A predictive control based on neural network for proton exchange membrane fuel cell
, Article World Academy of Science, Engineering and Technology ; Volume 50 , 2011 , Pages 456-460 ; 2010376X (ISSN) ; Rezaei, M ; Najmi, V ; Sharif University of Technology

Abstract
The Proton Exchange Membrane Fuel Cell (PEMFC) control system has an important effect on operation of cell. Traditional controllers couldn't lead to acceptable responses because of time- change, long- hysteresis, uncertainty, strong- coupling and nonlinear characteristics of PEMFCs, so an intelligent or adaptive controller is needed. In this paper a neural network predictive controller have been designed to control the voltage of at the presence of fluctuations of temperature. The results of implementation of this designed NN Predictive controller on a dynamic electrochemical model of a small size 5 KW, PEM fuel cell have been simulated by MATLAB/SIMULINK
Lubricating flow of thixotropic fluids in slipper-pad bearing: A numerical study
, Article Nihon Reoroji Gakkaishi ; Volume 39, Issue 4 , 2011 , Pages 153-158 ; 03871533 (ISSN) ; Karimzadeh, M ; Sadeghy, K ; Sharif University of Technology

Abstract
Laminar, two-dimensional flow of an incompressible thixotropic fluid obeying Moore's model is investigated numerically in a slipper-pad bearing using FVM method. Results will be presented addressing the effect of thixotropic properties and inclination angle on the pressure distribution and load-carrying capacity of the bearing. It is shown that the pressure distribution under the upper pad depends only on the buildup-to-breakdown ratio. It is also predicted that by increasing this ratio, the load-carrying capacity increases, but, the pressure distribution becomes more and more asymmetric with the maximum pressure shifting towards the outlet section of the bearing. Also, for any given set of...

Abstract
Business intelligence (BI) is a managerial concept helping managers and organizations to manage information and make factual decisions. Some have introduced Business Intelligence as a process of turning data into information and then into knowledge. This concept has become a popular trend for businesses interested in adding value to their decision making processes. Measurement of maturity in implementing Business Intelligence process in organizations is considered a critical issue. Business intelligence like software development is a process, which expressed in terms of components such as artifacts and workflows. Capability Maturity Model Integrated (CMMI) is developed to define different...

Abstract
Despite the fact that a variety of analyses are conducted based on the performance of business excellence models according to organization type such as ownership, size and etc., the performance of organizations based on the factor of being routine or non-routine has not been investigated yet. In this paper, implementation of the European Foundation for Quality Management (EFQM) model for these types of organizations (routine and non-routine) has been examined. In order to do that, first we have developed a methodology to classify organizations into routine and non-routine categories. Then we have used discriminant analysis based on three factors, including process uncertainty, knowledge...

Abstract
The aim of this research is to design an implantable integrated microfluidic system in order to regularly measure the glucose level in the human body, nonenzymatically, using the microdialysis method. The main compartments of this system are a micropump, array of hollow microneedles and an electrochemical sensor. At the base of the microneedles, there are located semipermeable membranes, that when the pumped dialysis fluid passes over them, the glucose of the interstitial fluid diffuses into the dialysis fluid and then, in the sensor section, it is measured nonenzymatically using the amperometry method. Both the arrangement of the miconeedles and the amount of the dialysis fluid flow are...
Process integration of membrane reactor for steam methane reforming for hydrogen separation with CO2 capture in power production by natural gas combined cycle
, Article 9th International Conference on Greenhouse Gas Control Technologies, GHGT-9, Washington DC, 16 November 2008 through 20 November 2008 ; Volume 1, Issue 1 , 2009 , Pages 279-286 ; 18766102 (ISSN) ; Soltanieh, M ; US Department of Energy ; Sharif University of Technology

Abstract
In this paper simulation results for integration of CO2 pre-combustion capture by steam methane reforming (SMR) in membrane reactors (MR) with natural gas fired combined cycle (NGCC) power plants are presented. The integrated combined cycle was simulated by GTPRO (Thermoflow) simulator along with the results from simulation of membrane reactor for SMR process developed in this work. The results show that the overall efficiency of the integrated combined cycles decreased due to the energy required for SMR process. On the other hand, by integration of MR in combined cycles, emissions of CO2 to the atmosphere can be avoided. © 2009 Elsevier Ltd. All rights reserved

Abstract
The aim of this paper is to design and numerically simulate the mass-transfer compartment and piezoelectric micropump of an implantable integrated microfluidic device for regular microdialysis-based nonenzymatic measurement of glucose level in diabetic patients. The device function is based on the process that the piezoelectric micropump pumps the dialysis fluid into the mass-transfer compartment microchannels, where the interstitial fluid (ISF) glucose diffusion into this dialysis fluid gives it a glucose content, then detected and measured in the sensor section. This diffusion takes place through the semipermeable membranes located in the microchannels at the base of the hollow...

Abstract
Firms performance in their new product development (NPD) is believed to be positively related with involving suppliers in the process of new product development, and also with the organisations capacity and capability to absorb external and internal knowledge, namely absorptive capacity (AC). Addressing a gap in the literature, this study adopts the definition and structure for AC suggested by Tu et al. (2006) to examine relationships between ACs sub-dimensions with NPD performance, and also their moderating effects on the relationship between supplier involvement and new product development performance, on both financial and nonfinancial aspects. Data from a survey of 161 manufacturing...

Abstract
Diabetes is one of the most prevalent chronic diseases. Blood glucose control provides diabetics with the opportunity to keep their normal lifestyle, being a productive resource in the society, while ignoring to do so impose a huge cost to the society. Hence, it is of vital importance to find an appropriate approach to control and prevent the subsequent complications of diabetes. One of the most effective approaches is self monitoring of blood glucose (SMBG), which is now available through the commitment of a number of medical equipment companies to introduce SMBG products to the market. Some of the noted companies appointed Iran medical equipment market as a target for their market...

Minimising Conflict in Concurrent Channels: Solico Groups Case Study
, M.Sc. Thesis Sharif University of Technology ; Najmi, Manouchehr (Supervisor)
Abstract
Increasingly adopting of multiple channels by companies in order to achieve greater market coverage and more sale, has made managers to deal with a new challenge of avoiding conflict in multiple channels. The importance of the issue and lack of empirical research provided motivation to study approaches to minimize multiple channel conflict and explore how they reduce conflict. Therefore a qualitative study using a single case (Solico Group) was conducted. After reviewing the literature 7 approaches were identified to minimize multiple channel conflict: Superordinate goals (goals that achieving them requires efforts and resources of more than one channel), Brand (using products with different...

, M.Sc. Thesis Sharif University of Technology ; Najmi, Manoochehr (Supervisor)
Abstract
Based on symbolic theories BRANDS have personalities and according to this, brands like human beings have personality and stable behaviors in a period of time. Customers can imagine brands like a live creature according to different causes such as marketing communications, social responsibility of brand, CEO behaviors, clients, customers, etc. “BRAND PERSONALITY” is an interesting concept in world of marketing and it is one of the most important part of the brand identity. Brand personality makes people think at “brands” as friends. We consider “personality” as a perception of knowing, feelings and motivations that make people reactions toward their environment.
