Enhanced Metallic Properties Of Srruo3 Thin Films Via Kinetically Controlled Pulsed Laser Epitaxy, Justin K. Thompson, J. Nichols, S. Lee, S. Ryee, John H. Gruenewald, John G. Connell, Maryam Souri, J. M. Johnson, J. Hwang, M. J. Han, H. N. Lee, D. -W. Kim, Sung S. Ambrose Seo

Physics and Astronomy Faculty Publications

Metal electrodes are a universal element of all electronic devices. Conducting SrRuO₃ (SRO) epitaxial thin films have been extensively used as electrodes in complex-oxide heterostructures due to good lattice mismatches with perovskite substrates. However, when compared to SRO single crystals, SRO thin films have shown reduced conductivity and Curie temperatures (T_C), which can lead to higher Joule heating and energy loss in the devices. Here, we report that high-quality SRO thin films can be synthesized by controlling the plume dynamics and growth rate of pulsed laser epitaxy (PLE) with real-time optical spectroscopic monitoring. The SRO thin …

Mechnical Strength And Durability Of Alkali-Activated Fly Ash/Slag Concrete, Maochieh Chi

Journal of Marine Science and Technology–Taiwan

This study investigated the mechanical strength and durability of alkali-activated binders composed of blends of fly ash (FA) and ground granulated blast furnace slag. Five samples with FA/slag ratios of 100/0, 75/25, 50/50, 25/75, and 0/100 by mass were employed to prepare alkali-activated FA/slag (AAFS) concrete. Sodium oxide (Na2O) concentrations of 6% and 8% of binder weight and activator modulus ratios (mass ratio of SiO2 to Na2O) of 0.8, 1.0, and 1.23 were used to prepare alkaline activators. Test results revealed that higher slag contents, Na2O concentrations, and activator modulus ratios increased the compressive strength and splitting tensile strength of …

Effects Of Power System Stabilizer On Damping Of Inter-Area Oscillation Using Remote Signal, Van-Dien Doan, Ta-Hsiu Tseng, Pei-Hwa Huang

Journal of Marine Science and Technology–Taiwan

The inter-area oscillations in large interconnected power systems often have features of being low-frequency, lightly damped, and affecting relatively more generating units located in multiple areas. They restrict the allowable power flow on tielines and may lead to unexpected contingencies if it is not to be in proper observation. The main objective of this paper is to present a small signal stability analysis applied to Vietnam Power System which is a longitudinal network structure with the consideration of Power System Stabilizers (PSS) in operation to enhance the damping of inter-area oscillation by using local as well as remote feedback signals …

Generation Control Schemes For Preventing Overloading Of Ehv Substation Main Transformer, Yi-Kuan Ke, Pei-Hwa Huang

Journal of Marine Science and Technology–Taiwan

The main purpose of this paper is to study the control of power plant generation under outage of main transformer in the adjoining substation. The control of power plant generation aims to prevent overloading of the remaining transformer and hence to maintain system operation security. The proposed control methods include two schemes of operation on the generating units: Direct Transfer Trip (DTT) and Generation Reduction (GR). A sample local power system with an EHV substation and two generation plants is investigated and thus the two control schemes are illustrated by analyzing system power flow and system dynamics.

Mechanical Behaviors Of Piled-Raft Foundation And Diaphragm Wall In Deep Excavation Of Taipei Metropolitan, Der-Guey Lin, Wen-Tsung Liu, Jui-Ching Chou

Journal of Marine Science and Technology–Taiwan

The piled-raft foundation has been widely used in recent years to solve the low bearing capacity and the excess settlement problems of the raft foundation on the soft soil. The soft soil is reinforced by the pile and behaviors of the diaphragm wall and the raft are also modified by the pile. However, effects of the pile on the diaphragm wall and the raft have not been fully discussed in the past. In this paper, a finite element program, Plaxis-3D, is used as the numerical simulation tool. First, simulations of pile loading tests are performed to verify the input parameters …

Application Of An Extension Neural Network Method For Fault Diagnosis Of Three-Level Inverters Used In Marine Vessels, Kuei-Hsiang Chao, Yu-Ren Shen

This study proposes an extension neural network (ENN) algorithm to carry out the fault diagnosis of an inverter in a motor drive system for marine vessels. First, we use PSIM software to construct a three-level neutral point clamped (NPC) inverter, which simulates the occurrence of the fault of any power transistor in the NPC inverter. Simultaneously, we use fast Fourier transforms to transcribe the waveform of phase voltage in the time domain during the fault of any power transistor entering the spectrum in the frequency domain, looking for the corresponding characteristic spectrum during the fault of the power transistor.

Dynamic Economic Relations Among Steel Price Indices, Ming-Tao Chou

Journal of Marine Science and Technology–Taiwan

Bulk shipping is now a globalized industry, with market prices entirely dependent on the world’s economic climate. For the bulk shipping market, the steel price index is a crucial standard of reference. In a global industry, the ability to understand the international relationship between changes in information and their effects on economics can help to reduce losses caused by the uncertainty of risk. Because the types of ships and contracts used in bulk shipping are wide-ranging, market participants tend to have difficulty in determining market price changes and trends, and are therefore forced to face greater market uncertainty and volatility. …
