    Directory of Open Access Journals (Sweden)

    Alfonso Pérez Gama

    1993-07-01

    Full Text Available Ha llegado a su madurez la V Generación y con ello sus expresiones: la inteligencia artificial (1-2, los sistemas con el apoyo de conocimientos (3 y la ingeniería de software (4. En Colombia poca acogida parece tener. Es que los conocimientos constituyen un salto paradigmático hacia un nuevo orden mundial: el paso de la Sociedad de la Información a la Sociedad del Conocimiento. No es difícil de colegir la implicación de nuevas generaciones de sistemas de información y aunque la inmensa mayoría de gerentes no quieren saber de nuevos lenguajes ni reprogramaciones, aquí describiremos cómo es posible desarrollar e implementar un sistema inteligente de información gerencia. El concepto de "inteligente" se refiere a la viabilidad de tener un determinado grado de autonomía decisional, un evidente mejor desempeño, una capacidad real de adaptarse a las condiciones particulares de un usuario, el reconocer y generar un plan de trabajo al ejecutivo y en especial por el soporte a las decisiones, lo cual no significa la posibilidad de "reemplazar" al ejecutivo en esta labor, sino por el contrario constituirse en un sistema asistente del ejecutivo. Una innovación en esta arquitectura la constituye la tutoría experta en línea, que constituye un espacio para posibilitar el "entrenamiento gerencial" in situ y además la incorporación de técnicas de aprendizaje maquinal que funcionen en la práctica. Lo anterior significa que UN-SEEGSI pretende ser un ambiente de aprendizaje dual: donde se debe dar un aprendizaje vivencial por parte del usuario y donde debe aprender la máquina en forma subrepticia.

Durante el 2006, en los Estados Unidos los ingresos por videojuegos excedieron por primera vez en la historia a los del cine. Sin embargo, a pesar del auge en este mercado, todavía existen más ofertas de empleo que personas preparadas para ocuparlos. Para lograr el desarrollo de un videojuego se requiere de diversos conocimientos, como ser, diseño multimedial, manejo de lenguajes de programación especifica, uso de plataformas de actividades lúdicas, entre otros; sumado a estas actividades es necesario dotar al videojuego con un grado de inteligencia que lo haga no determinista; logrando que los jugadores mantengan durante una mayor cantidad de tiempo el interés por el mismo, pues de no ser así, los jugadores solo lo utilizarían hasta llegar hasta comprender la lógica de funcionamiento y perderian el interés por el videojuego. Es por esto que es de interés para la industria del video juego el desarrollo de motores basados en sistemas inteligentes tomando la experiencia adquirida en otros dominios, como ser, robótica, minería de datos y control de procesos, haciendo las adaptaciones necesarias al dominio en cuestión..

    Full Text Available El modelo LOPE es un sistema inteligente autónomo con aprendizaje basado en formación y ponderación de teorías. En los últimos años, se han elaborado varias modificaciones al modelo que han mejorado el rendimiento de su aprendizaje y de su planificación. Sin embargo, hay ciertos aspectos que aún no han sido abordados y cuyo diseño e implementación se cree incrementaría la convergencia de aprendizaje del modelo. Ellos son: (a el proceso de aprendizaje sólo se produce en la fase de observación, perdiendo la oportunidad de aprender a partir de la evaluación del resultado de los planes ejecutados, (b el índice utilizado para medir la calidad de los planes antes de ser ejecutados es un parámetro fijo, dejando abierta la posibilidad de que se ejecute una alta cantidad de planes condenados al fracaso. Este proyecto se propone desarrollar modificaciones o extensiones al modelo con el fin de mejorar estos aspectos e incrementar la curva de aprendizaje del sistema.

    (conventional or intelligent) is possible to get more power generation than if we use the automatic methods based on feedback MW control. Consequently, the financial benefit due to the MW generated along a period of 2 months, is equivalent to return the investment required if the CCPP would had been repowered. Test also showed that with the fuzzy based SGC is possible to get a 'little more' power generation than if we use the PID based SGC. The development and implementation of the SGC was made in three phases: First Phase: Upgrading of the simulation dynamic mathematical model and implementation in a new software platform based on LabWindows/CVI. Second Phase: Design, implementation and testing of the PID based SGC. Third Phase: Design and implementation and testing of the Intelligent SGC, based in fuzzy logic.

Thanks to these proposals the domotic market gently opens to one day become what we could call as the intelligent “home”. Thought out the last few years, huge technological improvements have provided the buildings with brand new senses. However ,the idea of a comfortable home where the coffee maker would notice our awakening or the entrance door would suggest it’s closure after we leave, is still far away. A new path is opening in front of us, one that won’t end until all the necessary steps will be taken in the same direction, the merging of interfaces in the field of domotics.There are many domotic tendencies and possibilities discussed in this article, many options for one very same goal, control.

    Full Text Available La Facultad de Ingeniería de la UNLP ofrece, como parte de las acciones destinadas a que sus futuros estudiantes cubran la brecha que los separa de la Universidad, un Curso de Nivelación a Distancia. Desde 2005, la propuesta se implementa a través del entorno virtual educativo WebUNLP de la UNLP, con el objetivo de ofrecer un curso de igual calidad que los cursos presenciales a quienes no pueden llegar a la Facultad mientras están cursando su último año en la escuela media. Implementar este curso, nos planteó sin dudas muchos desafíos, entre ellos las decisiones para la conformación de un sistema tutorial que llevaría a cabo la intervención docente. En el presente trabajo abordaremos en detalle: la composición de nuestro sistema tutorial, la definición de roles y funciones de cada tutor, la selección y capacitación de los mismos y los inconvenientes originados por no contar con un cargo docente para designar a los tutores. Incluiremos nuestro aporte acerca del perfil "docente-tutor a distancia" y la discusión de si todo buen docente de clases presenciales es un buen tutor para esta modalidad. Para finalizar, sintetizaremos la evaluación del sistema tutorial basada en la opinión de alumnos y tutores.

The fuzzy supervision system is integrated by three main modules: Supervision of blades temperature during the starting stage of the UTG; Supervision of blades temperature runback during the power generation stage of the UTG, and Control by Temperature during power generation stage of the UTG. The temperature fuzzy supervisor is implemented in a nonlinear mathematical model that simulates a CTCC. The obtained and analyzed results in the different sceneries of the simulation tests show that the temperature fuzzy supervision system displays a better performance than the obtained with the scheme of conventional supervision. [Spanish] En las Unidades Turbogas (UTG) de una Central Termoelectrica de Ciclo Combinado (CTCC), una de las variables criticas tanto desde el punto de vista operativo como desde el punto de vista de seguridad, es la temperatura de los alabes de la turbina.

Desde el punto de vista de seguridad se busca mantener la temperatura de los alabes en el limite impuesto por el fabricante, garantizando con esto la integridad de las partes internas de la UTG al evitar que esfuerzos termicos considerables decrementen su vida util. Para mantener la temperatura de alabes dentro del limite establecido, el sistema de control de la UTG cuenta con un sistema de supervision de temperatura de alabes, que modifica la referencia de los controladores PI de velocidad o de potencia generada, mismos que regulan la valvula de flujo de combustible a la camara de combustion de la UTG.

    This research is motivated by the belief in the importance of media in a learning process. Media as an intermediary serves to focus on the attention of learners. Selection of appropriate learning media is very influential on the success of the delivery of information itself both in terms of cognitive, affective and skills. Continental food is a course that studies food that comes from Europe and is very complex. To reduce verbalism and provide more real learning, then the tutorial media is needed. Media tutorials that are audio visual can provide a more concrete learning experience. The purpose of this research is to develop tutorial media in the form of video. The method used is the development method with the stages of analyzing the learning objectives, creating a story board, validating the story board, revising the story board and making video tutorial media. The results show that the making of storyboards should be very thorough, and detailed in accordance with the learning objectives to reduce errors in video capture so as to save time, cost and effort. In video capturing, lighting, shooting angles, and soundproofing make an excellent contribution to the quality of tutorial video produced. In shooting should focus more on tools, materials, and processing. Video tutorials should be interactive and two-way.

Short descriptions of three quite different types of current monitors are presented and a quantitative review of the classical transformer circuit is given. Recognizing that environmental noise pick-up may present a large source of error in quantitative measurements, signal handling considerations are given considerable attention using real-life examples. An example of a successful transport line beam current monitor implementation is presented and the tutorial concludes with a few comments about signal processing and current monitor calibration issues

    Full Text Available The purpose of the study is to examine the tutorial practices of in-service teachers to address the underachievement in the science education of K-12 students. Method: In-service teachers in Virginia and North Carolina were given a survey questionnaire to examine how they tutored students who were in need of additional instruction. Results: When these teachers were asked, “How do you describe a typical one-on-one science tutorial session?” the majority of their responses were categorized as teacher-directed. Many of the teachers would provide a science tutorial session for a student after school for 16-30 minutes, one to three times a week. Respondents also indicated they would rely on technology, peer tutoring, scientific inquiry, or themselves for one-on-one science instruction. Over half of the in-service teachers that responded to the questionnaire stated that they would never rely on outside assistance, such as a family member or an after school program to provide tutorial services in science. Additionally, very few reported that they incorporated the ethnicity, culture, or the native language of ELL students into their science tutoring sessions.

    Full Text Available La luz es un factor ambiental muy influyente en la calidad de vida y el rendimiento de las personas. Por esta razón es necesario crear e implementar tecnologías que ayuden a mantener ambientes sanos, en términos de iluminación, para los usuarios. Si a esto sumamos la gran cantidad de energía eléctrica que se desperdicia por malos hábitos de consumo y por el uso de dispositivos anticuados e ineficientes, resulta evidente la importancia del presente trabajo, el cual propone el diseño de una lámpara compacta y versátil que reemplace fácilmente a los focos tradicionales con ventajas como un control automático para el encendido y apagado en función del movimiento registrado en la habitación, un control automático de nivel de iluminación para mantener niveles óptimos en todo momento y regulación del tono de la luz de acuerdo a la habitación y a la hora del día. Para lograr lo anteriormente mencionado se utilizó tecnología LED, un microcontrolador y sensores que junto con técnicas de control gobiernan el comportamiento de la lámpara. Se establecieron varios parámetros de funcionamiento como nivel de iluminación y tono de la luz emitida los cuales se cumplieron dentro de ciertas condiciones operativas.

    2009-12-01

    Full Text Available La sociedad de Internet se construye sobre dos redes mundiales: una de computadores, clientes y servidores, la otra de personas, productoras y consumidoras de información. Se habla así de Internet como la Red de redes. Como se ve, Internet es entonces un tema que reviste intereses y problemas tanto tecnológicos como sociales. Pero aparte de esto, su desarrollo es irreversible, avasallante y masivo. Su influencia fue notable inicialmente en la academia y la ciencia, y en la primera década del siglo XXI, también lo es en los ámbitos cotidianos y económicos. Esta influencia determina conceptos nuevos frente a las comunicaciones y las distancias: pareciera que nada está lejos y que todo debe ser instantáneo. En la cotidianidad de las personas, aparecen unas costumbres y desaparecen otras; en el caso de las empresas, para su productividad y competitividad, se evidencian necesidades de cambios gerenciales que reconozcan el mundo digital.

    Li, Yuelin; Lord-Bessen, Jennifer; Shiyko, Mariya; Loeb, Rebecca

    2018-01-01

    This article is a how-to guide on Bayesian computation using Gibbs sampling, demonstrated in the context of Latent Class Analysis (LCA). It is written for students in quantitative psychology or related fields who have a working knowledge of Bayes Theorem and conditional probability and have experience in writing computer programs in the statistical language R . The overall goals are to provide an accessible and self-contained tutorial, along with a practical computation tool. We begin with how Bayesian computation is typically described in academic articles. Technical difficulties are addressed by a hypothetical, worked-out example. We show how Bayesian computation can be broken down into a series of simpler calculations, which can then be assembled together to complete a computationally more complex model. The details are described much more explicitly than what is typically available in elementary introductions to Bayesian modeling so that readers are not overwhelmed by the mathematics. Moreover, the provided computer program shows how Bayesian LCA can be implemented with relative ease. The computer program is then applied in a large, real-world data set and explained line-by-line. We outline the general steps in how to extend these considerations to other methodological applications. We conclude with suggestions for further readings.

    Science.gov (United States)

    Jeffery, Keven M; Maggio, Lauren; Blanchard, Mary

    2009-01-01

    Librarians at the Boston University Medical Center constructed two interactive online tutorials, "Introduction to EBM" and "Formulating a Clinical Question (PICO)," for a Family Medicine Clerkship and then quickly repurposed the existing tutorials to support an Evidence-based Dentistry course. Adobe's ColdFusion software was used to populate the tutorials with course-specific content based on the URL used to enter each tutorial, and a MySQL database was used to collect student input. Student responses were viewable immediately by course faculty on a password-protected Web site. The tutorials ensured that all students received the same baseline training and allowed librarians to tailor a subsequent library skills workshop to student tutorial answers. The tutorials were well-received by the medical and dental schools and have been added to mandatory first-year Evidence-based Medicine (EBM) and Evidence-based Dentistry (EBD) courses, meaning that every medical and dental student at BUMC will be expected to complete these tutorials.

    1991-09-01

    The importance of neural networks has grown dramatically during this decade. While only a few years ago they were primarily of academic interest, now dozens of companies and many universities are investigating the potential use of these systems and products are beginning to appear. The idea of building a machine whose architecture is inspired by that of the brain has roots which go far back in history. Nowadays, technological advances of computers and the availability of custom integrated circuits, permit simulations of hundreds or even thousands of neurons. In conjunction, the growing interest in learning machines, non-linear dynamics and parallel computation spurred renewed attention in artificial neural networks. Many tentative applications have been proposed, including decision systems (associative memories, classifiers, data compressors and optimizers), or parametric models for signal processing purposes (system identification, automatic control, noise canceling, etc.). While they do not always outperform standard methods, neural network approaches are already used in some real world applications for pattern recognition and signal processing tasks. The tutorial is divided into six lectures, that where presented at the Third Graduate Summer Course on Computational Physics (September 3-7, 1990) on Parallel Architectures and Applications, organized by the European Physical Society: (1) Introduction: machine learning and biological computation. (2) Adaptive artificial neurons (perceptron, ADALINE, sigmoid units, etc.): learning rules and implementations. (3) Neural network systems: architectures, learning algorithms. (4) Applications: pattern recognition, signal processing, etc. (5) Elements of learning theory: how to build networks which generalize.

oceanography. The GUT version 2.2 was released in April 2014 and beside some bug-fixes it adds the capability for the computation of Simple Bouguer Anomaly (Solid-Earth). During this fall a new GUT version 3 has been released. GUTv3 was further developed through a collaborative effort where the scientific communities participate aiming
on an implementation of remaining functionalities facilitating a wider span of research in the fields of Geodesy,
Oceanography and Solid earth studies.
Accordingly, the GUT version 3 has:
 - An attractive and easy to use Graphic User Interface (GUI) for the toolbox,
 - Enhance the toolbox with some further software functionalities such as to facilitate the use of gradients,
anisotropic diffusive filtering and computation of Bouguer and isostatic gravity anomalies.
 - An associated GUT VCM tool for analyzing the GOCE variance covariance matrices.

    Full Text Available Annette Burgess,1 Kim Oates,2 Kerry Goulston,2 Craig Mellis1 1Central Clinical School, Sydney Medical School, The University of Sydney, Sydney, NSW, Australia; 2Sydney Medical School, The University of Sydney, Sydney, NSW, Australia Background: Bedside teaching lies at the heart of medical education. The learning environment afforded to students during clinical tutorials contributes substantially to their knowledge, thinking, and learning. Situated cognition theory posits that the depth and breadth of the students' learning experience is dependent upon the attitude of the clinical teacher, the structure of the tutorial, and the understanding of tutorial and learning objectives. This theory provides a useful framework to conceptualize how students' experience within their clinical tutorials impacts their knowledge, thinking, and learning. Methods: The study was conducted with one cohort (n=301 of students who had completed year 1 of the medical program at Sydney Medical School in 2013. All students were asked to complete a three-part questionnaire regarding their perceptions of their clinical tutor's attributes, the consistency of the tutor, and the best features of the tutorials and need for improvement. Both quantitative and qualitative data were collected and analyzed using descriptive statistics. Results: The response rate to the questionnaire was 88% (265/301. Students perceived that their tutors displayed good communication skills and enthusiasm, encouraged their learning, and were empathetic toward patients. Fifty-two percent of students reported having the same communications tutor for the entire year, and 28% reported having the same physical examination tutor for the entire year. Students would like increased patient contact, greater structure within their tutorials, and greater alignment of teaching with the curriculum. Conclusion: Situated cognition theory provides a valuable lens to view students' experience of learning within the

    Full Text Available As cidades inteligentes são formas de apropriação do espaço urbano baseadas na utilização de três inteligências – a humana, a coletiva e a artificial – e que implica em transformações territoriais. A pesquisa objetiva discutir a cidade inteligente como uma reterritorialização do espaço das cidades, pelo exame conceitual de território, territorialidade, desterritorialização e reterritorialização. A justificativa está calcada na busca contemporânea por soluções aos problemas sociais, econômicos e culturais que as cidades enfrentam. A problemática nos induz a responder se as cidades inteligentes, ao criarem soluções, redefinem as formas e funções do espaço e por si constituem uma reterritorialização. A metodologia empregou a pesquisa documental e empírica, com revisão conceitual de autores meritórios nos temas como Komninos (2008, Haesbaert (2004, Raffestin (1993 e Sack (1986. A pesquisa apresenta as respostas à problemática de que o processo de desenvolvimento urbano propagado pelas cidades inteligentes é capaz de redefinir o uso e as ocupações dos espaços locais, regionais e nacionais, ensejando transformação territorial e, dessarte, uma reterritorialização. Abstract Smart cities are forms of appropriation of urban space based on the use of three intelligences – human, collective and artificial – and that implies territorial transformations. The research aims to discuss the smart city as a reterritorialization of all urban space through the conceptual examination of territory, territoriality, deterritorialization and reterritorialization. The justification is grounded in the contemporary search for solutions to social, economic and cultural problems facing cities. The problem leads us to respond if smart cities by creating solutions redefine the forms and space functions and by itself is a reterritorialization.

    Full Text Available O atual cenário observado nas fontes energéticas e hídricas do Brasil exige formas de uso mais controladas que garantam a sustentabilidade destes recursos. Nesse sentido, a proposta deste trabalho foi a de produzir resultados que possam ser rapidamente empregados pela sociedade de todas as classes sociais em um ambiente onde mais se concentra o consumo de água e energia: o box do banheiro. Foram desenvolvidas quatro estratégias que irão auxiliar o uso racional da água e energia. O primeiro consiste de uma intervenção sistêmica dos chuveiros domésticos visando reduzir o consumo de energia em até 75% além de reduzir a vazão de água, sem danificar a resistência elétrica. Uma segunda estratégia é o aperfeiçoamento de um trocador de calor para chuveiro que aproveita o calor da água rejeitada para o ralo para pré-aquecer a água que irá entrar no chuveiro, com aproveitamento de até 44%. Como terceira estratégia, uma camada de material hidrofóbica foi depositada sobre as paredes internas do box do chuveiro, visando diminuir a retenção de sujeiras e resíduos nestas superfícies, que resultou na redução da necessidade de lavar este ambiente e, por fim, uma quarta estratégia consiste de um sistema que monitora a atividade do banho por meio da resistividade da água descartada no ralo, esta resistividade irá indicar se a pessoa ainda está tomando banho ou se está havendo desperdício, caso seja caracterizado o desperdício uma solenoide irá cortar o fornecimento de água do chuveiro. Os resultados obtidos foram aderentes com o projetado e o trabalho sugere que novos estudos podem ser feitos visando melhorar a eficiência energética e hídrica no local de banho.

    Freitas, Ricardo Dantas Gadelha de [PETROBRAS S.A., Rio de Janeiro, RJ (Brazil)

    2003-07-01

    One of the most challenging tasks in an oil field is implementation of a software-based leak detection system on a multi-phase flow pipeline. This paper will discuss implementation of a leak detection system in a particular oil field using state-of-the-art signal processing techniques to apply to the data collected in a oil pipeline. This leak detection system is still in development and uses a more practical approach to the problem than traditional methods and was implemented on a PC under the Windows operating system. Windowing, joint time-frequency analysis and wavelets were considered to develop methods of detecting leaks by watching for the wavefront. The idea behind these techniques is to cut the signal of interest into several parts and then analyze the parts separately. It is impossible to know the exact frequency and the exact time of occurrence of the leak frequency in a signal. In other words, a leak signal can simply not be represented as a point in the time-frequency space. It is very important how one cuts the signal to implement the analysis. The wavelet transform or wavelet analysis is probably the most recent solution to overcome the shortcomings of the Fourier transform. So, this paper shows some tests and how these techniques are being implementing during the development of the system. (author)

What is the "magic" that is driving the popularity of the tutorial centre enterprise? Indeed, looking at the ongoing boom of tutorial centres in Hong Kong (there are almost 1,000 of them), it is difficult not to ask these questions. This paper examines the phenomenon of tutorial centres in Hong Kong and seeks to understand what draws students to these centres. Combining theories of marketing semiotics and emotion studies, the author investigates the pivotal role of media marketing in generating the "magic" of tutorial centres, whose advertising strategy includes, for example, a display of billboard posters featuring stylishly-dressed "celebrity teachers". The author reviews some of the literature available on the subject of tutorial centres. In a case study approach, he then maps out the pedagogy he observed in an English tutorial class, seeking heuristic insights into the kind of teaching students in the study were looking for. He argues that part of the "magical" attraction of what are essentially "cram schools" is their formulaic pedagogy of teaching and reinforcing exam skills. Finally, the paper considers the social implications of the tutorial centre industry in terms of media marketing of education and unequal access to tutorial services.

    2009-12-01

    We have written a software suite designed to facilitate solar data analysis by scientists, students, and the public, anticipating enormous datasets from future instruments. Our “STAR" suite includes an interactive learning section explaining 15 classes of solar events. Users learn software tools that exploit humans’ superior ability (over computers) to identify many events. Annotation tools include time slice generation to quantify loop oscillations, the interpolation of event shapes using natural cubic splines (for loops, sigmoids, and filaments) and closed cubic splines (for coronal holes). Learning these tools in an environment where examples are provided prepares new users to comfortably utilize annotation software with new data. Upon completion of our tutorial, users are presented with media of various solar events and asked to identify and annotate the images, to test their mastery of the system. Goals of the project include public input into the data analysis of very large datasets from future solar satellites, and increased public interest and knowledge about the Sun. In 2010, the Solar Dynamics Observatory (SDO) will be launched into orbit. SDO’s advancements in solar telescope technology will generate a terabyte per day of high-quality data, requiring innovation in data management. While major projects develop automated feature recognition software, so that computers can complete much of the initial event tagging and analysis, still, that software cannot annotate features such as sigmoids, coronal magnetic loops, coronal dimming, etc., due to large amounts of data concentrated in relatively small areas. Previously, solar physicists manually annotated these features, but with the imminent influx of data it is unrealistic to expect specialized researchers to examine every image that computers cannot fully process. A new approach is needed to efficiently process these data. Providing analysis tools and data access to students and the public have proven

  9. A TUTORIAL INTRODUCTION TO ADAPTIVE FRACTAL ANALYSIS

    Directory of Open Access Journals (Sweden)

    Michael A Riley

    2012-09-01

    Full Text Available The authors present a tutorial description of adaptive fractal analysis (AFA. AFA utilizes an adaptive detrending algorithm to extract globally smooth trend signals from the data and then analyzes the scaling of the residuals to the fit as a function of the time scale at which the fit is computed. The authors present applications to synthetic mathematical signals to verify the accuracy of AFA and demonstrate the basic steps of the analysis. The authors then present results from applying AFA to time series from a cognitive psychology experiment on repeated estimation of durations of time to illustrate some of the complexities of real-world data. AFA shows promise in dealing with many types of signals, but like any fractal analysis method there are special challenges and considerations to take into account, such as determining the presence of linear scaling regions.

    Dalege, Jonas; Borsboom, Denny; van Harreveld, Frenk; van der Maas, Han L J

    2017-07-01

    In this article, we provide a brief tutorial on the estimation, analysis, and simulation on attitude networks using the programming language R. We first discuss what a network is and subsequently show how one can estimate a regularized network on typical attitude data. For this, we use open-access data on the attitudes toward Barack Obama during the 2012 American presidential election. Second, we show how one can calculate standard network measures such as community structure, centrality, and connectivity on this estimated attitude network. Third, we show how one can simulate from an estimated attitude network to derive predictions from attitude networks. By this, we highlight that network theory provides a framework for both testing and developing formalized hypotheses on attitudes and related core social psychological constructs.

    Leardi, Riccardo

    2009-10-12

    In this tutorial the main concepts and applications of experimental design in chemistry will be explained. Unfortunately, nowadays experimental design is not as known and applied as it should be, and many papers can be found in which the "optimization" of a procedure is performed one variable at a time. Goal of this paper is to show the real advantages in terms of reduced experimental effort and of increased quality of information that can be obtained if this approach is followed. To do that, three real examples will be shown. Rather than on the mathematical aspects, this paper will focus on the mental attitude required by experimental design. The readers being interested to deepen their knowledge of the mathematical and algorithmical part can find very good books and tutorials in the references [G.E.P. Box, W.G. Hunter, J.S.

    Full Text Available Resumen: Uno de los objetivos más importantes de los Sistemas Inteligentes de Transporte (ITS es evitar la pérdida de precisión en el posicionamiento y guiado del vehículo, debido a la disminución en la calidad de la señal del Sistema de Posicionamiento Global (GPS. En este artículo, se presenta un sistema de posicionamiento formado por la combinación de un GPS con una unidad de medida inercial ayudada por los sensores embarcados en el coche para realizar el guiado. En función de la precisión proporcionada por el GPS, el sistema discrimina entre tres posibles comportamientos: 1 Si la precisión es centimétrica, el GPS se encarga en solitario del guiado. 2 Si no se recibe la señal GPS, el control lo toma la unidad inercial. 3 Si la precisión de la señal del GPS no es centimétrica, la posición del vehículo se calcula mediante una combinación de ambas medidas. El sistema se ha instalado en un Citroën C3 Pluriel. Los resultados muestran un correcto comportamiento del vehículo en diferentes situaciones y prueban la necesidad de integrar la información sensorial para realizar un control de navegación óptimo.

    2014-06-01

    This longitudinal study reports the results of a replication of Tutorials in Introductory Physics in high schools of a Latin-American country. The main objective of this study was to examine the suitability of Tutorials for local science education reform. Conceptual learning of simple resistive electric circuits was determined by the application of the single-response multiple-choice test "Determining and Interpreting Resistive Electric Circuits Concepts Test" (DIRECT) to high school classes taught with Tutorials and traditional instruction. The study included state and privately run schools of different socioeconomic profiles, without formal laboratory space and equipment, in classes of mixed-gender and female-only students, taught by novice and experienced instructors. Results systematically show that student learning is significantly higher in the Tutorials classes compared with traditional teaching for all of the studied conditions. The results also show that long-term learning (one year after instruction) in the Tutorials classes is highly satisfactory, very similar to the performance of the samples of college students used to develop the test DIRECT. On the contrary, students following traditional instruction returned one year after instruction to the poor performance (students attending seven universities in Spain and four Latin-American countries. Some replication and adaptation problems and difficulties of this experience are noted, as well as recommendations for successful use of Tutorials in high schools of similar educational systems.

    A medical imaging informatics infrastructure (MIII) platform is an organized method of selecting tools and synthesizing data from HIS/RIS/PACS/ePR systems with the aim of developing an imaging-based diagnosis or treatment system. Evaluation and analysis of these systems can be made more efficient by designing and implementing imaging informatics simulators. This tutorial introduces the MIII platform and provides the definition of treatment/diagnosis systems, while primarily focusing on the development of the related simulators. A medical imaging informatics (MII) simulator in this context is defined as a system integration of many selected imaging and data components from the MIII platform and clinical treatment protocols, which can be used to simulate patient workflow and data flow starting from diagnostic procedures to the completion of treatment. In these processes, DICOM and HL-7 standards, IHE workflow profiles, and Web-based tools are emphasized. From the information collected in the database of a specific simulator, evidence-based medicine can be hypothesized to choose and integrate optimal clinical decision support components. Other relevant, selected clinical resources in addition to data and tools from the HIS/RIS/PACS and ePRs platform may also be tailored to develop the simulator. These resources can include image content indexing, 3D rendering with visualization, data grid and cloud computing, computer-aided diagnosis (CAD) methods, specialized image-assisted surgical, and radiation therapy technologies. Five simulators will be discussed in this tutorial. The PACS-ePR simulator with image distribution is the cradle of the other simulators. It supplies the necessary PACS-based ingredients and data security for the development of four other simulators: the data grid simulator for molecular imaging, CAD-PACS, radiation therapy simulator, and image-assisted surgery simulator.

Using combinations of different types of sample introduction systems and ionization methods, several novel techniques have been developed over the last few years with many applications (e.g., food safety screening; detection of pharmaceuticals and drug abuse; monitoring of environmental pollutants; detection of explosives for antiterrorism and forensics; characterization of biological compounds for proteomics and metabolomics; molecular imaging analysis; and monitoring chemical and biochemical reactions). Electrospray ionization and atmospheric pressure chemical ionization are the two main ionization principles most commonly used in ambient ionization mass spectrometry. This tutorial paper provides a review of the publications related to ambient ionization techniques. We describe and compare the underlying principles of operation, ionization processes, detecting mass ranges, sensitivity, and representative applications of these techniques.

    Full Text Available As in other developing nations, important concerns surrounding education in Indonesia involve two issues: quantity versus quality. Quality concerns have now been somewhat addressed by the establishment of the Indonesian Open Learning University (Universitas Terbuka in 1984. The concern for quality, however, has not yet been completely resolved. Learning support, believed to be key for achieving good quality distance education, has been limited. This paper presents the results of two pilot projects that examined tutorials provided via Internet and Fax-Internet technologies. It is a report that also shows that the Universitas Terbuka is faced with both visible and invisible challenges. Visible challenges include limitations in the availability of technology infrastructure and issues of inadequate access, while invisible challenges include the readiness of Indonesian people to adopt and take advantage of new technology for educational purposes. Despite the results of the pilot project, it is suggested that Universitas Terbuka should continue to utilize Internet and Fax-Internet as two of its communication channels with students.

  10. Low temperature plasma biomedicine: A tutorial review

    2014-01-01

    Gas discharge plasmas formed at atmospheric pressure and near room temperature have recently been shown to be potentially useful for surface and wound sterilization, antisepsis, bleeding cessation, wound healing, and cancer treatment, among other biomedical applications. This tutorial review summarizes the field, stressing the likely role of reactive oxygen and nitrogen species created in these plasmas as the biologically and therapeutically active agents. Reactive species, including radicals and non-radical compounds, are generated naturally within the body and are now understood to be essential for normal biological functions. These species are known to be active agents in existing therapies for wound healing, infection control, and cancer treatment. But they are also observed at elevated levels in persons with many diseases and are associated with aging. The physical and chemical complexity of plasma medical devices and their associated biochemical effects makes the development of safe, effective plasma medical devices and procedures a challenge, but encouragingly rapid progress has been reported around the world in the last several years

    Highlights: → Ambient ionization technique allows the direct analysis of sample surfaces with little or no sample pretreatment. → We sort ambient ionization techniques into three main analytical strategies, direct ionization, direct desorption/ionization, and two-step ionization. → The underlying principles of operation, ionization processes, detecting mass ranges, sensitivity, and representative applications of these techniques are described and compared. - Abstract: Ambient ionization is a set of mass spectrometric ionization techniques performed under ambient conditions that allows the direct analysis of sample surfaces with little or no sample pretreatment. Using combinations of different types of sample introduction systems and ionization methods, several novel techniques have been developed over the last few years with many applications (e.g., food safety screening; detection of pharmaceuticals and drug abuse; monitoring of environmental pollutants; detection of explosives for antiterrorism and forensics; characterization of biological compounds for proteomics and metabolomics; molecular imaging analysis; and monitoring chemical and biochemical reactions). Electrospray ionization and atmospheric pressure chemical ionization are the two main ionization principles most commonly used in ambient ionization mass spectrometry. This tutorial paper provides a review of the publications related to ambient ionization techniques. We describe and compare the underlying principles of operation, ionization processes, detecting mass ranges, sensitivity, and representative applications of these techniques.

    The terahertz range possesses significant untapped potential for applications including high-volume wireless communications, noninvasive medical imaging, sensing, and safe security screening. However, due to the unique characteristics and constraints of terahertz waves, the vast majority of these applications are entirely dependent upon the availability of beam control techniques. Thus, the development of advanced terahertz-range beam control techniques yields a range of useful and unparalleled applications. This article provides an overview and tutorial on terahertz beam control. The underlying principles of wavefront engineering include array antenna theory and diffraction optics, which are drawn from the neighboring microwave and optical regimes, respectively. As both principles are applicable across the electromagnetic spectrum, they are reconciled in this overview. This provides a useful foundation for investigations into beam control in the terahertz range, which lies between microwaves and infrared light. Thereafter, noteworthy experimental demonstrations of beam control in the terahertz range are discussed, and these include geometric optics, phased array devices, leaky-wave antennas, reflectarrays, and transmitarrays. These techniques are compared and contrasted for their suitability in applications of terahertz waves.

  14. Iterative Decoding of Concatenated Codes: A Tutorial

    2005-05-01

    Full Text Available The turbo decoding algorithm of a decade ago constituted a milestone in error-correction coding for digital communications, and has inspired extensions to generalized receiver topologies, including turbo equalization, turbo synchronization, and turbo CDMA, among others. Despite an accrued understanding of iterative decoding over the years, the “turbo principle” remains elusive to master analytically, thereby inciting interest from researchers outside the communications domain. In this spirit, we develop a tutorial presentation of iterative decoding for parallel and serial concatenated codes, in terms hopefully accessible to a broader audience. We motivate iterative decoding as a computationally tractable attempt to approach maximum-likelihood decoding, and characterize fixed points in terms of a “consensus” property between constituent decoders. We review how the decoding algorithm for both parallel and serial concatenated codes coincides with an alternating projection algorithm, which allows one to identify conditions under which the algorithm indeed converges to a maximum-likelihood solution, in terms of particular likelihood functions factoring into the product of their marginals. The presentation emphasizes a common framework applicable to both parallel and serial concatenated codes.

    Full Text Available La Web 2.0 propone nuevos desafíos para asegurar la “Accesibilidad Universal.” Los diferentes tipos de usuarios Web se enfrentan con numerosas barreras de accesibilidad cuando interactúan con los diferentes tipos de sitios y aplicaciones que coexisten hoy en la Web 2.0, desde los denominados Simple Web Presence hasta las Rich Internet Applications o las Mobile Web Applications. En este escenario, la Accesibilidad Web es un atributo de calidad clave para propiciar el acceso a la información y a los servicios Web y proveer beneficios en el desarrollo de productos para la Web tales como la optimización de motores de búsqueda y la escalabilidad de aplicaciones multi-dispositivo. Los enfoques que asisten a la evaluación de la Accesibilidad de productos Web existentes, son semi-automáticos y requieren de la intervención humana en la detección de “falsos positivos”/“falsos negativos” y en la corrección de errores comprobados automática y manualmente. Para simplificar el proceso de toma de decisiones y reducir la intervención humana, las herramientas de evaluación, reparación, transformación y filtrado incorporan técnicas de automatización basadas en conceptos de inteligencia artificial. En este trabajo, se presentan y describen los enfoques y/o herramientas basados en agentes inteligentes y luego se propone una comparativa para analizar las contribuciones que estos hacen a la mejora de la accesibilidad, ya sea aplicando técnicas propias o las Web Content Accessibility Guidelines propuestas por el consorcio W3C.

  1. Tutorial: Asteroseismic Data Analysis with DIAMONDS

    Science.gov (United States)

    Corsaro, Enrico

    Since the advent of the space-based photometric missions such as CoRoT and NASA's Kepler, asteroseismology has acquired a central role in our understanding about stellar physics. The Kepler spacecraft, especially, is still releasing excellent photometric observations that contain a large amount of information not yet investigated. For exploiting the full potential of these data, sophisticated and robust analysis tools are now essential, so that further constraining of stellar structure and evolutionary models can be obtained. In addition, extracting detailed asteroseismic properties for many stars can yield new insights on their correlations to fundamental stellar properties and dynamics. After a brief introduction to the Bayesian notion of probability, I describe the code Diamonds for Bayesian parameter estimation and model comparison by means of the nested sampling Monte Carlo (NSMC) algorithm. NSMC constitutes an efficient and powerful method, in replacement to standard Markov chain Monte Carlo, very suitable for high-dimensional and multimodal problems that are typical of detailed asteroseismic analyses, such as the fitting and mode identification of individual oscillation modes in stars (known as peak-bagging). Diamonds is able to provide robust results for statistical inferences involving tens of individual oscillation modes, while at the same time preserving a considerable computational efficiency for identifying the solution. In the tutorial, I will present the fitting of the stellar background signal and the peak-bagging analysis of the oscillation modes in a red-giant star, providing an example to use Bayesian evidence for assessing the peak significance of the fitted oscillation peaks.

  2. Analysis of information security reliability: A tutorial

    International Nuclear Information System (INIS)

    Kondakci, Suleyman

    2015-01-01

    This article presents a concise reliability analysis of network security abstracted from stochastic modeling, reliability, and queuing theories. Network security analysis is composed of threats, their impacts, and recovery of the failed systems. A unique framework with a collection of the key reliability models is presented here to guide the determination of the system reliability based on the strength of malicious acts and performance of the recovery processes. A unique model, called Attack-obstacle model, is also proposed here for analyzing systems with immunity growth features. Most computer science curricula do not contain courses in reliability modeling applicable to different areas of computer engineering. Hence, the topic of reliability analysis is often too diffuse to most computer engineers and researchers dealing with network security. This work is thus aimed at shedding some light on this issue, which can be useful in identifying models, their assumptions and practical parameters for estimating the reliability of threatened systems and for assessing the performance of recovery facilities. It can also be useful for the classification of processes and states regarding the reliability of information systems. Systems with stochastic behaviors undergoing queue operations and random state transitions can also benefit from the approaches presented here. - Highlights: • A concise survey and tutorial in model-based reliability analysis applicable to information security. • A framework of key modeling approaches for assessing reliability of networked systems. • The framework facilitates quantitative risk assessment tasks guided by stochastic modeling and queuing theory. • Evaluation of approaches and models for modeling threats, failures, impacts, and recovery analysis of information systems

    For the 2016 tutorial, NCAR/CGD requested a total budget of $70,000 split equally between DOE and NSF. The funds were used to support student participation (travel, lodging, per diem, etc.). Lectures and practical session support was primarily provided by local participants at no additional cost (see list below). The seventh annual Community Earth System Model (CESM) tutorial (2016) for students and early career scientists was held 8 – 12 August 2016. As has been the case over the last few years, this event was extremely successful and there was greater demand than could be met. There was continued interest in support of the NSF’s EaSM Infrastructure awards, to train these awardees in the application of the CESM. Based on suggestions from previous tutorial participants, the 2016 tutorial experience again provided direct connection to Yellowstone for each individual participant (rather than pairs), and used the NCAR Mesa Library. The 2016 tutorial included lectures on simulating the climate system and practical sessions on running CESM, modifying components, and analyzing data. These were targeted to the graduate student level. In addition, specific talks (“Application” talks) were introduced this year to provide participants with some in-depth knowledge of some specific aspects of CESM.

  4. A tutorial on the principles of harmonic intonation for trombonists

    Keener, Michael Kenneth

    A Tutorial on the Principles of Harmonic Intonation for Trombonists includes a manual containing background information, explanations of the principles of harmonic intonation, and printed musical examples for use in learning and practicing the concepts of harmonic intonation. An audio compact disk containing music files corresponding to the printed music completes the set. This tutorial is designed to allow performing musicians and students to practice intonation skills with the pitch-controlled music on the compact disc. The music on the CD was recorded in movable-comma just intonation, replicating performance parameters of wind, string, and vocal ensembles. The compact disc includes sixty tracks of ear-training exercises and interval studies with which to practice intonation perception and adjustment. Tuning notes and examples of equal-tempered intervals and just intervals are included on the CD. The intonation exercises consist of musical major scales, duets, trios, and quartet phrases to be referenced while playing the printed music. The CD tracks allow the performer to play scales in unison (or practice other harmonic intervals) or the missing part of the corresponding duet, trio, or quartet exercise. Instructions in the manual guide the user through a process that can help prepare musicians for more accurate musical ensemble performance. The contextual essay that accompanies the tutorial includes a description of the tutorial, a review of related literature, methodology of construction of the tutorial, evaluations and outcomes, conclusions and recommendations for further research, and a selected bibliography.

    Full Text Available This longitudinal study reports the results of a replication of Tutorials in Introductory Physics in high schools of a Latin-American country. The main objective of this study was to examine the suitability of Tutorials for local science education reform. Conceptual learning of simple resistive electric circuits was determined by the application of the single-response multiple-choice test “Determining and Interpreting Resistive Electric Circuits Concepts Test” (DIRECT to high school classes taught with Tutorials and traditional instruction. The study included state and privately run schools of different socioeconomic profiles, without formal laboratory space and equipment, in classes of mixed-gender and female-only students, taught by novice and experienced instructors. Results systematically show that student learning is significantly higher in the Tutorials classes compared with traditional teaching for all of the studied conditions. The results also show that long-term learning (one year after instruction in the Tutorials classes is highly satisfactory, very similar to the performance of the samples of college students used to develop the test DIRECT. On the contrary, students following traditional instruction returned one year after instruction to the poor performance (<20% shown before instruction, a result compatible with the very low level of conceptual knowledge of basic physics recently determined by a systematic study of first-year students attending seven universities in Spain and four Latin-American countries. Some replication and adaptation problems and difficulties of this experience are noted, as well as recommendations for successful use of Tutorials in high schools of similar educational systems.

    Full Text Available El embarazo en la adolescencia representa un problema social de grandes proporciones en el mundo actual y en consecuencia también en Ecuador. Hoy en día, este tema ha sido objeto de estudio por numerosos investigadores y docentes de la enseñanza básica superior a escala mundial. Este artículo surge de una investigación llevada a cabo en la Unidad Educativa ITSUP, Ecuador, donde se registró el comportamiento de la problemática en el proceso educativo de la sexualidad y tiene como objetivo proponer un programa como un sistema integral de prevención del embarazo en adolescentes, que contribuya a la reducción del embarazo precoz. Se aplicó un diagnóstico, con diferentes actividades que incluyen entrevistas a docentes y padres de familia, un análisis observacional a los diferentes espacios de desarrollo de los estudiantes. En el programa se enfatiza la tutoría como vía para connotar los derechos humanos, equidad de género y práctica de valores. La concepción del programa sienta las bases para una educación sexual en los adolescentes, donde la acción tutorial juega un rol importante para dar respuesta a las necesidades de los alumnos en educación sexual y prevención de embarazos, contribuyéndose a la reducción de la aparición precoz de estos. Palabras clave: Paternidad responsable, adolescentes, práctica de valores, educación sexual, resiliencia.

    Full Text Available Nowadays, in order to perform the optimal installations automatic control, buildings structure incorporates a new kind of computers which are different from the desk computers dedicated to user’s personal tasks.These computers spread in the form of a network that is overlapped with the building structure in such a way that soon we shall speak about the computer omnipresence in the building.The building control system is considered in this paper as an intelligent agent. This means a control system provided with sensors and actuators to interact with its environment. This control system must develop its activity in order to get autonomously the programmed goals. A generic control building architecture is presented as a step towards the systematic development of control building systems.A project for the development of a software tool is also presented. This tool intends to support and make easy the programming of such kind of control systems. This project is been developed in the Department of Photonic Technology at Universidad Politécnica of Madrid.La necesidad de realizar un control automático óptimo de las instalaciones de un edificio ha provocado que un nuevo tipo de ordenadores, diferentes de los ordenadores de sobremesa que utilizan personalmente los habitantes del edificio, entren a formar parte de la arquitectura del propio edificio.Estos ordenadores se van extendiendo en forma de una red imbricada con la propia estructura del edificio de tal manera que pronto podremos hablar de la omnipresencia del ordenador en el edificio.En este trabajo se plantea el sistema de control del edificio como un agente inteligente, como un sistema que dotado de sensores para percibir su entorno, y de medios de actuación para modificarlo, realiza permanentemente ciertas operaciones de procesamiento de información y acciones sobre el propio edificio persiguiendo de manera autónoma alcanzar los objetivos para los que ha sido diseñado.Como un paso

    Although numerical models that researchers use to analyze large astronomy data sets may be easily found on NASA websites, tutorials on how to use these models and understanding the products of the models are lacking. Thus, communication with the public is ineffective. Where the public could easily engage with data and models to determine if their work and lives could be impacted, and if so, to plan accordingly, a lack of good tutorials typically results in the public waiting for a tweet, a post on Facebook, an announcement on a NASA webpage, an alert sent via text message or email, etc. An example is a solar flare or coronal mass ejection event that may impact GPS devices, the precision of which is heavily relied upon by several sectors of the public and military. To allow the public to engage in real time with solar data and NASA developed heliophysics software, we have developed tutorials. In this work, we present our tutorials made for NASA's Living With a Star Program on the such as Integrated Space Weather Analysis (ISWA) layout and the WSA-ENLIL-CONE Model to analyze a CME Evolution that occurred in 2010. We present our results and our analysis of the public's ability to understand the model's predictions of whether the event will impact Earth. By training the public to use the data and to understand model predictions, we turn passive recipients into engaged and self-supporting users of NASA data of space weather events.

  13. Tutorial Video Series: Using Stakeholder Outreach to Increase ...

    Science.gov (United States)

    The limited amount of toxicity data on thousands of chemicals found in consumer products has led to the development of research endeavors such as the U.S. EPA’s Toxicity Forecaster (ToxCast). ToxCast uses high-throughput screening technology to evaluate thousands of chemicals for potential toxicity. At the end of 2013, U.S. EPA released ToxCast chemical data on almost 2,000 chemicals through the interactive Chemical Safety for Sustainability (iCSS) Dashboard. The iCSS Dashboard provides public access to the high-throughput screening data that can be used to inform the evaluation of the safety of chemicals. U.S. EPA recognized early in the development of ToxCast that stakeholder outreach was needed in order to translate the complex scientific information featured in the iCSS Dashboard and data, with the goal of educating the diverse user community through targeted efforts to increase data usage and analysis. Through survey feedback and the request of stakeholders, a series of tutorial videos to demonstrate how to access and use the data has been planned, and the first video of the series has been released to guide data usage. This presentation will describe the video tutorial strategy including an overview of: 1) Stakeholder outreach goals and approach; 2) Planning, production, and dissemination of tutorial videos; 3) Overview of Survey Feedback; 4) Overview of tutorial video usage statistics and usage of the ToxCast data.

    Elder, Ruth L; Lewis, Peter A; Windsor, Carol A; Wheeler, Margaret; Forster, Elizabeth; Foster, Joanne; Chapman, Helen

    2011-09-01

    Chronic nursing shortages have placed increasing pressure on many nursing schools to recruit greater numbers of students with the consequence of larger class sizes. Larger class sizes have the potential to lead to student disengagement. This paper describes a case study that examined the strategies used by a group of nursing lecturers to engage students and to overcome passivity in a Bachelor of Nursing programme. A non-participant observer attended 20 tutorials to observe five academics deliver four tutorials each. Academics were interviewed both individually and as a group following the completion of all tutorial observations. All observations, field notes, interviews and focus groups were coded separately and major themes identified. From this analysis two broad categories emerged: getting students involved; and engagement as a struggle. Academics used a wide variety of techniques to interest and involve students. Additionally, academics desired an equal relationship with students. They believed that both they and the students had some power to influence the dynamics of tutorials and that neither party had ultimate power. The findings of this study serve to re-emphasise past literature which suggests that to engage students, the academics must also engage. Copyright © 2011 Elsevier Ltd. All rights reserved.

    2003-01-01

    The aim of this project is to develop an interactive tutorial designed for medical students training in radiation protection in order to use its definitive version in a collaborative group of medical schools. The contents of the tutorial matchers the outlines proposed by the EC guidelines on education and training in Radiation Protection for Medical exposures (RP118), for medical and dental schools. The tutorial is organised in virtual lectures, following a similar structure than the traditional lectures, slides and explanations. There is a central script for each theme with a forward-return interaction. Additionally, branches with deeper explanations (drawings, images, videos,...) are provided to the user. The tutorial is being developed on a set of power Point presentations, linked between them. The user can choose two ways sto launch each lecture, based either on spoken (audio) or written explanations. We present the initial version of a useful tool for pre-graduate training of general practitioners in Radiation Protection, which is a complementary tool for personally adapted computed-based education. Most of the contents can be easily adapted for other students of health related careers (i. e. nurses, technologists...) The use of multimedia tools has been recommended in the field of radiation protection, but developing these tools is time consuming and needs expertise in both, educative and multimedia resources. This projects takes part of more than a dozen multimedia projects on different radiology related subjects developed in our department. (Author) 6 refs

    Full Text Available The research and writing processes are often hidden mysteries to our students. A key point in the online tutorial Search and Write (Søk and Skriv has been to supply our students with tools to handle these processes. Learning cases embedded in the tutorial allow us to demonstrate a variety of working techniques and to better cater for a diverse student population. The tutorial can be used as an independent resource for students and as a teaching aid for both library sessions on information literacy and for faculty-led sessions on academic writing. Our tutorial is available in Norwegian and in English and thereby the tutorial can be used with both local and international students. An online tutorial is aimed at all students and therefore the information literacy content is of a general kind. The pedagogical foundation for the Search and Write tutorial is in contextual learning. Adding context to our general content has been important to us and we decided to develop learning cases for this purpose. In our online tutorial we have developed three sample student blogs, Kuhlthau’s information search process functions as a template in structuring the students’ stories. The blogs are learning cases, developed with the intent of illustrating various aspects of academic writing tasks. The blog stories are idealized and touch upon many of the known stumbling stones for student writers. Contextualising the search and write process like this let us explore the diversity of student assignments and from various fields of study. When our real-life students use Search and Write they may use their own research question as a point of departure. They can read the blog stories and relate these stories to their own experiences. They can use the How to brainstorm-tips provided in Sofie’s blog. Christian’s use of tutors, library staff and his writing group can provide guidance on who to ask for help.

    Full Text Available The benefits of solving problems have been widely acknowledged by literature. Its implementation in e–learning platforms can make easier its management and the learning process itself. However, its implementation can also become a very time–consuming task, particularly when the number of problems to generate is high. In this tutorial we describe a methodology that we have developed aiming to alleviate the workload of producing a great deal of problems in Moodle for an undergraduate business course. This methodology follows a six-step process and allows evaluating student’s skills in problem solving, minimizes plagiarism behaviors and provides immediate feedback. We expect this tutorial encourage other educators to apply our six steps process, thus benefiting themselves and their students of its advantages.

    In 2004 the Faculty of Medicine of Universidad de La Frontera in Chile implemented curricular changes, incorporating small group problem based learning in different carriers. To explore aspects that hamper or facilitate tutorial problem based learning from the perspective of tutors. Six in depth interviews and a focus group with tutors were carried out in 2010 and 2011. Data were analyzed through constant comparisons using the program ATLAS ti, guaranteeing credibility, reliance, validation and transferability. Five hundred and twenty eight (528) significance units were identified and 25 descriptive categories emerged. The categories of tutor motivation, methodological domain, tutor responsibility, tutor critical capacity, disciplinary domain, student participation and tutor-student interaction were emphasized. Three qualitative domains were generated, namely tutor skills, transformation of student roles and institutional commitment. Tutorial teaching is favored by teachers when the institutions train them in the subject, when there is administrative support and an adequate infrastructure and coordination.

    This tutorial will introduce Fortran developers to unit-testing and test-driven development (TDD) using pFUnit. As with other unit-testing frameworks, pFUnit, simplifies the process of writing, collecting, and executing tests while providing clear diagnostic messages for failing tests. pFUnit specifically targets the development of scientific-technical software written in Fortran and includes customized features such as: assertions for multi-dimensional arrays, distributed (MPI) and thread-based (OpenMP) parallellism, and flexible parameterized tests.These sessions will include numerous examples and hands-on exercises that gradually build in complexity. Attendees are expected to have working knowledge of F90, but familiarity with object-oriented syntax in F2003 and MPI will be of benefit for the more advanced examples. By the end of the tutorial the audience should feel comfortable in applying pFUnit within their own development environment.

    Recent advances in photon counting detection technology have led to significant research interest in X-ray imaging. As a tutorial level review, this paper covers a wide range of aspects related to X-ray photon counting detector characterization. The tutorial begins with a detailed description of the working principle and operating modes of a pixelated X-ray photon counting detector with basic architecture and detection mechanism. Currently available methods and techniques for charactering major aspects including energy response, noise floor, energy resolution, count rate performance (detector efficiency), and charge sharing effect of photon counting detectors are comprehensively reviewed. Other characterization aspects such as point spread function (PSF), line spread function (LSF), contrast transfer function (CTF), modulation transfer function (MTF), noise power spectrum (NPS), detective quantum efficiency (DQE), bias voltage, radiation damage, and polarization effect are also remarked. A cadmium telluride (CdTe) pixelated photon counting detector is employed for part of the characterization demonstration and the results are presented. This review can serve as a tutorial for X-ray imaging researchers and investigators to understand, operate, characterize, and optimize photon counting detectors for a variety of applications.

    Avetyan, Smbat

    The Physics Education Research (PER) group at the University of Washington have researched traditional teaching methods and found that students in introductory physics are lacking a conceptual understanding of the physics material. The solution they put forth is an interactive tutorial program designed to meet the lack of conceptual understanding. Since the tutorial programs inception at CSU Los Angeles in Fall 2006 no evaluation has been successfully undertaken therefore the effect of the tutorial program in the physics 200 series is deeply obscure to the department. The research has shed light on the tutorial program and brought into context its effectiveness on the overall physics 200 series courses at CSU Los Angeles. The researcher has addressed the following research questions, what overall effect does the tutorial program have on the Physics 200 series curriculum? What is the size and significance of gains attributable to the undergraduate calculus based Physics 200 series tutorial program at CSU Los Angeles? What can we learn from gains about individual weekly lessons from the Physics 200 series tutorial courses? What is the correlation of tutorial gains with student final course grades? Are the gains from the tutorial program different for genders? Is there a difference in gains based on the different students' colleges?

    Apesar das pesquisas com sistemas silvipastoris terem sido iniciadas no final da década de 1970, as informações geradas até hoje não são em grande número. As vantagens advindas de um sistema silvipastoril são inúmeras e devidamente reconhecidas. Pelo fato de ser uma técnica de uso da terra capaz de recuperar ecossistemas alterados pelo mau manejo, estes sistemas, pela integração de atividades agrícolas, pecuárias e silviculturais, passam a representar uma tecnologia que confere maior sustentabilidade que os sistemas tradicionais, nos quais os monocultivos são predominantes. Nos últimos anos, instituições de ensino, pesquisa e extensão do País têm se voltado para o desenvolvimento de tais sistemas. O governo de Minas Gerais, por meio de sua Secretaria de Estado de Agricultura e de órgãos vinculados, vem promovendo a condução de modelos agrossilvipastoris num processo integrado de ocupação do solo, denominado lavoura-pecuária-silvicultura. Apesar dos grandes avanços no conhecimento de culturas anuais e dos componentes arbóreos, principalmente o eucalipto, e de gramíneas forrageiras tolerantes à diminuição da intensidade luminosa, ainda é necessário se comnhecer melhor o manejo do sub-bosque sob os efeitos do pastejo.

  16. Tutorial for Wave Equation Inversion of Skeletonized Data

    KAUST Repository

    Lu, Kai

    2017-04-25

    Full waveform inversion of seismic data is often plagued by cycle skipping problems so that an iterative optimization method often gets stuck in a local minimum. To avoid this problem we simplify the objective function so that the iterative solution can quickly converge to a solution in the vicinity of the global minimum. The objective function is simplified by only using parsimonious and important portions of the data, which are defined as skeletonized data. We now present a mostly non-mathematical tutorial that explains the theory of skeletonized inversion. We also show its effectiveness with examples.

    International Nuclear Information System (INIS)

    Vega, J. M.; Pena, J. J.; Rossell, M. A.; Calvo, J. L.

    2003-01-01

    Every day, the number of didactic materials presented through Internet, is greater. However, we have not effective tools to obtain the potential academic yield of such a media. The complexity of the Internet protocols, in spite of the easy handling, makes it almost impossible. In this work, a didactic tool to analyse graphically the navigation through a tutorial on radiation protection is presented. For its visualisation, some subjects related with the biogical effects of radiation and with radiological quantities and units have been selected. The graphical representation shows the tour travelled by the user, in our case students of Medicine, and the time employed in eyeing each one of the nodes. The answers to problems about the contents of each node and its graphical representation in the navigation map allow us to follow the learning progress of the students as well as their standard of navigation. The graphical representation analysis of multiple users permits to detect some of the mistakes in the design of the tutorial and to suggest to the author a method for amending these mistakes. The system is developed on LINEX, but it is easily adaptable to other operating systems. (Author) 7 refs

  2. Redesigning nursing tutorials for ESL students: a pilot study.

    Science.gov (United States)

    San Miguel, Caroline; Townsend, Lisa; Waters, Cheryl

    2013-04-01

    Increased enrolments of Bachelor of Nursing (BN) students who speak English as a second language (ESL) can help create a multilingual and culturally diverse workforce that is better prepared to meet the needs of increasingly diverse health populations. However, although ESL enrolments are increasing, attrition rates for ESL students tend to be higher than those of native speakers of English, partly due to academic failure. At the same time, concerns have been expressed in some quarters about the low levels of English language of entering students. As it is unlikely that language entry levels to university will be raised, sustainable programmes that help ESL students better meet the academic challenges they may face need to be developed. So far, models of ESL support have been mostly an adjunct to their degree, voluntary and not well attended. This paper discusses a model using tutorials integrated into the first year nursing curriculum that were specifically designed for ESL students with low levels of English language proficiency. The paper also examines students' perceptions of such tutorials, which they found beneficial to their learning.

    2017-12-01

    Full Text Available Conducting undergraduate studies in the English language, while only a small minority of students speak English at home, poses many problems to learning in the South African context. This article explores how restrictive language policies may influence proper learning and impact negatively on the self-understanding of students. It also explores how multilingualism could help to reduce the continued reliance on English, without doing away with English in its entirety. This is especially relevant in light of English and other colonial languages still being perceived as “languages of power” (Stroud & Kerfoot, 2013, p. 403. Therefore, attention is given to the link between language and power, especially in light of languages often being used to implement, display and preserve power. Language use in the classroom, especially with regard to codeswitching (also called translanguaging, is discussed. Finally, it explores the success that was achieved during multilingual tutorial sessions. In the tutorials, students were encouraged to explore the course work in their native languages, thereby internalising it and getting a better understanding thereof.

  4. Guidelines for Effective TAP (Translation for Academic Purposes Tutorial Courses

    Directory of Open Access Journals (Sweden)

    Elham Yazdanmehr

    2014-03-01

    Full Text Available An increasing need is felt by the university students, especially at Master’s or PhD level, to get a satisfactory command of English so as to manage great amounts of technical materials and articles published internationally. Public and private language institutions, however, have not responded to this need properly specially in non-English speaking countries including Iran. Therefore, the only way left for the students is to demand tutorial sessions which are rare, and if existing, of diverse questionable quality. There seems to be a dearth of base-line or criteria released in any form to define and guide the tutors’ approach and techniques which can be in accordance with university students’ needs and purposes. Aiming to fill this gap, the present paper attempts to be a pioneering research in the realm of TAP (Translation for Academic Purposes tutorial courses and intends to provide guidelines on text selection, role allocation, timing, rate, assignments and other relevant issues in this area. The guidelines are provided based on a post facto case study carried out by one of the authors which created the motive for this research and may further clarify the significance of the issues discussed. The recommended guidelines consist of 5 basic elements and 3 principles. It was discovered, and is expected for others as well, that following these guidelines helps to manage a TAP course in the best and most fruitful way with the least time wasted and with satisfactory result.

    In our questionnaire, a video tutorial illustrating the management of shoulder dystocia was considered by health personnel as a useful complementary training tool. We prepared a 5-min video tutorial on the management of shoulder dystocia, using a simulator that includes maternal pelvic and baby models. We performed a survey among obstetric personnel in order to assess their opinion on the tutorial by inviting them to watch the video tutorial and answer an online questionnaire. Five multiple-choice questions were set, focusing on the video's main objectives: clarity, simplicity and usefulness.

    , and robust production management systems. In this paper we propose a holonic system for scheduling and control of flexible manufacturing systems. The system is based on a new architecture that integrates two decision levels: a level of auction-based scheduling, where each holon performs its own local schedule, and another level of dispatching and control that coordinate holons activities. Unlike other studies in which local schedules are integrated into a global schedule that centralizes the system, the proposed system is not so. The dispatching and control mechanism is responsible to integrate the local programs. In addition, the developed prototype can operate with different degrees of decentralization, which allows evaluating the advantages that our approach provides by means of simulation.

  13. A Tutorial on Parallel and Concurrent Programming in Haskell

    Science.gov (United States)

    Peyton Jones, Simon; Singh, Satnam

    This practical tutorial introduces the features available in Haskell for writing parallel and concurrent programs. We first describe how to write semi-explicit parallel programs by using annotations to express opportunities for parallelism and to help control the granularity of parallelism for effective execution on modern operating systems and processors. We then describe the mechanisms provided by Haskell for writing explicitly parallel programs with a focus on the use of software transactional memory to help share information between threads. Finally, we show how nested data parallelism can be used to write deterministically parallel programs which allows programmers to use rich data types in data parallel programs which are automatically transformed into flat data parallel versions for efficient execution on multi-core processors.

  14. Tutorial: Parallel Computing of Simulation Models for Risk Analysis.

    Reilly, Allison C; Staid, Andrea; Gao, Michael; Guikema, Seth D

    2016-10-01

    Simulation models are widely used in risk analysis to study the effects of uncertainties on outcomes of interest in complex problems. Often, these models are computationally complex and time consuming to run. This latter point may be at odds with time-sensitive evaluations or may limit the number of parameters that are considered. In this article, we give an introductory tutorial focused on parallelizing simulation code to better leverage modern computing hardware, enabling risk analysts to better utilize simulation-based methods for quantifying uncertainty in practice. This article is aimed primarily at risk analysts who use simulation methods but do not yet utilize parallelization to decrease the computational burden of these models. The discussion is focused on conceptual aspects of embarrassingly parallel computer code and software considerations. Two complementary examples are shown using the languages MATLAB and R. A brief discussion of hardware considerations is located in the Appendix. © 2016 Society for Risk Analysis.

    Pereira, Francisco; Mitchell, Tom; Botvinick, Matthew

    2009-03-01

    Interpreting brain image experiments requires analysis of complex, multivariate data. In recent years, one analysis approach that has grown in popularity is the use of machine learning algorithms to train classifiers to decode stimuli, mental states, behaviours and other variables of interest from fMRI data and thereby show the data contain information about them. In this tutorial overview we review some of the key choices faced in using this approach as well as how to derive statistically significant results, illustrating each point from a case study. Furthermore, we show how, in addition to answering the question of 'is there information about a variable of interest' (pattern discrimination), classifiers can be used to tackle other classes of question, namely 'where is the information' (pattern localization) and 'how is that information encoded' (pattern characterization).

    Science.gov (United States)

    Worden, Keith; Staszewski, Wieslaw J.; Hensman, James J.

    2011-01-01

    A great many computational algorithms developed over the past half-century have been motivated or suggested by biological systems or processes, the most well-known being the artificial neural networks. These algorithms are commonly grouped together under the terms soft or natural computing. A property shared by most natural computing algorithms is that they allow exploration of, or learning from, data. This property has proved extremely valuable in the solution of many diverse problems in science and engineering. The current paper is intended as a tutorial overview of the basic theory of some of the most common methods of natural computing as they are applied in the context of mechanical systems research. The application of some of the main algorithms is illustrated using case studies. The paper also attempts to give some indication as to which of the algorithms emerging now from the machine learning community are likely to be important for mechanical systems research in the future.

    Science.gov (United States)

    He, Ji-Huan

    2014-11-01

    This tutorial review of fractal-Cantorian spacetime and fractional calculus begins with Leibniz's notation for derivative without limits which can be generalized to discontinuous media like fractal derivative and q-derivative of quantum calculus. Fractal spacetime is used to elucidate some basic properties of fractal which is the foundation of fractional calculus, and El Naschie's mass-energy equation for the dark energy. The variational iteration method is used to introduce the definition of fractional derivatives. Fractal derivative is explained geometrically and q-derivative is motivated by quantum mechanics. Some effective analytical approaches to fractional differential equations, e.g., the variational iteration method, the homotopy perturbation method, the exp-function method, the fractional complex transform, and Yang-Laplace transform, are outlined and the main solution processes are given.

To distinguish between these two accounts, Miller (1982) derived the well-known race model inequality, which has become a routine test for behavioral data in experiments...... with redundant signals. In this tutorial, we review the basic properties of redundant signals experiments and current statistical procedures used to test the race model inequality during the period between 2011 and 2014. We highlight and discuss several issues concerning study design and the test of the race...... model inequality, such as inappropriate control of Type I error, insufficient statistical power, wrong treatment of omitted responses or anticipations and the interpretation of violations of the race model inequality. We make detailed recommendations on the design of redundant signals experiments...

  1. Multi-objective optimization using genetic algorithms: A tutorial

    International Nuclear Information System (INIS)

    Konak, Abdullah; Coit, David W.; Smith, Alice E.

    2006-01-01

    Multi-objective formulations are realistic models for many complex engineering optimization problems. In many real-life problems, objectives under consideration conflict with each other, and optimizing a particular solution with respect to a single objective can result in unacceptable results with respect to the other objectives. A reasonable solution to a multi-objective problem is to investigate a set of solutions, each of which satisfies the objectives at an acceptable level without being dominated by any other solution. In this paper, an overview and tutorial is presented describing genetic algorithms (GA) developed specifically for problems with multiple objectives. They differ primarily from traditional GA by using specialized fitness functions and introducing methods to promote solution diversity

  3. Tutorial on Using Regression Models with Count Outcomes Using R

    Directory of Open Access Journals (Sweden)

    A. Alexander Beaujean

    2016-02-01

    Full Text Available Education researchers often study count variables, such as times a student reached a goal, discipline referrals, and absences. Most researchers that study these variables use typical regression methods (i.e., ordinary least-squares either with or without transforming the count variables. In either case, using typical regression for count data can produce parameter estimates that are biased, thus diminishing any inferences made from such data. As count-variable regression models are seldom taught in training programs, we present a tutorial to help educational researchers use such methods in their own research. We demonstrate analyzing and interpreting count data using Poisson, negative binomial, zero-inflated Poisson, and zero-inflated negative binomial regression models. The count regression methods are introduced through an example using the number of times students skipped class. The data for this example are freely available and the R syntax used run the example analyses are included in the Appendix.

  6. Partial Least Squares tutorial for analyzing neuroimaging data

    Directory of Open Access Journals (Sweden)

    Patricia Van Roon

    2014-09-01

    Full Text Available Partial least squares (PLS has become a respected and meaningful soft modeling analysis technique that can be applied to very large datasets where the number of factors or variables is greater than the number of observations. Current biometric studies (e.g., eye movements, EKG, body movements, EEG are often of this nature. PLS eliminates the multiple linear regression issues of over-fitting data by finding a few underlying or latent variables (factors that account for most of the variation in the data. In real-world applications, where linear models do not always apply, PLS can model the non-linear relationship well. This tutorial introduces two PLS methods, PLS Correlation (PLSC and PLS Regression (PLSR and their applications in data analysis which are illustrated with neuroimaging examples. Both methods provide straightforward and comprehensible techniques for determining and modeling relationships between two multivariate data blocks by finding latent variables that best describes the relationships. In the examples, the PLSC will analyze the relationship between neuroimaging data such as Event-Related Potential (ERP amplitude averages from different locations on the scalp with their corresponding behavioural data. Using the same data, the PLSR will be used to model the relationship between neuroimaging and behavioural data. This model will be able to predict future behaviour solely from available neuroimaging data. To find latent variables, Singular Value Decomposition (SVD for PLSC and Non-linear Iterative PArtial Least Squares (NIPALS for PLSR are implemented in this tutorial. SVD decomposes the large data block into three manageable matrices containing a diagonal set of singular values, as well as left and right singular vectors. For PLSR, NIPALS algorithms are used because it provides amore precise estimation of the latent variables. Mathematica notebooks are provided for each PLS method with clearly labeled sections and subsections. The

    2018-04-23

    When estimating the average effect of a binary treatment (or exposure) on an outcome, methods that incorporate propensity scores, the G-formula, or targeted maximum likelihood estimation (TMLE) are preferred over naïve regression approaches, which are biased under misspecification of a parametric outcome model. In contrast propensity score methods require the correct specification of an exposure model. Double-robust methods only require correct specification of either the outcome or the exposure model. Targeted maximum likelihood estimation is a semiparametric double-robust method that improves the chances of correct model specification by allowing for flexible estimation using (nonparametric) machine-learning methods. It therefore requires weaker assumptions than its competitors. We provide a step-by-step guided implementation of TMLE and illustrate it in a realistic scenario based on cancer epidemiology where assumptions about correct model specification and positivity (ie, when a study participant had 0 probability of receiving the treatment) are nearly violated. This article provides a concise and reproducible educational introduction to TMLE for a binary outcome and exposure. The reader should gain sufficient understanding of TMLE from this introductory tutorial to be able to apply the method in practice. Extensive R-code is provided in easy-to-read boxes throughout the article for replicability. Stata users will find a testing implementation of TMLE and additional material in the Appendix S1 and at the following GitHub repository: https://github.com/migariane/SIM-TMLE-tutorial. © 2018 The Authors.

    2006-12-01

    Purpose - To assess an innovative tutoring program named 'Student-Led Objective Tutorial' (SLOT) among undergraduate medical students. Method - The program was conceptualized by the Pharmacology Unit of Faculty of Medicine and Health Sciences, Asian Institute of Medicine Science & Technology (AIMST), Malaysia and implemented in the middle of 2005. A cohort of 246 medical undergraduate students (spread across 5 consecutive batches) participated. Following a brief explanation on the purpose and nature of SLOT, each batch was divided into small groups and was given a reading assignment on 4 previously delivered lecture topics. Each group was asked to prepare 3-5 multiple choice questions (MCQs) of their own in PowerPoint format to be presented, in turns, to the whole class on the day of SLOT. The proceedings were facilitated by 2 lecturers. Student feedback on the efficacy and benefits were assessed through an anonymous self administered questionnaire. Results - About 76% (188) of the students favored SLOT. The acceptance rate of SLOT was higher among males. There was no significant difference between batches in their opinions on whether to pursue SLOT in future. The most prevalent positive comment was that SLOT enhanced learning skills, and the negative comment being, it consumed more time. Conclusions - SLOT is a novel tutorial method which can offset faculty shortage with advantages like enhanced interest among teachers and learners, uniform reach of content, opportunities for group learning, and involvement of visual aids as teaching-learning (T-L) method. SLOT unraveled the students' potential of peer tutoring both inside as well as outside the classroom. Consumer tutors (students) can be tapped as a resource for SLOT for all subjects and courses in healthcare teaching.

    Renal function can be measured noninvasively with radionuclides in a extremely safe way compared to other diagnosis techniques. Nevertheless, due to the fact that radioactive materials are used in this procedure, it is necessary to maximize its benefits, therefore all efforts are justifiable in the development of data analysis support tools for this diagnosis modality. The objective of this work is to develop a prototype for a system model based on Artificial Intelligence devices able to perform functions related to cintilographic image analysis of the urinary system. Rules used by medical experts in the analysis of images obtained with {sup 99m} Tc+DTPA and /or {sup 99m} Tc+DMSA were modeled and a Neural Network diagnosis technique was implemented. Special attention was given for designing programs user-interface. Human Factor Engineering techniques were taking in account allowing friendliness and robustness. The image segmentation adopts a model based on Ideal ROIs, which represent the normal anatomic concept for urinary system organs. Results obtained using Artificial Neural Networks for qualitative image analysis and knowledge model constructed show the feasibility of Artificial Neural Networks for qualitative image analysis and knowledge model constructed show feasibility of Artificial Intelligence implementation that uses inherent abilities of each technique in the medical diagnosis image analysis.

    2016-07-01

    The aim of this audit was to determine the effectiveness of large group tutorials for teaching neurology to medical students. Students were asked to complete a questionnaire rating their confidence on a ten point Likert scale in a number of domains in the undergraduate education guidelines from the Association of British Neurologists (ABN). We then arranged a series of interactive large group tutorials for the class and repeated the questionnaire one month after teaching. In the three core domains of neurological: history taking, examination and differential diagnosis, none of the students rated their confidence as nine or ten out of ten prior to teaching. This increased to 6% for history taking, 12 % in examination and 25% for differential diagnosis after eight weeks of tutorials. This audit demonstrates that in our centre, large group tutorials were an effective means of teaching, as measured by the ABN guidelines in undergraduate neurology.

    Tissue, Brian M.; Earp, Ronald L.; Yip, Ching-Wan; Anderson, Mark R.

    1996-05-01

    This progress report describes the development and student use of World-Wide-Web-based prelaboratory exercises in senior-level Instrumental Analysis during the 1995 Fall semester. The laboratory preparation exercises contained hypermedia tutorials and multiple-choice questions that were intended to familiarize the students with the experiments and instrumentation before their laboratory session. The overall goal of our work is to explore ways in which computer and network technology can be applied in education to improve the cost-effectiveness and efficacy of teaching. The course material can be accessed at http://www.chem.vt.edu/chem-ed/4114/Fall1995.html. The students were instructed to read their experimental procedure and to do the relevant laboratory preparation exercise. The individual tutorial documents were primarily text that provided basic theoretical and experimental descriptions of analytical and instrumental methods. The documents included hyperlinks to basic concepts, simple schematics, and color graphics of experimental set-ups or instrumentation. We chose the World-Wide Web (WWW) as the delivery platform for this project because of the ease of developing, distributing, and modifying hypermedia material in a client-server system. The disadvantage of the WWW is that network bandwidth limits the size and sophistication of the hypermedia material. To minimize internet transfer time, the individual documents were kept short and usually contained no more than 3 or 4 inline images. After reading the tutorial the students answered several multiple-choice questions. The figure shows one example of a multiple-choice question and the response page. Clicking on the "Submit answer" button calls a *.cgi file, which contains instructions in the PERL interpretive language, that generates the response page and saves the date, time, and student's answer to a file on the server. Usage and student perception of the on-line material was evaluated from server logs and

    This paper describes the pilot evaluation of an Internet-based intervention, designed to teach counselors and problem gamblers about how electronic gambling machines (EGMs) work. This study evaluated the tutorial using assessment tools, such as rating scales and test of knowledge about EGMs and random chance. The study results are based on a number of samples, including problem gambling counselors ( n  = 25) and problem gamblers ( n  = 26). The interactive tutorial was positively rated by both clients and counselors. In addition, we found a significant improvement in scores on a content test about EGM games for both clients and counselors. An analysis of the specific items suggests that the effects of the tutorial were mainly on those items that were most directly related to the content of the tutorial and did not always generalize to other items. This tutorial is available for use with clients and for education counselors. The data also suggest that the tutorial is equally effective in group settings and in individual settings. These results are promising and illustrate that the tool can be used to teach counselors and clients about game design. Furthermore, research is needed to evaluate its impact on gambling behavior.

    Explicit emphasis on teaching science process skills leads to both gains in the skills themselves and, strikingly, deeper understanding of content. Here, we created and tested a series of online, interactive tutorials with the goal of helping undergraduate students develop science process skills. We designed the tutorials in accordance with evidence-based multimedia design principles and student feedback from usability testing. We then tested the efficacy of the tutorials in an introductory undergraduate biology class. On the basis of a multivariate ordinary least-squares regression model, students who received the tutorials are predicted to score 0.82 points higher on a 15-point science process skill assessment than their peers who received traditional textbook instruction on the same topic. This moderate but significant impact indicates that well-designed online tutorials can be more effective than traditional ways of teaching science process skills to undergraduate students. We also found trends that suggest the tutorials are especially effective for nonnative English-speaking students. However, due to a limited sample size, we were unable to confirm that these trends occurred due to more than just variation in the student group sampled.

  3. Online Pedagogical Tutorial Tactics Optimization Using Genetic-Based Reinforcement Learning.

    Tutorial tactics are policies for an Intelligent Tutoring System (ITS) to decide the next action when there are multiple actions available. Recent research has demonstrated that when the learning contents were controlled so as to be the same, different tutorial tactics would make difference in students' learning gains. However, the Reinforcement Learning (RL) techniques that were used in previous studies to induce tutorial tactics are insufficient when encountering large problems and hence were used in offline manners. Therefore, we introduced a Genetic-Based Reinforcement Learning (GBML) approach to induce tutorial tactics in an online-learning manner without basing on any preexisting dataset. The introduced method can learn a set of rules from the environment in a manner similar to RL. It includes a genetic-based optimizer for rule discovery task by generating new rules from the old ones. This increases the scalability of a RL learner for larger problems. The results support our hypothesis about the capability of the GBML method to induce tutorial tactics. This suggests that the GBML method should be favorable in developing real-world ITS applications in the domain of tutorial tactics induction.

    Full Text Available This study assessed student perceptions about an online information literacy tutorial, CORE (Comprehensive Online Research Education, to plan for the next generation of tutorials. The CORE tutorial includes seven modules: “Planning Your Project,” “Topic Exploration,” “Types of Information,” “Search Tools,” “Search Strategies,” “Evaluating Sources,” and “Copyright, Plagiarism, and Citing Sources.” First-year students in biology and nursing courses responded to a survey after they completed the CORE modules. The students liked learning through an online tutorial. They thought that the tutorial could be improved with shorter modules and the addition of video and audio content. Few students reported learning important information from the “Copyright, Plagiarism, and Citing Sources,” “Evaluating Resources,” and “Types of Information” modules. They suggested topics for additional tutorials: how to use library databases and Microsoft Excel; how to evaluate the quality of information, how to cite references in a bibliography, and how to find statistics.

    Full Text Available Os autores chamam a atenção sôbre os erros de diagnóstico nos casos de neuroblastomicose, seja nas formas meningoencefálicas, seja nas tumorais. São focalizadas a paracoccidioidose e a criptococose. Depois de caracterizarem clìnicamente a paracoccidioidose, acentuam a raridade das formas nervosas (1,2% dos casos dessa micose autopsiados no Departamento de Anatomia Patológica da Faculdade de Medicina da Universidade de São Paulo. Pela revisão da literatura foi verificado haver apenas 12 casos registrados. 0 caso de Casiello e Klass é o único em que o diagnóstico foi feito em vida; os demais, ou constituem achado de necropsia, ou foram inesperadamente revelados pelo exame histopatológico realizado após intervenções cirúrgicas. Os autores registram 2 casos de paracoccidioidose do sistema nervoso. No primeiro, tratava-se de meningomielorra-diculite crônica, sendo o parasito identificado no escarro; o segundo era portador de síndrome de compressão medular, cuja patogenia é discutida pelos autores, tendo sido a etiologia paracoccidióidica comprovada pelo exame da polpa e biópsia ganglionares. Considerações clínicas sôbre a criptococose precedem o relato de um caso de meningoencefalomielite subaguda, no qual fôra feito em vida o diagnóstico de paracoccidioidose, pelo exame micológico do liqüido cefalorraqueano; êste paciente, embora medicado com doses maciças de sulfa e tiossemicarbarsona, veio a falecer, tendo o exame anátomo-patológico revelado tratar-se, na realidade, de lesões nervosas produzidas pelo Crypíococcus neo-formans. Nos três casos era incisivo o caráter neurocirúrgico da sintomatologia. Entretanto, ante o diagnóstico de paracoccidioidose, foi instituído tratamento pelas sulfas, vacina específica e tiossemicarbarsona. Os resultados foram excelentes no caso 2, em que a terapêutica pôde ser instituída mais precocemente; melhoras também foram obtidas no caso 1. No caso 3, foram verificadas

    Full Text Available As micoses do sistema nervoso central não têm merecido atenção cuidadosa dos neurologistas. Elas afetam o neuraxe em diferente percentagem: a granulomatose criptocóccica (torulose é a mais freqüente, seguindo-se a actinomicose; a granulomatose paracoccidióidica só excepcionalmente determina lesões meningoencefálicas. Do ponto de vista clínico, as neuromicoses podem ser divididas em duas formas: tumorais encefalomedulares e meningíticas. Estas predominam sobre as tumorais, das quais são mais freqüentes as de localização encefálica. Não são raros os quadros mistos, meningoencetálicos. As formas tumorals encefálicas abrangem vários tipos anátomo-patológicos - abscesso, granuloma, nódulos e cistos - sendo mais comuns os dois primeiros, todos êles produzindo o quadro clinico da síndrome hipertensiva intracraniana. As formas meningomedulares, em geral, são secundárias às lesões ósseas vertebrais, sendo a actinomicose, por ser a mais osteófila, a micose que mais freqüentemente atinge a medula. Nestes casos, o quadro clínico da síndrome compressiva é o mais comum. As meninges participam do processo fúngico, na maior parte dos casos; as manifestações clínicas variam desde o simples meningismo, até as meningites purulentas e meningoencefalites graves, havendo a possibilidade de se formarem aracnoidites císticas, ependimites e bloqueios ventriculares, do aqueduto ou mesmo do canal raquidiano. O diagnóstico das micoses do sistema nervoso central é comumente um "achado de autópsia". Somente a verificação do cogumelo no líquor e o seu isolamento permitem um diagnóstico seguro. Outros dados liquóricos, quando bem interpretados com os achados clínicos e neurológicos, orientam o analista na pesquisa do agente fúngico. O quadro anátomo-patológico nada tem de caraterístico, a não ser a presença do agente parasitário e só o seu encontro firma o diagnóstico. Examinamos 25 casos de granulomatose

    2005-01-01

    A variety of examples have arisen in which the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) has been used for applications beyond bibliographic metadata interchange. One of these examples is the use of OAI-PMH to harvest resources and not just metadata. Advanced resource discovery and preservations capabilities are possible by combining complex object formats such as MPEG-21 DIDL, METS and SCORM with the OAI-PMH. In this tutorial, we review community conventions and practices that have provided the impetus for resource harvesting. We show how the introduction of complex object formats for the representation of resources leads to a robust, OAI-PMH-based framework for resource harvesting. We detail how complex object formats fit in the OAI-PMH data model, and how (compound) digital objects can be represented using a complex object format for exposure by an OAI-PMH repository. We also cover tools that are available for the implementation of an OAI-PMH-based resource harvesting solution. Fu...

    Highlights: •The concepts of warping and alignment are introduced. •The most important warping methods are critically reviewed and explained. •Reference selection, evaluation and place of warping in preprocessing are discussed. •Some pitfalls, especially for LC–MS and similar data, are addressed. •Examples are provided, together with programming scripts to rework and extend them. -- Abstract: Warping methods are an important class of methods that can correct for misalignments in (a.o.) chemical measurements. Their use in preprocessing of chromatographic, spectroscopic and spectrometric data has grown rapidly over the last decade. This tutorial review aims to give a critical introduction to the most important warping methods, the place of warping in preprocessing and current views on the related matters of reference selection, optimization, and evaluation. Some pitfalls in warping, notably for liquid chromatography–mass spectrometry (LC–MS) data and similar, will be discussed. Examples will be given of the application of a number of freely available warping methods to a nuclear magnetic resonance (NMR) spectroscopic dataset and a chromatographic dataset. As part of the Supporting Information, we provide a number of programming scripts in Matlab and R, allowing the reader to work the extended examples in detail and to reproduce the figures in this paper.

    2014-11-01

    As healthcare costs climb around the world, public and private payers alike are demanding evidence of a treatment's value to support approval and reimbursement decisions. Health economics and outcomes research, or HEOR, offers tools to answer questions about a treatment's value, as well as its real-world effects and cost-effectiveness. Given that nutrition interventions have to compete for space in budgets along with biopharmaceutical products and devices, nutrition is now increasingly coming to be evaluated through HEOR. This tutorial introduces the discipline of HEOR and motivates its relevance for nutrition. We first define HEOR and explain its role and relevance in relation to randomized controlled trials. Common HEOR study types--including burden of illness, effectiveness studies, cost-effectiveness analysis, and valuation studies--are presented, with applications to nutrition. Tips for critically reading HEOR studies are provided, along with suggestions on how to use HEOR to improve patient care. Directions for future research are discussed. © 2014 Abbott Nutrition.

  15. Tutorial: Determination of thermal boundary resistance by molecular dynamics simulations

    Liang, Zhi; Hu, Ming

    2018-05-01

    Due to the high surface-to-volume ratio of nanostructured components in microelectronics and other advanced devices, the thermal resistance at material interfaces can strongly affect the overall thermal behavior in these devices. Therefore, the thermal boundary resistance, R, must be taken into account in the thermal analysis of nanoscale structures and devices. This article is a tutorial on the determination of R and the analysis of interfacial thermal transport via molecular dynamics (MD) simulations. In addition to reviewing the commonly used equilibrium and non-equilibrium MD models for the determination of R, we also discuss several MD simulation methods which can be used to understand interfacial thermal transport behavior. To illustrate how these MD models work for various interfaces, we will show several examples of MD simulation results on thermal transport across solid-solid, solid-liquid, and solid-gas interfaces. The advantages and drawbacks of a few other MD models such as approach-to-equilibrium MD and first-principles MD are also discussed.

    2015-06-01

    Given the growing prominence of computational modeling in the acquisition research community, we present a tutorial on how to use computational modeling to investigate learning strategies that underlie the acquisition process. This is useful for understanding both typical and atypical linguistic development. We provide a general overview of why modeling can be a particularly informative tool and some general considerations when creating a computational acquisition model. We then review a concrete example of a computational acquisition model for complex structural knowledge referred to as syntactic islands. This includes an overview of syntactic islands knowledge, a precise definition of the acquisition task being modeled, the modeling results, and how to meaningfully interpret those results in a way that is relevant for questions about knowledge representation and the learning process. Computational modeling is a powerful tool that can be used to understand linguistic development. The general approach presented here can be used to investigate any acquisition task and any learning strategy, provided both are precisely defined.

    In this tutorial review, we discuss the defect chemistry of selected amphoteric oxide semiconductors in conjunction with their significant impact on the development of renewable and sustainable solid state energy conversion devices. The effect of electronic defect disorders in semiconductors appears to control the overall performance of several solid-state ionic devices that include oxide ion conducting solid oxide fuel cells (O-SOFCs), proton conducting solid oxide fuel cells (H-SOFCs), batteries, solar cells, and chemical (gas) sensors. Thus, the present study aims to assess the advances made in typical n- and p-type metal oxide semiconductors with respect to their use in ionic devices. The present paper briefly outlines the key challenges in the development of n- and p-type materials for various applications and also tries to present the state-of-the-art of defect disorders in technologically related semiconductors such as TiO(2), and perovskite-like and fluorite-type structure metal oxides.

    Microsimulation models are becoming increasingly common in the field of decision modeling for health. Because microsimulation models are computationally more demanding than traditional Markov cohort models, the use of computer programming languages in their development has become more common. R is a programming language that has gained recognition within the field of decision modeling. It has the capacity to perform microsimulation models more efficiently than software commonly used for decision modeling, incorporate statistical analyses within decision models, and produce more transparent models and reproducible results. However, no clear guidance for the implementation of microsimulation models in R exists. In this tutorial, we provide a step-by-step guide to build microsimulation models in R and illustrate the use of this guide on a simple, but transferable, hypothetical decision problem. We guide the reader through the necessary steps and provide generic R code that is flexible and can be adapted for other models. We also show how this code can be extended to address more complex model structures and provide an efficient microsimulation approach that relies on vectorization solutions.

  19. Effectiveness of interactive tutorials in promoting "which-path" information reasoning in advanced quantum mechanics

    Maries, Alexandru; Sayer, Ryan; Singh, Chandralekha

    2017-12-01

    Research suggests that introductory physics students often have difficulty using a concept in contexts different from the ones in which they learned it without explicit guidance to help them make the connection between the different contexts. We have been investigating advanced students' learning of quantum mechanics concepts and have developed interactive tutorials which strive to help students learn these concepts. Two such tutorials, focused on the Mach-Zehnder interferometer (MZI) and the double-slit experiment (DSE), help students learn how to use the concept of "which-path" information to reason about the presence or absence of interference in these two experiments in different situations. After working on a pretest that asked students to predict interference in the MZI with single photons and polarizers of various orientations placed in one or both paths of the MZI, students worked on the MZI tutorial which, among other things, guided them to reason in terms of which-path information in order to predict interference in similar situations. We investigated the extent to which students were able to use reasoning related to which-path information learned in the MZI tutorial to answer analogous questions on the DSE (before working on the DSE tutorial). After students worked on the DSE pretest they worked on a DSE tutorial in which they learned to use the concept of which-path information to answer questions about interference in the DSE with single particles with mass sent through the two slits and a monochromatic lamp placed between the slits and the screen. We investigated if this additional exposure to the concept of which-path information promoted improved learning and performance on the DSE questions with single photons and polarizers placed after one or both slits. We find evidence that both tutorials promoted which-path information reasoning and helped students use this reasoning appropriately in contexts different from the ones in which they had learned

    Students embarking on a bioscience degree course, such as Animal Science, often do not have sufficient experience in mathematics. However, mathematics forms an essential and integral part of any bioscience degree and is essential to enhance employability. This paper presents the findings of a project looking at the effect of mathematics tutorials on a cohort of first year animal science and management students. The results of a questionnaire, focus group discussions and academic performance analysis indicate that small group tutorials enhance students' confidence in maths and improve students' academic performance. Furthermore, student feedback on the tutorial programme provides a deeper insight into student experiences and the value students assign to the tutorials.

  4. Rule Systems for Runtime Verification: A Short Tutorial

    Science.gov (United States)

    Barringer, Howard; Havelund, Klaus; Rydeheard, David; Groce, Alex

    In this tutorial, we introduce two rule-based systems for on and off-line trace analysis, RuleR and LogScope. RuleR is a conditional rule-based system, which has a simple and easily implemented algorithm for effective runtime verification, and into which one can compile a wide range of temporal logics and other specification formalisms used for runtime verification. Specifications can be parameterized with data, or even with specifications, allowing for temporal logic combinators to be defined. We outline a number of simple syntactic extensions of core RuleR that can lead to further conciseness of specification but still enabling easy and efficient implementation. RuleR is implemented in Java and we will demonstrate its ease of use in monitoring Java programs. LogScope is a derivation of RuleR adding a simple very user-friendly temporal logic. It was developed in Python, specifically for supporting testing of spacecraft flight software for NASA’s next 2011 Mars mission MSL (Mars Science Laboratory). The system has been applied by test engineers to analysis of log files generated by running the flight software. Detailed logging is already part of the system design approach, and hence there is no added instrumentation overhead caused by this approach. While post-mortem log analysis prevents the autonomous reaction to problems possible with traditional runtime verification, it provides a powerful tool for test automation. A new system is being developed that integrates features from both RuleR and LogScope.

    Buzzell, Paul R; Chamberlain, Valerie M; Pintauro, Stephen J

    2002-12-01

    This study examined the effectiveness of a series of Web-based, multimedia tutorials on methods of human body composition analysis. Tutorials were developed around four body composition topics: hydrodensitometry (underwater weighing), dual-energy X-ray absorptiometry, bioelectrical impedance analysis, and total body electrical conductivity. Thirty-two students enrolled in the course were randomly assigned to learn the material through either the Web-based tutorials only ("Computer"), a traditional lecture format ("Lecture"), or lectures supplemented with Web-based tutorials ("Both"). All students were administered a validated pretest before randomization and an identical posttest at the completion of the course. The reliability of the test was 0.84. The mean score changes from pretest to posttest were not significantly different among the groups (65.4 plus minus 17.31, 78.82 plus minus 21.50, and 76 plus minus 21.22 for the Computer, Both, and Lecture groups, respectively). Additionally, a Likert-type assessment found equally positive attitudes toward all three formats.

    Full Text Available In Mexico 75.5% of children and young students in elementary and secondary school are at insufficient and elementary levels in mathematics. The purpose of this research is to join the UNESCO initiative by granting quality education, boosted by technology (Rose, 2013. Specifically, the objective is to analyze the impact of using a tutorial video on academic achievement, based on Gestalt psychology stimulating the sensation and perception cognitive capabilities. Using a 50 student sample was used, which was divided into two groups (experimental and control we test whether students that use a tutorial video based on sensation and perception increase their attention and interest to increase academic achievement. The experimental group was a virtual class with tutorial videos on the use of slopes, explanation of the equation, and a virtual graph generator. Both groups were a survey and an exam. The results show that a high impact on the grades and on the perception of knowledge in the experimental group; the average academic achievement of the experimental group was 9.31, against 2 in the control group. Thus, we conclude that the tutorial video presented stimulates cognitive capabilities and improves academic achievement with a 7.3 impact per additional unit of tutorial video, presented as reinforcement of the class.

  8. SFO-Project: The New Generation of Sharable, Editable and Open-Access CFD Tutorials

    2016-11-01

    One of the most common approaches to develop a Computational Fluid Dynamic (CFD) simulation for a new case study of interest is to search for the most similar, previously developed and validated CFD simulation among other works. A simple search would result into a pool of written/visual tutorials. However, users should spend significant amount of time and effort to find the most correct, compatible and valid tutorial in this pool and further modify it toward their simulation of interest. SFO is an open-source project with the core idea of saving the above-mentioned time and effort. This is done via documenting/sharing scientific and methodological approaches to develop CFD simulations for a wide spectrum of fundamental and industrial case studies in three different CFD solvers; STAR-CCM +, FLUENT and Open FOAM (SFO). All of the steps and required files of these tutorials are accessible and editable under the common roof of Github (a web-based Git repository hosting service). In this presentation we will present the current library of 20 + developed CFD tutorials, discuss the idea and benefit of using them, their educational values and explain how the next generation of open-access and live resource of CFD tutorials can be built further hand-in-hand within our community.

  9. Prognostics 101: A tutorial for particle filter-based prognostics algorithm using Matlab

    International Nuclear Information System (INIS)

    An, Dawn; Choi, Joo-Ho; Kim, Nam Ho

    2013-01-01

    This paper presents a Matlab-based tutorial for model-based prognostics, which combines a physical model with observed data to identify model parameters, from which the remaining useful life (RUL) can be predicted. Among many model-based prognostics algorithms, the particle filter is used in this tutorial for parameter estimation of damage or a degradation model. The tutorial is presented using a Matlab script with 62 lines, including detailed explanations. As examples, a battery degradation model and a crack growth model are used to explain the updating process of model parameters, damage progression, and RUL prediction. In order to illustrate the results, the RUL at an arbitrary cycle are predicted in the form of distribution along with the median and 90% prediction interval. This tutorial will be helpful for the beginners in prognostics to understand and use the prognostics method, and we hope it provides a standard of particle filter based prognostics. -- Highlights: ► Matlab-based tutorial for model-based prognostics is presented. ► A battery degradation model and a crack growth model are used as examples. ► The RUL at an arbitrary cycle are predicted using the particle filter

    Full Text Available The need for a change in the university educational model promoted by the establishment of the European Higher Education Area (EHEA has promoted the implementation of numerous proposals for innovation in university teaching. These innovative practices that are based on a process of reflection and analysis of past teaching experience, are helping to improve qualitatively the teaching practice and, consequently, the learning process and outcomes of students, from a process of reflection and analysis of the teaching experience. In this context, this paper focuses on analyzing a specific teaching tool for innovation, the video tutorial, in order to assess its influence on the processes of assimilation of contents and self-learning. In particular, we attempt to show if the video tutorial allows reinforcing the understanding of practical contents that have been previously given by the classical method of masterly exposition. From the analysis of data obtained through a survey directed to a sample of students after experimenting with the teaching tool, it is shown that the video tutorial is considered a very suitable tool to improve the assimilation capacity of the contents taught previously and to acquire higher learning. After performing a regression analysis, the research also shows that students’ attitudes toward multimedia tools and the perceived utility of video tutorial positively influence these capacities. On the contrary, we find that the attitude towards individual learning and the attention paid by the student to the contents of the video tutorial do not affect the level of learning obtained from this tool.

    Diagnostic imaging is under-represented in medical curricula globally. Adaptive tutorials, online intelligent tutoring systems that provide a personalized learning experience, have the potential to bridge this gap. However, there is limited evidence of their effectiveness for learning about diagnostic imaging. We performed a randomized mixed methods crossover trial to determine the impact of adaptive tutorials on perceived engagement and understanding of the appropriate use and interpretation of common diagnostic imaging investigations. Although concurrently engaged in disparate blocks of study, 99 volunteer medical students (from years 1-4 of the 6-year program) were randomly allocated to one of two groups. In the first arm of the trial on chest X-rays, one group received access to an adaptive tutorial, whereas the other received links to an existing peer-reviewed Web resource. These two groups crossed over in the second arm of the trial, which focused on computed tomography scans of the head, chest, and abdomen. At the conclusion of each arm of the trial, both groups completed an examination-style assessment, comprising questions both related and unrelated to the topics covered by the relevant adaptive tutorial. Online questionnaires were used to evaluate student perceptions of both learning resources. In both arms of the trial, the group using adaptive tutorials obtained significantly higher assessment scores than controls. This was because of higher assessment scores by senior students in the adaptive tutorial group when answering questions related to topics covered in those tutorials. Furthermore, students indicated significantly better engagement with adaptive tutorials than the Web resource and rated the tutorials as a significantly more valuable tool for learning. Medical students overwhelmingly accept adaptive tutorials for diagnostic imaging. The tutorials significantly improve the understanding of diagnostic imaging by senior students. Crown Copyright

    Full Text Available In the new setting promoted by the European Higher Education Area, university guidance and tutorials have become more important than ever. We understand tutorials as part of the teaching responsibility in which a more personal interaction between professor and student, professor and novice teacher, or student and student is established, and whose goal is to guide learning according to the individual characteristics and learning styles of the individuals involved. Now is the time to set up guidance and tutorials systems for students –both during the training process and in their first professional steps– and for novice teachers also. Among such systems we can mention professor coaching, peer mentoring, professional tutoring in training centres or mentoring of an experienced university professor on the novice teacher.

    BACKGROUND: Electrocardiogram (ECG) interpretation is of great importance for patient management. However, medical students frequently lack proficiency in ECG interpretation and rate their ECG training as inadequate. Our aim was to examine the effect of a standalone web-based ECG tutorial...... and to assess the retention of skills using multiple follow-up intervals. METHODS: 203 medical students were included in the study. All participants completed a pre-test, an ECG tutorial, and a post-test. The participants were also randomised to complete a retention-test after short (2-4 weeks), medium (10.......6), respectively). When comparing the pre-test to retention-test delta scores, junior students had learned significantly more than senior students (junior students improved 10.7 points and senior students improved 4.7 points, p = 0.003). CONCLUSION: A standalone web-based ECG tutorial can be an effective means...

    2015-09-01

    To determine whether cytopathology whole slide images and virtual microscopy adaptive tutorials aid learning by postgraduate trainees, we designed a randomized crossover trial to evaluate the quantitative and qualitative impact of whole slide images and virtual microscopy adaptive tutorials compared with traditional glass slide and textbook methods of learning cytopathology. Forty-three anatomical pathology registrars were recruited from Australia, New Zealand, and Malaysia. Online assessments were used to determine efficacy, whereas user experience and perceptions of efficiency were evaluated using online Likert scales and open-ended questions. Outcomes of online assessments indicated that, with respect to performance, learning with whole slide images and virtual microscopy adaptive tutorials was equivalent to using traditional methods. High-impact learning, efficiency, and equity of learning from virtual microscopy adaptive tutorials were strong themes identified in open-ended responses. Participants raised concern about the lack of z-axis capability in the cytopathology whole slide images, suggesting that delivery of z-stacked whole slide images online may be important for future educational development. In this trial, learning cytopathology with whole slide images and virtual microscopy adaptive tutorials was found to be as effective as and perceived as more efficient than learning from glass slides and textbooks. The use of whole slide images and virtual microscopy adaptive tutorials has the potential to provide equitable access to effective learning from teaching material of consistently high quality. It also has broader implications for continuing professional development and maintenance of competence and quality assurance in specialist practice. Copyright © 2015 Elsevier Inc.

  4. Tutorial on the Psychophysics and Technology of Virtual Acoustic Displays

    Wenzel, Elizabeth M.; Null, Cynthia (Technical Monitor)

    1998-01-01

    Virtual acoustics, also known as 3-D sound and auralization, is the simulation of the complex acoustic field experienced by a listener within an environment. Going beyond the simple intensity panning of normal stereo techniques, the goal is to process sounds so that they appear to come from particular locations in three-dimensional space. Although loudspeaker systems are being developed, most of the recent work focuses on using headphones for playback and is the outgrowth of earlier analog techniques. For example, in binaural recording, the sound of an orchestra playing classical music is recorded through small mics in the two "ear canals" of an anthropomorphic artificial or "dummy" head placed in the audience of a concert hall. When the recorded piece is played back over headphones, the listener passively experiences the illusion of hearing the violins on the left and the cellos on the right, along with all the associated echoes, resonances, and ambience of the original environment. Current techniques use digital signal processing to synthesize the acoustical properties that people use to localize a sound source in space. Thus, they provide the flexibility of a kind of digital dummy head, allowing a more active experience in which a listener can both design and move around or interact with a simulated acoustic environment in real time. Such simulations are being developed for a variety of application areas including architectural acoustics, advanced human-computer interfaces, telepresence and virtual reality, navigation aids for the visually-impaired, and as a test bed for psychoacoustical investigations of complex spatial cues. The tutorial will review the basic psychoacoustical cues that determine human sound localization and the techniques used to measure these cues as Head-Related Transfer Functions (HRTFs) for the purpose of synthesizing virtual acoustic environments. The only conclusive test of the adequacy of such simulations is an operational one in which

    2014-03-01

    Materials from Tutorials in Introductory Physics, originally designed and implemented by the Physics Education Group at the University of Washington, were used in modified form as interactive lectures under conditions significantly different from those suggested by the curriculum developers. Student learning was assessed using tasks drawn from the physics education research literature. Use of tutorials in the interactive lecture format yielded gains in student understanding comparable to those obtained through the canonical tutorial implementation at the University of Washington, suggesting that student engagement with the intellectual steps laid out in the tutorials, rather than the specific strategies used in facilitating such engagement, plays the central role in promoting student learning. We describe the implementation details and assessment of student learning for two different tutorials: one focused on mechanical waves, used at North Dakota State University, and one on Galilean relativity, used at Western Washington University. Also discussed are factors that may limit the generalizability of the results.

    2007-09-01

    Computer-aided instruction (CAI) was developed to teach veterinary students how to make blood smears. This instruction was intended to replace the traditional instructional method in order to promote efficient use of faculty resources while maintaining learning outcomes and student satisfaction. The purpose of this study was to evaluate the effect of a computer-aided blood smear tutorial on 1) instructor's teaching time, 2) students' ability to make blood smears, and 3) students' ability to recognize smear quality. Three laboratory sessions for senior veterinary students were taught using traditional methods (control group) and 4 sessions were taught using the CAI tutorial (experimental group). Students in the control group received a short demonstration and lecture by the instructor at the beginning of the laboratory and then practiced making blood smears. Students in the experimental group received their instruction through the self-paced, multimedia tutorial on a laptop computer and then practiced making blood smears. Data was collected from observation, interview, survey questionnaires, and smear evaluation by students and experts using a scoring rubric. Students using the CAI made better smears and were better able to recognize smear quality. The average time the instructor spent in the room was not significantly different between groups, but the quality of the instructor time was improved with the experimental instruction. The tutorial implementation effectively provided students and instructors with a teaching and learning experience superior to the traditional method of instruction. Using CAI is a viable method of teaching students to make blood smears.

    Full Text Available We have investigated the efficacy of on-line, multimedia learning modules (MLMs as preparation for in-class, lecture-based tutorials in electromagnetism in a physics course for natural science majors (biology and marine science. Specifically, we report the results of a multiple-group pre/post-test research design comparing two groups receiving different treatments with respect to activities preceding participation in Tutorials in Introductory Physics. The different pre-tutorial activities were as follows: (1 students were assigned reading from a traditional textbook, followed by a traditional lecture; and (2 students completed on-line MLMs developed by the Physics Education Research Group at the University of Illinois at Urbana Champaign (UIUC, and commercially known as FlipItPhysics. The MLM treatment group earned significantly higher mid-term examination scores and larger gains in content knowledge as measured by the Conceptual Survey of Electricity and Magnetism (CSEM. Student attitudes towards “reformed” instruction in the form of active-engagement tutorials were also improved. Specifically, post-course surveys showed that MLM-group students believed class time was more effective and the instructor was more clear than reported by non-MLM students, even though there was no significant difference between groups with respect to in-class activities and the same instructor taught both groups. MLM activities can be a highly effective tool for some student populations, especially when student preparation and buy-in are important for realizing significant gains.

    2009-12-01

    Full Text Available As the number of completely sequenced microbial genomes continues to rise at an impressive rate, it is important to prepare students with the skills necessary to investigate microorganisms at the genomic level. As a part of the core curriculum for first-year graduate students in the biological sciences, we have implemented a web-based tutorial to introduce students to the fields of comparative and functional genomics. The tutorial focuses on recent computational methods for identifying functionally linked genes and proteins on a genome-wide scale and was used to introduce students to the Rosetta Stone, Phylogenetic Profile, conserved Gene Neighbor, and Operon computational methods. Students learned to use a number of publicly available web servers and databases to identify functionally linked genes in the Escherichia coli genome, with emphasis on genome organization and operon structure. The overall effectiveness of the tutorial was assessed based on student evaluations and homework assignments. The tutorial is available to other educators at http://www.doe-mbi.ucla.edu/~strong/m253.php.
