In this project, we examine the stability or sustainability issue in unions, in other words we want to know whether integration in European Union is stable? Countries have positive attitude toward unions and being member in unions is at special priorities. The main reason for countires is improve economy and national Security.
The main question in this research is modeling European Union with Axiomatic Design Theory and analysis of sustainability based on this theory. This study has attempted to push Axiomatic Design Theroy in the new field of Systems Engineering and also it gives a new and differnet approach to stability.
 

Modeling and simulating accurate patterns which are adapted to our real world is a hard and complicated task. The most important thing for these models is finding any explicite solution, or, finding any solution that is precise as much as possible. The knowledge of financial mathematics by gathering several sciences such as: probabilities, stochastic analysis, numerical analysis, and stochastic differential equations, attempt to determine such exact solutions, or, try to appoximate the explicit answers as precise as possible; in the world of financial trades and contracts. Moreover; one of the most important requirements to control the risk of these financial cotracts, and, then to optimize... 

Communications is considered as a large part of project managers’ activities. Communications is one of success factors in the projects. A project manager in addition to have a good sight on project knowledge areas needs to know how to use them in order to reach a suitable point with integrating them by using communications. A survey on communications can predispose lots of dissertations in this field & subsequently causes improvement & continues development.
In this thesis, different areas of project body of knowledge have been explained & effect of communication on them has been described. In next step, this study depicts how to manage communications in projects & project-oriented... 

MAPNA is a leading project oriented company in the field of power, water, oil and transportation in Iran. MAPNA has the policy of using quality management principles and tools to improve the company and in this regard has chosen EFQM excellence model as a tool to move towards excellence. EFQM requires a set of indicators to measure performances of the processes and their results. These indicators should be tailor made for the company.
The subject of this thesis is to evaluate the present indicators used in implementing EFQM in MAPNA and considering MAPNA’s characteristics propose any changes required. The study is limited to indicators for key results and customer results for certain... 

Productivity is the effective usage of input or resources for production or output. Input (including Energy, raw materials, capital and work force), which is being used for output (including final products or services performed by an organization). Productivity, increases gross domestic product and competitiveness, and improves level of living. Firms and related management levels play the main role in improving productivity. Using productivity cycle management brings the productivity to improve as a permanent process, specifies the rout for productivity and prepares the ground. The most important step in productivity cycle (PDCA) is the measurement of productivity. In this research several... 

We search for supersymmetry in the same-sign dilepton final state in the first 35 pb1 of data collected by the CMS detector and find no evidence of new physics at this point. Since true same-sign physics backgrounds, such asWWjj, are negligible for this amount of integrated luminosity, we focus our attention on data-driven estimations of the backgrounds where one (W+jets and tt backgrounds) or both of the leptons (QCD background) are fake. We use the generalized fake ratio method documented to estimate the rates for these fake backgrounds. Another source of backgrounds in the case of electrons is the charge-flip, where the charge of one of the electrons in an opposite-sign di-electron pair... 

Jets originating from bottom (b) quarks, play an important role in the study of Standard Model processes together with the search for new physics. In the CMS experiment a considerable e?ort is dedicated to the development and the performance study of so-called b-tagging algorithms. On the other hand, the top quark which is produced in pair (tt¯) with a high rate at the LHC, decays near 99% of the time to a b-quark. Hence it provides a rich source of b-quark jets, suitable for b-jet identi?cation studies. In this thesis, a fully data-driven method to measure the b-tagging e?ciency, using top quark events in its semi-electron ?nal state, is developed. The results of the application of the...
