Abstract Paired comparisons are a popular tool for questionnaires in psychological marketing research. The quality of the statistical analysis of the responses heavily depends on the design, i.e. the choice of the alternatives in the comparisons. In this paper we show that the structure of locally optimal designs changes substantially with the parameters in the underlying utility. This fact is ...

This paper investigates the problem of allocation of database fragments to a network, so that the overall communication cost for processing a given set of transactions is minimized. Presented first is a data allocation algorithm with respect to a "simple strategy" to process transactions. Secondly, we present a dynamic data allocation algorithm which is guaranteed to produce a "locally optimal"...

nowadays the use of the switched reluctance motors (srms) has been considerably increased in various home and industrial applications. despite of many advantages of this type of motors, such as simple structure, low cost, and high reliability, the main disadvantage of them is the generation of high torque pulsation. this paper presents a novel method to optimize a typical srm such that the torq...
