The DIADEM Software Development Methodology extended to Multimedia Interfaces

DIADEM, created by THOMSON-CSF, is a methodology for specifying and developing user interfaces. It improves productivity of the interface development process as well as quality of the interface. The method provides support to user interface development in three aspects. (1) DIADEM defines roles of people involved and their tasks and organises the sequence of activities. (2) It provides graphical formalisms supporting information exchange between people. (3) It offers a basic set of rules for optimum human-machine interfaces. The use of DIADEM in three areas (process control, sales support, and multimedia presentation) was observed and evaluated by our laboratory in the European project DIAMANTA (ESPRIT P20507). The method provides an open procedure that leaves room for adaptation to a specific application and environment. This paper gives an overview of DIADEM and shows how to extend formalisms for developing multimedia interfaces.

Evolution in software systems: foundations of the SPE classification scheme

The SPE taxonomy of evolving software systems, first proposed by Lehman in 1980, is re-examined in this work. The primary concepts of software evolution are related to generic theories of evolution, particularly Dawkins' concept of a replicator, to the hermeneutic tradition in philosophy and to Kuhn's concept of paradigm. These concepts provide the foundations that are needed for understanding the phenomenon of software evolution and for refining the definitions of the SPE categories. In particular, this work argues that a software system should be defined as of type P if its controlling stakeholders have made a strategic decision that the system must comply with a single paradigm in its representation of domain knowledge. The proposed refinement of SPE is expected to provide a more productive basis for developing testable hypotheses and models about possible differences in the evolution of E- and P-type systems than is provided by the original scheme.

Strategic organization in projects and firms through software integration

As integrated software solutions reshape project delivery, they alter the bases for collaboration and competition across firms in complex industries. This paper synthesises and extends literatures on strategy in project-based industries and digitally-integrated work to understand how project-based firms interact with digital infrastructures for project delivery. Four identified strategies are to: 1) develop and use capabilities to shape the integrated software solutions that are used in projects; 2) co-specialize, developing complementary assets to work repeatedly with a particular integrator firm; 3) retain flexibility by developing and maintaining capabilities in multiple digital technologies and processes; and 4) manage interfaces, translating work into project formats for coordination while hiding proprietary data and capabilities in internal systems. The paper articulates the strategic importance of digital infrastructures for delivery as well as product architectures. It concludes by discussing managerial implications of the identified strategies and areas for further research.

Generic unified modelling process for developing semantically rich, dynamic and temporal models

Models play a vital role in supporting a range of activities in numerous domains. We rely on models to support the design, visualisation, analysis and representation of parts of the world around us, and as such significant research effort has been invested into numerous areas of modelling; including support for model semantics, dynamic states and behaviour, temporal data storage and visualisation. Whilst these efforts have increased our capabilities and allowed us to create increasingly powerful software-based models, the process of developing models, supporting tools and /or data structures remains difficult, expensive and error-prone. In this paper we define from literature the key factors in assessing a model’s quality and usefulness: semantic richness, support for dynamic states and object behaviour, temporal data storage and visualisation. We also identify a number of shortcomings in both existing modelling standards and model development processes and propose a unified generic process to guide users through the development of semantically rich, dynamic and temporal models.

Developing a mobile visualization environment for construction applications

There is a renewed interest in immersive visualization to navigate digital data-sets associated with large building and infrastructure projects. Following work with a fully immersive visualization facility at the University, this paper details the development of a complementary mobile visualization environment. It articulates progress on the requirements for this facility; the overall design of hardware and software; and the laboratory testing and planning for user pilots in construction applications. Like our fixed facility, this new light-weight mobile solution enables a group of users to navigate a 3D model at a 1:1 scale and to work collaboratively with structured asset information. However it offers greater flexibility as two users can assemble and start using it at a new location within an hour. The solution has been developed and tested in a laboratory and will be piloted in engineering design review and stakeholder engagement applications on a major construction project.

Developing a Communication link between Agents and cross Platform IDE

The main objective of this thesis work is to develop communication link between Runrev Revolution (IDE) and JADE (Multi-Agent System) through Socket programming using TCP/IP layer. These two independent platforms are connected using socket programming technique. Socket programming is considered to be newly emerging technology among these two platforms, the work done in this thesis work is considered to be a prototype.A Graphical simulation model is developed by salixphere (Company in Hedemora) to simulate logistic problems using Runrev Revolution (IDE). The simulation software/program is called “BIOSIM”. The logistic problems are complex, and conventional optimization techniques are unlikely very successful. “BIOSIM” can demonstrate the graphical representation of logistic problems depending upon the problem domains. As this simulation model is developed in revolution programming language (Transcript) which is dynamically typed and English-like language, it is quite slow compared to other high level programming languages. The object of this thesis work is to add intelligent behaviour in graphical objects and develop communication link between Runrev revolution (IDE) and JADE (Multi-Agent System) using TCP/IP layers.The test shows the intelligent behaviour in the graphical objects and successful communication between Runrev Revolution (IDE) and JADE (Multi-Agent System).

Engaging with stakeholders or constructing them? Attitudes and assumptions in stakeholder software

New activists are engaging in a range of extra-parliamentary activities, including extensive use of the internet, to create political change at local, national and international levels. As new activists become more effective, more sophisticated and, above all, more organised, traditional public relations or ‘PR spin’ is increasingly exposed as not just ineffective, but also an unethical way to respond to criticisms. But growing numbers of state and business organisations are trying to create new relationships with stakeholders that are inclusive, sustainable and aligned with the principles of corporate social responsibility (CSR). A range of stakeholder communication software packages claim to guide and support organisations wishing to create such relationships. However, these software packages can do more than merely offer guidance and support. They can actively influence how an organisation engages with stakeholders by embodying particular discourses that construct stakeholders as adversaries. This article examines two stakeholder software packages, showing how each one’s rhetoric of inclusion accompanies discourses that recreate adversarial relationships between organisation and stakeholders. The article sets such developments against the broad backdrop of developing notions of CSR, arguing that the uncritical use of stakeholder communication packages can reduce CSR to ‘more PR spin’.

PrIMe: A Methodology for Developing Provenance-Aware Applications

Provenance refers to the past processes that brought about a given (version of an) object, item or entity. By knowing the provenance of data, users can often better understand, trust, reproduce, and validate it. A provenance-aware application has the functionality to answer questions regarding the provenance of the data it produces, by using documentation of past processes. PrIMe is a software engineering technique for adapting application designs to enable them to interact with a provenance middleware layer, thereby making them provenance-aware. In this article, we specify the steps involved in applying PrIMe, analyse its effectiveness, and illustrate its use with two case studies, in bioinformatics and medicine.

Technologies and considerations for developing internet and multiplayer computer games: a tutorial (extended abstract)

Games are universal and probably as old as humankind. Today the development of computer technology, especially the development of fast networks and the Internet, brings games a faster growth than ever before. Game design and development is now a fast-growing entertainment field, with a lot to offer professionally and creatively. In fact, from IT professional’s point of view, creating computer games provides us with all the usual technical challenges associated with software development, such as requirement analysis, architectural design, rapid prototyping, HCI, parallel and distributed processing, code reuse, programming, performance evaluation, testing and maintenance. It also provides challenges on other exciting aspects, such as storyboarding, screenplays, illustration, animation, sound effects, music, and social impact. By developing a computer game from start to finish, one would be able to acquire multi-disciplinary knowledge to become an IT professional for the modern era.

Productive on-line student support : developing a system for primary mathematics trainee teachers

This paper outlines the development project for the 'Productive on-line student support system', a student "self-help" system, at Deakin University. The aim of this project was to provide Deakin primary teacher education students with a web-based learning tool that allowed them to assess and diagnose their strengths and weaknesses in mathematics, and supports students in their mathematics learning, and in so doing produce mathematically competent graduates. This project was, like similar programs, a development of peer or cross-age tutoring common in primary and secondary schools. A grant under the Deakin University Strategic Teaching and Learning Grant Scheme enabled a staff team from the mathematics education group, to develop a sophisticated and well-designed system that catered for a wide range of student needs, provided useful feedback, and was engaging and easy to use. The under-pinning software for the system was WebCT, available to staff through the Deakin Studies On-line system, to which students are connected also. The 'Productive on-line student support system' enabled students to determine their own mathematical needs, and have these addressed whenever they wished, as often as they wished, and allowed self-monitoring of progress. An outline of the system and examples of the assessment materials will be presented.

Developing a facility for glass façade performance testing

This research aims to investigate whether real spaces can support legitimate measurements on glazing energy and thermal comfort analysis. This paper presents the development of a research facility for doing this. It will test simple to complex glazing and shading systems in a real (occupied) interior office environment. The purpose of this research project is to compare measured results with those being simulated with existing software and to discover discrepancies between simulation and real measured results. What parameters characterize a glazing system, whether simple or complex? Can these parameters be used to predict the energy transfer and comfort in the space? One must begin with simple glazing systems and verify measured with readily known simulated results. It is, at present, very difficult to use geometric based software with thermal based software to predict the performance of complex glazing systems. However, if we can characterize glazing systems with a set of reliable measurements, we can provide the data necessary for predicting performance in a live space. Specifically, the Solar Heat Gain Coefficient (SHGC) is a variable parameter based upon solar incident angle to a glazing system and is intended to be measured in its integral components: solar transmittance and inward-flowing fraction (radiative/convective) heat gain. A new instrumental approach through variable surface coated heat flux meters is being investigated to provide the measurement of interior glazing surface radiative and convective heat gain. The results suggest that this instrumentation may support be a viable method of testing inward-flowing heat gains from the interior glass surface. The test set-up also considers the application of a well-known B&K 1221 Comfort Meter for determining thermal comfort responses in the ‘perimeter zone’ on the interior side of a façade. This work requires further investigation, but is intended to be used in conjunction with solar pyranometers measuring transmittance as well as the heat flux meter and surface temperature instrumentation.

A survey of Australian human services agency software usage

Human Services agencies use a wide range of software systems to manage caseloads, maintain records, deliver services to clients, and for interagency communication. Some systems are generic, such as Word or Excel, while some are specialized to the organization, such as specialized databases for tracking case notes. Some software systems are shared across organizations. We surveyed nearly 40 Australian Human Services agencies to ascertain the range of software currently in use by agencies and their opinions on it, with a view to identifying promising new Human Services applications. We interviewed representatives from a selection of smaller agencies. This resulted in detailed feedback on key issues to consider when developing and deploying new Human Services software.

Software Tools For Large Scale Interactive Hydrodynamic Modeling

Running hydrodynamic models interactively allows both visual exploration and change of model state during simulation. One of the main characteristics of an interactive model is that it should provide immediate feedback to the user, for example respond to changes in model state or view settings. For this reason, such features are usually only available for models with a relatively small number of computational cells, which are used mainly for demonstration and educational purposes. It would be useful if interactive modeling would also work for models typically used in consultancy projects involving large scale simulations. This results in a number of technical challenges related to the combination of the model itself and the visualisation tools (scalability, implementation of an appropriate API for control and access to the internal state). While model parallelisation is increasingly addressed by the environmental modeling community, little effort has been spent on developing a high-performance interactive environment. What can we learn from other high-end visualisation domains such as 3D animation, gaming, virtual globes (Autodesk 3ds Max, Second Life, Google Earth) that also focus on efficient interaction with 3D environments? In these domains high efficiency is usually achieved by the use of computer graphics algorithms such as surface simplification depending on current view, distance to objects, and efficient caching of the aggregated representation of object meshes. We investigate how these algorithms can be re-used in the context of interactive hydrodynamic modeling without significant changes to the model code and allowing model operation on both multi-core CPU personal computers and high-performance computer clusters.

Desenvolvimento de sistemas de informação com base em objetos de negócios : um protocolo de análise com vistas à reutilização de software

O objetivo da pesquisa atém-se primeiramente em elaborar um protocolo que permita analisar, por meio de um conjunto de indicadores, o processo de reutilização de software no desenvolvimento de sistemas de informação modelando objetos de negócios. O protocolo concebido compõe-se de um modelo analítico e de grades de análise, a serem empregadas na classificação e tabulação dos dados obtidos empiricamente. Com vistas à validação inicial do protocolo de análise, realiza-se um estudo de caso. A investigação ocorre num dos primeiros e, no momento, maior projeto de fornecimento de elementos de software reutilizáveis destinados a negócios, o IBM SANFRANCISCO, bem como no primeiro projeto desenvolvido no Brasil com base no por ele disponibilizado, o sistema Apontamento Universal de Horas (TIME SHEET System). Quanto à aplicabilidade do protocolo na prática, este se mostra abrangente e adequado à compreensão do processo. Quanto aos resultados do estudo de caso, a análise dos dados revela uma situação em que as expectativas (dos pesquisadores) de reutilização de elementos de software orientadas a negócio eram superiores ao observado. Houve, entretanto, reutilização de elementos de baixo nível, que forneceram a infra-estrutura necessária para o desenvolvimento do projeto. Os resultados contextualizados diante das expectativas de reutilização (dos desenvolvedores) são positivos, na medida em que houve benefícios metodológicos e tecnológicos decorrentes da parceria realizada. Por outro lado, constatam-se alguns aspectos restritivos para o desenvolvedor de aplicativos, em virtude de escolhas arbitrárias realizadas pelo provedor de elementos reutilizáveis.

A trajetória do ambiente jurídico-institucional do setor de software no Brasil e na Índia: identidades, diferenças e repercussões

Há mais de 30 anos o Brasil tem desenvolvido políticas específicas para o setor de informática, desde a Política Nacional de Informática da década de 70, passando pelo Período de Reserva de Mercado dos anos 80 e, nos dias de hoje, em que as Tecnologias de Informação e Comunicação (TIC) são tidas como uma das áreas prioritárias na Política Industrial. Dentre as metas atuais, destaca-se o foco na ampliação do volume de exportações de software e serviços. Contudo, apesar dessas pretensões, o país não tem tido destaque internacional expressivo para o setor. Por outro lado, a Índia, também considerada como um país emergente, figurando na lista dos BRIC, foi responsável pela exportação de cerca de US$47 bilhões em software e serviços de Tecnologia da Informação (TI) em 2009, se destacando como um país protagonista no mercado internacional do setor. A implementação de uma indústria tecnicamente sofisticada como a do software, que exige um ambiente propício à inovação, em um país em desenvolvimento como a Índia chama a atenção. De certo existiram arranjos jurídico-institucionais que foram utilizados naquele país. Quais? Em que medida tais arranjos ajudaram no desenvolvimento indiano do setor? E no Brasil? Este trabalho parte da hipótese de que o ambiente jurídico-institucional desses países definiu fluxos de conhecimento distintos, influenciando o tipo de desenvolvimento do setor de software de cada um. Averiguar como, entre outros fatores sócio-econômicos, esses arranjos jurídico-institucionais influenciaram na conformação diversa de fluxos de conhecimento é o objetivo específico desta pesquisa. Entende-se aqui como ambiente jurídico-institucional todas as regulamentações que estabelecem instituições, diretrizes e condições comuns para determinado tema. Partindo do pressuposto de que o setor de software desenvolve atividades intensivas em conhecimento, para cada país em questão, serão analisados apenas arranjos jurídico-institucionais que tiveram, ou têm, poder de delimitar o fluxo de conhecimento referente ao setor, sejam eles provenientes de políticas comerciais (de exportação e importação, ou de propriedade intelectual) ou de políticas de investimento para inovação. A questão fundamental ultrapassa o debate se o Estado deve ou não intervir, para focar-se na análise sobre os diferentes tipos de envolvimento observados e quais os seus efeitos. Para tal, além de revisão bibliográfica, foi feita uma pesquisa de campo na Índia (Delhi, Mumbai, Bangalore) e no Brasil (São Paulo, Brasília e Rio de Janeiro), onde foram conduzidas entrevistas com empresas e associações de software, gestores públicos e acadêmicos que estudam o setor.
