منشی عبدالعزیز انصاری

منشی عبدالعزیز صاحب انصاری
دارالمصنفین کے خیر خواہوں اور خدمت گزاروں کو یہ خبر سن کر بڑا رنج و غم اور سخت ملال ہوا کہ اس کی مجلس انتظامیہ کے ایک معزز، سرگرم، مخلص اور قدیم رکن جناب منشی عبدالعزیز صاحب انصاری یکم دسمبر کو بمبئی میں وفات پاگئے، اِناﷲِ وَ اِنا اِلَیہ رَاجِعُون، یہاں سے ان کا تعلق حضرت مولانا سید سلیمان ندویؒ کے دور میں قائم ہوا، جو بعد میں محکم سے محکم تر ہوتا گیا، وہ بمبئی میں رہتے تھے، لیکن ان کا وطن اعظم گڑھ ہی تھا، اس لیے دارالمصنفین سے ان کا بڑا گہرا قلبی اور جذباتی تعلق تھا۔ اکثر کہا کرتے تھے کہ اس نے ہماری عزت و شہرت میں چار چاند لگادیا ہے، اس سرزمین پر وہ لوگ چلتے پھرتے دکھائی دیتے ہیں جنھوں نے اس کو علم و فن کا لالہ زار بنادیا ہے، وہ اس کی مجلس انتظامیہ کے جلسوں میں نہایت پابندی سے تشریف لاتے، ان کے قیمتی مشوروں سے دارالمصنفین کو بڑا فائدہ پہنچتا، مشکل وقتوں میں اس کے لیے سینہ سپر رہتے، دارالمصنفین کو مالی اعانت کی ضرورت ہوتی تو اس کے کارکنوں کو بمبئی ملاتے اور اپنے یہاں دعوتوں پر اصحاب ثروت کو مدعو کرکے اس کی امداد کرنے پر آمادہ کرتے، شبلی کالج سے بھی خاص تعلق رکھتے اور اس کی ترقی سے بڑی دلچسپی لیتے، تقریباً چالیس برس سے اس کی مجلس انتظامیہ کے صدر تھے، ان کا انتخاب ہمیشہ بلامقابلہ ہوتا تھا۔
ان کی رسمی تعلیم زیادہ نہ تھی، لیکن بڑے علم دوست اور اردو فارسی کا اچھا ذوق رکھتے تھے، وہ بمبئی میں ٹرانسپورٹ کا کاروبار کرتے تھے، جہاں ایک سے بڑھ کر ایک تاجر تھے مگر جو عزت، نیک نامی اور قدر و منزلت انھوں نے حاصل کی وہ کم کسی کو نصیب ہوئی، وہ مہمانوں کے لیے ہر...

صدقات جمع کرنے پر ریاستی پابندی کا اختیار پنجاب چیرٹیز ایکٹ 2018ء کے تناظرمیں تحقیقی مطالعہ

Early in 2018, Punjab Assembly passed a law in order to regulate welfare organizations and institutions. All welfare institutions were made bound to a complex official procedure. Violation of this procedure was regarded as a punishable crime. This law was widely discussed in think tanks and was strongly criticized. This research paper deals with understanding of this law, basic sections and their Islamic prespective is analysed according to Sharia. It has been proved in the light of Quran and Sunnah that Islam doesn't permit making non-obligatory charities system so complex and regarding it a crime. Hence, Government should make appropriate reforms in this law while reviewing it.

Stabilization of Nanholonomic Systems

The stabilization problem of nonholonomic systems, for many reasons, has been an active research topic for the last three decades. A key motivation for this research stems from the fact that nonholonomic systems pose considerable chal lenges to control system designers. Nonholonomic systems are not stabilizable by smooth time-invariant state-feedback control laws, and hence, the use of dis continuous controllers, time-varying controllers, and hybrid controllers is needed. Systems such as wheeled mobile robots, underwater vehicles, and underactuated satellites are common real-world applications of nonholonomic systems, and their stabilization is of significant interest from a control point of view. Nonholonomic systems are, therefore, a principal motivation to develop methodologies that allow the construction of feedback control laws for the stabilization of such systems. In this dissertation, the stabilization of nonholonomic systems is addressed using three different methods. The first part of this thesis deals with the stabilization of nonholonomic systems with drift and the proposed algorithm is applied to a rigid body and an extended nonholonomic double integrator system. In this technique, an adaptive backstepping based control algorithm is proposed for stabilization. This is achieved by transforming the original system into a new system which can be asymptotically stabilized. Once the new system is stabilized, the stability of the original system is established. Lyapunov theory is used to establish the stability of the closed-loop system. The effectiveness of the proposed control algorithm is tested, and the results are compared to existing methods. The second part of this dissertation proposes control algorithm for the stabilization of drift-free nonholonomic systems. First, the system is transformed, by using in put transformation, into a particular structure containing a nominal part and some unknown terms that are computed adaptively. The transformed system is then stabilized using adaptive integral sliding mode control. The stabilizing controller for the transformed system is constructed that consists of the nominal control plus a compensator control. The Lyapunov stability theory is used to derive the compensator control and the adaptive laws. The proposed control algorithm is applied to three different nonholonomic drift-free systems: the unicycle model, the front-wheel car model, and the mobile robot with trailer model. Numerical results show the effectiveness of the proposed control algorithm. In the last part of this dissertation, a new solution to stabilization problem of non holonomic systems that are transformable into chained form is investigated. The smooth super twisting sliding mode control technique is used to stabilize nonholo nomic systems. Firstly, the nonholonomic system is transformed into a chained form system that is further decomposed into two subsystems. Secondly, the second subsystem is stabilized to the origin using the smooth super twisting sliding mode control. Finally, the first subsystem is steered to zero using the signum function. The proposed method is applied to three nonholonomic systems, which are trans formable into chained form; the two-wheel car model, the model of front-wheel car, and the firetruck model. Numerical computer simulations show the effectiveness of the proposed method when applied to chained form nonholonomic systems. This research work is mainly focused on the design of feedback control laws for the stabilization of nonholonomic systems with different structures. For this purpose, the methodologies adopted are based upon adaptive backstepping, adaptive inte gral sliding mode control, and smooth super twisting sling mode control technique. The control laws are formulated using Lyapunov stability analysis. In all cases, the control laws design for the transformed models is derived first, which is then used to achieve the overall control design of the kinematic model of particular nonholonomic systems. Numerical simulation results confirm the effectiveness of these approaches.
