in recent years, size of vlsi circuits is dramatically grown and layout generation of current circuits has become a dominant task in design flow. standard cell placement is an effective stage of physical design and quality of placement affects directly on the performance, power consumption and signal immunity of design. placement can be performed analytically or heuristically. analytical placer...

a new approach for pole placement of nonlinear systems using state feedback and fuzzy system is proposed. we use a new online fuzzy training method to identify and to obtain a fuzzy model for the unknown nonlinear system using only the system input and output. then, we linearized this identified model at each sampling time to have an approximate linear time varying system. in order to stabilize...

in this context, a novel structure has been proposed for simple differential evolutionary (de) algorithm to solve optimal recloser placement. for this, an operator is added to de algorithm to adapt concept of the problem. other contribution of this work is formulating a novel objective function. the proposed objective function has been formulated to improve four reliability indices which consis...

In distribution systems, in order to diminish power losses and keep voltage profiles within acceptable limits, network reconfiguration and capacitor placement are commonly used. In this paper, the Hybrid Shuffled Frog Leaping Algorithm (HSFLA) is used to optimize balanced and unbalanced radial distribution systems by means of a network reconfiguration and capacitor placement. High accuracy and ...

Analytical VLSI placement techniques achieved high solution quality and strong extensibility based on smooth approximation of placement objective and constraints. However, significant room still exist for VLSI placement to improve. We observe at least two sources of placement complexity and inaccuracy, namely, poor predictability for placement metrics and poor controllability of placement const...

regarding the nature of non-linear discrete placement, and in order to determine the optimal capacity of the substation, the goal in the present study will be a number of local optimum points. in this research, the problem of optimal placement posts to reduce power losses by considering distributed generation (dg). in formulating the objective function, geographical distribution density in the ...
