Diagrammes et théorie de la relativité restreinte : une ingénierie didactique / Diagrams and special theory of relativity : a didactic engineeringMoutet, Laurent 30 November 2016 (has links)
Nous avons développé et mis à l’épreuve des activités utilisant un registre basé sur des diagrammes lors de l’enseignement de la théorie de la relativité restreinte avec des élèves de terminale S. L’approche graphique est source de difficultés didactiques mais les potentialités didactiques peuvent être plus avantageuses. Une étude épistémologique sur les diagrammes utilisables en relativité restreinte permet de voir les liens importants entre les mathématiques et la genèse de la théorie. C’est le cas du diagramme de Minkowski. Nous avons également étudié les diagrammes de Brehme et de Loedel, créés beaucoup plus tard pour des raisons didactiques. Après les séances pilotes, nous avons développé un nouveau cadre théorique, permettant d’analyser plus finement les interactions développées par les élèves résolvant un problème utilisant des diagrammes en relativité restreinte. Nous avons modifié les espaces de travail mathématique (ETM) en rajoutant le cadre de rationalité de la physique à celui des mathématiques. Le cadre des ETM étendu nous a permis de concevoir plusieurs versions de séquences et de réaliser une analyse a priori de leur niveau de difficulté et a posteriori en étudiant des travaux d’élèves. L’analyse du travail de groupes d’élèves a été effectuée lors d’une séquence utilisant le diagramme de Minkowski avec GeoGebra, un logiciel de simulation graphique. Le degré de maitrise du diagramme de Minkowski a été évalué pour chaque élève du point de vue des mathématiques et de la physique. Les résultats sont prometteurs, ils montrent une appropriation réelle des concepts de la théorie de la relativité restreinte via une approche utilisant des diagrammes. / We tried to develop and test several activities using a register based on diagrams for teaching the special theory of relativity to S class of twelfth graders. The graphic approach may result it complications in learning. However, its educational potential can turn out to be more beneficial. An epistemological study on diagrams used in special relativity allowed us to report important links between mathematics and the genesis of the special theory of relativity. This is the case of the Minkowski diagram. We were also interested in two other diagrams, Brehme and Loedel, which were developed much more later for teaching purposes. Following experimental sessions, we developed a new theoretical frame to comprehensively analyse the interactions developed by students to solve a problem using diagrams in special relativity. We modified the mathematical working spaces (MWS) by adding a new frame of rationality to the existing mathematic workspace to physics. The extended frame of the MWS allowed us to plan several versions of sequences proposed to the students and realize a priori analysis of their difficulty level and a posteriori study by analysing pupils' works. We have considered several works of student groups during a sequence using the Minkowski diagram with GeoGebra, a graphic simulation software. It allowed us to estimate the degree of control of the Minkowski diagram for every student, both from the frame of rationality of the mathematics and the physical sciences’ point of view. The results are promising and they tend to show a real appropriation of the concepts of the special theory of relativity with an approach using diagrams.

ROZPOZNÁNÍ ČINNOSTÍ ČLOVĚKA VE VIDEU / HUMAN ACTION RECOGNITION IN VIDEOŘezníček, Ivo January 2014 (has links)
Tato disertační práce se zabývá vylepšením systémů pro rozpoznávání činností člověka. Současný stav vědění v této oblasti jest prezentován. Toto zahrnuje způsoby získávání digitálních obrazů a videí společně se způsoby reprezentace těchto entit za použití počítače. Dále jest prezentováno jak jsou použity extraktory příznakových vektorů a extraktory pros- torově-časových příznakových vektorů a způsoby přípravy těchto dat pro další zpracování. Příkladem následného zpracování jsou klasifikační metody. Pro zpracování se obecně obvykle používají části videa s proměnlivou délkou. Hlavní přínos této práce je vyřčená hypotéza o optimální délce analýzy video sekvence, kdy kvalita řešení je porovnatelná s řešením bez restrikce délky videosekvence. Algoritmus pro ověření této hypotézy jest navržen, implementován a otestován. Hypotéza byla experimentálně ověřena za použití tohoto algoritmu. Při hledání optimální délky bylo též dosaženo jistého zlepšení kvality klasifikace. Experimenty, výsledky a budoucí využití této práce jsou taktéž prezentovány.

A Spatio-Temporal Data Model for ZoningUhl, Philip J. 01 January 2002 (has links) (PDF)
Planning departments are besieged with temporal/historical information. While for many institutions historical information can be relegated to archives, planning departments have a constant need to access and query their historical information, particularly their historical spatial information such as zoning. This can be a cumbersome process fraught with inaccuracies due to the changing organizational methods and the extended historical legacies of most municipalities. Geographic Information Systems can be a tool to provide a solution to the difficulties in querying spatio-temporal planning data. Using a data model designed specifically to facilitate the querying of historical zoning information, queries can be performed to answer basic zoning questions such as "what is the zoning history for a specific parcel of land?" This work outlines this zoning data model, its implementation, and its testing using queries basic to the needs of planning departments.

A game engine based application for visualising and analysing environmental spatiotemporal mobile sensor data in an urban contextHelbig, Carolin, Becker, Anna Maria, Masson, Torsten, Mohamdeen, Abdelrhman, Sen, Özgür Ozan, Schlink, Uwe 14 March 2024 (has links)
Climate change and the high proportion of private motorised transport leads to
a high exposure of the urban population to environmental stressors such as
particulate matter, nitrogen oxides, noise, and heat. The few fixed measuring
stations for these stressors do not provide information on how they are
distributed throughout the urban area and what influence the local urban
structure has on hot and cold spots of pollution. In the measurement
campaign “UmweltTracker” with 95 participants (cyclists, pedestrians), data
on the stressors were collected via mobile sensors. The aim was to design
and implement an application to analyse the heterogeneous data sets. In this
paper we present a prototype of a visualisation and analysis application based
on the Unity Game Engine, which allowed us to explore and analyse the
collected data sets and to present them on a PC as well as in a VR
environment. With the application we were able to show the influence of
local urban structures as well as the impact of the time of day on the
measured values. With the help of the application, outliers could be
identified and the underlying causes could be investigated. The application
was used in analysis sessions as well as a workshop with stakeholders.
