Abstract:

Le dioxyde de carbone supercritique (SF-CO2) a été choisi afin d'étudier l'extraction en milieu supercritique d'ions métalliques tels que le césium et l'uranium. Un intérêt particulier a été porté au rôle de l'eau lors de ces extractions ainsi qu'à son interaction avec des agents chélateurs (AC). En première partie, les éthers couronne ont été choisis comme AC du césium et leur interaction avec l'eau a été étudiée dans le SF-CO2 en utilisant la spectroscopie InfraRouge à Transformée de Fourier (IR-TF). La configuration sandwich entre deux éthers couronne et une molécule d'eau a été observée da

<p>Invasive Candida infection is an increasing cause of morbidity and mortality in the immunocompromised patient. Molecular diagnosis based on genomic amplification methods, such as real time PCR, has been reported as an alternative to conventional culture for early detection of invasive candidiasis. The template DNA extraction step has been the major limitation in most reported nucleic acid based assays, due to problems in breaking fungal cell walls and incomplete purification in PCR inhibitor substances.</p><p>The aim of this study was to compare enzymatic cell wall disruption using recombin

Abstract:

Testing an integrated information system that relies on data from multiple sources can be a challenge, particularly when the data is confidential. This thesis describes a novel test data extraction approach, called semantic-based test data extraction for integrated systems (iSTDE) that solves many of the problems associated with creating realistic test data for integrated information systems containing confidential data. iSTDE reads a consistent cross-section of data from the production databases, manipulates that data to obscure individual identities while still preserving overall semantic da

Abstract:

A lot of research have been carried in the field of optical character recognition. Selection of a feature extraction scheme is probably the most important factor in achieving high recognition performance. Fourier and wavelet transforms are among the popular feature extraction techniques allowing rotation invariant recognition. The performance of a particular feature extraction technique depends on the used dataset and the classifier. Dierent feature types may need dierent types of classifiers. In this thesis Fourier and wavelet based features are compared in terms of classification accuracy. T

Fourteen word frequency metrics were tested to evaluate their effectiveness in identifying vocabulary in a domain. Fifteen domain engineering projects were examined to measure how closely the vocabularies selected by the fourteen word frequency metrics were to the vocabularies produced by domain engineers. Six filtering mechanisms were also evaluated to measure their impact on selecting proper vocabulary terms. The results of the experiment show that stemming and stop word removal do improve overlap scores and that term frequency is a valuable contributor to overlap. Variations on term frequ

Abstract:

Image based screening is an important tool used in research for development of drugs to fight cancer. Phase contrast video microscopy - a cheap and fast image screening technology - enables a rapid generation of large amounts of data, which requires a fast method for analysis of this data. As videos contain a lot of redundant information, the difficulty is to extract usable information in form of features from the videos, by compressing available information, or filter out redundant data. In this thesis, the problem is approached in an experimental fashion where three different methods have be

Extracting functional dependencies from existing databases is a useful technique in relational theory, database design and data mining. Functional dependencies are a key property of relational schema design. A functional dependency is a database constraint between two sets of attributes. In this study we present a comparative study over TANE, FUN, FD_Mine, FastFDs and Dep_Miner, and we propose a new technique, KlipFind, to extract dependencies from relations efficiently. KlipFind employs a depth-first, heuristic driven approach as a solution. Our study indicates that KlipFind is more spa

The increasing demand for alternatives to meat food products, which is linked to ethical and environmental reasons, highlights the necessity of using different protein sources. Plant proteins provide a valid option, thanks to the relative low costs, high availability and wide supply sources. The current process used to produce plant concentrates and isolates is the alkaline extraction followed by isoelectric precipitation. However, despite the high purity of the proteins, it presents some drawbacks. Innovative protein extraction processes are emerging, with the aim of reducing the environmenta

A brain-machine interface (BMI) is a system that allows the communication between the central nervous system (CNS) and an external device (Wolpaw et al. 2002). Applications of BMIs include the control of external prostheses, cursors and spellers, to name a few. The BMIs developed by various research groups differ in their characteristics (e.g. continuous or discrete, synchronous or asynchronous, degrees of freedom, others) and, in spite of several initiatives towards standardization and guidelines, the cross comparison across studies remains a challenge (Brunner et al. 2015; Thompson et al. 20

The aim of this work is to design methods of fingerprint morphing, subsequently to implement the proposed methods and to test their effectiveness by breaking into real verification systems made by Innovatrics and Neurotechnology, two prominent companies in biometrics. Methods for morphing were designed mainly based on the article On the Feasibility of Creating Double-Identity Fingerprints where the part of the preparation of fingerprints on the input was modified and an adjustment of the output was made so that it is able to work with fingerprint images taken under different conditions.

Abstract:

Investigation of non metallic inclusions in two different steels from Sandvik was made before and after turning. After dissolving the non-metallic inclusions by electrolytic extraction the particles were analysed manually or by INCA feature. This was referred to as 3D analysis. INCA feature analysis without extraction of particles was also performed, this was referred to as 2D analysis. The aim of the report was to a make a characterization of non-metallic inclusions with respect to chemical composition, aspect ratio, size and shape. The aim was also to compare different investigation methods.

Abstract:

<p>The current Environmental Protection Agency (EPA) method utilized for analysis of trace organic chemicals and heavy metals leached from solid waste is the Extraction Procedure (EP) Toxicity Test. Because of various operational problems and limitations of the EP, the EPA has developed and plans to implement the Toxicity Characteristic Leaching Procedure (TCLP), which is an expanded version of the EP capable of analyzing more organic components, in particular volatile organic chemicals.</p> <p>The purpose of this research was to investigate and compare the ability of the EP and TCLP

They are also the totality of the cultural viewpoints, the dominant achievements, the measuring techniques and the drawing techniques. The historical trajectories are recorded with maps, so the map becomes a way of history recording. The major purpose of this research is to extract the multiple information of Taiwan maps. 35 Taiwan maps across approximately 280 years are selected for the study. By the steps of geo-referencing, digitization and characterization, many kinds

The feasibility and efficiency of various rapeseed oil extraction systems with hexane, ethanol and water as solvents were studied and compared. Mathematical model of multi-stage counter-current-flow extraction was build and verified in this research. Six-stage counter-current-flow extraction experiments were carried with two different solvent to raffinate ratio (E/R) i.e. E/R=4, 8. A better result was found with E/R=4, that gave 90% in oil recovery and 8~9% (w/w) oil concentratio

Unfortunately, because of the explosion in patent documents and the claim formats are full of variety, the technologies of patent documents in search、analysis、and comparison have faced some serious bottleneck. In my thesis, I propose an approach to extract the semantic structure of claim and compare their difference on the basis of semantic structures. In the aspect of se
