Matematikos integravimas pagrindinėje mokykloje / Integration of mathematics in basic schoolAniulis, Andrius 09 July 2011 (has links)
Vilniaus universiteto Matematikos ir informatikos fakulteto studento Andriaus Aniulio magistriniame darbe trumpai apžvelgta integracijos procesos svarba dabartinės visuomenės ekonomikos ir politikos srityje, tačiau didžiausias dėmesys sutelktas į integracijos procesą, vykstantį bendrojo lavinimo mokyklose. Taigi integracijso procesas nėra tik globalinis procesas, aktualus valstybi valdyme, bet ir svarbus veiksnys, visuomenės formavime ir ugdyme Dėl jo vertės švietimo sistemoje diskutuojama jau nuo Antikos laikų, bet itin aktyviai paskutiniuosius 50 metų. Dabar jau prieita neginčijama nuomonė, kad tarpdalykinis (integruotas) mokymas suteikia mokiniams prasmingą atskirų mokomųjų dalykų supratimą. Juk gyvenime nėra atskirų dalykų, nes čia kartu prireikia ir ekonominkos, ir geografijos, ir matematikos žinių, todėl sėkmingiausios pamokos tos, kuriose jungiami (integruojami) du, trys ar keli dalykai. Norint atskleisti integracijso procesą bendrojo lavinimo mokyklose Lietuvoje, išanalizuotas vienas svarbiausių Lietuvos Švietimo ir mokslo ministerijos išleistas dokumentas ,,Atnaujintos pradinio ir pagrindinio ugdymo bendrosios programos“ (2009). Remiantis ir integracijos proceso istorija, bandoma pažvelgti į vidinę ir tarpdalykinę integraciją, vykstančią dabartinėse mokyklose. Tam tikslui pateikta anketa šešių Lietuvos mokyklų mokytojams ir ištirtas jų požiūris į integruotų pamokų tikslingumą. Visų tirtų mokyklų mokytojų dauguma pasisako už integruotas pamokas ir įžvelgia naudos:... [toliau žr. visą tekstą] / Vilnius University, Faculty of Mathematics and Computer Science student Andrius Aniulis in his theses briefly overviewed the importance of the integration process in the area of current public economics and politics, however the central focus was placed on the integration process in general education schools. Hence the integration process is not only a global process which is important in the governance of the state,but also it is an important factor which contributes to the formation and the education of the society.The discussions about the value of the integration process in educational system have taken place since ancient times, but they have been very active for the last 50 years. Now It is a common ground that an interdisciplinary (integrated) teaching provides students with a meaningful understanding of individual subjects. After all, life does not consist of separate things, in everyday life you need the knowledge of economics, geography, mathematics etc. for this reason the most successful lessons are those which connect (integrate) two, three or more subjects. In order to reveal the integration process in Lithuanian general education schools one of the most important documents issued by Lithuanian Ministry of Education was analyzed, 'Updated general programs of primary and lower secondary education' (2009). Based on the history of integration process the attempt is made to look at the internal and cross-curricular integration which is taking place in the current... [to full text]

Video summary based on rate-distortion criterionChou, Chih-Wei 24 July 2008 (has links)
Due to advanced in computer technology¡Avideo data are becoming available in the daily life. The method of managing Multi-media video database is more and more important¡Aand traditional database management for text documents is not suitable for video database; therefore, efficient video database must equip video summary. Video summarization contains a number of key-frame and the key-frame is a simple yet effective form of summarizing a video sequence and the video summarization help user browses rapidly and effectively find out video that the user wants to find. Video summarization except extraction of key-frame has another important key, the number of key-frame. When storage and network bandwidth are limited, the number of key-frame must conform to the limit condition and as far as possible find the representative key-frame. Video summarization is important topic for managing Multi-media video.
The number of key-frame in video summarization is related to distortion between video summarization and original video sequence. The number of key-frame is more, the distortion between video summarization and original video sequence is smaller. This paper emphasizes key-frame extraction and the rate of key-frame. First the user inputs the number of key-frame and then extracts the key-frame that has smallest distortion between original video sequence in key-frame number limit situation. In order to understand the entire video structure¡Athe Normalized the graph cuts(NCuts) group method is carried out to cluster similar video paragraph. The resulting clusters form a direction temporal graph and a shortest path algorithm is proposed to find main structure of video. The performance of the proposed method is demonstrated by experiments on a collection of videos from Open Vide Project. We provided a meaningful comparison between results of the proposed summarization with Open Vide storyboard and the PME based approach.

Multilingual UDC Summary Online Project: 2009 updateSlavic, Aida, Overfield, Chris, Riesthuis, Gerhard, Pika, Jiri 12 1900 (has links)
UDC Summary (udcS) is a selection of around 2,000 UDC numbers intended for free use, training and research of the UDC, and is published as an online database at http://www.udcc.org/
udcsummary/php/index.php. This is the first time in the UDC’s history that the scheme has been made available to any extent for free use in so many languages as a single service. By the end of 2009, this abridged scheme was available in 13 languages and at the time of writing this report there are already over 20 languages online. The UDC Summary is available in languages in which the UDC has never been translated before such as Armenian, Greek, and Hindi.

Management of Big Annotations in Relational Database Management SystemsIbrahim, Karim 24 April 2014 (has links)
Annotations play a key role in understanding and describing the data, and annotation management has become an integral component in most emerging applications such as scientific databases. Scientists need to exchange not only data but also their thoughts, comments and annotations on the data as well. Annotations represent comments, Lineage of data, description and much more. Therefore, several annotation management techniques have been proposed to efficiently and abstractly handle the annotations. However, with the increasing scale of collaboration and the extensive use of annotations among users and scientists, the number and size of the annotations may far exceed the size of the original data itself. However, current annotation management techniques don’t address large scale annotation management. In this work, we propose three chapters to that tackle the Big annotations from three different perspectives (1) User-Centric Annotation Propagation, (2) Proactive Annotation Management and (3) InsightNotes Summary-Based Querying. We capture users' preferences in profiles and personalizes the annotation propagation at query time by reporting the most relevant annotations (per tuple) for each user based on time plan. We provide three Time-Based plans, support static and dynamic profiles for each user. We support a proactive annotation management which suggests data tuples to be annotated in case new annotation has a reference to a data value and user doesn’t annotate the data precisely. Moreover, we provide an extension on the InsightNotes: Summary-Based Annotation Management in Relational Databases by adding query language that enable the user to query the annotation summaries and add predicates on the annotation summaries themselves. Our system is implemented inside PostgreSQL.
