Abstract The description of the spectra tiling properties and Gabor orthonormal bases generated by the unit cubes and of the exponential for the 𝑛-cube are characterized. In addition the uniformity of non-uniform Gabor bases, atomic characterizations of modulation spaces through Gabor representations with Weyl-Heisenberg frames on Hilbert space, slanted matrices and Banach frames are clearly improved. We obtain the density, stability, generated characteristic function and Hamiltonian defo...
ABSTRACT The aim of this study is to measure the levels of serum electrolytes, trace elements and total iron binding capacity (TIBC) in Sudanese patients with leukaemia and to investigate the levels of these elements in leukaemia subtypes, in age, sex and related differences. Total of 201 persons were included; 79 (control group) and 122 (leukaemia patients). Serum electrolytes Na+,K+, Ca2+, Mg2+ and PO43- levelsanalysed by spectrophotometer. Trace elements Zn2+, Cu2+, Mn2+, Co3+ and TIBC by ...
Abstract In this research, a new modified version of Tree Dimension Playfair (3D-Playfair) cipher algorithm is introduce to encrypt image. The new method is create (16 X 4 X 4) matrix based on the key being entered by the user to become more secretive, and then manipulate image data the algorithm work on trigraph rather than using digraph, and to increasing complexity of the algorithm the key is used to generate a mask that is subsequently Exclusive OR (XORed) with the scrambled image after e...
Abstract Text mining is an important field in information retrieval; it organize a large number of text documents that available on the internet to facilitate the retrieved processing and increase efficiency. Text classification is automatically determining the category to new or unseen documents that depends on content of document itself. In text classification, text preprocessing is a fundamental step to obtained a better result. The Arabic text processing depends on stemming algorithms to ...
Abstract The results of this study were carried out to determine the composition of the uranium element in the Nuba Mountains area in Southern Kordofan region in the regions of Mount Uro and Mount Kurn. Forty samples were collected from the two regions, 20 samples from each region were grinded and converted into powder, and analysed by XRF spectrometer. To find the concentration of each element in the sample. The analysis showed that the average concentration of the uranium element in the sa...
AbstrAct This study was carried out in Central Blood Bank in Gadaref state to detect the infection rate of toxoplasmosis and malaria. Cross sectional study was carried out during period from May to September 2013. A total number of 100 studied population (age between 18-47 years old) were included in this study. Blood samples were taken from all subjects. Clinical and parasitological data was obtained and recorded.Thirty three out from 100 (33%) and 28 out of 100 (28%) Blood samples were fou...
ABSTRACT Banks face lots of challenges associated with the bank loan, Nowadays there are many risks related to microfinance in bank sector. Every year, we face number of cases where people do not repay most of the microfinance amount to the banks which they cause huge losses. The risk associated with making decision on microfinance request approval is massive. In this study a classification model was built based on the microfinance data obtained from an agricultural bank of Sudan to predict ...
ABSTRACT In this study, proximate analysis, jar test, turbidity, pH measurement and microbial count were carried out, to evaluate the coagulation and antimicrobial activities of Moringa oleifera seeds. Defatted Moringa oleifera seeds obtained by solvent extraction of Moringa oleifera seeds powder used n-hexane and seed cake was dried. Protein was obtained by extraction used NaOH. Results of this study revealed that seeds powder is rich in lipids (33.33%) and has carbohydrate, protein, moistu...
Abstract A Mobile Ad Hoc Network (MANET) is an infrastructure-less wireless network which allows a group of mobile devices to connect wirelessly without centralized administration. MANETs are useful when rapid deployment in infrastructure-less locations is required, or under emergency situations where communication is not available. Video conferencing over MANET is challenging due to features that characterize this type of network. This thesis proposed an enhanced scheme based on tuning, mod...
Abstract Fingerprints have many uses, chemical solution usually used to detect fingerprints but it takes a time. In this research He-Ne laser with output power 1mmW and wavelength 632.8nm and Diode laser with output power 5mmW and wavelength 532 nm were used to detect fingerprints on Aluminum surface and other Glass surface, fingerprints was exposure by laser beam through convex lens with focal length 5mm then a digital camera was used to record irradiated fingerprint. The revealed results s...
Abstract This study is an applied analytical one that helps in solving problems of the limit cycle and critical points for Planar systems. We introduced the classification of stable and unstable critical points of linear and nonlinear systems. The study found that the linear systems do not have a limit cycle. The study dealt with isolated limit cycle with its different patterns in an analytical and applied manner in the differential Planar systems of the second degree. The study investigated...
Abstract Construction industry is one of the major international industries and always takes place as agreat investment which needs huge capitals and wide experience. Contracts in the construction industry are fundamentals issues however technical support is necessary in all construction contracts for proper conduct adequate outputs. Usually contracts between different parties (contractor,client and consultant) include rights and obliquation which may not always be in abalance way. This migh...
Abstract Three brands of non-alcoholic carbonated soft drinks (CSDs) from three plants in Khartoum, Sudan which were named A, B and C; were examined for their microbiological quality. Plants were selected according to their quality system ‘A being the highest C being the lowest’. Samples were analyzed for (TBC); Yeast and Mold, coliform bacteria and acid tolerant microorganisms using membrane filtration method. Carbonated soft drinks from Plant C were the worst in microbiological quality...
INTRODUCTION Definition and Explanation of some Terms What is a chemical industry? It is difficult to define chemical industry exactly because of the absolute necessity for chemicals in almost every manufacturing industry. However, chemical industry can be defined as one that consists of all companies engaged in converting raw materials obtained from the environment (air, water, petroleum, minerals, agricultural products etc) into basic chemicals or chemical intermediates as well as the co...
In the health sector, the health of women is a significant public health issue, which impacts the personal well-being, family reproduction, and societal development. Therefore, knowledge about the health of women has led to an emerging requirement for healthcare sectors to obtain the real-time status and data of various applications that can improve the performance and accuracy of the health production. Globally, it has been found that women die due to pregnancy and childbirth consequences. T...
