The first stage of the RTM process concerns the preforming of the part. During the preforming of multilayered reinforcements, frictions between the plies occur. An experimental device designed to analyse the ply/ply, ply/tool and yarn/yarn frictions has been set up. Specific contact behaviour for ply/ply friction is directly related to shocks taking place between overhanging yarns of each sampl...
The current study focussed on analysing natural frequency and damping of laminated composite beams (LCBs) by varying fiber angle, aspect ratio, material property boundary conditions. Ritz method with displacement field based the shear normal deformable theory is used modal calculated using strain energy method. Effects symmetric angle-ply cross-ply, anti balanced quasi-isotropic lay up schemes ...
• In-situ monitoring of transverse cracks and delamination for CFRP laminates under fatigue. Poisson’s ratio identifies whether early fatigue damage involves delamination. Interactive levels between are quantified. Correlation cumulative acoustic emission energy crack density. Ply-block size stress level effect on accumulation investigated during life laminates. Tension-tension tests different ...
Aggressive treatment with antibiotics in patients infected with Streptococcus pneumoniae induces release of the bacterial virulence factor pneumolysin (PLY). Days after lungs are sterile, this pore-forming toxin can still induce pulmonary permeability edema in patients, characterized by alveolar/capillary barrier dysfunction and impaired alveolar liquid clearance (ALC). ALC is mainly regulated ...
Pore-forming proteins are weapons often used by bacterial pathogens to breach the membrane barrier of target cells. Despite their critical role in infection important structural aspects of the mechanism of how these proteins assemble into pores remain unknown. Streptococcus pneumoniae is the world's leading cause of pneumonia, meningitis, bacteremia and otitis media. Pneumolysin (PLY) is a majo...
در این مقاله، حل دقیق ارتعاش آزاد برای بررسی تأثیر تورق بر روی فرکانسهای طبیعی تیرکامپوزیتی نسبتا ضخیم توسط سادهسازیهایی صورت گرفته است. تئوری مورد استفاده تئوری تیموشنکو میباشد که برای شرایط مرزی مختلف ارائه شده است. در فرمولبندی ارتعاش تیر، اثر اینرسی دورانی، تغییر شکل برشی جانبی و اثر پوآسون در نظر گرفته شده است. در بررسی تورق، هر دو مود آزاد و مقید بررسی شدهاند. تأثیر اندازه و موقعیت...
We investigate the problem of inferring, from records of chess games, some aspects of the strategy used to play the games. Initially, game records are generated from self-play by two simple chess programs, one of which does a one-ply search while the other does a four-ply quies-cent search. In each case, we are able to infer, from just the game records, good estimates of the weights used in the...
