- Abstract
In this paper, we analyze the motion of a falling Slinky, starting from rest and initially suspended from one of its ends. It is well-known that under these conditions, the Slinky moves in an unusual way: its lower end remains at rest until the upper end collides with it - as if gravity were being challenged! We conducted a literature review and identified that the most widely disseminated explanation for this levitation phenomenon of the Slinky's base during the Slinky's fall relies on the concept of information (and does not seem to please many). We show that such a phenomenon can be explained - and reproduced through a computer simulation using a simple model - without the notion that "there is a finite time for the information that the Slinky was released at its top to reach its bottom".

New structural systems in civil construction are always emerging, and therefore a performance evaluation is necessary. For this evaluation, laboratory tests are necessary, but, due to the scarcity of research centers, numerical simulations have emerged as an alternative. For better reliability in the results obtained in the simulation, a mesh test is necessary, verifying the influence of the results. In this paper, the analysis of are two main types of mesh (tetrahedral and hexahedral) and several possible discretization sizes, aiming to evaluate the parameters in a numerical simulation of a specimen requested with 3-point static bending. Two mesh types and three sizes (1mm, 5mm and 10mm) were adopted. Through the obtained results, it can be reached that the tetrahedral mesh obtained better results. It was also possible to achieve that the mesh size did not change the results of stresses and displacements in the contour of the part, only influencing the results of stresses in the interior.

In general, the identification of probability distributions for time between arrivals and the covariates that affect them, get a superficial treatment in papers on production engineering. The main goal of this paper is to analyze the data on the time between arrivals for batches at the quality control department in a food company. A Weibull distribution, with two parameters, was used in the statistical modeling - a quantitative approach. Scale and shape was estimated by the Maximum Likelihood Method. A regression Weibull model was considered to evaluate inferences for the mean and median times between arrivals and to detect important factors affecting the variability in data sets. Considering some covariates, the Weibull distribution was found to have a good fit for the data. These results allow for a more reliable modeling of the quality control department for discrete event simulation. [ABSTRACT FROM AUTHOR]

In this paper we introduce Schrödinger's operators in a naive and unpretentious way, but with some precision and didactics. The most studied periodic and random potential types are mentioned and, by numerical simulation, compare the eigenvalues of an operator's truncated matrix with a periodic potential and the same potential disturbed by an evenly distributed continuous random variable. We evaluated the magnitude of the random variable required to produce a significant difference between the eigenvalue sets. [ABSTRACT FROM AUTHOR]

A modest archetypal of satiation is that it boils down primarily to two categories of signals transmitted from the gastrointestinal tract to the brain: stomach and intestine sensing and metabolism. Novel investigations endow us with the view that an extension of this traditional model is conceivable and called for, wherein intestinal satiation is the byproduct not only from signals related to the caloric content of ingested nutrients, but also from noncaloric properties of ‘tastant molecules’ in foodstuff. On this paper we discuss a recently published paper regarding the impact of tastants (e.g., noncaloric substance widely used as taste enhancers) on hunger and food intake. We gather the in vivo results (nasoduodenal infusions of tastants) with a recently developed mathematical model for ghrelin by the author and co-workers and we successfully replicate in silico part of the findings. The key results from the abovementioned paper and replicated herein is that tastant can inhibit hunger; with different levels of impact, umami being the strongest one, and the union of them being even stronger.

In this paper we argue about the use of modeling cycles from David Hestenes' framework as an alternative to guide actions combining computer-based simulations and experimental activities. From a strategy that challenges students to explore the domain of validity of theoretical models and to control a diversity of representation tools, we suggest that the methodology presented here has potential to promote a more coherent conception of Science, in which students perceive its developing as something typically human in which scientists attempt to construct representations of physical phenomena, with varying degree of accuracy and limited context. Finally, we present some possibilities to use the softwares Modellus and Tracker to explore the boundaries of the validity domain of the theoretical model known as simple pendulum during a modeling cycle. Applying with Brazilian students from a professional Master's Degree in Physics Education, the cycles were important to highlight the differences between the theoretical model studied and the empirical phenomena, helping to improve their understanding of the process of scientific modeling. Some practical issues about this proposal implementation and another involving Newton's law of cooling are also discussed in this paper [ABSTRACT FROM AUTHOR]

We have recently developed a software to simulate a given physical phenomenon, without the need of knowing its corresponding equation of motion. This procedure is actually intended to illustrate the behavior of dynamical variables of interest, such as position, velocity, acceleration and energy. In our work, we present analytical solutions for each case under consideration; numerical solutions carried out by means of the finite difference method are presented as well. The harmonic oscillator is a moving periodical system, with a well-defined equilibrium position. We shall here present an overview of the general problem to be solved and a number of special cases shall be worked out in details. As one of the purposes of this article is to encourage readers to use numerical approaches to inspect physical problems, we shall discuss in a simple and direct way the numerical solutions of a mechanical oscillator. We also contemplate the behavior of the energy function and point out under which particular situations it is conserved. To validate the numerical method implemented in our paper, we compare the analytical solutions we derive with the results obtained by numerical computations. [ABSTRACT FROM AUTHOR]

COMPUTER simulation , *RESIDUAL stresses , *ELECTRIC distortion , *STEEL bars , *LUBRICATION & lubricants , *STRAINS & stresses (Mechanics) - Abstract
The drawing process of steel bars is usually used to check better dimensional accuracy and mechanical properties to the material. In the other hand, the major concern found in manufacturing axes through this process is the appearance of distortion of shape. Such distortions are directly linked to the accumulation of residual stresses generated during the processes. As a result, this paper aims to study the influence of process parameters such as shape of puller, speed and lubrication used in wire drawing analyzing the accumulation of residual stress after the process. The stress analysis was performed by FEM being used two simulation software: Simufact.formingGP®and DeformTM. Through these analyzes, it was found that the shape of how the bar is pulled causes a reduction of up to 100 MPa in residual stresses in the center of the bar, which represents an important factor in the study of the possible causes of the distortion. As well as factors speed and homogeneity of lubrication significantly altered the profile of residual stresses in the bar. [ABSTRACT FROM AUTHOR]

This paper describes how was implemented a computer simulation of an ionizing radiation detection system similar to those found in traditional modern Physics laboratories. The simulation models a system with a 'source' of photons of arbitrarily chosen energies, a 'detector' that behaves like a Geiger-Müller detector and the effect of different attenuating materials with variable thickness inserted between the source and the detector. Details of the calculation of the radiation attenuation using data from the United States National Institutes of Standards and Technology (NIST) database are presented, and employed to explore characteristics of the radiation interaction with matter, from cross sections to statistical fluctuations. Examples and suggestions of exploratory activities are also presented. The simulation was used with two groups of about undergraduate students from a distance learning Physics course at UFSC in the beginning of 2011, along with the execution of the real experiment. Throughout the text, comments on the motivations and problems of using simulations in this context are discussed. Finally, it is discussed how this work relates to the main goals of introductory Physics laboratories, according to an American Physical Society Committee specifically created to evaluate that.

This paper presents, initially, different frameworks about the interface Technology and Science into the educational context, followed by the report of three independent experiences related to the study of the use of computer modelling in Science teaching. These experiences, focusing on knowledge, not on technology, happened in a specific moment when the striking advance of computer technology brought computers into classrooms. Subsequently, it is presented a report about the development of a research program about the infusion of computer environments in Physics teaching based on the use of quantitative, semi-quantitative and qualitative computer modelling environment into the Brazilian context [ABSTRACT FROM AUTHOR]

In this paper, we present the theoretical and methodological basis of the preparation and production of teaching materials supported by computer resources such as animations, simulations, games and virtual labs, for use in teaching physics. The materials were built with hypermedia resources, joining the concepts of nonlinearity, hypertext and multimedia (animations, simulations, sound) in one language. The hypermedia concept adopted states it is a means to an end, a language and an audiovisual product enabling the association with the concept of learning object which allows the creation of digital materials with different granularities ranging from one activity to a full course. If the courseware is created with this concern, it can be used in different learning environments under different platforms, and provide a basis for the evaluation of its use in different teaching situations. The topics discussed (animations, simulations, games and virtual labs) are part of content in high school and in the disciplines of basic physics of higher education. The materials are available on an open page on the Internet (HTTP://www.fsc.ufsc.br/~tati/webfisica/index.html) and some of them can also be accessed from the MEC's database of educational objects [ABSTRACT FROM AUTHOR]

This paper presents results of an exploratory case study which the main objectives were to: evaluate the receptivity of the students regarding the Peer Instruction (PI) method and the use of computers of the UCA project (Brazilian version of the project One Laptop per Child); investigate if the discussion between colleagues promotes the convergence to the correct answer in concept tests, as it has been pointed in literature; and investigate the viability of using the UCA computers as a voting system to the methodology. The study was conducted in a class of 34 students in the third year of a Federal Public High School over an instructional sequence on topics of Electromagnetism. In this study we observed that the discussion among colleagues proved fruitful, allowing the participation of students and leading to the convergence to the correct answer. We conclude that this methodology can be successfully implemented in the context of a High School classroom using the UCAs as a voting system, given the conditions of infrastructure to use them for the duration of a lesson (e.g. charging of the batteries). It should be emphasized that the adoption of PI can be done in a complementary manner to the activities of problem solving, experimental work and/or computer simulation, aimed at teaching.

The low cost experiments represent an alternative to the lack of laboratories in schools, as well as being a way on with we can conduct the students to Science through the use of materials easily obtainable and available in their daily lives. The use of videos and simulations in support of the teaching-learning process in High School Physics courses, is also a useful tool for students to understand Science as a form of representation of natural phenomena. It is common to these students the idea that Science is purely abstract and detached from reality, because they are based on situations, almost always ideal, that arise in the exercises in Physics. The process of moving from concrete to abstract is often forgotten, as it is only presented to the student the abstract piece. This paper aims at analyzing the process of teaching and learning in a Physics class with the use of those resources in a bundle, addressing a theme often omitted from school textbooks: the dynamics of rotation. We present an experimental kit designed and produced by us, as well as a software, of our own, and make several suggestions for joint implementation of these two elements. [ABSTRACT FROM AUTHOR]

Underground mine planning is an important element for achieving project re-alization in the current highly competitive scenario. This is due to the peculiarities of the underground mines, where it is difficult to obtain profound knowledge about the body and location of the underground excavations. Computer applicationsspatially visualize the ore body with its geological sec-tions and mineral formation contours. This visual is in 3D that facilitates the alloca-tion of major mine development services. Although such resources are available, their mining applications are generally developed for open pit mining methods, and is still incipient for underground mine-development methodologies. With the use of applications for mine development and planning, and the simi-larity of existing mines, it was possible to prepare the infrastructure project for a specific underground mine, and a 3D view of its underground openings. It was also possible to develop a methodology for drawing the galleries described. This paper deals with the selection of mining methods for a major simulated mineral deposit and describes breakthroughs of underground mine development de-sign using a commercial mining application.

As simulações são realizadas a partir de dados reais morfológicos extraídos de pacientes e simulações da função mandibular. Os resultados obtidos fornecem informações relevantes como a distribuição espacial e temporal das colisões dentárias nas arcadas inferior e superior e a orientação do plano médio destas colisões em relação ao plano oclusal. A visualização das colisões dentárias é apresentada em forma de mapa de calor e por distribuição em quadrantes dentários permitindo a observação de indicadores individualizados e métricas comparativas para a compreensão do fenômeno. Dental malocclusion can result in damage to the entire stomatognathic system. Its study allows professionals to infer the necessary data to achieve success in medical and/or dental treatments (surgical or otherwise), occlusal stability and orofacial harmony. This paper presents a model to simulate and analyze information relevant to the dental occlusion process and its implications. The simulations are performed based on real morphological data from patients and simulations of the mandibular function. The results of this paper provide relevant information such as the spatial and temporal distribution of dental collisions in the lower and upper arches and the orientation of the median plane of these collisions in relation to the occlusal plane. The visualization of the dental collisions is presented in the form of a heat map and by distribution in dental quadrants, which allows the observation of individualized indicators and comparative metrics for the understanding of the phenomenon.

Abstract Computer models and simulations have provided enormous benefits to researchers in the natural and social sciences, as well as many areas of philosophy. However, to date, there has been little attempt to use computer models in the development and evaluation of metaphysical theories. This is a shame, as there are good reasons for believing that metaphysics could benefit just as much from this practice as other disciplines. In this paper I assess the possibilities and limitations of using computer models in metaphysics. I outline the way in which different kinds of model could be useful for different areas of metaphysics, and I illustrate in more detail how agent-based models specifically could be used to model two well-known theories of laws: David Lewis’s "Best System Account" and David Armstrong's "Nomic Necessitation" view. Some logically possible processes cannot be simulated on a standard computing device. I finish by assessing how much of a threat this is to the prospect of metaphysical modeling in general.

Resumo O artigo avalia o impacto da inserção de áreas verdes na diminuição do estresse térmico do pedestre em dias com desconforto por calor. Está focado em duas importantes ações voltadas à mobilidade urbana que consideraram a inserção de vegetação como estratégia de requalificação da paisagem urbana, em Curitiba: (1) o projeto para a implantação do primeiro metrô do Estado do Paraná e (2) a transformação da antiga Rodovia Federal BR-116 em via urbana. Considerando recortes urbanos relacionados a tais projetos como áreas de estudo (Sete de Setembro e Linha Verde), o objetivo da pesquisa é propor um índice que indique a cobertura vegetal necessária para haver reduções na temperatura do ar na escala do pedestre, considerando o período diurno em situação de verão. Adicionalmente, analisa-se o impacto no conforto térmico, por meio do universal thermal climate index (UTCI). Para isso, foram utilizadas medições em campo para a coleta de dados microclimáticos, bem como simulações computacionais com a ferramenta ENVI-met. Os resultados apontam que seria necessário um aumento de cerca de 70% de cobertura vegetal para uma redução de 1°C na temperatura ambiente média da área estudada, o que indica o potencial de resfriamento de áreas vegetadas em situações urbanas. Abstract This paper analyses the impact of the introduction of green areas on the reduction of pedestrian heat stress in days with heat discomfort. The paper focuses on two relevant urban mobility initiatives that use greenery enhancement as a strategy for the requalification of urban environments in Curitiba: (1) the proposal of the first underground railway system in the state and (2) the transformation of an interstate highway into an urban avenue. Segments of such projects are evaluated as study areas (Sete de Setembro and Linha Verde) with the aim of proposing an index that estimates the vegetation cover needed to promote air temperature drops at the pedestrian scale during daytime in summer. Additionally, the study analyses the impact on thermal comfort through the universal thermal climate index (UTCI). For that purpose, we carried out a field study where we monitored relevant meteorological data, as well as computer simulations using the ENVI-met model. Results suggest that an increase of 70% in vegetated fraction would be needed to offset 1°C in mean ambient temperature in the area analysed, which represents the cooling potential of vegetation fractions in urban conditions.

In a social-environmental modeling course, students need to learn complementary skills that include the conceptualisation of a model, different modeling paradigms, computer pro- gramming, and the process of rigorously converting ideas and data into a computational program using a given toolkit. Such topics need to be taught in parallel in order to keep a heterogeneous audience motivated. Based on the experience with multidisciplinary au- diences, this paper describes a socio-environmental modeling course that explores three modeling paradigms: System dynamics, Cellular automata, and Agent-based modeling. We also present a small tutorial with some examples developed for the course.

Neste artigo convidamos os leitores a descobrir o mundo dos "experimentos computacionais" (ou simulações computacionais) para plasma espacial. O experimento computacional é semelhante ao experimento tradicional realizado em laboratório. Ele não é, e não será capaz de solucionar todos os problemas físicos que permanecem incompreendidos, mas fornece uma poderosa ferramenta para auxiliar os físicos (cientistas) a buscar soluções dos mesmos. Apresentamos neste trabalho algumas características das simulações computacionais e exemplos onde estas simulações podem ser aplicadas. Para uma melhor compreensão é recomendável que o leitor tenha conhecimentos básicos em física de plasmas e eletromagnetismo, uma vez que utilizamos estes conhecimentos para desenvolver este trabalho. In this paper we invite the readers to discover the world of "computational experiments" (or computer simulation) of space plasmas. The computational experiment is similar to those traditionally made in laboratory. It is not purpose to solve all the physical problems that remain misunderstood, but provides a powerful tool to help physicists (scientists) in the search of their solution. We present some characteristics of computer simulations and examples where these simulations can be applied. For a better understanding of this paper it is recommended that the reader have a basic knowledge in plasma physics and electromagnetism, since we use these concepts to develop this work.

Biomedical simulation is an effective educational complement for healthcare training, both at undergraduate and postgraduate level. It enables knowledge, skills and attitudes to be acquired in a safe, educationally orientated and efficient manner. In this context, simulation provides skills and experience that facilitate the transfer of cognitive, psychomotor and proper communication competences, thus changing behavior and attitudes, and ultimately improving patient safety. Beyond the impact on individual and team performance, simulation provides an opportunity to study organizational failures and improve system performance. Over the last decades, simulation in healthcare had a slow but steady growth, with a visible maturation in the last ten years. The simulation community must continue to provide the core leadership in developing standards. There is a need for strategies and policy development to ensure its coordinated and cost-effective implementation, applied to patient safety. This paper reviews the evolutionary movements of biomedical simulation, including a review of the Portuguese initiatives and nationwide programs. For leveling knowledge and standardize terminology, basic but essential concepts in clinical simulation, together with some considerations on assessment, validation and reliability are presented. The final sections discuss the current challenges and future initiatives and strategies, crucial for the integration of simulation programs in the greater movement toward patient safety.

A Simulação Computacional de Ambientes Históricos constitui um novo campo de conhecimento, que vem atuando como uma importante ferramenta à representação do passado e presente das cidades, contribuindo na compreensão de sua evolução histórica e no seu planejamento. Visando a despertar a sensibilidade em reconhecer e valorizar o produto arquitetônico histórico e seus elementos, bem como construir um olhar diferenciado sobre o futuro da cidade, esta dissertação reforça e traz à realidade o discurso que encara o passado e o presente não mais em épocas distintas, mas em uma "conversa" simultânea de muito respeito e consideração. O objetivo deste trabalho é sistematizar procedimentos metodológicos adequados, por meio do uso de programas computacionais, para a simulação do Patrimônio Histórico Arquitetônico. O trabalho inicia apontando dificuldades de manutenção e recuperação de edifícios históricos, fruto da falta de uma cultura que valorize esse patrimônio, sugerindo sua simulação virtual, como forma de contribuição para seu resgate e sua conseqüente valorização na memória coletiva. No segundo momento, é feita uma revisão do tema em exemplos produzidos em contextos semelhantes, para, depois, testar uma metodologia de reconstituição virtual no objeto de estudo escolhido, situado na praça Dante Alighieri, em Caxias do Sul. Resultado de diversas análises de aplicações, potencialidades e limites, contando com o auxílio da restituição fotogramétrica e de diversos programas de computação gráfica, a metodologia proposta percorre um caminho que começa com a busca e seleção da foto de época, e termina com a produção de modelos geométricos tridimensionais, com vistas ao desenvolvimento de futuros trabalhos de reprodução digital de todo o entorno da Praça em suas diferentes fases, ao longo da História. Esses procedimentos metodológicos buscaram a documentação não apenas de suas formas arquitetônicas, mas do processo de trabalho adotado, constatando além da viabilidade do método, como o potencial que os recursos da simulação computacional de ambientes históricos apresenta, tanto nos aspectos educativos quanto na valorização do patrimônio arquitetônico existente nas cidades. The Computer Simulation of Historic Environments composes a new field of knowledge which has been acting as an important tool in representing the past and the present of the cities, contributing to the understanding of the historical evolution and its planning. Aiming to awaken sensitivity in recognizing and valuing the architectural historical product and its elements as well as build up a different look over the future of the city, this dissertation reinforces and brings to reality the speech that faces past and present not in distinct times anymore, but in a simultaneous "talk" filled with respect and consideration. The objective of this paper is to systematize proper methodological procedures, using computer programs to simulate the Architectural Historical Heritage. The paper starts pointing out difficulties in maintaining and recovering historical buildings, results of lack of a culture that values this heritage, suggesting its virtual simulation as a way of contribution to the rescue and consequent valorization in collective memory. In a second moment, a review of the theme in examples produced in similar contexts to later test a methodology of virtual reconstitution in the chosen object of study located at Dante Alighieri Square in Caxias do Sul. As a result of several analysis of applications, potentialities and limits, and with the help of photogrammetric restitution as well of several programs of graphic computing, the proposed methodology starts with the search and selection of the picture of the time, and ends with the production of its virtual tridimensional image, aiming the development of future works of virtual reproduction of the surroundings of the Square in its different phases along the History. These methodological procedures aimed the documentation not only of their architectural forms but also of the work process adopted evidencing both the feasibility of the method and the potential that the computer simulation of historical settings presents in educational aspects and in the valorization of the architectural heritage of the cities.

The building of the School of Architecture and Urbanism of the University of São Paulo (FAUUSP), in the city of São Paulo, inaugurated in 1969 and listed in 1982, is a landmark of the São Paulo School of Modern Architecture, expressing a synthesis between structure, space and environment. The 40% translucid roof area raises questions about the impact of incident solar radiation during the warmest period of the year upon internal spaces' thermal and daylight conditions. This paper presents technical work, including thermal and daylighting studies focusing on the studio spaces and classrooms, examining the improvements brought by the refurbishment of the roof in 2014, in which the domos were replaced. The environmental assessment included analytical studies carried out for the refurbishment project. Among the results, it was noted that the glare associated with the original design was eliminated with the new skylight of milky acrylic, creating a homogeneous lighting environment under the big roof. On the other hand, the uncomfortable thermal conditions were ameliorated by reducing peak internal temperatures by 4 °C on a warm day due to higher ventilation rates achieved with the lifted skylights. However, the discomfort was not eliminated since peak temperatures reach 30 °C during the year's warmest days. O edifício da Faculdade de Arquitetura e Urbanismo da Universidade de São Paulo (FAUUSP), na cidade de São Paulo, inaugurado em 1969 e tombado em 1982, é um marco da Escola Paulista de Arquitetura Moderna, expressando uma síntese entre estrutura, espaço e ambiente. A área de 40% de cobertura translúcida levanta questionamentos sobre o impacto da radiação solar incidente, durante o período mais quente do ano, nas condições luminosas e térmicas do interior. São apresentados neste artigo estudos de investigação técnica sobre as questões térmicas e de iluminação natural, com foco nos espaços dos estúdios e salas de aula, examinando os efeitos promovidos pela reforma da cobertura de 2014, que promoveu a troca dos domos. As análises de desempenho incluíram estudos analíticos realizados para o projeto da reforma. Dentre os resultados, viu-se que os ofuscamentos inerentes ao projeto original foram eliminados com o novo fechamento em acrílico leitoso, criando um ambiente luminoso homogêneo, sob a grande cobertura. Já as condições térmicas foram amenizadas com a redução de temperaturas internas máximas em 4 oC em um dia quente, devido ao aumento da ventilação alcançado com o levantamento das claraboias, porém o desconforto não foi eliminado, uma vez que as temperaturas máximas atingem por volta de 30 °C nos períodos mais quentes do ano.
