Power electronics is becoming pervasive in electricity-based applications, making power device reliability an increasingly important topic. Maintenance operations are necessary to ensure the functioning of electronic apparatuses [1]. Guessing time for maintenance challenging due related tradeoff between costs and improvements. Lifetime prediction techniqu...

Wireless Sensor Networks (WSNs) are one of the fastest growing and emerging technologies in the field of Wireless networking today. WSNs have a vast amount of applications including environmental monitoring, military, ecology, agriculture, inventory control, robotics and health care. This paper focuses on monitoring and protection of oil and gas operations using WSNs that are optimized to decre...

Change definition and computation is an essential component in several capabilities of an active database, such as integrity constraints checking, materialized view maintenance and condition monitoring. We describe a method for change definition and computation, which is general and flexible. The method can be implemented easily in most active databases systems.

This article presents an Internet of Things (IoT) architecture suitable for large scale sensor networks for condition monitoring. The developed technology has been applied and demonstrated for rotating conveyor belt rolls. Wireless sensor networks is a relatively new and emerging technology, not only capable of addressing a large number of applications in industry but is also applicable for hom...

Advances in sensor technology have enabled companies to make significant progress towards achieving condition-based maintenance (CBM). CBM provides the opportunity to perform maintenance actions more effectively. However, scheduling maintenance at the unit level may imply a high maintenance frequency at the asset level, which can be costly and undesirable for safety reasons. In this paper, we c...

 Feto-placental infection or placentitis of unidentified etiology--34%. Of these, 17.8% were associated with bacterial infection.  Complications during birth--19%  Congenital anomalies including contracted foals--10%  No diagnosis--17%  Other causes included placental edema, premature placental separation, twins, umbilical cord anomalies, placental villous atrophy, body pregnancy, fetal di...

As an clean renewable energy source wind energy is highly regarded by various countries in the world. Wind turbine blade is one of the most important components in wind turbine. It is the key component for receiving wind energy. As turbine size steps up and the size of modern turbine blade increases, condition monitoring and maintenance of blades become more important. Strain detection is one o...

With the rapid growth of wind energy installed capacity, optimized maintenance has gained increasingly attentions from both researchers and wind farm owners. Conditionbased maintenance (CBM) has been introduced to the wind energy industry in order to ensure the availability and safety of the wind energy conversion (WEC) system, while minimize the operating and maintenance (O&M) costs. In this p...
