Computation of Quasi-Conformal Surface Maps Using Discrete Beltrami Flow
The manipulation of surface homeomorphisms is an important aspect in 3D modeling and surface processing. Every homeomorphic surface map can be considered as a quasiconformal map, with its local non-conformal distortion given by its Beltrami differential. As a generalization of conformal maps, quasiconformal maps are of great interest in mathematical study and real applications. Efficient and ac...
متن کاملPhysical Modelling of Self-Aeration in a Cavitating Sudden PIPE Expansion Flow
Sudden pipe expansions have been known as efficient hydraulic energy dissipaters for a long time. The complex phenomenon of flow separation and velocity discontinuity at the interface of incoming jet and the recirculation flow, results in intensive shear and tensile rupture of the fluid and the associated destructive phenomenon of cavitation. This paper focuses on aeration in sudden pipe expans...

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...
Free Energy Expansion in Quasi Stationary ROSt
In this paper we derive recursively an expression for the free energy of the Sherrington-Kirkpatrick (SK) model in the framework of Random Overlap Structures (ROSt) recently introduced by Aizenman and coworkers. This expression is obtained in the optimal Boltzmann ROSt via the infinite irreducible overlap correlation functions, which act globally as a sort of order parameter of the theory. In t...
متن کاملTurbulent flow through a plane sudden expansion
The results are reported of an experimental investigation of turbulent flow through a plane sudden expansion of expansion ratio R=D/d=4 and aspect ratio A= w/h=5.33. It is well known that plane sudden expansions with R greater than 1.5 produce asymmetric flows and this was again seen in this study. The literature for the asymmetric situation (R>1.5) is surprisingly limited and only axial veloci...
