  • Speed Sensorless Vector Control of Induction Motors Using Rotor Flux based Model Reference Adaptive System 
    Ahmed , Aamir Hashim Obeid (Sudan University of Science and Technology, 2016)
    Vector Control (VC) schemes are increasingly used in Induction Motor (IM) drive systems to obtain high performance. However, in order to implement the vector control technique, the induction motor speed information is ...
  • Time Series Analysis of Nyala Rainfall Using ARIMA Method 
    Mohamed , Tariq Mahgoub; ibrahim , abbas abdalla (Sudan University of Science and Technology, 2016)
    This paper presents linear stochastic models known as multiplicative seasonal autoregressive integrated moving average model (SARIMA).The model is used to simulate monthly rainfall in Nyala station, Sudan. For the analysis, ...
  • Speed Estimation for Indirect Field Oriented Control of Induction Motor Using Extended Kalman Filter 
    Ahmed , Aamir Hashim Obeid (Sudan University of Science and Technology, 2016)
    ABSTRACT - Speed sensors are required for the Field Oriented Control (FOC) of induction motors. These sensors reduce the sturdiness of the system and make it expensive. Therefore, a drive system without speed sensors is ...
  • DES Security Enhancement using Genetic Algorithm 
    Mohammed , Ayman E.; Abdalla , Faisal M. (Sudan University of Science and Technology, 2016)
    In this paper is proposed method for creating Data Encryption Standard (DES) sub-keys. The proposal simplifies the creation and expansion process of the encryption key of the Data Encryption Standard (DES) algorithm, which ...
  • Influence of Ethanol or Water Injection on the Performance and Emission Parameters of Diesel Engine 
    Mahjoub , Mohammed Salih; Salih , Sabir Mohd; Hussan , Tagelsir Hassan (Sudan University of Science and Technology, 2016)
    A technology is implemented such that Ethanol or Water is introduced into the intake manifold through an injector while diesel is injected directly into the cylinder. In this paper, comparative experiments were performed ...
  • Investigation of Using Concrete Pavements in Developing Countries: A Case Study for Conditions of Khartoum State in Sudan 
    Ali , Gala; Akasha , .Nuha (Sudan University of Science and Technology, 2016)
    Recent years have witnessed several advances in pavement industry, such as superpave and asphalt-rubber mix-design, mechanistic-empirical design and pavement recycling. Nevertheless, development is lacking search for ...
  • Route Network Analysis in Khartoum City
