Identifying the Ethical Dilemmas Confronting Human Resource Managers of Iranian Project Based Companies and Exploring their Causes

, M.Sc. Thesis Sharif University of Technology Shokatian, Taha (Author) ; Alavi, Babak (Supervisor)

Abstract

The present study was performed aiming to identify the ethical dilemmas human resource managers confront with in Iranian project-based organizations as well as to trace out the underlying causes. “Ethical dilemma” refers to a decision making situation in which ethical considerations render all the alternatives inapt, thence making the decision making process ethically complex. First of all, a theoretical framework was developed based on the preceding research; then, the study was further conducted utilizing a qualitative research method with an exploratory approach. The data were collected using in-depth interviews and analysed using the theme analysis method. The corresponding interviewees...

Transfer Alignment Algorithm Development for Aerial Launch Space Launch Vehicle Navigation System Using the Carrying Airplane Navigation System

, M.Sc. Thesis Sharif University of Technology Shokatian, Mohammad (Author) ; Fathi, Mohsen (Supervisor)

Abstract

In this research the problem is the development and simulation of Transfer Alignment algorithm for an aerial launch space launch vehicle. In the references there is no complete study on development of this algorithm for the case space launch vehicle. In order to develop the algorithm, the carrying airplane and the space launch navigation systems are considered as the Master INS and Slave INS respectively. First a 6DOF simulation of the airplane is presented. Then the desired inputs for simulation of Master and Slave INS are generated. Also the differences of the inputs of Slave INS caused by the distance between the Master and Slave INS is considered. Master INS performs as an ideal INS and...

Exploring trends in the codes of ethics of the Fortune 100 and Global 100 corporations

Abstract

Purpose: The purpose of this paper is to explore emerging trends in the content of codes of ethics of US Fortune 100 and Global 100 corporate web sites through a longitudinal study. Design/methodology/approach: The web sites of the 200 companies were surfed and the relevant documents of the codes of ethics were extracted to separate text files. The computer files were then mined using the customized developed software and each ethical keyword was counted. The number of filed codes of ethics was 95 for both the 100 US-based and the 100 Global-based companies. Findings: In addition to the content analysis of the ethic codes of the studied groups and finding high-frequency ethical keywords, the...

Study the Books of Science and Physics Education in Iran from the Perspective of Current Philosophy of Science

, M.Sc. Thesis Sharif University of Technology Nayyerhoda, Taha Reza (Author) ; Golshani, Mahdi (Supervisor)

Abstract

In this research, I intend to case study formal education textbook in Iran that responsible for educate science in elementary school or educate physics in high school that to study the situation of education in this field of knowledge in Iran. The method of this research is study the text of textbook and find instance that somehow build philosophy of science assumption in students’ minds. In the following, I categorize these founded phrase that find in all related books, following the current philosophy of science theories. In the end of this research, I present an explanation of these authors textbook’s assumption

Deformation Analysis of Magnetic Elastomers using Finite Element Method

, M.Sc. Thesis Sharif University of Technology Norouzi, Faezeh (Author) ; Naghdabadi, Reza (Supervisor) ; Sohrabpour, Saeed (Supervisor) ; Goudarzi, Taha (Co-Advisor)

Abstract

Magnetic elastomers are smart materials that consist of a combination of elastomeric matrix and magnetic particles. The mechanical and magnetic properties of this materials are changed by Applying an external magnetic field. The presence of an external magnetic field can cause these elastomers deform largely.Significant deformations of the magnetic elastomers, has made them suitable for a wide range of applications. The aim of this project is to solve the governing equations of magnetic elastomers with finite element method. Since there are no suitable models for the behavior of these elastomers in the commercial softwares, magnetic field module and solid mechanics module should be coupled...

Studying the Wisdom of Crowd Through Large-Scale Experiment & Statistical Simulations

, M.Sc. Thesis Sharif University of Technology Nasiri Garabolagh, Mahdi (Author) ; Ejtehadi, Mohammad Reza (Supervisor) ; Yaseri, Taha (Co-Supervisor)

Abstract

In this thesis, we have tried to study one of the most well known collective behavior phenomena known as the Wisdom of the crowd, from the perspective of statistical physics. In recent decades with the appearance of Social Networks and mass media, collective social phenomena have become a critical topic in the life of every human being. In the Wisdom of crowd phenomenon, the overall process is to ask the crowd’s opinion regarding a special topic and after aggregating the predicted values, the aggregated quantity is declared as the wisdom of the crowd. It has been observed that in some polls and elections, the result of the wisdom of crowd outperforms every individual of the group and in some...

Multiscale Multiphysics Analysis of Deformable Microwave Metasurfaces Under Large Deformations and Prototype Fabrication

, Ph.D. Dissertation Sharif University of Technology Karimi Mahabadi, Rayehe (Author) ; Naghdabadi, Reza (Supervisor) ; Sohrabpour, Saeed (Supervisor) ; Goudarzi, Taha (Co-Supervisor)

Abstract

Electromagnetic metamaterials are designed artificial materials with sub-wavelength resonant inclusions. They can exhibit extraordinary properties such as negative permittivity, negative permeability, and anomalous reflection/refraction. Metasurfaces are 2D counterparts of metamaterials. Here, we proposed a framework for the multiscale multiphysics analysis of deformable metasurfaces. Nonlinear mechanical analysis (Geometry and material behavior), periodic boundary conditions, homogenization, multiscale analysis, and electromagnetic analysis are implemented in this framework. Benefiting from the framework, we proposed a multifunctional hyperelastic structured surface that can generate...

Modeling of Fischer-Tropsch Synthesis Reactor for GTL Process

, M.Sc. Thesis Sharif University of Technology Al Taha Motahar, Narges Khatoon (Author) ; Khorasheh, Farhad (Supervisor) ; Taghikhani, Vahid (Supervisor)

Abstract

There is a need from the natural gas and energy industries to seek for an economically attractive way of converting remote gas reserves into transportable products, such as high quality fuels or petrochemicals. A possible way for the conversion of natural gas to middle distillates is based on a three-step process. Firstly, production of syngas from natural gas. Secondly,catalytic conversion of syngas into hydrocarbons, mostly parafins from C5 to C100. (Fischer-Tropsch (F-T) synthesis). Thirdly, hydrocracking of the heavy paraffinic hydrocarbons to middle distillates. The F-T synthesis step is highly exothermic. In order to control the temperature within the reactor, when considering high...
