Image Resolution Enhancement Using Transform

In this project, interruption based image resolution enhancement technique using Discrete Wavelet Transform (DWT) with high-frequency sub bands obtained is proposed. Input images are decomposed by using DWT in this proposed enhancement technique. Inverse DWT is used to generate a new resolution enhanced image from the interpolation of high-frequency sub band images and the input low-resolution image. Intermediate stage has been proposed for estimating the high frequency sub bands to achieve a sharper image. It has been tested on benchmark images from public database. Peak Signal-To-Noise Ratio (PSNR) and visual results show the dominance of the proposed technique over the predictable and state-of-art image resolution enhancement techniques

Board Characteristics and Firm Performance Among Kuwaiti Companies

The issue revolving around corporate governance has always been an essential and critical element for both private and public sectors particularly in Kuwait. Kuwait's Prime Minister has even stressed for more concentration on the issues of governance for the purpose of overseeing the effective running of the public and private sector through a check and balance system. Moreover, the Prime Minister argued the need of the firms in the country to benchmark to an effective system that emphasizes on positive issues such as ethics, openness, accountability, transparency, and integrity in the public and private sector. Therefore, this crucial issue has to be addressed accordingly in order to enhance the performance of firms. It has been generally believed that good corporate governance is a critical factor in the improvement of firm value in both developing and developed financial markets. However, this belief overlooked the fact that the relationship between corporate governance and the value of a firm varies in developing and developed financial markets owing to the character of the corporate governance structures existing in the markets based on dissimilar social, economic and regulatory conditions. This reality calls for the need to examine and comprehend the differences affecting the firm value for the purpose of academic, financial and management practices and public regulation of markets and corporations. The core aim of the present study is the examination of the relationship between board characteristics and firm performance of non-financial, listed Kuwaiti firms on the Kuwaiti stock exchange. For the purpose of the study, data was collected from a sample of 136 companies for the financial year of 2009. Among corporate governance's various variables, five were chosen to be included in the study namely CEO duality, COE tenure, audit committee size, board size and board composition and one measures namely return on assets (ROA) was chosen as measures of firm performance. Furthermore, regression analysis was utilized for the examination of the relationship between board characteristics and firm performance. The result indicates that the relationship between CEO duality and ROA is positive in the significant level. Therefore, this result found that the relationship between CEO tenure and ROA is negative in the significant level. By contrast, this result found that the relationship between audit committee size with ROA is positive with significant level. In addition to that, this result found that the relationship between board size and board composition is negative but not significant. Furthermore, this study using firm size and leverage as a control variables found that the relationship between firm size and ROA is positively insignificant. Finally, the outcome of the relationship between leverage and ROA is negatively significant

Fuzzy C-Means Algorithm Based Satellite Image Segmentation

In this paper, an improved version of Fuzzy C-Means (FCM) algorithm is proposed efficiently to segment the satellite images. Segmentation of Image is one of the promising and active researches in recent years. As literature prove that region segmentation will produce better results. Human visual perception is more effective than any machine vision systems for extracting semantic information from image. A FCM algorithm is developed to estimate parameters of the prior probabilities and likelihood probabilities. So FCM algorithm is used for segmenting background and island extraction is done based on pixel intensity. Finally Peak Signal to Noise Ratio (PSNR) is calculated and it has better results than other

(Re-browsing the old calendar with a modern digital one using GIS-RS programs) and updating it to its digital form

Research and practical applications to update maps depend on successive steps and take into account the development of surveying devices and methods of producing old cadastral maps. which are the only maps available for ownership in Iraq, and that Iraqi government departments and Iraqi state departments use these maps. The research suggests a way to update old agricultural cadastral maps in Iraq by following a re-measurement-based modernization approach as an accuracy limit. Modern D.G.P.S scanning devices and GIS Software is used. to produce new and effective maps with a solid scientific update methodology. The study area is the Mosul district to which the methodology will be applied and the study area covers the Mosul district according to the approved index and old cadastral maps. The results of the study area showed that the methodology used in the research can produce a new correctly-measured map. The projection WGS 1984_ UTM Zone 38 in the Mosul

The study included two factors representing 4 levels of boron (0 , 25 , 50 , and 75 mg.L-1), three methods of seeds pretreatment  before planting (seeds without treatment, soaking the seeds for 24 hours with water, soaking the seeds with water for 12 hours and scratching their cover) , RCBD  where used with three replicates , the results show:                                                                                          There were significant differences between levels of boron spray and seed pretreatment method and their interaction on the positive effect on growth parameters and yield studied. The high levels of boron spraying led to early flowering , maturity and significant increase in plant height, number of branches, number of leaves, leaf area, chlorophyll content  percentage of dry matter, total number of  pods  per plant, the number of seeds per pod, weight of 100 seeds and the yield of plant compared to the treatment without spraying, the treatment of  boron spray  (75 mgm. L-1 ) gave low values to 50% flowering  90.8 days, maturity first pod of 98.5 days, while gave the highest average to growth and yield above was 72.67 cm, 6.10 branch, 84.97 leaf , 1006.03 cm2, 44.03 spad ,  30.54% , 22.40 pod per plant , 4.75 seed per pod , 198.55 gm ,  and 220.54 gm respectively, while the pretreatment of soaking the seeds with water before planting for 12 hours and scratching their cover gave the lowest period to 50% flowering  91.68 days and 101.88 days  to pod maturity and  highest average was 74.60 cm, 6.08 branches, 94.53 leaf,1093.67 cm2 ,  44.43 spad , 29.30%,  20.26 pod.plant-1 , 4.88 seeds.pod-1 ,  205.56 g , and 214.39 g respectively. While the interaction treatment  (spray boron 75 mg.L-1  + seed soaking with water to 12 hours) gave  less period to flowering and pod  maturity and highest values to above growth and yield parameters

SYNTHESIS, CHARACTERIZATION AND BACTERIAL ACTIVITY OF SOME METAL COMPLEXES OF N-PHENYL- Ń-(3-CARBOXYPHENOL) THIOUREA

A thiourea ligand; N-phenyl- Ń-(3carboxyphenol) thiourea (PCTH) is synthesized from the reaction of phenyl isothiocyanate with 3-aminobenzoic acid. Treatment of the ligand (PCTH) with metal salts MCl2, where M = Cu(II), Zn(II), Pb(II) and Co(II) gave metallic complexes of the types: 1- [M(PCTH)2Cl2] where M=Cu(II) and Co(II) and 2- [M(PCT)2] where M=Zn(II) and Pb(II). The ligand (PCTH) behaves as a bidentate and coordinated to the metal ion centers either through sulfur atom of its thioamide group and through nitrogen atom of the amine group or through oxygen atom of the carboxylic group. All the synthesized ligand metal complexes are characterized by micro-elemental analysis, IR spectroscopy and UV-Vis. spectroscopy, 1H.NMR, 13C.NMR, conductivity and magnetic susceptibility measurements. Finally, bacterial activity of the ligand (PTCH) and its metal complexes are tested against Klebsiella pneumonia and Escherichia coli and gram-positive bacteria Staphylococcus aurous. Using well-diffusion method and the results are discussed
