  • A Review of the Control Techniques for Brushless Direct Current Motors (REVIEW PAPER) 

    A. Azami, M.؛ Faiz, Jawad. (Materials and Energy Research Center, 1999-02-01)
    This paper surveys the literature of the brushless DC motor speed control techniques. The paper should prove useful to both researchers as well as practising engineers as a signpost to the current state of the art. Based ...

  • a Comparative Theoretical Analysis for a Knitted Loop Model 

    Hamzeh, S.؛ A. Jeddi, A. A.؛ Latifi, M. (Materials and Energy Research Center, 1999-02-01)
    The theory presented in this paper differs from previous ones in that no arbitrary loop shape is assumed. Rather a strophoid curve, that is similar to knitted fabric Loop shape, has been assumed as the basic mathematical ...

  • Amorphous Silicon Flat Panel Imagers for Medical Application 

    Lee, H. K. (Materials and Energy Research Center, 1999-02-01)
    A new gamma camera based on hydrogenated amorphous silicon (a-Si:H) pixel arrays to be used in nuclear medicine is introduced. Various performance characteristics of a-Si:H imagers are reviewed and compared with those of ...

  • Single Server Bulk Queue with Service Interruption, Two Phase Repairs and State Dependent Rates 

    Jain, Madhu (Materials and Energy Research Center, 1999-02-01)
    This paper reports a study on a single server queue with bulk arrival and bulk service patterns wherein the incoming traffic depends on the state of the server which may be in operating or breakdown state. The repair of ...

  • Range Distributions of Low-energy Nitrogen and Oxygen Ions in Silicon (RESEARCH NOTE) 

    Zomorrodian, A. R. (Materials and Energy Research Center, 1999-02-01)
    The range distributions of low-energy nitrogen and oxygen (2-3 keV) ions is silicon are measured and compared with these available in theories. The nitrogen distribution is very close to a Gaussian distribution as predicted ...

  • Numerical Solution for Heave of Expansive Soils 

    Sadrnejad, S. A. (Materials and Energy Research Center, 1999-02-01)
    A numerical solution for heave prediction is developed within the context theories for both saturated and unsaturated soil behaviors. Basically, lowering the potential level of compressing on a saturated layer will cause ...

  • Elastic Initial and Post-local Buckling of Profiled through Girders 

    Bradford, M. A.؛ Azhari, M. (Materials and Energy Research Center, 1999-02-01)
    An experiment investigating the elastic local buckling response of trough girders composed of thin profiled steel sheeting has been undertaken Beam tests were performed to promote initial local buckling in a region of ...
