This tutorial provides students with easy-to-use reference and overview of the materials required for circuits/electronics laboratories in an electrical engineering program. The tutorial is divided into three main separate sections: (1) general knowledge, (2) equipment operations, and (3) actual lab

The data were analysed quantitatively, by examining the most frequent responses to items on the questionnaire, and qualitatively, by looking closely at details illuminating the relationship between authors and publishers. The results, for present purposes, are divided into three broad bands of interest: first, what types of writing software authors are currently using; second, what the implications of using authors' disks in the publication chain are; and third, how technology alters perceptions of the 'copy' as a unit of sale. Findings suggest that though authors are operating at basic levels, they have embraced technology with more enthusiasm than their publishers. The challenge facing those involved in books is to make provision for presenting and displaying work in electronic form: to improve contracts and licensing agreements, and to disseminate information on technology to authors.

It provides medical support particularly to those who are living in remote areas and in emergency cases. Although developments in both technology and practice have been rapid, there are still many gaps in our knowledge with regard to the effective application of telehealth. This study investigated the classification of severity level in medical color images in telehealth, specifically the color red as one of the key symptoms when diagnosing different pathologies. The quality of medical images is safety critical when transmitting the symptoms of pathologies in telehealth, as distorted or degraded colors may result in errors. The study focused on the use of digital images in teleconsultation, particularly on images showing cellulitis (skin bacterial infection) as case study, as this pathology involve the color red in its diagnosis. Medical experts in dermatology were also involved to verify and select the relevant images u...

Taking the scale transformation into consideration, an extension of the iterative closest points (ICP) algorithm is introduced to solve the problem of registering a generic face model onto range scans with different sizes. A deformable model derived from thin shells is proposed to faithfully reconstruct face models and textures from range scans. Dense point correspondences are then established across different reconstructed face models so that facial expressions can be easily transferred from one face onto another by the deformation transfer technique. The proposed deformable model is also used to track the facial motion presented in 4D range scans and some preliminary results are obtained.

A review of the literature shows that experimental work can be improved and enhanced by taking onto account issues that characterise human-human communications. Results from three experiments are reported that exhibit the previously observed inconsistencies but this is arguably a function of task context. An alternative explanation is that the results are a reflection of the cognitive nature of tasks. Overall, the results point the way to further and future results in terms of refining procedures but also in terms of theoretical focus.

The main aims of the research have been to examine the effectiveness and user satisfaction of anthropomorphic feedback in various domains. The results are of use to all interactive systems designers, particularly when dealing with issues of user interface feedback design. There is currently some disagreement amongst computer scientists concerning the suitability of such types of feedback. This research is working to resolve this disagreement and in turn can help software houses to increase their profits by developing better user interfaces that will promote an increase in sales. The experiment detailed, concerns the specific software domain of Online Factual Delivery in the specific context of online hotel bookings. Anthropomorphic feedback was compared against an equivalent non-anthropomorphic feedback. Statistically significant results were obtained suggesting that the non-anthropomorphic feedback was more effective. The results for user satisfaction were however less clear.

The main aims of the research have been to examine the effectiveness and user satisfaction of anthropomorphic feedback in various domains. The results are of use to all interactive systems designers, particularly when dealing with issues of user interface feedback design. Currently the work in the area of anthropomorphic feedback does not have any global conclusions concerning its effectiveness and user satisfaction capabilities. This research is investigating finding a way for reaching some global conclusions concerning this type of feedback. The experiment detailed, concerns the specific software domain of software for in-depth learning in the specific context of PC building. Anthropomorphic feedback was compared against an equivalent non-anthropomorphic feedback. The results were not statistically significant to suggest one type of feedback was better than the other. It was also the aim to examine the types of feedback in relation to Cognitive Load Theory. The results suggest that the feedback types did not negatively affect Cognitive Load.

The main aims of the research have been to examine the effectiveness and user satisfaction of anthropomorphic feedback. The results are useful to all user interface designers wishing to improve the usability of their products. There is still disagreement in the research community concerning the usefulness of anthropomorphism at the user interface. This research is contributing knowledge to the aim of discovering whether such approaches are effective and liked by users. The experiment described in this paper, concerns the context of statistics tutoring/revision, which is part of the domain of software for in-depth learning. Anthropomorphic feedback was compared against an equivalent non-anthropomorphic feedback. The results indicated the anthropomorphic feedback to be preferred by users for some factors. However the evidence for effectiveness was inconclusive.

Some key issues involve determining whether such a medium is effective and liked by users. Discovering conclusive evidence in relation to this medium would help user interface designers produce better user interfaces. Currently conclusive evidence is lacking. However the authors of this paper have been investigating these issues for some time and this paper presents the results of an experiment which tested anthropomorphic voices against neutral voices. This was in the context of telephone bidding. The results indicated the impersonal human voice condition to foster higher bids, while the user satisfaction was inconclusive across all four conditions tested. The results have also been examined in terms of the Theory of Affordances with the aim of finding an explanation for the observed results. The results indicate that issues of affordances played a part in the results observed.
