    Artificial intelligence (AI) is the scientific study of occurrent and dispositional mentation with a view to providing adequate computational models of the mind. As a science, AI is committed to an objective, third-person verifiable account of reality. If, however, there are aspects of our mentation that are irreducibly non-physical and subjective, then those aspects are forever closed to any comp... View full abstract»

    One of the fundamental challenges facing broadband information transport is to determine congestion control strategies to support multiple classes of traffic in the asynchronous transfer mode (ATM) based networks. Monitoring the buffer status is the most commonly used mechanism to detect congestions in ATM networks. However, in static feedback controllers defining the threshold of the buffer for c...

    Firefighters and paramedics in the fire services offer an excellent audience for computer-based instruction (CBI). They are on call for fixed amounts of time, some of which is available for self-paced study. These individuals also must take many hours of mandated courses (e.g. on blood borne pathogens) for which they meet in classrooms and are not available for their regular jobs. Many mandated co...

    Recent theoretical results support that decreasing the number of free parameters in a neural network (i.e., weights) can improve generalization. The importance of these results has triggered the development of many approaches which try to determine an “appropriate” network size for a given problem. Although it has been demonstrated that most of the approaches manage to find small size ... View full abstract»

    The finite difference time domain (FDTD) method of solving electromagnetic problems is gaining popularity. This is due to the simplicity of the technique, and to its ability to solve very complicated problems. Scattering from an infinitely long perfect electrical conductor (PEC) cylinder is studied to show how accuracy varies with field sampling point location. It is shown that accuracy varies wit...

  • A trail-based deadlock-free routing scheme in wormhole-routed networks

    Publication Year: 1995, Page(s):285 - 288
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (284 KB)

    This paper focuses on deadlock-free routing in wormhole-routed networks. A trail-based model is proposed to support deadlock-free routing in any networks with node degree no less than four. Basically, given a graph G representing an interconnection network, a walk in G is a finite sequence of edges. The trail-based model generalizes the trip-based model proposed earlier and it eliminates the need ... View full abstract»

    The problem of stabilization and null controllability of open loop unstable discrete-time multi-input systems with constraints on the states and the control was addressed in a previous paper (see Proc. 32nd IEEE Conf. Decision and Control, San Antonio, TX, USA, IEEE, p.3473-8, 1994). In the present paper we analyze some of the properties of the suggested quadratically saturating control, and exten...

    Concerns cache designs using replacement strategies to provide the high performance required by fast CPUs. We propose a new replacement technique that uses some heuristic to detect loop structures in the reference patterns. Initially, the proposed technique uses the least recently used (LRU) strategy. Once a loop has been detected, all the references, which would result in poor performance if they... View full abstract»

    Uninterruptible power supplies present a method to quickly detect a loss of power and replace the defective power source before any damage or corruption occurs. Using an inverter circuit to generate a square wave for a DC source can supply a crude approximation of an AC wave form. Obviously, the harmonic content is high and voltage regulation and current limiting are essentially non-existent. The ... View full abstract»

    End-point detection of a speech signal is an important process in isolated-word recognition. Several approaches were suggested to isolate speech signal from the back-ground noise. One such approach is using energy and zero crossing rate. In the paper, a variation of this algorithm is considered for hardware implementations for both on-the-fly (real time applications) and off-the-fly (non-real time... View full abstract»

    This paper is concerned with the machine construction of printed circuit boards (PCBs). The critical steps in this process include path planning, drilling, and part placement or insertion. To enhance production speed it is important that an optimal (or near-optimal) assembly sequence can be found which performs these tasks in a minimal time. The general PCB assembly problem is at least as complex ... View full abstract»

    As integrated circuit feature sizes decrease and clock speeds increase, the problems of coupling between adjacent microstrip transmission lines and devices become more severe. This is especially true in communication circuits, such as pagers and cellular communications devices. In these cases the simultaneous presence of RF and digital circuitry increases the severity of coupling problems. In the ... View full abstract»

    The modular concept of microcontroller design provides the means whereby each module can have it's own local microengine or state machine. The main CPU communicates with the modules through dual access memory, issuing commands to semi-intelligent state machines or writing directly to registers in the module. Once a module has been given a command sequence, the peripheral can act autonomously from ... View full abstract»
