作者： Omar moh’d El-Basheer El-Ghezawi Electrical Engineering Department The University of Jordan Amman Jordan

A state feedback method of reduced order for eigenvalue assignment is developed in this paper. It offers immediate assignment of m eigenvalues, with freedom to assign the remaining n-m eigenvalues. The method also enjoys a systematic one-step application in the case where the system has a square submatrix. Further simplification is also possible in certain cases. The method is shown to be applicable to uncontrollable systems, offering the simplest control law when having maximum uncontrollable eigenvalues.

Case Reports in Clinical medicine 2023年第2期12卷 31-36页

作者： Anas Mahmoud Ahmed Salem Nizar Alyassin moh’d Azzam Department of Internal medicine St. Joseph’s University Medical Center Paterson USA

In our case, we present a case of a 27-year-old male who presented with progressively worsening altered mental status and seizures. Over the course of his admission to the hospital and intensive care unit, laboratory testing failed to find an offending agent to his presentation. Testing did result in the diagnosis of encephalitis, but an underlying cause was not found. After careful exclusion of bacterial, viral, and other types of encephalopathy, autoimmune encephalopathy was diagnosed despite the absence of commonly used markers of autoimmune encephalopathy. The presentation and symptoms of our patient led to a wide range of differentials, and a high index of suspicion was needed throughout his admission in order to obtain the appropriate tests. Although appropriate testing might be ordered, due to the sensitivities and specificities of all laboratory tests, these objective tests do produce false negative results at times. It is in these times that one must weigh the physical exam, clinical judgment, and the process of elimination to diagnose an underlying pathology. Autoimmune Encephalitis diagnosis can be broken down into possible, probable, and definitive diagnoses based on antibody testing results. In this case, we present a patient with probable autoimmune encephalitis that failed to yield positive autoimmune markers after extensive testing of other possible causes of encephalitis.

Intelligent Control and Automation 2013年第1期4卷 18-25页

This paper presents the design of an autonomous robot as a basic development of an intelligent wheeled mobile robot for air duct or corridor cleaning. The robot navigation is based on wall following algorithm. The robot is controlled using fuzzy incremental controller (FIC) and embedded in PIC18F4550 microcontroller. FIC guides the robot to move along a wall in a desired direction by maintaining a constant distance to the wall. Two ultrasonic sensors are installed in the left side of the robot to sense the wall distance. The signals from these sensors are fed to FIC that then used to determine the speed control of two DC motors. The robot movement is obtained through differentiating the speed of these two motors. The experimental results show that FIC is successfully controlling the robot to follow the wall as a guidance line and has good performance compare with PID controller.

Multiverse Spacetime

Journal of Energy and Power Engineering 2017年第9期11卷 584-588页

作者： K_haled (moh'dKhalaf) Suleiman Alnobani Chemical Engineering Jordan University of Science and Technology Irbid 22110 Jordan

A theological train of reasoning is avoided in this paper. The properties of the equal operator presented earlier by Alnobani are given here. A view of the present time is given. As a consequence of the presence of time state, the verses are arranged in couples and every verse including in which we live is a live verse in the same context of human life. This paper interferes with and changes the procedures and philosophy of mathematics itself. Space, mass and time are parts of one whole which is called simply time. The aim of this paper is to make the knowledge of its subject public, so other researchers can contribute to it. The concept of a gate between verses is investigated.

本文主要分析了导致坦桑尼亚于2000年退出东南非共同市场的主要原因。坦桑尼亚于1994年加入致力于区域经济一体化的东南非共同市场,希望通过成员国之间的贸易关系获得更多的利益。本文解释了东南非共同市场为什么未能达到坦桑尼亚的需求并导致其退出。坦桑尼亚改善贸易关系促进出口以及发展国内工业和中小企业的期望似乎落空了。坦桑尼亚和其他成员国之间的经济差距日益增加,20世纪90年代的坦桑尼亚是世界上最贫穷的国家之一。为了恢复经济,坦桑尼亚进行了各种努力,其中一个做法就是退出东南非共同市场这个区域经济一体化组织。为了分析坦桑尼亚这一令人意外的行为背后的原因,本文将试图回答以下问题:为什么坦桑尼亚会从东南非共同市场退出?研究结果表明,零关税协议是坦桑尼亚退出东南非共同市场的主要影响因素。百分之百削减关税是对坦桑尼亚的威胁,因为据2000年的贸易政策审查显示,坦桑尼亚严重依赖贸易关税和增值税的收入。因此,如果坦桑尼亚继续留在东南非共同市场,实施零关税可能会更多地影响其税收收入。根据东非贸易综合报告,新关税制度的实施将使政府每年投入8000万美元,同时,来自其他成员国的进口货物使维持本国市场的竞争力变得困难,进而影响国内产业的发展。因此,零关税协议的实施对坦桑尼亚的发展来说是一个障碍,这也是为什么坦桑尼亚在肯尼亚内罗毕举行的东南非共同市场首脑会议上宣布其退出决定的原因。坦桑尼亚联合共和国前总统本杰明·姆卡帕表示,坦桑尼亚的大部分国家收入来源是对外国货物征收关税,特别是来自刚果民主共和国、赞比亚、马拉维、布隆迪和卢旺达等周边内陆国家的外国货物。这些产品通常通过海关边境代理人缴纳关税,这也形成了坦桑尼亚必要的收入来源。据他所说,如果坦桑尼亚同意消除所有关税壁垒,将关税降至零,这将有损于坦桑尼亚的税收收入,进而影响经济的稳定性。本文由五章组成,第一章介绍了坦桑尼亚成为东南非共同市场成员的过程,进行该项研究的意义,本文的研究方法及文献综述。第二章梳理了坦桑尼亚退出东南非共同市场的阶段和程序。本章表明,坦桑尼亚经历了三个阶段。第一阶段是1999年5月20日至22日在肯尼亚内罗毕举行的东南非共同市场部长理事会会议,该会议以2000年10月31日东南非共同市场自由贸易区倒计时为主题,讨论了减免关税的相关议程。第二阶段是在部长会议之后一天举行的东南非共同市场首脑会议。在这次会议期间,坦桑尼亚已经表示打算在2000年之前退出东南非共同市场。第三阶段是坦桑尼亚退出东南非共同市场的议案得到了议会批准。第三章分析了影响坦桑尼亚退出东南非共同市场的经济因素。除了关税收入减少这个因素,坦桑尼亚退出的原因还包括对外贸易下降。加入东南非共同市场后,坦桑尼亚经历了贸易逆差,这也可能影响国内生产者。换句话说,坦桑尼亚的进口超出了出口。20世纪70年代,坦桑尼亚的进口和出口趋势稳定,与进口相比,其出口数额更多。但是,在20世纪80年代建立特惠贸易区和东南非共同市场后,情况开始发生变化:出口趋势下降到最低水平,导致了贸易逆差。从经济上来讲,当一个国家的进口数额超过出口时,会导致外汇储备短缺和经济稳定受到威胁。坦桑尼亚的贸易和经济形势非常严峻,这也使其为加强自身贸易模式而作出了退出区域经济集团的决定。第四章论述了坦桑尼亚从东南非共同市场获益不大是导致其退出的另一原因。与坦桑尼亚所属的其他区域经济一体化组织相比,例如东非共同体和南部非洲发展共同体,其在东南非共同市场成员国所属框架之内的出口水平并不理想。出口下降也影响了包括坦桑尼亚在内的成员国的农产品价值,1995-2000年坦桑尼亚的出口额在500万美元以下。另一项因素是会员的多重性在技术和经济上影响了坦桑尼亚的表现和承诺。坦桑尼亚不仅是东南非共同市场的成员,而且也是像东非共同体和南部非洲发展共同体等其他经济一体化的成员。多重会员资格是坦桑尼亚的主要障碍,这导致其在一体化组织中成为消极的成员。在经济上,坦桑尼亚不能为所属的一体化组织提供适当的财政捐助,而这些一体化组织的生存和发展依赖于成员国的财政捐助。各成员国一直在为道路建筑、铁路、水利设施和电力等各个开发项目提供财政预算,同时也为区域组织的行政管理提供运营成本。这对坦桑尼亚来说是一个负担,它无法按照要求提供这些捐款。唯一可以避免这种不便情况的方法是保持双重会员资格,这样就可以积极参与多项发展活动。同时,由于双重关税同盟的实行,多重会员资格也是一个障碍。世界贸易组织(wto)的规则和条例不允许成员国拥有双重的关税同盟协议,研究表明,东南非共同市场和东非共同体的成员都受坦桑尼亚所属的关税同盟协定的约束。如果坦桑尼亚继续留在东南非共同市场中,这将因为存在双重关税同盟而违反世界贸易组织(WTO)的规则。笔者在第五章基于在该研究中得出的结果,总结并给出了一些个人看法,同时还介绍了坦桑尼亚为加强与
