Analysis of Multilocus Sequence Typing and Virulence Characterization of Listeria monocytogenes Isolates from Chinese Retail Ready-to-Eat Food
2016
Eighty Listeria monocytogenes isolates were obtained from Chinese retail ready-to-eat (RTE) food and were previously characterized with serotyping and antibiotic susceptibility tests. The aim of this study was to characterize the subtype and virulence potential of these L. monocytogenes isolates by multilocus sequence typing (MLST), virulence-associate genes, epidemic clones (ECs), and sequence analysis of the important virulence factor: internalin A (inlA). The result of MLST revealed that these L. monocytogenes isolates belonged to 14 different sequence types (STs). With the exception of four new STs (ST804, ST805, ST806, and ST807), all other STs observed in this study have been associat…

Large-scale nonlinear dimensionality reduction for network intrusion detection
2017
International audience; Network intrusion detection (NID) is a complex classification problem. In this paper, we combine classification with recent and scalable nonlinear dimensionality reduction (NLDR) methods. Classification and DR are not necessarily adversarial, provided adequate cluster magnification occurring in NLDR methods like $t$-SNE: DR mitigates the curse of dimensionality, while cluster magnification can maintain class separability. We demonstrate experimentally the effectiveness of the approach by analyzing and comparing results on the big KDD99 dataset, using both NLDR quality assessment and classification rate for SVMs and random forests. Since data involves features of mixe…
Removal of Cu(II) and Pb(II) from aqueous solutions by lacit acid bacteria
2015
Celem pracy było porównanie zdolności usuwania Cu(II) i Pb(II) z roztworu wodnego przez bakterie kwasu mlekowego (LAB). Badano wpływ różnych parametrów, tj. stężenia jonów metali, pH i czas kontaktu, na proces usuwania jonów miedzi i ołowiu. Do opisu izoterm adsorpcji jonów metali przez biomasę LAB zastosowano modele Langmuira i Freundlicha. Uzyskane dane doświadczalne były lepiej dopasowane do modelu Langmuira niż Freundlicha. Sorbent wykazał maksymalną zdolność sorpcyjną, wynoszącą 11,07 i 10.51 mg · g–1 odpowiednio dla jonów Cu(II) i Pb(II). Optymalne warunki biosorpcji obu jonów metali wynosiły: pH 6,0 i czas równowagi 40 minut. Omówiono również udział grup funkcyjnych na powierzchni bi…
A HUMAN RESOURCE ONTOLOGY FOR RECRUITMENT PROCESS
2009
In this paper we propose a model of ontology for the human resource domain. We emphasize the benefits resulting from the application of Semantic Web technologies in the recruitment process. We use currently available standards and classifications to develop a human resource ontology which gives us means for semantic annotation of job postings and applications. Furthermore, we outline the process of semantic matching which improves the quality of query results. Finally, we propose the architecture of an evaluation system based on Semantic Web technologies.
On UML modeling tool evaluation, use and training
2017
Unified Modeling Language™ (UML) is an international standard for systems modeling. UML is used for modeling requirements, architecture, detailed design, and software code generation. UML modeling tools offer graphical editors for UML model development, generating software from UML models, creating UML models from the software, and supporting collaborative model development. This thesis offers new knowledge about UML modeling tool use, evaluation, and training. The main research question is: How can a globally distributed product company where UML modeling activities are scattered across different locations and countries implement a UML modeling tool? Five studies comprise the research proc…

Tiedonlouhinta rakenteisista dokumenteista
2005
Tutkielman kokonaistavoite on vastata tietotulvan tuomiin haasteisiin tiedonlouhinnan tekniikoita käyttäen. Yleisenä tutkimuskohteena on tiedonlouhinta rakenteisista dokumenteista. Täsmällisemmin määriteltynä tutkimusongelma käsittää samaa skeemaa noudattavien XML-dokumenttien klusteroinnin ja tiedonhaun. Lisäksi käsitellään erilaisten haku- ja klusterointitekniikoiden yhdistämisen tuomia mahdollisuuksia dokumenttikokoelmien hahmottamisessa. Teoreettisessa osuudessa käydään läpi erilaisia indeksirakenteita, samanlaisuusmittoja, klusterointialgoritmeja ja hakumenetelmiä. Empiirisessä osuudessa on kehitetty ExtMiner-sovellus, joka tukee hakua, klusterointia ja visualisointia erilaisille XML-d…
