In this paper, we investigated a one-dimensional compactor based on a 45°-shear line technique with jogs insertion for a cell layout. The compactor can be connected off line from current commercial layout tools, such as Tanner Pro’s L-Edit, Cadence’s Virtuoso or Springsoft’s Laker, using the CIF format. A data structure of edge-linked adjacent matrix is constructed for easy implementation in ou...

We study the fixed parameter tractability of the counting version of a parameterization of the restrictive list H-coloring problem. The parameterization is defined by fixing the number of preimages of a subset C of the vertices in H through a weight assignment K on C. We show the fixed parameter tractability of counting the number of list (H,C,K)-colorings, for the case in which (H,C,K) is simp...

SUMMARY Roller compacted hydrophilic polymer combinations were used to formulate verapamil hydrochloride (HCl) extended release hydrophilic matrix tablets. The effect of roller compaction (RC) parameters on the properties of blended polymers, tablets and drug release were investigated. RC granulation improved the powder properties without affecting the pharmacotechnical properties or the drug r...

A multisurface glass roller bottle has been constructed for the growth of animal cells in culture. This bottle contains five concentrically placed glass cylinders that provide additional surfaces for the growth of animal cells. The bottle occupies the same space as a standard roller bottle, but it contains nine times the surface area of a standard bottle. L and HeLa cells can be grown in the bo...

Space compaction of test responses provides parallel access to functional outputs and reduces testing time and test data volume. We present a new space compaction approach that only uses information about the fault-free responses for a precomputed test set . It is, therefore, especially suitable for embedded cores. It does not make any assumption about an underlying fault model, and it does not...

Passive radiation shielding is one strategy to mitigate the problem of space radiation exposure. While space vehicles are constructed largely of aluminum, polyethylene has been demonstrated to have superior shielding characteristics for both galactic cosmic rays and solar particle events due to the high hydrogen content. A method to calculate the shielding effectiveness of a material relative t...

This paper addresses the problem of compacting test responses in the presence of unknowns at the input of the compactor by exploiting the capabilities of well-known error detection and correction codes. The technique, called i-Compact, uses Saluja-Karpovsky Space Compactors, but permits detection and location of errors in the presence of unknown logic (X) values with help from the ATE. The adva...

We are studying a hydraulic system design and vehicle dynamic modeling for a development of tire roller system, because those are very important in analysis of tire roller. Generally, tire roller is one of the useful machines in a road construction field and it technically applied for many other construction fields. Also, we conceptualize of new hydraulic and traction system, and define about t...

In this paper, a test pattern generation system for combinational circuits including test pattern generator, fault simulator, and test set compactor is introduced. The techniques that improve test pattern generation process are used in an implemented test pattern generation system called COM_TEST. The results of COM_TEST on ten circuits are given.
