In this paper we present the set-oriented bottom-up parsing system AMOS which is a major application of the deductive database system LOLA. AMOS supports the morpho-syntactical analysis of old Hebrew and has now been operationally used by linguists for a couple of years. The system allows the declarative specification of Definite Clause Grammar rules. Due to the set-oriented bottom-up evaluatio...

A main memory object-relational database system, AMOS II, has been developed at Uppsala Database Laboratory (UDBL). The system provides common database facilities and a powerful query language but also, through it’s mediator-wrapper approach, features for the combination of data from heterogeneous data sources. The AMOS II query processor is extensible through a generalized foreign function mec...

Animals can move in not only elegant but also energy efficient ways. Their skin is one of the key components for this achievement. It provides a proper friction for forward motion and can protect them from slipping on a surface during locomotion. Inspired by this, we applied real shark skin to the foot soles of our hexapod robot AMOS. The material is formed to cover each foot of AMOS. Due to sh...

Emerging mobile and ubiquitous computing environments present hard challenges to software engineering. The use of mobile code has been suggested as a natural fit for simplifying software development for these environments. Existing strategies for locating mobile code assume an underlying fixed, stable network. An alternative approach is required for mobile environments, where network size and r...
