In this paper, we discuss the importance of measurement in quantum mechanics and the so-called measurement problem. Any quantum system can be described as a linear combination of eigenstates of an operator representing a physical quantity; this means that... see more

The basic idea of quantum mechanics is that the property of any system can be in a state of superposition of various possibilities (or eigen states). This state of superposition is also known as wave function and it evolves linearly with time in a determi... see more

Purpose – this paper aims to develop a non-stationary hypercube model capable of uniting the properties that models for both problems seek (location and shift-scheduling problems).Theoretical framework – We present the proposed model using a mixed discret... see more

Relación contenido-evaluación del aprendizaje en Geografía de la Salud /Relation content-evaluation of learning in Geography of Health Relación contenido-evaluación del aprendizaje en Geografía de la Salud /Relation content-evaluation of learning in Geography of HealthObjetivo: valorar los procedimientos seguidos para el establecimiento de la relación objetivo-contenido-evaluación dentro del Proceso Enseñanza Aprendizaje (PEA) de la asignatura Geografía de la Salud, en la preparatoria de la Escuela Latinoamericana de Medicina.Métodos: se realizó un estudio descriptivo transversal a una muestra de 80 estudiantes y cinco profesores, entre los cursos 2015-2017. Se emplearon los métodos teóricos: histórico-lógico, análisis-síntesis y análisis documental y como empíricos: la observación directa y abierta y la encuesta. El método matemático se empleó para valorar los resultados desde el análisis porcentual.Resultados: el control a clases y la encuesta a estudiantes evidenciaron la existencia de dificultades para lograr una eficiente relación objetivo-contenidos-evaluación del aprendizaje. Se corroboraron dificultades con la orientación docente de los objetivos, pobre trabajo con esencialidades del contenido y el sobredimensionamiento de la pregunta escrita como forma de evaluación.Conclusiones: en la asignatura Geografía de la Salud subsisten limitaciones en la relación objetivo-contenidoevaluación,expresado en: la orientación continua del objetivo dentro del PEA, la determinación de esencialidades de los contenidos y el nivel de asimilación con que se imparten, la correspondencia entre contenidos impartidos y las evaluaciones realizadas y el sobredimensionamiento de la pregunta escrita dentro de la evaluación sistemática.El diseño de acciones dentro del plan docente metodológico donde se aborde estas problemáticas puede ser una vía que contribuya a la preparación de los docentes para un desarrollo más eficiente del PEA.ABSTRACTObjective: to evaluate the processing’s solid to the establishment of objective-content-evaluation relationship in the PEA of Geography of Health subject, in the pre academic course of Latin American Medicine School.Methods: a cross descriptive study to 80 students sample and five academicians was carried out between 2015-2017 academical years. The theoretical methods: historical-logical, analysis-synthesis and documental analysis were used, as empirical: the direct open observation and the questionnaire. The mathematics method was used to evaluate the results since the percentage analysis.Results: the class control and the questionnaire to students, evidenced the existence of difficulties to achieve the efficient re-lationship objective-content-evaluation of learning. Difficulties with academicals orientation of the objectives were confirmed, poor work with essentials of content and the over measurement of the written question as a form of evaluation.Conclusions: in the Geography of Health subject subsist limitations in the relationship objective-contentevaluation, expressed in: continue orientation of the objective in the PEA, the determination of the contents essentials and the level they are imparted, the correspondence between imparted contents and the evaluations realized and the over measurement of the written question assimilation in the systemical evaluation. The design of actions in the methodological academic plan with these problematics be approached could be a way to contribute with the preparation of the academicians for a more efficient development of PEA.

This study solves the relevant problem of selecting an optimal switching and measurement circuit for the problems of reconstruction of the field of change in the conductivity in a biological object.Based on an analysis of publications in the area of const... see more

Thermocouples have been extensively used for the measurement of temperature since the advent of seebeck effect. Numerous sensors have been developed for temperature measurement, yet measurement of high temperature flowing fluid has been a challe... see more

One of cognitive abilities of students that should be trained and developed in the 21st century learning is high-level thinking skills. As higher order thinking skills are emerging trend in education, assessment instruments based on high order thinking sk... see more

The object of research is a model of the thermal state of a remote measurement device, determined by the operating conditions and caused by the need to confirm the operation of the device in ambient conditions according to the requirements of the specific... see more
