Abstract– World has turned into a global village. Fast growing economies has turned the way how world works. Old methods of software development are losing their grounds against agile development. Agile is paving its way to become the first choice of every person involved in software development. Agile development techniques are another name for delivering software product on time and within budget. Like all other developing techniques agile must have mechanisms to collect and manage requirements. This paper presents how different requirement engineering principles can be incorporated in agile development. Paper will cover different agile methods and requirement engineering techniques. There are lot of integration and differentiation in both techniques appears in this paper.

Positional Accuracy Testing of Google Earth

Sudan University of Science and Technology (sust.edu)

Abstract– Google Earth provides an open source, easy to access and cost free image data that support map interest community. Therefore, depending of this community on Google Earth, grows up day by day. More than simply providing locational information, Google Earth allows users to add their own content such as photos or descriptions of areas or landmarks. They can also extrapolate information from the satellite imagery obtained by digitizing areas of interest and exporting them for use elsewhere. As such, the application has found a strong following not only in explorers and navigators but also in classrooms all over the world. However, this popularity of Google Earth is not an indication of its accuracy. The aim of this research is to estimate the Google Earth horizontal and vertical accuracy in Khartoum State so as to evaluate this free source of data. This was carried out by comparing Google Earth measured coordinates of points with geodetic Global Positional System (GPS) receiver coordinates over sample of 16 check points located in Khartoum State....

Abstract– This study is to present the physical and mechanical properties of two species of dicotyledonous Irvingia species (Ogbono): Irvingia gabonesis (I.gab) and Irvingia wombolu (I.wom). In this study, some physical and mechanical properties were determined as a function of moisture content, and temperature variation under compression load. Four levels of moisture contents ranging from 10.6-43.14% d.b and 11.93-50.8%d.b for I. gab and I. wom respectively were used. The average length, width, thickness, arithmetic diameter equivalent diameter, and geometric mean diameter, seed volume and surface area were increased by 2.7, 1.0, 0.4, 1.6, 1.4, 1.3, 4.3, 2.5% for I. gab and 4.1, 0.1, 0.6, 2.2, 1.6, 1.6, 4.7, 3.3% for I. womb with increasing moisture content, respectively. The mass increased linearly from 391.5g to 416.5g for I. gab and from 442.5 to 466g for I wom....

Abstract– The use of Information and Communication Technology (ICT) has good impact on performance of businesses. Keeping a successful implementation of e-business in mind, governments decided to use ICT in public affairs in order to improve the performance of public sector organizations in the form of providing best possible information and services to citizens, businesses and other governments. With the passage of time computing technologies have made advancement and governments around the world were thinking to make good use of advanced computing technologies in government organizations. Today most of the countries are facing financial crises and as a result they are cutting extra spending and as a result governments are shrinking ICT budget. E-government is a huge project which requires good amount of money from the government. Some of the new inventions in computing technologies made it possible to reduce costs and increase efficiency and flexibility according to the needs of government sectors. One of the new inventions is cloud computing where information and computing services are provided as utilities. The use of cloud based e-government is to help the governments in providing best possible services to the citizens and businesses, and to reduce the costs as in cloud based e-government they will not require to purchase and install the ICT equipments on their own premises. In this paper we analyzed cloud computing and its applications in the context of e-government.

Abstract– This paper assesses the technological modality of using cloud computing in achieving cashless economy in Nigeria; this is with a view to establish a relationship between cashless economy and cloud computing. A desktop research approach was used to evaluate some technical details on the use of cloud computing in achieving cashless economy in Nigeria. Investigation revealed that the present banking transaction in Nigeria is poorly implemented and about 75% of business men are sceptical about doing their businesses online. The study also reveals that cloud computing will be a major job creation opportunities if fully adopted. In conclusion, appropriate policy suggestions were suggested for efficient use of cloud computing in achieving cashless economy in Nigeria.

The Effect of Ellipsoidal Reference Datum on Projected Coordinates in Sudan

Dr. Nagi Zomrawi Mohammed and Aiad Abbas Magboul Abbas

Sudan University of Science and Technology (SUST.edu)

Abstract– Clarke-1880 is the ellipsoidal datum on which Sudan maps are reduced to. Recently, Global Positioning System (GPS) receivers are widely used for coordinates determination in the country. Since GPS coordinates are reduced to World Geodetic System (WGS-84) then, differences in the coordinates of the same points may arise because of the difference in the reference datum used in each. This research work aims to compare between projected co-ordinates reduced to Clarke-1880 on Universal Transverse Mercator system (UTM) with the same points projected taking WGS-84 as a reference datum. Then, the effect of reference datum can be evaluated and judging its significance. Results proved that difference in northing is always larger than that in in easting, and the linear difference can be ignored in all quarter million maps and smaller.

Quantitative Analysis of Phosphorus Removal Based on its As-Beneficiated Content, Iron Extraction Rate and Input Concentration of H2O2

T. O. Chime

Department of Chemical Engineering, Enugu State University of Science and Technology, Enugu, Nigeria

Abstract– Quantitative analysis of phosphorus removal was carried out based on its as-beneficiated content, iron extraction rate and input concentration of hydrogen peroxide. A three factorial model was derived, validated and then used as a tool for the analysis. The model is expressed as: PR = 0.0006β2 - 0.0075β + α2 - θ + 0.382 The validity of the model was to be rooted on the expression PR - 0.382 + θ = 0.0006β2 - 0.0075β + α2 where both sides of the expression are correspondingly approximately equal. Statistical analysis of the model-predicted and experimentally removed phosphorus concentrations for each value of the input concentration of hydrogen peroxide and iron extraction rate considered shows standard errors of 0.0072 & 0.0055% and 0.0051 & 0.0049% respectively. Furthermore, removed phosphorus concentration per unit input concentration of hydrogen peroxide and iron extraction rate as obtained from model-predicted and experimental results were 0.0023 & 0.0015 %/M and 2.3167 & 1.5 mins respectively. Deviational analysis indicates that the maximum deviation of the model-predicted removed phosphorus concentration (from experimental results) is less than 6%. This implies that the derived model can exclusively be viably operational.
