In the paper we propose a new method of test patterns compression based on SAT (SATisfiability) solving. By test patterns compression we can dramatically decrease test memory requirements for test patterns storing. This compression method is very suitable for scan-based digital circuits. Test patterns are decompressed in the scan chain during the test, no additional hardware is required. By thi...

In this work dynamic recrystallization behavior of AISI 403 martensitic stainless steel was studied using hot compression tests over temperature range of 900 C -1200 C and strain rate range of 0.001 s-1 - 1 s-1. The obtained flow curves showed that the hot compression behavior of the alloy is controlled by dynamic recrystallization. The flow stress and strain corresponding to the critical, pe...

The recruitment phenomenon, that is, the reduced dynamic range between threshold and uncomfortable level, is attributed to the loss of instantaneous dynamic compression on the basilar membrane. Despite this, hearing aids commonly use slow-acting dynamic compression for its compensation, because this was found to be the most successful strategy in terms of speech quality and intelligibility reha...

Ìn this paper, we propose two code based techniques: Variable-to-Fixed codes and Fixed-to-Variable codes for power efficient test data compression. The proposed scheme with the aim of achieving high compression ratio and low power consumption relies on reducing, the number of bits for representing the original test vector and the number of transitions per second. Simulation results on ISCAS‟89 ...

The semiconductor technology development makes it possible to fabricate increasingly advanced integrated circuits (ICs). However, because of imperfections at manufacturing, each individual IC must be tested. A major problem at IC manufacturing test is the increasing test data volume as it leads to high automatic test equipment (ATE) memory requirement, long test application time and low through...

in all engineering applications where solid surfaces slide on each other, friction plays an important role. it becomes even more important, particularly in metal forming processes where the two sliding materials are metallic. among forming processes, forging is an important process, because of improving material structure, mechanical properties and reducing production time. an inverse analysis ...

The proposed scheme, called the IOC-LP (input reduction and one block compression for low power test), compresses the test data of scan based SoCs to improve the compression ratio in the ATPG process. It does so by using the modified input reduction and novel techniques, a new scan flip-flop reordering for low power test, the newly proposed one block compression, and a novel reordering algorith...

One of the major challenges in testing a System-on-aChip (SOC) is dealing with the large test data size. To reduce the volume of test data, several test data compression techniques have been proposed. Frequencydirected run-length (FDR) code is a variable-to-variable run length code based on encoding runs of 0’s. In this work, we demonstrate that higher test data compression can be achieved base...

AIM To compare the 2-stage and 4-stage basic life support teaching technique. The second aim was to test if students' self-evaluated knowledge was in accordance with their actual knowledge. METHODS A total of 126 first-year students of the Faculty of Medicine in Ljubljana were involved in this parallel study conducted in the academic year 2009/2010. They were divided into ten groups. Five gro...
