چکیده: 

Purpose: The present study aims to identify and explain the futures of Iranian provinces in the competition for the development of NBIC technological CONVERGENCE (synergy between nanotechnology, biotechnology, information technology and cognitive sciences) with a focus on Yazd province. Method: This research, which has been conducted with a qualitative and descriptive approach, is classified as an exploratory futures-study. In this way, the relevant research records were first reviewed to compile a list of drivers in the development of convergent technologies. The list was then refined and prioritized to identify two key drivers, with the Delphi process attended by fourteen experts. By intersecting the uncertainties of these two drivers, four scenarios of the province's future in technological CONVERGENCE competition emerged. Findings: The two key drivers affecting the success of the province in the competition for convergent technologies are: the rate of development of the innovation ecosystem and the amount of financial resources allocated to this process. Based on this, four scenarios of the future situation of the province in this field were identified, which have been named as "Vanguard", "Buyer", "Remnant" and "Hired". Conclusion: In ORDER for the provinces to be able to succeed in the forthcoming competitions in the production and operation of convergent technologies, it is necessary to plan for strengthening the ecosystem infrastructure from now; at the same time, it is necessary to make efficient efforts to provide sufficient financial resources for the research and commercialization of these technologies.

چکیده: 

IN THIS STUDY, A NEW MODIFIED FIFTH-ORDER HARDY-CROSS METHODS IS PRESENTED FOR WATER DISTRIBUTION SYSTEMS. IN THE STEADY-STATE CONDITION, THE GOVERNING EQUATIONS OF WATER NETWORKS ARE THE CONTINUITY EQUATIONS FOR EACH NODE AND THE ENERGY EQUATIONS FOR EACH LOOP. THE FORMER EQUATIONS ARE LINEAR IN RESPECT TO FLOW RATE WHILE THE LATTER ARE NONLINEAR ALGEBRAIC ONES. THEREFORE, THE TRUE MEANING OF SOLVING A PIPE NETWORK IS TO SOLVE A SYSTEM OF NONLINEAR ALGEBRAIC EQUATIONS IN TERMS OF PIPE FLOW RATES. ON THE CONTRARY, THE HARDY-CROSS METHOD, AS ONE OF THE HYDRAULIC-SOLVER APPROACHES, SOLVES PIPE NETWORKS WITHOUT BUILDING THE AFOREMENTIONED SYSTEM OF EQUATIONS, WHICH IS SUPPOSED TO BE MORE EFFICIENT THAN THE MATRIX-BASED ONES. ALTHOUGH THE ORIGINAL HARDY-CROSS METHOD DOES NOT PROVIDE A MATRIX-BASED SCHEME, IT PERFORMS MUCH LESS EFFICIENT IN COMPARISON WITH THE OTHER MATRIX-BASED APPROACHES. THE HARDY-CROSS METHOD UTILIZES A SPECIFIC KIND OF INITIAL GUESS WHICH SATISFIES THE CONTINUITY EQUATIONS IN ADVANCE OF DEALING WITH THE ENERGY EQUATIONS, WHICH ARE INDIVIDUALLY SOLVED FOR EACH LOOP. HENCE, ONE OF THE MAJOR CHALLENGES OF THIS APPROACH IS ITS LOW RATE OF CONVERGENCE. THE PROPOSED MODIFIED HARDY-CROSS METHODS GRASP HIGHER ORDER OF CONVERGENCE THAN THE ORIGINAL APPROACH. FINALLY, THE COMPARISON OF THE PROPOSED FIFTH-ORDER HARDY-CROSS METHODS WITH THE ORIGINAL ONE CLEARLY DEMONSTRATES THAT THE RECOMMENDED MODIFICATION IMPROVES THE RATE OF CONVERGENCE OF THE ORIGINAL HARDY-CROSS METHOD.

چکیده: 

In this paper, a new smooth second ORDER sliding mode control is proposed. This algorithm is a modified form of Super Twisting algorithm. The Super Twisting guarantees the asymptotic stability, but the finite time stability of proposed method is proved with introducing a new particular Lyapunov function. The Proposed algorithm which is able to control nonlinear systems with matched structured uncertainty, is able to guarantee the finite time stability. The main advantage of this second ORDER sliding mode control is reaching to sliding surface with high precision without chattering in control signal. In simulation section, the proposed algorithm is compared with the boundary layer sliding mode control and then is applied to designing a finite time nonlinear guidance law that is robust with respect to target maneuvers. Simulation results show that the control input in this algorithm is smooth and has no chattering and by applying this method, sliding variables will converge to zero in a given desired finite time.

چکیده: 

In this paper, following a very recent and new approach, we further generalize recently introduced summability methods, namely, I-statistical CONVERGENCE and I-lacunary statistical CONVERGENCE (which extend the important summability methods, statistical CONVERGENCE and lacunary statistical CONVERGENCE using ideals of N) and introduce the notions of I-statistical CONVERGENCE of ORDER a and I-lacunary statistical CONVERGENCE of ORDER a, where 0<a<1. We mainly investigate their relationship and also make some observations about these classes and in the way try to give an answer to an open problem posed By Das, Savas and Ghosal in 2011. The study leaves a lot of interesting open problems.

چکیده: 

Modification of Newtons method with higher-ORDER CONVERGENCE is presented. The modification of Newtons method is based on Frontinis three-ORDER method. The new method requires two-step per iteration. Analysis of CONVERGENCE demonstrates that the ORDER of CONVERGENCE is 6. Some numerical examples illustrate that the algorithm is more efficient and performs better than classical Newtons method and other methods.

چکیده: 

Sluggish Cognitive Tempo is used to describe a particular type of attention deficit, concentration, and slowness in information processing. The aim of this study was to investigate the psychometric properties of the Sluggish Cognitive Tempo Scale (SCTS) of the parent form among Iranian children. The present study is a descriptive study. A sample of 1700 people was selected from the provinces of Tehran, East Azerbaijan, West Azerbaijan, Kurdistan, Fars and Khorasan using cluster sampling method. 122 subjects were excluded from statistical analysis due to incomplete answers to the questionnaires and thus the final sample was reduced to 1578 parents. The confirmatory factor analysis method and internal consistency were used to compute the Sluggish Cognitive Tempo Scale factorial validity and reliability, respectively. Also, in ORDER to examine the construct validity of the Sluggish Cognitive Tempo Scale, we computed correlations between different dimensions of Sluggish Cognitive Tempo Scale with Attention Deficit Subscale of Mental Health Assessment Questionnaire for Children and Adolescents. The results of statistical results showed that this scale has structural validity, criterion and CONVERGENCE in Iranian society. The results indicate that the scale is three factors and also the validity of the scale using Cronbach's alpha method and retest test after Approved two weeks. According to the findings of the present study, the parent form of the Sluggish Cognitive Tempo Scale (SCTS) has a good validity and reliability and it can be used in research related to slow cognitive multiplication in Iranian society.

چکیده: 

Resistance is one of the fundamental Quranic values in the cause of the development of the Islamic society and the formation of the Islamic civilization, which means standing and resisting against something has upset the balance in internal and external dimensions. The formation of this value in the society as one of the methods of the conventional model of human life in the fields of human life; So that its manifestation can be observed in the totality of social behaviors, it is called the culture of resistance (Problem statement). The purpose of this article is the achievement of the engineering process of this value in a society based on the growth-oriented thought (ideological) system of the Holy Quran (Purpose). Now the question is what process does the Holy Quran propose in ORDER to engineer the culture of resistance in the society? (Question). The necessity of examining this issue is clear considering the emphasis of religious teachings on this value and the need for Islamic societies, especially considering the current conditions of Islam and the need for CONVERGENCE and coordination between the resistance front (Necessity). The research method in stating the engineering process and its components is qualitative content analysis with an analogy approach (Method). The findings of the research show that the engineering process of resistance culture is based on a self-awareness and purposefulness, according to the idea of Quranic growth, in a three-stage process that leads to the happiness of man and human society (Conclusion).
