Customization Of CMMI Model For Small Enterprises In Sudan

Abstract Sudanese software enterprise which categorized as small enterprises need frameworks and models for process improvement . Capability Maturity Model integration (CMMI ) which is designed for large scale enterprise is not suitable for Sudanese enterprise and need to be customized to suit small enterprise . The current study aims to investigate software process improvement in Sudanese software enterprise and to customized process improvement. Capability Maturity Model integration (CMMI ...

A Web-based Model To Determine Security Risk Exposure Index Among Savings And Credit Cooperative Societies

Savings and Credit Cooperative Societies (SACCOs), like other financial institutions, own critical assets that must be protected against attackers even as the threat landscape continue to persist. This study provides a solution to SACCOs by determining security risk exposure index (SREI) based on ISO/ 27001 standards. The objectives of the study were to determine the critical security risks factors affecting Selected SACCOs based on ISO 27001 standards, to design a model for computing th...

Antimicrobial And Antioxidant Activity Of Rosmarinus Officinalis L. Flowers Pods And Thymus Vulgaris L. Leaves Ethanolic Extract On Escherichia Coli Urinary Isolates

ABSTRACT The indiscriminate use of antibacterial agents has led to one of the largest recent global health problems which is the emergence of bacterial resistance. The present study was aimed to investigate the antimicrobial and antioxidant activity of ethanolic extracts of the two medicinal plants; Rosmarinus officinalis L. and Thymus vulgaris L.on Escherichia coli (E.coli). Antibiotic susceptibility test was applied against E.coli urinary isolates using Chloramphenicol, Gentamycin, Amoxici...

Effect Of High Temperature On Metals And Semiconductors

Abstract The electrical property of noble mineral ( platinum( 58 680 sample and semiconductor 586 821were studied , at temperatures up to 100C0, 373 Kelvin. It was found that the temperature increases mineral resistivity and decreases it is conductivity ,the resistance and conductivity f or the mineral we found to be equal to R = 106.3 Ω and σ = 0. 01176 respectively . The resistance and conductivity for semiconductor were also obtained . It was found that increasing temperature decreases ...

Implementing Integrating Enterprise Systems In Sudan -Using Enterprise Service Bus (Esb)

Abstract The main objective of this research is to implement an enterprise system integration using an enterprise service bus (ESB) in Sudan. The research questions are; what framework to be used to complete the integration? And what are the mechanisms that will be used to make sure that the integration process is successful? Finally, how to choose the workflow engine and what are the criteria for the choice. To achieve the research objectives, different approaches to integrate enterprise sy...

Course Catalogue Handling System (CCHS)

ABSTRACT In an academic setting, it is important for students to be well informed about their academic status and progress regularly. All first year students are provided with school catalogs which hold information about their majors and the courses required by them to pass for them to obtain their particular degrees. Students are given these catalogs only once and many of them tend to misplace them after a few semesters. Hence, they lose information on the requirements they need to obtain a...

A Review Of Dimensionality Reduction Methods And Their Applications

ABSTRACT In the world we live in today, the reduction in data generally has seen a great rise. This is because of the numerous advantages that comes with working with smaller efficient data instead of the original large dataset. With this analogy, we can adopt Dimensionality reduction in computer science emphasizing on reducing computer memory in order to have more storage capacity on a computer. An example of this would be to reduce digital images which are then stored in 2D matrices. Dimen...

Voice Encrption In Gsm Network Using Rc4 Algorithm

Abstract Mobile telecommunications such as Global System for Mobile Communication ( GSM ) are now well established globally and users rely heavily on the convenient communications it provides. The level of security provided by GSM is superior to its predecessors and is more than adequate for the majority of users. However, some users in the areas of government, defense or business require more security over and above that provided by the GSM standards and by standard GSM equipment. In a GSM n...

Design And Implementation Of SITC Faculty Portal

ABSTRACT American University of Nigeria (AUN) has many web application used every day both by students and faculty. For students, faculty and other staff to know about a course or department; they have to visit the AUN website and they can only have little information about them. This problem is faced by students, faculty and visitors that want know about the school of information, technology and computing in the American University of Nigeria. SITC is the second largest school in AUN and it...

Optimization Of Radiation Dose And Image Quality In Computed Tomography Imaging

Abstract Improvements in the benefit of CT have been so dramatic that a tendency exists to the overuse. CT is a diagnostic imaging modality giving higher patient dose in comparison with other radiological procedures. While the benefits of CT exceed the harmful effects of radiation exposure in patients, increasing radiation doses to the population have raised. The main objective of this work was to find an optimization approach to minimize the radiation dose to adult patients undergoing CT ex...

Interpolation Of Spot Heights In Seloum Dry Port

Abstract Leveling is a branch of surveying and one of its targets to find out the topography of earth surface, more over it is required in the setting out of all kinds of engineering works. Creation of Dry ports are to help costal ports and they need to be interconnecting by road and rail infrastructure. Planning and design of Dry ports as large area are looks like container ports at system and aspects. Apprehensible of interpolation deals with knowing or telling what is going to happen, o...

Evaluation Of Conventional X-Ray Machines In The Primary Health Care Centers In Khartoum State

Abstract This study evaluate 27 X-ray units worked in the Primary Health Care Centers in Khartoum State, these units divided in three groups according to the manufacturing company, the first group acts as 66.7% of units under study it has mechanical problems which make the move of unit too difficult also there is a problem in kilovolt and time accuracy .The second group acts as 22.2% of all units which has programming and software problem. The third one acts as 11.1% of all units which has n...

Rates Of Parasitic Contamination For Arachis Hypogaea L (Groundnuts) , Citrullus Lanatus Seeds (Watermelon Seeds) , And Ziziphus Spina-Christi Fruit (Nabag) Sold By Street Venders In Khartoum

Abstract Various plants products including seeds are an important source for vitamins, minerals, proteins, and energy. Predominantly they are eaten fresh and uncooked or even if it they are cooked; they are handled in un-hygienic manner that change them to a major source of intestinal infection. This study aimed to assess the parasitic contamination in roasted groundnut, nabag, and tasali sold by street venders at Khartoum state, Sudan at the period from July 2019 to January 2020. A total of...

Assessment Of Technological Risks Facing Mobile Banking: A Case Of Commercial Banks In Kenya

Mobile banking technology has been widely adopted amongst all the commercial banks in Kenya. Currently Kenyan banks lose millions of shillings by means of online theft through mobile banking and other platforms. This study therefore intended to address the issues associated with mobile banking and was directed by the following objectives: to understand the mobile banking architecture, to establish the technological risks arising for commercial banks in Kenya as a result of mobile banking, to ...

Assessment Of Radiation Dose For Patients Undergoing Brain And Abdomen Computed Tomography

Abstract Computed tomography (CT) is an imaging technique which produces a digital topographic image from diagnostic x-ray. It always considered a “high dose” technique, there is growing realization that image quality in CT often exceeds the level needed for confident diagnosis and that patient doses are higher than necessary. The aim of this study was to evaluate the level of radiation dose received by the patients during brain and abdomen CT examination. In this study, a total of 128 a...
