This report describes a fully automatic placement tool for PCBs (printed circuit boards), nap (nonhierarchical automatic placement) that combines approaches from several different placement heuristics developed both for PCB and VLSI chip placement. Although the problem of placement for a PCB can be abstractly cast into the same formalism as the problem of VLSI cell placement, a practical tool m...

Programming distributed-memory machines requires careful placement of data to balance the computationalload among the nodes and minimize excess data movement between the nodes. Most current approaches to data placement require the programmer or compiler to place data initially and then possibly to move it explicitly during a computation. This paper describes a new, adaptive approach. It is impl...

Phasor Measurement Units (PMUs) are in growing attention in recent power systems because of their paramount abilities in state estimation. PMUs are placed in existing power systems where there are already installed conventional measurements, which can be helpful if they are considered in PMU optimal placement. In this paper, a method is proposed for optimal placement of PMUs incorporating conve...

Because of the more restrictive placement and routing constraints in Xilinx FPGA designs, conventional physical design tools for general placement and routing architectures usually do not work well for FPGA designs. Moreover, to generate high quality circuits which are easy to place and route, it is important to consider the specific physical design constraints during the technology mapping pro...

Despite the size and growth of the computer and video gaming industry – as well as the increasing use of the medium for the placement of advertising and product placement – researchers have neglected this area. By drawing on existing literature and research in similar and related areas of film product placement, sponsorship and interactivity, the authors present a conceptual overview and identi...

Data from the ALEKS-based placement program at the University of Illinois is presented visually in several ways. The placement exam (an ALEKS assessment) contains precise item-specific information and the data show many interesting properties of the student populations of the placement courses, which include Precalculus, Calculus, and Business Calculus, as well as two courses outside of the pla...

This thesis considers the placement problem in VLSI layout, which deals with layout optimization of integrated circuits. Most practical formulations of this problem are NP-hard. The most widely used formulations of this problem consider placement of rectangles within a rectangular container. The rectangles represent logical components and are called modules. Modules are connected by wires and a...

One of the mostly used enhanced oil recovery methods is the injection of water or gas under pressure to maintain or reverse the declining pressure in a reservoir. Several parameters should be optimized in a fluid injection process. The usual optimizing methods evaluate several scenarios to find the best solution. Since it is required to run the reservoir simulator hundreds of times, the process...
