Dark matter is presumably made of some new, exotic particle that appears in extensions of the Standard Model. After giving a brief overview of some popular candidates, I discuss in more detail the most appealing case of the supersymmetric neutralino.

We discuss online strategies for visibility-based searching for an object hidden behind a corner, using Kurt3D, a real autonomous mobile robot. This task is closely related to a number of well-studied problems. Our robot uses a three-dimensional laser scanner in a stop, scan, plan, go fashion for building a virtual three-dimensional environment. Besides planning trajectories and avoiding obstac...

The theory of competitive auctions offers a coherent framework for modelling coordination frictions as a non-cooperative game. The theory represents an advancement over cooperative approaches that make exogenous assumptions about how output is divided between buyers and sellers and about the forces that bring buyers and sellers into local markets. Moreover, unlike price posting models, which fi...

The current study aims to explore the connections between business environments and firms' competitive priorities, which establish the basis for manufacturing strategy. This study explicitly considers the effects of asset and operating frontiers, as well as trade-offs across competitive priorities, a topic which has not been thoroughly studied by prior research. We collected data from 434 Chine...

Agglomeration of facilities that compete with each other is common in practice, which suggests the existence of forces driving facilities to locate in clusters. Shopping centers and food courts are everyday examples. Although these agglomeration forces have been adequately analyzed and explained in the economic literature, operational research location models have not taken them into considerat...

Selecting and implementing design tools and practices for use in the development of new products is more of a corporate bet than a guaranteed investment . Driven by the external forces of market opportunity, technological progress, and competitive pressure, manufacturing companies typically review available design tools and practices, hoping to choose those that will help produce a sustained co...

in this parer the iteration method (kani's method) is developed for the analysis of arch - frames. the method takes the effect of linear displacements of joints automatically into account. therefore, it is more efficient than moment distribution method. the iteration procedure can be applied to any kind of framed structure. a hand calculator or a computer may be used in the analysis of fra...
