Single-Point Diamond Turning (SPDT) has been widely used in manufacturing of optical components for critical applications including military, defense, aerospace, computer science, electronics, medical, and dental. Magnetic Field (MF) assistance is a recent non-conventional assistive technique that could be used during SPDT process to improve the machining conditions. Recent experimental studies show that using MF […]
To fabricate ultra-fine grain structures containing high strength, accumulative roll bonding is a kind of severe plastic deformation (SPD). In the present study, magnetic Al/ Fe2O3 composites reinforced with 0, 2.5% and 5Wt.% of Fe2O3 particles have been manufactured via ARB. A uniform distribution of Iron oxide particles was achieved after the 8th cycles of […]
In this article, a multiple input multiple output quadrate frequency bands modified PIFA antenna is introduced for 4G LTE and WLAN applications. The quadrate proposed antenna covers LTE 1800 (1.71-1.88 GHz), LTE 1900 (1.85-1.99 GHz), UMTS (1.92-2.17 GHz), LTE 2300 (2.305-2.400 GHz), LTE 2500(2.50-2.69 GHz), WLAN (2.400-2.484 GHz- 5.15-5.75 GHz) specified by IEEE 802.11a/b/g/n/ac and […]
In this study, the combination of Gray Wolf Optimization and Artificial neural networks (GWO-ANN) algorithm was applied to predict the long-term electricity demand in Iraq, considering the nonlinear trend and uncertainties in the variables affecting it. The results indicate that the population and gross domestic product are significant explanatory variables for long-term energy demand, consistent […]
Solar energy serves as one of the promising resources of renewable energy due to its abundance availability and clean nature. Climatic data such as irradiation level and temperature are essential as input variables while designing the photovoltaic-based system. This research paper presents an extensive comparative analysis of modeling approaches of photovoltaic modules using a 1-diode […]
A Harmonic Control Circuit (HCC) is one of the most important blocks in the Class-F power amplifiers, which should pass the even harmonics and suppress the odd harmonics. Long open stubs are usually used to suppress odd harmonics in the conventional Class-F power amplifiers, which resulted in the large size of the amplifiers. In this […]
A multidimensional approach to technology breakthroughs, including innovations in sensors, artificial intelligence and cloud technology, is driving automation. In past few years, people have started for using electronic machines more frequently than traditional ones. As a result, this study suggests a technique wherein moisture sensors are positioned beneath plants or trees. The microcontroller activates the […]
Fuel shortages and environmental issues have made optimal and effective management of various resources one of the most pressing issues in the current situation. There is often a separation between the heating and gas network and the power system, which is not wise when considering the economics and effectiveness of the entire system. Examining the […]
An Internet of Things-based security system and OpenCV technology have been developed to improve the efficiency and ease of monitoring video footage from CCTV. The face detection process is carried out using the Haar Cascade method, while facial recognition is carried out using the Local Binary Pattern Histogram algorithm. The test results show that light […]
The addition of renewable energy sources to the traditional distribution network has transformed the centralized unidirectional power source into two-way and multiple power source system. This will improve overall system’s reliability and also reduces the down time that are associated within the radial distribution system. This paper investigates the impact of distributed energy sources like […]
