For a social scientist of a particular kind, the first thought that springs to mind in association with ‘inconsistency’ is Arrow’s famous impossibility theorem. The association is a natural one because, in the original formulation, inconsistency plays a double role in Arrow’s theorem. At the first level, the requirement that any aggregate ‘community’ ranking of social states be transitive is ak...

A resilience analysis of protection cycles (p-cycle) configurations for Double Rings with Dual Attachment (DRDAs) architectures is presented in this work. DRDAs are composed of two rings with corresponding nodes connected by two separated links. There are several possible configurations of p-cycles, which may be used in DRDAs for improving link or node protection upon link failure. The values o...

The most common approach for development, testing programs include some corrective actions during testing and some delayed fixes incorporated at the end of test. This paper presents an Extended model that addresses this practical situation given in the application part of sec 3.In this application the testing mode is considered as active mode and the delayed fixes mode as at the delivery. The r...

a r t i c l e i n f o Entrepreneurial intention is a rapidly evolving field of research, with a growing number of studies using entre-preneurial intention as a powerful theoretical framework. Some authors, however, are now calling for scholars to rethink the future of research on entrepreneurial intentions. This paper addresses this issue and, on the basis of a number of knowledge gaps in the l...

This paper discusses the reliability equivalences of a parallelseries system. It is assumed that the system components are independent and identical. Each has a constant failure rate. We assumed three different method to improve the system. Both the reliability function and the mean time to failure are used to derive two types of reliability equivalence factors. We also obtain the fractiles of ...

Expected lifetime and reliability of multilayer ceramic actuators were considered. 5 · 5 · 5 mm sized multilayer ceramic actuators with 60 ceramic sheet layers embedded internal electrodes were selected in this experimental analysis. Specially selected rectified AC bias was applied to the multilayer ceramic actuators to remove heating during charging and discharging process. Sixteen sets of mul...

These are notes from introductory lectures given at the Ecole Normale in Paris and at the Strasbourg meeting dedicated to the memory of Claude Itzykson. I review in considerable detail and in a hopefully pedagogical way the work of Seiberg and Witten on N = 2 supersymmetric SU(2) gauge theory without extra matter. This presentation basically follows their original work, except in the last secti...

One of the ultimate targets of lean manufacturing paradigm is to balance production and produce at takt time in production cells. This paper investigates the performance of a lean cell that implements the previous lean goals under uncertainty. The investigation is based on a system dynamics approach to model a dynamic lean cell. Backlog is used as a performance metric that reflects the cell’s r...

In this paper, we present new multi-year and 72-day mean seasonal-latitudinal tidal structures in exospheric temperature derived from joint analysis of CHAMP and GRACE accelerometer measurements. These results include diurnal tides DE3, DE2, D0, and DW2 and semidiurnal tides S0, SE1, SE2, SE3, SW4, and SW6. We also employ Hough mode extensions (HMEs) and the Climatological Model of Thermosphere...

In this paper, we consider the problem of modeling machine availability in enterprise-area and wide-area distributed computing settings. Using availability data gathered from three different environments, we detail the suitability of four potential statistical distributions for each data set: exponential, Pareto, Weibull, and hyperexponential. In each case, we use software we have developed to ...
