Abstract
In this paper, the semi-empirical tight binding method for the nearest neighbors in the first Brillouin zone has been used to calculate the energy band structure of GaAs crystal which have zinc blend ZB structure, the band structure has been calculated by using sp^3 model which have 9 parameters and sp^3 s^* which have 13 parameters, both these models are used to calculate the main characteristic of both valence and conduction bands. The matrix elements were determined using the method followed by Cohen and Vogl, by identifying points in the wave vector space within the reduced Brillouin zone between the points of high symmetry and calculating the eigenvalues of all these points by building a computer program in MATLAB to form the energy band structure. The effective mass m^* along the direction [111] for the lowest conduction bands has been calculated. A comparison between the sp^3 model used by Cohen and the sp^3 s^* model used by Vogl has been made. The energies of the band structure at points the high symmetry Γ and X obtained from the study were compared with the results of the published research. The results showed that there is a difference in the energy gap between sp^3 and sp^3 s^* models and there is good agreement between the band energies at high symmetry points between these two models and the published results.

In this paper, porous silicon has been prepared and studied by photochemical etching method using a n-type silicon wafer with electrical resistivity (0.01-0.02 Ω.cm), orientation (100), hydrofluoric acid of 20% HF, current density of 15 mA / cm2 and etching time at (5 min). Silver nanoparticles (AgNPs) have been deposited using laser ablation by drop casting with different laser energy of 400,600 and 800m J. The electrical properties (I-V measurements) of silver nanoparticles on porous silicon have studied in both light and dark conditions. It can be seen the samples behave a rectifier and the current density increases with increase laser energy due to increase in concentration of silver nanoparticles, which lead to a decrease in the values of resistivity as the laser energy increases, this is attributed to the pores are filled with silver nanoparticles and lead to interference between silver and the porous silicon layer. The silver nanoparticles play an important role in forming a homogeneous layer and enhancing the crystal stability of the porous silicon layer.

Abstract
In this paper, the band structure of gallium group of III-V semiconductor has been calculated with temperature, the semi-empirical tight binding method was used to calculate the band structure and the matrix elements were calculated for both models sp^3 and sp^3 s^*. A computer program in MATLAB was designed to calculate the energy eigenvalues for the wave vector points in the first Brillouin zone between high symmetry points to form energy bands. The effect of temperature on the energy band of these group of crystals has been studied by changing the values of the lattice constant under the influence of temperature according to the Pierron relation and thus calculating the change in the length of the bond with temperature, which in turn affects the change in the values of the elements of the Hamiltonian matrix. The energy gap and refractive index were calculated at points of high symmetry as a function of temperature. The results showed a decrease in the energy gap values of GaAs, GaSb and GaP crystals with increasing temperature. Then the experimental Varshni relation was used to calculate the change in the energy gap values of these crystals and the results obtained from current study were compared with the results of Panish and Bellani, where the results showed that a model sp^3 s^* gives better results than the model sp^3.As well as the calculations of the refractive index of these crystals using the Moss formula showed that the refractive index will gradually increase with increasing temperatures.

The results of the study refer to the height of the electrical conductivity, which ranged between (791-2456) µmhos/cm. The results showed that a lot of water is free of dissolved oxygen, as it recorded the highest value of 4.6 mg/l. Whereas, the temperature of the studied water ranged between (20-28.4)Cº, and it is considered warm water. In the current study, the calcium ion concentration was greater than the magnesium ion concentration in all well water, and the highest concentration reached (264 and 134) mg/L at well 22 and 23, respectively. There was an increase in the concentration of chloride ion, which reached (204) mg/L and the lowest concentration (32) mg/l at wells 11 and 7, respectively.
When comparing the values of the electrical conductivity of the well water with the global determinants of drinking, it was determined that they are not suitable for drinking.
When applying the relationship between the value of the electrical conductivity and the ratio of sodium adsorption to well water, it was found that all water from wells Class (C3 - S1) except for wells (11 and 19) are classified as Class (C4 - S1)

The main purpose of this paper is to create a palmprint recognition system (PPRS) that uses the curvelet transform and co-occurrence matrix to recognize a hand's palmprint.
The suggested system is composed of several stages: in the first stage, the region of interest (ROI) was taken from a palmprint image, then in the second stage, the curvelet transform was applied to the (ROI) to get a blurred version of the image, and finally, unsharp masking process and sobel filtering were done for edge detection. The third stage involves feature extraction using a co-occurrence matrix to obtain 16 features, while the fourth stage inclusion is the training and testing of the suggested approach. The algorithm ACO (ant colony optimization) has been adopted to evaluate the shortest path to the goal.
CASIA PalmprintV dataset of 100 people (60 male and 40 female) was used in proposed work to rate the performance of the proposed system. ARR and EER metrics have been adopted to assess the performance of the proposed system.
The experimental results showed a very high recognition rate (ARR) that reaches 100% for the right hand of a male and the left hand of a female. The overall accuracy rate (ARR) reaches 98.5% and EER equals 0.015.

Vertical cavity surface emitting laser VCSEL is currently the main solution for many technological aspects, ultrafast optical interconnecting, Gigabit Ethernet, etc. In this paper we present the simulation results by using Optiwave™ software version 7, of the effects of optical mode confinement factor on the modulation properties)which inspected by eye diagram of the received signals)of the vertical cavity surface emitting laser VCSEL, with the range (8-20)Gbps of pseudo random bit sequence PRBS. The quality of the VCSEL modulation have been inspected by time domain signals, spectrums and eye diagram. Simulation results appeared an improvement in the characteristics of received bit sequences of (8, 10, 12.5, 16 and 20)Gbps bit rates, represented by the rising the value of quality factor QF (1.77 to 4.81) versus increasing the value of optical mode confinement factor Γ(0.2 to 0.5) respectively, and a decreasing in jitter time of superimposed traces of eye pattern and well opining eye pattern. And in the corresponding, the bit error rates BERs of the received signals have been decreased, with rising the value of mode confinement factor Γ of the laser at constant modulation index and constant temperature of the laser. Also, the VCSEL’s modulation response differences with different bitrates, causes different values of QF and BER for individual value of mode confinement factor Γ.

In every day, there is a great growth of the Internet and smart devices connected to the network. On the other hand, there is an increasing in number of malwares that attacks networks, devices, systems and apps. One of the biggest threats and newest attacks in cybersecurity is Ransom Software (Ransomware). Although there is a lot of research on detecting malware using machine learning (ML), only a few focuses on ML-based ransomware detection. Especially attacks targeting smartphone operating systems (e.g., Android) and applications. In this research, a new system was proposed to protect smartphones from malicious apps through monitoring network traffic. Six ML methods (Random Forest (RF), k-Nearest Neighbors (k-NN), Multi-Layer Perceptron (MLP), Decision tree (DT), Logistic Regression (LR), and eXtreme Gradient Boosting (XGB)) are applied on CICAndMal2017 dataset which consists of benign and various kinds of android malware samples. A 603288 benign and ransomware samples were extracted from this collection. Ransomware samples are collected from 10 different families. Several types of feature selection techniques have been used on the dataset. Finally, seven performance metrics were used to determine the best one of feature selection and ML classifiers for ransomware detection. The experiments results imply that DT and XGB outperforms other classifiers with best detection accuracy are more than (99.30%) and (99.20%) for (DT) and (XGB) respectively.

The detection and tracking of head movements have been such an active area of research during the past years. This area contributes highly to computer vision and has many applications of computer vision. Thus, several methods and algorithms of face detection have been proposed because they are required in most modern applications, in which they act as the cornerstone in many interactive projects. Implementation of the detected angles of the head or head direction is very useful in many fields, such as disabled people assistance, criminal behavior tracking, and other medical applications. In this paper, a new method is proposed to estimate the angles of head direction based on Dlib face detection algorithm that predicts 68 landmarks in the human face. The calculations are mainly based on the predicated landmarks to estimate three types of angles Yaw, Pitch and Roll. A python program has been designed to perform face detection and its direction. To ensure accurate estimation, the particular landmarks were selected, such that, they are not affected by the movement of the head, so, the calculated angles are approximately accurate. The experimental results showed high accuracy measures for the entire three angles according to real and predicted measures. The sample standard deviation results for each real and calculated angle were Yaw (0.0046), Pitch (0.0077), and Roll (0.0021), which confirm the accuracy of the proposed method compared with other studies. Moreover, the method performs faster which promotes accurate online tracking.

A study of the influence of the parameters design, such as the refractive index of the core, the cladding and the radius of the core on propagation constant (β) of single-mode optical fiber in optical communication region (1.2-1.6) m have been investigated. Material, waveguide, and profile dispersions are analyzed and investigated. Three models of optical fibers with different relative refractive indices () (0.004, 0.007, 0.01) at a wavelength equal 1.55 m, and three models of core radius (3,4,5) m is taken in the count. Numerical simulations and modeling are arranged depending on weakly guiding approximation for solving homogeneous wave equation derived from Maxwell’s equations. Our modeling solved by the aid of MATLAB software. Material and profile dispersion have no significant change for various relative refractive index, while waveguide dispersion is affected by the change of relative refractive index. the waveguide dispersion increased by increasing core diameter and the profile dispersion decreased as the core diameter increased. There is no effect on martial dispersion by increasing the core diameter.
