Abstract The degraded performance of a power MOSFET affects customer system reliability and consumer perceptions of quality. Building a reliable product and associated application specific lifetime models to predict the suitability of a power device for a given solution can enable competitive advantages, increased quality, enhanced performance and result in market share gains. This paper describes the methodology employed to configure an application specific reliability test, the failure rates and modes observed, the package modelling, and design improvements implemented. The validation of such relative to its original form and competitor products is discussed where we demonstrate a doubling in performance and an approximate 50% increase in current handling capability. This type of analysis and application specific approach to innovation enables one to focus design improvements in areas most relevant to customer concerns while at the same time adding credibility to specified product limits.

Composite power system reliability involves assessing the adequacy of generation and transmission system to meet the demand at major system load points. Contingency selection was being the most tedious step in reliability evaluation of large electric systems. Contingency in power system might be a possible event in future which was not predicted with certainty in earlier research. Therefore, uncertainty may be inevitable in power system operation. Deterministic indices may not guarantee the randomness in reliability assessment. In order to account for volatility in contingencies, a new performance index proposed in the current research. Proposed method assimilates the uncertainty in computational procedure. Reliability test systems like Roy Billinton Test System-6 bus system and IEEE-24 bus reliability test systems were used to test the effectiveness of a proposed method.

The Bayesian Approach

Consider a parallel system with independent components. Assume that lifetime of i-th component follows exponential distribution with unknown parameter. We assume each , is distinct and the priori information can be modeled by quasi-density function given by , where is a predefined upper bound. A Bayesian estimator for , based on type-I censoring is used to get an estimate of system reliability. Optimal reliability test plan is designed, and an optimization problem is formulated satisfying usual probability requirements. Several numerical examples are considered to illustrate the Bayesian approach of obtaining optimal reliability test plan for a parallel system.

This study aims to analyze the value of the density of marine debris, perceptions and participation in Temberan beach and Pasir Padi beach, as well as determine the relationship of perception and participation to the density of marine debris. This research is a type of research that is descriptive with a mixed approach (quantitative and qualitative). The study was conducted at Temberan beach in Bangka Regency and Pasir Pasir Beach Pangkal Pinang in October 2019. The sampling technique used was random sampling and purposive sampling. The data collection technique was carried out using observation technique namely sampling and questionnaire. The validity test uses the Pearson Product Moment formula and the reliability test uses the Cronbach’s Alpha formula. The results showed that the density of debris in the Temberan beach was more dominant at 10.92 pieces/meter2, while at Temberan beach 3 pieces/meter2. The results of perception and participation are different, with the Temberan beach occupying more complex waste problems. The relationship of perception and participation in the density of marine debris have a relationship that affects each other.
