Characterization of human and instrument related measurement errors

Measurement is the act or the result of a quantitative comparison between a given quantity and a quantity of the same kind chosen as a unit. It is generally agreed that all measurements contain errors. In a measuring system where both a measuring instrument and a human being taking the measurement using a preset process, the measurement error could be due to the instrument, the process or the human being involved. The first part of the study is devoted to understanding the human errors in measurement. For that, selected person related and selected work related factors that could affect measurement errors have been identified. Though these are well known, the exact extent of the error and the extent of effect of different factors on human errors in measurement are less reported. Characterization of human errors in measurement is done by conducting an experimental study using different subjects, where the factors were changed one at a time and the measurements made by them recorded. From the pre‐experiment survey research studies, it is observed that the respondents could not give the correct answers to questions related to the correct values [extent] of human related measurement errors. This confirmed the fears expressed regarding lack of knowledge about the extent of human related measurement errors among professionals associated with quality. But in postexperiment phase of survey study, it is observed that the answers regarding the extent of human related measurement errors has improved significantly since the answer choices were provided based on the experimental study. It is hoped that this work will help users of measurement in practice to better understand and manage the phenomena of human related errors in measurement.

Analytical Study of Typographical Errors in OPACS and Corrective Measures

The present study is an attempt to highlight the problem of typographical errors in OPACS. The errors made while typing catalogue entries as well as importing bibliographical records from other libraries exist unnoticed by librarians resulting the non-retrieval of available records and affecting the quality of OPACs. This paper follows previous research on the topic mainly by Jeffrey Beall and Terry Ballard. The word “management” was chosen from the list of likely to be misspelled words identified by previous research. It was found that the word is wrongly entered in several forms in local, national and international OPACs justifying the observations of Ballard that typos occur in almost everywhere. Though there are lots of corrective measures proposed and are in use, the study asserts the fact that human effort is needed to get rid of the problem. The paper is also an invitation to the library professionals and system designers to construct a strategy to solve the issue

A Realization Of An Fpga Sub System For Reducing Odometric Localization Errors In Wheeled Mobile Robots

This paper introduces a simple and efficient method and its implementation in an FPGA for reducing the odometric localization errors caused by over count readings of an optical encoder based odometric system in a mobile robot due to wheel-slippage and terrain irregularities. The detection and correction is based on redundant encoder measurements. The method suggested relies on the fact that the wheel slippage or terrain irregularities cause more count readings from the encoder than what corresponds to the actual distance travelled by the vehicle. The standard quadrature technique is used to obtain four counts in each encoder period. In this work a three-wheeled mobile robot vehicle with one driving-steering wheel and two-fixed rear wheels in-axis, fitted with incremental optical encoders is considered. The CORDIC algorithm has been used for the computation of sine and cosine terms in the update equations. The results presented demonstrate the effectiveness of the technique

Test for basis-set errors in relativistic Dirac-Fock-Slater calculations with a numerical AO-DFS-basis

A fully relativistic four-component Dirac-Fock-Slater program for diatomics, with numerically given AO's as basis functions is presented. We discuss the problem of the errors due to the finite basis-set, and due to the influence of the negative energy solutions of the Dirac Hamiltonian. The negative continuum contributions are found to be very small.

Self-medication and related terms: a conceptual reflection

Introduction: self-medication has become a growing practice in the world population. This phenomenon has been promoted as a form of self-care, with a positive impact on reducing spending in health systems, however there is concern about the potential negative effects related to inadequate diagnosis and treatment, which can affect health of individuals. This dual perception of the phenomenon is partly related to a variety of terms and concepts used, that make difficult its theoretical and empirical approach. Harmonization of the definitions involved is required in order to make adequate epidemiological comparisons. Objectives: analyze the concept of self medication and related terms from the definitions in the literature of the subject. Conclusions: in the last four decades it has been an evolution of both the wording and the definitions related to self-medication, from a very simple concept that implies the absence of prescription, to more complex ones that encompass very diverse behaviors, even those mediated by an act of prescription but not followed or not completed by the patient. Additionally the conceptual proliferation seen, justify the ordering of the terms related to self-medication. This paper presents a proposal for classification in four groups: a. self-medication, b. self care, c. pharmaceutical preparations and medicines, and d. prescription. This proposal should facilitate the exploration and analysis of the phenomenon and allow future theoretical approaches.

L'anàlisi dels errors de puntuació. 'El análisis de los errores de puntuación'.

En este artículo se presenta el análisis de los errores de puntuación realizado sobre un corpus formado a partir de exámenes de Selectividad. El estudio de los errores de puntuación que los estudiantes hacen en los escritos académicos que producen permite averiguar cuales son y en qué grado consiguen este tipo de errores.Estos datos permiten reflexionar sobre las representaciones que tienen los estudiantes sobre la puntuación, a la vez que permite hacerlo sobre la propia naturaleza de la puntuación. Desde este conocimiento es posible establecer una imagen más fiel de las carencias que presentan los estudiantes y de cómo se puede orientar la práctica educativa para erradicar estos errores de sus escritos.

Children's errors in mathematics : understanding common misconceptions in primary schools.

Manual diseñado para ayudar a los profesores de primaria a identificar en los niños sus conceptos erróneos en matemáticas. Considera tres perspectivas diferentes: el nivel del plan de estudios, el nivel del aula y el nivel de cada alumno. La comprensión de cómo los niños construyen su conocimiento matemático y los errores que cometen, permite identificar y explicar por qué ocurre el error. También permite adelantarse a conceptos erróneos habituales y a planificar las lecciones. Tiene un índice con referencias cruzadas para el programa nacional británico.
