Abstract. Artificial pancreas is an alternative method instead of insulin treatment for patients with type 1 diabetes. Closed-loop control of blood glucose level (BGL) is one of the difficult problems in the field of biomedical engineering due to the dynamicity of time and the nonlinearity of the relationship between insulin and glucose, which is associated with time delay and model uncertainty. In this paper, we have proposed an integrated fuzzy-adaptive sliding mode control scheme for BGL tuning. Virtual patients described by mathematical models in MATLAB simulations have been used to evaluate the performance of the closed loop system in the presence of external disturbances, system time delay and patient-to-patient changes. System dynamics are determined online using fuzzy logic systems. The simulation results show the effective performance of the proposed control scheme of BGL regulation in the presence of simultaneous meals and physical movement disorders. The comparison of the proposed control method with the proportional-integral-derivative-derivative (PID) controller shows the superiority of the adaptive fuzzy integrated sliding mode controller with respect to the two common methods of BGL control and adjustment, namely PID and sliding mode. The results obtained by the control The proposer has demonstrated the effectiveness and robustness of the controller without the need for prior knowledge of T1DM patients. A remarkable feature of the closed-loop BGL regulator is that the controller can prevent hypoglycemia in patients with different physiological characteristics and adjust BGL to a normal level.

Biodiesel is a renewable and environmentally friendly liquid fuel. Due to problems such as not having sustainable sources, biodiesel production in commercial dimensions has problems. Vegetable oils are not a suitable source for biodiesel production due to their high cost and dependence on agricultural land. For this purpose, the use of insect oil as a new source for biodiesel production was investigated. In this research, the breeding of black soldier fly larvae with fruit waste as a source for biodiesel production was done. Then, biodiesel obtained from black soldier fly larvae oil was produced by transesterification method. At the end, a comparison between the characteristics of biodiesel produced in this research with other researches conducted in the literature was discussed. Viscosity of produced fuel was 4.83(mm2/s), density 878(kg/m3), cloud point +3(oC), pour point -3(oC) and flash point 134.2(oC).

Confining the concrete is a method of enhancing formability of structural reinforced concrete components. Fiber Reinforced Plastic (FRP) polymers are used to enhance seismic resistance and retrofit the existing structures. Therefore, assessment of the cyclic behavior of concrete components that are confined simultaneously by transversal steel reinforcements and FRP is of a significant importance. In the recent decades, a large number of helpful experimental studies have been performed on the effect of steel or FRP confinement, and different comprehensive analytical models have been proposed in this regard. However, less attention has been paid to the dual effect of FRB confinement and steel reinforcement on the cyclic behavior of the concrete. In this study, 32 concrete samples were tested under confining and cyclic axial stresses. The samples were confined by steel bars and/or CFRP with different reinforcement and enhancement scenarios. Afterward, the experiment results were used to assess the accuracy of a previously developed failure-based elastoplastic model. Additionally, few modifications were proposed in order to take the effects of concrete finish, longitudinal reinforcement, and continuous winding confinement as well as poor confinement effects into consideration. The modified model was used to forecast the behavior of the tested samples based on the experimental loading trails. The results complied with the experimental data showing that this model can simulate the cyclic behaviors of FRP confined and steel reinforced concretes precisely at the same time.

Among the lessons that students are weak on it and leads to a decline in their academic achievement is mathematics. Regarding the importance of this lesson, this study aimed to investigate the relationship between mathematics self-concept and mathematics anxiety with problem-solving ability in high school students. In this descriptive-analytic study 220 female high school students from Rasht city who were studying in the institutes of this city during the academic year of 2016-17 were randomly selected. In this study, statistical methods, mean, variance, standard deviation, correlation coefficients, Cronbach's alpha and factors analysis were used to analyze the collected data. Data analysis was done using computer software and SPSS. The used questionnaires were anxiety measure and self-concept measure, which includes the mathematics anxiety scale with the MARS-R questionnaire, the mathematics self-concept scale, and the written test of the math lesson at the end of the school year. The findings of the study indicate that mathematics anxiety has a significant effect on the variable of the problem-solving ability criteria in students, and anxiety reduces students' ability to solve problems. Also, the mathematics self-concept has a significant effect on the variable of the ability to solve problem in students and causes the improvement of the ability to solve the problem. In other words, the intensity of the relationship between the mathematics anxiety and the ability to solve the problem is reversal and -0.34, and the intensity of the relationship between the mathematics self-concept and the problem-solving ability in the students equals to 0.60 and is in direct form.

Nowadays, high-rise building construction and vertical development of cities is inevitable due to the increase in population and land prices. High-rise buildings indicate the advancement of technology and people's distance from untouched nature. Therefore, green architecture goes towards raising the quality of human life and building healthier buildings. Therefore, design is a progressive approach based on saving energy, paying attention to climatic issues and establishing a good relationship with nature, along with designing residential spaces with good quality and providing peace and comfort to its residents. In recent years, many efforts have been made regarding the use of renewable energies and it has become necessary and necessary to produce energy from them using advanced technology on a large scale due to the decreasing trend of fossil combustible materials in the earth. On the other hand, nowadays it is important how to use renewable energies in buildings, especially in architecture. Zero energy buildings are among these buildings with advanced technology. The architecture of the building should be designed based on the climatic conditions, and the potentials and limitations of the climate should be considered. Zero energy buildings pursue two goals: the first goal is to reduce the energy consumption of the building to the minimum possible, and the second goal is to produce energy in the building through renewable sources. This study is carried aimed to pay attention to the issue of building energy in the initial stages of architectural design in order to find the optimal form of a tall building in terms of receiving solar energy and determining the effective features in reducing the energy consumption of a tall building. What is important in this research is the reduction of energy consumption in the building by using passive solutions to reduce energy consumption with high economic justification and achieving a logical balance according to the definitions of zero energy, between the energy consumption of its production through renewable energy sources and power network. The method used in this study is descriptive-analytical.

Considering the importance of the ability to solve interpersonal problems in the formation of children's social skills, the purpose of this research is to investigate the effect of emotional regulation training based on the integrated human development model (DIR) on the social creativity of children with behavioral problems. And the boy was in preschool.

In order to achieve the goals of the research, a semi-experimental method and a pre-test, post-test and follow-up plan with a control group were used. The statistical population included 200 preschool children in Meybod city, among them 20 girls and 20 boys who had the lowest scores in Matson's social skills measurement scale; They were selected and randomly divided into two experimental and control groups. The experimental group underwent training based on developmental, individual differences, relationship- based model (DIR) in 10 two-hour sessions (two training sessions per week) and the control group did not receive any treatment during this period. The social creativity scale of Machirad and Lobart was used to collect data, which was completed before the intervention, after the end and 1 month later in the follow-up phase. The data were analyzed by multivariate and univariate covariance tests.

The results of the multivariate and univariate covariance test showed that emotional regulation training based on the integrated human development model (DIR) increased the social creativity of children with behavioral problems in both dimensions of originality and originality         (p < 0.05). ). Also, gender has not played a moderating role in this regard.

Emotional regulation training improved preschool children's social creativity and gender had no effect on this experimental relationship. Therefore, according to this finding, this educational method can be used to promote creativity in solving social problems for preschool children with behavioral problems.
