    Alignment strategies for the entrainment of music and movement rhythms

    Theories of entrainment assume that spontaneous entrainment emerges from dynamic laws that operate via mediators on interactions, whereby entrainment is facilitated if certain conditions are fulfilled. In this study, we show that mediators can be built that affect the entrainment of human locomotion to music. More specifically, we built D-Jogger, a music player that functions as a mediator between music and locomotion rhythms. The D-Jogger makes it possible to manipulate the timing differences between salient moments of the rhythms (beats and footfalls) through the manipulation of the musical period and phase, which affect the condition in which entrainment functions. We conducted several experiments to explore different strategies for manipulating the entrainment of locomotion and music. The results of these experiments showed that spontaneous entrainment can be manipulated, thereby suggesting different strategies on how to embark. The findings furthermore suggest a distinction among different modalities of entrainment: finding the beat (the most difficult part of entrainment), keeping the beat (easier, as a temporal scheme has been established), and being in phase (no entrainment is needed because the music is always adapted to the human rhythm). This study points to a new avenue of research on entrainment and opens new perspectives for the neuroscience of music

    Feature placement algorithms for high-variability applications in cloud environments

    While the use of cloud computing is on the rise, many obstacles to its adoption remain. One of the weaknesses of current cloud offerings is the difficulty of developing highly customizable applications while retaining the increased scalability and lower cost offered by the multi-tenant nature of cloud applications. In this paper we describe a Software Product Line Engineering (SPLE) approach to the modelling and deployment of customizable Software as a Service (SaaS) applications. Afterwards we define a formal feature placement problem to manage these applications, and compare several heuristic approaches to solve the problem. The scalability and performance of the algorithms is investigated in detail. Our experiments show that the heuristics scale and perform well for systems with a reasonable load

    Aesthetic Experience in Virtual Museums: A Postphenomenological Perspective

    This article explores the impact of the digitization of traditional works of art on the aesthetic experience from a philosophical point of view. Presenting and making use of a recent approach in the philosophy of technology, initiated by the American philosopher Don Ihde, called postphenomenology. This hybrid form of phenomenology builds on traditional phenomenology and combines it with a pragmatic approach in order to focus on the mediating roles of technology. Concrete technologies and applications such as screens and virtual museums are the starting point for our examination of the specific character of these digital media, which are then compared with their physical referents. Following Ihde’s arguments, we show that digital image technologies, and digital images themselves, are not merely functional, but shape perceptions and experiences. Although currently the positive effects and opportunities of these new applications are emphasized in the field – for collection management, the democratization and accessibility of art, possibilities to interact and intervene in the image, efficient marketing, etc. – they do have a significant impact on the way in which art is experienced
