Permuted-block randomization with varying block sizes using SAS® Proc Plan Permuted-block randomization is often used in determining treatment assignments for clinical trials. This method allows flexibility in achieving balanced allocation of subjects among treatment groups and is further enhanced with increased randomness of the assignments by the use of varying block sizes. Chow and Liu (2004...

In this paper, Shortest Path Design Problem (SPDP) in which the path is incident to all cells is considered. The bi-directional path is one of the known types of configuration of networks for Automated Guided Vehi-cles (AGV).To solve this problem, two algorithms are developed. For each algorithm an Integer Linear Pro-gramming (ILP) is determined. The objective functions of both algorithms are t...

We describe a \topology advisor" for routing of critical (multi-source) buses in building-block design. The tool accepts as input a block layout, a two-layer routing cost structure superposed over the block layout, terminal locations for a multi-source bus, and source-sink delay upper bound (linear or Elmore delay) constraints for all terminal pairs. The b best routing solutions (b a user param...

Prelab The students begin with a prelab, where they examine the layout of the different circuit blocks. The students hypothesize which subcircuit will provide the best performance in each circuit block. They are also asked to explain their ranking to encourage the students to think about the effects of layout on matching. Experimental results may not exactly match the students’ predictions, but...

The facility layout problem is typically solved in what is referred to as a “top-down approach” of block layout design followed by detailed layout determination. However, a number of research efforts recently have challenged this approach, producing a “bottom-up approach to the facility layout problem” (Meller et al. 2004). In this paper we consider the bottom-up approach, applying a tighter fo...

Text block segmentation is necessary in document layout analysis. An algorithm and its implementation that segregates text block by block (a block is either a title or a paragraph) from the provided document, e.g. newspaper image, based on pyramid structure is described in this paper. The pyramid structure, which is amenable for parallel processing on output, is a multi-resolution image represe...

We present two implementations of dense matrix multiplication based on two different non-canonical array layouts: one based on a hypermatrix data structure (HM) where data submatrices are stored using a recursive layout; the other based on a simple block data layout with square blocks (SB) where blocks are arranged in column-major order. We show that the iterative code using SB outperforms a re...

This paper presents an integrated design approach for the facility layout problem. It develops a method for the concurrent determination of the block layout, the locations of departmental input and output (I/O) points using the contour distances between the I/O points, and the material flow paths between the I/O points. Results of computational experiments show that the performance of this inte...

Abstract On the basis of elaborating connotation intensive city block, it is pointed out that structure organization key to realize block. The order complexity block formed by close connection, overlapping elements, depth difference and their compound association. This paper constructs basic pedigree design from three levels street configuration, plot building layout, forms derivation comprehen...
