Abstract: New circuit solutions for alternative conditioning and refrigeration systems based on an open absorption cycle and direct regeneration of absorbent have been developed. The use of polymeric materials in the construction of the solar collector SK (a new type SK-P and the solar collector-regenerator SK-R) significantly (2.5 times) reduces its weight, cost (several times compared to domestic SK traditional designs), with the actual maintaining performance and reliability. Replacing glass with a polymer plate as a transparent coating increases its strength and significantly reduces the weight of SC, practically without leading to a decrease in the thermal characteristics of the product....

Abstract: This project aims to simplify the process of solving the anisotropic plate, with a specific emphasis on the sandwich plate with corrugated cores. The Integrated Thermal Protection System's in-plane extensional stiffness and out-of-plane bending and twisting stiffness are sandwich plates analyzed using a combination of classical laminate assumption, parallel axis theory of axis rotation, and structural smearing. The finite series assumption, classical laminate theory, and structural smearing are used to determine the bending and twisting moments of the Integrated Thermal Protection System, as well as its deflection. A computer program has been developed to handle the proposed model more.....

Abstract: Background: A physical risk factor, psychosocial risk factor and individual risk factors have shown a high prevalence of work-related musculoskeletal disorders among construction workers. The individual risk factors like age, gender, height, weight, BMI, types of work, duration of work, physical load and exertion and per day working hours are responsible for work-related musculoskeletal disorders. Materials and Methods: Total 465 manual construction workers participated in this study in which 414 male and 51 female. Out of 465, 385 workers responded that they have pain in different body parts, pain at different time zone from which 334 male and.....

Abstract: Fatigue testing is a material testing method that aims to evaluate how a material or structure reacts to cyclic loads or stress variations over time. The main goal of fatigue testing is to understand the behavior and resistance of materials to cyclic loads, which can cause the failure of materials or structures over long periods. Fatigue testing was carried out on AA 7075 material which has gone through a series of activities starting from turning the material according to ASTM in cylindrical shape, heating as solution treatment at a temperature of 475 0C for 5 hours.....

Abstract: In this paper we try to find the approximate solution of Exponential Forced Sine Gordon equation by the Modified Homotopy perturbation method. We formulate our equation by using the modified homotopy perturbation method so as to construct our homotopy equations, which can be solved by a normal integration. Then the summations of these solutions give us the final solution of our equation. We found our graphs solutions by using Mathematica computer programs which give us a positive and negative soliton solution.

Abstract: Based on the ideas of Industry 4.0, smart manufacturing is a revolutionary change in the manufacturing industry that will radically impact the way goods are created, manufactured, and distributed. The smooth incorporation of cutting-edge technologies into production procedures, which boost output and promote increased responsiveness to consumer preferences and market demands, is what defines this evolution. The incorporation of essential Industry 4.0 technology is at the core of this change.
