فیصل، شاہ ( شہید )
کل شیء ھالک الا وجھہ
گزشتہ مہینہ شاہ فیصل کاحادثۂ شہادت موجودہ حالات میں عالم اسلام کا سب سے بڑا المیہ ہے جس کی شدت کوایک مدت تک فراموش نہ کیاجاسکے گا۔ مرحوم اس زمانہ میں عالم اسلام کی آبرو، عزت و وقار اورتمکنت تھے۔ قدرت نے انھیں سوز اورساز دونوں نعمتوں سے نوازا تھا۔کہنے کوخادم حرمین شریفین تھے لیکن درحقیقت وہ پاسبان ونگہبان حرم اسلام تھے۔ نورایمان ویقین ان کاجوہر ذاتی، تعامل بالکتاب والسنۃ ان کاآئین حقیقی، فہم وفراست اورتدبر و دوراندیشی ان کی طبیعت کے گوہر آبدار تھے۔ مرحوم کی سربراہی کی مدت گیارہ برس سے زیادہ نہیں ہے، اوریہ وہ زمانہ ہے جب کہ عالم اسلام اندرونی وبیرونی اسباب وعوامل کے باعث شدید کشمکش امید وبیم سے دوچار تھااوراس کے سرپر اضطراب وتشویش کی قیامتیں مچل رہی تھیں، لیکن شاہ فیصل کی قائدانہ بصیرت وبصارت نے وہ معجزہ نمائی کی کہ عالم ہی دوسرا ہوگیا۔ امریکہ جواس وقت دنیا کی سب سے بڑی طاقت و قوت ہے اورسیاست’’ فرنگ‘‘__جواس دور کا سب سے بڑاحربہ ہے، دونوں نے اس طرح سپرافگنی کی کہ روس اورامریکہ کے بجائے عالم کی نظریں شاہ کی جنبش مژگان وآبروپرمرتکز ہوگئیں اورامریکہ کے ٹائمز وغیرہ کوتسلیم کرنا پڑا کہ اس زمانہ کاسب سے بڑاسیاسی اورطاقتور انسان شاہ فیصل ہیں۔ یہ انھی کا حوصلہ تھا کہ عرب کی طاقت کالوہا دنیا سے منوالیا،انھوں نے عرب ممالک میں اتحاد پیدا کیا، انھیں خوداعتمادی سکھائی، عرب قومیت کی لعنت سے نجات دلا کرانھیں صراط مستقیم پر گامزن کیا۔ان کے دل میں اسلام اورمسلمانوں کادرد کوٹ کوٹ کر بھرا ہوا تھا۔ انھوں نے اربوں اورکھربوں روپیہ سے ضرورت مند عرب اوردوسرے عرب اسلامی ممالک کی بے تحاشا مدد کی، دنیا میں جہاں کہیں بھی مسلمان آباد ہیں ان پر اُن کی نگاہ رہتی اوراُن کے فوزوفلاح کی تدبیر...
The study investigated school business competencies for improved administrative effectiveness in Public Secondary School in Rivers State. Three research questions and two null hypotheses were formulated to guide the study. The population of the study was 286 principals in all the public secondary schools in Rivers State. A sample of 166 through a stratified random technique was determined using the Taro Yamane formula. The instrument of the study was a self design instrument captioned “School Business Management Competencies Questionnaire (SBMCQ) and Principal Administrative Effectiveness (PAE) with the reliability coefficients of 0.77 and 0.84 respectively which was determined through the Cronbach alpha statistics. Mean scores and standard deviation was used to answer the research questions while Pearson Product Moment Correlation Coefficient was sued to test the hypothesis. It was discovered that the highest kind of business available in the public school is related to cafeteria / canteen services and that also to a high extent, resourcefulness as a business management competency improves administrative effectiveness in public secondary schools in Rivers State. It concluded that for the school administrators to manage the school business effective (administrative effectiveness), they must possess the core competence of resourcefulness, conceptual thinking and administrative organisation. It was recommended among others that the principal should have a comprehensive understanding of the school complex nature and also think critically at both abstract and concrete level to harmonize a rather multifaceted business challenges in the school and proffer realistic solutions.
The radiation pattern and other electrical characteristics of an antenna primarily depend on its size and geometry. In the current age of communications, it is highly desirable to have compact and light weight communication devices. Therefore the most challenging issue of today’s wireless communication systems is to design antennas which are cost effective and of compact size without compromising the radiating efficiency and effectiveness. Since microstrip patch antennas are light weight, compact, easy to design and install; they are the best choice for today’s communication devices. That’s why patch antennas are widely used in numerous wireless applications as a single radiating element and as an array of multiple elements. However, designing of different shaped antennas to suit the electrical and/or physical requirements of the communication system is not an easy task. In this dissertation we have successfully designed microstrip patch antennas to achive desired electrical charcteristics such as frequency, bandwidth and quality factor alongwith the targeted physical characteristics such as length, radius or area etc. Keeping in mind the utilization of various shapes of antennas in communication systems; the dissertation includes designing of different geometrical shaped patch antennas such as square, circular and hexagonal. In addition to design patch antennas, we have succefully designed array of patch elements to be used in MIMO systems. The array has been designed for the desired electrical characteristics such as directivity, frequency, and return loss etc. Moreover, using this array design model, we estimated the channel capacity for ferquency selective Rayleigh fading channel. Since ultra wide band frequency systems are suitable for high data rates with low power consumption, we have particularly focused on this range of frequncy for antenna designing. Among all the heuristic approaches, literature shows that particle swarm optimization (PSO) and genetic algorithm (GA) are the most efficient and effective heuristic approaches in solving the problems of antenna and electromagnetics. Therefore we have employed these two approaches for designing and optimizing these antennas. We have also developed a new heuristic algorithm namely Wildebeest Herd Optimization (WHO) algorithm. It is based on the living wildebeest in their herd and migrating from one point to another for food and water. All the multi-geometrical antennas have been designed and optimized on WHO in addition to GA and PSO. The comparative analysis verifies that the proposed algorithm is more effective and efficient than the existing heuristic approaches. Moreover, artificial neural network (ANN) is employed to model the electrical/magnetic behavior of single antenna and arrays. The outcome of ANN models are compared with the results of numerical computational software Ansoft HFSS. In the light of this work, various future recommendations are also given at the end.
