“…Parameters in the form of thermal efficiency and electrical efficiency must be considered in designing a thermal collector in a PVT system. 50% which indicates that this collector design can correct some of the deficiencies of the full cooler block design because the area of the thermal collector can be reached with the effectiveness of a more uniform working fluid [32].…”

Solar energy, harnessed from sunlight, can be efficiently converted and transmitted for various applications when coupled with photovoltaic cells and solar heat collectors. A photovoltaic thermal (PVT) collector not only aids in sustaining the power output of the photovoltaic module but also leverages a solar collector to generate heat, thereby facilitating cooling. The performance of PVT systems has been scrutinized by researchers through the implementation of diverse collector designs and fluids. Round and rectangular collector designs prevail as the most extensively utilized models. The materials adopted for collectors in the majority of PVT system evaluations are predominantly copper, with aluminum as an alternative. Several researchers have enhanced the performance of solar systems by integrating collectors with the addition of fins. This review examines numerous studies on PVT systems featuring optimal fins, aiming to concurrently augment both electrical and thermal efficiencies. Furthermore, this research intends to assess a variety of collector designs that have been employed in anticipation of performance improvements.

The application of waste rubber in the Civil Engineering is considered one of the most effective solutions for managing this waste. Therefore, the aim of this study is to analyze the effect of rubber substituted in cement on the physical and mechanical properties of concrete using the general full factorial design method, and compare the laboratory results with the results of the JMP pilot test program, and find out if there is a match between the results. The rubber powder is used as a mass substitute in cement at rates of 0%, 2%, 4%, 6% and 8%. The fresh properties were evaluated through workability, air content, and fresh density tests, whereas the hardened properties were assessed using tests of compressive strength, flexural strength, and ultrasonic pulse velocity. These concretes have the workability from 8 to 14.5 cm, fresh density from 2.20 to 2.38 (g/cm3). The air content ranged from 1.2 to 1.9%. Furthermore, the compressive strength ranged from 22.85 to 43.97 MPa, while the flexural strength ranged from 4.86 to 7.03 MPa. In addition, ultrasonic velocity from 3831.42 to 4098.36 (m/s). Accordingly, it was concluded that the concrete with 2% of rubber represented significantly better compressive strength compared to the ordinary concrete. The numerical modeling is assessed to have an appropriate determined coefficient R2 close to 1 for the workability, fresh density, air content, compressive strength, flexural strength, and ultrasonic pulse velocity.

“…Statistical study with factorial design approach (F.D.A): factorial designs allow estimating the efects of one factor at several levels of other factors, yield valid conclusions over a range of experimental conditions. It allows an optimum assessment of the main and interaction efects among the independent efect variables named factors "xi" and the outcome variables named responses "Y" [23].…”

The alkali-activated materials prepared by activation of glass powder (GP) and brick waste (BW) on the porosity and absorption of geopolymer paste by alkaline solution (alkali + water glass) were investigated. The effect of the combination of GP and BW on the porosity and absorption of the prepared geopolymer paste was monitored and evaluated by both laboratory and analytical methods. In this paper, three mortars were made with two sources of geopolymer containing 100% BW and 100% GP and blended with 90% GP and 10% BW replacements by mass. The compressive strength, porosity, and absorption of alkali-activated mortar were concurrently examined. Furthermore, the laboratory results obtained were estimated by the general full factorial design method. Finally, the analysis of variance was performed using the test results to analyze the importance of the effect factors and their interactions on the selected responses. The results concluded that mortar activated combined with 10% BW and 90% GP could be utilized in the industry of construction with minimum pollution problems and environment-friendly building materials, with the effect variables significantly affecting the responses.
