    200BP1 Prototype Hanford Barrier Annual Monitoring Report for Fiscal Year 2004
    (University of Khartuom, 2016-04-17) Seedahmed, Gamal H. ; J. K. Linville ; J. M. Keller ; Andy Ward ; Civil and Environmental Engineering
    In FY 2004, monitoring of the prototype Hanford barrier focused on barrier stability, vegetative cover, evidence of plant and animal intrusion, and the main components of the water balance. Monitored water-balance components included precipitation, runoff, storage, drainage, and deep percolation. Precipitation in FY 2004 was 26 percent less than in FY 2003 but was still higher than normal. The seasonal distribution in precipitation was also different from the previous year with a 43-percent reduction in spring precipitation and a 46-percent increase in summer precipitation. The cumulative amount of water received from October 1994, through September 2004, was 2,559.58 mm on the northern half of the barrier, which is the formerly irrigated treatment, and 1,886.71 mm on the southern non-irrigated treatments. Water storage continued to show a cyclic pattern, increasing in the winter and declining in the spring and summer to a lower limit of about 100 mm in response to evapotranspiration. The 600-mm design storage has never been exceeded. Total drainage from the soil-covered plots range from 2.9E-4 mm to 0.22 mm or 0.003 6 0.004 percent of precipitation. Side-slope drainage was much higher at 20.9 6 2.3 percent of precipitation from the gravel and 18.6 6 5.1 percent from the riprap. There was no runoff from the barrier, but runoff from the BY tank farm following a thunderstorm in May eroded a 45-inchdeep channel into the structural fill at the toe of the riprap slope. Above-asphalt and below-asphalt moisture measurements show no evidence of deep percolation of water. Topographic surveys were conducted on the barrier surface, including the two settlement gauges and 12 creep gauges on the riprap slope using aerial photogrammetry (AP) and a global positioning system (GPS). Comparing the aerial photogrammetry (AP) and global positioning system (GPS) surveys with the traditional survey shows the barrier and side slopes to be stable. Both AP and GPS show potential for considerable cost savings without any loss in accuracy. A relatively high coverage of native plants still persists after the initial revegetation in 1994. The formerly irrigated treatments continue to show greater cover of grasses and litter than the non-irrigated treatments. On the formerly irrigated treatments, the mean cover class was 25 to 50 percent for both grasses and shrubs. On the non-irrigated treatments, the mean cover class was 5 to 25 percent from grasses and 25 to 50 percent for shrubs. Species diversity of the vegetative community appears to have stabilized over the past several years. In addition to 12 of 17 species present in 2003 being present in 2004, two additional species were encountered. Sagebrush continues to flourish with shrubs along the perimeter showing higher biomass yield than the interior shrubs. There is evidence of sagebrush seedlings recruitment but not of rabbitbrush; the presence of gray rabbitbrush appears is declining as the barrier surface continues to stabilize. Use of the barrier surface by insects and small mammals is also evident. Small mammal burrowing on the barrier surface has become more prevalent in recent years, suggesting that the restored barrier surface is beginning to function as a recovering ecosystem. Small-mammal burrowing on the top and sides of the barrier is most prevalent on the finergrained and disturbed soils while active ant mounds were observed on the northern and western slopes.

    3-D GIS an Urban Planning for University of Khartoum Master plan
    (UOFK, 2014-05) Ibra, Sami ; Rabih,Abdalrahman ; Osman,Badreldin Taha ; Geographical and Environmental Sciences
    In city planning managing the third dimension is becoming a necessity. Using 3D GIS modeling within a GIS environment offers a flexible interactive system for providing the best visual interpretation because it aids the planning and decision-process. Previous 3D virtual models did not have to be completely accurate. It did need to be a relatively accurate representation of the true simulation of reality. The main objective of this research and by using ArcGIS Desktop and ArcGIS 3D Analyst is to build a master plan for the University of Khartoum campus to better understand and organize its utilities infrastructure to find a suitable procedure for acquiring geospatial information and makes it, accessible to administration, visitors, and students. Another objective in this study is to explore the capabilities of current technology software such as ArcGIS to link the spatial information about the building features and utilities within the map. In addition, this paper discurses the methodology and implementation steps which build a unified geospatial information system that can be used as an interactive system that supports planning decisions. The results the importance of campus planning as a focus in this work in order to demonstrate the effective use of 3D GIS modeling in the decision making process, a way to very quickly communicate ideas that help to make better decisions. The conclusion showed that the 3DGIS enable users to visualize complicated urban planning information in the 3D way, to evaluate the allowable capacity of the block and to simulate building plans. With visualization and analysis capability, 3D-GIS are considered a powerful tool to solve various issues which modern cities confront.

    34 Environmental Acquisition of inductive Bi-conditional Reasoning Skills : Training of simultaneous &Sequential processing.
    (university of khartoum, 2006) ElZubeir, Zeinab
    One hundred forty-four second-university students( Bio-medical engineering &Electronic engineering, University of Medical science and Technology(UMST) ) received training on one of three processing methods : coding-mapping (simultaneous), coding only, or decision tree(sequential) .Then they learned a bi-conditional rule under one of eight transfer test conditions based on a 2 ( paradigm: rule Vs complete learning) x (memory aids: 0 Vs 4)x2 ( focus instance: presence Vs absence ) design. Although the coding-mapping students processed concept instances in much the same way as the coding only students ,they acquired the target rule more frequently & they processed instances more quickly &more consistence than the decision –tree students . The observed ordinal of the responses of four truth-table classes was found to be more consistent with the simultaneity than with the sequential hypothesis .As expected training interacted with paradigm & also with memory aids & focus instance . The induced simultaneous processing strategy apparently works optimally under rule learning ,while the sequential strategy is difficult to induce &-or not optimal for rule- environmental learning operations

    3G Coverage Planning over Sudan using High Altitude Platforms (HAPs)
    (University of Khartoum, 2015-05-05) Musab Ali Eissa Ali ; Tahani Abdalla Attia ; Electrical and Electronic Engineering
    The provision of 3G wireless services to Sudan is proposed using a network of High Altitude Platforms, which are low cost, solar-powered and unmanned airships carrying multipurpose communications relay payload. These platforms are able to stay stationary at stratospheric altitudes, with a potential endurance of many years, features that make them attractive for the provision of future communication services. Several exciting research works are continuing into various aspects of this emergent technology. This thesis provides some insight into this infrastructure in terms of the need for a new system, its benefits, challenges, services provided and applications supported. A cellular network is designed to provide 3G coverage over sparsely-populated areas using large cells with small ones located inside these umbrella cells to serve hot-spot areas. Cell geometry is dimensioned, downlink budget is calculated and optimal values of link margin are estimated for different QOS requirements in order to determine the suitable scenario for each service. HAP Planning Tool is a Matlab simulation developed for this principle. Simulator results have shown that it is possible for HAPS based systems to provide 3G coverage within a cell diameter of 200 km. Low data rate services are accessible from any position of the cell, while high data rate services could be guaranteed only inside small circles around cell center

    A 4-Stories Building Elevator Control System
    (UOFK, 2012-07) El-Hassan, Nemat Hassan Ahmed
    The purpose of this project is to design, program and build "prototype" 4-story building elevator control using PLC. The PLC used is S7200 with 14 inputs and 10 outputs. The elevator should operate in a power saving mode; therefore an intelligent design is used. The elevator control system is programmed in a ladder diagram format into the PLC. The operation of the programmed PLC is first tested in a computer environment using a simulation program "MICROwin" before wiring the PLC to the hardware "prototype". Some suggestions on how to extend this system to the control of more than four floors are also included.

    A 4-Stories Building Elevator Control System
    (University of Khartoum, 2011) Omer, Hadeel Omer Dafa Allah
    This project is developed by using a Programmable logic controller (PLC) to control a 4-stories building elevator. The project system is running by calling each floor using the push buttons available at each floor and inside the car and the PLC would service your call as fast as possible. Floor sensors determine the current position of the elevator car and determine its direction (up or down). The program downloaded in the PLC determines whether the car would go up or down according to the last visited floor. As a result the car moves up and down according to the issued call and the last visited floor. After the program was tested a prototype developed and tested.

    5D3→7FJ emission of Tb doped sol–gel silica
    (University of Khartoum, ) Seed Ahmed, Hassan Abdelhalim Abdellhah ; Odireleng Martin Ntwaeaborwa ; M.A. Gusowski ; J.R. Botha ; R.E. Kroon
    Amorphous silica samples doped with 0.1 and 1 mol% of terbium (Tb) were synthesized by the sol–gel method. In addition to the green light associated with 5D4-7FJ transitions of Tb3þ, the sample containing 0.1 mol% also emitted blue light as a result of 5D3-7FJ transitions during photoluminescence (PL) measurements. As a result of concentration quenching this blue emission was not observed for the samples doped with the higher concentration (1 mol%). However the blue 5D3 -7FJ emission was observed in the 1 mol% doped samples during cathodoluminescence (CL) measurements. Since a rough calculation indicated that the excitation rate in the CL system where the blue emission is observed may be similar to a laser PL system under conditions where the blue emission is not observed, the difference is attributed to the nature of the excitation sources. It is suggested that during the CL excitation incident electrons can reduce non-luminescent Tb4þ ions in the silica, substituting for Si4þ ions, to the excited (Tb3þ)* state and that these are responsible for the blue emission, which does not occur during PL excitation
