Operating temperature has been considered a major factor that affects solar panel efficiency. The efficiency of the solar panel is influenced either by increasing or decreasing the panel temperature. The aim of this paper is to design a cooling system to improve the efficiency of the solar system by reducing the temperature of the panel. In this design, additional waterproof layer is added under the button of solar panel to provide more protection from any water leakage, then a region filled wit...

This paper proposed a semi-analytical solution for evaluation of field distributions around the surface of a ferromagnetic metallic half space, which contains a hidden long crack and excited by a three-dimensional arbitrary frequency current-carrying inducer. The solution was obtained by using the method of separation of variables in three dimensions. This research assumed that the conductor as a lossy dielectric and used the concept of a rectangular waveguide, which is partially loaded with die...
This paper presents an analytical approach to model linear and nonlinear mass and heat transport with space and time varying parameters. The approach gives a possibility to predict mass and heat transport in multilayer structures without crosslinking the solution on interfaces between layers in these structures. Based on the approach, we analyzed the possibility to increase the density of field-effect heterotransistors in an enhanced swing differential Colpitts oscillator. The results indicate t...
This work aims to investigate signal to interference plus noise ratio of femtocells for indoor users under long term evolution (LTE). Ethiopia has different cities with big buildings, companies, hotels, hospitals, condos, residential houses, and others. Signal attenuators like several walls, number of floors, and others affect the quality of the signal. For this reason, femtocells are taken as a solution to enhance the signal quality. This work considers signal to interference plus noise ratio w...

With the accelerated advancement in technology infrastructure, the concept of libraries in the educational institution has evolved from a traditional system, which consists of several manual processes requiring human intervention to perform critical tasks, to that of a smart library system where the core activities are automated through the use of Internet of Things (IoT) devices. Integrating IoT devices in the different processes enables the streamlining of such processes rendering them more ef...
In this paper, a new optimization technique called SSA-SA approach has been suggested. This proposed technique, which is the hybridization of two meta-heuristic techniques named Salp Swarm Algorithm (SSA) and Simulated Annealing (SA) method aims to improve the global optimal solution of ED problem in electrical power systems, considering the various complexities of practical operational constraints, such as valve point effects, active transmission losses, Prohibited Operating Zones (POZ) and Ram...
An invariant to rotation watermarking approach is proposed for the purpose of improving the security of digital images. The proposed digital watermark approach is invariable to rotation and guarantees the integrity of the inserted mark. The size of the resulting image is identical to the original image and the process guarantees acceptable transparency. This approach evolves both in the frequency and the spatial domain. Specifically, the proposed scheme processes the JPEG images by adapting its ...

Wireless LAN (WLAN) technology is becoming increasingly popular as an option to provide wireless internet access in corporate, campus, residential, public space, and others. Wireless Mesh Network (WMN), as one of the innovations of WLAN technology offers a unique solution as it can effectively and efficiently replace or enrich the capabilities of both the existing wired and wireless-based internet network infrastructure. This is because it can cover wider and difficult to reach service areas wit...

The ability of the aircraft to trace the waypoint trajectory is a major requirement for the completion of various missions. However, the magnitude of steady state error and multiple overshoot caused by environmental disturbances can cause instable motion of the aircraft. Such conditions can make the aircraft experience a shift and change its direction from a predetermined path. Therefore, in this study Linear Quadratic Regulator (LQR) control method is applied to minimize steady state error and ...

In this paper, a high frequency ring-VCO using an improved differential delay-cell (DD-cell) is presented. The proposed DD-cell benefits from a bandwidth extension technique. Facilitated by the wide band cell, the oscillation frequency of the proposed VCO can be increased up to 15.45 GHz. The DD-cell has tunable loads, which is used to change the operating frequency of the proposed VCO between 6-15.45 GHz. The proposed VCO has been designed and simulated in CMOS 65nm process with 1V supply volta...
