The original definition of a topological space given by Hausdorff used neighborhood systems. Lattice-valued maps appear in this context when you identify a topology with a monoid in the Kleisli category of the filter monad on SET. H?hle’s notion of a lattice-valued topology [2] uses the same idea and it’s inspired in the classical lattice-valued topologies. Ltopological spaces are motivated by ...

مدل روزنه های موازی موج دار (corrugated oarallel bundle model) برای تعریف اثر ساختمان روزنه ها در نفوذ-واکنش (diffusion and reaction) در کاتالیستهای متخلخل بکار می رود. در مدل روزنه های موج دار، از یک دسته روزنه های اصلی (pore) استفاده شده است . هر یک از این روزنه های اصلی دارای یکسری عناصر روزنه می باشد که هر عنصر دارای یک شعاع تعیین شده به صورت اتفاقی از یک توزیع اندازه روزنه ها (pore size di...

Uniform deposition of nanofibers in the massive electrospinning process is critical in the industrial applications of nanofibers. Tip-Induced Electrospinning (TIE) is a cost-effective large-scale nanofiber-manufacturing method, but it has poor deposition uniformity. An auxiliary conductive electrode connected to the emitting electrode was introduced to improve the deposition uniformity of the n...

Background & Objective: Radiotherapy has a very special significance in the treatment of cancer. Beam radiation therapy using photons and electrons produced by a linear accelerator is used extensively in the treatment of breast Cancer. In this article, In addition to providing a description of three techniques of radiotherapy in the treatment of breast cancer, has been Evaluating the effectiven...

This paper proposes a method to solve multi-objective problems using improved Particle Swarm Optimization. We propose leader particles which guide other particles inside the problem domain. Two techniques are suggested for selection and deletion of such particles to improve the optimal solutions. The first one is based on the mean of the m optimal particles and the second one is based on appoin...

Introduction: In this work, we attempted to correct the non-uniformities generated in lower limbs (calf and thigh) NMRI by RF inhomogeneities. Correction techniques are based in general on prior knowledge about the intensity distribution inside tissues (or tissue magnetic properties) which is not straightforward in case of pathological muscles, as in neuro-muscular disorders. For our applicatio...

Objective: Calcium imaging is an essential tool for obtaining neuroactivities to understand the complex function of brain. The one-photon miniscope, most widely used endoscope in neuroscience, employed record neuronal calcium activities vivo. However, current half ball lens overlooks energy dis...
