Analysis of walking patterns can play an important role in the diagnosis of musculoskeletal disorder and detecting anomalies in walking gaits. In this work, we introduce a systematic approach to detect person's walking patterns. A flexible resistive pressure sensor, developed from electro-conductive textile fabric, is non-intrusively integrated in...

There is an increasing worldwide demand for people educated into science and technology. Unfortunately, girls and underprivileged students are often underrepresented in Science, Technology, Engineering and Mathematics (STEM) education programs. We believe that by inclusion of art in these programs, educational activities might become more attractiv...

Building a robot from scratch in an educational context can be a challenging prospect. While a multitude of projects exist that simplify the electronics and software aspects of a robot, the same cannot be said for construction systems for robotics. In this paper, we present our efforts to create a low-cost do-it-yourself construction system for sma...

Full-text available
Centrifuges have been used in many ways to determine permeabilities, as they can significantly shorten testing times in low-permeable soils. Typically equilibrium profiles, inflow-outflow measurements, or direct measurements from inside the sample - like from tensiometers or radioactive decay - are used. Recently, weight measurements of the sample...
Article
Several studies, both theoretical and experimental, have already proven that mathematical modelling of wastewater treatment plants (WWTP) is an elegant and cost-effective tool to study and to optimise these treatment processes. In most cases, interpretation of the simulation results is done on ad hoc complex databases based on so-called expert know...

This paper describes the current status of Ono, an open source social robot that can be made using DIY tools and techniques. We believe that low-cost open source social robots provide advantages that current high-end robots do not have: they are well suited for large-scale studies and they are accessible for students and hobbyists. We describe the...
Article
Designers and engineers in practice can rely on a comprehensive assortment of physical connections such as bolts, adhesives, and snap joints to design a product. However, future materials, processes, and technologies lead to other requirements. Designers must be creative to find new solutions that meet the new requirements. The Design to Connect me...
Conference Paper
Full-text available
One of the major obstacles in the study of HRI (human-robot interaction) with social robots is the lack of multiple identical robots that allow testing with large user groups. Often, the price of these robots prohibits using more than a handful. A lot of the commercial robots do not possess all the necessary features to perform specific HRI experim...

Retrospective study. To determine the short-term clinical succesrate of the M6-C cervical disc prosthesis (Spinal Kinetics, Sunnyvale, CA, USA) in primary and secundary surgery. Cervical Disc Arthroplasty (CDA) provides an alternative to Anterior Cervical Decompression and Fusion (ACDF) for the treatment of spondylotic radiculo- or myelopathy. The...
Conference Paper
Full-text available
This paper aims to give an overview of technologies that can be used to implement robotics within an educational context. We discuss complete robotics systems as well as projects that implement only certain elements of a robotics system, such as electronics, hardware, or software. We believe that Maker Movement and DIY trends offers many new opport...

A survey was set-up using a web-application supplemented with a print-out questionnaire to gather knowledge on consumption patterns and consumer behaviour in the storage and preparation of poultry meat, in particular poultry meat preparations for Belgian adults. In total 1618 respondents were reached. The survey included questions on risk factors a...

Among spinning objects, the tippe top exhibits one of the most bizarre and counterintuitive behaviours. The commercially available tippe tops basically consist of a section of a sphere with a rod. After spinning on its rounded body, the top flips over and continues spinning on the stem. It is the friction with the bottom surface and the position of...

In this study the physico-chemical composition reported on the label of 49 bottled still waters, 22 bottled sparkling waters and 13 tap waters were used to carry out a characterization study by means of multivariate pattern recognition methods such as principal components analysis (PCA) and discriminant analysis. Also, analysis of variance was used...
Article
We study quasi-periodic tori under a normal-internal resonance, possibly with multiple eigenvalues. Two non-degeneracy conditions play a role. The first of these generalizes invertibility of the Floquet matrix and prevents drift of the lower dimensional torus. The second condition involves a Kolmogorov-like variation of the internal frequencies and...

We consider a tippe top modeled as an eccentric sphere, spinning on a horizontal table and subject to a sliding friction. Ignoring translational effects, we show that the system is reducible using a Routhian reduction technique. The reduced system is a two dimensional system of second order differential equations, that allows an elegant and compact...
Article
We present a generalized Lyapunov Schmidt (LS) reduction scheme for diffeomorphisms on a finite dimensional real vector space V which transform tinder real one-dimensional characters X of an arbitrary compact group with linear action on V. Moreover we prove a normal form theorem, such that the normal form still has the desirable transformation prop...
Article
We investigate the bifurcation of q-periodic points from a fixed point of a 2-parameter family of n-dimensional reversible diffeomorphisms (n ≥ 4). The focus is on the codimension 2 non-semisimple 1:1 resonance case, that is, when the linearization at the fixed point has a pair of double eigenvalues on the unit circle, exp ( ± 2iπp/q) (with gcd(p,...
Article
Full-text available
Kolmogorov-Arnol’d-Moser theory classically was mainly developed for conservative systems, establishing persistence results for quasi-periodic invariant tori in nearly integrable systems. In this survey we focus on dissipative systems, where similar results hold. In non-conservative settings often parameters are needed for the persistence of invari...

We present a generalized Lyapunov Schmidt reduction scheme for diffeomorphisms living on a finite dimensional real vector space V which transform under real one dimensional characters of an arbitrary compact group with linear action V. Moreover we prove a normal form theorem, such that the normal form still has the desirable transformation properti...
Article
Full-text available
In this paper we survey a general Liapunov-Schmidt type of reduc- tion for the study of the bifurcation of periodic points from a symmetric fixed point in families of reversible diffeomorphisms. The approach is strongly in- terwoven with normal form theory for reversible mappings, and also addresses the stability problem for the bifurcating periodi...
Article
We introduce a general reduction method for the study of periodic points near a fixed point in a family of reversible diffeomorphisms. We impose no restrictions on the linearization at the fixed point except invertibility, allowing higher multiplicities. It is shown that the problem reduces to a similar problem for a reduced family of diffeomorphis...

Deticated to Gerry Ladas on the occasion of his sixtieth birthday. We give a eneral reduction method for the study of the bifurcation peridoic points from a fixed point of a symplectic diffeomorphism. For each fixedperiod q the recutcion leads to a problem similar to the original one. but ona smaller space and having an additionak -symmetry. In the...
Article
We survey some resent results on the bifurcation of periodic points from a fixed point in parametrized families of reversible or symplectic diffeomorphisms; such bifurcation problems arise for example when studying subharmonic branching in reversible or Hamiltonian systems. For the sake of brevity we mainly concentrate on the reversible case. For g...

3D body scanning will be employed to gain better insight in anthropometric differences between average population and two groups of athletes (rowers and cyclists) and a methodology for translating this information effectively to the garment production will be worked out. Sport-specific dynamic postures will be also investigated. Comfort at material and garment level will be investigated including influence of design, material, fit and dynamic posture on body-sportswear interface pressure.
