In this paper we introduce a novel framework for pervasive computing called PICO (Pervasive Information Community Organization). PICO allows distributed computing and communication capabilities at higher and lower levels of abstraction, resulting in a significant improvement in current models of information systems for dynamic applications such as telemedicine, manufacturing, and crisis managem...

This paper introduces a novel zooming interface deploying a pico projector that, instead of a second visual display, leverages audioscapes for contextual information. The technique enhances current flashlight metaphor approaches, supporting flexible usage within the domain of spatial augmented reality to focus on object or environment-related details. Within a user study we focused on quantifyi...

MOTIVATION There have been several studies on the micro-inversions between human and chimpanzee, but there are large discrepancies among their results. Furthermore, all of them rely on alignment procedures or existing alignment results to identify inversions. However, the core alignment procedures do not take very small inversions into consideration. Therefore, their analyses cannot find invers...

In this paper we describe our participation to the CLEF eHealth 2017 Technology Assisted Reviews track (TAR). This track aims to evaluate and advance search technologies aimed at supporting the creation of biomedical systematic reviews. In this context, the track explores the task of screening prioritisation: the ranking of studies to be screened for inclusion in a systematic review. Our soluti...

This article explores the main tradeoffs in design of subthreshold source-couple logic (STSCL) circuits. It is shown analytically that the bias current of each STSCL gate can be reduced to few pico-amperes with a reliable logic operation. Measurements on different digital building blocks are provided to validate the main concepts presented in this paper. Implemented in conventional 0.18μm CMOS ...

Modern miniaturization technologies enable the realization of very small satellites at masses below 1kg, nevertheless limited attitude determination and actuator performances raise challenging control problems. Specific attitude determination aspects discussed at the example of UWE (University of Wuerzburg Experimental satellite), a standardized pico-satellite platform related to technology dem...

To clarify the property of tritium removal from carbon codeposition by using pulsed-laser induced desorption, hydrogen removal from co-deposits on JT-60 divertor tile using a fourth-harmonic emission (266 nm) of a nano-sec Nd:YAG laser was demonstrated. The threshold laser fluence for ablation was ~ 0.3 J/cm, which was slightly higher compared to that of the pico-sec laser irradiation. The ener...

O comportamento eletroquímico da vitamina E em meio hidro-alcoólico foi estudado na faixa de pH 3,1-12,1 aplicando-se as técnicas voltametria cíclica, eletrólise com potencial controlado e espectroscopias UV-Vis, IR e C RMN. Observou-se que a presença de água tem conseqüências importantes na estabilidade química das espécies geradas eletroquimicamente. Em meio hidro-alcoólico e sobre eletrodos ...

We offer summer projects related to the following topics. For more information on our research in general, check out the group website and recent publications. All topics are suitable for both Bachelor’s and Master’s students, and the summer project can be summarized as a Bachelor’s thesis or a special assignment. Also topics for Master’s theses are available. The projects include design and na...
