The distribution systems (DS) reconfiguration problem is formulated in this paper as a multi-objective mixed-integer linear programming (MILP) multi-period problem, enforcing that the obtained topology is radial in order to exploit several advantages those configurations offer. The effects of distributed generation (DG) and energy storage systems (ESS) are also investigated. To address the mult...

The imminent convergence of computer, communications, and consumer electronic products and market implies a need for optimization intensive techniques for synthesis of low power hard real-time systems. In this paper, we present a system-level approach for power minimization under a set of user-speciied costs and timing constraints of hard real-time designs. The approach simultaneously optimizes...

We study the action minimization problem that is formally associated to phase transformation in the stochastically perturbed Allen-Cahn equation. The sharpinterface limit is related to (but different from) the sharp-interface limits of the related energy functional and deterministic gradient flows. In the sharp-interface limit of the action minimization problem, we find distinct “most likely sw...

Objective: The objective was to establish the nature of choice in cognitive multitasking. Background: Laboratory studies of multitask-ing suggest people are rational in their switch choices regarding multitasking, whereas observational studies suggest they are not. Threaded cognition theory predicts that switching is opportunistic and depends on availability of cognitive resources. Method: A to...

This paper deals with minimization of the variances of the total discounted costs for constrained Continuous-Time Markov Decision Processes (CTMDPs). The costs consist of cumulative costs incurred between jumps and instant costs incurred at jump epochs. We interpret discounting as an exponentially distributed stopping time. According to existing theory, for the expected total discounted costs o...

Optimization of testing power is a major significant task to be carried out in digital circuit design. Low power VLSI circuits dissipate more power during testing when compared with that of normal operation. As the feature size is scaled down with process technology advancement, power minimization has become a serious problem for the designers as well as the test engineers. Test vector reorderi...

A common method to study the dynamic behavior of macroeconomic variables is using linear time series models; however, they are unable to explain nonlinear behavior of the series. Given the dependency between stock market and derivatives, the behavior of the underlying asset price can be modeled using Markov switching process properties and the economic regime significance. In this paper, a two-...

Reduced Ordered Binary Decision Diagram (ROBDD) is the most popular data structure for efficient representation and manipulation of Boolean functions. However, this novel data structure is very sensitive to the variable ordering, i.e. the size may vary from linear to exponential. Since finding the optimal variable ordering is an NP-complete problem and the best known algorithm has exponential r...

Code-switching is known to be a widespread phenomenon among bilinguals and in ESL/EFL teaching/learning process; it refers to any alternate use of two codes or languages within the same conversation or even the same utterance. The present study is an attempt to investigatethe functions, types and frequencies of code switching in students discourse in the context of ELT classrooms.The study also...
