Multimedia applications are becoming increasingly significant in modern world. The mushroom growth of multimedia data of these applications, particularly over the web has increased the demand for protection of copyright. Digital watermarking is much more acceptable as a solution to the problem of copyright protection and authentication of multimedia data while working in a networked environment. In this thesis a DWT based watermarking scheme is proposed. Wavelet transform is used because it has a number of advantages over other transforms, such as DCT. · It has multi-resolution hierarchical characteristics, and lower resolution embedding and detection which are computationally inexpensive. · The presentation of the image because of the hierarchical multi-resolution properties of the transformation is well-suited for applications where the multimedia data is transmitted regularly, as such in the application of video systems, or applications in real time. · Wavelet transform is closer to HVS contrast to DCT. For this reason, the range of artifacts introduced by wavelet is less infuriating as compared to DCT. For better imperceptibility, the watermarking technique should support a vision model which integrates various masking effects of the Human Visual System (HVS), to embed watermark in an invisible manner. For HVS we have used Watson’s Perceptual Model of JPEG2000. The basic aim of perceptual coding is, to conceal the watermark below the detection threshold. This can be obtained by making use of the HVS and JND threshold. The watermarking technique based on this model resists all types of common signal processing operations and many geometric attacks but unfortunately was not resistant against rotation. Keeping in mind this we explored Morton scanning. Morton scanning is used to

ذخیرہ اندوزی سے متعلق ہندومت، یہودیت اور اسلام کے احکام کا جائزہ

Hoarding is considered (Ihtikar) very abhorring and objectionable. It is the practice of keeping something in store and not bringing the same to the market so that prices may rise owing to this artificial dearth of supply in the market. Each religion of the world has agriculture rules. In these, rules about Hoarding play an important role. In non Semitic religions Hinduism is the largest religion of the world. Similarly in Semitic religions Islam is the second and Judaism is considered in third stage. All these three religions and there followers have good relation with agriculture. But among this, Islamic rules considers one of the best rules in the world. Because Hinduism agriculture rules affected by cast system and the other side Judaism rules is affected by customs and traditions. But still there are some points on which Hinduism, Judaism and Islam are completely supporting each others. Hoarding rules is one of them. This paper is consisting on hoarding rules in Hinduism, Judaism and Islam.

Feasibility of Inquiry-Based Teaching in a Lower Secondary Class Grade Vii of a Government School in Karachi

According to the national curriculum for Science (2006) major aim of teaching science is to develop scientific thinking in students, which can lead students to critical thinking, creativity and construction of practical based knowledge and they can relate science with their daily life experiences. In order to achieve this goal, there is dire need ofshifting classroom practices from teacher-centered to student-centered approach by adopting such teaching strategies where students can play dominant role. Inquiry-based teaching (IBT) is one of the teaching methods, which encourages construction of knowledge through students' participation. In this method students construct knowledge by identifying a problem, formulating question and hypotheses, collecting data and drawing conclusion through investigation. However, the practices of IBT do not exist in our science classroom. Therefore, this study is conducted to explore the feasibility of IBT in lower secondary section (Grade VII) of government school in Karachi (Pakistan). Keeping in view the nature of the study action research methodology based on Kemmis, Mc Taggart and Retallick (2004) cyclic model was employed. In total nine lessons were taught over a period of three weeks in the participant class. Data were collected through observation, interviews and informal discussion. There were two types of analysis one on going which was done along with data collection and overall which was done having completed the data collection phase. Inquiry was started from cookbook approach and the aim was to reach to independent inquiry. Finding of this study revealed that students started the journey of IBT from cook book, where they did the experiments according to the teacher's instructions. While at the end of nine lessons they reached somewhere between structured and guided inquiry where they did the investigation, made observation, collected the data and drew the conclusion. Findings of this study also showed a reasonable progression in terms of ability to respond and ask questions, conduct science experiment and collecting data. This study has highlighted group work, planning, piloting and use of no cost low cost material as promoting factors while, large classes, syllabus coverage and nature of exam as challenges in the implementation of IBT. The study has implications for science teachers as well as teacher educators in their teaching of science and professional training programmes respectively. It also generated many possibilities for further studies.
