We present an open-source software platform that transforms the emotions expressed by speech signals using audio effects like pitch shifting, inflection, vibrato, and filtering. The emotional transformations can be applied to any audio file, but can also run in real-time (with less than 20-millisecond latency), using live input from a microphone. We anticipate that this tool will be useful for ...

Web-based access to health services, health information and personal health records are increasingly offered to patients for enabling a new, more active patient role. However, incorporating such solutions into national health infrastructures poses challenges. In an information infrastructure perspective, the design of such technologies requires two main intertwined activities: designing ‘the ne...

by Kyle Bruce Wheeler Network intrusion detection systems (NIDS) are deployed near network gateways to analyze all traffic entering or leaving the network. The traffic at such locations is frequently transmitted in such volumes and speeds that a commodity computer quickly becomes overwhelmed. NIDS must be able to handle all of the traffic available. The SPANIDS platform addresses this problem w...

We present an open-source software platform that transforms emotional cues expressed by speech signals using audio effects like pitch shifting, inflection, vibrato, and filtering. The emotional transformations can be applied to any audio file, but can also run in real time, using live input from a microphone, with less than 20-ms latency. We anticipate that this tool will be useful for the stud...

Geographic relevance aims to assess the relevance of physical entities (e.g., shops and museums) in geographic space for a mobile user in a given context, thereby shifting the focus from the digital world (the realm of classical information retrieval) to the physical world. We study the elicitation of geographic relevance criteria by means of both a classical survey and an Amazon Mechanical Tur...

For perovskite oxides, ABO3, slight octahedral distortions have close links to functional properties. While perovskite oxide heterostructures offer a good platform for controlling functionalities, atomistic understanding of octahedral distortion at the interface has been a challenge as it requires precise measurements of the oxygen atomic positions. Here we demonstrate an approach to clarify di...

The structure and aim of continuing medical education (CME) is shifting from the passive transmission of knowledge to a competency-based model focused on professional development. Self-directed learning is emerging as the foremost educational method for advancing competency-based CME. In a field marked by the constant expansion of knowledge, self-directed learning allows physicians to tailor th...

Current computational systems are heterogeneous by nature, featuring a combination of CPUs and GPUs. As the latter are becoming an established platform for high-performance computing, the focus is shifting towards the seamless programming of these hybrid systems as a whole. The distinct nature of the architectural and execution models in place raises several challenges, as the best hardware con...

The problem of rising health care costs and the related increased dependency on health insurance coverage has moved to the forefront of the U.S. policy agenda in recent years and was a fundamental component of President Clinton's 1992 campaign platform. However, the President's 1994 health care reform proposal was unsuccessful, and current GOP proposals to cut the rate of growth of Medicare and...

Multi-Processor System on Chip (MPSoC) platforms are becoming increasingly more heterogeneous and are shifting towards a more communication-centric methodology. Net-works on Chip (NoC) have emerged as the design paradigm for scalable on-chip communication architectures. As the system complexity grows, the problem emerges as how to design and instantiate such a NoC-based MPSoC platform in a syst...
