The need to integrate cost into the early product definition process as an engineering parameter is addressed. The application studied is a fuselage panel that is typical for commercial transport regional jets. Consequently, a semi-empirical numerical analysis using reference data was coupled to model the structural integrity of thin-walled structures with regard to material failure and bucklin...

What weight estimation method to choose in the Analytic Hierarchy Process is an important study subject, because each local estimate weight value depends on an employed weight estimation method and hence the global decision making result of the AHP, which is obtained by integrating estimated local weights, is also affected by the employed weight estimation method. The optimality of the weight e...

BACKGROUND Body contouring procedures following massive weight loss have become increasingly common and, unfortunately, continue to be associated with a high complication rate. OBJECTIVE To evaluate how weight loss method affects complications following abdominally based body contouring procedures. METHODS Patients undergoing abdominally based contouring procedures were retrospectively eval...

Given an edge-weighted graph G, let PerfMatch(G) denote the weighted sum over all perfect matchings M in G, weighting each matching M by the product of weights of edges in M. If G is unweighted, this plainly counts the perfect matchings of G. In this paper, we introduce parity separation, a new method for reducing PerfMatch to unweighted instances: For graphs G with edge-weights 1 and −1, we co...

A description is given of a simple, inexpensive and versatile method for estimating underwater weight. The use of a portable stock tank allows the determination of % Fat by underwater weighing without requiring a swimming pool, built-in tank, or special facility. Twenty-eight college students were weighed on two separate testing sessions 24-48 hours apart. Ten trials were performed at each sess...
