Power loss minimisation in distribution networks using fuzzy approach for system configuration

Studies indicate that as much as 13% of total generated power is wasted in the form of line loss at the distribution level [1]. One important area in which operating techniques of controlling distribution system losses are being applied is the area of network reconfiguration. Network reconfiguration refers to the closing and opening of switches in a power distribution system in order to alter the network topology, and thus the flow of power from the substation to the customers. Operating ...

Harnessing energy to improve mobility - and conquer the world

Engineers Ireland president Dr Kieran Feighan gave his presidential address in the organisation's headquarters in 22 Clyde Road, Ballsbridge, Dublin 4 on Thursday, 21 September. Here we provide a transcript of his speech. Read the second of this two-part series here. I will examine how harnessing energy to improve mobility has been the foundation for the development of many of the great empires in the world over the course of history. Mobility has a number of different facets. ...

Engineers report new way to make dissolving medical devices

Researchers from the University of Houston and China have reported a new type of electronic device that can be triggered to dissolve through exposure to water molecules in the atmosphere. The work holds promise for eco-friendly disposable personal electronics and biomedical devices that dissolve within the body. There are also defence applications, including devices that can be programmed to dissolve in order to safeguard sensitive information, said Cunjiang Yu, Bill D. Cook assistant ...

Nuclear technology after Fukushima - where do we stand now?

Nuclear power has made a substantial contribution to the world’s energy needs over the past sixty years, but it cannot be denied that it has had something of a chequered history during that time. The events at Three Mile Island, Chernobyl and Fukushima represent the major blots on its performance record. A quarter of a century passed between Chernobyl in 1986 and Fukushima in March 2011, with no significant nuclear incident having occurred in the interim. It was recognised that Chernobyl ...

Power quality in hospitals - minimising equipment failures and increasing patient safety

You may have seen a lot more people checking in at emergency departments or taking selfies from their hospital bed recently. It’s not that all your Facebook friends have suddenly been under the weather, it’s just that hospital patients and visitors are now allowed to use mobile phones on site without fear of interfering with medical equipment. However, hospitals still have a long way to go to reduce power quality issues. Power quality problems can be just as severe in medical environments ...

No battery, no wire, no problem - folding robots move without batteries

The traditional Japanese art of origami transforms a simple sheet of paper into complex, three-dimensional shapes through a very specific pattern of folds, creases and crimps. Folding robots based on that principle have emerged as an exciting new frontier of robotic design, but generally require onboard batteries or a wired connection to a power source, making them bulkier and clunkier than their paper inspiration and limiting their functionality. A team of researchers at the Wyss ...
