This paper discusses an ongoing adaptation of a decision making synchronous/asynchronous common environment for computer supported cooperative work (SACE-CSCW) for a distributed videoconferencing multimedia/ hypermedia concurrent engineering (CE) system to run over the Web. The SACE environment is being redesigned to incorporate this application area and its actual models are being extended to ...

Manufacturing systems can be very complex and are often costly to develop and operate. Simulation technology has been shown to be an effective tool for optimizing manufacturing system design, operations, and maintenance procedures. However, each manufacturing simulation is usually developed to address a specific set of industrial issues, and may only apply to a small portion of a complex manufa...

Development assistance has a chequered past, in large part because planning for development assistance is historically such a fractured enterprise internally, and so disassociated from development assistance recipients’ assets and needs. The authors of environment-shaping offer an alternative development programme planning methodology that highlights above all else the ever-important relationsh...

Despite the significance of matched devices in analog circuit design, mismatch modeling for design application has been lacking. This paper addresses misconceptions about MOSFET mismatch for analog design. t mismatch does not follow a simplistic 1 ( area) law, especially for wide/short and narrow/long devices, which are common geometries in analog circuits. Further, t and gain factor are not ap...

In this paper we discuss collaborative version control issues in a hypertext architecture which has been de ned using an agent-level design metaphor. Within this perspective all the basic activities which rule the functioning of the hypertext are formulated in terms of collaborative, parallel mechanisms, which organize global tasks disseminating knowledge and duties over a population of computa...

This paper focuses on a supporting strategy for enhancing distributed and computer-mediated group programming learning. Based on a real-world research setting that started two decades ago, we have exploited a particular context characterized by: (i) a close analysis of artifacts produced by learners; (ii) a collaborative approach to learning, combined with (iii) a team-based approach to program...

We introduce a novel approach to the problem of localizing objects in an image and estimating their fine-pose. Given exact CAD models, and a few real training images with aligned models, we propose to leverage the geometric information from CAD models and appearance information from real images to learn a model that can accurately estimate fine pose in real images. Specifically, we propose FPM,...

Collaborative design can create added value in the design and production process by bringing the benefit of team work and cooperation in a concurrent and coordinated manner. However, distributed design knowledge and product data make the design process cumbersome. To facilitate collaborative design, an agent-based intelligent CAD platform is implemented. Intelligent agents are applied to the co...

Scientific research is a vanguard domain of human activity. Researchers aim for a systematic, objective approach, but also for pushing forward the boundaries of knowledge through the use of ever-more advanced instruments and techniques. Computer simulations represent such scientific instruments, capable of harvesting information in response to questions beyond the scope of traditional experimen...

Explanation-based learning (EBL) systems have established their applicability to a wide variety of tasks. However, in despite intensive research, several problems relating to explanation-based learning have remained by and large open. This paper describes an approach to the problems of generalizing number and learning eeciently from multiple examples. The basic insight upon which the technique ...
