Dynamic faceted search for discovery-driven analysis

We propose a dynamic faceted search system for discovery-driven analysis on data with both textual content and structured attributes. From a keyword query, we want to dynamically select a small set of "interesting" attributes and present aggregates on them ...

Prechamber autoignition of gaseous mixtures: numerical simulation with detailed chemistry and testing on engine test bench

Daniel Favrat, Stefan Heyne

The work accomplished during the second period of the project mainly focused on the experimental evaluation of the prechamber system comparing its performance regarding emissions and efficiency to standard spark ignition mode. Further instrumentation of th ...

NUMERICAL FLOW SIMULATION OF A NATURAL GAS ENGINE EQUIPPED WITH AN UNSCAVANGED AUTO-IGNITION PRECHAMBER

Daniel Favrat, Jan-Bernhard Vos, Stefan Heyne, Dirk Wunsch

This work is part of ongoing research on stationary natural gas engines equipped with unscavanged prechambers. Spark ignition inside the prechamber has been successfully proven with natural gas as well as biogas, reducing emissions while keeping good effic ...

A Search Engine for QoS-enabled Discovery of Semantic Web Services

Karl Aberer, Manfred Hauswirth

Directory services are a genuine constituent of any distributed architecture which facilitate binding attributes to names and then querying this information, that is, announcing and discovering resources. In such contexts, especially in a business environm ...

Thermo economic analysis for the optimal conceptual design of biomass gasification energy conversion systems

François Maréchal, Martin Gassner, David Brown

This study addresses the thermo economic assessment of a biomass gasification, gas cleaning and energy conversion process, with particular attention given to tar control and the communication of the process design rationale. Product distributions were esti ...

Multicriteria Optimisation of Small Hybrid Solar Power System.

Daniel Favrat, El Hadj Malick Kane

A new concept of small hybrid solar power system (HSPS) has been successfully demonstrated in the context of a project called SPS (Solar Power System). This plant integrates two rows of solar collectors, two superposed Organic Rankine Cycles (ORC) each equ ...

An experimental investigation of a lean burn natural gas prechamber spark ignition engine for cogeneration

Roger Röthlisberger

The operation of a cogeneration internal combustion engine with unscavenged prechamber ignition was investigated. The objective was to evaluate the potential to reduce the exhaust gas emissions, particularly the CO emissions, below the Swiss limits (NOx an ...
