Feasibility study of an Integrated Program for Aerospace vehicle Design (IPAD). Volume 4: IPAD system design
The computing system design of IPAD is described and the requirements which form the basis for the system design are discussed. The system is presented in terms of a functional design description and technical design specifications. The functional design specifications give the detailed description of the system design using top-down structured programming methodology. Human behavioral characteristics, which specify the system design at the user interface, security considerations, and standards for system design, implementation, and maintenance are also part of the technical design specifications. Detailed specifications of the two most common computing system types in use by the major aerospace companies which could support the IPAD system design are presented. The report of a study to investigate migration of IPAD software between the two candidate 3rd generation host computing systems and from these systems to a 4th generation system is included
NASA/NBS (National Aeronautics and Space Administration/National Bureau of Standards) standard reference model for telerobot control system architecture (NASREM)
The document describes the NASA Standard Reference Model (NASREM) Architecture for the Space Station Telerobot Control System. It defines the functional requirements and high level specifications of the control system for the NASA space Station document for the functional specification, and a guideline for the development of the control system architecture, of the 10C Flight Telerobot Servicer. The NASREM telerobot control system architecture defines a set of standard modules and interfaces which facilitates software design, development, validation, and test, and make possible the integration of telerobotics software from a wide variety of sources. Standard interfaces also provide the software hooks necessary to incrementally upgrade future Flight Telerobot Systems as new capabilities develop in computer science, robotics, and autonomous system control
The Design and Implementation of Manufacturing Infrastructures
Merged with duplicate record 10026.1/822 on 12.04.2017 by CS (TIS)This work addresses the problem of difficulties in the implementation
of Computer Aided Production Management systems, and presents
a methodology for their implementation which significantly improves on
current practice. The methodology provides a structured approach which
leads the company through a series of strategic business decisions
which establish the context within which the solution must operate.
The work focusses attention upon the design of the whole system with
respect to the relationship between computerised functions and the
infrastructure of human elements which facilitate and govern the
system's operation. A model of the tasks involved in production
management is presented. The model is used to structure decisions
relating to the design of the infrastructure.
The research work described proceeded in two distinct stages. In the
first stage the author participated with other researchers who jointly
developed the framework of the process methodology for CAPM
implementation. This stage provides the context for the development of
the task model approach to the design of the system, which represents
the author's individual contribution (see section 1.8).
The task model can be used as a tool to identify the options available
for the way each task within production management may be executed,
giving the user a basis for the design of a particular system while not
advocating any particular solution. By the use of this approach the
user is encouraged to consider the options available and to adopt an
integrated approach which looks at all areas of production management,
not only those for which there is a pressing problem or a tempting
solution.
This work results in a contribution to the development of the process
methodology, the development of a tool in the CAPM task model and
a review of the factors involved in the design of a system including
both human and computerised elements
Feasibility study of an Integrated Program for Aerospace vehicle Design (IPAD). Volume 3: Support of the design process
The user requirements for computer support of the IPAD design process are identified. The user-system interface, language, equipment, and computational requirements are considered
Using Unified Personal Information in Workspaces
Knowledge workers (KWers) deal with personal information and use tools like, e.g., desktop workspaces to support their work. But KWer support is hindered by personal information fragmentation, i.e., applications keep a set of personal information while not interconnecting it. This thesis addresses this in the domains personal task management and meeting management by using a common unified personal information model as offered by the semantic desktop personal information management (PIM) system
Route planning algorithms: Planific@ Project
Planific@ is a route planning project for the city of
Madrid (Spain). Its main aim is to develop an intelligence system
capable of routing people from one place in the city to any other
using the public transport. In order to do this, it is necessary to
take into account such things as: time, traffic, user preferences,
etc. Before beginning to design the project is necessary to make
a comprehensive study of the variety of main known route
planning algorithms suitable to be used in this projec
Making diagnosis explicit
What is good diagnostic practice? The answer is elusive for many medical students and
equally puzzling for those trying to build effective medical decision support systems.
Much of the problem lies in the difficult of 'getting at' diagnosis. Expert diagnosticians
find it difficult to introspect on their own strategies, thus making it difficult to pass on
their expertise.Traditional knowledge acquisition methods are designed for gathering static domain
knowledge and are inappropriate for the acquisition of knowledge about the diagnos¬
tic 'task'. More advanced knowledge acquisition methodologies, particularly those which
focus on the modelling of problem-solving knowledge seem to hold more promise, but are
not sufficiently practicable to allow anyone other than a knowledge engineer to operate
directly. Given the difficulty experts have in accessing their own diagnostic strategies
what is needed is a tool which would enable diagnosticians themselves to directly formu¬
late and experiment with their own methods of diagnosis.This research describes the development of a knowledge acquisition methodology geared
specifically towards the exposition of medical diagnosis. The methodology is implemented as a toolkit enabling exploration and construction of medical diagnostic models
and production of model-based medical diagnostic support systems. The toolkit allows
someone skilled in diagnosis to articulate their diagnostic strategy so that it can be used
by those with less experience
Communicative Agents for Software Development
Software engineering is a domain characterized by intricate decision-making
processes, often relying on nuanced intuition and consultation. Recent
advancements in deep learning have started to revolutionize software
engineering practices through elaborate designs implemented at various stages
of software development. In this paper, we present an innovative paradigm that
leverages large language models (LLMs) throughout the entire software
development process, streamlining and unifying key processes through natural
language communication, thereby eliminating the need for specialized models at
each phase. At the core of this paradigm lies ChatDev, a virtual chat-powered
software development company that mirrors the established waterfall model,
meticulously dividing the development process into four distinct chronological
stages: designing, coding, testing, and documenting. Each stage engages a team
of agents, such as programmers, code reviewers, and test engineers, fostering
collaborative dialogue and facilitating a seamless workflow. The chat chain
acts as a facilitator, breaking down each stage into atomic subtasks. This
enables dual roles, allowing for proposing and validating solutions through
context-aware communication, leading to efficient resolution of specific
subtasks. The instrumental analysis of ChatDev highlights its remarkable
efficacy in software generation, enabling the completion of the entire software
development process in under seven minutes at a cost of less than one dollar.
It not only identifies and alleviates potential vulnerabilities but also
rectifies potential hallucinations while maintaining commendable efficiency and
cost-effectiveness. The potential of ChatDev unveils fresh possibilities for
integrating LLMs into the realm of software development.Comment: 25 pages, 9 figures, 2 table
