Smartphone data analysis for human activity recognition
2017
In recent years, the percentage of the population owning a smartphone has increased significantly. These devices provide the user with more and more functions, so that anyone is encouraged to carry one during the day, implicitly producing that can be analysed to infer knowledge of the userâs context. In this work we present a novel framework for Human Activity Recognition (HAR) using smartphone data captured by means of embedded triaxial accelerometer and gyroscope sensors. Some statistics over the captured sensor data are computed to model each activity, then real-time classification is performed by means of an efficient supervised learning technique. The system we propose also adopts a …
PENGARUH MODEL SNOWBALL THROWING TERHADAP HASIL BELAJAR SISWA KELAS V PADA MATA PELAJARAN PKn DI SD INPRES XX SOLOT
2020
ABSTRACTThis study aims to determine student learning outcomes by using the snowball throwing modelon PKn subjects in the diversity of ethnic groups in Indonesia towards the learning outcomes ofstudents in class V SD Inpres XX Solot Nita District, Sikka Regency. This research is aquantitative study with the tipe of experimental research method used in this study using thepre-experimental (nondesings) type one-group pretest-design method. The population andresearch sample were all students of class V which numbered 14 students. The test instrumentused to determine is in the form of a pre-test and post-test. Based on the learning outcomes thevalues obtained the average experimental class in t…
Positive and Negative Media Effects on University Students’ Learning: Preliminary Findings and a Research Program
2019
Research in communication science highlights positive as well as negative effects of news and social media on learning but focuses predominantly on the largely unintended knowledge acquisition of the overall population. Research in educational science deals with students’ knowledge acquisition but is largely limited to formal learning such as in university courses. In this paper, we report findings of a pilot study combining both approaches by dealing with mass and social media effects on university students’ learning. While this study reveals several effects, their influences and causality remain largely unclear. Therefore, we propose a research program to explain positive and negative med…
Diseño y validación de un cuestionario para conocer la opinión del alumnado de secundaria sobre la Música Festera y sus aplicaciones en el aula
2016
El objetivo del presente estudio es presentar el diseno y la validacion de un cuestionario para conocer la opinion del alumnado de ensenanza secundaria de Torrellano (Alicante) sobre la Musica Festera y sus posibilidades de aplicacion en el aula de secundaria. La poblacion de referencia esta formada por 597 alumnos de musica distribuidos en cuatro cursos de ensenanza secundaria (1o, 2o, 3o y 4o). Si trabajamos con un nivel de confianza del 95% y un margen de error del 5%, el tamano que precisa la muestra de los alumnos para ser representativa de la poblacion de referencia es de 234. El cuestionario fue enviado a toda la poblacion y la muestra generadora de datos resulto ser de 484. La prime…
Anomaly Detection in Dynamic Social Systems Using Weak Estimators
2009
Anomaly detection involves identifying observationsthat deviate from the normal behavior of a system. One ofthe ways to achieve this is by identifying the phenomena thatcharacterize “normal” observations. Subsequently, based on thecharacteristics of data learned from the “normal” observations,new observations are classified as being either “normal” or not.Most state-of-the-art approaches, especially those which belongto the family parameterized statistical schemes, work under theassumption that the underlying distributions of the observationsare stationary. That is, they assume that the distributions thatare learned during the training (or learning) phase, thoughunknown, are not time-varyin…
Context of validation of non-formal and informal learning in Spain: a comprehensive view
2019
The system of validation and accreditation of professional qualifications in Spain is offered as a certification opportunity, especially for vulnerable groups. The procedure is presented as an evaluative proposal that allows some inequalities associated with training and employment to be addressed. In this article we analyse whether this system really fosters social cohesion, considering the political situation that frames the procedure and the educational approach underlying it. The research methodology combines the documentary analysis and interviews with the application of the Delphi method. The most relevant results show that the socio-political context is favourable to competences accr…
MOOCEP: Un método para construir cursos masivos para Adultos Mayores: Usando una creación MOOCEP
2018
Hoy en día, la población de adultos mayores se ha incrementado significativamente en relación al total de la población mundial, así también este segmento en los últimos años ha mostrado una mayor adherencia e interés a los avances tecnológicos, entre ellos el Internet y sus servicios con la finalidad de desarrollar diferentes actividades tales como entretenimiento, información de actualidad, aprendizaje de diferentes tópicos, entre otros. Sin embargo, las aplicaciones y sitios web no tienen en cuenta los requisitos específicos de las personas de la tercera edad. De ahí, es necesario contar con metodologías, procesos y herramientas, las mismas que tengan en cuenta formas apropiadas de intera…
Arithmetic disabilities with and without reading difficulties: A comparison of arithmetic errors
1995
Arithmetic errors of 80 children with arithmetic disabilities, representing 3% of a population‐based sample, and of 80 sex‐ and age‐matched control children were systematically analyzed. In Analysis 1, covariance structure modeling (LISREL) was applied to analyze relations between reading, as measured by text reading accuracy and speed, and arithmetic error types. The results demonstrated that reading accuracy and speed were connected to errors in multiplication fact retrieval. In Analysis 2, a classification of children with arithmetic disabilities into subgroups by reading accuracy and speed difficulties revealed that children with dysfluent reading made more fact‐retrieval errors than di…
Learning Curve in Surgical Treatment of Odontoid Fixation for a Series of Type II C2 Fractures
2019
The craniovertebral junction (CVJ) is a complex anatomical area upon which most of the motion of the upper cervical spine depends [1]. Because of its unique range of motion, the CVJ is subject to several types of traumatic injury; it has been shown that odontoid fractures are the most common ones in the general population and are the most common isolated spinal fractures [2]. Accounting for up to 18% of all cervical fractures, odontoid fractures are the most common ones in elderly patients [3], in whom they account for up to 60% of spinal cord injuries [4].
