iii The methodology exploited to evaluate the performance of the framework involves the development of algorithms, their implementation in software, and their assessment using welldesigned experiments anchored on quantitative performance measurement methods. The goodness-of-fit coefficient (GFC) is used to evaluate the performance of the framework, by measuring the degree of similarity between ...

The present study looks into the variations in frequencies and pragmatic functions of metadiscourse markers known as boosters, particular, with regard to their verb forms. Three corpora have been compiled this end, covering fields engineering, medicine linguistics. were manually annotated for markers, boosters included, by a group annotators. A predetermined list was used annotation, but throug...

Small-molecule inhibitors of the mycobacterial transcriptional repressor EthR have previously been shown to act as boosters of the second-line antituberculosis drug ethionamide. Fragment-based drug discovery approaches have been used in the past to make highly potent EthR inhibitors with ethionamide boosting activity both in vitro and ex vivo. Herein, we report the development of fragment-sized...

Four sample space launch missions were designed using rotating momentum transfer tethers (bolos) within low Earth orbit and a previously unknown phenomenon of ―aerospinning‖ was identified and simulated. The momentum transfer tethers were found to be only marginally more efficient than the use of chemical rocket boosters. Insufficient power density of modern spacecrafts was identified as the pr...

Using a system analysis approach compares different systems for handling and treatment of toilet waste and organic household waste. Design issues considered are source separation of urine, use of vacuum toilets and advanced nutrient recovery processes such as Reverse Osmosis (RO). All of the studied systems have low emissions of eutrophying compounds. Other environmental effects are mainly rela...

traditional systems for olefin/paraffin separation, like low-temperature distillation, are expensive and very energy consuming, and therefore, alternative separation methods are desired. facilitated transport membranes are new tools for this separation to be substituted in large scale separation of olefin-paraffin mixtures. to design a membrane process for olefin-paraffin separation, equilibriu...

blind source separation technique separates mixed signals blindly without any information on the mixing system. in this paper, we have used two evolutionary algorithms, namely, genetic algorithm and particle swarm optimization for blind source separation. in these techniques a novel fitness function that is based on the mutual information and high order statistics is proposed. in order to evalu...

Recent interpretations of the Adaboost algorithm view it as performing a gradient descent on a potential function. Simply changing the potential function allows one to create new algorithms related to AdaBoost. However, these new algorithms are generally not known to have the formal boosting property. This paper examines the question of which potential functions lead to new algorithms that are ...
