The purpose of this paper was to study existing and desirable status of social educations in secondary school. This was descriptive survey and statistical population included all teachers in secondary schools in Orumiyeh. Survey methodology was census conduction. Structured questionnaire on properties of social educations curriculum in secondary schools was applied in order to study teachers’ v...
Requirements engineers not only have to cope with the requirements of various stakeholders for complex software systems, they also have to consider several software qualities (e.g., performance, maintainability, security, and privacy) that the system-to-be shall address. In such a situation, it is challenging for requirements engineers to develop a complete and coherent set of requirements for ...
The reliability of distribution networks is inherently low due to their radial nature, consequently distribution companies (DisCos) usually seek to improve the system reliability indices with the minimum possible investment cost. This can be known as system-oriented reliability planning (SORP). However, there can exist some customers that are not satisfied by their reliability determined by ado...
in this paper, based on the background of cost-oriented assembly line balancing problems, a novel mathematical model for scheduling and balancing the assembly line is offered that with the combination of task sequence-dependent setup time, parallel stations and resource constraint, minimizes the operational and investment costs of assembly system. due to the complexity of the problem, the equat...
Assembly lines are flow-oriented production systems that are of great importance in the industrial production of standard, high-volume products and even more recently, they have become commonplace in producing low-volume custom products. The main goal of designers of these lines is to increase the efficiency of the system and therefore, the assembly line balancing to achieve an optimal system i...
political evolutions and struggles of 19th century prepared the ground for realization of nationalities and emergence of nationalist movements. the realization of national identity in countries such as iran, turkey and egypt was partly due to the emphasis of governments on glorious history or ancient modernity of these nations. emergence of nationalism in any country is affected by political, ...
The problem-oriented approach is one of the efficient methods of “contemplation in Quran”. This approach is applied as opposed to the subject-oriented and concept-oriented approaches. Historical analysis of the commentators’ appeal to the verse 97 Surah An-Nahl shows that lack of having the problem-oriented approach has led to the fact that many of them ignored this verse without making any com...
To develop an efficient robotic system is always a challenge, in particular if the cost of the system is also an important factor. This paper presents an overview of development of our 10 degree of freedom humanoid, Betty. Reducing the cost of the system requires optimization of all aspects to retain its flexibility, reliability and performance at minimum cost. During the design and development...
this paper studies the effects of the structural variables of the iranian industries sector on the welfare cost using to the structure-conduct-performance (scp) theory. in other words, we investigate the role of structural components and their effects on the size of the welfare cost in iran's industry sector. we have used the leibenstein's model to calculate the deadweight loss and then the pan...
