شوقِ دیدارِ یار مت پوچھو

شوقِ دیدارِ یار مت پوچھو
دل ہے کیا بے قرار مت پوچھو

دل، جگر، جان، کچھ بچا ہی نہیں
اس کی نظروں کے وار مت پوچھو

جتنے کورے ہیں عشق دریا میں
کس طرح ہوں گے پار مت پوچھو

اس کی آنکھوں کی سحر کاری کا
قیس! دیوانہ وار مت پوچھو

میرے سینے میں تم دھڑکتے ہو
تجھ سے کتنا ہے پیار مت پوچھو

جسم سونے کا سر بہ سر ہے فضاؔ
کیا ہے روہی کی نار، مت پوچھو

Pak-China Defense Cooperation and Evolving International Relations

This study is about the impact of different global and regional changes resulting from PakistanChina’s defense cooperation and further examines the increasing range of diplomatic cooperation in the social, tactical, and economic realms. The paper focuses on three events: (i) the 1978 transformation of China and its opening-up policies; (ii) disbanding of the U.S.S.R (1991); and (iii) the event of 9/11 in the United States. These events had a significant influence on Pak-China ties. This study is a literature review and contributes to a better understanding of the evolving international systems namely the India-U.S. Tactical relations and strategic cooperation. The paper concludes that China and Pakistan need to preserve amicable, strategic, and diplomatic connections with one another as it is necessary for the peace, security, and economic development of not only China and Pakistan but for the region overall.

Ontology Based Semantic Concurrent Activity Recognition

Activity recognition has a vital role in smart home operations. Major challenges in activity recognition are personalization, recognising parallel and interleave activities, erratic degree of dissimilar activities, identification of same object used in multiple activities, catering sensor noise caused by mal-interactions, dynamically determining the context of personalized activities and evolution of generic activity model for new activities. Moreover, object-sensor-based activity recognition by learning for complete activity pattern derived from a generic activity model in sequential and parallel activities may also be asserted as open research realms. A dynamic and generic framework named Ontology driven Semantic Activity Recognition (OSCAR) has been proposed to address the asserted challenges through hybrid of data driven techniques, temporal formalism and knowledge-driven techniques. An unlabelled sensor stream generated by inhabitant’s interactions has been accumulated into sensor repositories that is processed by OSCAR to recognise personalized activities performed in sequential or interleaved fashion. The major modules of OSCAR for activity recognition are sensor properties sequencer, semantic segmentor, personalized activity learner, spurious filter model and ontology evolution model. The spurious semantic segmentation produced by sensor noise or erratic behaviour is removed by Allen’s temporal formalism. Moreover, Tversky’s feature-based similarity has been used to remove the highly similar spurious activities produced as a result of mistaken interactions with wrong home objects. A comprehensive set of experiments has been carried out for evaluating the effectiveness of OSCAR over different metrics such as chi-square distribution, precision, recall and f-measure. In order to measure the performance of proposed technique covering all the possible actions/activities. A standard dataset, named CASAS, has been used for making a comparative analysis of different scenarios in activity recognition with state of the art work by Riboni and KCAR. In order to validate distinct research perspectives such as sensor noise, learning user specific actions; no dataset could comprehend these scenarios to the best of our knowledge. So, a dataset named Data Acquisition Methodology for Smart Homes (DAMSH) was developed while adhering to standard guidelines. The evaluation using stated metrics, over different datasets and comparative analysis with prevalent techniques assert OSCAR as a viable and superior solution. The efficacy of OSCAR is complemented by the distinctive features of dynamically learning personalized actions of inhabitants, boundary detection of activities, ontologies, identification and elimination spurious actions and seed knowledge evolution through ontologies.
