Artificial neural networks have been used as predictive systems for variety of medical domains, but none of the systems encountered by Baxt (1995) and Dybowski & Gant (1995) in their review of the literature provided any measure of confidence in the predictions made by those systems. In a medical setting, measures of confidence are of paramount importance (Holst, Ohlsson, Peterson & Edenbrandt ...

In the past few years, the popularity of large-scale Internet infrastructure services such as AOL, Google, and Hotmail has grown enormously. The scalability and availability requirements of these services have led to system architectures that diverge significantly from those of traditional systems like desktops, enterprise servers, or databases. Given the need for thousands of nodes, cost neces...

T O D O :U pate gant nfo Abstract. An (n, d)-expander is a graph G = (V,E) such that for every X ⊆ V with |X| ≤ 2n − 2 we have |ΓG(X)| ≥ (d+1)|X|. A tree T is small if it has at most n vertices and has maximum degree at most d. Friedman and Pippenger (1987) proved that any (n, d)-expander contains every small tree. However, their elegant proof does not seem to yield an efficient algorithm for o...

A simulation study in construction management is business information that supports decision-making activities in construction planning and scheduling. To be confident in the various results of a simulation study, it is intuitive to be confident first in the collected simulation model inputs. This paper proposes properties to verify and validate simulation model inputs. The proposed V&V (Verifi...

The research reported in this paper complements previous work in the modeling and analysis of product development processes to reduce process risk and lead time. Such methods have found a receptive audience in industry, as evidenced by many academic case studies and the initiation of similar process improvement initiatives by the companies themselves. Given the ongoing ‘pull’ from a number of c...

In some statistical process monitoring applications, quality of a process or product is described by more than one ordinal factors called ordinal multivariate process. To show the relationship between these factors, an ordinal contingency table is used and modeled with ordinal log-linear model. In this paper, a new control charts based on ordinal-normal statistic is developed to monitor the ord...
