Design gráfico : análise da relação com a performance da micro e pequena empresa

O design possui um papel central nos negócios, participando de forma crucial no intercambio cultural e econômico da sociedade. Uma das competências do profissional de design gráfico é o desenvolvimento da Identidade Visual Corporativa (IVC). Ela tem como função definir visualmente o perfil de uma empresa, configurando-se, assim, como um composto mercadológico de fundamental importância para diferenciação das organizações, possuindo um importante papel para o crescimento das micro e pequenas empresas (MPEs). O objetivo desta pesquisa é verificar de que forma os gestores de MPEs percebem a atuação do design gráfico sobre a performance do seu negócio, avaliada a partir da sua experiência com a IVC desenvolvida por um profissional de design e aplicada pela empresa em suas atividades. A pesquisa é aplicada, em relação a sua finalidade, e exploratória, quanto ao seu objetivo. Sua condução se deu a partir de pesquisa bibliográfica, entrevista semiestruturada com os gestores das MPEs investigadas e pesquisa documental em materiais fornecidos pelos sujeitos da pesquisa, realizando-se, desta forma, uma triangulação metodológica a fim de contribuir para o exame do fenômeno. Como estratégia de investigação foi utilizado o estudo de casos múltiplos, realizado com 7 (sete) MPEs que haviam incorporado sua IVC há pelo menos 2 (dois) anos, dos setores de comércio e serviço, localizadas nos municípios de Vitória, Vila Velha, Serra ou Cariacica. Os dados coletados foram analisados por meio da Análise de Conteúdo, com base nas etapas descritas por Bardin (1977) e Laville (1999), distribuindo as unidades de análise (frases e parágrafos) nas categorias desenvolvidas: Motivação, Integração da IVC, Gestão da IVC, Relevância da IVC, IVC e Performance e Expressão Visual. A análise utilizou a abordagem quantitativa, realizada por meio da técnica de percentagem, e qualitativa, com maior ênfase na última, onde foram analisadas as categorias e seus elementos, assim como as relações entre elas, buscando extrair os significados construídos. Desta forma, foi possível verificar que a maior parte dos gestores das MPEs investigadas identificam que o design gráfico, por meio da IVC, contribui de forma positiva para a performance do seu negócio, proporcionando diferentes tipos de benefícios, dentre os mais citados foram: Identificação/Reconhecimento, Fortalecimento (solidez, estabilidade, profissionalismo), Novos Clientes, Imagem, Receptividade, Agregação de Valor para a Marca e Diferenciação.

Towards the design of efficient nonbeacon-enabled ZigBee networks

This paper presents experimental results of the communication performance evaluation of a prototype ZigBee-based patient monitoring system commissioned in an in-patient floor of a Portuguese hospital (HPG – Hospital Privado de Guimar~aes). Besides, it revisits relevant problems that affect the performance of nonbeacon-enabled ZigBee networks. Initially, the presence of hidden-nodes and the impact of sensor node mobility are discussed. It was observed, for instance, that the message delivery ratio in a star network consisting of six wireless electrocardiogram sensor devices may decrease from 100% when no hidden-nodes are present to 83.96% when half of the sensor devices are unable to detect the transmissions made by the other half. An additional aspect which affects the communication reliability is a deadlock condition that can occur if routers are unable to process incoming packets during the backoff part of the CSMA-CA mechanism. A simple approach to increase the message delivery ratio in this case is proposed and its effectiveness is verified. The discussion and results presented in this paper aim to contribute to the design of efficient networks,and are valid to other scenarios and environments rather than hospitals.

Accessing movies based on emotional impact

Emotions play a central role in our daily lives, influencing the way we think and act, our health and sense of well-being, and films are by excellence the form of art that exploits our affective, perceptual and intellectual activity, holding the potential for a significant impact. Video is becoming a dominant and pervasive medium, and online video a growing entertainment activity on the web and iTV, mainly due to technological developments and the trends for media convergence. In addition, the improvement of new techniques for gathering emotional information about videos, both through content analysis or user implicit feedback through user physiological signals complemented in manual labeling from users, is revealing new ways for exploring emotional information in videos, films or TV series, and brings out new perspectives to enrich and personalize video access. In this work, we reflect on the power that emotions have in our lives, on the emotional impact of movies, and on how to address this emotional dimension in the way we classify and access movies, by exploring and evaluating the design of iFelt in its different ways to classify, access, browse and visualize movies based on their emotional impac

Contribution towards a reflection about methodological strategies in design education and the function of drawing in design

This work presents a reflection on Design education and specifically on the role of Drawing in this area. As a subject, Design has expanded its field of action expanding into new areas such as Experience Design or Service Design. It became necessary for the designer to have more than an education based on technological knowledge or know-how. Many authors like Meredith Davis, Don Norman or Jamie Hobson point out the urgency to review the curricula of Design courses because nowadays “… design is more than appearance, design is about interaction, about strategy and about services. Designers change social behavior” (Norman 2011). When shifting from a product-centered design to a person-centered design (in a structure, a service or in a relationship) what should the function of drawing in a design course be? What should its curriculum be? Our work methodology will be to confront today’s perspectives on design theory and practice in an attempt to add to the discussion on the methodological strategies in design teaching in the contemporary context.

Automatic segmentation and 3D feature extraction of protein aggregates in Caenorhabditis Elegans

In the last years, it has become increasingly clear that neurodegenerative diseases involve protein aggregation, a process often used as disease progression readout and to develop therapeutic strategies. This work presents an image processing tool to automatic segment, classify and quantify these aggregates and the whole 3D body of the nematode Caenorhabditis Elegans. A total of 150 data set images, containing different slices, were captured with a confocal microscope from animals of distinct genetic conditions. Because of the animals’ transparency, most of the slices pixels appeared dark, hampering their body volume direct reconstruction. Therefore, for each data set, all slices were stacked in one single 2D image in order to determine a volume approximation. The gradient of this image was input to an anisotropic diffusion algorithm that uses the Tukey’s biweight as edge-stopping function. The image histogram median of this outcome was used to dynamically determine a thresholding level, which allows the determination of a smoothed exterior contour of the worm and the medial axis of the worm body from thinning its skeleton. Based on this exterior contour diameter and the medial animal axis, random 3D points were then calculated to produce a volume mesh approximation. The protein aggregations were subsequently segmented based on an iso-value and blended with the resulting volume mesh. The results obtained were consistent with qualitative observations in literature, allowing non-biased, reliable and high throughput protein aggregates quantification. This may lead to a significant improvement on neurodegenerative diseases treatment planning and interventions prevention

Neural Electrode Array Based on Aluminum: Fabrication and Characterization

A unique neural electrode design is proposed with 3 mm long shafts made from an aluminum-based substrate. The electrode is composed by 100 individualized shafts in a 10 × 10 matrix, in which each aluminum shafts are precisely machined via dicing-saw cutting programs. The result is a bulk structure of aluminum with 65 ° angle sharp tips. Each electrode tip is covered by an iridium oxide thin film layer (ionic transducer) via pulsed sputtering, that provides a stable and a reversible behavior for recording/stimulation purposes, a 40 mC/cm2 charge capacity and a 145 Ω impedance in a wide frequency range of interest (10 Hz-100 kHz). Because of the non-biocompatibility issue that characterizes aluminum, an anodization process is performed that forms an aluminum oxide layer around the aluminum substrate. The result is a passivation layer fully biocompatible that furthermore, enhances the mechanical properties by increasing the robustness of the electrode. For a successful electrode insertion, a 1.1 N load is required. The resultant electrode is a feasible alternative to silicon-based electrode solutions, avoiding the complexity of its fabrication methods and limitations, and increasing the electrode performance.

Improving FEM crash simulation accuracy through local thickness estimation based on CAD data

In this paper, we present a method for estimating local thickness distribution in nite element models, applied to injection molded and cast engineering parts. This method features considerable improved performance compared to two previously proposed approaches, and has been validated against thickness measured by di erent human operators. We also demonstrate that the use of this method for assigning a distribution of local thickness in FEM crash simulations results in a much more accurate prediction of the real part performance, thus increasing the bene ts of computer simulations in engineering design by enabling zero-prototyping and thus reducing product development costs. The simulation results have been compared to experimental tests, evidencing the advantage of the proposed method. Thus, the proposed approach to consider local thickness distribution in FEM crash simulations has high potential on the product development process of complex and highly demanding injection molded and casted parts and is currently being used by Ford Motor Company.

Teaching drawing: an interdisciplinary pedagogical experience in a graphic design course

Various authors have written about the importance of drawing in design methodology. Their general conclusion points drawing as an essential tool for design research, as it allows investigation of several alternative solutions in design process (Cross, 2007). The recent profound changes in design nature (Norman, 2011), justify a discussion on the purpose of drawing in design courses. As a consequence of this new reality, the educational institutions face the challenge of the definition of their curricular structures and teaching methodologies. Among others, concepts such as collaboration and multidisciplinary design approaches have been discussed as strategies for design education (Heller and Talarico, 2011, pp. 82-85). In this context, and using our teaching activity experience in Drawing and Design areas, the authors discuss:  how can drawing methods be included in the current design teaching?  can drawing be considered as an interdisciplinary approach?  what contributions can these methodologies provide to the educational/learning process? Based on these concerns, we developed an interdisciplinary project in the Graphic Design Course with two curricular units: Drawing 1 and Aesthetic and Design Theory 1. In this article the authors present the aims and process developed, and discuss the outcomes of this pedagogical experience.

An Electromagnetic Tracker System for the design of a dental superstructure

Nowadays, different techniques are available for manufacturing full-arch implant-supported prosthesis, many of them based on an impression procedure. Nevertheless, the long-term success of the prosthesis is highly influenced by the accuracy during such process, being affected by factors such as the impression material, implant position, angulation and depth. This paper investigates the feasibility of a 3D electromagnetic motion tracking system as an acquisition method for modeling such prosthesis. To this extent, we propose an implant acquisition method at the patient mouth, using a specific prototyped tool coupled with a tracker sensor, and a set of calibration procedures (for distortion correction and tool calibration), that ultimately obtains combined measurements of the implant’s position and angulation, and eliminating the use of any impression material. However, in the particular case of the evaluated tracking system, the order of magnitude of the obtained errors invalidates its use for this specific application.

Electromagnetic tracker feasibility in the design of a dental superstructure for edentulous patients

The success of the osseointegration concept and the Brånemark protocol is highly associated to the accuracy in the production of an implant-supported prosthesis. One of most critical steps for long-term success of these prosthesis is the accuracy obtained during the impression procedure, which is affected by factors such as the impression material, implant position, angulation and depth. This paper investigates the feasibility of 3D electromagnetic motion tracking systems as an acquisition method for modeling full-arch implant-supported prosthesis. To this extent, we propose an implant acquisition method at the patient mouth and a calibration procedure, based on a 3D electromagnetic tracker that obtains combined measurements of implant’s position and angulation, eliminating the use of any impression material. Three calibration algorithms (namely linear interpolation, higher-order polynomial and Hardy multiquadric) were tested to compensate for the electromagnetic tracker distortions introduced by the presence of nearby metals. Moreover, implants from different suppliers were also tested to study its impact on tracking accuracy. The calibration methodology and the algorithms employed proved to implement a suitable strategy for the evaluation of novel dental impression techniques. However, in the particular case of the evaluated electromagnetic tracking system, the order of magnitude of the obtained errors invalidates its use for the full-arch modeling of implant-supported prosthesis.

A supervised versus home-based program effects on liver transplanted familial amyloidotic polyneuropathy patients: walking, fatigue and quality of life

Purpose: To evaluate the effects of a six months exercise training program on walking capacity, fatigue and health related quality of life (HRQL). Relevance: Familial amyloidotic polyneuropathy disease (FAP) is an autossomic neurodegenerative disease, related with systemic deposition of amyloidal fibre mainly on peripheral nervous system and mainly produced in the liver. FAP often results in severe functional limitations. Liver transplantation is used as the only therapy so far, that stop the progression of some aspects of this disease. Transplantation requires aggressive medication which impairs muscle metabolism and associated to surgery process and previous possible functional impairments, could lead to serious deconditioning. Reports of fatigue are common feature in transplanted patients. The effect of supervised or home-based exercise training programs in FAP patients after a liver transplant (FAPTX) is currently unknown.

Optimal design of piezolaminated structures using B-spline strip finite element models

A package of B-spline finite strip models is developed for the linear analysis of piezolaminated plates and shells. This package is associated to a global optimization technique in order to enhance the performance of these types of structures, subjected to various types of objective functions and/or constraints, with discrete and continuous design variables. The models considered are based on a higher-order displacement field and one can apply them to the static, free vibration and buckling analyses of laminated adaptive structures with arbitrary lay-ups, loading and boundary conditions. Genetic algorithms, with either binary or floating point encoding of design variables, were considered to find optimal locations of piezoelectric actuators as well as to determine the best voltages applied to them in order to obtain a desired structure shape. These models provide an overall economy of computing effort for static and vibration problems.

SIAT:sistema de informações e alertas de trânsito

A evolução tecnológica e das sociedades permitiu que, hoje em dia, uma boa parte da população tenha acesso a dispositivos móveis com funcionalidades avançadas. Com este tipo de dispositivos, temos acesso a inúmeras fontes de informação em tempo-real, mas esta característica ainda não é, hoje em dia, aproveitada na sua totalidade. Este projecto tenta tirar partido desta realidade para, utilizando os diversos dispositivos móveis, criar uma rede de troca de informações de trânsito. O utilizador apenas necessita de servir-se do seu dispositivo móvel para, automaticamente, obter as mais recentes informações de trânsito enquanto, paralelamente, partilha com os outros utilizadores a sua informação. Apesar de existirem outras alternativas no mercado, com soluções que permitem usufruir do mesmo tipo de funcionalidades, nenhuma utiliza este tipo de dispositivos (GPS’s convencionais, por exemplo). Um dos requisitos necessário na implementação deste projecto é uma solução de geocoding. Após terem sido testadas várias soluções, nenhuma cumpria, na totalidade, os requisitos deste projecto, o que originou o desenvolvimento de uma nova solução que cumpre esses requisitos. A solução é, toda ela, muito modular, formada por vários componentes, cada um com responsabilidades bem identificadas. A arquitectura desta solução baseia-se nos padrões de desenvolvimento de uma Service Oriented Architecture. Todos os componentes disponibilizam as suas operações através de web services, e a sua descoberta recorre ao protocolo WS-Discovery. Estes vários componentes podem ser divididos em duas categorias: os do núcleo, responsáveis por criar e oferecer as funcionalidades requisitadas neste projecto e os módulos externos, nos quais se incluem as aplicações que apresentam as funcionalidades ao utilizador. Foram criadas duas formas de consumir a informação oferecida pelo serviço SIAT: a aplicação móvel e um website. No âmbito dos dispositivos móveis, foi desenvolvida uma aplicação para o sistema operativo Windows Phone 7.
