This paper investigates technical and organizational tools to improve performances of a multi-state degraded system subject to multiple competing failure processes. The competing failure processes treated in this paper are oil insulating aging and electrical contacts wear out of high voltage oil circuit breaker. To degradation processes, is associated random shocks process highlighted by the st...

In this paper an analytical approach for the reliability evaluation of complex manufacturing system is presented, where a manufacturing system is in operative state only if its production capacity requirements are satisfied. We considered a manufacturing system with three types of failures namely type I, type II and type III failures. The proposed system works in four modes: normal, degraded, d...

This paper presents a detailed study of the nonuniform bipolar conduction phenomenon under electrostatic discharge (ESD) events in single-finger NMOS transistors and analyzes its implications for the design of ESD protection for deep-submicron CMOS technologies. It is shown that the uniformity of the bipolar current distribution under ESD conditions is severely degraded depending on device fing...

Workflow management systems (WFMSs) that are geared for the orchestration of enterprise-wide or even “virtual-enterprise”-style business processes across multiple organizations are complex distributed systems. They consist of multiple workflow engines, application servers, and ORB-style communication servers. Thus, deriving a suitable configuration of an entire distributed WFMS for a given appl...

Proteostasis refers to the regulation of the cellular concentration, folding, interactions and localization of each of the proteins that comprise the proteome. One essential element of proteostasis is the disposal of misfolded proteins by the cellular pathways of protein degradation. Lysosomes are an important site for the degradation of misfolded proteins, which are trafficked to this organell...

Following failures of primary aerodynamic actuators, safe flight can be maintained by introducing alternative actuation systems, such as secondary aerodynamic surfaces and propulsion, for critical stability and control augmentation. This paper presents an intelligent hierarchical flight control system architecture that is designed using nonlinear adaptive synthesis techniques and on-line learni...

Failure of remyelination is largely responsible for sustained neurologic symptoms in multiple sclerosis (MS). MS lesions contain hyaluronan deposits that inhibit oligodendrocyte precursor cell (OPC) maturation. However, the mechanism behind this inhibition is unclear. We report here that Toll-like receptor 2 (TLR2) is expressed by oligodendrocytes and is up-regulated in MS lesions. Pathogen-der...

Abstract Decadal changes in land use/land cover for Balachaur watershed in Nawanshahar district, Punjab, India were studied using black and white aerial photographs for March 1984 on approximately 1:20,000 scale and multidate geocoded false colour composites (FCC) of IRS-1D LISS-III on 1:50,000 scale for March 2002, September 2002, and May 2003 and interpreted visually to prepare land use/land...

A new three-hour lecture and a two-hour lab dealing with audio restoration have been introduced in the subject Audio Technology in the academic year 2005/2006 at the Department of Radio Electronics in Bratislava.
