A knowledge-based system for liquid retaining structure design with blackboard architecture

Owing to the high degree of vulnerability of liquid retaining structures to corrosion problems, there are stringent requirements in its design against cracking. In this paper, a prototype knowledge-based system is developed and implemented for the design of liquid retaining structures based on the blackboard architecture. A commercially available expert system shell VISUAL RULE STUDIO working as an ActiveX Designer under the VISUAL BASIC programming environment is employed. Hybrid knowledge representation approach with production rules and procedural methods under object-oriented programming are used to represent the engineering heuristics and design knowledge of this domain. It is demonstrated that the blackboard architecture is capable of integrating different knowledge together in an effective manner. The system is tailored to give advice to users regarding preliminary design, loading specification and optimized configuration selection of this type of structure. An example of application is given to illustrate the capabilities of the prototype system in transferring knowledge on liquid retaining structure to novice engineers. (C) 2004 Elsevier Ltd.

Physiologically based synthetic models of hepatic disposition

Current Physiologically based pharmacokinetic (PBPK) models are inductive. We present an additional, different approach that is based on the synthetic rather than the inductive approach to modeling and simulation. It relies on object-oriented programming A model of the referent system in its experimental context is synthesized by assembling objects that represent components such as molecules, cells, aspects of tissue architecture, catheters, etc. The single pass perfused rat liver has been well described in evaluating hepatic drug pharmacokinetics (PK) and is the system on which we focus. In silico experiments begin with administration of objects representing actual compounds. Data are collected in a manner analogous to that in the referent PK experiments. The synthetic modeling method allows for recognition and representation of discrete event and discrete time processes, as well as heterogeneity in organization, function, and spatial effects. An application is developed for sucrose and antipyrine, administered separately and together PBPK modeling has made extensive progress in characterizing abstracted PK properties but this has also been its limitation. Now, other important questions and possible extensions emerge. How are these PK properties and the observed behaviors generated? The inherent heuristic limitations of traditional models have hindered getting meaningful, detailed answers to such questions. Synthetic models of the type described here are specifically intended to help answer such questions. Analogous to wet-lab experimental models, they retain their applicability even when broken apart into sub-components. Having and applying this new class of models along with traditional PK modeling methods is expected to increase the productivity of pharmaceutical research at all levels that make use of modeling and simulation.

For this purpose, terminology, classification, and models, proposed by the author, are employed. As examples of integrated expert systems, Russian systems designed in this field and available to the majority of specialists are analyzed.

Distance Matrix Approach to Content Image Retrieval

As the volume of image data and the need of using it in various applications is growing significantly in the last days it brings a necessity of retrieval efficiency and effectiveness. Unfortunately, existing indexing methods are not applicable to a wide range of problem-oriented fields due to their operating time limitations and strong dependency on the traditional descriptors extracted from the image. To meet higher requirements, a novel distance-based indexing method for region-based image retrieval has been proposed and investigated. The method creates premises for considering embedded partitions of images to carry out the search with different refinement or roughening level and so to seek the image meaningful content.

A Representation of Binary Matrices

Христина Костадинова, Красимир Йорджев - В статията се обсъжда представянето на произволна бинарна матрица с помощта на последователност от цели неотрицателни числа. Разгледани са някои предимства и недостатъци на това представяне като алтернатива на стандартното, общоприето представяне чрез двумерен масив. Показано е, че представянето на бинарните матрици с помощта на наредени n-торки от естествени числа води до по-бързи алгоритми и до съществена икономия на оперативна памет. Използуван е апарата на обектно-ориентираното програмиране със синтаксиса и семантиката на езика C++.

What can practitioner perceptions tell us about our subject?

Part of the challenge of fostering learning is to open up learner minds to new possibilities or ways of thinking but is what we are encouraging learners to think really that different from the current practitioner conceptions? Having been uncomfortable with the focus of textbooks for the teaching of the core concept, the nature of a program, in the teaching of object-­oriented programming, we sought to discover how practitioner’s conceived the concept. Our findings provide a framework for understanding the different ways of conceiving the concept and the features that distinguish these conceptions. How could these conceptions and their critical features influence the focus in teaching especially in relation to computational thinking?

REST SERVER IN JOLIE - Practical Case

The aim of this thesis is to merge two of the emerging paradigms about web programming: RESTful Web Development and Service-Oriented Programming. REST is the main architectural paradigm about web applications, they are characterised by procedural structure which avoid the use of handshaking mechanisms. Even though REST has a standard structure to access the resources of the web applications, the backend side is usually not very modular if not complicated. Service-Oriented Programming, instead, has as one of the fundamental principles, the modularisation of the components. Service-Oriented Applications are characterised by separate modules that allow to simplify the devel- opment of the web applications. There are very few example of integration between these two technologies: it seems therefore reasonable to merge them. In this thesis the methodologies studied to reach this results are explored through an application that helps to handle documents and notes among several users, called MergeFly. The MergeFly practical case, once that all the specifics had been set, will be utilised in order to develop and handle HTTP requests through SOAP. In this document will be first defined the 1) characteristics of the application, 2) SOAP technology, partially introduced the 3) Jolie Language, 4) REST and finally a 5) Jolie-REST implementation will be offered through the MergeFly case. It is indeed implemented a token mechanism for authentication: it has been first discarded sessions and cookies algorithm of authentication in so far not into the pure RESTness theory, even if often used). In the final part the functionality and effectiveness of the results will be evaluated, judging the Jolie-REST duo.

Exploration du rôle modérateur des stratégies d’adaptation sur la relation entre les mauvais traitements perçus et les problèmes psychologiques d’adolescents à risque

Les adolescents qui ont subi de la négligence ou des abus substantiels dans leur famille risquent de présenter des symptômes anxieux et dépressifs et des comportements antisociaux plus importants. Parmi les ressources internes qui pourraient contribuer à la résilience de ces jeunes, les stratégies qu’ils adoptent pour composer avec les situations stressantes ont été peu examinées. Dans cette thèse, nous examinons les stratégies d’adaptation utilisées par 336 adolescents placés en centre de réadaptation, avec pour objectif de vérifier leur rôle modérateur dans la relation entre les mauvais traitements qu’ils perçoivent et l’ampleur de leurs problèmes intériorisés ou extériorisés. Le premier chapitre présente une revue de la recherche sur les liens entre divers stresseurs, les stratégies d’adaptation des jeunes et leur condition psychologique. Ces études mettent en lumière combien les effets des stratégies qu’ils utilisent peuvent varier selon les stresseurs familiaux ou sociaux auxquels ils sont exposés. Les deux études empiriques aux chapitres 2 et 3 portent sur les interactions entre trois types de maltraitance (abus émotionnel ou physique, négligence émotionnelle) et quatre stratégies d’adaptation (centrées sur les problèmes, les émotions, la diversion sociale et la distraction). Dans la première étude, ces interactions sont testées pour leurs effets sur l’ampleur des problèmes intériorisés rapportés par les jeunes ou leurs éducateurs; la seconde étude explore leurs effets sur l’ampleur des problèmes extériorisés. Quand les problèmes intériorisés sont rapportés par les adolescents, les stratégies centrées sur les problèmes, la diversion sociale et la distraction avaient un effet protecteur sur l’ampleur des symptômes associés à la maltraitance émotionnelle, surtout chez les filles. Les stratégies centrées sur les problèmes ont aussi un effet protecteur sur la relation entre l’abus émotionnel et les comportements agressifs rapportés par les jeunes. Toutefois quand il s’agit des problèmes extériorisés, plusieurs interactions montrent plutôt que les effets adaptatifs de certaines stratégies diminuent quand les mauvais traitements augmentent. Il en est ainsi pour les stratégies centrées sur les problèmes ou la diversion sociale quand ces problèmes sont observés par les éducateurs, et pour les distractions, lorsqu’ils sont rapportés par les filles. Enfin la diversion sociale est associée à des comportements délinquants plus marqués rapportés par les jeunes et son effet modérateur chez les garçons montre que cette relation est plus forte quand ils sont moins maltraités. Les stratégies d’adaptation examinées contribuent donc surtout à atténuer la détresse émotionnelle des filles victimes de maltraitance psychologique, mais elles semblent avoir peu d’impact sur les comportements antisociaux des jeunes maltraités. Ces résultats sont discutés en lien avec les caractéristiques de notre échantillon. Les implications cliniques qui s’en dégagent permettent de suggérer des pistes pour mieux soutenir ces jeunes dans l’apprentissage de stratégies adaptatives pour réguler leur stress.

Vain lakiko lasta suojelee?

Tiivistelmä TURUN YLIOPISTO Oikeustieteellinen tiedekunta Perhe-oikeus VALJAKKA EEVA: Vain lakiko lasta suojelee? Väitöskirja, 219 s. Kesäkuu 2016 Tutkimuksessa tarkastellaan suomalaisen lastensuojelulainsäädännön pitkän ai- kavälin kehitystä 1800-luvun lopulta 2010-luvulle. Tavoitteena on selvittää, mil- lä tavoin lasten suojelun tarvetta on lastensuojelulakeja säädettäessä määritelty ja millaisin keinoin julkinen valta on suojellut lapsia. Tutkimuksessa luodaan myös yleisemmin kuvaa siitä, millaista keskustelua lastensuojelun yhteiskunnallisesta tehtävästä, yksityisen ja julkisen hyvinvointivastuun jakautumisesta sekä julkisen vallan perheen yksityisyyteen puuttuvien toimien tarpeellisuudesta ja oikeutukses- ta on eri aikoina käyty. Tutkimuksessa lastensuojelun käsitettä käytetään sekä laa- jemmassa (Child Welfare) että suppeammassa (Child Protection) merkityksessä. Tutkimus on lapsi- ja oikeuspoliittinen puheenvuoro, jossa lastensuojelun institutionaalisia kehityskulkuja tarkastellaan yhteiskunnassa sosioekonomisesti heikoimmassa asemassa olevan lapsiväestön ja lastensuojelun asiakkaiksi valikoi- tuvien lasten näkökulmasta. Tutkimusote on ongelmalähtöinen ja yhteyshakuinen siten, että tutkimuskysymyksiä tarkastellaan monitieteisesti hallinto- ja sosiaalioi- keudellisessa viitekehyksessä. Tutkimus osoittaa, että tarkasteltaessa lastensuojelua käsitteen suppeam- massa merkityksessä lastensuojeluinstituution rakenteet kuten lasten suojelutar- peen määrittely, suojelun keinot ja lastensuojelulain julkilausutut tavoitteet ovat pysyneet lähes samankaltaisina aina ensimmäisen lastensuojelulain (1936) säätä- misestä lukien. Tarkasteltaessa lastensuojelua käsitteen laajemmassa merkityksessä voidaan lastensuojelussa nähdä tapahtuneen muutoksia. Vähitellen hyvinvointivaltion laajentuessa lastensuojelua koskeva ymmärrys muuttui yhä moniulotteisemmak- si. Lastensuojelu merkitsi 1960-luvulle tultaessa laajaa lapsiväestön hyvinvointia turvaavaa yhteiskuntapoliittista ohjelmaa. Myös sosiaalipolitiikan suunnanmuutos 1990-luvulla ja sen myötä julkisen vallan vastuun kaventaminen merkitsivät muu- tosta lastensuojelussa. Monille yhteiskunnan eri osa-aluille ulottuvien perheiden ja lasten hyvinvointia tavoittelevien politiikkaohjelmien ja niiden toteuttamispyrki- mysten sijaan lastensuojelu kaventui niin käsitteenä kuin käytännön toimintanakin tarkoittamaan lähes yksinomaan sosiaalihuollon erityispalvelua eli lapsi- ja perhe- kohtaista lastensuojelua. Asiasanat: Lastensuojelu, lastensuojelulainsäädäntö, historiallinen kehitys, oikeu- dellinen sääntely, hyvinvointivaltio.
