AT THE SWISS FEDERAL INSTItute of Technology’s Artificial Intelligence Laboratory, we have developed an approach that combines qualitative reasoning and memory-based reasoning, thereby exploiting their strengths and compensating for their weaknesses. We have applied this approach to two processes: coffee roasting and decaffeination. Both applications used large amounts of data collected from pl...

People usually use qualitative terms to express spatial relations, while current geographic information systems (GISs) all use quantitative approaches to store spatial information. The abilities of current GISs to represent and query spatial information about geographic space are limited.

The assessments of machinability of metal cutting are called "indices" and are derived by comparative research. These indices are the relations of two identical parameters, such as is the allowable cutting speed. The assessments were obtained at a constant tool life of 60 min, at the appropriate tool life minimum costs and the efficient reporting of specific restrictions for finishing and rough...

BACKGROUND During the last few decades, high-resolution computed tomography (HRCT) has come up as a new diagnostic modality to diagnose emphysematous and chronic bronchitis components of chronic obstructive pulmonary disease (COPD).
