ایاز اصغر شاہینؔ(۱۹۴۳۰ء) ڈسکہ میں پیدا ہوئے ۔۱۹۶۶ء میں ایم۔ا ے اردو کیا اور ۱۹۸۳ء میں گورنمنٹ کالج شکر گڑھ میں اردو لیکچرا ر تعینات ہوئے۔ ادبی زندگی کا آغاز نویں جماعت سے ہوا۔ اصغر شاہین نے سیالکوٹ میں کئی طرحی اور غیر طرحی مشاعروں میں حصہ لیا۔ (۹۹۸) اور اپنے فن کے جوہر دکھائے۔
ان کا شعری کلام مختلف ادبی رسائل وجرائد میں شائع ہوتا رہا۔ اب تک ان کا کوئی شعری مجموعہ طبع نہیں ہوا۔ شاہینؔ غزل اور نظم کے شاعر ہیں۔ ان کی شاعری میں تغزل کا عنصر نمایاں ہے۔ غزل ہو یا نظم، حمد ہو یا نعت، قطعہ ہو یار باعی ،قصیدہ ہو مرثیہ ہر صنف سخن میں وہ سوزِ دروں کو شامل کر کے اس فن پارے کو امر کر دیتے ہیں۔ ان کا ایک ادبی کارنامہ یہ ہے کہ انھوں نے قرآن مجید کے مختلف پاروں کا منظوم اردو ترجمہ کیا ہے۔ اس کے علاوہ بیـشتر احادیث اور متفرق آیات کا بھی منظوم ترجمہ کر کے اپنی قادر الکلامی کا ثبوت دیا ہے۔ ان کی شاعری کا اہم موضوع عشق حقیقی ہے۔ شاہین ؔکا نمونہ کلام ملاحظہ ہو:
نام سے ہے اس خدا کی ابتدا
7مہرباں بے حد رحیم اس کی ثنا
5بس خدا کی ذات ہے اس کے سوا
9کوئی ہو سکتا نہیں ہرگز اِلہٰ
1ہے میسر اس کو دائم زندگی
اونگھ نیند آتی نہیں اس کو کبھی
آسمانوں میں زمیں میں جو بھی ہے
;اس کی ملکیت میں ہے ہر ایک شے
The Internal dissensions within the ranks of the Muslim Ummah are very harmful and condemnable. Today, the Muslims of the world have fallen into the deep recesses of decline due to their mutual differences. The intrigues and conspiracies of the hostile nations have created schism and dissensions among the Muslims on the grounds of language, land, race and color. In our country (Pakistan), if we ponder on the growing rate of violence, we will find that the main causes of this chaos are our attitude towards our mutual differences. Because of intolerant approach towards our mutual differnces, our difficulties and problems are sizing up, and they have engulfed the whole nation, now. The only point on which our nation can be united is the “Kalimah”. The followers of this “Kalimah” whether they are white or black, rich or poor, or whatever race they belong to, and whatever territory or country they come from, they are all considered as the member of the Muslim Ummah. Keeping the prevailing situation of the Muslim Ummah, the author of this paper feelss that an appropriate answer to the question, ‘are all sorts of differences condemnable?’, is key to end most of our differences. In fact, all sorts of differences are not condemnable or forbidden; if differences of opinions are based on some logical grounds within the jurisdiction of the Qur’ān and Aḥādīth, they are permissible and justified as inevitable and natural. Such kind of approach can promote tolerance and unity among the Muslim Ummah and can put us at peace.
Robots are playing quite a useful role in many industries. In nuclear industry, robots protect radiation workers from receiving radiation doses while working in highly active areas. They also improve the quality of work and demonstrate profitability in nuclear industry. The aim of this project was to design and develop a Radiation Protection Assistant Robot (RPAR) for assisting radiation workers in a radioactive environment for routine work as well as in emergency situation. During an emergency situation, where higher doses are likely to be received, RPAR can be used effectively to perform various tasks, such as radiation mapping, sampling and handling radioactive waste/materials. To accomplish these tasks a mobile robot having 4 Degree-Of-Freedom (DOF) articulated robotic arm was designed and developed using locally available components and indigenous resources. The mechanical segments, i.e. gripper, wrist, elbow, shoulder and waist were developed at Pakistan Institute of Engineering & Applied Sciences (PIEAS) and Pakistan Institute of Nuclear Science & Technology (PINSTECH). The main platform was developed to carry on-board computer, rechargeable battery, controlling electrical and electronics modules/circuits. The electronic modules have been developed using components available in local market. These modules include H-bridge, relay logic, parallel port interface and limit switch modules. Control panel and remote console are developed to control and operate the RPAR. An embedded controller card was also developed to determine the positions of various links of RPAR. RPAR weighs 55.6 kg. It is powered by a 12 V DC rechargeable dry battery. Its maximum payload capacity and reach are 2.1 kg and 1.04 m, respectively. It can be controlled by a wired remote control or an off-board PC via wireless Ethernet. Three Software namely RPARSOFT, RPAR-DEMO and SEDAS were designed and developed using Visual Basic 6.0. RPARSOFT was developed to operate the RPAR from the keyboard of an off-board computer. The RPAR- DEMO was developed to self check the electrical and electronic modules of RPAR, whereas, SEDAS was designed for the embedded controller card to determine the real time position of wrist, elbow, shoulder and waist of RPAR. Kinematics studies, Dynamics analysis, manipulator Jacobian and work space analyses were performed to study the performance and range of the robot. Repeatability range and payload capacity of RPAR was measured. Radiation hardening study has also been carried out to check the stability and reliability of the commercial components in the field of gamma radiation. The modules were found working satisfactorily before and after irradiating them up to a dose of 9 Sv. The objectives have been achieved successfully.
