Schelling's model is an influential that reveals how individual perceptions and incentives can lead to residential segregation. Inspired by a recent stream of work, we study welfare guarantees complexity in this with respect several measures. First, show while maximizing the social NP-hard, computing assignment agents nodes any topology graph approximately half maximum be done polynomial time. ...

One of basic system services that an electricity transmission system operator guarantees is power balance maintenance. The aim of this service is to keep power export/import to/from surrounding interconnected electricity transmission systems at a proposed value. The power quantity is a random variable. Therefore, a control strategy of the quantity consists in keeping amplitudes of a power balan...

The timing behavior of current and future embedded and distributed systems becomes increasingly complex. At the same time, many application fields such as safety-critical systems require a verification of worst-case timing behavior. Deriving sound guarantees is a complex task, which can be solved by Compositional Performance Analysis. This approach formally computes worst-case timing scenarios ...

internationalization is a matter of committed decision-making that starts with export marketing, in which an organization tries to diagnose and use opportunities in target markets based on realistic evaluation of internal strengths and weaknesses with analysis of macro and microenvironments in order to gain presence in other countries. a developed model for export and international marketing of...

Voxel based modeling is a very attractive way to represent complex multi-material objects. Beside artistic choices of pixel/voxel arts, representing objects as voxels allows efficient and dynamic interactions with the scene. For geometry processing purposes, many applications in material sciences, medical imaging or numerical simulation rely on regular partitioning space labeled voxels. In this...

We develop a general methodology for deriving probabilistic guarantees solutions of robust optimization problems. Our analysis applies broadly to any convex compact uncertainty set and c...

Export and the readiness to export constitute the first step of international marketing, which are affected by both internal and external factors of firms. One of the most important internal  factors is the presence of skilled personnel. The purpose of this study was to define the relationship between staff qualification and encouragment with the readiness level of Iranian pharmacuetical firms ...
