In practical decision making, one often is interested in solutions that balance multiple objectives. In this study we focus on generating efficient solutions for optimization problems with two objectives and a large but finite number of feasible solutions. Two classical approaches exist, being the constraint method and the weighting method, for which a specific implementation is required for th...

Thanks to advances in computing power and speed, designers can now generate a wealth of data on demand to support engineering design and decision-making. Unfortunately, while the ability to generate and store new data continues to grow, methods and tools to support multidimensional data exploration have evolved at a much slower pace. Moreover, current methods and tools are often ill-equipped at...

Following work of Stroud and Saeger, we investigate the formulation of the port of entry inspection algorithm problem as a problem of finding an optimal binary decision tree for an appropriate Boolean decision function. We report on an experimental analysis of the robustness of the conclusions of the Stroud-Saeger analysis and show that the optimal inspection strategy is remarkably insensitive ...

Despite their widespread use, the two main methods of assessing quality of life after surgery have never been directly compared. To support patient decision-making and study design, we aim to compare these two methods. The first of these methods is to assess quality of life before surgery and again after surgery using the same validated scale. The second is simply to ask patients whether or not...

With the improvement of living standards, consumers’ demand for wheat food is gradually diversified. Biscuit, as a kind convenience food, becomes consumer’s leisure snack due to its characteristics such low processing cost, easy-to-carry and convenient-to-eat traits, long shelf life, diverse varieties, rich tastes, which have attracted more people. Biscuits are composed four main ingredients, f...

This paper evaluates advantages of application of digital photogrammetry for the purposes of production of technical documentation for the objects under protection, comparing it with the classical photogrammetric procedures. Based on gained experiences, paper reviews procedures for the completely digital production of technical documentation. Process of making technical documentation is divided...

Three experiments examined the role of step-by-step and final-state diagrams in supporting object assembly. A total of 180 college students made origami objects from instructions consisting of text only, text plus a final-state (completed-object) diagram, or text plus step-by-step and final-state diagrams. In Experiments 1 and 2, construction accuracy in the final-diagram condition was comparab...

Communications Tipping large arrays of micrometer-scale dominos onto their side generates complex 3D topographies and arrays of nanoscale electrodes. These microdominos collapse in parallel when a shearing force is applied uniformly to an array of free-standing pillars. For more information, see the Communication by G. M. Whitesides and co-workers on the following pages.
