    The problem of neural network learning to get the most convenient configuration, i.e., the vector of synaptic weights and thresholds of formal neurons creating the network, is treated. The possible errors in keeping precise the designed configuration during the realization as well as fluctuations of the configuration during the net exploitation are taken into account using the theory of tolerances...

    This work presents the theory, design, and applications of a new cell for MOS linear circuit design the linear composite MOSFET (COMFET). The approach exploits the square-law saturated drain current equation of the MOSFET, and entails the design of a linear COMFET circuit, with both its drain and source currents linearly related to its gate-source voltage, as a basic linear circuit synthesis block...

  • Computer generated Lyapunov functions for a class of nonlinear systems

    The problem of constructing Lyapunov functions for a class of nonlinear dynamical systems is considered. The problem is reduced to the construction of a polytope satisfying some conditions. A generalization of the concept of sector condition that it makes possible to evaluate a given nonlinear function by using a set of piecewise-linear functions is proposed. This improvement greatly reduces the c... View full abstract»

  • A wide-range logarithmic charge digitizer

    The digitizer described here accumulates charge from a measuring device and places it as the initial charge on the capacitor of an integrator. By measuring the time required for the charge on the capacitor to grow exponentially to a fixed threshold when positive feedback is applied, the circuit produces a digital output proportional to the logarithm of the ratio of the threshold charge to the init...

  • Self-diagnosability of multiprocessor systems with hybrid faults: diagnosis by comparison approach

    Publication Year: 1993, Page(s):355 - 358

    Considers the diagnosis of multiprocessor systems where a fault is detected by comparing the responses of two processors for the same tasks. The system-level diagnosability of such systems in the presence of permanent and intermittent faults is analyzed, assuming that the number of fault processors is no more than t and the number of intermittently faulty processors is no more than ...

  • Relaxation/Newton methods for concurrent time step solution of differential-algebraic equations in power system dynamic simulations

    A class of algorithms that exploits the concurrent solution of many time steps is presented. By applying a stable integration method, the overall algebraic-differential set of equations can be transformed into a unique algebraic problem at each time step. The dynamic behavior of the system can be obtained by solving an enlarged set of algebraic equations relative to the simultaneous solution of ma... View full abstract»

    Shows how to systematically design an inputless cellular neural network (CNN), which processes only the information present in the initial state, with prescribed stable and unstable outputs while simultaneously maximizing its robustness with respect to changes of its parameters. This is achieved by combining a generalization of previous results on CNN design with a design centering algorithm based... View full abstract»

  • Design and architecture of multiplier-free FIR filters using periodically time-varying ternary coefficients

    Publication Year: 1993, Page(s):364 - 370

    Multiplier-free realizations for FIR filters are proposed. The realizations use a periodically time-varying (PTV) system, flanked by simple units for upsampling and downsampling to achieve time-invariant multiplier-free FIR filter operation. The PTV system uses only ternary (0, ±1) coefficients, and the units before and after the PTV system use only power-of-two scalers. Therefore, the real... View full abstract»
