  • Effect of Ultraviolet Radiation and Alpha-particles on Nuclear Track
           Detector CR-39

    • Abstract: In this work, the bulk etch rate VB is calculated using various methods, including the removed thickness, the saturation track, and the length-diameter track. A 200 μm-thick CR-39 detector manufactured by Page Moldings (Pershore) in the United Kingdom was cut into several identical pieces (1x1 cm2). In order to obtain longitudinal track profiles, these sheets were exposed to alpha particles with an energy of 2.6 MeV emitted from a 241Am source, followed by 30 minutes of exposure to UV light. The CR-39 samples were etched in a 6.25 N NaOH solution at 70 C. These tracks are etched for 15 minutes before being digitally photographed with an optical microscope. It was established that the predominant lengths of alpha particle tracks are those that fall perpendicular to the detector surface. The bulk etch rates for CR-9 were found to be 1.227 μm/h for irradiation with alpha, and 2.035 μm/h for irradiation with UV and then alpha particles.

  • Calculating the Electrons Distribution Function for Gallium Arsenide at
           Low Fields by Solving ...

    • Abstract: The electron distribution function for gallium arsenide GaAs was calculated by using the Boltzmann transition equation in the central valley , for a range of low fields relative to the threshold field (E0 = 5.95Kv/cm) (0.3-1)E0. To obtain the distribution function, the Boltzmann transport equation was solved using a mechanism that combines the analytical and numerical methods. Analytical method involving extension of the Legendre polynomial was used and the effect of polar optical scattering was introduced as the dominant scattering mechanism in this research, as well as the effect of an asymmetric energy band structure with spherical energy surfaces in the central valley. After obtaining a partial differential equation of the second order, it is solved numerically after separation process for the variables using the direct matrix method in energy space by building a mathematical program using MATLAB. In this study, a system with dimensions of 360 × 360 was built, and the rate of change in energy was taken as 0.001.The computational system was tested by applying low electric fields, and the distribution function that was obtained had a Maxwellian distribution at very low fields, and it shifted from the Maxwellian distribution at higher fields close to the threshold field, and the results obtained were agree with previous results. While this system did not give accurate results at the high-electric fields.

  • Evaluating the Electro Magnetic Fields Radiation of the Cell Sites and
           Their Environmental ...

    • Abstract: Cell phones, also known as mobile or portable phones, have become an essential part of contemporary communication technologies. In some regions of the world, they are even the only available means of communication, as they are so well-liked for allowing people to communicate with one another without having any impact on their movements. Cell phones are becoming increasingly popular, with more than 50% of people in some nations owning one. The industrial community anticipates that by the year 2030, there will be more than 8 billion users worldwide. To accommodate broadcast and reception, more cell phone stations (towers) are being built. These stations, which are radio antennas, work to protect connections with cellular telephone equipment while using minimum power. The goal of this proposed study is to measure the electromagnetic fields radiated by cell phone towers and their effects on the local environment in a selected area of Mosul, Iraq. The results will then be compared to international standards, evaluated to help develop methods for protecting people's health, and solutions to the issue will be offered.

  • EFFECT OF THE EXCITED VOLTAGE RISE TIME ON THE CORONA DISCHARGE
           CHARACTERISTICS

    • Abstract: In this paper, the rise time of the exciting voltage on the DC corona discharge characteristics in a coaxial electrode system is presented. The current one-dimensional simulation study focused on the distribution of the plasma species (ions and electrons as well as the excited atoms) during two different times of the applied voltage climb was classified as a fast rise time (615 ns) and a slow rise time (2710 ns). The growth time of the corona excited voltage was controlled by the external feed RC circuit that connected with the central electrode. The simulation results reveal that the corona inception which occurs at a fast rise time produces more dense plasma charged species, while the density of the excited atoms is not much affected by the applied voltage climb time. The density of excited atoms tends to depend on the rise time of the exciting voltage at the steady state.

  • Producing Interpenetrating Network from Waste Tires Rubber with commercial
           Unsaturated Polyester

    • Abstract: Waste tires constitute environmental problems because of their three-dimensional complicated structure. The presence of different additives within their composition makes them difficult to degrade. In this research, the waste tire rubber is used as raw material after inserting effective groups, like the carboxylic group within the rubber to be used directly without the need to separate additives or recover the rubber individually. Ground tire rubber (GTR) was modified by functionalizing with different ratios of maleic anhydride. Network polyester was prepared from modified GDR and diethylene glycol. Interpenetrating networks IPNs were prepared from polyester of GTR with trade unsaturated polyester. The characterization of the IPNs was studied via infrared spectroscopy, thermal analysis, X-ray diffraction analysis, and AFM pictures. The results indicate that there is a complete interaction between the two types of networks and the IPNs are of one phase. Also increasing the MAn ratio in the GTR gives more homogeneity to the produced IPNs, whereby the number of crosslinking increases.

  • Optimal Parameters for Spatial Distribution Modeling of Global Horizontal
           Solar Radiation in Iraq

    • Abstract: Abstract Solar radiation plays an essential role in all interior physical processes and the radiative budget of the earth-atmosphere system. However, information about the spatial distribution of global solar radiation or its components is limited and exclusive at some scientific centers that specialized in solar radiation physics. Based on daily data of global solar radiation from (1984) to (2004) available at (16) locations in Iraq retrieved from NASA e-archive, this study aims to determine the optimal parameters of the experimental model to estimate the amount of global solar radiation on a horizontal surface as a function of latitude only. The results showed that the suggested model which is mathematically expressed by the sum of sine of latitude is highly appropriate for estimation of global solar radiation in clear sky conditions after adjusting the parameters according to geographical location. Through comparison between modeled output and an independent measured, globally used, and satellite available data and based on overall results besides some validity metrics: MBE, RMSE, pRMSD, NSE, R2, and r; It can be concluded the proposed model is achievable with high accurate practically performance to calculate and estimate the horizontal global solar radiation (GH) in Iraq region.

  • Evaluation of the best Edge Filters in Image Processing Based on the Color
           Fabric Texture

    • Abstract: With the development and complexity of life, the need to improve images appeared, especially when used in the fields of life, including industry and its branches, which affect the life of the citizen, such as the manufacture of fabrics. Which requires precision in the production of these fabrics from the colors and pattern of the fabric. Edge identification is the first step in many digital image-processing applications. Edge identification greatly decreases the data quantity, undesirable filters or unimportant data and provides the important data into the image. There are some issues such as false edge identification, noise issues, low contrast and other edge issues. This paper presents a practical study to compare different edge detectors to determine which edge detector achieves better results, which in turn reflects the best pattern in the fabric. These detectors are Canny, Roberts, Laplace and Gabor. A database of thirty color JPG images collected from the Internet was arranged and a quality scale was used to compare filter detectors. The system MATLAB2020 was used to program the proposed work. The results enhancement was measured by the quality coefficient. This coefficient estimated as follows for Roberts filter (44.27-51.09). Gabor filter (43.46-44.48) and Laplace filter (44.71-5.40). Finally, the quality coefficient for Canny filter equals (44.46-52.05). Therefore, it turns out that the Gabor filter is the best of these filters in defining the edges that were used in defining the pattern.

  • Improved Round Robin CPU Scheduling Algorithm with Different Arrival Times
           Based on Dynamic Quantum

    • Abstract: Modern operating systems are based on the principle of time-sharing in executing simultaneous operations. Determining the length of the time slice, and the times when processes arrive at the ready queue are problems that affect metrics such as the average waiting time (AWT), average turnaround time (ATAT), response time (RT), and number of context switches (NCS) of the time-sharing round robin RR algorithms. The research aims to propose an algorithm that achieves a short waiting time while maintaining a reasonable response time, which is the most important characteristic of time-sharing algorithms. The Different Arrival-Dynamic Quantum Round Robin (DADQRR) algorithm bases its work on different parameters to adjust the time slice value dynamically. The algorithm has been compared to three other algorithms that are similar in terms of dealing with different arrival times, namely AN, MARR, and RR. The algorithm outperformed the three algorithms at a range from 6.155% to 31.409% in terms of AWT. It achieved an outperformance of 5.924% to 30.850%, considering the TAT. The ranges of outperformance values resulted from the difference in the ranges of arrival times, as well as in the ranges of burst times.

  • The Effect of Azo Moiety on the Electrical Conductivity of Oxadiazole and
           Triazole Containing ...

    • Abstract: Phenolic mercapto oxadiazole and triazole monomers were prepared and then azotized with aniline and Para-phenylene diamine. The prepared monomers have been characterized with FTIR and1HNMR. The six prepared monomers were polymerized by condensation with formaldehyde in a basic medium. The polymer was recognized by FTIR, thermal analysis, and fine elemental analysis (CHN). The results have shown that the presence of azo moiety decreases the thermal stability and the glass transition temperature of the polymers. Also, the oxadiazole polymers are more thermally stable and have higher Tg than the triazole polymers. Doping with different ratios of iodine vapor was carried out on the polymer. The electrical conductivity of the pure and doped polymers was measured by using three probe cells. The results also revealed that the azo moiety increases the conductivity of the pure polymers to some extent (from 1.45534E-11 to 4.69038E-10 ohm-1cm-1  for oxadiazole polymers and from 1.15263E-10 to 3.2680E-10 ohm-1cm-1 for triazole polymers). It was also shown that the electrical conductivity was increased by many orders of magnitude (2-3 orders).by increasing the ratio of the doping.
