زبان اور نئے بیانئے کی تشکیل کا مسئلہ
ڈاکٹر صلاح الدین درویش
کہا جاتا ہے کہ انسان کی سب سے عظیم ترین دریافت زبان ہے جو کبھی تصویر کی صورت میں ہوا کرتی تھی،پھر تقریر کی صورت میں ترقی کرتی چلی گئی اور آخر میں تحریر کے فن نے زبان کے ذریعے انسانی عزم و ہمت کی طویل ترین تاریخ کو محفوظ بنانا شروع کر دیا۔یہی زبان قبائلی ،قومی اور ریاستی سطح پر وحدت کی علامت بننے کے ساتھ سیاسی، سماجی اور معاشی رابطہ کاری کے عمل کے ذریعے ان سب کے درمیان فکری روابط کو مؤثر بنانے کا باعث بنتی چلی گئی۔زبان کی اِس فکری بنیاد نے علوم کے مختلف شعبون میں مباحث و نظریات کے متنوع دفاتر کے انبار لگا دیے۔ علم کے ہر شعبے نے مختلف علوم کے دیگر مباحث و نظریات سے اِسی زبان ہی کے طفیل استفادہ کیا۔ یوں تمام علوم کے درمیان زبان ایک مضبوط ترین پُل کی صورت اختیار کرتی چلی گئی۔اِس حوالے سے زبان کی تاریخ کو بیان کرنا اِس مضمون کا مقصود نہیں ہے۔ ماہرینِ لسانیات اور اینتھراپالوجسٹ(Anthrapologist) اپنے بہترین تحقیقی مقالے دنیا کے سامنے پیش کر چکے ہیں۔ اِس مضمون میں صرف زبان کے ثقافتی مضمرات سے بحث کی جائے گی۔
ثقافت کسی قوم کے تمدنی اظہارات کا نام ہے۔ جس میں رسوم و رواج، میلے ٹھیلے،مذہبی عبادات کے طریقے،ادب و شعر کی دنیا، فنونِ لطیفہ،نشست و طعام کا سلیقہ، رہن سہن، آرائش و زیبائش کا ذوق، لباس، گھرداری سے لے کر کاروبار اور گلیوں محلّوں میں بسر ہونے والی زندگی کا مخصوص انداز سب شامل ہے۔ طبقاتی تنوع بھی اِسی ثقافت کے مختلف رنگوں کا اظہار ہوتا ہے۔ یہی اُصول شہری و دیہی زندگی میں ثقافت کے فرق کو بھی نمایاں کرتا چلا جاتا ہے۔ شہری...
The Qur’an is the most-read book in the world. Revealed by Allah Almighty to Prophet Muhammad, and revered by Muslims as being Allah’s Final Scripture and Testament, its words have been lovingly recited, memorized and implemented by Muslims of every nationality ever since. The Quran is also the only holy book that can be memorized in its entirety by people of all ages and intellectual abilities – including non-Arabic speakers – which Muslims consider to be one of its miracles. The Holy Quran is the source guide; the purpose of Similitude in Qur’an is to get a lesson. In each instance there is knowledge to mankind, it possesses a particular utility. Allah ta’aala has invited to all mankind to consider the Quran, as in the Holy Quran” Do they not then think deeply in the Qur'an, or are their hearts locked up (from understanding it)?”. This article explains deeply about the Importance of Similitude of Qur’an.
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.
