Minimum end-to-end delay, packet delay variations or packet jitter, and packet drop for given throughput in fixed and wireless networks are well-known important factors. These factors play important role in achieving better Quality of Service (QoS). Furthermore, these also have evident effects on network utilization, efficiency and better Quality of Experience (QoE) for services being carried over networks. Traffic intensities (TI) are generally used for dimensioning and capacity planning in telecom networks. Generally, TI depends on point of presence (POP) and its characteristics. These characteristics include type of area served, customer density, usage pattern and grade of service (GOS). Most of time, for TI in busiest hour is used to determine required capacities of network resources. This thesis research work extends concept of traffic intensity for period-to-period base rather than busiest hour and utilize traffic intensity being offered for packet scheduling in wireless and wired networks. This will provide an opportunity to manage packet forwarding decisions based on dynamics of planned Traffic intensities for given POP and will enable us optimize forwarding decisions and hence optimize delay, jitter, drop behavior of network nodes. To evaluate effects of packet scheduling based on TI, a model network was simulated using NS2 and Traffic Intensity Based Packet Scheduling (TIPS) algorithm was used to schedule packets from various sources to common destination. During analysis impact on end-to-end delay, jitter, and throughput and drop behavior of network nodes was evaluated and compared with various other available approaches. It is found that TIPS offers optimized results for better QoS and network utilization as compared to existing packet scheduling approaches like Drop Tail, Round Robin, Deficit Round Robin, RED and SFQ. This thesis document will provide details of packet scheduling methodology, TIPS algorithm, simulation results and their comparison with above packet scheduling algorithms.

تعارف ومنہج تفسیر تدبر قران

امین احسن اصلاحی نے تفسیر تدبر قرآن کا آغاز ۱۹۵۹ء میں کیا اور اس کی پہلی جلد ۱۹۵۶ء میں مکمل ہوئی۔نوجلدوں پر مشتمل یہ ضخیم تفسیر اگست۱۹۸۰ء میں پایہ تکمیل تک پہنچی۔ [[1]]

وہ تدبر قرآن کے مقدےمیں تفسیر لکھنے کے مقاصد بیان کرتے ہوئے تحریر کرتے ہیں:

"اس کتاب کو لکھنے سے میرےپیش نظر قرآن کریم کی ایسی تفسیر لکھنا ہے جس میں میری دلی آرزو اور پوری کوشش اس امر کے لئے ہے کہ میں ہر قسم کے بیرونی لوث اور لگاؤ کے تعصب و تخریب سے آزاد اور پاک ہوکر آیت کا وہ مطلب سمجھاؤں جو فی الواقع اور فی الحقیقت اس آیت سے نکلتاہے اس مقصد کے تقاضے سے قدرتی طور پر میں نے اس میں فہم قرآن کے ان وسائل و ذرائع کو اہمیت دی جو خود قرآن کے اندر موجود ہیں"۔[[2]]

امین احسن اصلاحی نےتفسیر تدبر قرآن کے تحریر کرنے میں اپنے استاد حمیدالدین فراہی کے اصول تفسیر و تدبر و تفکر کو بھی سامنے رکھا اور اپنی اس تفسیر کو انہوں نے ایک صدی کے تفکر و تدبر کا نتیجہ قرار دیاہے۔

تفسیر کے مقدمے میں تحریر کرتے ہیں:

"تفسیر تدبر قرآن پر میں نے اپنی زندگی کے پورے ۵۵ سال صرف کیے ہیں جس میں ۲۳ سال صرف کتاب کی تحریر و تسوید کی نذر ہوئے ۔ اگر اس کے ساتھ وہ مدت بھی ملا دی جائے جو استادامام ؒ نے قرآن کے غور و تدبر پر صرف کی ہے اور جس کو میں نے اس کتاب میں سمونے کی کوشش کی ہے تو کم و بیش ایک صدی کا قرآنی فکر ہے جو آپ کے سامنے تفسیر تدبر قرآن کی صورت میں آیا ہے"۔[[3]]

SINERGITAS PENGEMBANGAN KURIKULUM PAI DALAM PENDIDIKAN

Islamic education curriculum has central value for education process, as education vision direction. Islamic education mission is how to create religious people by leaning perfectly. Curriculum becomes one of success applications and quality in education institution most. Curriculum will develop based on global world and people life style existency. Therefore, education should view people life style increased as learning source that is becomed a value for curriculum step making. Beside that, islamic education curriculum development also becomes teacher’s choice to implement learning manner in class. In where, it’s implementation should be arranged and systematically to make maximal learning either in development vision, indicator, lesson teory, lesson model proccess, learning evaluation or teacher’s development skill. The process of islamic education curriculum development  must be done good and awesome also seeing several factors as supports and obstacles of it. In other to get an education result based on such the plan made before(education planning).

Leadership and Community Mobilization for Education Access to Marginalized Communities: the Case of an Ngo in Sindh, Pakistan

Education can uplift individuals, families and nations from poverty and enable their socio-economic mobility, and for that reason, achieving universal access to education has been included in several international and national memorandums. The United Nations, in 1948, declared education a basic human right. World’s leaders came together in Dakar (2000), then in New York (2015) and set the global ‎agenda for ensuring equitable education access for all. Generally, it is state’s responsibility to ensure education provision but sadly, the current education situation in Pakistan shows the bleak picture of government’s interventions and successes in the sector. For decades, Pakistan has faced serious challenges and setbacks to fulfill its promises on the above commitments, as around 22.6 million children are out of schools today. Non-government organizations (NGOs) have emerged as alternatives to help the government and communities to catch up and fulfill the local-global promises. Like the government, NGOs have also been contested in the literature between being solution and problem to providing affordable, relevant, quality and sustainable education to the marginalized communities. Against these local-global realities and theorizations, this qualitative case study explored how a local educational NGO, through its leaders’ thoughts and actions mobilized underprivileged communities to increase their children’s access to quality education. The study’s findings are consistent in describing NGO’s and its schools’ positive role in making education accessible. It is found that providing education access in the economically deprived, religiously fragile and politically charged conditions of rural Sindh demand more complex, creative and yet contextualized approaches. The NGO (AAS, pseudonym) and its schools considerably expanded access of quality education to the public through the clear policy-practice match in maintaining standard education, social mobilization, inclusiveness, subsidized-fee and social capacity-building projects. Apart from these, (a) the schools’ proximity, (b) excellent infrastructural facilities, (c) safe learning environment, (d) educational opportunities and (e) committed local female teachers, -- all improved access, quality, sustainability, relevance and community’s emotional engagement and advocacy of the schools. An important finding was the establishment of schools’ direct relationships with communities and individuals instead of using specially designed structures like school management committees. Community mobilization took place and sustained due to highly committed and culturally informed NGO’s and schools’ leadership. They aligned their organizational mission and policies with the contextual nuances. As a result, schools’ interventions were not seen a threat to local traditions and norms. AAS’s schools accomplishments to reach out poor families ultimately depended
