Clock gating is an effective way to decrease dissipated power in synchronous design. The most effective way to do this is by masking the clock that turns toward the unused part of design. In this paper, a comparative evaluation of power consumption in existing clock gating techniques in Arithmetic Logical Unit (ALU) design was achieved. an innovative signal clock gating method offers extra immunity in the direction of the present issue in an accessible mechanism. A Gated Clock Generation designs using a tri-state connection and logic gate, generated by the set of bubbled input with NAND gate, is used for the latest suggested clock gating. This design saves power even when the clock is at applying to the target module. Complete power analysis reveals that the proposed technique has an effect on the dynamic power that decreases total power consumption up to 24.90% relative to traditional power. All experiments are done in arithmetic logic unit design. 130 nm standard logic libraries have been used for implementation in order to achieve ALU frameworks. The ALU design architecture was developed using the Verilog HDL, and the simulations are performed utilizing ModelSim-Altera 10.0c (Quartus II 11.1) Starter Version.

“…Solar energy is a very large, inexhaustible source of energy, moreover, using solar energy instead of fossil fuels reduces CO2 emissions and thus reduces global warming [1]. Solar energy can be transformed into electricity by a solar photovoltaic panel or to thermal energy by a solar collector to use for many purposes [2][3][4][5][6][7][8][9].…”

This study presents a solution to the selection of the optimum orientation for non-tracking solar photovoltaic panels and non-tracking solar thermal collectors with a new methodology in Baghdad city. The optimum tilt angle of solar application was determined monthly, seasonal and yearly based on the largest monthly average daily total solar radiation incident on the surface in Baghdad. The solar radiation and tilt angle were calculated theoretically with the help of MATLAB R2016b and the theoretical data of solar radiation were validated via comparison with experimental data. The optimum tilt angle results of months have been ranging as follows: from 3.77˚ for June to 62.88˚ for December, moreover the optimum tilt angle results for the seasons and year have been as follows: 60.41˚, 38.88˚, 5.26˚, 31.34˚ and 33.97˚ for winter, spring, summer, autumn and annual respectively, and best directing the fixed solar applications toward the south. The results were compared with previous studies and showed an increase in monthly average daily total solar radiation for all months except for April and September.

“…In nanofluid, the metal or metal oxide particles having a diameter less than 100 nm mix with water to get maximum performance from solar collectors. However, only using water as an operative fluid in solar collectors leads to lower thermal efficiency (Kadhim & Ibrahim, 2021). Further, this efficiency can be increased by modification in design which again costs more (Shafieian et al, 2019).…”

The research article investigates the thermal performance of heat pipe-based evacuated tube solar collector (ETSC) experimentally using graphene oxide (GO) and deionised (DI) water as working fluid with a mass flow rate of 0.5 lit/min, 0.75 lit/min, and 1 lit/min. The different volumetric concentrations of 0.001%, 0.002%, and 0.003% graphene oxide nanofluid samples were prepared in the deionised water. The X-ray diffraction (XRD) was used to determine the structural properties of graphene oxide and the morphology of graphene oxide was studied by scanning electron microscope (SEM). To evaluate the stability of nanofluid samples, the Zeta potential analysis was carried out which showed that prepared nanofluid samples remain stable for up to 30 days. The effect of different nanofluid concentrations on various thermo physical properties of nanofluid was studied and discussed. The thermal performance of ETSC was investigated by considering the effect of volumetric concentrations of nanofluid and mass flow rates. According to the findings, there is a significant increment in temperature difference and energy gain by using nanofluid samples, and the maximum thermal efficiency of ETSC was found to be 37.1% for a volumetric concentration of 0.003% at 1 lit/min mass flow rate as compared to water.
