In this paper, we propose a combination approach for face recognition based on combination of two
features extractor schemes named Singular Value Decomposition and Gabor filters. Singular value
decomposition (SVD) is a good method to extract image features because it has invariance for the
rotation and mirroring transformation, and also has better robustness for noise and light intensity
transform. Gabor filters produce perfect localization features in frequency and spatial domains. From
theexperimental results, the suggested approach obtains a good recognition rate. A recognition rate
of more than 98% has been achieved on the ORL database.The proposed approach has also been
compared to some existing techniques and the results obtained by the proposed method are far better
than these techniques.

Background: Human Cytomegalovirus (HCMV) is one of the causes of meningitis and can affect
the nervous system at all levels, from the hemispheres to the peripheral nerves, with presentations
reflecting the pattern of anatomic involvement.Aim of the study: To assess the role of Human
Cytomegalovirusin a cerebrospinal fluid (CSF) samples of Meningitis patientsusing Real time PCR
method.Materials and Method: This study recruited Forty-EightMeningitis patients (referred as
cases onward).The levels of glucose and proteins as well as cell cytology were used to roll out
patients with other types of meningitis.DNA was isolated from CSF samples obtained from each
participant. The HCMV UL36 gene was amplified with specific set of primers using Eva Green Real
Time PCR.Results:results proved that 4(8.4%) out of 48 samples were real –time PCR positive the
remainder 44 (91.6 %) were CMV real time PCR negative.Conclusion:Based on of these results, we
concluded that HCMV should not be rule out as one of the most important causes of meningitis in
Iraq.

AbstractText documents are the unavoidable form of information communication among humans, researchpapers on text hiding techniques are less in contrast to other cover object’s techniques. This is due tothat text documents have relatively less number of features (less redundant), that can be used to hidedata in comparison with other cover object types (image, audio, and video). In this paper, text hiding(Text-in-Text data hiding), algorithms is proposed and then coded in Matlab (m-files) form. Thealgorithm represents a new technique. It has many advantages over other existing text-in-text hidingtechniques. These advantages include the usage of Arabic or Arabic-English mixed for both thesecret and cover text with the aids of two of the nonprinting Unicode characters. Also applying newhiding rules concerning Arabic writing system. The cover text classified into groups of Arabic letterseach with specific features and thus hiding text between letters from these groups must be controlledby these new text hiding rules. Matlab programs for embedding and extracting the secret text,according to the new approach, are tested and the outputs have been found very satisfying. Bothsecret and cover text have the same original format and text configuration.

Traffic sign detection and recognition systems provide an additional level of driver assistance,
leading to improved safety for passengers, road users and vehicles. The automatic road-signs
recognition is an important part of driver assisting systems which helps driver to increase safety and
driving comfort. In this paper we proposed an efficient system for the detection and recognition of
the road sign in the road and acquiring the traffic scene images from a fixed source.The road sign
recognition system is divided into two parts, the first part is detection stage which is used to detect
the signs from a whole image by using the shape filtering method, and the second part is the
recognition stage where the traffic sign obtained is analyzed then the names and directions of cities
are extracted using the artificial neural network (ANN).The system accuracy more than 90%.

Images compression are just decreasing the quantity of data necessary to represent images. forcompressing the images efficiently and effectively we used a Different method to reducing the spaceand increasing the transfer efficiency of the image by the networks for superior access. This workaimed to create an image compression using modified Haar wavelet transform based on eight nodesto calculate the differencing and averaging in data transformation.The suggested procedure is to get maximum image compression ratio(C.R), high peak signal tonoiseratio (PSNR) ratio and less Mean Square Error (MSE). The proposed work has been examinedthrough many experiments, the results show very interestingresults in compression rates and thereconstructed image.The numerical work has been done by using matlab software.

Helical chaos appeared in the relation betweenimaginary part of laser field , real part of the same field and in the relation between imaginary part ofpolarization of the medium and real part of the laser field.

AbstractCloud cover is an important factor controlling the way that radiation is absorbed and reflected by theearth. Increases in cloudiness enhance global albedo, thus tending to cool the surface and the effecton earth's radiation characteristics and the climate in general, thus tending to global warming andclimate changes.In this work, is an attempt to investigate and understand the impact of solar activity on cloud coveramount over Baghdad city in 1983-2009 by analyzing the monthly values of cloud cover amount(low, mid-level, high and total), galactic cosmic rays, and the solar Modulation potential in1983−2009, and use package Climate Data Operators for this purpose.The first object of this study was to determine the solar activity index (the Solar ModulationPotential SMP) instead of (galactic cosmic rays GCR), SMP was selected as an indicator of solaractivity with a correlation coefficient (0.8) with GCR. The second object of our study was toinvestigate the relationship between the solar modulation potential (solar activity index) and cloudcover amount over Baghdad city for the period 1983−2009. The results showed that there is arelationship between the solar modulation potential and cloud cover amount for the period of studywith the highest coefficient of correlation was (R= -0.71 ± 0.22) between total cloud cover amountand SMP, and the lowest correlation coefficient was (R= -0.36 ± 0.34) for the high cloud coveramount with SMP. Therefore, we can assume that the solar activity has an impact on the cloud coveramount over Baghdad city.

AbstractThis study investigate in details the effect of the phonon vibration on the electrical properties forsome short sequences of DNA. The theoretical study is based on the Anderson-Holstein modelHamiltonian for small polaron and on the extended Holstein model Hamiltonian for large polaron.These models provides a convenient description of the charge transport with local and non-localelectron –phonon on site interaction. It is extensively, investigated the properties of the stationarystate polaron and the stady state polaron. Where, It is showed that the system parameters such uslocal and non-local electron-phonon interactions, the electron interaction between DNA bases, theDNA base vibration frequency and base on site energy all have pronounced effects on all kinds ofpolarons states .

In this article, thin films of copper oxide are prepared by synthesis of CuO nanoparticles using
different solvents by a low cost sol-gel method. Chemical bath deposition (CBD) method is used on
substrates of quartz glasses are dried in oven at 150 Ԩ for 3 hours. Finally these quartz glass pieces
are annealed at 500Ԩ for 1 hour. The structural and optical properties of the samples have then been
tested by XRD, SEM, FTIR and UV-Visible spectrophotometer. The crystallite size and strain are
higher for the CuO nanoparticle synthesized using propanol as solvent that shown by XRD analysis.
The blue shift of direct band gap and the red shift of indirect band gap indicated by UV-Visible
spectrophotometer Optical absorption analysis. So, the blue shift is due to the quantum confinement
effect seen for nanoparticle systems while the red shift is associated with the formation of surface
defects.

Using the Oguchi lattice, mixed spin 3/ 2 and spin 5/ 2 Isingmodel with different anisotropies
has been tested. The Helmholtzfree energy of a mixed spin Blume-Capel ferrimagnet from Oguchi
method of the Hamiltonian is calculated. By reducing the free energy, the equilibrium

temperaturehas been discussed as well. The results of this model has predict that the existence of
many(two or three) compensation points in the orderedsystem with z 6 is strongly dependent on
the crystalline magnetic anisotropy DB.
