This paper proposes a new test data compression method for low power testing. To improve compression ratio, the proposed scheme uses the modified input reduction and novel techniques, a new scan flip-flop reordering algorithm and a newly proposed one block compression. The proposed method leads to better compression ratio with lower hardware overhead and lower power consumption than previous wo...

A hybrid system consisting of vapour compression unit, a liquid desiccant system, and a flat solar hot water collector were designed, fabricated and tested. This combination allowed for a separate control of humidity and temperature without energy penalty. Various packing heights of the absorber component were tested to determine the optimal performance of the combined unit. A 1000 mm packing h...

A hot compression test of new Al-6Mg and Al-8Mg alloys was conducted to understand the dynamic recrystallization (DRX) behavior by Mg contents. To investigate workability Al-Mg with high contents, deformation analyzed a in temperature range 300–450 °C, strain rate 10?3–100/s. Subsequently, high-temperature investigated through processing map microstructure observation. In this study, results ha...

In this study, ultrafine grained 2024 Al alloy based B4C particles reinforced composite was produced by mechanical milling and hot extrusion. Mechanical milling was used to synthesize the nanostructured Al2024 in attrition mill under argon atmosphere up to 50h. A similar process was used to produce Al2024-5%wt. B4C composite powder. To produce trimodal composites, milled powders were combined w...

Both test compression tools and ATPGs directly producing compressed test greatly benefit from don’t care values present in the test. Actually, presence of these don’t cares is essential for success of the compression. Contemporary ATPGs produce tests having more than 97% of don’t cares for large industrial circuits, thus high compression ratios can be expected. However, these don’t cares are pl...

Most of the recently discussed and commercially introduced test stimulus data compression techniques are based on low care bit densities found in typical scan test vectors. Data volume and test times are reduced primarily by compressing the don’t-care bit information. The original care bit density, hence, dominates the theoretical compression limits. Further compression can be achieved by focus...

Densification of oxide glasses at the glass transition offers a novel route to develop bulk glasses with tailored properties for emerging applications. Such densification can be achieved in the technologically relevant pressure regime of up to ~1 GPa. However, the present understanding of the composition–structure–property relationships governing these glasses is limited, with key questions, e....

Correlated data is a hot topic in many research fields. In fact, compression, detection, estimation, and transmission of correlated data arise in many practical applications, e.g., environmental monitoring, communication systems, image processing, etc. Identifying and properly managing such correlations may be important, especially when a very large amount of data, yet compressible, must be tra...
