Abstract:
The work reported on is an extension of work done in Washington State to examine the systematic occurrence and variability in pavement mat density. The focus will be on the extent of the pavement that is affected by variable density due to temperature differentials and the fact that randomly based testing does not identify the occurrence of cyclic density differentials. Temperature differentials 14°C (25°F) or greater generally cannot be compacted to the same level of density as the surrounding mat and therefore lead to significant density differentials (increase in air voids of 2% or more).

Abstract:
Abstract Preclinical hemolysis testing is a critical requirement toward demonstrating device safety for U.S. Food and Drug Administration (FDA) 510(k) approval of mechanical circulatory support devices (MCSD). FDA and ASTM (formerly known as the American Society for Testing and Materials) have published guidelines to assist industry with developing study protocols. However, there can be significant variability in experimental procedures, study design, and reporting of data that makes comparison of test and predicate devices a challenge. To overcome these limitations, we present a hemolysis tes

Because of time urgent before putting into operation and different place line protection equipment located, joint debugging for extra high voltage (EHV) transmission line is often not perfect although EHV transmission line is very important for modern grid.

To overcome the shortages of static fault simulation commonly used, which cannot accurately simulate fault characteristics in runtime, a synchronous joint debugging device is designed based on based on the analysis of the jo

The operating principles, as well as the technical aspects of the implementation of a new computer-controlled pressure standard are presented. The instrument can have dual use: either as a pressure source or as a pressure sensor. The device is intended mostly for use in problems where small differential pressures are of interest, i. e., 0–2.5 KPa and high accuracy is desired. Such a pressure range encompasses, for example, most of the pressure measurement applications in subsonic wind-tunnel testing.
