Research ArticleOpen accessIn the abstractThe Investigation of the Relationship among Analyst Following, Managerial Ownership and Firm Valuation: From the Perspective of Agency TheoryI. J. ChenIn this study, the relationship among analyst following, managerial ownership and firm valuation is investigated from the perspective of agency theory by using a nonlinear simultaneous equation model. The data from the Taiwan stock market verify the proposed hypotheses with a nonlinear three-stage least-square procedure. The empirical results show that managerial ownership (serving an internal monitoring function) and number of … …Journal of Social Sciences, Vol. 1, Issue 1 · 31 Mar 2005 · 7,031 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Algebraic Approach to the Harmonic Oscillator Plus an Inverse Square Potential in Three DimensionsShi-Hai Dong, M. Lozada-CassouThe eigenfunctions and eigenvalues of the three-dimensional Schrödinger equation with a harmonic oscillator plus an inverse square interaction are obtained. A realization of the ladder operators for the wave functions is studied. It is found that these operators satisfy the commutation relations of an SU(1,1) group. The closed analytical expressions for the matrix elements of different functions ρ and ρd/dρ … …American Journal of Applied Sciences, Vol. 2, Issue 1 · 31 Jan 2005 · 7,279 accessesView PDFCite
Research ArticleOpen accessIn the abstractExperimental Comparison of the Known Hypotheses of the Lateral Buckling for Semi-Slender Pinned ColumnsKrzysztof MurawskiThe paper presents the comparison of experimental results obtained from tests on semi-slender columns with pinned ends made of steel R35 to simplifications and hypotheses of loss of stability by lateral buckling in elastic-plastic states of columns axially compressed by force. The Tetmajer-Jasiński’s and Johnson-Ostenfeld’s simplifications, as well as the hypotheses given by Engesser and Kármán and Shanley, Ylinen, Březina, … …International Journal of Structural Glass and Advanced Materials Research, Vol. 5, Issue 1 · 14 Apr 2021 · 6,411 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimization and Prediction of Motorcycle Injection System Performance with Feed-Forward Back-Propagation Method Artificial Neural Network (ANN)La Ode Ichlas Syahrullah, Nazaruddin SinagaThis research studied the use of Artificial Neural Network (ANN) using feed-forward back-propagation model to optimize and predict the performance of a motorcycle fuel injection systems of gasoline. The parameters such as speed, throttle position, ignition timing and injection timing is used as the input parameters. While the parameters of fuel consumption and engine torque is used as the output … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 2 · 16 Feb 2016 · 13,784 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpline Estimator for Bi-Responses and Multi-Predictors Nonparametric Regression Model in Case of Longitudinal DataAdji Achmad Rinaldo Fernandes, I Nyoman Budiantara, Bambang Widjanarko Otok, SuhartonoNonparametric regression approach is used when the shape of the curve regression is unknown. The spline estimator approach for longitudinal data can accommodate the correlation between observations within the same subject, which is not found in the cross-section data, so that the autocorrelation assumption problem can be resolved. On the other hand, with bi-responses approach, it will accommodate any correlation … …Journal of Mathematics and Statistics, Vol. 11, Issue 2 · 8 Oct 2015 · 7,337 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalysis of Interregional Commodity FlowsWirach Hirun, Sompong SirisoponsilpProblem statement: Commodity Flow Survey (CFS) was launched to collect comprehensive freight flow data throughout the kingdom of Thailand. The survey’s database is the most complete collection of commodity flow data in Thailand. The need to reveal interregional freight characteristics using available data from the CFS led to the objectives of this research. Approach: An origin destination matrix based on … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 4 · 22 Nov 2010 · 8,922 accessesView PDFCite
Research ArticleOpen accessIn the abstractImproving Protein 3D Structure Prediction Accuracy using Dense Regions Areas of Secondary Structures in the Contact MapAmer F. Al-Badarneh, Mohammad A. Khalil, Mo'taz A. Al-HamiProblem Statement: The protein folding problem is a fundamental problem in structural molecular biology. This problem describes how a protein is transformed from its primary sequence (i.e., amino acid sequence) into the three dimensional structure (3D structure) for this sequence that determines the function of the protein. The 3D structure of a protein can be represented using a square symmetrical … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 4 · 31 Dec 2008 · 7,533 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparison of the Known Hypotheses of Lateral Buckling in the Elastic-Plastic States of Thin-Walled Semi-Slender ColumnsKrzysztof MurawskiStability of structures, as known, is a challenging issue, especially in critical engineering, i.e., in designing structures which in a wrong design process could cause a catastrophe. The avoidance of possible stability troubles is mandatory. In this study, the simplifications and hypotheses of loss of stability by lateral buckling in elastic-plastic states of semi-slender columns axially compressed by force are … …International Journal of Structural Glass and Advanced Materials Research, Vol. 4, Issue 1 · 21 Dec 2020 · 6,252 accessesView PDFCite
Research ArticleOpen accessIn the abstractWeighted Integration Route to Stiffness Matrix of Quadrilaterals for Speed, Accuracy and Functionally Graded Material ApplicationSubramanian G., P.V. JeyakarthikeyanA weighted integration route with robust one-point integration (hourglass-controlled) is proposed as efficient, time saving alternative to Gauss quadrature for stiffness matrix of bilinear quadrilaterals. One-point rule relies on sampling at the center of the element to linearize the geometric transformation and average the material property over it. This enables, for a given element, explicit integration of stiffness matrix yielding … …American Journal of Applied Sciences, Vol. 15, Issue 4 · 27 Sep 2017 · 8,050 accessesView PDFCite
HypothesisOpen accessIn the abstractAnalysis of Market Orientation on Business Performance in the Multinational Service IndustriesMartin Owusu Ansah, Richard ChinomonaThe paper examined the extent of market orientation on business performance in the multinational service industries in Ghana. It applied the behavioral viewpoint of market orientation measurement using MKTOR scale as a base in eliciting information from eleven marketing managers through in - depth interview while one hundred and sixty-three marketing managers were also surveyed using structured questionnaires.
