This research work, which presents a simplified technique of modelling steel fibers, uses python algorithm that can be directly run in ABAQUS to automatically generate the location and orientation of steel fibers in a rectangular ultra-high performance concrete specimen, so that the effect of steel fibers on the properties of such a specimen can be directly investigated through numerical simulation. This method is fast, can be applied to structural members of bigger dimensions (like beams,...
Linear analysis mostly applies to the problems that satisfy linear assumptions, materially linear problems that will have less displacements, less deformations, and boundary conditions which is constant. If any one of the above assumptions is not satisfied, a nonlinear analysis will have to be performed. ADINA Structures will provide powerful solving capacity and formulations which allows the solution of extremely complicated models with small CPU time and other memory requirements.

ABSTRACT In this work, models for predicting six structural characteristics and cost of sand-quarry dust blocks were developed. Three model equations namely Scheffe’s simplex lattice design (pseudo component), Scheffe’s simplex lattice design (component proportion) and Osadebe’s model were developed for each property. The properties investigated were Compressive strength, Water absorption and Split tensile strength. The others are Static modulus of elasticity, Flexural strength and She...
ABSTRACT The primary purpose of this study is to identify the causes of rutting in highway pavements in the form of channelization particularly on wheel tracks resulting from high traffic repetitions and environmental effects. The rutting reduces the required performance due to poor hot mix asphalt (HMA) components and construction to mention a few. The study focused on the impact of fine aggregate angularity (FAA) to increase Asphalt layer stability. AASHTO testing method (T 304) was appli...
ABSTRACT Data warehousing and business intelligence are key enablers in the drive to harness management information and improve decision-making. They underpin the recent wave of interest in data mining and customer relationship management, and create opportunities for performance improvements based on quantitative analysis at every le-vel in an organization. Data warehousing is a relatively new field in information technology, and current research centers primarily on data warehousing in bu...
ABSTRACT The rate at which roads fail in Nigeria should worry any responsible citizen. Considering the enormous resource expended to construct a kilometer of road, it is heartbreaking when the same road fail barely six (6) months after construction. For in the life of our dear country, the all-important economic theory of opportunity cost is applicable just as it is elsewhere in the world. Stabilization is a viable alternative to achieving a durable road construction regime. Soil stabilizati...
ABSTRACT With recent advances in wireless technology, users of wireless network now expect quality of service and performance comparable to what is available in fixed networks. The IEEE 802.11e Medium Access Control (MAC) is an emerging supplement to the IEEE 802.11 Wireless Local Area Network (WLAN) standard that supports Quality-of-Service (QoS) requirements of both data and real-time applications. The IEEE802.11e MAC is based on both centrally-controlled and contention-based channel acce...

ABSTRACT Paper based system for handling crime reporting becomes one of the challenging methods in police services globally ever since paper was invented. The South Sudan National Police Services (SSNPS) uses this system for handling crime reporting. This system presents a number of challenges such as a delay in disseminating crime reports by victims or witnesses, misplacement or loss of crime recorded files from the Police shelves and inconsistency of suspect documentation due to wrong man...
Abstract The transmission distance of any WDM fiber-optic communication system is eventually limited by fiber losses and it was introduced from fiber attenuation, connectors, splices, dispersion, interference and bending causes the power reduction in optical fiber communication. This loss limitation was mostly overcome using tunable optical filters, devices in which the desired channel is to be selected at the receiver with negligible crosstalk and small insertion loss. In this thesis diffe...
ABSTRACT Nowadays, water distribution network automation is becoming more and more popular day by day due to its numerous advantages, an internet-based water distribution network system focuses on monitoring and controlling water distribution network instance. Water distribution network face wastage of water due to improper water supply management, non-monitoring in real time, this caused scarcity of water, scarcity of water consider mainly problem in cities. water distribution network auto...
ABSTRACT The RADAR system is the first step and much more important and it has much more effect than the other step in the RADAR system works. The RADAR is used in different applications and systems, almost of these applications need high precision, and it's depending on the accuracy of RADAR ANTENNA orientation. Much research has been done and different systems designed to obtain a result within a permissible range. Design RADAR ANTENNA orientation and control system using FPGA and stepper m...
ABSTRACT This research dealt with the investigation of possibility of the use of the two representative seismic codes, UBC 1997, and IBC 2006, for seismic force analysis of R.C. buildings in Sudan. The theory of the seismic forces analysis was studied and presented. A R.C. building of eight storeys constructed in two sites, a very low seismic active site and a moderate seismic active site in Sudan which was analyzed by using ETABSv9.7.4 computer program. Utilizing data of the two sites, app...
