How CPR is like Madonna
2012
The purpose of this panel is to provide a formal forum and opportunity to reflect on the past, discuss the present, and provide direction and inspiration for the future of what we now call Computers and People Research (CPR). To what extent have these early concerns and themes endured? How have they been transformed over five decades of changes in technology, changes in the workplace and global business context, and IT worker demographics? What progress has the CPR community made in addressing these concerns? What new issues has CPR brought forward that were not envisioned by the early CPR pioneers?
Uso de la infografía en la optativa “Alimentación y Dietética” del grado de Medicina
2020
[ES] Como sustitución de la clase magistral, en la sesión dedicada a tratar las características de “dietas occidentales de moda” de la asignatura optativa 34493-Alimentación y Dietética del Grado en Medicina de la Universitat de Valencia, se utilizaron infografías previamente diseñadas por los estudiantes. Con esta iniciativa se pretendía mejorar la participación del alumnado en la asignatura, además de profundizar en la materia, mejorar sus habilidades digitales y de búsqueda y síntesis de información. Esta propuesta fue bien valorada por el estudiantado, que mostró su preferencia por esta forma de trabajar frente a la clase magistral. Además, opinó que la actividad mejoraba su capacidad d…
The influence of innovation stimulus, facilitating factors and support mechanisms on innovation performance in Brazilian small textile firms
2020
The ability of the organisation to develop new products is crucial in rapidly changing business environments, and thus, customer demographics, consumers' expectations and buying behaviour play an important role. Hence, exploring the antecedents of innovation performance becomes more important. This study analyses the relationships among innovation stimulus, facilitating factors and support mechanisms for innovative performance in the textile industry of Santa Catarina, Brazil. The sample included 128 respondents, who were all employees of five small and medium-sized textile firms; data were analysed using structural equation modelling. We found that innovation stimulus, facilitating factors…
Wet Chemical Synthesis and a Combined X-ray and Mössbauer Study of the Formation of FeSb2 Nanoparticles
2011
Understanding how solids form is a challenging task, and few strategies allow for elucidation of reaction pathways that are useful for designing the synthesis of solids. Here, we report a powerful solution-mediated approach for formation of nanocrystals of the thermoelectrically promising FeSb(2) that uses activated metal nanoparticles as precursors. The small particle size of the reactants ensures minimum diffusion paths, low activation barriers, and low reaction temperatures, thereby eliminating solid-solid diffusion as the rate-limiting step in conventional bulk-scale solid-state synthesis. A time- and temperature-dependent study of formation of nanoparticular FeSb(2) by X-ray powder dif…
LightSpMV: Faster CSR-based sparse matrix-vector multiplication on CUDA-enabled GPUs
2015
Compressed sparse row (CSR) is a frequently used format for sparse matrix storage. However, the state-of-the-art CSR-based sparse matrix-vector multiplication (SpMV) implementations on CUDA-enabled GPUs do not exhibit very high efficiency. This has motivated the development of some alternative storage formats for GPU computing. Unfortunately, these alternatives are incompatible with most CPU-centric programs and require dynamic conversion from CSR at runtime, thus incurring significant computational and storage overheads. We present LightSpMV, a novel CUDA-compatible SpMV algorithm using the standard CSR format, which achieves high speed by benefiting from the fine-grained dynamic distribut…
Mixed camera angles viewpoints improve learning medical hand procedure in nurse training
2017
Communication donnée le 31 Août 2017 lors de la session J 10 : Instructional Design, Learning and Instructional TechnologyComprehension of Text and Graphics - C; International audience; Few previous research showed that camera viewpoints differences played a role in learning hand procedures from videos. However, learning videos on hand procedures showing only single viewpoints have been investigated, for example face to face vs. over the shoulder views. Further, the effect of seeing the human model's face and the effect of showing hand actions have also been studied. The results of these research are not always consistent. The goal of the present research was to investigate the effect of mi…
Three-Dimensional Imaging and Display through Integral Photography
2014
Here, we present a review of the proposals and advances in the field of three-dimensional (3D) imaging acquisition and display made in the last century. The most popular techniques are based on the concept of stereoscopy. However, stereoscopy does not provide real 3D experience, and produces discomfort due to the conflict between convergence and accommodation. For this reason, we focus this paper on integral imaging, which is a technique that permits the codification of 3D information in an array of 2D images obtained from different perspectives. When this array of elemental images is placed in front of an array of microlenses, the perspectives are integrated producing 3D images with full p…
Microscopic and macroscopic 3D imaging and display by integral imaging
2011
Integral imaging is a rising 3D imaging technique that can be considered the incoherent version of holography. In integral imaging the multiperspective information of 3D scenes is stored in a 2D picture. Such picture, composed by a set of elemental images, is obtained through a 2D array of microlenses. The elemental-images set can be used for many purposes. One is the display of 3D color scenes to audiences or much more than one person. Other is the 3D display, with full parallax, in personal monitors, like the screen of a smartphone, a tablet, or the monitor used by a surgeon in an endoscopic operation. Other important types of applications are connected with the topographic reconstruction…
Full-parallax immersive 3D display from depth-map cameras
2016
We exploit two different versions of the Kinect to make comparison of three-dimensional (3D) scenes displayed by proposed integral imaging (InI) display system. We attempt to show the difference between each version specifications and capacity. Furthermore, we illustrate our study result with some empirical imaging experiment in which the final result are displayed with full-parallax. Each demonstrated integral images can provide clear comparison results to the observer.
