یکی از پدیده های بسیار تاثیر گذار بر سرعت براده برداری و کیفیت نهایی سطح قطعه کار چتر می باشد که با اریه یک مدل مناسب از دینامیک سازه ماشین ابزار و نیروی چتر می توان شرایط ماشین کاری مناسب برای ماشین کاری بدون چتر را فراهم آورد در این پایان نامه تاثیر دینامیک ابزارگیر بر ابزار در نظر گرفته شده و اتصال ابزار با ابزاگیر با فنر عرضی و پیچشی با میرایی سازه ای مدل شده است با توجه به انکه طول ابزار ...

A direct immunosensor has been developed using an acoustic wave device as a transducer. The device is based on an acoustic waveguide geometry that supports a Love wave. The biorecognition surface, formed on a gold layer, consisted of a biotinylated supported lipid layer which specifically bound streptavidin and, subsequently, biotinylated goat IgG. The modified surface was used as a model immun...
On the basis of see-saw mechanism, possible generation structure is investigated. Assuming that right-handed neutrinos are realistic particles below GUTs mass, it is shown that there is a choice of new scheme of generation, where the combination of leptons and quarks is different from the ordinary one. Our scheme predict a new proton decay mode. 1 typeset using PTPTEX.sty §
I. Introduction During the past three decades, there has been a paradigm shift from import substitution strategies towards export‐oriented industrialization. It is in this context that countries saw the need to create special economic zones (SEZs) and export processing zones (EPZs), so‐called ecozones, to cope with the increasingly competitive environment of the global market.
We investigate the requirement of the existence of two degenerate vacua of the effective potential as a function of the Weinberg–Salam Higgs scalar field norm, as suggested by the multiple point principle, in an extension of the Standard Model including see–saw scale physics. Results are presented from an investigation of an extension of the Standard Model to the gauge symmetry group SU(3)C ×SU...
Two experiments demonstrate that 5-month-olds are sensitive to local redundancy in visual-temporal sequences. In Experiment 1, 20 infants saw 2 separate sequences of looming colored shapes that possessed the same elements but contrasting transitional probabilities. One sequence was random whereas the other was based on bigrams. Without any prior exposure, infants looked longer at the random seq...

We consider a TeV scale seesaw mechanism leading to light scalar resonances in models with otherwise intrinsically heavy scalars. The mechanism can provide a 125 GeV techni-color Higgs in e.g. two-scale TC models.
