مولانا ضیاء الدین احمد بدایونی
افسوس ہے کہ گذشتہ جولائی میں ایک ممتاز علمی شخصیت مولانا ضیاء احمد بدایونی سابق صدر شعبہ فارسی مسلم یونیورسٹی نے وفات پائی ، مرحوم فارسی زبان کے فاضل اور مسلم الثبوت استاد تھے، انہوں نے فارسی کی درسیات پرانے طرز پر پڑھی تھیں اور عربی سے بھی واقف تھے، اس لیے فارسی زبان و ادب پر ان کی نظر ماہرانہ تھی، ان کا ذوق بڑا متنوع تھا، مذہبیات اور تاریخ اسلام سے بھی ان کو دلچسپی تھی، اور ان سب پر ان کے مضامین اور تصانیف موجود ہیں، ان میں سب سے اہم دیوان مومن کی شرح اور اس کا فاضلانہ مقدمہ ہے اور یہ کہنا صحیح ہوگا کہ جس طرح سب سے پہلے ڈاکٹر عبدالرحمن بجنوری نے کلامِ غالب کی اہمیت نمایاں کی تھی، اسی طرح مولانا ضیاء احمد نے مومنؔ کے کلام کی اہمیت واضح کی، وہ عملاًنہ صرف دیندار بلکہ خوش عقیدہ مسلمان تھے، جس کا اثر ان کی تمام مذہبی تحریروں میں ہے، اس زمانہ میں جب کہ فارسی کا ذوق گھٹتا جا رہا ہے مرحوم کی جگہ مشکل سے پُر ہوسکے گی، اﷲ تعالیٰ ان کی مغفرت فرمائے۔ (شاہ معین الدین ندوی، ستمبر ۱۹۷۳ء)
Japan and the land of present Pakistan had cultural linkages since ages. Sindh has remained important part of this land. The Indus civilization had trade links with other countries including Sumerian and Babylonian civilizations. This trend continued afterwards, and trade relations were established between people of Sindh and Japan in the nineteenth century. This interaction led both the countries to have cultural linkages. Presently many Sindhis are residing in Japan who have adopted Japanese culture besides maintaining their own cultural traditions and customs. Sindhi poetry adopted Japanese Haiku and ‘Safarnamas’ were written in Sindhi language grasping the living and traditions, etc. Of Japan. This research paper also discusses that both countries’ people have similar style of sitting together and exchange of opinions and happenings of the day which is traditionally called ‘Katchehry’ in Sindh.
Pervasivecomputingoffersenvironmentsinwhichuserneedsortasksarefulfilled without demanding their attention. This requires discovering a service or a set of services based on context (i.e. user presence, user activity, user location, temperature level,lightintensityleveletc.). Anatomicservicemaysometimesmeetthesimpleuser needs but meeting of complex user needs may lead to discovering a number of relevant services and composing them together. While the composed service may well serve userneeds,therecometimeswhenausermaywanttocustomizetheenvironmentbased on her preferences and this require adapting the composed service through parameter adjustment of one of its constituent services or a multiple constituent services. This makescontext-awarenessingeneralandcontextualservicecompositionandadaptation inparticularacorerequirementofpervasivecomputingapplications. Servicesavailable in the environment may be heterogeneous with regard to different discovery protocols (e.g., UPnP, SLP, JINI, etc.) being used fortheirpublication, discovery andinteraction. Context-aware service composition may involve discovery of heterogeneous services andtheadaptationofthecomposedservicemayinvolveinteractingwithheterogeneous constituent services. This raises the issue of service heterogeneity in context-aware service composition and adaptation. We have also proposed an approach following a separation of concerns, which allows adaptation decision logic (adaptation concern), a core part of context-aware applications, to be independently treated and managed as a separate unit of execution from the rest of application code. The proposed approach allows modelling of adaption concerns as declarative Event-Condition-Action (ECA) polices. This allows rapid development of context-aware applications and their dynamic modifiability. Another research issue that we address in this thesis is that of user involvement. Tothisend,wehaveproposedauser-centricapproachthatallowstheusertoparticipate in development of context-aware applications. To address aforementioned research challenges, we have designed and implemented a system whose detailed description is provided in the thesis. The system has been evaluated through usability,performance and scalability measures.
