As video conferencing plays an increasingly critical role in many business environments, there is a need to ensure highly reliable operation of the conferencing infrastructure. We present a scheme for adding fault tolerance to an existing video conferencing server. The scheme is client-transparent so that it can be used by the installed base of clients. While the scheme is based on replication,...

Self-validating (SEVA) pneumatic actuator is a new generation of actuator which can not only give the corresponding output according to the input control variable but also give the accuracy of the control output and status of the actuator itself and other information. A dual processor system is implemented using C8051F060 and TMS320F28335 to acquire the signals and complete fault detection, dia...

With the development of automated and integrated large-scale industrial systems, accurate effective fault diagnosis methods are required to ensure security reliability running mechanical equipment. Due time consumption poor generalization performance conventional machine learning-based methods, deep learning (DL)-based have wider application prospects due their end-to-end architectural properti...

The complex operating environment of gearboxes and the easy interference early fault feature information make identification difficult. This paper proposes a diagnosis method based on combination whale optimization algorithm (WOA), variational mode decomposition (VMD), deep transfer learning. First, VMD is optimized by using WOA, minimum sample entropy used as fitness function to solve for K va...

The aim of our research is to develop a distributed system platform that supports a variety of tasks. Currently, we are implementing Internet applications on the system, including a service redirector, firewall, and web applications. These applications have different levels of dependability requirements. Depending on their criticality, a single task may execute on one or more computer nodes. So...

Due to the increasing complexity of modern circuit design, verification has become the major bottleneck of the entire design process. Most efforts are to verify the correctness of the initial Register-Transfer Level (RTL) descriptions written in Hardware Description Language (HDL).Major drawback of high level design methodologies such as RTL can be seen in the following facts. First, they lack ...
