Most existing integrated circuit (IC) reliability models assume a uniform, typically worst-case, operating temperature, but temporal and spatial temperature variations affect expected device lifetime. As a result, design decisions and dynamic thermal management (DTM) techniques using worst-case models are pessimistic and result in excessive design margins and unnecessary runtime engagement of c...

This paper presents a new bridge management system (J-BMS). It is integrated with a concrete bridge rating expert system that can be used to evaluate the serviceability of existing concrete bridges. The proposed J-BMS not only evaluates the performance of bridges, but also offers a rehabilitation strategy based on a combination of maintenance cost minimization and quality maximization. In this ...

Most existing integrated circuit reliability models assume a uniform, typically worst-case, operating temperature, but temporal and spatial temperature variations affect expected device lifetime.

Reactor pressure vessel (RPV), the only key component that can not be replaced in nuclear power plants (NPPs), is the main barrier against the radioactive leakage. The lifetime of NPPs is dependent heavily on the life of RPV, and thus, the aging and life research on a RPV is a key factor in determining the life extension of NPPs. The purpose of this paper is to introduce an aging and life manag...

Wireless Sensors (WS) mobility and pause time have a major impact directly influencing the energy consumption. Lifetime of WS Network (WSN) depends on consumption, thus, hardware software components must be optimized for management. This study aims to combine compact architecture with smart management efficiency in order increase ratio Lifetime/Energy Consumption, improve operating portable tra...

The lifetime of an operating system is long compared with that of its many varied applications and uses. General purpose or exible systems design are solutions that address such lifetime diierences. General purpose systems suuer from size and ineeciency. Flexible operating systems suuer from the overhead introduced by the mechanisms permitting exibility. Structured dynamic customization facilit...

This work have studied and developed lifetime estimation methods for the power transformer and how these could be used for asset management purposes. It is research performed in the intersection of the fields of reliability theory, statistical analysis, and stochastic process theory applied to lifetime estimations and management of transformers. The chosen approaches are the following. The thes...
