کہانی پڑھی جارہی ہے
(سید ماجد شاہ)
چوک میں جہا ز کی ڈمی نصب کی جا چکی تھی۔لڑکی نے چوک سے یو ٹرن لینے کے لیے ،گاڑی کی رفتار آہستہ کی ۔جب گاڑی چوک سے نیم دائرہ بنا کر مڑ رہی تھی تو فرنٹ سیٹ پر بیٹھے ، لمبے بالوں والے لڑکے نے کہا،‘‘ میں ایک منتر نما ایکویشن سے یہ جہاز اڑا سکتا ہوں۔
لڑکی نے کنکھیوں سے دیکھا جہاز آدھا پینٹ کیا جاچکا تھا۔
لڑکی، جس کے جسم میں جاری تمام کیمیائی عمل بحالتِ اعتدال کام کر رہے تھے ،جیسے ایک بیس بائیس سال کی مائل بہ فربا خوشحال گھرانے کی لڑکی میں کام کرتے ہیں۔
اس نے لڑکے کی کپکپاتی مخروطی انگلیوں کو غور سے دیکھا، جن پر سگریٹ کے سرمئی داغ ، تیز گندمی رنگ پر نمایاں تھے۔پھر لڑکی نے بائیں ہاتھ سے اپنی سرخ ٹی شرٹ کا بٹن کھولتے ہوئے پورے یقین سے کہا، ‘‘ میں اس پر اڑنا چاہوں گی۔’’
گاڑی کا اے سی بند تھا ۔ شیشے تھوڑے نیچے کیے گئے تھے تاکہ سگریٹ کا دھواں خارج ہو سکے، اس عمل سے دھواں باہر ضرور نکل رہا تھا لیکن رد ِ عمل کے طور پر باہر کی شدید گرمی گاڑی میں بھر گئی تھی۔
جب لڑکی یہ جملہ بول رہی تھی۔‘‘ میں اس پر اڑنا چاہوں گی۔’’تو اس کے لہجے میں مذاق کا عنصر رائی برابر بھی شامل نہیں تھا، کیونکہ جب وہ مذاق کے موڈ میں ہوتی تھی تو اس کی آنکھوں میں شرارت کی لہر ابھر کر بھوؤں کو کمان بنا دیتی اور کمانیں ماتھے پر لطیف شکنیں پیدا کردیتیں۔ اس پر ہونٹوں کے ابھار میں اضافہ اور گالوں کے تھوڑا اٹھ جانے سے اس کا...
Child labor has been considered the most troubling & one of the greatest problems of great concern in the modern world, since it has not only negative effects on the child himself, but also on his family & society in general. However, it is a reality that can commonly & frequently be observed in the emerging & backward nations now a day where expropriated & evicted people take their young ones to workplaces to compete with their livelihoods. This article seeks to highlight the status of child labor & its solution in the light of Qur᾽an & Sunnah as many experts and platforms have offered their own solution. The study population consisted of scholars &the teachers/A᾽ema Kerām of religious institutions (Madrasah) of the Khyber Pakhtunkhwa Bannu, while its sample included 30 scholars & teachers/A᾽ema of different Madrasah in the Bannu District. The researcher has adopted content & methodologies of the interview from the respondents to explore this issue in detail. This study has the sole objective of: to find out solution of the Child Labour in the light of Holy Qur᾽an & Sunnah. This article summarizes the conclusion that holy religion of Muslims(Islam) strictly prohibit child labour, although allows child labour in some special cases, such as light work & character building activities which is
Power Efficient Resource Allocation in High Performance Computing Systems An efficient resource allocation is a fundamental requirement in High Performance Computing (HPC) systems. Many projects are dedicated to large-scale distributed computing systems that have designed and developed resource allocation mechanisms with a variety of architectures and services. Resource allocation mechanisms and strategies play a vital role towards the performance improvement of all the high performance computing classifications. Therefore, a comprehensive discussion of widely used resource allocation strategies deployed in distributed high performance computing environment is required. The author has classified the distributed high performance computing systems into three broad categories, namely: (a) cluster, (b) grid, and (c) cloud systems and defines the characteristics of each class by extracting sets of common attributes. All of the aforementioned systems are cataloged into pure software and hybrid/hardware solutions. The system classification is used to identify approaches followed by the implementation of existing resource allocation strategies that are widely presented in the literature. More computational power is offered by high performance computing systems to cope with CPU intensive applications. However, this facility comes at the price of more energy consumption and eventually higher heat dissipation. As a remedy, these issues are being encountered by adjusting system speed on the fly so that application deadlines are respected and also, the overall system energy consumption is reduced. In addition, the current state of the art of high performance computing, particularly the multi-core technology opens further research opportunities for energy reduction through power efficient scheduling. However, the multi-core front is relatively unexplored from the perspective of task scheduling. To the best of our knowledge, very little is known as of yet to integrate power efficiency component into real-time scheduling theory that is tailored for high performance computing particularly multi-core platforms. In these efforts the author first proposes a technique to find the least feasible speed to schedule individual tasks. The proposed technique is experimentally evaluated and the results show the supremacy of our approach over the existing counterpart called first feasible speed. However, this solution is at the cost of delayed response time. The experimental xi results are in accordance with the mathematical formulation established in this work. To minimize power consumption, the author did another attempt by applying genetic algorithm on first feasible speed. The newly proposed approach is termed as genetic algorithm with first feasible speed. The author compares the results obtained through aforementioned approach with existing techniques. It is worth mentioning that proposed technique outperforms first feasible speed and least feasible speed with respect to energy consumption and response time perspectives respectively. Load balancing is also vital for efficient and equal utilization of computing units (systems or cores). To load balancing among computing units, the author applies lightest task-migration (task-shifting) and task splitting mechanisms in a multi-core environment. In task shifting a task having minimum load on a highly utilized computing unit is fully transferred to a low utilized computing unit. In task splitting, the load of a task from a highly utilized computing unit is shared among the computing unit and a low utilized computing unit. It concludes from the given results that task splitting mechanism fully balance load but it is more time consuming as compared to task shifting strategy.
