عبداللطیف اعظمی کی وفات
(سبط محمد نقوی)
آج ۱۸؍ مئی کو لکھنؤ کے ایک اردو روزنامے میں رضا لائبریری رامپور میں منعقدہ ایک تعزیتی جلسے کی کاروائی نظر سے گزری، اس میں تین ادیبوں کی وفات پر اظہار غم دالم کیا گیا ہے۔ ان میں سے ایک نام محب محترم عبداللطیف اعظمی صاحب مرحوم کا بھی ہے۔ ان کے ایسے مستند دانشور کے فقدان کا جو صدمہ ہوا وہ اپنی جگہ پر ہے۔ اس کا ملال مستزاد ہے کہ وہ بہت چپ چپاتے رخصت کردیئے گئے۔ ریڈیو پر بھی یہ خبر اذیت اثر سننے کو ملی۔ لکھنؤ کے ان تین اردو اخباروں میں نظر سے گزری جو ہمارے یہاں آتے ہیں۔
مرحوم جامعہ ملیہ اسلامیہ کے انتظامی عملے میں تھے لیکن تعلیمی دور سے لے کر سبکدوشی کے بعد تک مرحوم کا قلم گل افشاں رہا۔ مولانا شبلی نعمانی مرحوم کے دفاع میں ان کا جہاد اور ماہنامہ جامعہ کے احیاء میں ان کی سعی مشکور۔ ان کے عدیم النظیر تاریخی کارنامے ہیں۔
مرحوم سے ملاقات کے موقع تو بس تین چار بار آئے مگر خط و کتابت کافی رہی۔ آخر میں میرے کسی فقرے سے بددل ہوکر مراسلت کا سلسلہ قطع کردیا تھا، پھر بھی کسی بات کے سلسلے میں ہیچ مداں کے معلومات جاننا چاہے تھے تو یاد فرمایا تھا۔
مجھے نہایت خوش اخلاق، مہمان نواز اور کریم النفس انسان لگے۔ ان سے آخری ملاقات جب ہوئی تو برادرم ضیاء الحسن فاروقی صاحب بھی وہیں تشریف فرما تھے۔ یہ ملاقات ان دونوں حضرات سے آخری تھی۔ افسوس ہے کہ وہ نسل بھی اب اٹھتی جاری ہے، جس نے بزرگان پیشیں کے دور کا ادراک کیا تھا۔ میں ان دونوں کے لئے دعائے مغفرت کرتا ہوں۔ فقط والسلام: سبط محمد نقوی۔ ( جون ۲۰۰۲ء)

The Big Shift: Examining Practices, Challenges, and Coping Mechanisms of Teachers and Students in Transitioning to Modular Distance Learning

In response to the COVID-19 pandemic threat, the Department of Education (DepEd) established the Basic Education - Learning Continuity Plan (BE-LCP) to allow students to continue their education and teachers to conduct instruction in a safe working and learning environment. As a result, DepEd implemented the distance learning approach, including Modular Distance Learning (MDL), for the School Year 2020-2021. This paper investigated the practices, challenges, and coping mechanisms of teachers and students involved in the implementation of the MDL in Schools Division of Laoag City. This qualitative research utilized semi-structured interview guide to collect data from 20 teachers and 20 learners from elementary, junior high and senior high schools. Using the phenomenological study, data were analyzed and organized into themes. The study's major themes revealed that teachers and students began familiarizing themselves with the features of MDL but encountered challenges such as printing, distribution, and retrieval of modules, as well as monitoring of student progress on the part of the teacher and answering overloaded activities on the part of the students. They claimed, however, that they have unique coping mechanisms in dealing with the identified challenges by resolving issues independently and seeking help from family and colleagues. Finally, the Modular Distance Learning Adoption Framework (MDLAF) was developed and validated for teachers and students to effectively adopt MDL. The researchers recommended that relevant scaffolding such as capacity building, counseling and instructional support be provided to both teachers and students to effectively adopt different learning modalities such as MDL.

Q O S Optimization Through Capacity Aggregation of Multiple Links in Heterogeneous Wireless Networks

Wireless and mobile networking is considered as the most appreciated technologi- cal innovation that has stormed into the life-styles of the people and has found applica- tions in business, education, health, social networking and all other major areas of day-to- day work. Inspired by the enormous potential of mobile computing, wireless communica- tion and mobile networking technologies have emerged as major research disciplines within the domain of communication systems. Most of the communication based applica- tions have been developed and executed on robust wired communication networks and when they are ported to mobile devices, face serious challenges in meeting quality of ser- vice (QoS) requirements over the mutable wireless media. The QoS enabling for mobile networks has, therefore remained a major research area in this discipline. The presence of multiple communication interfaces in modern multi-mode mobile devices has enabled a new dimension for improving QoS solution during mobility but the heterogeneity of these networks pose serious challenges for delay bounded QoS aware applications. In this the- sis, capacity aggregation (CAG) of multiple available wireless links has been investigated to quantify its suitability in providing QoS during mobility. There are numerous challenges faced by the designers and developers in synchro- nizing flows, transported over multi-path. One such issue is the out-of-sequence (OOS) reception of packet at the receiver due to transport of these packets on multiple heteroge- neous paths. The larger extent of OOS receptions; generally cause serious performance degradation in delay bounded real-time applications, and is also a source of expensive buffer management for in-order delivery of packets to their respective destinations. The problem gets adverse during mobility, as the end-to-end path repeatedly changes during mobility and accompanies with changes in characteristics of E2E path that enhances probability of OOS reception. Therefore, maximization of QoS through minimization of OOS reception in a CAG environment is the main problem investigated in this thesis. The problem has been persuaded with novel multi-server scheduling schemes that minimize the OOS reception at the receiver. The proposed multi-server scheduling schemes provide a general service model that accommodates multiple types of traffic flows belonging to different classes-of-service. This approach is in contrast to the QoS maximization of a single flow at upper layers of TCP/IP protocol stack. The approach of multi-server scheduling to minimize OOS reception has been in- vestigated with the help of novel deterministic and stochastic analytical models to provide quantified solution of the above given problem. The fundamental mathematical structure of novel deterministic and stochastic models has been elaborated to enumerate multi-path transport dynamics of a mobile flow. These models provide appropriate formulae for the dimensioning questions of the QoS during mobility. Hence, the analysis of the multi-path transport of mobile flows remains as the main focus of this research work and constitutes core of this dissertation. Since the deterministic and stochastic framework for the analysis of E2E multi-path dynamic are not fully developed, my research focused on efficient es- timations of E2E delay variations and its impact on OOS reception of packets. The tight deterministic and stochastic performance bounds have been derived through proposed models. The main application of these models has been exercised in development of suit- able scheduling strategies that minimize E2E delay variation and OOS reception in CAG during mobility. The results of proposed models have been validated through simulations ‐v‐ as well. The results have shown robust performance of proposed scheduling schemes in achieving acceptable QoS levels for real-time flows during mobility, with minimized OOS reception and reduced buffer occupancy.
