Nodal network generator for CAVE3
A new extension of CAVE3 code was developed that automates the creation of a finite difference math model in digital form ready for input to the CAVE3 code. The new software, Nodal Network Generator, is broken into two segments. One segment generates the model geometry using a Tektronix Tablet Digitizer and the other generates the actual finite difference model and allows for graphic verification using Tektronix 4014 Graphic Scope. Use of the Nodal Network Generator is described
Digital asset management system for small graphic design operations
According to the 1999 data of the U.S. Census Bureau, more than 75% of graphic design firms are small, with no more than four employees. Currently, there is a limited amount of literature relating to digital asset management (DAM) in relation to this population. These graphic design firms work on various projects using multiple digital assets for each, such as text, images, and fonts. Some firms choose to use proprietary asset management software to manage, search, and backup their assets, while others set up workflows that utilize existing network systems and graphic software.
This research is a case study which observes the current practices of asset management systems in small graphic design firms. First, asset management problems faced by participants were identified. Some of the basic challenges include naming conventions, folder nesting, and digital asset searchability. Most participants in this study want to make improvements in their file management practices.
Graphic design firms can improve their asset management system by keeping themselves informed of current DAM technologies; by relying less on personal memory and more on systematic organization; and by developing a checklist of important items to consider when managing digital assets, namely: naming convention, folder nesting, archiving, backup, searching, and means of asset transfer. In some cases, the solution is as simple as applying available desktop search engines to the workflow
Revisiting digital technologies: envisioning biodigital bodies
In this paper the contemporary practices of human genomics in the 21st century are placed alongside the digital bodies of the 1990s. The primary aim is to provide a trajectory of the biodigital as follows: First, digital bodies and biodigital bodies were both part of the spectacular imaginaries of early cybercultures. Second, these spectacular digital bodies were supplemented in the mid-1990s by digital bodywork practices that have become an important dimension of everyday communication. Third, the spectacle of biodigital bodies is in the process of being supplemented by biodigital bodywork practices, through personal or direct-to-consumer genomics. This shift moves a form of biodigital communication into the everyday. Finally, what can be learned from putting the trajectories of digital and biodigital bodies together is that the degree of this communicative shift may be obscured through the doubled attachment of personal genomics to everyday digital culture and high-tech spectacle.Keywords: genomics, biodigital, bodies, spectacle, everyda

Open-standards rich media mobile platform & rapid deployment service creation tool
This paper builds upon the work carried out by Brunel University in the field of "Fast Prototyping And Semi-automated User Interface And Application Generation for Converged Broadcast and Cellular Terminals" [1]. This work involved the development of a service creation application for interactive services on mobile devices and methodologies and tools to speed up and deskill the deployment process. This paper aims at further enhancing these tools and presents an enhanced open standards reference platform for mobile digital TV and rich media services. By using a Scalar Vector Graphics (SVG)-driven Java MIDP application (as opposed to bitmapped raster graphics-driven MHP), rich media services can be broadcast to mobile devices running various Java-supported platforms with a user interface scalable to any screen size. Moreover, the Rich Media Mobile Browser is integrated into a service creation tool, therefore enabling rapid testing and deployment of rich mobile media services.
The following sections detail the motivation behind the need for a platform which allows for rich media play-out on mobile devices, along with the rich media mobile viewing application and the tools used to create and test rich media with speed and ease
Techniques for augmenting the visualisation of dynamic raster surfaces
Despite their aesthetic appeal and condensed nature, dynamic raster surface representations such as a temporal series of a landform and an attribute series of a socio-economic attribute of an area, are often criticised for the lack of an effective information delivery and interactivity.In this work, we readdress some of the earlier raised reasons for these limitations -information-laden quality of surface datasets, lack of spatial and temporal continuity in the original data, and a limited scope for a real-time interactivity. We demonstrate with examples that the use of four techniques namely the re-expression of the surfaces as a framework of morphometric features, spatial generalisation, morphing, graphic lag and brushing can augment the visualisation of dynamic raster surfaces in temporal and attribute series
Semi-automated creation of converged iTV services: From macromedia director simulations to services ready for broadcast
While sound and video may capture viewers’ attention, interaction can captivate them. This has not been available prior to the advent of Digital Television. In fact, what lies at the heart of the Digital Television revolution
is this new type of interactive content, offered
in the form of interactive Television (iTV) services. On top of that, the new world of converged networks has created a demand for a new type of converged services on a range of mobile terminals (Tablet PCs, PDAs and mobile phones). This paper aims at presenting a new approach to service creation that allows for the semi-automatic translation of simulations and rapid prototypes created in the accessible desktop
multimedia authoring package Macromedia Director
into services ready for broadcast. This is achieved by a series of tools that de-skill and speed-up the process of creating digital TV user interfaces (UI) and applications for mobile terminals.
The benefits of rapid prototyping are essential for the production of these new types of services, and are therefore discussed in the first section of this paper.
In the following sections, an overview of the
operation of content, service, creation and management sub-systems is presented, which illustrates why these tools compose an important and integral part of a system responsible of creating, delivering and managing converged broadcast and telecommunications services.
The next section examines a number of metadata
languages candidates for describing the iTV services user interface and the schema language adopted in this project. A detailed description of the operation of the two tools is provided to offer an insight of how they can be used to de-skill and speed-up the process of creating digital TV user interfaces and applications for mobile terminals. Finally, representative broadcast oriented and telecommunication oriented converged service components are also introduced, demonstrating how these tools have been used to generate different types of services
Decision support system for planning telecommunication networks: a case study applied to the Andalusian region
Network planning is essential to design real Broadband Integrated Services Digital Networks (B-ISDN). This paper presents an OR application to the design of an optic fibre network for the andalusian region. The economical appraisal is the main consideration in order to take the appropriate decisions: hub location, region sizes and selection of the urban nodes that will receive telecommunication contents. A Decision Support System with a graphic interface that allows interactive analysis of different scenarios is presented. The system contains a set of mathematical programming models and it has the capability to dynamically construct and solve instances of those models. In addition, it provides data preparation and reports. The system is an integrated, user-friendly and powerful tool to make planning studies by firms developing cable network systems in the telecommunications market

Issues in multi-media information networks
In an integrated service environment, where users exchange various types of aural and visual information, networks should appear friendly to its users providing tools for management of multi-media information. Networks should also efficiently satisfy diverse performance requirements of different information being exchanged.In this paper we present new architecture for integrated service networks being investigated and developed by the Distributed Computation and Communication Group at the Department of Computer Science in the Columbia University. Research efforts are devoted to developing both (1) document management software to allow users to manipulate and relate text/graphics/voice information in a dynamic way, and (2) a tree network architecture for reliable and efficient exchange of multi-media information
Digital network analysis automation.
This thesis presents the development of a software package for the purpose of analyzing digital networks. The software package consists of two graphic user interfaces, one for the signal flow graph schematic drawing, and one for the analysis of digital network. Both are written in the WATFOR-77 programming language and by using the VGAWAT graphics library. The first graphic user interface software is to draw the signal flow graph of a 1-D, 2-D, or 3-D digital network using adders, delays, and multipliers. It can extract the graphical representation of a digital network with error checking capability into a netlist for analysis purpose. The netlist is formatted in the simplified matrix compute the frequency response, group delay and slope of magnitude response, first-order coefficient sensitivity, noise, and impulse response of a 1-D, 2-D, or 3-D digital network. Results are plotted in 2-D graphs for 1-D digital networks, and in 3-D graphs for 2-D and 3-D digital networks. Examples of 1-D, 2-D and 3-D digital network are given in this thesis.Dept. of Electrical and Computer Engineering.
