This paper presents an analysis of the impacts of electronic commerce on proactive firms in the connectivity equipment industry. Electronic commerce initiatives identified in the optical connectivity value chain were analyzed for each of the four layers of the chain namely network operators, system integrators, assemblers and sub-assemblers. In this industry, electronic commerce has been and wi...

The influence of voltage and current harmonics on equipment connected to electrical supply systems can cause serious problems. This paper presents a synopsis of the problem. The equipment most sensitive to harmonics is considered, such as -asynchronous motors, synchronous machines, transformers, capacitors, ripple control receivers, electricity meters, radio receivers, TV-sets, electronic contr...

In order to improve the validity of electronic equipment condition monitoring, overcome the shortage of normal KPCA (Kernel Principal Component Analysis) and SVDD (Support Vector Data Description) monitoring model, a method on electronic equipment condition monitoring based on KPCAEDA (KPCAEstimation of Distribution Algorithm) and MMSH-SVDD (Maximal Margin Separating Hypersphere SVDD Mode) is p...

Waste electrical and electronic equipment (WEEE) has been one of the fastest growing waste streams worldwide. Effective and efficient management and treatment of WEEE has become a global problem. As one of the world's largest electronic products manufacturing and consumption countries, China plays a key role in the material life cycle of electrical and electronic equipment. Over the past 20 yea...

As our society makes the transition into the digital age, electronics manufacturers are constantly pushing newer and better electronic equipment onto the market to satisfy customer demands for newer technology. Yet when this new stream of products makes its way into homes, older electronic equipment will, as a consequence, be discarded. Currently, several manufacturers have begun to initiate pr...

The international standard for functional safety of systems involving programmable-electronic components, IEC 61508, has been valid since the late 1990's, and Version 2 has just become valid [IEC10]. The scope of the standard is, generally, everything except avionics and medical equipment. It is based on the approach, novel at that time, of quantifying and reducing risk until it is acceptable, ...
