Recently, various kinds of high-quality media systems have been developed. It is expected that these systems can be used to remote lectures. We are adopting these systems including high-speed network to construct a remote lecture based on "Instruction with Blackboard", which provides old-fashioned but very common style of lecture. This instruction style has been often avoided in remote lecture ...

We are developing a cross-media information retrieval system, in which users can view specific segments of lecture videos by submitting text queries. To produce a text index, the audio track is extracted from a lecture video and a transcription is generated by automatic speech recognition. In this paper, to improve the quality of our retrieval system, we extensively investigate the effects of a...

This paper presents an automated system for authoring of hypermedia lecture recordings. We revised our previous work on lectures indexation. Our original method of lectures indexation needed a human interaction and was not feasible for large amount of lectures. We developed a system which utilizes Optical Character Recognition (OCR) to automatically extract the keywords from the lecture slides ...

Overview These notes consists of ve lectures. Each lecture covers the material that I will present with fuller details and exercises. I have also included some material in appendices which the reader might nd interesting but which I will not have time to cover in my lectures. Lecture 1 introduces both linear Grr obner bases and Grr obner bases for algebras. Lecture 2 surveys some of the basis a...

introduction: bedsideteaching is defined as teaching in the presence of a patient, it is a vital component of medical education. the aim of this study was to evaluate the effectiveness of two methods of case based teaching (at the bedside and in the classroom) in the teaching hospitals (for both undergraduates and residents of pediatrics). methods: thirty undergraduates and twenty pediatric res...

An interesting concept associated with linear programs is that of duality. For every LP problem there is a second LP problem with which it is intrinsically paired. This second LP problem can bound the feasible values of the first problem and even help find the optimal value to that problem. The initial LP problem is called the primal LP while the second is referred to as the dual LP. Consider t...

conclusions lecture and educational package can both improve some dimensions of the qol in patients with hypertension. however, as pamphlets are cheap and easy to use, this method may be used as an effective method for self-care education in health care settings in iran, where the system is faced with nursing shortage. results no significant differences were observed between the three groups fo...
