DEVELOPMENT AND REALISATION OF A FULLY AUTOMATIC TESTING FACILITY FOR DETERMINING THE VOLUME OF E1 WEIGHTS UP TO 50 kg BASED ON HYDROSTATIC WEIGHING

چکیده

The Federal Office of Metrology and Surveying (BEV, Austria) has developed and realised a new fully automatic test System for hydrostatic weighing and determining the density of solids up to 50 kg. This volume comparator allows a full automatically determination of the volume of E1 weights and plummets in the range from 1 kg up to 50 kg through direct comparison with one single volume reference (e.g. a Silicium sphere) with high accuracy. In this volume comparator, two hydrostatic weighing systems for density determination work simultaneously together so that it is possible to compare the density of a small, well-known standard sinker directly with the density of a submerged solid with masses up to 50 kg.

DCU at Generation Challenges 2011 Surface Realisation Track

In this paper we describe our system and experimental results on the development set of the Surface Realisation Shared Task. DCU submitted 1-best outputs for the Shallow subtask of the shared task, using a surface realisation technique based on dependency-based n-gram models. The surface realiser achieved BLEU and NIST scores of 0.8615 and 13.6841 respectively on the SR development set.

Model-driven Development of Self-managing Software Systems

The promise of self-management is to increase the dependability of complex software systems and its quality-of-service. However, self-management is a very complex task if implemented manually at code level. It introduces high risks to the system’s maintainability and dependability. Model-driven development of self-management at the architectural level is a promising alternative to manual low-le...

Using an HPSG grammar for the generation of prosodic structures

In this paper, we report on an experiment showing how the introduction of prosodic information from detailed syntactic structures into synthetic speech leads to better disambiguation of structurally ambiguous sentences. Using modifier attachment (MA) ambiguities and subject/object fronting (OF) in German as test cases, we show that prosody which is automatically generated from deep syntactic in...

OntoCase - A Pattern-Based Ontology Construction Approach

As the technologies facilitating the Semantic Web become more and more mature they are also adopted by the business world. When developing semantic applications, constructing the underlying ontologies is a crucial part. Construction of enterprise ontologies need to be semi-automatic in order to reduce the effort required and the need for expert ontology engineers. Another important issue is to ...
