Published: March 2020

Abstract
This paper presented the effect of using multiple sources of photovoltaic (PV) cells and battery on the input dc link channel of voltage source converter (VSC) for distribution STATCOM (DSTATCOM). The first high coordinated design is applied on the input of three-leg VSC for DSTATCOM to provide a continuous voltage over the time without delaying or interruption in the power through the control circuit and Dc to Dc circuit for boost of photovoltaic cell and buck-boost of battery. When there is a large of sun radiation, the generating power of PV is supplied to the three-leg VSC of DSTATCOM for power demand compensation and the surplus power is saved at the battery. In the condition of night or cloudy days the battery is discharged to maintain the sustainability of the VSC DSTATCOM. In addition, the design is used a Star / Delta transformer to isolate three-leg VSC for DSTATCOM to provide a circular path for zero sequence fundamental and then reducing harmonics the neutral current. The purpose of using DSTATCOM is to reduce the harmonics of current source, compensate the reactive currents and compensate the ground currents in the point of common coupled (PCC). The type of algorithm that used to coordinate the compensation process of DSTATCOM is a synchronous reference frame (SRF).

First phase consists pre-processing methods in which selected image is handled using color to gray scale image conversion and histogram equalization. Result image of which is manipulated by standard Viola-Jones algorithm to detect and crop face area from the whole image. While to ensure same size for all images, detected face image is resized to 256 × 256. Second phase tends to extract LBP features to be fed in the next classification phase. In third phase, two classifiers Logistic Model Tree (LMT) as well as Sequential Minimal Optimization (SMO) have been applied on the extracted features for age estimation.

Abstract
An Arduino microcontroller has been used for many projects since its first presentation in 2005. This integrated chip used with a variety of sensors to construct many attractive projects and circuits. In this paper, we aim to investigate the resolution ability of one of the famous sensors attached to the Arduino which is called the ultrasonic HC-SR04 sensor. This sensor basically, is made from a transmitter and receiver that work in the sonar range of frequencies. It is used to indicate the distance of objects similar to the Radar principle. By experimental results another feature could be added to the data sheet of this sensor, named as distance resolution. By applying a reasonable shape and dimension for the target objects at a distance of 11 cm, the experimental results show that this sensor has resolution ability configured in the range of 7 cm displacement between two adjacent objects. Furthermore, the paper suggests increasing the sensor aperture to increase such ability for certain application that used the sensor for discrimination between adjacent objects.

Abstract
This paper presents the design and analysis of optical fiber biological sensor to measure and monitor the glucose ratio in blood samples. Simulations are carried out using Optisystem software to determine the optical power and mode for each sample. The sensing was accomplished by design Mach-Zehnder interferometer with using multimode fibers. The cladding of these fibers is stripped out of the fiber part. In addition, the wavelength of the light source has to be absorbable by the glucose in order to be detected. As a result, the refractive index (RI) of different serum glucose level has increased linearly by increasing the serum glucose level while the parameters of the RI step and the output power decreased linearly by increasing the RI of different serum glucose level. This result can be concluded as a new method for serum glucose level assessment.

Authors: Hamzah Mahmood Mohammed , Hussein Sabah Khammass 
Published: March 2020

Abstract
Hot press bounding technique was used to join a polyethylene sheet of 4mm thickness to stainless steel AISI 304L of 1mm thickness. Three different process parameters were used during the joining process: pressure of 4, 6, 8 and 10 bar, processing time of 1.5, 2, 2.5 and 3 min. and temperature of 115, 120, 125 and 130°C. The steel surface was treated with two methods: mechanical (scratch) and electrochemical (electro-polishing) treatment. A shear tensile, microstructure, scanning electron microscope and energy dispersive spectrometry tests were used to examine the joint specimens. The effect of process parameters on the joint properties was analyzed by the Minitab program. The scratched and electro-polished joint specimens exhibited a maximum shear force of 1112 and 1022N respectively. The tested joints were failed by an interfacial shear and necking in the polymer side with a ductile fracture. The joining process was occurred by a mechanical interlocking between the molten polymer and pores of the treated surface of steel specimen. The average thickness of the joining line for the scratched and electro-polished specimens was 5 and 4μm.

Published: March 2020

Abstract
Similar aluminum alloys (AA5086-H32 with AA5086-H32) were welded by friction stir welding (FSW) using three different values of linear speeds; namely 50, 75 and 90 mm/min.and different and rotating speed namely 680, 920 and 1500 rpm. Tensile test was used to determine the joint efficiency of welded samples. The microstructure, hardness, tensile tests and fatigue properties were studied for the welded sample which gave the highest tensile strength. The fatigue test was carried out at a constant stress amplitude cantilever fully reversed( R=-1) in the stir zone of weld and nearby zone or region at a distance of 5, 10 and 15 mm from the welding line. The fracture fatigue surface was analyzed using SEM. It was found that the maximum joint efficiency of 80% was obtained at rotating speed of 680 RPM and linear speed of 75 mm/min. The maximum value of hardness was at the stir zone center of the weld and started to decrease away from it. Fatigue strength of the FSW welded samples was less than the parent or base alloy.

Abstract
Experimental Modal Analysis (EMA) is very helpful in engineering design and manufacturing of machine components. In this paper, modal parameters which are natural frequencies, mode shapes and damping ratios are extracted for free-free boundary conditions circular shaft, using EMA, then two disks are added to this shaft as second case study. EMA has been verified as effective and accurate tool, despite of increasing geometrical complexity and nonlinear behaviour of the structure. The two well-known excitation techniques (i.e. impact hammer and shaker) are used for this purpose. For validation, natural frequencies and mode shapes are determined analytically and numerically by Finite Element Modelling (FEM) ANSYS 15 workbench software, and then compared with results obtained experimentally. Noticeable remarks about these approaches are listed. Coherence plots are compared between impact and shaker tests. Digital Signal Processing (DSP) settings like windows type and sample (record) time are compared. The recommended DSP settings mentioned in this work can be used as a general guidance for researchers and people who are working in modal analysis.

Abstract
This paper focuses on assembly line balancing (ALB) problem which the objective is to maximize the assembly line efficiency. The problem solved using a greedy heuristic method. MATLAB Software is used to perform the proposed greedy heuristic method. Then, the proposed method is applied to a previous real life case problem that is found in literature for the cookers assembly line in the Light Industrial Company in Iraq. The results of the proposed method is compared with the performance of the company without applying any assembly line balancing method. The result of this paper is also compared with the results obtained from a previous work in the literature which is based on Shortest Operation Time (SOT) using the software named Quantitative Methods, Production and Operations Management (POM-QM). The outcomes of the research have shown that the greedy heuristic method is more efficient, where the efficiency increased from 78.24% before applying assembly line balancing and 81.64% for the previous work based on SOT method to 85.53% when applying the greedy heuristic method. The research has recommended that the decision maker in the company should follow the most appropriate method to achieve a high efficiency operations.
