, the benefits of implementing a full-scale building management system (BMS) break-even point was typically three to seven years, depending on new or retrofitted design. Now the payback on these same buildings will drop to well under 18 months... (more
Radio amateurs set their sights on 500 kHz band
 
On 3 November 1906 the second Berlin International Radiotelegraphic Convention designated 500 kHz as one of the standard frequencies to be employed by shore stations and it soon became an international distress signal for shipping. Now over a hundred years later radio amateurs are seeking a secondary allocation in the region of 500 kHz... (more)
