In low-cost permanent magnet synchronous motor (PMSM) drive systems, the rotor position is usually estimated based on the back-electromotive force. However, such estimation methods have the common drawback of having large errors in low-speed regions. In order to solve that drawback in the startup phase, the I-f startup method is studied as its compatibility with the FOC control structure.

The dynamic analysis is a necessity in the design, manufacturing and maintenance of structures. The analytic solutions are not available for most practical cases and the Finite Element Method (FEM) is not reliable due to the joint problem, unclear loading, material properties and numerical error. In this paper, we present a way to find modes shape of 3D Frame by FEM program using Matlab.

Human factors play an inevitable role in maintenance activities, and the occurrence of Human Errors (HEs) affects system reliability and safety, equipment performance and economic results. The high HE rate increased researchers’ attention towards Human Reliability Analysis (HRA) and HE assessment approaches. In these approaches, various environmental and individual factors influence the performance of maintenance operators affecting Human Error Probability.

The objective of the thesis is to research and develop differential algorithms. Error separating a correct text area making smaller text areas falsifies or loses the information of text or text (over-segmentation), errors include text areas in text columns or text fragments (under-segmentation).

This study examines whether analyst experience affects the relation between patent information and analyst forecast errors. U.S. Generally Accepted Accounting Principles require that firms expense all in-house research and development (R&D) costs. This means that even when R&D activities produce intangible assets with future economic benefits, firms cannot capitalize R&D costs as assets. Consequently, financial statements are largely deficient in the information they provide regarding the output of R&D activities.

This paper presents the recent improvements in the DeCART code for HTGR analysis. A new 190-group DeCART cross-section library based on ENDF/B-VII.0 was generated using the KAERI library processing system for HTGR. Two methods for the eigen-mode adjoint flux calculation were implemented. An azimuthal angle discretization method based on the Gaussian quadrature was implemented to reduce the error from the azimuthal angle discretization.

In this paper, we consider and compare several different detection techniques for the down link of a MC-CDMA system in terms of bit error rate (BER) performance. In addition, an analysis of the linear detection approach named minimum mean square error (MMSE) multi-user detection per user (MMSE MUD) is presented.

The primary aim of the thesis is to find out the second-year English majors‟ common errors on verb tenses and word choices in translating Vietnamese texts into English. The study also aims at finding causes of these problems and then suggesting some possible strategies to overcome the problems. The targeted subjects of this thesis are mainly students; nevertheless, all people who are interested in translation work can consider it as a useful reference for improving their translation skills as well.

GTP cyclohydrolase II catalyzes the first dedicated step in the biosynthesis of riboflavin and appears to be a limiting factor for the production of the vitamin by recombinantBacillus subtilisoverproducer strains. Using error-prone PCR amplification, we generated a library of theB. subtilis ribA gene selectively mutated in the GTP cyclohydrolase II domain.

Data of unknown quality are useless! All laboratory measurements contain experimental error. It is necessary to determine the magnitude of the accuracy and reliability in your measurements. Then you can make a judgment about their usefulness. Replicates - two or more determinations on the same sample Example 3-1: One student measures Fe (III) concentrations six times. The results are listed below: 19.4, 19.5, 19. 6, 19.8, 20.1, 20.3 ppm (parts per million) 6 replicates = 6 measurements The "middle" or "central" value for a group of results: Mean: average or arithmetic mean ...
