The subject of uncertainty analysis in complex systems design is a broad and bourgeoning field of study. This paper focuses on only three very specific areas of current propulsion research wherein uncertainty plays a pivotal role in the problem formulation. The first is probabilistic approaches to matching engine cycle models to test data. Engine cycle models must have a high confidence of repr...

Search engine optimization [SEO] is often about making modifications to parts of the website. When viewed individually, these changes might seem like incremental improvements, but when combined with optimization technique, they could have noticeable impact on website’s user experience and performance in search results. SEO requires considerable time, professional communicators should progressiv...

The lubrication system of an internal combustion engine serves many purposes. It lubricates moving parts, cools the engine, removes impurities, supports loads, and minimizes friction. The entrapment of air in the lubricating oil is called oil aeration. Oil aeration can be detrimental to internal combustion (IC) engines. This study attempts to determine a means to reduce the level of aeration in...

We present D-SPARQ, a distributed RDF query engine that combines the MapReduce processing framework with a NoSQL distributed data store, MongoDB. The performance of processing SPARQL queries mainly depends on the efficiency of handling the join operations between the RDF triple patterns. Our system features two unique characteristics that enable efficiently tackling this challenge: 1) Identifyi...

The topic of this paper is the object oriented modeling of a Common Rail Direct Injection System of a gasoline engine. The injection system of a gasoline engine is described; the main functional elements are detailed and an object oriented implementation using the Modelica language is proposed. The availability of a fast and easily reconfigurable simulator allows to study how different parts of...

Our experiments in the Robust track this year focused on predicting query difficulty and using this prediction for improving information retrieval. We developed two prediction algorithms and used the subsequent prediction in several ways in order to improve the performance of the search engine. These included modifying the search engine parameters, using selective query expansion, and switching...

j-POST is an integrated toolchain for property-oriented software testing. This toolchain includes a test designer, a test generator, and a test execution engine. The test generation is based on an original approach which consists of deriving a set of communicating test processes obtained both from a requirement formula (expressed in a trace-based logic) and a behavioral specification of some sp...
