Perfusion technology is a mechanical and visual science traditionally taught with didactic instruction combined with clinical experience. It is difficult to provide perfusion students the opportunity to experience difficult clinical situations, set up complex perfusion equipment, or observe corrective measures taken during catastrophic events because of patient safety concerns. Although high fi...

The video quality assessment must be adapted to the human visual system, which is why researchers have performed subjective viewing experiments in order to obtain the conditions of encoding of video systems to provide the best quality to the user. The objective of this study is to assess the video quality using image features extraction without using reference video. RMSE values and processing ...

PURPOSE The demand for long term EEG monitoring is increasing with the emphasis on recording patients' attacks. Outpatient ambulatory EEG is relatively inexpensive and widely available. The main disadvantage of the technique is the lack of video which can make interpretation of an ictus difficult. We investigated whether patients, if offered home video equipment, would take it, if this resulted...

this study involved 154 anesthetized patients requiring endotracheal intubation, in whom the epiglottis was visible but not lifted, which restricted the view of the glottis. a simple stylet was used to lift the epiglottis, thus improving the view of the glottis with the glide scope®, allowing tracheal tubes to be inserted into the patients. the stylet easily resolved the difficulty of lifting t...

A priority issue within coal mines is ensuring the safety of underground personnel. It is vitally important to have upto-date information about: which districts personnel are working; if there is adequate provision of safety equipment and facilities, and whether the mine enviroment is hazardous. This paper canvasses recent developments in proximity identification and tracking techologies for mi...

This paper presents modelling and analysis of a mobile 3DTV broadcast system for handheld devices. The underlying technology behind our system is the DVB-H specification which brings ordinary TV broadcast services to batterypowered handheld receivers. In our system, we simulated the broadcast of stereo video content over DVB-H to mobile handheld devices with autostereoscopic displays. In this w...

4 This guide is written for occupational hygienists, ventilation engineers, health and safety practitioners and others interested in how exposures to airborne particles occur. It briefly explains the principles of the dust lamp, its use in observing the presence of airborne particles, and identifies its advantages and limitations. Appendices covering lighting terminology, lighting equipment, te...

Telemedicine offers the potential to alleviate the severe shortage of medical specialists in developing countries. However lack of equipment and poor network connections usually rule out video-conferencing systems. This paper describes a software application to facilitate store-and-forward telemedicine by email of images from digital cameras. TeleMedMail is written in Java and allows structured...
