The goal of the present paper is to investigate the approximation properties of a new class of L-minimization techniques for approximating stationary HamiltonJacobi equations in one space dimension. Most approximation algorithms of Hamilton-Jacobi equations are based on monotonicity and Lax-Friedrichs approximate Hamiltonians, see e.g. Kao, Osher, and Tsai [13]. Monotonicity is very often invok...

A vision sensor is mounted on a robot to detect surrounding objects. Its mounting position and orientation must be identified, resulting in an extrinsic calibration problem. This paper presents three classes of extrinsic calibration procedures. All use closed-form solutions. The class A calibration procedure requires a reference object at a precalibrated location. The class B calibration proced...

Thanks to Christopher Gibbons and C. J. Lee for help with the simulation code, model validation, and data management. Thanks to Wenpin Tsai and three anonymous reviewers whose input significantly improved this article.

In Upper Three Runs Creek (Aiken, S.C.) and many other environments, less than 1% of bacteria visible microscopically can be cultured. Exploitation of molecular biology techniques has led to development of new methods, such as extraction of nucleic acids from soils or sediments, to study the dominant, nonculturable bacteria. The purpose of this study was to compare three published methods of DN...

With the popularization of computer and communication technologies, researchers have attempted to develop computer-assisted testing and diagnostic systems to help students improve their learning performance on the Internet. In developing a diagnostic system for detecting students’ learning problems, it is difficult for individual teachers to address the exact relationships between the test item...

LVQ (Learning Vector Quantization) has been used to impute missing group membership and stratum weights in confirmatory factor analysis (CFA) model with continuous indicators (Chen, Tsai, & Yang, 2010; Tsai & Yang, 2012). Currently, categorical questionnaires (e.g., Binary and Likert-type items) are widely used in education, business, economy, and psychology tests as well as international large...

Bent fibre-reinforced polymer (FRP) bars embedded in reinforced concrete elements resist lower forces than straight counterparts due to strength losses at the bend, and such are difficult calculate. This paper reports on an investigation into effect of section geometry bond, which led a new macro-mechanical model calculate bend capacity FRP bars. The proposed uses Tsai–Hill failure criterion ac...

In this paper, wave propagation analysis of multi-hybrid nanocomposite (MHC) reinforced doubly curved panel embedded in the viscoelastic foundation is carried out. Higher-order shear deformable theory (HSDT) utilized to express displacement kinematics. The rule mixture and modified Halpin–Tsai model are engaged provide effective material constant MHC panel. By employing Hamilton’s principle, go...
