Development of Hypervideo Platform Using Object Databases
No full textWeb users are seizing on interactive capabilities that software suppliers have developed so far, and are eagerly awaiting new interactive capabilities now being demonstrated. This paper focuses the development of rich information environment based on a customized platform enabling hyperlinks on objects within a digital video. With the help of such environment, the viewer is able to view multiple videos concurrently and browse them temporally as well as spatially with the help of an object database. Specifically, the platform enables to traverse through that object by linking, and such links have been explored and created. The link may connect to within a video, or multiple running videos and/or World Wide Web object. The issues such as open hypermedia link base (static, generic or dynamic) and object database versus multiple videos are also investigated
Semantic Web Approach to Academic Program Assessment
No full textGenerally, the engineering program assessment process in line with an accreditation body involves some cyclic and tiring paperwork before any weakness is identified in the system. Additionally, the current state of such systems is that the assessment data are spread over many sub-systems, and there is no way to use them intelligently for better academic process management. It has been a desire of academic institutions to develop these processes in such a way that program management is also facilitated through an integrated system connecting all stakeholders of the program. This paper describes an electrical engineering program assessment process that has been developed and implemented using web semantics to provide intelligent services through an integrated system. The integrated system provides a value-added semantics layer where activities such as annotation, querying and reasoning can be carried out to support management. The framework is developed with a case study of a United Arab Emirates (UAE) University program assessment process to show how semantic web technologies can be used to facilitate program management

Object-database approach for a hypervideo platform
No full textWeb users are seizing on interactive capabilities that software suppliers have developed, and are eagerly awaiting new interactive capabilities now being demonstrated. The capabilities currently being explored include video browsing. This paper focuses on the development of a rich information environment based on a customized platform that enables hyperlinks on objects within a digital video. With the help of such an environment, the user is able to view multiple videos concurrently and browse them spatially and temporally, with the help of an object database. Specifically, the platform is expected to enable users to traverse through that object by linking, and such links have been explored. The links may connect to within a video, or multiple running videos and/or World Wide Web object. The issues such as open hypermedia link base and object database versus multiple videos are also investigated
Are Two Interviews Better Than One? Memory across Repeated Cognitive Interviews.
No full textEyewitnesses to a filmed event were interviewed twice using a Cognitive Interview to examine the effects of variations in delay between the repeated interviews (immediately & 2 days; immediately & 7 days; 7 & 9 days) and the identity of the interviewers (same or different across the two repeated interviews). Hypermnesia (an increase in total amount of information recalled in the repeated interview) occurred without any decrease in the overall accuracy. Reminiscence (the recall of new information in the repeated interview) was also found in all conditions but was least apparent in the longest delay condition, and came with little cost to the overall accuracy of information gathered. The number of errors, increased across the interviews, but the relative accuracy of participants' responses was unaffected. However, when accuracy was calculated based on all unique details provided across both interviews and compared to the accuracy of recall in just the first interview it was found to be slightly lower. The identity of the interviewer (whether the same or different across interviews) had no effects on the number of correct details. There was an increase in recall of new details with little cost to the overall accuracy of information gathered. Importantly, these results suggest that witnesses are unlikely to report everything they remember during a single Cognitive Interview, however exhaustive, and a second opportunity to recall information about the events in question may provide investigators with additional information
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Development of video based virtual studio
No full textThe objective of this research is multi-fold: to explore the approach for video production in virtual studio with a degree of freedom; to combine various existing technologies targeting each specific feature into one with almost all of the features needed for virtual studio; and above all to create high quality video production using graphics and video. The approach requires breaking down multiple videos up to frame level, so that multiple components/objects can be handled like graphics for further object level processing within three dimensions (3-D). We also provide a framework for describing different features of the stored media object. Initially a workbench is developed; where a user is allowed to open any type of standard graphic format (jpg, gif, bmp, avi or mpg) and can provide annotations. If the object is time based, then a time line is also provided. Real images are considered as a single frame, however the user can select the part of image to construct another media object. Finally, all required objects are mixed together to construct a final video. We compare this approach with existing ones in terms of the degree of freedom, platform independence and show that it can be used effectively in the domain of entertainment and education
Effect of iron limitation on the production of Streptolysin S (SLS) of <i>Streptococcus pyogenes</i> Group A
No full textThe effect of iron on the growth of <i>Streptococcus pyogenes</i> Group A and its influence on Streptolysisn S (SLS) production was investigated. Two strains of <i>S. pyogenes</i> used in this study C203S and 55903 M were grown in iron-restricted medium. The iron chelator, (Ethylenediamindi-(o- hydroxyphenyl-acetic acid) (EDDA) was added at a concentration giving a 10-fold molar excess over Fe. Successful growth of strains of <i>S. pyogenes</i> was obtained suggesting no absolute requirement for iron in the growth and the yield of SLS was not affected by the concentration of iron in the growth medium
