Abstract:

Test vector compression is an emerging trend in the field of VLSI testing. According to these trends, increasing test data volume is one of the biggest challenges in the testing industry. In order to reduce on-chip storage as well as testing time ,the large volume of test data input is compressed in hybrid manner before being downloaded into the processer. Test compression involves compressing the large volumes of test data to small test sets that fit in the memory of Automatic Test Equipment. As the density of VLSI circuit increases, high test quality in smaller geometries can be achieved onl

Abstract:

The mechanical properties of a magnetorheological (MR) fluid in shearing, compression and shearing after compression have been studied in the magnetic field which is generated by a coil carrying different magnitudes of DC electrical current on a self-constructed test system. The relations of compression stress versus compression strain, yield stress versus compression stress were studied under different magnetic fields. The compressing tests showed that the MR fluid is very stiff at small compressive strains lower than 0.13. The shear yield stress of MR fluids after compression was much strong

Abstract:

ATPG vectors for a combinational circuit exhibit correlations among the bits of a test vector. We propose a BIST circuit design methodology using spectral methods which utilizes the correlation information. This circuit serves dual purposes. It generates BIST vectors that are similar to the ATPG vectors with higher test coverage as compared to random and weighted random vectors. The same circuit can also function as a test data de-compressor for compressed ATPG vectors applied from an external tester. Logic built-in self-test (LBIST) is now increasingly used with on-chip test compression as a

Abstract:

The drop-hammer compression testing method where the stroke is calculated by solving the equation of motions of the drop-hammer and anvil was improved in order to determine the strain-rate dependence of the elastic modulus of rubber material. An additional tool for interrupting the compression was embedded in the apparatus. The tool was a thick washer which informed the time when the prescribed compressive strain was achieved by the sharp increase of compression force. The oscillatory stress-time curve obtained by the load cell was appropriately smoothed employing the method of moving average.

Abstract:

A clinical test for scaphoid waist fractures is described in which the first ray is compressed longitudinally. This has the advantage that it can be done when the patient is in a plaster cast. Of 52 patients with suspected scaphoid fractures, 37 had negative tests and proved by X-rays then and later to have no fracture. 12 had positive tests and X-rays. Two patients with positive tests had fractures nearby: one of the scaphoid tuberosity and one of the radial styloid. One patient with a negative test had de Quervain’s disease. Once union has occurred, the test becomes negative.

Abstract:

Both the fiber push-in and the slice compression tests have been used to evaluate the interfacial properties of fiber-reinforced ceramic composites. Mechanics of sliding at the fiber-matrix interface obtained with these two tests are compared in the present study. While the interfacial radial stress induced by Poisson's effect is always compressive for the push-in test, it is tensile for the slice compression test when the fiber is stiffer than the matrix. This difference in Poisson's effect results in different interfacial frictional resistance between these two tests. Compared to the push-in

Abstract:

During the rice milling process, single and continuous compression occurs between brown rice and the processing parts. When the external load exceeds the yield limit of brown rice, brown rice kernels are damaged; with an increase in compression deformation or the extent of compression, the amount of damage to the kernels expands and accumulates, ultimately leading to the fracture and breakage of kernels. In order to investigate the mechanical compression damage characteristics of brown rice kernels under real-world working conditions, this study constructs an elastic–plastic compression model

Abstract:

Numerical specimens with ramdom joints is established by particle flow code PFC2D and uniaxial compression tests are conducted under three different loading rate. Studies have shown that strength of uniaxial compression are all increased with the loading rate no matter what specimen is complete or with random joints. The sensitivity of changes of uniaxial compressive strength of specimen with random joints decreases with increasing of the loading rate.

Abstract:

In this paper, the authors present a description of a new Web search engine model, the compressed index-query (CIQ) Web search engine model. This model incorporates two bit-level compression layers implemented at the back-end processor (server) side, one layer resides after the indexer acting as a second compression layer to generate a double compressed index (index compressor), and the second layer resides after the query parser for query compression (query compressor) to enable bit-level compressed index-query search. The data compression algorithm used in this model is the Hamming codes-bas

Abstract:

The materials used in a concrete construction have a major impact on its strength. But a lot of other things also matter, like the cement-water ratio (FAS), temperature fluctuations, curing conditions, and lack of compaction. The purpose of this study is to evaluate the findings of compressive strength testing of K-300 quality concrete using two different approaches: the non-destructive Hammer Test (HT) and the destructive Compression Test Machine (CTM). Both techniques were used to examine ten cube-shaped concrete samples that were 15 cm x 15 cm x 15 cm. The two approaches differed significan

Abstract:

Thixoforming is an alternative forming method, by which intricate and complex-shaped products can be manufactured using a single production step. This technology allows a material’s microstructure to be altered profoundly. Typical microstructure of steels processed in this manner consists of quasi-polyhedral austenite grains embedded in a ledeburite-carbide network. This type of microstructure was produced by processing the experimental material in this study: the X210Cr12 steel. Since austenite is a metastable component depending on oversaturation with a number of elements, its thermal and me

Abstract:

Elastomeric materials are used in the methods of plastic forming of sheets made of difficult-to-deform materials. This article presents the results of strength tests of selected elastomeric materials intended for sheet metal stamping. Polyurethane elastomers with a hardness of 50, 70 and 90 Sh A were used for the tests. The behaviour of the materials was determined in a simple compression test, a volumetric compression test and a uniaxial tensile test. In the case of the simple compression test, the values of the maximum force for a set punch travel of 3 mm were 1400 N, 2250 N and 4950 N for s
