improvements in the properties of ordinary sidewall compound (nr/br) with the addition of epdm by reactive processing method were evaluated. the results show that ozone resistance of these sidewalls was improved with increased addition of epdm. also the tensile strength and elongation-at-break were increased in comparison with nrbrepdm compounds that were made by non-reactive processing. sem ph...

Title of dissertation: FLEX CRACKING AND TEMPERATUREHUMIDITY-BIAS EFFECTS ON RELIABILITY OF MULTILAYER CERAMIC CAPACITORS Mohammadreza Keimasi, Doctor of Philosophy, 2007 Dissertation directed by: Professor Michael Pecht Department of Mechanical Engineering Multilayer ceramic capacitors (MLCCs) are known to be susceptible to cracking when subjected to excessive printed circuit board (PCB) flexu...

A review of pavement thickness designs shows that two kinds of failure criteria are used in most cases. They are: 1) The tension strain under the asphalt layer that causes cracking and 2) the vertical compression strain on the sub-grade that causes deflection. In this study, various factors affecting thickness design are first defined and more than 216 pavement conditions are introduced. Struc...

Surface mount multilayer ceramic capacitors (MLCCs) are one of the most common components found on modern circuit card assemblies. Introduced in 1977, they are well known for their reliability and have been rapidly accepted by the electronics industry. The reliability of a nominal MLCC is extremely high, with expected operating lifetimes in the decades, if not hundreds of years. However, to att...

In recent decades, the application of fibre-reinforced polymer (FRP) composites for strengthening structural elements has become an efficient option to meet the increased cyclic loads or repair due to corrosion or fatigue cracking. Hence, the objective of this study is to explore the existing FRP reinforcing techniques to care for fatigue damaged structural steel elements. This study covers the...

In this paper we present new approach to lexical analysis in the Synt parser. We describe three fast lexical analyzers we have exploited for lexical analysis and advantages of the re2c fast lexical analyzer in comparison to others. This paper shows a new lexical analysis workflow which is both easy to maintain and portable to new languages. Finally we provide an evaluation of the new lexical an...

Focusing on the problems occurred in traditional 2D image-word-based web applications, the author put forward concept of integrating Web3D, Flex and SSH technologies to create advanced “3D Virtual Reality & RIA” web application architecture, researched mechanisms of their architectures, and implemented their integration and communication & interaction: Flex and Struts2 via XML, Flex and Spring ...
