خُود کو دیکھ رہا ہوں کیا ہے
وہ کیوں مجھ کو چھُوڑ گیا ہے
پھر دل غم سے نڈھال ہوا ہے
ہجر تعلق ، ٹوٹ چکا ہے
یاروں سے کیا شِکوہ کرنا
بس یوں ہی دل بھر آیا ہے
اِس دل کی نگری کا راجا
پتھّر ہے یا پتھّر کا ہے
اَب بُلبُل کو شب ہو جائے
کب کوئی جُگنو آتا ہے
کلی جو کھل کر پھول بنی تھی
پھول کسی نے توڑ لیا ہے
سارے پتّے زرد ہوئے ہیں
پیڑ کو کیا غم ہو سکتا ہے!
لوگ پوچھتے ہیں کیا غم ہے
رنگ ترا بھی ناصرؔ سا ہے
ساری دنیا پاس ہے صادقؔ
تو پھر بھی کتنا تنہا ہے
In Islam the system of Judiciary halds an immense importance the judiciary after faith is counted as an important obligation amongst all other obligations and is eminent and virtous amongst all outs of worships. The virue of judiciary is mentioned at hundreds of places in the Quran and in the Ahadiths. The Progression of the system of judiciary has been hard from the begning of the prophet hood, during the Rashidun ealiphale and is promulgated till tody. Before the existence of Pakistan there were many states amongst which one was the state of Kalat. Where the Baloch Government was setup in 1530 Meer Ahmed Yar Khan was elected as the Khan of Kalat. Who at the very Beginning laid the foundation of the system of judiciary? The details about this would be discussed in the article ahead. The Government of Balochs was set up in Kalat the foundation of system of judiciary here was first of all laid by Mir Ahmed Yar Khan. First of all juges were appointed in every district.
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.
