پروفیسر افغان اﷲ
یہ خبر افسوس ناک ہے کہ اردو کے ایک اور خدمت گزار پروفیسر افغان اﷲ خاں صاحب نے بھی اچانک آخرت کا رخت سفر باندھ لیا، ایک سمینار میں شرکت کے لیے انہوں نے دہلی کا سفر کیا تھا لیکن کیا خبر تھی کہ یہ اس دنیا کے آخری سفر کی تیاری تھی، سمینار کے پہلے روز وہ پورے نشاط کے ساتھ مختلف نشستوں میں شریک رہے، دوسرے روز دل میں درد اٹھا جس نے دنیا کے ہر دکھ سے ان کو نجات دے دی، وہ گورکھ پور یونیورسٹی کے شعبہ اردو کے صدر تھے، سکونت بھی اسی شہر میں تھی لیکن رہنے والے اصلاً وہ اعظم گڑھ کے ایک گاؤں خالص پور کے تھے شروع سے ذہین تھے، فراق گورکھ پوری پر جناب محمود الٰہی کے زیر نگرانی پی ایچ ڈی کی سند حاصل کی اور اس شان سے کہ موضوع پر یہ مقالہ خود سند بن گیا، کئی کتابیں سپرد قلم کیں، تاریخ ہند سے متعلق طراز ظہیری ان کی آخری تالیف تھی، باغ و بہار شخصیت کے مالک تھے، دارالمصنفین سے رشتہ اخلاص تھا، آخری بار وہ علامہ شبلی سمینار میں شرکت کی غرض سے یہاں آئے تھے، اتفاق ہے کہ مارچ کے معارف میں ان کا مضمون شائع ہوا، وہ ایک ہمدرد استاد، ہمدرد دوست اور ہمدرد انسان تھے، یو پی اردو اکیڈمی بھی ان کی سرگرمیوں کا مرکز تھی، گوشہ نشین اردو کے خادموں کی خدمت انہوں نے بے غرض ہو کر کی، صرف ۵۷ سال کی عمر میں ان کا اس طرح رخصت ہوجانا اردو کے لیے ہی نہیں، انسانیت اور شرافت کی دنیا کے لیے ایک بڑا حادثہ اور خسارہ ہے، خدا مغفرت فرمائے، آمین۔ ( عمیر الصدیق دریابادی ندوی ، اپریل ۲۰۰۸ء)
This paper is formulated under the conceptual framework of Gayatri spivak’s theory of Can Subaltern Speak? And explores the potential permeability of visual resources as a form of discourse through which subalterns found opportunity to counter media hegemony and make their voices heard. In order to analyze the selected graphic novel Munnu: A Boy From Kashmir (2015) the present qualitative study applies Grunter Kress and Theo Van Leeuwen’s model of visual design (2010) that connects the representational meaning to the interactive one. The analyst reflected upon how the interplay of visuals images and words together displayed the theme of Kashmir’s subjugation as well as how this genre has proved supportive to author to counter the said hegemony. Hence, the study found consent, political domination and media control as the broad elements that can be seen in the novel and also the study concludes that counter hegemony is possible through such literary genres, as the novel’s narrator has communicated those aspects of hegemonic situation in Kashmir to a large audience through literary discourse of graphic novel genre that are chiefly absent from mainstream media’s treatments of the Kashmir’s conflict. ______
Complete Coverage Path Planning (CCPP) is the process of finding a path that passes through all the accessible positions within the environment. CCPP is inherent to many real world robotic applications such as cleaning, agriculture, painting, lawn mowing, underwater operations, mine sweeping, search and rescue operations. The total operational time required for performing coverage is significantly influenced by total number of turns, optimization of backtracking sequence, and incorporating smoothness in the complete coverage path. A considerate amount of operational time is required by the backtracking sequence optimization algorithm in CCPP. The problem becomes evident when real world applications are involved. This thesis proposes two new methods to maximize coverage efficiency by first improvising current state of the art backtracking sequence optimization scheme and later generating smooth coverage path for feasible trajectory following by the robots. An efficient complete coverage path planning technique, online Boustrophedon using Two-way Proximity Search (B-TWPS) is proposed to minimize the total operational time, memory requirements and total coverage path length. The proposed algorithm first performs online boustrophedon motion until a critical point is detected. An intelligent backtracking point detection strategy is used, that efficiently detects all the backtracking points. The nearest point is selected as the next starting point by the algorithm. An optimal path from the critical point to the new starting point is computed using TWPS. The proposed online coverage technique is tested and validated in Matlab simulations. The proposed complete coverage path planning algorithm not only generated shorter complete coverage paths but also reduced the memory requiremens by 79.21% and total computational time requirements upto 97.49%. The current state of the art CCPP algorithms generate rectilinear coverage path comprising of straight lines with sharp turns. Such paths are infeasible for nonxi holonomic mobile robots, as the robot has to decelerate and reorient to follow the rectilinear path. A computationally efficient smoothness approach using rational conic Bezier spline is proposed. The proposed smoothness approach ensures ob- ´ stacle avoidance by automatically adjusting weight parameter. The proposed approach ensures suitable level of smoothness for slow speed non-holonomic mobile robots. The proposed coverage path smoothing algorithm reduced total coverage path length by 18.96% and total operational time upto 45.59% as compared to traditional rectilinear coverage path planning algorithms.
