Motion platforms are used to increase the realism of virtual interaction. Unfortunately, their size and weight is proportional to what they actuate. We present haptic turk, a different approach to motion platforms that is light and mobile. The key idea is to replace motors and mechanical components with humans. All haptic turk setups consist of a player who(More)
We propose using spatial gestures not only for input but also for output. Analogous to gesture input, the proposed gesture output moves the user's finger in a gesture, which the user then recognizes. We use our concept in a mobile scenario where a motion path forming a "5" informs users about new emails, or a heart-shaped path serves as a mes- sage from a(More)
Security has recently become a very important concern for entities using IPv6 networks. This is especially true with the recent news reports where governments and companies have admitted to credible cyber attacks against them in which confidential information and the security of data have been compromised. In this paper we will introduce a flexible(More)
BACKGROUND With a frequency of about 90 %, head and neck squamous cell carcinomas (HNSCCs) are the most common malignancies of the upper aerodigestive tract. The cancer stem cell (CSC) hypothesis postulates that CSCs are the dangerous part of the tumor and are relevant to metastasis, invasiveness and resistance to chemotherapy. METHODS Tissue samples(More)
Cost models play an important role for the efficient implementation of software systems. These models can be embedded in operating systems and execution environments to optimize execution at run time. Even though non-uniform memory access (NUMA) architectures are dominating today's server landscape, there is still a lack of parallel cost models that(More)
