The effectiveness of a mobile high-frequency chest wall oscillation (HFCWO) device for airway clearance University of Antwerp
Introduction High-frequency chest wall oscillation (HFCWO) is a commonly prescribed airway clearance technique (ACT) for patients whose ability to expectorate sputum is compromised. This study aimed to assess the effectiveness of a newly developed mobile ACT device (mHFCWO-The Monarch Airway Clearance System) in patients with cystic fibrosis (CF). A standard nonmobile HFCWO device (sHFCWO) was used as a comparator. Methodology This was a ...
Three sources, three receivers, six degrees of freedom University of Antwerp
Motion capture systems have become a common utility in a wide variety of fields and rely on various underlying principles to estimate the pose of one or multiple mobile objects. The most popular applications for pose estimation systems can be found in the entertainment sector where it is used for computer animation purposes or in sports for performance measurements. These systems present millimeter accuracy but also come with a high cost. We ...
Angle of arrival estimation for low power and long range communication networks University of Antwerp
Over a decade ago, Low Power Wide Area Networks (LPWAN) emerged to meet the new communication requirements demanded by the Internet of Things (IoT) revolution. Therefore, seemingly futuristic ideas that are based on the IoT concept (e.g. smart cities, smart highways, smart farms, etc) appear ever more plausible. This communication revolution can be attributed to the LPWAN’s capability of establishing long range communication links (up to several ...
Interoperability of MAS DSMLs via horizontal model transformations University of Antwerp
In this paper, we present our approach which aims at improving the mechanism of constructing language semantics over the interoperability of domain-specific modeling languages (DSMLs) developed for Multi-agent Systems (MAS) and hence providing a more efficient way of extension for the executability of modeled agent systems on various underlying agent platforms. Differentiating from the existing MAS DSML studies, our proposal is based on ...
Calibration of deployment simulation models University of Antwerp
In embedded systems development, software engineers increasingly rely on modelling and simulation to produce optimal design solutions. A bottleneck in the Modelling and Simulation Based Design (MSBD) process is model calibration. Setting up experiments to estimate parameter values such that the model accurately reflects real-world system structure and behaviour is technically complex and labour intensive. Parameters to be estimated are for ...
A simplified model to assess the thermal performance of pavement solar collectors University of Antwerp
The assessment of thermal performance and efficiency of the Pavement Solar Collector (PSC) systems is essential in designing such systems. In this paper, a simplified simulation model is developed to predict PSC's performance at the design stage. Due to its simplicity, accuracy, and extremely quick simulation run-time, the model output can be linked with other thermal models and renewable heat sources to apply real-time changes in the PSC ...
Towards a Formal Specification of Multi-Paradigm Modelling University of Antwerp
The notion of a programming paradigm is used to classify programming languages and their accompanying workflows based on their salient features. Similarly, the notion of a modelling paradigm can be used to characterise the plethora of modelling approaches used to engineer complex Cyber-Physical Systems (CPS). Modelling paradigms encompass formalisms, abstractions, workflows and supporting tool(chain)s. A precise definition of this modelling ...
A three-year feedback study of a remote laboratory used in control engineering studies University of Antwerp KU Leuven Ghent University
This paper discusses the results of a feedback study for a remote laboratory used in the education of control engineering students. The goal is to show the effectiveness of the remote laboratory on examination results. To provide an overview, the two applications of the remote laboratory are addressed: 1) the Stewart platform, and 2) the quadruple water tank system. Combining both applications allows a broad spectrum of practical examples ...
Online tracking of dynamically time-varying inertia using an enhanced SDFT-based estimation methodology University of Antwerp
The overall motion performance of mechatronic machines depends heavily on proper knowledge of the machine’s characteristics, among which the inertia. Moreover, the inertia of most multi-body mechanisms, for example, reciprocating slider-crank mechanisms, varies as a function of the machine position, thereby challenging optimal control. Nevertheless, the inertia’s variation is sometimes not known accurately enough or changes over time due to, ...
