Applying semantic web technologies to knowledge sharing in aerospace engineering
This paper details an integrated methodology to optimise Knowledge reuse and sharing, illustrated with a use case in the aeronautics domain. It uses Ontologies as a central modelling strategy for the Capture of Knowledge from legacy docu-ments via automated means, or directly in systems interfacing with Knowledge workers, via user-defined, web-based forms. The domain ontologies used for Knowledge Capture also guide the retrieval of the Knowledge extracted from the data using a Semantic Search System that provides support for multiple modalities during search. This approach has been applied and evaluated successfully within the aerospace domain, and is currently being extended for use in other domains on an increasingly large scale
An investigation to examine the most appropriate methodology to capture historical and modern preserved anatomical specimens for use in the digital age to improve access: a pilot study
Anatomico-pathological specimens constitute a valuable component of many medical museums or
institutional collections but can be limited in their impact on account of both physical and intellectual
inaccessibility. Further concerns relate to conservation as anatomical specimens may be subject to
tissue deterioration, constraints imposed by spatial or financial limitations of the host institution, or
accident-based destruction. In awareness of these issues, a simple and easily implementable
methodology to increase accessibility, impact and conservation of anatomical specimens is proposed
which combines photogrammetry, object virtual reality (object VR), and interactive portable document
format (PDF) with supplementary historical and anatomical commentary. The methodology was
developed using wet, dry, and plastinated specimens from the historical and modern collections in the
Museum of Anatomy at the University of Glasgow. It was found that photogrammetry yielded excellent
results for plastinated specimens and showed potential for dry specimens, while object VR produced
excellent photorealistic virtual specimens for all materials visualised. Use of PDF as output format was
found to allow for the addition of textual, visual, and interactive content, and as such supplemented the
virtual specimen with multidisciplinary information adaptable to the needs of various audiences. The
results of this small-scale pilot study indicate the beneficial nature of combining these established
techniques into a methodology for the digitisation and utilisation of historical anatomical collections in
particular, but also collections of material culture more broadly

Design issues in the production of hyperâbooks and visualâbooks
This paper describes an ongoing research project in the area of electronic books. After a brief overview of the state of the art in this field, two new forms of electronic book are presented: hyperâbooks and visualâbooks. A flexible environment allows them to be produced in a semiâautomatic way starting from different sources: electronic texts (as input for hyperâbooks) and paper books (as input for visualâbooks). The translation process is driven by the philosophy of preserving the book metaphor in order to guarantee that electronic information is presented in a familiar way. Another important feature of our research is that hyperâbooks and visualâbooks are conceived not as isolated objects but as entities within an electronic library, which inherits most of the features of a paperâbased library but introduces a number of new properties resulting from its nonâphysical nature
Reflectance Transformation Imaging (RTI) System for Ancient Documentary Artefacts
This tutorial summarises our uses of reflectance transformation imaging in archaeological contexts. It introduces the UK AHRC funded project reflectance Transformation Imaging for Anciant Documentary Artefacts and demonstrates imaging methodologies
Statistical model on student performance in UTHM by using non-parametric, semi-parametric and parametric survival analysis
Student performance defined as students who are capable to success during their studies. This study explored the use of survival analysis to investigate the performance of Bachelorâs degree students in Universiti Tun Hussein Onn Malaysia (UTHM). The data was collected from the Academic Management Office (AMO), UTHM. The main objective of this study is to estimate the survival rates of students with different entrance qualifications. The study also aim to identify the covariates that dominate the student performance, investigate the performance of Cox model based on the violation of the Proportional Hazard (PH) assumption, compare the model performance by using the survival and Accelerated Failure Time (AFT) models and estimate the time ratio (TR) of student performance in accordance to the selected best model. The survival analysis considered the survival approach such as the Kaplan-Meier (KM) method in the non-parametric method, Cox model in semi-parametric model and survival and AFT models in parametric model. The results revealed that students with STPM-entrance qualification had the highest survival rate compared to Diploma and Matriculation holders. The Cox model in the semi-parametric model identified the GPA, entrance qualification and course as the significant covariates to be included in the study. Faculty covariate was excluded since the p-value insignificant at 90% significance level. The result provided by the Cox model violated the PH assumptions. Then, the performance of the Cox model is less accurate. The invalidation performance of Cox model prompted the need to conduct other parametric survival and AFT models to produce more precise results. As a conclusion, the Log-normal AFT model is the best alternative model to estimate student performance in UTHM and other similar higher educational institution
Designing interoperable museum information systems
Museum collections are characterized by heterogeneity, since they usually host a plethora of objects of categories, while each of them requires different description policies and metadata standards. Moreover the museum records, which keep the history and evolution of the hosted collections, request proactive curation in order to preserve this rich and diverse information. In this paper,
the architecture of an innovative museum information system, as well as its implementation details is presented. In particular the requirements and the system architecture are presented along with the problems that were encountered. The main directions of the system design are (a) to increase interoperability levels and therefore assist proactive curation and (b) to enhance navigation by the usage of handheld devices. The first direction is satisfied by the design of a rich metadata schema based on the CIDOC/CRM standard. The second direction is fulfilled by the implementation of a module, which integrates the museum database with a subsystem appropriate to support user navigation into the museum floors and rooms. The module is expressed as a navigation functionality, which is accessed through handheld devices and peripherals, such as PDAs and RFID tags. The proposed system is functional and operates into the Solomos Museum, situated in Zakynthos island, Greece
