Three-parameter lognormal distribution has been demonstrated for applications in electromigration data analysis, especially for Cu interconnect structures with insufficient redundancy. Examples are given on estimating parameter values from experimental data using the maximum likelihood method. Detailed analyses are presented on confidence bound estimations of the parameters and their propagatio...

A citations analysis Purpose of this paper This paper addresses the question: should the world s top universities be led by top researchers, and are they? Design / methodology / approach The lifetime citations are counted by hand of the leaders of the world s top 100 universities identified in a global university ranking. These numbers are then normalised by adjusting for the different citation...

The authors develop a framework that incorporates projected profitability of customers in the computation of lifetime duration. Furthermore, the authors identify factors under a manager’s control that explain the variation in the profitable lifetime duration. They also compare other frameworks with the traditional methods such as the recency, frequency, and monetary value framework and past cus...

As reliability based methods gain increased acceptance, there is greater opportunity to use scarce resources more efficiently while maintaining a prescribed level of reliability of a structure throughout its service life. The goal is to provide management decisions that will balance lifetime system reliability and expected lifecycle cost in an optimal manner. This study proposes a system reliab...

In this paper I describe my approach to teaching introductory software engineering, a three-credit upper-level undergraduate course. What I believe is innovative is not the particular concepts or techniques but the way they are woven together, using the unifying concept of dependency management. The specific techniques I teach are the use of interfaces and factory design patterns. Interfaces ar...

Analytical models of object lifetimes are appealing because they would enable mathematical analysis or fast simulation of the memory management behavior of programs. In this paper, we investigate models for object-oriented programs such as Java and Smalltalk. We present analytical models and compare them with observed lifetimes for 58 Smalltalk and Java programs. We find that observed lifetime ...

The effective and sustainable environmental performance of a business is a result of various factors and most important the integrated outcome of the environmental management. Likewise, the integration of environmental protection into the armed forces functions has also gain interest for the military sector internationally. Therefore, the environmental management system (EMS) is recognized as o...
