Effect of gait speed on muscle activity patterns and magnitude during stance
- Andreia Sousa; João Manuel R. S. Tavares
Purpose: This study aims to assess the influence of gait speed (manipulated through cadence) on muscle activity patterns and activation degree during stance. Methods: Thirty-five healthy individuals participated in this study. Surface electromyographic activity from the gastrocnemius medialis (GM), gluteus maximus (GMax), biceps femoris (BF) and rectus femoris (RF) was acquired with subjects walking at three different speeds. Results: Speed influenced: (1) relative motor activity patterns at heel strike, midstance-propulsion transition and propulsion; (2) the activity level of RF, GMax, GM and BF, in decreasing order, with higher activity at the fastest and slowest speeds. Conclusions: In general, muscle activity...

Uso de técnicas de paralelização em GPGPU e Multirresolução para a Suavização de Imagem
- Carlos ASJ Gulo; Antonio C. Sementille; Alex F. de Araujo; João Manuel R. S. Tavares
Around the world, a lot of researchers have been developed unnumbered contributions to the image processing area, among them, methods have been proposed to reduce the required time to processing large images or achieve real time processing. In this work, it is combined GPGPU parallelization and multiresolution techniques to reducing the processing time required to removing multiplicative noise in images. The experiments have revealed very promising results regarding the achieved computacional speedup.

Human Motion Analysis and Simulation Tools
- João Ferreira Nunes; Pedro Miguel Moreira; João Manuel R. S. Tavares
Motion analysis is currently an active research topic in Computational Vision, Computer Graphics, Machine Learning and Biomechanics mainly due to its applicability into a wide spectrum of relevant applications in many areas. This work intends to present a detailed, broad and up to date survey on motion and/or simulation analysis software packages that have been developed both by the scientific community and commercial entities, to be used in the field of biomechanics. The main contribution of this study, beyond the comprehensive listing of motion analysis tools, is the presentation of an effective framework to classify and compare motion simulation and...

SIARD Archive Browser
- Arif Ur Rahman; Gabriel David; Cristina Ribeiro
SIARD Suite enables us to preserve a relational database in an open format. It migrates a relational database to SIARD format and preserves technical and contextual metadata along with the primary data ensuring long term accessibility.
This paper introduces a web application, the SIARD Archive Browser, which allows operations on the archive such as searching for a specific record, counting records in a table containing a keyword, sorting by a column and making joins. In many use cases, the application avoids the need to load a preserved database to a DBMS.

Desired features for a novel stent-graft
- Isa C.T. Santos; Luís A. Rocha; João Manuel R.S. Tavares
Abdominal aortic aneurysms are indolent but deadly. Among the current treatments is endovascular aneurysm repair, a minimally invasive procedure that resorts to a stent-graft to shield the aortic wall from blood pressure. Although this procedure allowed more patients to be treated and offers several other advantages, complications still occur and there is a need for a more efficient stent-graft. Here, the early steps performed in the development of a novel stent-graft are described, and desired features for an ‘ideal’ device are pointed out. The implementation of these characteristics will lead to a more efficient medical device.

Surface electromyographic amplitude normalization methods: A review
- Andreia S. P. Sousa; João Manuel R. S. Tavares
The electromyogram is the summation of the motor unit action potentials occurring during contraction measured at a given electrode location. The voltage potential of the surface electromyographic signal detected by electrodes strongly depends on several factors, varying between individuals and also over time within an individual. Thus, the amplitude of the EMG signal itself is not useful in group comparisons, or to follow events over a long period of time. The fact that the recorded electromyographic amplitude is never absolute is mainly because impedance varies between the active muscle fibers and electrodes and its value is unknown. The EMG signal...
