The Global Minimizers and Vortex Solutions to a Ginzburg-landau Model of Superconducting Films

In this paper, we discuss the global minimizers of a free energy for the superconducting thin films placed in a magnetic field hex below the lower critical field Hc1 or between Hc1 and the upper critical field Hc2 . For hex is near but smaller than Hc1 , we prove that the global minimizer having no vortex is unique. For Hc1 << hex << Hc2 , we prove that the density of the vortices of the global...

با توجه به تحریم های بین المملی علیه صنعت بیمه ایران امکان استفاده از بازارهای بین المملی بیمه ای برای نفتکش های ایرانی وجود ندارد. از طرفی از آنجایی که یکی از نوآوری های اخیر استفاده از بازارهای مالی به منظور ریسک های فاجعه آمیز می باشد. از اینرو در این پایان نامه سعی شده است با استفاده از این نوآوری ها با طراحی اوراق اختیارات راهی نو جهت بیمه گردن نفت کش های ایرانی ارائه نمود. از آنجایی که بر...

Exact vortex solutions in an extended Skyrme-Faddeev model

We construct exact vortex solutions in 3 + 1 dimensions to a theory which is an extension, due to Gies, of the Skyrme-Faddeev model, and that is believed to describe some aspects of the low energy limit of the pure SU(2) Yang-Mills theory. The exact vortices appear in a very particular sector of the theory characterized by special values of the coupling constants, and by a constraint that leads...

An Effective Model for SMS Spam Detection Using Content-based Features and Averaged Neural Network

In recent years, there has been considerable interest among people to use short message service (SMS) as one of the essential and straightforward communications services on mobile devices. The increased popularity of this service also increased the number of mobile devices attacks such as SMS spam messages. SMS spam messages constitute a real problem to mobile subscribers; this worries telecomm...
