On March 4, 1999, the Wide-Field Infrared Explorer (WIRE) was launched from Vandenberg Air Force Base on a Pegasus XL launch vehicle into a 540 km orbit with a planned mission duration of four months. WIRE was designed to conduct a deep infrared, extra galactic science survey 500 times more sensitive than the Infrared Astronomy Satellite (IRAS) Faint Source Catalog. The instrument consists of a...

Overview: Emerging wireless networks will contain a hybrid infrastructure based on fixed, mobile and adhoc topologies and technologies. In such a dynamic architecture, we define information assurance as the provisions for both information security and information availability. The implications of this definition are that the wireless network architecture must (a) provide sufficient security mea...

According to the Just War tradition a war can only be just if two sets of principles are satisfied. First there is the jus ad bellum. These principles tell us when it is just to start a war. There has to be a good reason or a just cause in order for a war to be morally permissible (self-defense, defense of others, putting a stop to human rights violations). The decision to go to war has to be t...

Li MAS NMR spectroscopy was used to study the failure mechanisms of LiNi0.8Co0.15Al0.05O2 electrodes in Li-ion cells. Three sets of electrodes with different degrees of power fade (0%, 9% and 23%) were studied. The three electrodes were charged to various states of charge (0%, 40%, 60%, 80% and 100%) in pouch cells which were subsequently disassembled for NMR analysis. The lithium NMR shifts of...

Reliability analysis for packaging of beer production over a period of 9-month was carried out. The most important failure modes were identified and the descriptive statistics at failure and machine level were calculated. Several theoretical distributions were applied and best fit of failure data was identified. The reliability and hazard rate models of the failure data were determined to provi...

A Machine Learning (ML) System known as ROAMS (Ranker for Open-Auto Maintenance Scheduling) was developed to create failure-susceptibility rankings for almost one thousand 13.8kV-27kV energy distribution feeder cables that supply electricity to the boroughs of New York City. In Manhattan, rankings are updated every 20 minutes and displayed on distribution system operators’ screens. Additionally...

Introduction: The term glaucoma refers to a group of diseases that have a characteristic optic neuropathy with associated visual field loss in common. Intraocular pressure has been considered to be the only causal factor for glaucoma and the only factor that can be manipulated to alter the course of the disease. But considering high intraocular pressure as the only factor responsible for glauco...

The entity of Chiari formation was described by Hans Chiari in 1891 [1,2]. Since then the subject has been evaluated elaborately by a number of authors. However, it may only be correct to state that confusion in the understanding of pathogenesis and the nature of anomaly, significance of associated  abnormal soft tissue and bone anomalies and more importa...

-This paper provides a comprehensive survey on the state-of-the-art condition monitoring and fault diagnostic technologies for wind turbines. The Part I of this survey briefly reviews the existing literature surveys on the subject, discusses the common failure modes in the major wind turbine components and subsystems, briefly reviews the condition monitoring and fault diagnostic techniques for ...
