We develop an ideal observer model of human visual shortterm memory. Compared to previous models that have posited constraints on memory performance intended solely to account for observed phenomena, in the present research we derive the expected behavior of an optimally performing, but limited-capacity memory system. We develop our model using rate–distortion theory, a branch of information th...

High-reliability organizations facilitate the reliable accomplishment of high-risk goals while avoiding catastrophe. Our paper evaluates natural gas utilities in United States against features high-reliability organization (HRO) theory. We ask: 1) How is organizational theory applicable to infrastructure? And 2) might hazards be reconsidered using HRO models industrial organization? conclude th...

Software Reliability Prediction techniques are Along with the existing 30 software measures, nine more measures are identified which results in the best performance of the software application. Predicting the reliability of software systems, failure data should be measured by different ways during the development process and its execution phases. This paper proposes a structure of reliability p...

It is a great honor for me to present this Opening Lecture at the World Reliability Forum. I was a young man when I jumped in the white water of a vivid stream of reliability theory and application creek. Late 50-s and early 60-s were really the time of reliability “Renaissance”. Since then reliability has been developed to a powerful applied mathematical discipline, with both, theoretical and ...

According to the spring’s failures in the tools storage and mechnical tools locking, the thesis will discuss the reliability optimization design for spring. With the known probability characteristics of basic random parameters, the random perturbation method, the reliability theory and optimal design technology are used to give the spring reliability design problems in locking knife spring in t...
