- The factory layout is frequently planned in virtual environments, based on the experience of software tool users. This planning process is cumbersome and iterative to collect the necessary information, with a high risk of faulty inputs and updates. The digital twin concept has been introduced in order to speed up information sharing within a company; it relies on connectivity. However, the concept is often misunderstood as just a 3D model of a virtual object, not including connectivity. The aim of this paper is to present an extended virtual and physical engineering communication framework including four concepts: digital model, digital pre-runner, digital shadow, and digital twin. The four concepts are demonstrated and described in order to facilitate understanding how data exchange between virtual and physical objects can work in the future and having up-to date virtual environments enables simulating, analysing, and improving on more realistic and accurate datasets.

Ingår i: IEEE Transactions on Industrial Informatics. - : Institute of Electrical and Electronics Engineers (IEEE). - 1551-3203 .- 1941-0050. ; 18:11, s. 7998-8006

- The new Industry 4.0 standard has offered many advantages to the industries improving their production rate since it evaluates novel cutting-edge technologies like Artificial Intelligence, Machine Learning, Cyber-Physical Systems, and Internet of Things to automate manufacturing processes so as to minimize time and economical costs while improving the quality of products. However, this rapid industrial transition carries risks in terms of security and privacy issues that arise. In this paper, we propose a novel secure network model to enhance network security and employees privacy in the Edge-enabled Industrial Internet of Things. Experimental results demonstrate encouraging performance rates in terms of accuracy, precision, recall, fall-out, F-measure, and Matthews correlation coefficient against known and unknown bot attacks.

- This paper discusses the efforts carried out related to the design and development of a web-based framework that allows designing, deploying and executing mobile data collecting applications. Furthermore, it also allows analyzing and presenting the data that is generated during the mentioned process. The fact that the framework is completely web-based provides a platform independent execution of the mobile application on any mobile device with a web-browser. As a result that the whole life-cycle of creating, executing and discussing a mobile learning activity is implemented in pure web-based manner separates this work from similar efforts. In the course of this work, the current state of development of two of the components, the authoring tool and the mobile application is presented. This framework was introduced to teachers in an activity to follow up an initial study. On the basis of a workshop with teachers, we performed an explorative study regarding the technology acceptance and usability of two components of the proposed framework. The results are discussed and analyzed in this paper.

- In this chapter, we review and summarize different methods for the evaluation of CSEMPs. The main categories of evaluation methods are (1) comparisons with measurements from real performances, (2) listening experiments, and (3) production experiments. Listening experiments can be of different types. For example, in some experiments, subjects may be asked to rate a particular expressive characteristic (such as the emotion conveyed or the overall expression) or to rate the effect of a particular acoustic cue. In production experiments, subjects actively manipulate system parameters to achieve a target performance. Measures for estimating the difference between performances are discussed in relation to the objectives of the model and the objectives of the evaluation. There will be also a section with a presentation and discussion of the Rencon (Performance Rendering Contest). Rencon is a contest for comparing the expressive musical performances of the same score generated by different CSEMPs. Practical examples from previous works are presented, commented on, and analysed.

Expressive sonification of footstep sounds
- 2010

Ingår i: Proceedings of ISon 2010. - Stockholm, Sweden : KTH Royal Institute of Technology. ; , s. 51-54
-
Konferensbidrag (refereegranskat)abstract
- In this study we present the evaluation of a model for the interactive sonification of footsteps. The sonification is achieved by means of specially designed sensored-shoes which control the expressive parameters of novel sound synthesis models capable of reproducing continuous auditory feedback for walking. In a previousstudy, sounds corresponding to different grounds were associated to different emotions and gender. In this study, we used an interactive sonification actuated by the sensored-shoes for providing auditory feedback to walkers. In an experiment we asked subjects to walk (using the sensored-shoes) with four different emotional intentions (happy, sad, aggressive, tender) and for each emotion we manipulated the ground texture sound four times (wood panels, linoleum, muddy ground, and iced snow). Preliminary results show that walkers used a more active walking style (faster pace) when the sound of the walking surface was characterized by an higher spectral centroid (e.g. iced snow), and a less active style (slower pace) when the spectral centroid was low (e.g. muddy ground). Harder texture sounds lead to more aggressive walking patters while softer ones to more tender and sad walking styles.

Exploration and evaluation of a system for interactive sonification of elite rowing

- In recent years, many solutions based on interactive sonification have been introduced for enhancing sport training. Few of them have been assessed in terms of efficiency or design. In a previous study, we performed a quantitative evaluation of four models for the sonification of elite rowing in a non-interactive context. For the present article, we conducted on-water experiments to investigate the effects of some of these models on two kinematic quantities: stroke rate value and fluctuations in boat velocity. To this end, elite rowers interacted with discrete and continuous auditory displays in two experiments. A method for computing an average rowing cycle is introduced, together with a measure of velocity fluctuations. Participants answered to questionnaires and interviews to assess the degree of acceptance of the different models and to reveal common trends and individual preferences. No significant effect of sonification could be determined in either of the two experiments. The measure of velocity fluctuations was found to depend linearly on stroke rate. Participants provided feedback about their aesthetic preferences and functional needs during interviews, allowing us to improve the models for future experiments to be conducted over longer periods.

- The art of circus is a vibrant and competitive culture that embraces new tools and technology. In this paper, a series of exploratory design processes resulting in proofs of concepts are presented, showing strategies for effective use of three different modes of sonic interaction in contemporary circus. Each design process is based on participatory studio work, involving professional circus artists. All of the proofs of concepts have been evaluated, both with studio studies and public circus performances, taking the work beyond theoretical laboratory projects and properly engaging the practice and culture of contemporary circus.The first exploration uses a contortionist’s extreme bodily manipulation as inspiration for sonic manipulations in an accompanying piece of music. The second exploration uses electric amplification of acoustic sounds as a transformative enhancement of existing elements of circus performance. Finally, a sensor based system of real-time sonification of body gestures is explored and ideas from the sonification of dance are translated into the realm of circus.
