The EAST methodology has been developed by the DTC HFI as a means to describe and understand C4i scenarios using a multiple method approach. As a demonstration of the capability of EAST it has been applied to four live scenarios involving collaborative activity amongst distributed teams. These scenarios were drawn from the rail industry, and this paper briefly describes the process-based application and outcomes of the analysis.
The IEEE 802.11 protocol is emerging as a widely used standard and has become the most mature technology for wireless local area networks (WLANs). In this paper, we focus on the tuning of the IEEE 802.11 protocol para...

EAST (Event Analysis for Systemic Teamwork) is an analysis methodology which combines seven human factors techniques in order to investigate command, control, communications, computers and intelligence (C4i) (Harris & White, 1987). The methodology has been developed by the DTC HFI. This paper focuses on two methods used in EAST, the critical decision method (CDM) and propositional networks. This paper describes the application of the methods to C4i activities for railway track maintenance.

Part family formation using fuzzy cluster analysis in Group Technology (GT) and feature recognition for tool access direction using relationship matrix in Computer Aided Process Planning (CAPP) have been presented in this paper. In the process of identifying part-families and machine groups, Fuzzy Cluster Analysis to form machine-part fuzzy relative matrix which converted into a zero-one conventional matrix. A new similarity coefficient, which involves all the entries of the machine-part fuzzy relative matrix resulting in a more realistic part family formation was suggested. The feature extraction system presented in this paper is designed to extract features from a STEP file in Boundary Representation (B-Rep) and Attributed Adjacency matrix. The system is able to automatically extract alternate tool axis directions (TADs). There is a potential applications in set-up change cost optimisation and fixture selection.

Traditionally, architecture in its design process employs physical matter, requires physical presence and relies on real world environment using conventional methods of 2D depictions such as paper and pen or 3D representations such as physical models and communicates design ideas in verbal or text-based form. The conventional design process, for example an interior design, a residential house, a commercial complex or even urban design projects, follows the same hierarchy of activities. Efforts are made to the satisfaction of both parties to give the ideas of a physical shape through sketches, drafts and models which may take weeks, even months. Finally the project gets its final shape in a working drawing, 3D visualisation or model making. This process is time consuming and somewhat redundant. In recent years technology has offered architects a new tool - the virtual environment. Architects use virtual environment increasingly as device of communication and presentation of design intensions. Virtual environment enables users to interact in real-time with design but unfortunately has not been used widely in the process of architectural design. The aim of this paper is to investigate the relationship between present design process and the emerging technology of virtual reality, establish a relationship between the two and its influence on architecture to form a new translated design process and communication, an interface between architect and client.

This paper proposes generic F0, duration and power models microprosodic components to be used in concatenative text-to-speech (TTS) synthesis. The proposed F0 and duration models also include a global component. The global component models the long-term intonation patterns in speech and the microprosody component models the sequential dependency of the acoustic correlates of speech. The microprosody model is based on a first-order Markovian model of biphone segments. Setences synthesised using the proposed F0, duration and power models gave an average MOS score of 3.76 which is 0.49 higher than that without the application of the models.
