An Oligopoly Model for Studying Equilibrum Strategy of Seasonal Goods Dynamic Pricing in Competitive Market with Demand Uncertainty
, M.Sc. Thesis Sharif University of Technology ; Kianfar, Farhad (Supervisor)
Abstract
This paper studies sub game perfect Nash equilibrium of a price competition in an oligopoly market with perishable assets. Sellers each has one unit of a good that cannot be replenished, and they compete in setting prices to sell their good over a finite sales horizon. Buyers each demand one unit of the good in each period and the number of buyers coming to the market in each period is random. All sellers’ prices are accessible for buyers, and search is costless. Using stochastic dynamic programming methods, the best response of sellers can be obtained from a one-shot price competition game regarding remained periods and the current-time demand structure. Assuming a binary demand model, we...
Flow Simulation to Assess Effects of Various Parameters on Performance of a Gas Ultrasonic Flowmeter
, M.Sc. Thesis Sharif University of Technology ; Mazaheri, Karim (Supervisor)
Abstract
In this thesis we are going to improve an ultrasonic flowmeter accuracy by considering the influence of different parameters like temperature, pressure, etc. Firstl of all different cases of flow condition in which ultrasonic flowmeter may work are specified, then velocity and temperature profile of pipe flow are determined using Fluent software. In thr next step ultrasonic pulses transmitted are simulated by the use of code written in Matlab to find wave travel time in the flow. Evetually an accurate relation of calibration for flowmeter is determined by the use of travel time and all other flow properties to evaluate the accuracy of flowmeter in diffent cases. Relation extracted can be...

Abstract
Due to the expansion of web applications, they have been gradually enhanced as to their usage of information and services. As a result, web users are faced with growing complexity, which has raised concerns not only on the quality and validity of information, but also on how the information is presented. This has resulted in the advent of a new branch of web systems called adaptive web systems, which focus on the adaptation of content, presentation and navigation based on the properties of the runtime environment and the preferences of the users. Generally, the concept of adaptivity can be appeared in the fields of non-functional services and requirements. Although this research is only...
Mapping activity diagram to Petri Net: Application of Markov theory for analyzing non-functional parameters

Abstract
The quality of an architectural design of a software system has a great influence on achieving non-functional requirements of a system. A regular software development project is often influenced by non-functional factors such as the customers' expectations about the performance and reliability of the software as well as the reduction of underlying risks. The evaluation of non- functional parameters of a software system at the early stages of design and its development process are often considered as major factors in dealing with these issues. Because these evaluations can help us to choose the most proper model which is the securest and the most reliable.In this paper, a method is presented...
