Internet of Things (IoT) provides a thematic umbrellathat allows educators to combine various theoretical aspectsof computer science with substantial problems in everydaylife. As such, building IoT device prototypes has been suggestedby many as a means for teaching computer science and softwareengineering. However, how assessment should be conducted inthese exploratory courses is often left vague,...
Exertion based games have shown significant potential to influence health and well-being positively. Natural locomotion systems have been developed towards this end, however designing appropriate control schemes for such systems are particularly challenging as performance degradation might occur in terms of response time, precision and dexterity in consequence. This could affect the player's sense...
Recent advances in sensor technologies and instrumentation have led to an extraordinary growth of data sources and streaming applications. A wide variety of devices, from smart phones to dedicated sensors, have the capability of collecting and streaming data at unprecedented rates. Typical applications include smart cities & built environments for instance, where sensor-based infrastructures continue...
This paper presents a modelling approach for estimating the density of sealed surface cover within residential areas, using a set of explanatory variables describing the spatial context of each area, its morphological properties and its population density. The model is calibrated and applied on Flanders and the Brussels Capital Region using a 30m sealed surface cover fraction map for 2013, obtained...
Context is a fundamental tool humans use for understanding their environment, and it must be modelled in a way that accounts for the complexity faced in the real world. Current context modelling approaches mostly focus on a priori defined environments, while the majority of human life is in open, and hence complex and unpredictable, environments. We propose a context model where the context is organized...
Software Product Line Engineering is a key approach to construct applications with systematical reuse of architecture, documents and other relevant components. To migrate legacy software into a product line system, it is essential to identify the code segments that should be constructed as features from the source base. However, this could be an error-prone and complicated task, as it involves exploring...
It has been shown in the literature that automatic speech recognition systems can greatly benefit from contextual information [1, 2, 3, 4, 5]. Contextual information can be used to simplify the beam search and improve recognition accuracy. Types of useful contextual information can include the name of the application the user is in, the contents of the user's phone screen, the user's location, a certain...
Recent focus on assistant products has increased the need for extremely flexible speech systems that adapt well to specific users' needs. An important aspect of this is enabling users to make voice commands referencing their own personal data, such as favorite songs, application names, and contacts. Recognition accuracy for common commands such as playing music and sending text messages can be greatly...
This paper describes results from the study case in developing an ontology for the Indonesian medicinal plants. The approach to the new way of developing ontology is taken from the point view of a socio-technical system theory. The case study was conducted after the theoretical model development developed through a qualitative research synthesis which aimed as a proof of concept. We describe a socio-technical...
Population consensus may lead to scenarios of positive feedback in which the momentum toward a consensus could result in outcomes that may not be in the best interests of society—the opinion dynamics that lead to support for a negotiated settlement or peace agreement might similarly lead to mass violence and riots. Given this, additional insight into how consensus might be influenced has broad implications...
Sedentary behaviors such as prolonged occupational and leisure-time sitting are now ubiquitous in modern societies. Sedentary time is positively associated with increased risk of obesity, diabetes, cardiovascular disease, and all-cause mortality. Smartphones can sense the sedentary behaviors performed by their users, as well as the contexts (situations) in which sedentary behaviors occur. In this...
Situated Visualization techniques are visualization techniques that provide a presentation of information within its spatial context. Situated Visualization techniques have several advantages compared to traditional visualization techniques with the biggest advantage being providing the spatial relationship between data and the actual environment. However, Situated Visualization techniques are also...
Research methods education is a topic of growing interest in academic pro-grams. Previously authors reported on KICSS 2015 that learning and studying may present a challenge when trying to apply students' prior knowledge. This study continues addressing the question of whether or not an internal session comprising open discussion and brainstorming followed by asynchronous commenting and ending with...
Verification and validation of UML/OCL models is a crucial task in the design of complex software/hardware systems. The behavior in those models is expressed in terms of operations with pre- and postconditions. These, however, are often not precise enough to describe what may or may not be modified in a transition between two system states. This frame problem is commonly addressed by providing additional...
In this paper we present a technique that takes advantage of detected building façades and OpenStreetMaps data to improve the localization of an autonomous vehicle driving in an urban scenario. The proposed approach leverages images from a stereo rig mounted on the vehicle to produce a mathematical representation of the buildings' façades within the field of view. This representation is matched against...
This paper proposes a topic model-based recommendation system that predicts a user's rating score of a searched media unit for media re-creation service. The purpose of the proposed recommender is to perform a context-aware recommendation of suitable media units for a user's purpose and context. For this purpose, it uses a topic vector based on the metadata of the media to compare the similarity of...
In urban environments the most interesting and effective factors for localization and navigation are landmark buildings. This paper proposes a novel method to detect such buildings that stand out, i.e. would be given the status of 'landmark'. The method works in a fully unsupervised way, i.e. it can be applied to different cities without requiring annotation. First, salient points are detected, based...
(Design decisions for a critical thinking curriculum for Engineering students serves as a point of departure to briefly describe an under-appreciated reason to emphasize critical thinking in Engineering programs. An increasing focus on the role of context, environment and systems in shaping human judgement means that engineers should be especially aware of the propensity for designs and implementations...
This article proposes to implement an idea of "performative eportfolio" into our technical and professional communication class, with a focus on helping students construct their ethos through integrating writing, speaking, and reflection.
Selecting the appropriate parameters for an indoor positioning system may be a difficult task due to the large number of parameter combinations. It is more complex in realistic multi-building multi-floor environments, where severe wrong building and floor errors occur but they are not highlighted in the main evaluation metric. Moreover, a selected parameter configuration, that may seem appropriate...
