Using object and trajectory analysis to facilitate indexing and retrieval of video

This paper aims to show that by using low level feature extraction, motion and object identifying and tracking methods, features can be extracted and indexed for efficient and effective retrieval for video; such as an awards ceremony video. Video scene/shot analysis and key frame extraction are used as a foundation to identify objects in video and be able to find spatial relationships within the video. The compounding of low level features such as colour, texture and abstract object identification lead into higher level real object identification and tracking and scene detection. The main focus is on using a video style that is different to the heavily used sports and news genres. Using different video styles can open the door to creating methods that could encompass all video types instead of specialized methods for each specific style of video.

The meta-object facility typed

The Object Managment Group’s Meta-Object Facility (MOF) is a semiformal approach to writing models and metamodels (models of models). The MOF was developed to enable systematic model/metamodel interchange and integration. The approach is problematic, unless metamodels are correctly specified: an error in a metamodel specification will propagate throughout instantiating models and final model implementations. An important open question is how to develop provably correct metamodels. This paper outlines a solution to the question, in which the MOF metamodelling approach is formalized within constructive type theory.

Democratising the literary experience: metafiction in the novels of Agusta Wibisono

This paper is a study of the intersection of text, context and presentation in Agusta Wibisono's two novels based on the wayang shadow puppet theatre of Central Java, Balada Narasoma (The Ballad of Narasoma) (1990) and Balada Cinta Abimanyu dan Lady Sundari (The Ballad of the Love of Abimanyu and Lady Sundari) (1990). It should be observed from the outset that in the field of modern Indonesian literary studies Agusta Wibisono is a virtually unknown figure, and in Indonesia his two novels are long out of print and now extremely hard to find. The publishing house responsible for the novels' initial print run, Pustakakarya Grafikatama, is now defunct. Adding to the enigma surrounding this man, Agusta Wibisono is in fact a pseudonym for a writer and a pilot in the Indonesian airforce, Mohammad Agus Suhadi.

Object oriented finite element analysis: a distributed approach to mesh generation

The object-oriented finite element method (OOFEM) has attracted the attention of many researchers. Compared with the traditional finite element method, OOFEM software has the advantages of maintenance and reuse. Moreover, it is easier to expand the architecture to a distributed one. In this paper, we introduce a distributed architecture of a object-oriented finite element preprocessor. A comparison between the distributed system and the centralised system shows that the former, presented in the paper, greatly improves the performance of mesh generation. Other finite element analysis modules could be expanded according to this architecture.

The design and development of an integrated system for object-oriented finite element computing

Finite Element Method (FEM) is widely used in Science and Engineering since 1960’s. The vast majority of FEM software is procedure-oriented. However, this conventional style of designing FEM software encounters problems in maintenance, reuse, and expansion of the software. Recently the object-oriented finite element method attracts the attention of lots of researchers, and now there is a growing interest in this method. In this paper, the object-oriented finite element (OOFE) is briefly introduced. Then the design and development of an integrated OOFE system is described. A comparison of the integrated OOFE system and a procedure-oriented system shows that our OOFE system has many advantages.

Web publishing revisited-a case study of literary websites in Russia

The concept of web publishing has been widely discussed in IS research literature since the WWW emerged. The discussion in various publications often revolves around the issues of business success and profitability, web design, and effective content presentation. This paper is a study of one of the “unknown” segments of the Internet - a family of websites publishing literary works in the Russian language. We demonstrate that the innovative model adopted by site owners in building the relationships with the site customers, and the information technology selected for the sites can play a crucial role in the success of a web-based venture. Our analysis is based on the concepts of virtual community and socio-technical interaction. We discuss the  contribution of this case not only to the innovative use of the Web-based business models, but also to the new forms of literary life and national  culture. Some of the concepts, principles and practices, adopted on those sites may be of interest to the Internet developers and communities worldwide.

Object-oriented security modelling for healthcare

With the convergence of paper to electronic, the health industry is relying more on technology to maintain and update the well-being of patients. This reliance on technology requires an acute level of protection from unwanted technological disasters and/or human threats. Research shows insufficiencies with the implementation and use of security controls; as well as current analysis methods lacking the techniques to analyse technical and social aspects of security. The aim of this paper is to introduce an information security evaluation methodology for health information systems based on UML.

Virtual non-profit organisations : literary virtual communities in Russia

This paper is a study of one of the "unknown" segments of the Internet - non-profit ventures in the Russian language. Based on the understanding of the concept of virtual community we consider the family of free publishing literary websites. We discuss their experience to demonstrate their contribution not only to the national culture, but also to the creation of open and democratic society in the former communist world, and to new forms of literary life. Some of the innovative concepts, principles and practices, adopted on those sites may be of interest to the Internet developers and communities worldwide.

Computational simulation of gas flow and heat transfer near an immersed object in fluidized beds

To improve the understanding of the heat transfer mechanism and to find a reliable and simple heat-transfer model, the gas flow and heat transfer between fluidized beds and the surfaces of an immersed object is numerically simulated based on a double particle-layer and porous medium model. The velocity field and temperature distribution of the gas and particles are analysed during the heat transfer process. The simulation shows that the change of gas velocity with the distance from immersed surface is consistent with the variation of bed voidage, and is used to validate approximately dimensional analysing result that the gas velocity between immersed surface and particles is 4.6Umf/εmf. The effects of particle size and particle residence time on the thermal penetration depth and the heat-transfer coefficients are also discussed.

Simultaneous estimation of optical flow and object state: A modified approach to optical flow calculation

Differential optical flow methods are widely used within the computer vision community. They are classified as being either local, as in the Lucas-Kanade method, or global, as in the Horn-Schunck technique. As the physical dynamics of an object is inherently coupled into the behavior of its image in the video stream, in this paper, we use such dynamic parameter information in calculating optical flow when tracking a moving object using a video stream. Indeed, we use a modified error function in the minimization that contains physical parameter information. Further, the refined estimates of optical flow is used for better estimation of the physical parameters of the object in the simultaneous estimation of optical flow and object state(SEOS).

Stereo-vision-based moving object tracking via robust linear filtering

Vision-based tracking sensors typically provide nonlinear measurements
of the targets Cartesian position and velocity state components. In this paper we derive linear measurements using an analytical measurement conversion technique which can be used with two (or more) vision sensors. We derive
linear measurements in the target’s Cartesian position and velocity components and we derive a robust version of a linear Kalman filter. We show that our linear robust filter significantly outperforms the extended Kalman Filter. Moreover, we prove that the state estimation error is bounded.
