This work describes a new approach to gesture mapping in a performance with a traditional musical instrument and live electronics based upon theories of embodied music cognition (EMC) and musical gestures. Considerations on EMC and how gestures affect the experience of music inform different mapping strategies. Our intent is to enhance the expressiveness and the liveness of performance by tracking gestures via a multimodal motion capture system and to use motion data to control several features of the music. After a review of recent research in the field, a proposed application of such theories to a performance with electric guitar and live electronics will follow, focusing both on aspects of meaning formation and motion capturing.

Epidemiologic studies of aggressive periodontitis have used different study designs and a range of examination methods and case definitions, and this greatly complicates the study of disease prevalence in populations. The wide range of disease case definitions, in particular, profoundly impacts the reported rate of disease, and the use of a standard disease definition is strongly recommended. Surveys of aggressive periodontitis that use only clinical examinations, without radiographic examination to confirm the presence of a distinctive pattern of tissue loss, may overestimate the prevalence of this disease, particularly when a low threshold of attachment loss is used. The prevalence of aggressive periodontitis varies significantly between populations, and differences in race/ethnicities seem to be a key factor. Studies consistently show that aggressive periodontitis is most prevalent in Africa and in populations of African descent and is least prevalent in Caucasians in Europe and North America. Among children and young adults the prevalence of this disease is higher in older than in younger age groups. Most studies show comparable disease prevalence in male and female subjects. These findings show that aggressive periodontitis is a significant health problem in certain populations. This review also highlights a lack of information on the epidemiology and demographics of this disease in many parts of the world, particularly in Asia and Africa. Epidemiologic studies of aggressive periodontitis in high-risk populations are important and could provide vital data on the determinants of this disease, and this information is needed for the establishment of effective health-promotion measures.

Known radiation emission mechanisms in plasmas include bremmstrahlung (or free-free emission), gyro- and synchrotron radiation, cyclotron maser, and plasma emission. For unmagnetized plasmas, only bremmstrahlung and plasma emissions are viable. Of these, bremmstrahlung becomes inoperative in the absence of collisions, and the plasma emission requires the presence of electron beam, followed by various scattering and conversion processes. The present Letter proposes a new type of radiation emission process for plasmas in a state of thermodynamic quasi-equilibrium between particles and enhanced Langmuir turbulence. The radiation emission mechanism proposed in the present Letter is not predicted by the linear theory of thermal plasmas, but it relies on nonlinear wave-particle resonance processes. The electromagnetic particle-in-cell numerical simulation supports the new mechanism.

This paper discusses an automated approach to database change management throughout the companies’ development workflow. By using automated tools, companies can avoid common issues related to manual database deployments. This work was motivated by analyzing usual problems within organizations, mostly originated from manual interventions that may result in systems disruptions and production incidents. In addition to practices of continuous integration and continuous delivery, the current paper describes a case study in which a suggested pipeline is implemented in order to reduce the deployment times and decrease incidents due to ineffective data controlling.

A criatividade é um fator essencial para a competitividade dos produtos e o sucesso das empresas. Existe uma série de técnicas criativas que podem ser utilizadas por equipes de projeto de produto. Porém, ocorrem dificuldades na aplicação sistemática dessas técnicas no momento de gerar as concepções de projeto. O objetivo deste trabalho é discutir o uso de técnicas criativas para a geração de ideias de produtos durante o Processo de Desenvolvimento de Produtos (PDP). Foi realizado um estudo experimental por meio do desenvolvimento de um produto que auxilie no transporte de crianças. O desenvolvimento do produto foi realizado até a etapa de projeto conceitual. Para isso, foi utilizado o jogo Creative Sketch na geração de ideias, assim como, técnicas de avaliação e seleção de concepções de projeto para eleger as concepções mais adequadas aos requisitos de projeto. A utilização do jogo possibilitou a geração de 72 ideias em um curto período de tempo. Além do jogo, utilizaram-se o método da síntese funcional e a técnica da matriz morfológica para a geração de alternativas, assim como o método de Pugh para a seleção das melhores alternativas. Como resultado desse processo obtiveram-se duas concepções de produto que atenderam aos requisitos de projeto estabelecidos. Palavras-chave: Criatividade, Técnicas para a geração de ideias, PDP, Jogo, Seleção de concepções.

The goal this article is to show an alternative to the process of making orthoses of a lower limb through of 3D scanning system of cost low. This alternative eliminates the plaster process traditionally utilized in the manufacture of orthoses of the lower limb. Therefore, was done an analysis of the manufacturing process orthoses in a specialist manufactory in a Porto Alegre – RS city. After that was done a 3D scanning in a subject for verification of possibility to make a virtual 3D model of the scanned leg. The 3D scanner utilized during the 3D scanning process was the Kinect device of the Microsoft. Thus, the manufacturing process orthoses by 3D scanning obtained satisfactory results, may be a solution for replaced of plaster model in the manufacturing process. The work is in progress for verification and analysis of precision between the plaster models and virtual model obtained through of the low-cost 3D scanning system.

This work presents the HyperCAL 3D, an application to support the teaching and learning process of Descriptive Geometry through the study of solid objects. The methodology used for its implementation and the main features of the application are described. A selection of concepts was carried out to determine the functional structure of the software should have. From this, the main features were modeled through processes of vector geometry equivalent to that used in Descriptive Geometry. The main features introduced include the projection process, the representation of hidden lines in the three-dimensional model and the projections, successive auxiliary views in real time, and the intersection process. All these tools are implemented in an application that aids the learning process of the students and the teaching procedures of professors.

This work aims to pre-operatively manufacture custom-made low-cost implants and physical models (biomodels) of fractured skulls. The pre-DOI: operative manufacturing of biomodels and implants allows physicians to study and plan surgery with a greater possibility of achieving the expected result. Customization contributes to both the esthetic and functional outcome of the implant because it considers the anatomy of each patient, while the low cost allows a greater number of people to potentially benefit. From CT images of a fractured skull, a CAD model of the skull (biomodel) and a restorative implant were constructed digitally. The biomodel was then physically constructed with 3D Printing, and Incremental Sheet Forming (ISF) was used to manufacture the implant from a sheet of pure grade 2 titanium. Before cutting the implant’s final shape from a pre-formed sheet, heat treatment was performed to avoid deformations caused by residual stresses generated during the ISF process. A comparison of the dimensions of the implant and its respective CAD biomodel revealed geometric discrepancies that can affect both functional and aesthetic efficiency. Nevertheless, the final shape preserved symmetry between the right and left sides of the skull. Electron microscopy analysis did not indicate the presence of elements other than pure titanium. Dimensional variability can be decreased with changes in the manufacturing process (i.e., forming and cutting) and the heating ramp. Despite biomedical characteristics, there was no contamination of the implant by harmful chemical elements. 3D Printing was effective in making the biomodel, enabling pre-operative planning and improving physician-patient communication. Current results indicate that ISF is a process that can be used to obtain custom-made implants.
