Estimating a Mixed Profile MDCEV:Case of Daily Activity Type and Duration

, M.Sc. Thesis Sharif University of Technology Shamshiripour, Ali (Author) ; Samimi, Amir (Supervisor)

Abstract

The closed-form formulation of MDCEV has become popular in past years, as it accounts for satiation effects through a novel consumption-based utility structure. The model, however, suffers from an “empirical identification” problem. The problem is mainly due to entangled roles of two model parameters in capturing satiation effects. Thus far, the best known solution to the problem is fixing either or both of the parameters to pre-defined values and estimate a restricted satiation profile. This paper, presents a new hybrid optimization algorithm (named HEMPME) to eliminate the need for imposing such restrictions, and disentangle the two effects through estimating a “mixed profile” model....

Numerical Study on the Influence of Magnetic and Electric Fields on Filtration Performance of Wet Granular Beds

, M.Sc. Thesis Sharif University of Technology Sabbaghian, Sina (Author) ; Moosavi, Ali (Supervisor) ; Sadrhosseini, Hani (Supervisor)

Abstract

The aim of this study is to develop an understanding of the role of the magnetic and electric forces on the filtration performance of wet granular beds. At first, the effect of wetting is considered by locating micro water film around the square channel for particles deposition in four different Reynolds Re=1 to Re=10 number, Typically 1000 particles in different sizes (100nm-10μm) were injected to microchannel when air and water formed completely on the surface of the block. The Drag force, Brownian force, Saffman`s lift force and the gravity force are affecting the particles. After that Dielectrophoretic and Magnetophoretic forces were included in the domain for investigating the role of...

Design, Development, and Test of a Magnetic Nano Monowing

, M.Sc. Thesis Sharif University of Technology Saffizadeh, Amir Reza (Author) ; Banazadeh, Afshin (Supervisor)

Abstract

In the present study, an attempt has been made to design and develop a nano drone using the dynamics of single-wing drones. To reduce the noise associated with nano-drone motors, a unique magnetic system has been developed for the drone's propulsion system, which has technology similar to magnetic trains and uses the theory of magnetic suspension, which is one of the main innovations of this dissertation. The drone designed in this research will have a blade with a radius of 15 cm and its total weight will be 170 grams, which according to the thrust of the blade will be able to carry a load of 50 grams for 14 minutes. In this research, after the initial design of the drone and related...
