In this paper presents a technique for developing the computational efficiency in simulating double output induction generators (DOIG) with two rotor circuits where stator transients are to be included. Iterative decomposition is used to separate the flux– Linkage equations into decoupled fast and slow subsystems, after which the model order of the fast subsystems is reduced by neglecting the h...

Navigation guided by natural language instructions is particularly suitable for Domestic Service Robots that interacts naturally with users. This task involves the prediction of a sequence actions leads to specified destination given navigation instruction. The thus requires understanding instructions, such as “Walk out bathroom and wait on stairs are right”. Visual Language remains challenging...

The phase diagram of quarter-hole-doped perovskite manganites is investigated using the double-exchange model. An exotic striped type-II multiferroic phase, where 25% of the nearest-neighbor spin couplings are orthogonal to each other, is found in the narrow-bandwidth region. Comparing with the spiral-spin ordering phase of undoped manganites, the multiferroic Curie temperature of the new phase...

We have analyzed the phenomenon of stochastic resonance in a double well potential driven by a colored non Gaussian noise. Using a path-integral approach we have obtained a consistent Markovian approximation that enables us to get, through the two state theory, analytical expressions for the signal-to-noise ratio, nding an enhancement of this quantity when the system departs from Gaussian behav...

A disadvantage of double-samplingΣ∆ ADC’s is their sensitivity to path mismatch. Recently, an approach to solve this problem was presented. It consists of modifying the noise transfer function (NTF) of the modulator such that it has a zero at the Nyquist frequency, next to those in the baseband. Unfortunately, no systematic design strategy for such ADC’s is available. In this work, we present s...

A double sampled second order ΣΔ modulator with an analog look ahead (ALA) approach is presented. The proposed architecture provides an extra clock period to be used for the quantization. The feedforward path in both integrators allows the further reduction of the output voltage swing, relaxing also the slew-rate requirements of the op-amps. Moreover, the modulator enables the reduction of the ...

Adaptive echo cancellers with two-path algorithm are applied to avoid the false adaptation during the double-talk situation. In the two-path algorithm, several transfer logic solutions have been proposed to control the filter update. This paper presents an improved transfer logic solution. It improves the convergence speed of the two-path algorithm, and allows the reduction of the memory elemen...

In 1997, Ng and Schultz introduced the idea of cycle orderability. For a positive integer k, a graph G is k-ordered if for every ordered sequence of k vertices, there is a cycle that encounters the vertices of the sequence in the given order. If the cycle is also a hamiltonian cycle, then G is said to be k-ordered hamiltonian. We give minimum degree conditions and sum of degree conditions for n...
