Recently, several experimental studies have been conducted on block data layout in conjunction with tiling as a data transformation technique to improve cache performance. In this paper, we analyze cache and TLB performance of such alternate layouts (including block data layout and Morton layout) when used in conjunction with tiling. We derive a tight lower bound on TLB performance for standard...

In very deep-submicron very large scale integration (VLSI), manufacturing steps involving chemical-mechanical polishing (CMP) have varying effects on device and interconnect features, depending on local characteristics of the layout. To reduce manufacturing variation due to CMP and to improve performance predictability and yield, the layout must be made uniform with respect to certain density c...

This paper introduces ‘treatable’ theories, a large class of first-order theories each having a unique countable recursively saturated model.Important examples of such theories are DIS and DLO. It turns out that resplendency or parameter-free resplendency for such theories is implied by a Σ1(Π1 ThN)-statement. Other results concerning resplendency and Σ1definability are obtained.

Layout arrangement is important to achieve high productivity in flexible manufacturing system (FMS). This paper discusses the design of loop layout in FMS. The objective of the loop layout problem is the determination of the ordering of machines around a loop, to minimize the total number of loop traversals for a family of parts. This paper details the design, development and testing of particl...

This paper investigates the incorporation of optimization techniques early in the design process for the manufacturing process of printed circuit board (PCB) assembly. PCB design is a long process in which many sequential optimizations are performed with assembly optimization being the last. Since assembly optimization is not performed until the PCB design is completed it tends to be sub-optima...

Genetic Algorithms are widely used in many different optimization problems including layout design. The layout of the shelves play an important role in the total sales metrics for superstores since this affects the customers’ shopping behaviour. This paper employed a genetic algorithm based approach to design shelf layout of superstores. The layout design problem was tackled by using a novel ch...

the shape of wake behind a wind turbine is normally assumed to have a hat shape for the models used in wind farm layout optimization purposes; however, it is know from experimental tests and numerical simulations that this is not a real assumption. in reality, the results of actual measurements and detailed numerical simulation show that the velocity in wake region has a s-shape profile. the pr...

Genetic algorithm (GA) is proven to be a useful technique in solving optimization problems in engineering. Fixture design has a large solution space and requires a search tool to find the best design. Few researchers have used the GAs for fixture design and fixture layout problems. Either separately (Kulankara et al 2002) or along with FEM, GA has been used for fixture layout and clamping force...

Interactive method for optimization of an IC layout with respect to sensitivity to spot defects is presented. The relationship between occurrence of a spot defect and a circuit failure is discussed. A new concept of sensitive area is introduced. A new algorithm which allows determination of sensitive areas for opens is proposed. A practical example of the application of a software tool SENSAT t...
