ایم مہدی حسن افادی الاقتصادی
ماہ گزشتہ میں ایم مہدی حسن (افادی الاقتصادی) کا انتقال ادبیات اردو کے لئے ایک سخت حادثہ ہوا، مرحوم ایک سحرنگار ادیب اور ایک خاص طرزِ انشاء (اسٹائل) کے موجد تھے، معارف کے افق پر یہ برق ایک سے زائد بار چمکی اور یقین ہے کہ ناظرین کے دلوں میں ’’شبلی سوسائٹی اور معاصرانہ چشمک‘‘ کے لکھنے والے کی یاد ابھی بالکل تازہ ہوگی، مرحوم کو مولانا شبلی کی ذات سے گہرا تعلق تھا، اسی لئے وہ معارف کو بھی بہت عزیز رکھتے تھے اور دارالمصنفین کی مجلس انتظامی کے رکن تھے، ادب و انشاء کا ایسا ذوقِ سلیم رکھنے والے افراد مدتوں میں پیدا ہوتے ہیں۔ افسوس ہے کہ ۲۲؍ نومبر کو یہ ماہتاب کمال پیوند خاک ہوگیا۔ اِنَّالِلّٰہِ وَاِنَّا اِلَیْہِ رَاجِعُوْنَ۔
گورگھ پور وطن تھا، مشرقی تعلیم کے ساتھ انگریزی تعلیم حاصل کی تھی۔ قرق امینی سے تحصیلداری تک بتدریج ترقی کی تھی۔ نہایت مہذب اور سنجیدہ تھے، مزاج میں نفاست اور لطافت حد درجہ تھی۔ (سید سليمان ندوی، دسمبر ۱۹۲۱ء)
اردو کے لطیف انشا پرداز ایم مہدی حسن مرحوم (افادی الاقتصادی) کی یاد اب تک ان کے قدردانوں کے دلوں میں باقی ہوگی، مرحوم کی زندگی کی خالص خصوصیت لطافت پسندی تھی، جس سے ان کی زندگی کا کوئی شعبہ خالی نہ تھا، رہنا سہنا، پہنا اوڑھنا، پڑھنا لکھنا، سفر اور قیام، خیال اور تصور، تحریر اور تقریر ہر شے میں ان کی یہ خصوصیت نمایاں تھی، مولانا شبلی مرحوم کے لٹریچر کے وہ شیدا تھے، وہ ڈھونڈھ کر عمدہ سے عمدہ لفافے اور کاغذ مولانا کے پاس بھیجتے تھے کہ وہ ان پر ان کو خط لکھیں، جب دارالمصنفین سے کتابیں منگواتے تھے تو فرمائش ہوتی تھی کہ کتاب کی...
Arabian Peninsula was famous for its language expertise and linguistic expressions at the time of Prophet Muhammad (ﷺ). The poets and language experts would spend most of their lives to attain excellence in Arabic language and literature. It was during such time that a man named Muhammad (ﷺ) emerged, whose linguistic expression was remarkable, accurate and amazing. He was also quite familiar with the dialects and accents of every tribe of Arabia. It was the surprising effect of this linguistic excellence that people tagged him with different titles such as Poet, Sorcerer, Kāhin (soothsayer), Majnūn (One possessed by Jinn), and insane man with insane message. Allah Almighty revealed Qur’ānic verses not only to answer such allegations but also entrusted him to present commentary of the Holy Qur’ān to the people who would called him illiterate. This article will try to find out the Qur’ānic commentary on the linguistic expressions of Prophet Muhammad (ﷺ) as a miracle of revelation. The method of research is descriptive analytical and historical. The discussion of verses of Qur’ān and the explanations of the experts of Qur’ān through the comments of orientalists have been included to support the arguments. First Part of the paper discusses status of Prophet Muhammad (ﷺ) as an illiterate man with his remarkable linguistic expressions of Qur’ān due to which he was awarded different titles such as poet, sorcerer and insane. The second part explains the Qur’ānic response to accusations on Prophet (ﷺ) raised by the opponents. In the third part, some intellectual arguments of Qur’ān and opinions of orientalist have been discussed to support the Qur’ānic responses in favor of linguistic expressions of an “Ummi” Prophet Muhammad (ﷺ) which is followed by findings and conclusion of the whole discussion.
With the growing electricity demand and environmental challenges, integration of the high penetration distribution generation (DG) into the utility grid is utmost important to improve the grid efficiency. Microgrid helps in facilitating the penetration of various DGs in the distribution network, while ensuring efficient, reliable and resilient operation in an islanded mode during a utility outage. However, the power electronic interface with DG units needs robust control techniques that can achieve high performance in all the loading conditions and conditions at the utility grid. Microgrid contains a cluster of loads along with DG units operating as a unified controlled system. Interconnecting DGs with a grid using power electronic converters has increase concerns regarding safe operation and protection of the equipment. Many control strategies have been proposed for enhancing the stability of microgrid for proper load sharing. However, these controllers have problems of slow dynamic response, disturbance to uncertainties and weak tracking of the references. Therefore, this work proposes new approaches using nonlinear control technique based on the sliding mode control (SMC) for an islanded mode as well as grid-connected mode of operation. Fixed Frequency Sliding Mode Voltage Control (FFSMVC) technique is developed for single and parallel voltage source inverter (VSI) in islanded mode, to maintain the quality of the output voltage of the DG system despite unbalanced and/or non-linear load currents. Fix frequency slide mode control is efficient in reducing the chattering phenomena, which otherwise call unnecessary harmonics and power loss in the system. Further, this controller improves the steady state and dynamic response under sudden load fluctuation. Droop control approach is investigated to guarantee the accurate power sharing among DG units in parallel operation. Fixed Frequency Sliding Mode Current Control (SMCC) approach is adopted for the grid-tied mode, where the controller works as a current controller. The proposed controller effectively abandons the grid voltage disturbances and the parameter uncertainties. Furthermore, PQ sharing control is designed for the parallel operating of DG units by delivering available power to the grid side in order to ensure power-sharing requirements. Both controllers have been simulated in the real-time domain of Simulink/MATLAB environment. Finally, the performance of the proposed FFSMC is compared with the classical proportional integral (PI) controller. The simulation results show the Total Harmonics Distortion (THD) of the output voltage of 0.86% and 1.54% for FFSMVC, and 1.82% and 6.84% for PI controller under linear and nonlinear loads respectively. The results also validate that the proposed control technique is quite effective due to its robust response and less sensitive to external disturbances.
