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...

The purpose of this study was to investigate the effects of warm and cold physical as well as chemical processing methods on the nutritive value of barley grains by gas production technique. The processing methods included milling, steam flaking, extruding and soaking up the grain in water containing 1.00% citric acid, 1.00% propionic acid and 0.01 M sulfuric acid. Two-hundred mg of milling sam...

Although solidification cracking is not usually regarded as a serious problem when welding ferritic steels, improvements in the submerged arc welding process, using higher deposition rates and faster welding speeds, have led to welding conditions more likely to give cracking. Furthermore, the need to weld stronger tougher steels, where the inspection requirements are more stringent, has led to ...

The efficiency of Commercial FCC catalysts (low, medium and high activities) was evaluated by the catalytic cracking process of combined feeds of polypropylene (PP) and vaseline, using a microactivity test unit (M.A.T.) for the production of fuel fractions (gasoline, diesel and residue). The PP/vaseline loads, at 2.0% and 4.0% wt, were processed under refinery conditions (load/catalyst ratio an...

Password plays an important role in online authentication. But it suffer from two interactable problems ,one is password cracking and second is password theft. Password agent mechanism contains strong hashing scheme which provides stronger protection against password theft and password cracking. Password Agent generates strong passwords by enhancing the hash function with a large random salt. T...

A fractured nutcracker was examined for determining the root cause/s for premature fracture/failure. This is one of the common tools used typically for cracking hard nuts. In this study, metallurgical failure analysis techniques namely, visual inspection, optical microscopy, SEM, and hardness tests were used in investigating the broken product. From the metallurgical analysis, it was determined...

In the present work, the mechanical behavior of stress corrosion cracking phenomenon is described. Such phenomenon presents strong complexity due to metallurgic and electrochemical aspects. A methodology for modeling both SSR (Slow Strain Rate) and CL (Constant Load) tests based upon thermodynamics of continuum solids and elastoplastic damage is proposed. In this macroscopic approach, besides t...
