A Delay-Dependent Approach To Robust Stability For Uncertain Stochastic Neural Networks With Time-Varying Delay, Chien-Yu Lu, Chin-Wen Liao, Koan-Yuh Chang, Wen-Jer Chang Feb 2010

A Delay-Dependent Approach To Robust Stability For Uncertain Stochastic Neural Networks With Time-Varying Delay, Chien-Yu Lu, Chin-Wen Liao, Koan-Yuh Chang, Wen-Jer Chang

Journal of Marine Science and Technology–Taiwan

This paper investigates the global delay-dependent robust stability in the mean square for uncertain stochastic neural networks with time-varying delay. The activation functions are assumed to be globally Lipschitz continuous. Based on a linear matrix inequality approach, globally delay-dependent robust stability criterion is derived by introducing some relaxation matrices which, when chosen properly, lead to a less conservative result. Two numerical examples are given to illustrate the effectiveness of the method.

Estimation Model Of Transformer Iron Loss Using Neural Network, Tai-Ken Lu, Chien-Ta Yeh, Min-Doon Dirn

Journal of Marine Science and Technology–Taiwan

When we want to calculate the transformer iron loss in operation, in addition to considering the nonlinear hysteretic phenomenon of transformer itself and the natural unbalanced characteristic, the actual situation that the transformer is operated under three phase unbalance state should also be considered. This results in very non-regular change of the transformer iron loss, and the accuracy of the polynomial model that is commonly used to estimate the iron loss of the transformer in the past is thus reduced. Since neural network has parallel processing capability, which can process highly nonlinear function problem, hence, in this study, we try …

Experimental Study Of Deformation Behavior And Fatigue Life Of Aisi 304 Stainless Steel Under An Asymmetric Cyclic Loading, Yung-Chuan Chiou

Journal of Marine Science and Technology–Taiwan

In this study, the cyclic deformation behavior and fatigue life of AISI 304 stainless steel with or without mean strains were studied experimentally. In the case of fully reversal cyclic straining, it is found that there is no virtually difference between the cyclic stress response curves in tension and in compression at strain amplitude of higher than 0.30%. At the controlled strain amplitude of 0.25% and 0.30%, the two cyclic stress response curves are separated quite widely. The degree of asymmetry can be attributed to the anisotropic behavior of AISI 304 stainless steel. Further, the experimental results indicate that AISI …

Effect Of Commutation Failures On Torsional Vibrations Of A Turbine Generator Nearby An Hvdc Link, Chi-Hshiung Lin

Journal of Marine Science and Technology–Taiwan

For an HVDC system, it is studied the torsional vibrations induced on the inverter side turbine generators due to a rectifier side ac faults. It is found there may be up to several times difference in the torsional torques induced at the turbine shafts and blades for the same fault, depending on the inverter commutation behavior. Further, if a single-phase-to-ground fault takes place with the commutation failure, it might cause a more serious impact on the turbine generator unit than a threephase-to-ground fault without commutation failure.

Fabrication of silicon waveguides without performing any silicon etching is demonstrated. The silicon waveguides are defined by the concept of “selective oxidation”. The experiment demonstrates that the waveguides formed by selective oxidation produce ultra-smooth sidewalls since etching of silicon is avoided. The Si etching usually creates damage from ion bombardment and chemical reactions that occur during plasma etching. The final waveguide also demonstrates very low light low based on optical testing which shows that no light scattering is observed. The final waveguide has a width of 1.5 μm and a height of ~80 nm.
