The usage of multimedia applications is growing and the requirements for higher quality content delivery are increasing rapidly in the mobile network environment. The mobile network environment is challenging for recent multimedia applications as compared to the wired network environment in various ways. The multimedia contents are delivered to mobile users over heterogeneous networks. Due to fluctuation in bandwidth and user mobility, the service providers are facing difficulties in providing Quality of Service and guaranteed content delivery for multimedia applications. The existing schemes use the single source and multi-source delivery but are unable to balance between stream quality and network congestion for mobile users. Recently, HTTP is used for video streaming that ensures persistent integration of video quality to current HTTP based servers. The HTTP server stores multiple quality levels to provide adaptive media streaming under varying network environment. We designed a Quality Oriented Multimedia Content Delivery Scheme for the mobile cloud to deliver better quality multimedia contents for the mobile user. A method is developed to measure smooth available bandwidth in varying network condition that is used for bitrate selection. An optimized rate adaptation algorithm is designed and implemented to select the best bitrate for the next video chunk.The multimedia contents are delivered to the mobile device on the basis of the device’s parameters and network environment. A rate adaptation algorithm is designed by using Lyapunov optimization for multisource multimedia content delivery to minimize the video rate switches and provide higher video quality. The mobile cloud based multi-source streaming is designed and implemented to enhance performance in an adaptive video streaming client. The performance is compared with existing streaming techniques to validate the multi-source streaming solution. It considers key factors such as video quality, bitrate level, and quality variations to enhance quality of experience over wireless networks. The objective video quality assessment models like Peak Signal-to-Noise Ratio, Structural Similarity, and Video Quality Measurement are used to measure quality of the video. The client side Quality of Experience metric such as Startup delay, Rebuffering events, and Bitrate switch count are used for evaluation. The results show significant improvement over existing multimedia content delivery schemes.

مولانا امین احسن اصلاحی

مولاناامین احسن اصلاحی
۱۶؍ دسمبر ۱۹۹۷؁ء کو جامعۃ الفلاح بلریا گنج میں یہ اندوہ ناک خبر سنی کہ مولانا امین احسن اصلاحی صاحب کی وفات ہوگئی، اناﷲ وانا الیہ راجعون۔
ادھر سال بھر سے اس کا کھٹکا لگا ہوا تھا کہ علم و کمال کا یہ مہر جہاں تاب غروب ہونے والا ہے۔ اور قرآن و حدیث کے بحر کا شناور اور غواص، علامہ حمید الدین فراہیؒ کا جانشین و ترجمان، ان کے علوم و معارف کا وارث و امین، حکمت قرآنی کا شارح و مبین، دین حق کا داعی و مبلغ، اسرار دین کا عارف و آشنا، شرک و توحید اور تقویٰ و نماز کا رمزو حقیقت شناس اپنے ہزاروں شاگردوں اور قدردانوں کو مغموم، اداس اور سوگوار چھوڑ کر جلد ہی سفر آخرت پر روانہ ہونے والا ہے۔
ابھی مولانا بدرالدین اصلاحی ناظم مدرستہ الاصلاح و دائرہ حمیدیہ کا غم تازہ ہی تھا کہ مدرسہ کا یہ گل سرسبد اور فکر حمید کا سب سے بڑا حامل و شیدائی بھی رخصت ہوگیا۔
کیا کہوں تاریکیٔ زندانِ غم اندھیر ہے
پنبہ نورِ صبح سے کم جس کے روزن میں نہیں
مولانا امین احسن اصلاحی صاحبؒ اعظم گڑھ شہر سے پورب میں واقع ایک گاؤن ’’بمہور‘‘ کے متوسط زمیندار گھرانے میں ۱۹۰۳؁ء میں پیدا ہوئے تھے۔ ان کے والد حافظ محمد مرتضےٰ صاحب ایک دیندار، متبعِ سنت اور تہجد گزار شخص تھے، وہ اپنے فرزند کو دینی تعلیم دلانا چاہتے تھے، اپنی اس تمنا کا ذکر انھوں نے اپنے ہم وطن دوست مولانا شبلی متکلم ندوی سے کیا جو علامہ شبلیؒ کے عزیز شاگرد اور مدرستہ الاصلاح سرائے میر کے منصبِ اہتمام پر فائز تھے۔ انھوں نے اسی مدرسہ میں مولانا امین احسن صاحب کا داخلہ کرادیا، جہاں انھوں نے ان سے اور دوسرے اساتذہ سے دینی علوم کی تحصیل کی، ان کو اپنی طالب علمی کے...

فکر روایت اور تصوف: مغرب میں تصوف کے فروغ میں فکر روایت کا حصہ اور پاکستان کے اردو ادب پر اثرات

Islam and Mysticism or tasawuf have coexisted. Sufism has flourished in all Muslim dominated regions. Sufism is a mode of spirituality within Islam. Sufi schools teach three parts: Shariah, Tariqah and Haqiqh. In this article, traditional thoughts in Sufism and its impacts on the world especially in the region of Indo-Pak have been discussed. The shrines of Pakistani Sufis are the centers of inspiration for mysticism and spirituality that influence cultures and civilizations.

Smart Grids: Channel Modeling for Nb-Plc

Future electricity power network must be restructured to improve its e ciency in order to provide all the consumers with exible, cost e ective, reliable and accessible power delivery. Power Line Communications (PLC) is a vital part of Information and Communication Technologies (ICT) within the smart grid (SG). This thesis presents the analysis and modeling of Low Voltage (LV) transmission lines for Narrowband Power Line Communications (NB-PLC) by incorporating the approach of transmission line (TL) theory and developing its Simulink model followed by their results discussion. The thesis also presents the comprehensive eld measurements based analysis which provides a generalized NB-PLC channel model for LV access network in order to deploy Advanced Metering Infrastruc- ture (AMI) within Lahore, Pakistan. This is therst time, such kind ofeld measurements have been carried out in Pakistan. Selective sites foreld mea- surements that include GaddaStadium, Hafeez Center, Kot Lakhpat, Lahore Cantt, Ghaziabad, Township, Wapda Town, Valencia Town and Defense Housing Authority (Phase-V) were allocated by LESCO which took into account all classi - cations of load types within Lahore city. Theeld measurements of allocated sites were performed in the residential (urban and rural), industrial and commercial electricity consumers for the NB-PLC channel modeling of low voltage overhead transmission lines (TLs). On the basis of extensiveeld measurement results, the average attenuation pro le and transfer functions (TFs) are presented. A Simulink model is developed to validate the results obtained fromeld measurements. The analyses of measured and simulated results illustrate a close agreement of channel TFs. This research work proposes an improved, more e cient, and more accurate NB-PLC channel model especially for South Asian countries.
