Face Detection by Using OpenCV’s Viola-Jones Algorithm based on coding eyes
...Show More Authors

Facial identification is one of the biometrical approaches implemented for identifying any facial image with the use of the basic properties of that face. In this paper we proposes a new improved approach for face detection based on coding eyes by using Open CV's Viola-Jones algorithm which removes the falsely detected faces depending on coding eyes. The Haar training module in Open CV is an implementation of the Viola-Jones framework, the training algorithm takes as input a training group of positive and negative images, and generates strong features in the format of an XML file which is capable of subsequently being utilized for detecting the wanted face and eyes in images, the integral image is used to speed up Haar-like features calc

The Real and Imaginary Volume Integrals in Spherical-Statistical Optical Potential of Neutron scattering from 56Fe nuclei
...Show More Authors

A spherical-statistical optical model (SOM) has been used to calculate and evaluate the neutron interaction with medium nuclei (40 ). Empirical formulae of the optical potentials parameters are predicted with minimize accuracy compared with experimental bench work data. With these optical formulae an evaluation of the shape and compound elastic scattering cross-section of interaction neutrons with 56Fe nuclei at different energy range (1-20) MeV has been calculated and compared with experimental results. Also, volume integrals for real and imaginary potential energies have been evaluated and matched with the standard ABAREX code. Good agreements with have been achieved with the available experimental data.

The strong cryptography employed by PGP (Pretty Good Privacy) is one of the best available today. The PGP protocol is a hybrid cryptosystem that combines some of the best features of both conventional and public-key cryptography. This paper aim to improve PGP protocol by combined between the Random Genetic algorithm, NTRU (N-th degree Truncated polynomial Ring Unit) algorithm with PGP protocol stages in order to increase PGP protocol speed, security, and make it more difficult in front of the counterfeiter. This can be achieved by use the Genetic algorithm that only generates the keys according to the Random Genetic equations. The final keys that obtained from Genetic algorithm were observed to be purely random (according to the randomne

Dust storms are among the most important weather phenomena in Middle East. The Shamal dust storms are dominated across Iraq and the whole Middle East, especially in summer. However, frontal type of dust storms is possible in winter and spring. In this research, a comprehensive case study was conducted to a dust storm that occurred on 20 March 2016 from many perspectives: synoptic, satellite imagery, dust concentration analysis, visibility reduction, and aerosol optical depth. The study shows that the dust storm initiated inside Syria and moved eastward with the movement of the front. Dust concentrations and aerosol optical depth were also discussed that simulate the dust storm over Iraq in a reasonable way with some differences. The dust

Exploitation of Absolute qPCR to Estimate Lactobacillus and Bifidobacterium Count in Human Gut as Indicator of Diabetic Mellitus Complication
...Show More Authors

     Diabetes mellitus is a form of metabolic disorder where patients are incapable to organize glucose metabolism. The most common types are Type I and Type II, constituting about 10% and 90% of cases, respectively. The cause of type I diabetes, which usually spreads in children and adolescents, is the disability of the endocrine system to produce insulin. On the other hand, The most common type of diabetes,  type II diabetes, is often presented in adults. It is usually presented as a collection of insulin deficiency and insulin resistance. This work was done to estimate the count of microbiota in diabetics to find an appraoch for detection and follow-up treatment. The count of two types of bacteria Lactobac

In this paper a mathematical model that analytically as well as numerically
the flow of infection disease in a population is proposed and studied. It is
assumed that the disease divided the population into five classes: immature
susceptible individuals (S1) , mature individuals (S2 ) , infectious individual
(I ), removal individuals (R) and vaccine population (V) . The existence,
uniqueness and boundedness of the solution of the model are discussed. The
local and global stability of the model is studied. Finally the global dynamics of

Giardia lamblia is considered as one of most parasites that causes diarrhea in human. The present study aimed to investigate the relationship between giardiasis and ABO and Rhesus blood groups among local population. ABO and Rhesus blood groups were determined for 94 patients who gave positive result for Giardia infection. The ABO and Rhesus blood groups of these patients were compared with those of 196 non infected patients.
The frequency of ABO and Rhesus blood groups in infected patients does not differ significantly from those in non infected patients. ABO and Rhesus blood groups may not interfere with Giardia infection.

A total of 10 Pseudomonas aeruginosa isolates was collected from burns and wounds patients in different Erbil hospitals.
Nine of these isolates were resistant to Ampicillin, Gentamycin, Ciproflaxacin, Cephalexin, Erythomycin, and Chloramphenicol, but sensitive to Naladixic acid, Cortimoxazol and Polymexin-B. While the isolate P. E 10 is resistant to Naladixic acid in addition to above.
The bacterium was found to contain two plasmid bands on agarose gel.
Transformation revealed that the resistance to the antibiotics was encoded by non- conjugative plasmids while no correlation was found with virulence determinants.

ANT COLONY SYSTEM WITH MEDIAN BASED PARTITIONINGFOR IMAGE SEGMENTATION AND CLASSIFICATION

The motivation we address in this paper is to find out a generic method used to
segment and classify different types of conceptual images. A novel median based
method was proposed as primary stage for image segmentation, in which the image is
partitioned into fixed sized quadrants called kernels. The size of kernels in a specific
image is determined according to the spectral uniformity measurements. Later, Ant
Colony Optimization (ACO) is used to find out the optimal number of classes may exist
in the image, and then classify the image in terms of the determined classes. Different
types of images with different semantic concepts were used to test the proposed
classification method. The results obta

People who work on the analysis of seismic refection data usually use highly sophisticated software particularly when it is related to oil exploration data. In this article it will be shown how simple software like Reflex (2008) can deal with the seismic data with efficiency not less than professional software. Data of two seismic lines that were executed at Mansouriayah Oil field were used. After the filtering and processing reverse faults were detected. These faults isolate the top of Mansouriayah fold to form a gas reservoir. These types of reverse faults, which appear at the south western limb of the Mansouriayah fold, are also noticed for most High Folded Zone mountains. They are Gravity collapse faults that usually develop on both

Therefore, spam filtering has become a research fo-cus that attracts the attention of several security researchers and practitioners. Spam filtering can be viewed as a two-class classification problem. To this end, this paper proposes a spam filtering approach based on Possibilistic c-Means (PCM) algorithm and weighted distance coined as (WFCM) that can efficiently distinguish between spam and legitimate email messages. The objective of the formulated fuzzy problem is to construct two fuzzy clusters: spam and email clusters. The weight assignment is set by information gain algorithm.

FIELD-EMISSION INVESTIGATION OF COMPOSITE ADSORPTION LAYERS OF HYDROGEN AND HYDROGEN SULPHIDE ON TUNGSTEN
...Show More Authors

The interaction of H2 and H2S with tungsten, and of H2S with hydrogen-covered tungsten, has bean investigated in the field emission microscope. A number of chemisorbed states with varying heats of adsorption have been identified throughout H2 adsorption at a pressure of 10-5Nm-2 and 78K on tungsten. When H2S was adsorbed at 295K and gas pressure of 10-5Nm-2 on clean tungsten surface a preferential interaction occurred along the (111) zones. An increase in the average work function of 0.3V has been found for the process. Desorption of hydrogen, resulting from H2S adsorption, began at 1270K. Migration of the remaining sulphur began at 1400K while desorption occurred above 1500K and was complete at 1870K. Activation energies for the desorpt
