Design and construction of buildings is one of the most expensive enterprises. CAD plans in the domain of architecture contain thousands of design fragments (cases) which could be helpful for later use. In FABEL we try to find those fragments which are useful for a problem, to evaluate them and adapt them to the current context. The present approach helps to support a CAD system with case based...
We describe a hierarchical scheme for rapid adaptation of context dependent “skills”. The underlying idea is to first invest some learning effort to specialize the learning system to become a rapid learner for a restricted range of contexts. This is achieved by constructing a “Meta-mapping” that replaces an slow and iterative context adaptation by a “one-shot adaptation”, which is a context-dependent...
The main idea of the presented approach is based on the observation that identical data can be interpreted and used differently in different situations and by different persons. Data is considered individually and according to the actual situation. This phenomena can be interpreted as regarding different aspects. Here, the notion of aspects is applied to cases in the area of Cased Based Reasoning...
Design and construction of buildings is a most expensive enterprise. CAD plans of architects and civil engineers contain thousands of layout fragments (cases) which could be helpful for later use. In FABEL we try to find those fragments which are useful for a problem, to evaluate them and adapt them to the current context. The present approach helps to support a CAD system with case based reasoning...
This paper deals with the retrieval of useful cases in case-based reasoning. It focuses on the questions of what ”useful” could mean and how the search for useful cases can be organized. We present the new search algorithm Fish and Shrink that is able to search quickly through the case base, even if the aspects that define usefulness are spontaneously combined at query time. We compare Fish and Shrink...
Recent studies have suggested a strong association between obstructive sleep apnoea (OSA) and atrial fibrillation (AF). However, the impact of continuous positive airway pressure (CPAP) therapy on reverse atrial remodelling in patients with OSA is poorly understood. We aimed to determine the impact of CPAP therapy on total atrial conduction time measured by PA tissue Doppler imaging (TDI) interval...
The ever rising energy and accordingly cooling demands are a major hurdle for the scalability of today's supercomputers. We are challenged with the need to increase computation performance to cope with the rising complexity of calculations on the one hand and the need to keep the energy/cooling demand stable or in the best case even to reduce it. Recently, one widely discussed way to do this is the...
ArchC is an architecture description language that provides instruction set level simulation and binary tool chain generation. It is based on SystemC and can communicate with other SystemC components using transaction level modeling (TLM). In this article we present an upgrade of ArchC that allows TLM-2.0 usage and makes it available in timed simulations. These extensions enable performance evaluation...
Oxygen and hydrogen evolution reactions in flooded lead-acid batteries during float charging were studied by galvanostatic steady-state polarization and impedance spectroscopy techniques. Given the very low relaxation frequencies of such processes (between 2 and 0.05mHz), impedance measurements needed to be extended to the ultra-low frequency domain. Investigation of their dynamic behavior provided...
