We discuss the design and the implementation of a flexible and scalable fuzzy case-based matching engine. The engine’s flexible design is illustrated for two of its core components: the internal representation of cases by means of a variety of crisp and fuzzy data types, and the fuzzy operations to execute the ensuing case matching process. We investigate the scalability of the matching engine ...

In the present work, the influence of a very early pilot injection on pollutant formation was investigated in a Common-Rail DI Diesel engine. The engine was operated at conventional part-load conditions at 2000 rpm, an EGR variation was done and the injected fuel mass was 15 mm^3/cycle. The Nozzle type were conical and flow optimized geometries (ks nozzle) with hole diameters of 0.141 mm, lengt...

This study investigates dynamic & static behaviour of automotive engine crankshaft with the specific conditions. This work investigates the coupled modes, including, couple torsional flexural vibration and coupled longitudinal flexural vibration for non rotating engine crankshaft. The finite element models of this generally used are in two categories beam elements and solid elements and in this...

This study discusses the performance and combustion characteristics of a direct injection (DI) diesel engine fueled with biodiesels such as waste (frying) palm oil methyl ester (WPOME) and canola oil methyl ester (COME). In order to determine the performance and combustion characteristics, the experiments were conducted at the constant engine speed mode (1500 rpm) under the full load condition ...

In this study, mustard biodiesel (B100) was produced from low quality crude mustard oil and tested in a four-cylinder, direct-injection, diesel engine to investigate the combustion, performance and emission characteristics of the engine at different engine speeds and full load conditions. Biodiesel and its blends showed increased peak cylinder pressure and reduced ignition delay when compared t...

Borealis is a distributed stream processing engine that has been developed at Brandeis University, Brown University, and MIT. It extends the first generation of data stream processing systems with advanced capabilities such as distributed operation, scalability with timevarying load, high availability against failures, and dynamic data and query modifications. In this paper, we focus on aspects...

Presented paper shows results of laboratory tests on the relationship between the throttling of a cross area of an air intake duct and the composition of exhaust gas from the marine engine. The object of research is a laboratory four-stroke diesel engine, worked with a load from 50kW to 250kW at a constant speed. During the laboratory, tests over 50 parameters were measured of the engine with t...

The thermal management of modern aircraft has become more challenging as aircraft capabilities have increased. The use of thermally resistant composite skins and the desired for low observability, reduced ram inlet size and number, has reduced the ability to transfer heat generated by the aircraft to the environment. As the ability to remove heat from modern aircraft has decreased, the heat loa...

We investigate the confrontation of load splitting and caching in high-performance parallel network forwarding systems. Our study demonstrates that hashbased load splitting schemes tend to significantly improve the temporal locality of the address stream submitted to a single routing engine (RE), which in turn greatly facilitates caching as a means of increasing system performance. We also show...
