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.

کامل مُرشد دی پہچان

پھڑ دامن پیر منا لَے توں
اِنج سوکھا ای رب نوں پا لَے توں
رکھ پہلی پوڑی پیر میاں
انج کردا جا توں سیر میاں
تیری ہر دم ہووے خیر میاں
من اپنے نوں سمجھا لَے توں
پھڑ دامن پیر منا لَے توں
پھڑ مرشد کر انکار نہیں
بنِ مرشد بیڑا پار نہیں
لینی ہور کسے وی سار نہیں
اُس در تے ڈیرے لا لَے توں
پھڑ دامن پیر منا لَے توں
اوہ بستی یار مدینہ ہے
اوتھے ملدا نور خزینہ ہے
اوتھے ہوندا ٹھنڈا سینہ ہے
کر ہمت درشن پا لَے توں
پھڑ دامن پیر منا لَے توں

سوہنا مرشد ماڑی والا اے
جس کیتا نور اجالا اے
سدا وسن جھوکاں شالا اے
اُس در توں فیض کما لَے توں
پھڑ دامن پیر منا لَے توں

ایہو طرز طریقہ سارا جے
ایہو سب توں راز نیارا جے
اُس رب دا نام پیارا جے
اُس نام دا ورد پکا لَے توں
پھڑ دامن پیر منا لَے توں

ڈِٹھا خواجہ عبد رحمن میاں
ہِن دُھماں وچ جہان میاں
جتھے جھکدے شاہ سلطان میاں
اُس در توں فقر کما لَے توں
پھڑ دامن پیر منا لَے توں

اوہ مٹھا ہے خلق طبیعت دا
پابند اے بڑا شریعت دا
اوہ اچھا ہے ذہنیت دا
اوہدے در تے کلّی پا لَے توں
پھڑ دامن پیر منا لَے توں

اوہدا میتھوں سن توں حالا نی
اوہدا بہتا شان نرالا نی
اوہدا وارث کملی والا نی
اُس در تے جوگ کما لَے توں
پھڑ دامن پیر منا لَے توں

Linguistic Expressions of Prophet Muhammad (ﷺ) As a Miracle in Arabic Language: A Study of Linguistic Miracles of Prophet Muhammad

Arabian Peninsula was famous for its language expertise and linguistic expressions at the time of Prophet Muhammad (ﷺ). The poets and language experts would spend most of their lives to attain excellence in Arabic language and literature. It was during such time that a man named Muhammad (ﷺ) emerged, whose linguistic expression was remarkable, accurate and amazing. He was also quite familiar with the dialects and accents of every tribe of Arabia. It was the surprising effect of this linguistic excellence that people tagged him with different titles such as Poet, Sorcerer, Kāhin (soothsayer), Majnūn (One possessed by Jinn), and insane man with insane message. Allah Almighty revealed Qur’ānic verses not only to answer such allegations but also entrusted him to present commentary of the Holy Qur’ān to the people who would called him illiterate. This article will try to find out the Qur’ānic commentary on the linguistic expressions of Prophet Muhammad (ﷺ) as a miracle of revelation. The method of research is descriptive analytical and historical. The discussion of verses of Qur’ān and the explanations of the experts of Qur’ān through the comments of orientalists have been included to support the arguments. First Part of the paper discusses status of Prophet Muhammad (ﷺ) as an illiterate man with his remarkable linguistic expressions of Qur’ān due to which he was awarded different titles such as poet, sorcerer and insane. The second part explains the Qur’ānic response to accusations on Prophet (ﷺ) raised by the opponents. In the third part, some intellectual arguments of Qur’ān and opinions of orientalist have been discussed to support the Qur’ānic responses in favor of linguistic expressions of an “Ummi” Prophet Muhammad (ﷺ) which is followed by findings and conclusion of the whole discussion.

A Critical Study of the Problems of Educational Management in Private Sector Relating to Elementary Education in the Province of Sindh

Education, being the third eye, not only differentiates living being from dead, but also brings rapid growth and development. No nation can progress in globalization without education. Education has become an investment in this era. Private and public sectors are jointly making investment in education in most of the countries of the world to maximize the human source production. They face many problems in this process. The central theme of the research is to analyze the problems of educational management in private sector relating to elementary education in the province of Sindh. The sampling procedure adapted in this study was that of random cluster sampling procedure. A sample of 400 head teachers was randomly selected from 200 schools of Sindh. The data were collected through closed ended and open ended questionnaire, interview and observation tools. Chi-square was used to test the major hypothesis. It was found that head teachers had low academic and professional qualifications. Most elementary schools were established by the individuals for self employment or commercial purpose. The majority of privates schools were unregistered and working without any legal authority. The unregistered schools faced more problems than registered ones. The head teachers / owners had faced many problems in getting schools registered due to lengthy and complicated registration process, harsh attitude of registration officers and delays made by registration authorities. The students leaving private school used to face lot of problems due to diversity in syllabus of private and public school. Many schools were facing the problems of non-availability of textbooks. The head teachers used to hire the services of the staff at any time as per need, without advertising the posts and interviewing the candidates. While making appointments, the professional qualifications of candidates were not taken into consideration. The appointment was purely temporary with no job security to teaching and non-teaching staff. The head teachers did not Problems of educational management in private sector nominate / depute teachers for teacher training. The most of schools did not have their own building with sufficient number of classrooms and proper seating arrangement. Many schools were running in rented houses. The schools running in rental house faced more problems than schools running in their own building. The furniture and fixture was not adequate in most of the schools. The position of availability of basic facilities like play ground, boundary wall, assembly place, science lab, water room, lavatories and computer labs was not satisfactory. The schools did not have transport facilities. There was no arrangement of professional guidance and counseling. The schools did not have medical checkup arrangements. There was bottom up (decentralized) approach in most of schools. In most of the schools fee was the only source of finance of school and they often used to increase fee, recruit and terminate staff without seeking government permission. The schools did not receive any kind of encouragement and support from government functionaries to implement school development plans. There was no monitoring and evaluation mechanism to enhance the teacher effectiveness and performance. The rural area schools had more problems than urban area schools. Similarly the management problems were more in schools headed by owners than schools headed by experienced professionals. The owners did not have proper knowledge about planning, staffing, organizing, controlling, supervising and budgeting. Finally, suggestions are given at the end of paper.
