Quasi Semi and Pseudo Semi (p,E)-Convexity in Non-Linear Optimization Programming
...Show More Authors

The class of quasi semi -convex functions and pseudo semi -convex functions are presented in this paper by combining the class of -convex functions with the class of quasi semi -convex functions and pseudo semi -convex functions, respectively. Various non-trivial examples are introduced to illustrate the new functions and show their relationships with -convex functions recently introduced in the literature. Different general properties and characteristics of this class of functions are established. In addition, some optimality properties of generalized non-linear optimization problems are discussed. In this generalized optimization problems, we used, as the objective function, quasi semi -convex (respectively, strictly quasi semi -convex functions and pseudo semi -convex functions), and the constraint set is -convex set.

Automatic Image and Video Tagging Survey
...Show More Authors

     Marking content with descriptive terms that depict the image content is called “tagging,” which is a well-known method to organize content for future navigation, filtering, or searching. Manually tagging video or image content is a time-consuming and expensive process. Accordingly, the tags supplied by humans are often noisy, incomplete, subjective, and inadequate. Automatic Image Tagging can spontaneously assign semantic keywords according to the visual information of images, thereby allowing images to be retrieved, organized, and managed by tag. This paper presents a survey and analysis of the state-of-the-art approaches for the automatic tagging of video and image data. The analysis in this paper covered the publications

Large-Coessential and Large-Coclosed Submodules
...Show More Authors

The goal of this research is to introduce the concepts of Large-coessential submodule and Large-coclosed submodule, for which some properties are also considered. Let M  be an R-module and K, N are submodules of M such that , then K is said to be Large-coessential submodule, if . A submodule N of M is called Large-coclosed submodule, if K is Large-coessential submodule of N in M, for some submodule K of N, implies that  .

Synthesis and Characterization of Cu2FeSnSe4 Nanofilms
...Show More Authors

Well dispersed Cu2FeSnSe4 (CFTSe) nanofilms were synthesized by hot-injection method. The structural and morphological measurements were characterized using XRD (X-ray diffraction), Raman spectroscopy, SEM (scanning electron microscopy), and TEM (transmission electron microscopy). Chemical composition and optical properties of as-synthesized CFTSe nanoparticles were characterized using EDS (energy dispersive spectroscopy) and UV-Vis spectrophotometry. The average particle size of the nanoparticles was about 7-10 nm. The UV-Vis absorption spectra showed that the synthesized CFTS nanofilms have a band gap (Eg) of about 1.16 eV. Photo-electrochemical characteristics of CFTSe nanoparticles were studied and indicated their potential application

Iraqi Digital Art: Origin and Evolution
...Show More Authors

The current challenge facing our age is the information digitization, at the same time, there is a huge development in the interdisciplinary of technologies with sciences. In the last few years, the World witnessed a number of information challenges with different dimensions, including digital dimensions, which are called the digital world and the virtual world for authors and movie writers. Consequently, the digital art concept emerged that utilizes the computer in an efficient way and as a new technique for drawing. This art is considered a great leap for modern art. The influence of digital technology transformed traditional arts like painting and sculpture into new forms, from pure arts to virtual reality. The most important characte

Congenital diaphragmatic hernia: prevalence and management
...Show More Authors

Background: The morbidity and mortality of congenital diaphragmatic hernia is related to the severity of lung hypoplasia ,pulmonary hypertension and associated anomalies.
Patients and methods: fifty nine consecutive patients with surgically proved diaphragmatic hernia (excluding hiatal hernia) were included in this prospective study. All patients were seen at Al- Kadhymia hospital for children and Al-Mustansyria hospital, in the period from January 2003 to December 2009.Plain chest x-ray was done for all the patients understudy, but barium study was arranged for only nine patients.
Results: There were fifty nine child with congenital diaphragmatic hernia , Bochdalek hernia forms 81.4% of all congenital

Pure Maximal Submodules and Related Concepts
...Show More Authors

      In this work we discuss the concept of pure-maximal denoted by (Pr-maximal) submodules as a generalization to the type of R- maximal submodule, where a proper submodule  of an R-module  is called Pr- maximal if  ,for any submodule  of W is a pure submodule of W, We offer some properties of a Pr-maximal submodules, and we give Definition of the concept, near-maximal, a proper submodule  

 of an R-module  is named near (N-maximal) whensoever  is pure submodule of  such that  then K=.Al so we offer the concept Pr-module, An R-module W is named Pr-module, if every proper submodule of  is Pr-maximal. A ring  is named Pr-ring if whole proper ideal of  is a Pr-maximal ideal, we offer the concept pure local (Pr-loc

Cervical Spondylosis, Surgical Management and Outcome
...Show More Authors

Background: Cervical spondylosis is a degenerative disease of the cervical spine and can occur at any age but mostly after 5th decade.

Objectives:  is to focus a light on the clinical features, radiological findings and the result of the surgical treatment with comparison to the global results in the same field.

Patients and method: This is a prospective study of 50 patients with cervical spondylosis managed with surgery at surgical specialty hospital in the medical city, Baghdad, from the period from Jun. 2011 till Jan. 2012. The clinical, radiological, neurophysiological studies together with surgical outcome were all reviewed and included in the study.

Disc Laser System Construction and Characterization
...Show More Authors

 In this work a Nd:YVO4 thin disc laser setup is designed and fabricated. The disk laser system
is designed to be compact. The laser crystal was pumped by a 808 nm diode laser. The effect of input
current and pulse frequency on the output energy at pulse operation mode, and the effect of the input
current on the output power at CW mode operation are tested. At the pulsed mode, the output energy
increased linearly with the input current and decreased with pulse frequency. The threshold current
increased with increasing pulse frequency increasing. The maximum output energy from the thin disc
laser was 0.98 μJ at 1.3 kHz frequency, with 0.49A. A minimum threshold current for CW mode of
operation. The maximum outpu

ET-Coessential and ET-Coclosed submodules
...Show More Authors

Let M be an R-module, where R be a commutative;ring with identity. In this paper, we defined a new kind of submodules, namely; ET-coessential and ET-Coclosed submodules of M. Let T be a submodule of M. Let K  H  M, K  is called  ET-Coessential of H in M (K⊆ET.ce H), if     . A submodule H is called ET- coclosed in M of H has no proper coessential submodule in M, we denote by  (K⊆ET.cc H) , that is, K⊆ET.ce H implies that   K = H. In our work, we introduce;some properties of ET-coessential and ET-coclosed submodules of M.
