The utilization of renewable energy sources is a vital aspect for development of sustainability. Currently, an unexploited energy source is ocean waves. Various types of wave energy converters (WECs) are able to transform the motion of the waves into electricity. During the last 30 years, a wide range of prototypes was presented with different rates of success. The aim of this survey is to give an... View full abstract»

During recent years, silicon carbide (SiC) power electronics has gone from being a promising future technology to being a potent alternative to state-of-the-art silicon (Si) technology in high-efficiency, highfrequency, and high-temperature applications. The reasons for this are that SiC power electronics may have higher voltage ratings, lower voltage drops, higher maximum temperatures, and higher... View full abstract»

The analysis carried out in this article along with the proposed examples, highlighted that the practical(actually measured) performance figures of industrial communication systems are often worse than those expected, as derived from theoretical/simulative models. As could be seen, the causes of such discrepancies are mainly related to the internal behaviors of the employed components as well as t... View full abstract»

Since the wide adoption of database and Web service technologies in cross-enterprise manufacturing collaboration, leveraging deep Web contents through service discovery has become one of the most advanced trends in the manufacturing field. However, the effective service discovery and knowledge retrieval from manufacturing deep Web services is still a critical issue because of the underlying intric... View full abstract»

After they first appeared on the scene in the early 1900s [1], a series of improvements on vacuum tubes occurred in the second decade of the 20th century, leading them to maturity. A major advancement was introduced by an American chemist and physicist Irving Langmuir (18811957) of the GE Research Laboratory in 1912, who used his new mercury vapor diffusion pump to obtain high vacuum tubes. These ... View full abstract»
