Feedforward control schemes were developed based on these prediction models. Four categories of control schemes, including feedforward, feedback, feedback with external reset, and feedforward-feedback, were proposed and evaluated by the rigorous dynamic simulation model of the sour water stripper for their dynamic responses to the sour water feed stream disturbances.

J.; Jagne, A.; Lin, H. D.; Huang, F. K.Finite-element limit analysis;slurry trenches;seismic coefficient;plastic zoneJournal of GeoEngineering 15(4), pp. 195-203For city development, more and more tall apartments and office buildings are being built with basements that require slurry supported trenches to construct diaphragm wall. In the past, some investigators have studied the stability problem of trenches. It was indicated that the trench stability analysis is a three dimensional problem due to arching effect from the finite length of the trenches. However, it is not common to account for the seismic stability analysis of trenches. This study therefore aims to conduct research on the stability of slurry supported trenches under seismic conditions. In this study, finite-element

K.bridges;collapse;scouring;soil riverbed;shear banding;rock riverbedInternational Journal of Organizational Innovation 13(1), pp.180-216Current performance design codes require that bridges be designed that they will not collapse within their design life. However, in the past twenty five years, a large number of bridges have collapsed in Taiwan, with their actual service life far shorter than their design life. This study explores the major cause of the collapse of many these bridges. The results of the study reveal the following. (1) Because riverbeds can be divided into high shear strength rock riverbeds and low shear strength soil riverbeds, the main cause of bridge collapse on a high shear strength rock riverbed is the shear band effect inducing local brittle fracture of the rock, and t

J.; Zhang, J.Okun’s law;GDP growth;unemployment rate;oil price shocksApplied Economics Letters 27(11), p.910-914This article contributes to the literature of Okun’s law by addressing an under-noticed but important problem, i.e. endogeneity. By using annual variation in the international oil price weighted with countries’ average oil net-export GDP ratios as a plausibly exogenous instrumental variable for economic growth, the two-stage least squares estimates indicate that faster real GDP growth is associated with lower overall, male and female unemployment rates, confirming the validity of Okun’s law. According to our benchmark estimate, 1 percentage point increase in economic growth leads to a 0.252 percentage point decrease in civil unemployment rate.en_US1466-4291國外SSCI;否GBR

The results demonstrate that there is an evidence of multiple bubbles in the government bond markets of United States, Germany, and Japan. The main causes of the bubbles are huge fiscal deficit caused by the massive government debt- raising in order to adopt expansionary fiscal policies, over-tightening of monetary policy and significant volatility in the global markets resulted from two oil shocks. In recent years, major developed countries have adopted expansionary fiscal policies like tax-cutting and infrastructure

He married those sources in his novels and his literary journals. This article analyzes the interplay of religious, scientific and Deleuzian imagery, guided by the figure of angels. I begin with a study of Dantec’s stylistic characteristics, his journey toward Catholic orthodoxy and his apocalyptic understanding of our world. It is in one of his novel, Cosmos Incorporated, published in 2006, that Dantec’s recipe coalesced in the most brilliant manner. The last part of this article is centered on a long passage from this novel, describing a struggle between Good and Evil, where

Chang; H.W. Lien; M.H. HungGeotechnical Engineering 51(2), p.159-165A three-dimensional finite difference analysis has been developed to estimate the foundation settlements for vertically loaded piled raft foundations. Thin-plate theory was adopted to model the finite raft with boundary effects. Alternate spring models were used to model soil resistances under the raft while the resistances of pile were model by calculating the pile stiffness from wave equation analysis. The newly proposed analysis was examined with finite element solutions. It was found that variations of soil resistance underneath the raft and the pile-soil-pile interactions are the keys to the applicability of such analysis.en0046-5828國外ESCI;否THA

A perturbed wavelet neural network (PWNN) approximator is used to online approximate the unknown nonlinear term in the VCM system dynamics. The PWNN approximator uses perturbed wavelet functions to handle the rules uncertainties like interval type-2 fuzzy sets. The structure learning ability enables the PWNN approximator to evolve its structure online. Further, the parameter learning laws and stability analysis are derived in the sense of Lyapu

The capacities of the piles were predicted using the static pile load test data with the conventional interpretation methods. The results were compared to those from APILE analyses, analytical calculations based on the Kazakhstani standard method, and the pile driving analyzer. It was shown that the highest pile capacities were obtained from the Chin interpretation and Decourt extrapolation methods.

The design process starts with defining the performance requirements including the stall speed, maximal speed, cruise altitude, absolute ceiling, and turn radius and speed. The wing loading and associated power loading are obtained based on the defined performance requirements. The wing area, UAV mass, and power requirements are determined from the endurance and payload requirements. The power requirement determines the motor size. Aerodynamics and stability designs are obtained based on the selected airfoil and obtained wing area. After completin

The results show that the ARJI-trend model not only provides a better fit for the data on the volatility dynamics of corn, soybean, and wheat futures, but also performs better in terms of out-of-sample forecasting. The U.S. dollar index and oil prices both generate significant impacts on the returns of the futures.

Furthermore, this study re-examines the relationship between REIT returns and other markets as bond and stock market. The analytical results reveal that REIT returns rise in response to increase in expected oil price and provide a good partial hedge. However, it also implicates that REIT returns have a downside risk during the period of deflation. Additionally, stock market returns reflect relevant information about REITs or real estate, and REITs are negati
