    Hussein, Rashid.A.M.; Elemam, Abusabah.E.; Mohamed, Sumya.A.; Ibrahim, Ahmed.A. (Sudan University of Science and Technology, 2014-12-04)
    This study carried out to assess the effect of increasing bentonite percentage (solid phase) on rheological properties and filtration loss for water base drilling fluid prepared from local bentonite (Umm Ali area). ...
  • Conflict Management and Preferred Style for Resolving Conflict 
    yousry, Mohamed Mohamed; El-Halwany, AbedEl-Aziz; Shiha, Eid Mohamed Fathy (Sudan University of Science and Technology, 2014-12)
    The purpose of this paper is what the common causes of conflict in Middle East (Egypt, Qatar, Jordan, K.S.A and Kuwait), and what is preferred style for resolving conflict in these countries. Conflict is inevitable and ...
  • Control of Induction Motor Drive using Artificial Neural Network 
    Ali, Taifour; Abbas, Abdelaziz Y. M.; Osman, Ekram Hassabo Abaid (Sudan University of Science and Technology, 2014-12-04)
    The induction motor drive is a dynamic nonlinear system with uncertainty in the machine parameters. The aim of this study is to improve tracking performance of the induction motor drive. A method for controlling induction ...
  • Deformational Mechanism and Tectonic Evolution of Mesozoic-Cenozoic Nonmarine Basins from Bohai Bay Basin - China 
    Hussein, Rashid A.M.; Xiaomin, Zhu (Sudan University of Science and Technology, 2014-11-04)
    Bohai Bay Basin，China, is a rift basin developed in Mesozoic-Cenozoic time span. It was compressionally deformed during Caledonian Orogeny and situated on a Paleozoic platform “old craton” basement and later subjected ...
  • The Effect of Motivation on Productivity in the Sudanese Construction Industry 
    Hassan, Awad Saad; Salim, Bakhit Elballa Ahmed (Sudan University of Science and Technology, 2014-12-10)
    Construction industry in Sudan is considered as the largest industrial sector that has a direct effect on the state economy. The productivity of this sector has declined in Sudan and all over the world since 1960. This ...
  • Influence of Flow Characteristics on the Design of Two-Phase Horizontal Separators 
    Mohyaldinn, Mysara Eissa; Ahmed, Masoud Gamiel (Sudan University of Science and Technology, 2014-12-22)
    Flouid streams produced from petroleum reservoirs reach surface as complicated mixtures consisting of multi-phase gas, oil, and water. Depending on the quantity of each phase, separators should be designed and installed ...
  • Innovation of New Cleaner Technology: Tannage by Local Tanning Agent Acacia Nilotica (Garad) and Aluminum Retannage 
    Hassan, Ebtesam A.; Ibrahim, Mohamed T.; A, Sally K. (Sudan University of Science and Technology, 2014-12-10)
    The present work was carried out to reuse chromium tannage and establish new cleaner technology by using vegetable tanning (garad) with aluminum alternatives to chromium tannage. Twelve pickled cattle hides were treated ...
  • Speed Control of Vector Controlled Induction Motors Using Integral-Proportional Controller 
    Ahmed, Aamir Hashim Obeid (Sudan University of Science and Technology, 2014-12-14)
    Control of Induction Motor (IM) is well known to be difficult owing to the fact the mathematical models of IM are highly nonlinear and time variant. The advent of vector control techniques has solved induction motor ...
