This paper contains a theoretical formulation of multiple interface cracks in two bonded dissimilar half planes subjected to in-plane traction. The distributed dislocation technique is used to construct integral equations for a dissimilar mediums weakened by several interface cracks. These equations are of Cauchy singular type at the location of dislocation, which are solved numerically to obta...

primary and widely in use computed tomography (ct) dose descriptor is a volumetric ct dose index (ctdiv) that is usually measured by a pencil ionization chamber with active length of 100mm and polymethyl methacrylate (pmma) phantom. ctdiv depends on scan parameters such as mas, kv, collimation, tube rotation time but is independent of patient’s size and shape. for the purpose of a good estimati...

in the present research, damage mechanisms during room temperature uniaxial tensile testing of two different modern high strength dual phase steels,dp780 and dp980, were studied. detailed microstructural characterization of the strained and sectioned samples was performed by scanning electron microscopy (sem). the results revealed that interface decohesion, especially at the triple junctions of...

1. Introduction HCI research and design practice has long recognized that interactive systems are useless if they do not support users in performing their work tasks. To this end, the representation and modeling of users' task knowledge is a major concern. In particular, a key concern is how to make informed design decisions based upon that knowledge and how to predict the effects of design sol...

In [Perry 85] we reported work in progress on the analysis of software interface faults in a large software system. In this update of that work, we complete the analysis of the interface faults for this large system and extend our results. In our original analysis, we determined that there were 15 categories of interface faults in the prima facie interface fault set of errors reports. We add on...

-Sudoku puzzles appear in many forms of digital and physical media. In fact, millions of people around the world know how to play Sudoku. All the same, the skill behind this game is a lot more complex than it seems. That is why many researchers have set a notable measure of exertion to generate efficient algorithms to figure out these puzzles. Some researchers might even propose that an algorit...

abstract: a time domain semi-analytical solution to study thermoelastic creep behavior of  functionally graded rotating axisymmetric disks with variable thickness is presented. the rate type governing differential equations for the considered structure are derived and analytically solved. to solve these  equations, the disk is divided into some virtual sub-domains. general solution of  equilibr...

despite the great potential of graphene as a nanofiller, achieving homogeneous dispersion remains the key challenge for effectively reinforcing polyolefin (such as polyethylene (pe) and polypropylene (pp)) nanocomposites. therefore, in this research, we report a facile combined in situ polymerization and masterbatch method for fabricating pp/reduced graphene oxide (rgo) nanocomposites. in the p...

most of the materials used in the industry of aero-engine components generally consist of titaniumalloys. advanced materials, because of their excellent combination of high specific strength, lightweight and general corrosion resistance. in fact, chemical wear resistance of aero-engine alloyprovides a serious challenge for cutting tool material during the machining process. the reductionin cutt...

purpose:the user interface of federated search engines is very important because it can make effective search, retrieval, and user interaction with the system. . identifying the most important indicators of the federated search engine user interface is a solution to enhance the applicability of the search engine interface. the purpose of this study was to examine the role of search, screen, nav...
