Compared to subthreshold leakage, dynamic power is normally much less sensitive to the process variation due to its approximately linear relation to the process parameters. However, the average dynamic power of a circuit optimized by deterministic glitch elimination (using hazard filtering and path balancing) increases because glitches randomly start reappearing under the influence of process v...

With the growing demand of very high bandwidth services such as high definition IP Television (IPTV), Service Providers (SPs) are moving to fiber-based solutions such as Passive Optical Networks (PONs) to meet current and future bandwidth needs. As these networks are deployed, coverage tends to directly affect Capital Expenditure (CAPEX) per subscriber served, with a minimum cost per Optical Ne...

A mixed integer linear programming (MILP) technique simultaneously minimizes the leakage and glitch power consumption of a static CMOS circuit for any specified input to output delay. Using dual-threshold devices the number of high-threshold devices is maximized and a minimum number of delay elements are inserted to reduce the differential path delays below the inertial delays of incident gates...

this paper studies the multi-stage supply chain system (msscm) controlled by the kanban mechanism. in the kanban system, decision making is based on the number of kanbans as well as batch sizes. a kanban mechanism is employed to assist in linking different production processes in a supply chain system in order to implement the scope of just-in-time (jit) philosophy. for a msscm, a mixed-integer...

this paper addresses the mixed integer reliability redundancy allocation problems to determine simultaneous allocation of optimal reliability and redundancy level of components based on three objective goals. system engineering principles suggest that the best design is the design that maximizes the system operational effectiveness and at the same time minimizes the total cost of ownership (tco...

During power system restoration, the planning of generator start-up sequence (GSUS) can significantly affect restoration efficiency. However, a GSUS optimization model based on mixed integer linear programming (MILP) cannot satisfy need for flexible re-energizing times transmission lines and serial generators. To solve this issue, new MILP-based is proposed in paper that generate scheme with li...

Increasing environmental restrictions, create stringent regulations for the use and management of rivers water bodies, thereby jeopardizing operational flexibility hydropower plants. The national plan new in Sweden is expected to be implemented 2025. Hence, it imperative producers consider alternatives which can overcome restrictions providing flexibility. In this paper, a Mixed Integer Linear ...

We investigate problems in penalized M-estimation, inspired by applications machine learning debugging. Data are collected from two pools, one containing data with possibly contaminated labels, and the other which is known to contain only cleanly labeled points. first formulate a general statistical algorithm for identifying buggy points provide rigorous theoretical guarantees when follow linea...

mathematical modeling of supply chain operations has proven to be one of the most complex tasks in the field of operations management and operations research. despite the abundance of several modeling proposals in the literature; for vast majority of them, no effective universal application is conceived. this issue renders the proposed mathematical models inapplicable due largely to the fact th...

This paper uses the weighted L$_1-$norm to propose an algorithm for finding a well-dispersed subset of non-dominated solutions of multiple objective mixed integer linear programming problem. When all variables are integer it finds the whole set of efficient solutions. In each iteration of the proposed method only a mixed integer linear programming problem is solved and its optimal solutions gen...
