Acquisition, representation and rule generation for procedural knowledge

Current research into the design and continuing development of a system for the acquisition of procedural knowledge, its representation in useful forms, and proposed methods for automated C Language Integrated Production System (CLIPS) rule generation is discussed. The Task Analysis and Rule Generation Tool (TARGET) is intended to permit experts, individually or collectively, to visually describe and refine procedural tasks. The system is designed to represent the acquired knowledge in the form of graphical objects with the capacity for generating production rules in CLIPS. The generated rules can then be integrated into applications such as NASA's Intelligent Computer Aided Training (ICAT) architecture. Also described are proposed methods for use in translating the graphical and intermediate knowledge representations into CLIPS rules

Simultaneous multithreading: Operating system perspective

Developing CPU architecture is a very complicated, iterative process that requires significant time and money investments. The motivation for this work is to find ways to decreases the amount of time and money needed for the development of hardware architectures. The main problem is that it is very difficult to determine the performance of the architecture, since it is impossible to take any performance measurements untill upon completion of the development process. Consecutively, it is impossible to improve the performance of the product or to predict the influence of different parts of the architecture on the architecture\u27s overall performance. Another problem is that this type of development does not allow for the developed system to be reconfigured or altered without complete re-development. . The solution to the problems mentioned above is the software simulators that allow researching the architecture before even starting to cut the silicon.. Simultaneous multithreading (SMT) is a modern approach to CPU design. This technique increases the system throughput by decreasing both total instruction delay and stall times of the CPU. The gain in performance of a typical SMT processor is achieved by allowing the instructions from several threads to be fetched by an operating system into the CPU simultaneously. In order to function successfully the CPU needs software support. In modern computer systems the influence of an operating system on overall system performance can no longer be ignored. It is important to understand that the union of the CPU and the supporting operating system and their interdependency determines the overall performance of any computer system. In the system that has been implemented on hardware level such analysis is impossible, since the hardware system is neither flexible nor configurable. However, in the SMT architecture, the system is capable of performing some useful work even if a task has generated an error. A wide range of simulators is described in the literature, and a lot of them are publicly accessible. The main goal of this work is to modify an existing SEVIOS/Topsy simulator to achieve a simple, configurable, publicly accessible SMT SEVIOS/Topsy simulator that must also include an SMT Topsy.. The simulator should demonstrate the fetching process of the SMT MIPS, as well as scheduling aspects of the CPU and the operating system integrated environment.. This work covers a broad range of aspects, among which are: 1) Completion of SMT MIPS and SMT Topsy specifications; 2) Integration of MXS into SIMOS/Topsy; 3) Modifications to the fetching unit of MXS that allow to support SMT; 4) Addition of SMT support to Topsy;; This work uses Topsy/R4000 simulator developed at Swiss Federal Institute of Technology, and the MXS (R10000) part of the SimOS simulator developed at Stanford University. Development process utilizes C high-level language, Intel and MIPS assembly languages. The result of this work is a development of a complete computer system software simulator. The simulator allows taking performance measurements and reconfiguration of SMT Topsy and the fetching unit of the SMT MXS. The simulator is modular: that is any of its parts can be substituted with other parts that perform similar functionality. It also means that the whole simulator can be integrated into a larger scale simulation project. The development of this simulator significantly decreases the amount of time and money needed for the development of hardware architectures and provides new ways in researching the influence of an operating system on the performance of the computer system as a whole

Definition, analysis and development of an optical data distribution network for integrated avionics and control systems. Part 2: Component development and system integration

Fiber optic transmission is emerging as an attractive concept in data distribution onboard civil aircraft. Development of an Optical Data Distribution Network for Integrated Avionics and Control Systems for commercial aircraft will provide a data distribution network that gives freedom from EMI-RFI and ground loop problems, eliminates crosstalk and short circuits, provides protection and immunity from lightning induced transients and give a large bandwidth data transmission capability. In addition there is a potential for significantly reducing the weight and increasing the reliability over conventional data distribution networks. Wavelength Division Multiplexing (WDM) is a candidate method for data communication between the various avionic subsystems. With WDM all systems could conceptually communicate with each other without time sharing and requiring complicated coding schemes for each computer and subsystem to recognize a message. However, the state of the art of optical technology limits the application of fiber optics in advanced integrated avionics and control systems. Therefore, it is necessary to address the architecture for a fiber optics data distribution system for integrated avionics and control systems as well as develop prototype components and systems

Computer interfaces for the visually impaired

Information access via computer terminals extends to blind and low vision persons employed in many technical and nontechnical disciplines. Two aspects are detailed of providing computer technology for persons with a vision related handicap. First, research into the most effective means of integrating existing adaptive technologies into information systems was made. This was conducted to integrate off the shelf products with adaptive equipment for cohesive integrated information processing systems. Details are included that describe the type of functionality required in software to facilitate its incorporation into a speech and/or braille system. The second aspect is research into providing audible and tactile interfaces to graphics based interfaces. Parameters are included for the design and development of the Mercator Project. The project will develop a prototype system for audible access to graphics based interfaces. The system is being built within the public domain architecture of X windows to show that it is possible to provide access to text based applications within a graphical environment. This information will be valuable to suppliers to ADP equipment since new legislation requires manufacturers to provide electronic access to the visually impaired

Information systems architecture for fire emergency response

Purpose There has been a lack of meaningful information systems architecture, which comprehensively conceptualise the essential components and functionality of an information system for fire emergency response addressing needs of different job roles. This study proposes a comprehensive information systems architecture which would best support four of the key fire-fighter job roles. Design The study has built on the outcomes of two previous preliminary studies on information and human-computer interaction needs of core fire fighter job roles. Scenario based action research was conducted with fire fighters in a range of roles, to evaluate human computer interaction needs while using various technology platforms. Findings Several key themes were identified and led us to propose several layers of an integrated architecture, their composition and interactions. Research limitations The selected fire scenarios may not represent every type of fire expected in high risk built environments. Practical implications The current paper represents a shared discussion among end users, system architects and designers, to understand and improve essential components. It, therefore, provides a reference point for the development of an information system architecture for fire emergency response. Originality The proposed information system architecture is novel because it outlines specific architectural elements required to meet the specific situation awareness needs of four of the key firefighters job roles

An Approach to Semi-Autonomous Indoor Drone System: Software Architecture and Integration Testing

To address these problems, we establish a semi-autonomous functionality by removing the RC transmitter, and remotely connecting the Drone System to track status and executing user-based input commands. In order to resolve the limitation in hardware connections on the Flight Controller, we integrated the sonar sensor into a companion computer, from where the data is continuously fed to an embedded system through MAVLink (Micro Aerial Vehicle Link) network communication protocol. In this study, we also implemented a modular architecture which enables scalable integration of sensor modules into the Drone System to streamline the process of development, deployment, testing and debugging
