The Smart Grid Technology Development Strategy of Taiwan  [PDF]
Faa-Jeng Lin, Yenhaw Chen, Su-Ying Lu, Yvonne Hsu
Smart Grid and Renewable Energy (SGRE) , 2016, DOI: 10.4236/sgre.2016.75012
Abstract: In Taiwan, in corresponding to the policy of reducing CO2 emission, reforming current energy structure, and saving energy, the National Energy Program (NEP)-Smart Grid General Project Phase 1 was implemented. The objectives of this project are meant to enhance the robustness of the power grid, reduce greenhouse gas emission, increase the penetration rate of renewable energy and develop smart grid industry in Taiwan. This study will introduce the positioning of the Smart Grid General Project among overall smart grid development, the results of Phase 1, the smart grid technology commercialization process of Phase 2, and the promotion model with collaboration between industry, universities and research units.
Probability-Based Seismic Performance Evaluation for Buildings  [PDF]
Jeng-Hsiang Lin
World Journal of Engineering and Technology (WJET) , 2016, DOI: 10.4236/wjet.2016.43C002
Abstract:
Recent developments in earthquake engineering indicate that probabilistic seismic risk analysis (PSRA) is becoming increasingly useful for the evaluation of structural per-formance in accordance with building codes. In recent years, the field of seismic resis-tance design has been undergoing a critical shift in focus from strength to performance. However, current earthquake resistant design procedures do not relate building performance to probability. A lack of sufficient empirical data has highlighted gaps in this research. This study integrated results from the analysis of structural fragility and seismic hazard in Taiwan to perform PSRA to examine the effectiveness of building code in mitigating the risks associated with earthquakes. Factors taken into account included the effect of construction materials, building height, and building age. The results of this study show that the probability of exceeding damage associated with the CP level in buildings of light steel, pre-cast concrete, and masonry, exceeds 2%. These buildings fail to meet the performance objectives outlined in FEMA-273.
Nonexistence of Nontrivial Solutions with Decay Order for a Biharmonic P-Laplacian Equation and System  [PDF]
Jeng-Eng Lin
Applied Mathematics (AM) , 2017, DOI: 10.4236/am.2017.87072
Abstract: We use the Morawetz multiplier to show that there are no nontrivial solutions of certain decay order for a biharmonic equation with a p-Laplacian term and a system of coupled biharmonic equations with p-Laplacian terms in the entire Euclidean space.
Role of proton pump inhibitors in the management of peptic ulcer bleeding
Hwai-Jeng Lin
World Journal of Gastrointestinal Pharmacology and Therapeutics , 2010,
Abstract: Peptic ulcer bleeding is a serious medical problem with significant morbidity and mortality. Endoscopic therapy significantly reduces further bleeding, surgery and mortality in patients with bleeding peptic ulcers and is now recommended as the first hemostatic modality for these patients. The efficacy of large-dose proton pump inhibitor (PPI) therapy in reducing re-bleeding after endoscopic therapy has been supported by evidence derived from randomized controlled trials. It may be premature to recommend small-dose intravenous injection PPI after endoscopic hemostasis in patients with bleeding ulcers. An updated systematic review shows that PPI therapy before endoscopy significantly reduces the proportion with major stigmata and requirement for endoscopic therapy at index endoscopy. Some studies show that there is no significant difference between oral and intravenous PPIs in raising intragastric pH. However, clinical data is lacking in patients with peptic ulcer bleeding to date.

Extension of Long-Staehler’s Model on Optimal Export Tax in the Case of Privatization  [PDF]
Tsaur-Chin Wu, Jeng-Wen Lin
Modern Economy (ME) , 2015, DOI: 10.4236/me.2015.65053
Abstract: This paper extends Long and Staehler’s model and studies optimal export tax in the case of privatization. The authors find that optimal export tax increases with the degree of privatization if product differentiation exists. The authors provide a counterexample to Long and Staehler’s model and reach a different conclusion. This finding emphasizes that the relationship between the variables of optimal export tax and conditions of asymmetric cost and product differentiation is quite different from Long and Staehler’s model. Since optimal export tax is endogenous in the model, the authors also consider the potential endogeneity of privatization decision, which is an important issue in a traditional mixed duopoly analysis.
Applying Analytic Network Process to the Selection of Construction Projects  [PDF]
Jeng-Hsiang Lin, Chien-Jou Yang
Open Journal of Social Sciences (JSS) , 2016, DOI: 10.4236/jss.2016.43007
Abstract:

Selecting a construction project is relatively complex as it involves multi-criteria decision-making (MCDM). To solve this problem, this study used the fuzzy Delphi method to identify six key factors of influence on selection outcomes and established evaluation criteria based on these factors. After employing analytic network process (ANP) to identify relationships between the objective, the evaluation criteria and the candidate projects, this study developed a decision-making model to resolve the difficulty of selecting an optimum construction project and conducted weighted analysis of the candidate projects using the quantitative procedures of ANP. Lastly, an empirical case study was used to verify the proposed method. The results of this study show that ANP can be used to build an effective decision-making model capable of analyzing candidate construction projects and selecting the optimal one.

Combined Effects of Thermal Diffusion and Diffusion-Thermo Effects on Transient MHD Natural Convection and Mass Transfer Flow in a Vertical Channel with Thermal Radiation  [PDF]
Isah Bala Yabo, Basant Kumar Jha, Jeng-Eng Lin
Applied Mathematics (AM) , 2016, DOI: 10.4236/am.2016.718185
Abstract: We study the nonlinear coupled evolution equations which model the transient MHD natural convection and mass transfer flow of viscous, incompressible and electrically conducting fluid between two infinite vertical plates in the presence of the transversal magnetic field, thermal radiation, thermal diffusion and diffusion-thermo effects. Both analytical and numerical methods are used for this study.
Transient Natural Convection in an Annulus with Thermal Radiation  [PDF]
Basant Kumar Jha, Isah Bala Yabo, Jeng-Eng Lin
Applied Mathematics (AM) , 2017, DOI: 10.4236/am.2017.89100
Abstract:
The interaction of transient fully developed natural convection flow with thermal radiation inside a vertical annulus is analyzed both analytically and numerically. The Rosseland approximation is used to describe the radiative heat flux in the energy equation. The mathematical model capturing the present physical situation is highly non-linear due to the presence of radiation effect. The solution of transient model is obtained by implicit finite difference method. To check accuracy of the numerical solution, steady state solution for energy and momentum equations are derived analytically using perturbation series method. Skin-friction and Nusselt number at the outer surface of inner cylinder as well as inner surface of the outer cylinder are obtained. Selected sets of graphical results illustrating the effects of various controlling parameters involved in the problem on flow formation are discussed.
Measuring Railway Efficiencies with Consideration of Input Congestion  [PDF]
Erwin T. J. Lin, Lawrence W. Lan, Jeng-Cheng Chang
Journal of Transportation Technologies (JTTs) , 2012, DOI: 10.4236/jtts.2012.24034
Abstract: Input congestion very likely existed in rail transport. However, early works measuring the rail transport efficiencies rarely took the input congestion into account; hence, the proposed strategies for enhancing efficiencies can be misleading. This study revisited the rail transport efficiencies with consideration of input congestion. We employed data envelopment analysis extension method to investigate the input congestion for some selected 24 European Union (EU) railways in 2006. The results indicated that there is no strong congestion in these 24 railways. However, 12 railways have been diagnosed with weak congestion in the available capacity of freight transport as well as the number of locomotives, 7 railways in the available capacity of passenger transport, and 4 railways in the number of employees. Based on our findings, the managerial implication is to contract the available capacity of freight transport (tonnages) as the most critical strategy, rather than laying-off the excess number of employees suggested by most previous studies, which did not consider the input congestion effects while measuring the rail transport efficiencies.
