Abstract Medical device is the key factor in making decision for patients; it is an important component in healthcare system, the development of new medical technologies can improve its ability of diagnoses and treatment. One of the most important steps of medical device life cycle is procurement and logistics which is regulated by federal ministry of health (FMOH). The most serious problem that encounters the tender procurement process in Sudan is that it is still paper based system. The me...
ABSTRACT Concrete is a mixture of fine aggregate (sand), coarse aggregate (rock), cement, and water. The increasing demand of concrete for construction and development of infrastructure has drawn the attention of many researchers in searching for less expensive alternatives to the traditional materials employed in the construction industries in an attempt to reduce the high cost of construction. This paper features an experimental study on the replacement of sand with quarry dust and its inf...
ABSTRACT Automatic and intelligent fire detection system is important for early detection and promptly extinguishing fire. Fire is a danger leads to quick destroying of assets and human lives. Moreover, it can propagate in fast manner according to several factors such as wind direction, fired contents (gas, fuel), etc. The fire is giant phenomena which can be controlled in its early stages but this period does not take except few seconds, there after it turns into a formidable force where to...
Abstract In the period between 2016-2019 and the problem of searching for roads lies in the cost and time of projects in the construction experience in Sudan from exceeding the time specified in the contract between the owner and the executing party and exceeding the cost in contracts The research aims to know the cost and time control, monitor the project status and forecast the final work cost, to address weaknesses and defects in the plan and early identification of risks at the beginnin...
ABSTRACT Weather forecasts are made by collecting as much data as possible about the current state of the atmosphere (particularly the temperature, humidity and wind) and using understanding of atmospheric processes to determine how the atmosphere evolves in the future. Weather forecasting is important in all walks of life and it enters agriculture, aviation, traffic, torrential floods and floods. Design weather temperature forecasting and implemented by using a sliding window algorithm appl...
Asynchronous Transfer Mode (ATM) of transmission is designed as a Broadband Integrated Services Digital Network (B-ISDN) transfer mode that supports a wide range of traffic classes with diverse flow characteristics. ATM guarantees different quality of service (QoS) demands placed on a network by different services (traffic types). The above powerful feats could be well achieved in ATM network with the application of an efficient and effective network resource management system. This thesis th...
Abstract Quantitative elastography is a non-invasive imaging technique that studies the elastic properties of the tissue when force is applied, and gives quantitative information about it. In this research the present work was performed using static deformation on a breast mimic ultrasound phantom. Strain images are constructed from the measured radio frequency (RF) ultrasound signals. The mean strain is recovered from stiffer segmented lesion and from nearby normal tissue, and then compute ...
Abstract Pain detection using a quick response method is considered an important point that must be considered especially for emergency medicine. This project presents new technique that records the myoelectrical activity of the stomach, which is effective due to its non-invasive nature and its correlation with gastric motility .The procedure was simulated with the aid of MATLAB 7.8 to generate a reference signal and another signal to indicate to the patient’s signal by using signal proces...
ABSTRACT This report presents a design and implementation of a microcontroller based remote controller for fan and lighting system with LCD indicator. It enables the user to switch ON and OFF the fan and lighting system from approximately 6 meters. The entire system is based on microcontroller that makes the control system smarter and easy to modify. The system ranges from a power supply unit to the control unit and the display unit which indicates when the system is turned ON or OFF. ln...
Abstract : IX The way people perceive the city’s elements at night is totally depends on lighting design and man-made facilities. Due to the development of cities’ economic and citizen’s life style, the nightscape of the city became as important as the appearance of the city at daytime and sometimes it is more important because it can make more impact on people’s minds about the city. Though the potential of Khartoum city to become an iconic lighted city on the Nile river, the city a...
Abstract In Long Term Evolution-Advanced heterogeneous networks, pico-eNBs are added to existing macro cells networks that contain macro eNBs in order to offload traffic from macro layer and bring users closer to the picoeNBs to enhance the cell edge user experience. Moreover, Cell Range Expansion (CRE) is a way to increase the percentage of users that associate to pico BSs which leads to reduce the imbalance traffic load between cells .However, there is strong interference which is caused b...
Abstract Competition pressures are forcing manufacturing companies to continuously seek new ways to manage their production capabilities more effectively in order to meet the demands of the market. In addition, to fulfillment of consumer needs and faster delivery times require efficient manufacturing controls and planning to ensure that productivity is maintained, stocks are minimized and resources are optimized. Part of management's drive in an organization is to ensure future sustainabilit...
Abstract In the last century, cardiovascular illnesses are the first death cause in developed countries. For this reason, many efforts have been made in order to develop sophisticated techniques for the early diagnoses of cardiac disorders. The Phonocardiogram (PCG) signals contain very useful information about the condition of the heart. By analyzing these signals, early detection and diagnosis of heart diseases can be done. It is also very useful in the case of infants, where ECG recording...
ABSTRACT Digital intercept receivers are currently moving away from Fourier-based analysis and towards classical time-frequency analysis techniques, such as the Wigner-Ville distribution, Choi-Williams distribution, spectrogram, for the purpose of analysing Low Probability of Intercept (LPI) radar signals.The LPI signals are difficult to detect, intercept and recognize, because they have many combined features implemented that help the LPI radar prevent its detection by modern intercept rece...
Abstract Clinical engineering using of biomedical engineering in the health institutions in order to provide excellent health services by adjusting the purchase of equipment and their uses and maintenance standards. The goal of the project is to design a program that helps in the management and organization the department of clinical engineering in health institutions. The project was accomplished using micro soft access programming language. The program depends on the inventory of the devic...
