Building design can be supported effectively by computer-aided design exploration. This paper investigates optimisation based on a mixed-integer super-structure representation of the search space of building spatial designs. It can take into account parametric as well as topological variations. In the suggested super-structure – the so-called supercube representation – discrete and continuous v...

The harmony search algorithm is applied to the optimum designs of functionally graded (FG)-carbon nanotubes (CNTs)-reinforced pipes conveying fluid which are subjected to a moving load. The structure is modeled by the Reddy cylindrical shell theory, and the motion equations are derived by Hamilton's principle. The dynamic displacement of the system is derived based on the differential quadratur...

For the early phase of conceptualization in the architectural design a case-based retrieval approach for finding building designs that have similar semantic and topological structures to a currently created one, can provide a helpful tool for inspiration and comparison of architect’s own ideas with the solutions available in a case base of previously created designs. The approach presented in t...

factorial and split-plot designs are two statistical procedures used to conduct agricultural field experiments. both designs are used frequently to quantify the main and interaction effects of two or more factors. however, split-plot design is recommended for specific situations depending on major and minor goals of the study, characteristics of the factors, and precision of statistical testing...

We examine prior and current sponsored search auctions and find evidence of strategic bidder behavior. Between June 15, 2002, and June 14, 2003, we estimate that Overture’s revenue from sponsored search could have been more than 60% higher if it had been able to prevent this strategic behavior. We also show that advertisers’ strategic behavior has not disappeared over time; rather, such behavio...

The development of the theory and construction of combinatorial designs originated with the work of Euler on Latin squares. A Latin square on symbols is an matrix ( is the order of the Latin square), in which each symbol occurs precisely once in each row and in each column. Several interesting research questions posed by Euler with respect to Latin squares, namely regarding orthogonality proper...

There is an increasing interest in the evaluation of prognostic and predictive biomarkers for personalizing cancer care. The literature on the trial designs for evaluation of these markers is diverse and there is no consensus in the classification or nomenclature. We set this study to review the literature systematically, to identify the proposed trial designs, and to develop a classification s...
