In this study, the numerical modeling of sediment washing in Sefidrood dam reservoir and its effect on reservoir volume recovery in the short and long term have been studied. For this purpose, the GSTARS 3 numerical model has been used to study the different phases of flashing. This model is prepared for free and pressurized sedimentation and each of them is analyzed separately. Studies on Sefidrood Dam show that due to the fact that the reservoir water level at the beginning of the flashing operation is one of the influential parameters in the efficiency of sediment washing efficiency, lowering the reservoir water level from normal (271 m) to the power plant (210) M) Reduces the water consumption from 897 cubic meters to 19 cubic meters for washing each ton of sediment. On the other hand, studies show that flashing does not affect coarse-grained sediments in this reservoir and cannot be used as the only solution to prevent reservoir depletion, and additional sedimentation operations such as dredging, use of siphons or In addition to annual sedimentation in the Sefidrud Dam reservoir, it is inevitable that heavy currents will flow through the reservoir.Send

Education at all levels plays a very important role in achieving sustainable development. The main goals of education are to raise the level of knowledge, analysis and ethics in individuals and increase their sense of responsibility towards society. Chapter 36 of Workbook 21, entitled "Education Development and Raising Awareness," addresses the importance and role of education in sustainable development. Engineer training in the 21st century should be in line with the goals of sustainable development so that it can play a role in correcting the attitude of young engineers and applying these principles in their lives and specialized activities. One of the important tasks of universities is to provide a suitable platform for such education. In this regard, Amirkabir University of Technology, as one of the most important industrial universities in the country, is developing various strategies in this field. Establishment and strengthening of postgraduate courses in environmental engineering, presentation of new courses related to various fields of environment and sustainable development for all engineering students, change and modification of course topics and establishment of environmental research institute are among the most important of these strategies. As an example, a course called "Green Design" is envisaged in the curriculum in which students become familiar with the basics and principles of green attitude in design. Changing the attitude of engineering students from traditional design to green design (where the principles of sustainable development are considered by the designer) is one of the main goals of this course. The purpose of this paper is to examine the role and tasks of 21st century engineers and to explain the basic strategies of Amirkabir University of Technology in line with the goals of the Green University and sustainable development.

Proper training of hydrologists in the field of precipitation-runoff modeling can play a significant role in overcoming many flood problems. In this paper, after introducing the liquid analog model, it is established as a new analog model in the field of hydrology and based on the linear reservoir model. Its scale and laboratory construction are presented, and then how it is used to simulate the Nash precipitation model for a real basin. The effect of basin shape on the output hydrograph as well as the effect of precipitation direction on basin response has been investigated separately. The results of the experiments performed with the model indicate that the model is suitable in this field. Due to the simple structure, ease of use and visual quality of the model, this model can be a suitable teaching aid tool in the field of precipitation-runoff modeling training.

The presence of a number of compounds such as silicon oxide and titanium in bauxite is considered to be one of the most important factors in reducing the quality and poor quality of refractory products. In this study, the possibility of recovering and extracting these compounds and increasing the Al2O3 / SiO2 modulus in Shahid Nilchian boxing mine in Chaharmahal and Bakhtiari province has been investigated using reverse flotation method. In this study, among the factors affecting the flotation process, three factors of pH, type and amount of collector and arrester have been selected and studied. Talc alkaline amine has been used as a collector and tannic acid as a deterrent and dispersant. Using this method, the amount of titanium compounds and Al2O3 / SiO2 module has been significantly reduced and increased, respectively. Among the three factors studied, pH is the most effective factor in the effectiveness of bauxite flotation.

To schedule a project, you need to pay attention to the uncertainty about some of the project's parameters, such as the cost and time of the project. Fuzzy theory is used to consider this uncertainty. This article gives you a brief overview on project scheduling and how it works. To prepare this type of scheduling program, first, according to the amount of available resources and the normal time of activities, various possible scheduling programs are prepared. The project completion time and cost are calculated for each schedule. If neither of the scheduled schedules can meet both goals, better timing plans will be provided by changing the timing of activities and the amount of resources available. In the end, among all the scheduling programs, the one that has the best conditions according to the importance of each of the two criteria of cost and time is selected. PRIMAVERA software has been used to prepare the initial scheduling program and C ++ programming language has been used to prepare the mentioned search algorithm. The above algorithm has been used to schedule a real bridge construction project and good results have been obtained.Send

Previous research has shown that there is a significant relationship between managers' knowledge and performance. In the present study, it is assumed that there is a significant correlation between computer knowledge of managers, experts and faculty members with their efficiency. The statistical population and the sample group consist of managers, experts and faculty members of Science and Technology Park (36 people). The Computer Science Questionnaire (Seven Skills) was validated by 82% of Cronbach's alpha methodologists. Employee evaluation form was used to measure efficiency. The results showed that among the seven skills related to computer knowledge, there was a relationship between the three skills of presenting content by computer, spreadsheets and word processors with efficiency. Accordingly, it is necessary to emphasize the strengthening of these skills in the in-service training of employees.

The present article is about the need to pay attention to teaching sustainable architecture in Iran and examining its facilities and obstacles. The aim of this training is to gain scientific knowledge about environmental resources, ethical principles, values and skills in line with the goals of sustainable development and people's participation in decision-making. In the transition from conventional architecture to a sustainable architecture series, architectural education requires a fundamental transformation and also faces numerous and structural obstacles. Problems with educational planning in sustainable architecture include the use of environmental resources, transportation, building materials, the collection and integration of building systems, and multi-purpose uses that are consistent with human values. In Iran, these trainings are in conflict with the habits of society and require the coordination of the management structure. The study of sustainable architecture education in three Iranian universities has shown that despite some shortcomings in this education, students' attitudes have been oriented and sufficient motivation has been created to change performance. The solar architecture, which became popular in the 1970s after the energy crisis, has been hailed by many masters in Iran as part of its curriculum.Send
