Multi-scale Modeling and Constrained Sensitivity Analysis of Particulate CVD Systems

investigation of single-user and multi-user detection methods in mc-cdma systems and comparison of their performances

در این پایان نامه به بررسی روش های آشکارسازی در سیستم های mc-cdma می پردازیم. با توجه به ماهیت آشکارسازی در این سیستم ها، تکنیک های آشکارسازی را می توان به دو دسته ی اصلی تقسیم نمود: آشکارسازی سیگنال ارسالی یک کاربر مطلوب بدون در نظر گرفتن اطلاعاتی در مورد سایر کاربران تداخل کننده که از آن ها به عنوان آشکارساز های تک کاربره یاد می شود و همچنین آشکارسازی سیگنال ارسالی همه ی کاربران فعال موجود در...

Modeling and Sensitivity Analysis of Full Toroidal Continuously Variable Transmission

Modeling of Constrained Systems

The equations of motion for a mechanical system with nonholonomic velocity constraints are derived using the assumption that the generalized force vector must at each instant annihilate the space of all possible virtual displacements. We show how this assumption is in fact a consequence of more elementary axioms, such as Newton's second law (F = ma) for each particle of the system, or the equat...

Dynamic Harmonic Modeling and Analysis of VSC-HVDC Systems

Harmonics have become an important issue in modern power systems. The widespread penetration of non-linear loads to emerging power systems has turned power quality analysis into an important operation issue under both steady state and transient conditions. This paper employs a Dynamic Harmonic Domain (DHD) based framework for dynamic harmonic analysis of VSC-HVDC systems. These systems are wide...

Method for Multi-Scale Modeling and Simulation of Assembly Systems

This paper presents the on-going research steps aiming at the development of a Method for Multi-scale Modeling and Simulation of Assembly System. The focus lies on the Assembly System Base Model and its integration into the whole method. After motivating the research, the developed method and the conceived model of the assembly system is introduced, by using the proposed methodology. The presen...
