Full textFör att kunna förstå och ta ställning till utmaningar i form av exempelvis klimatförändringar, förlust av biodiversitet och antibiotikaresistens krävs kunskap om evolution. För att förstå evolution är det i sin tur viktigt att inse betydelsen av de tidsskalor som evolutionära processer omfattar. Detta utgör inte sällan ett problem vid undervisning om evolution eftersom det rör sig om tidsskalor som sträcker sig långt bortom vad vi själva kan erfara. Tidsskalor ingår i en grupp av begrepp som kallas tröskelbegrepp. Tröskelbegrepp utmärks av att de är svåra att ta till sig, men när väl förståelse uppnås så innebär det en radikal och permanent förändring av hur ett ämnesinnehåll, exempelvis evolution, betraktas. Av den anledningen är de också ”enkelriktade” i meningen att den nya förståelsen är bestående Ett sätt att bemöta problemen med att förstå tidsskalor av varierande storlekar är att använda dynamiska visualiseringar. Denna avhandling handlar just om hur elevers förståelse av evolution med avseende på tiden kan underlättas genom visualiseringar i undervisning. Avhandlingen baseras på två studier som var och en belyser evolutionär tid på olika sätt beträffande såväl innehåll som form. I den första studien undersöktes hur olika varianter av en tidsrepresentation i form av animerade tidslinjer påverkade 144 studenters förståelse av olika tidsaspekter. Representationen av tid hade två variabler, nämligen antal tidslinjer (en tidslinje respektive 3 tidslinjer med olika skalor) och hastighet för animationen av tidsförloppet (konstant hastighet respektive avtagande hastighet när animationen närmade sig nutid). De två variablerna kombinerades för att ge fyra olika varianter av tidsrepresentation. I studien jämfördes varianterna genom att undersöka studenters förmåga kring olika tidsaspekter; hitta händelser vid specifika tider, uppfatta ordning på händelser, uppfatta samtidiga händelser, uppfatta längden på ett tidsintervall och jämföra längden av två tidsintervall. I den andra studien undersöktes uppfattningar och förståelse av tidsmässiga aspekter hos 10 gymnasieelever med utgångspunkt från det interaktiva multi-touch-bordet ”DeepTree”. Det är en interaktiv visualisering av livets träd, det vill säga de fylogenetiska sambanden mellan organismer på jorden. I denna studie fokuserades de interaktiva aspekterna av visualiseringen, särskilt kring hur zoomfunktionen uppfattades av elever men också vilka missuppfattningar som var kopplade till interaktioner. Även tidsaspekterna från den första studien undersöktes. Resultaten från den första studien visar att det under vissa omständigheter kan vara en fördel att variera det animerade tidsflödet, till exempel genom att hastigheten på tidsflödet i animationen avtar under en speciellt händelserik period som behöver granskas noggrannare. Under andra omständigheter kan det däremot vara olämpligt att variera hastigheten för den animerade tiden eftersom det försvårar bedömningen av storleken på, och jämförelsen av, tidsintervall. Det är alltså viktigt att lärare är medvetna om vilken, eller vilka, tidsaspekter som är centrala i den specifika lärandesituationen. Resultaten från den andra studien visar två olika sätt att uppfatta zoomfunktionen när den används i applikationen DeepTree; antingen som en rörelse i tid eller som en rörelse i det metaforiska trädet. Flera missuppfattningar av interaktionen observerades hos eleverna. Till exempel tolkade en del elever den tid det tog att zooma i trädet som att det motsvarade hur lång tid som förflöt mellan olika evolutionära händelser. Ett antal elever verkade anta att det finns en implicit linjär tidslinje längs y-axeln på trädet, och att ju fler grendelningar som fanns längs en gren desto längre tid motsvarade grenen. Generellt är de flesta tidsaspekter svåra att uppfatta för användare av DeepTree. Evolutionära träd av denna typ är dock främst gjorda för att illustrera släktskapsförhållanden, men de tidsmässiga aspekterna skulle kunna förbättras. Applikationer av den typ som DeepTree utgör har potential att erbjuda goda möjligheter till lärande även beträffande evolutionär tid men hänsyn behöver då tas just till hur tidsaspekter beskrivs.

Full textThis study deals with the use of 3D-dynamic visualizations for teaching complex molecular cell biology concepts. The focus is on signal transduction, which is a concept that constitutes an important part of biological systems. 3D-dynamic visualizations (animations) were produced and shown for a total of 24 students attending a course in molecular cell biology at Karlstad University, Sweden. Data were collected by questionnaires and interviews which were structured around the understandability and usefulness of the animations. The results indicate that animations are useful for teaching life science concepts and can serve as a complement to lectures. They are useful for visualizing continuous time-dependent processes like signal transduction chains. Several connections between students' issues of understanding and layout-issues of the animations were established. A number of implications follow from the study. Basic understanding of animations is fundamental for understanding of advanced concepts, which should be kept in mind in the design phase of production. The level of realism of different factors in animations, like molecule speed and distances, has to be set to strike a balance between conceptual understanding and scientific correctness. Visualization of 3D-structure of molecules provides an understanding of molecule and systemic function. The study reinforces the need to use visualizations in life science teaching.
Denna studie behandlar användningen av 3D-dynamiska visualiseringar för att lära ut komplexa koncept i molekylär cellbiologi. Fokus är på signalöverföring, vilket är ett koncept som är en viktig del av biologiska system. 3D-dynamiska visualiseringar producerades och visades för totalt 24 studenter närvarande på en kurs i molekylär cellbiologu vid Karlstad Universitet, Sverige. Data samlades genom frågeformulär och intervjuer strukturerade runt förståelse och användning av animeringarna. Resultaten indikerar att animeringar är användbara för att lära ut koncept inom livsvetenskap och kan vara ett komplement till lektioner. De är användbara för att visualisera kontinuerliga tidsberoende processer som signalöverföringskedjor. Flera kopplingar mellan frågeställningar för studenternas förståelse och layout-frågeställningar för animeringarna fastställdes. Studien medför ett antal följder. Grundläggande förståelse av animeringar är fundamentalt för förståelse av avancerade koncept, vilket ska betänkas vid designfasen av produktion. Nivån av realism av olika faktorer i animeringarna, som molekylhastighet och avstånd, måste sättas för få balans mellan konceptuell förståelse och vetenskaplig riktighet. Visualisering av molekylers 3D-struktur ger förståelse av molekyl och systemisk funktion. Studien stärker behovet av att använda visualisering i undervisning av livsvetenskap.

Full textDoctor of Philosophy
In this work, two main ideas in data visualization and anomaly detection in dynamic networks are further explored. For both ideas, a connecting theme is extensions of a method called Multidimensional Scaling (MDS). MDS is a dimension-reduction method that takes high-dimensional data (all $p$ dimensions) and creates a low-dimensional projection of the data. That is, relationships in a dataset with presumably a large number of dimensions or variables can be summarized into a lower number of, e.g., two, dimensions. For a given data, an analyst could use a scatterplot to observe the relationship between 2 variables initially. Then, by coloring points, changing the size of the points, or using different shapes for the points, perhaps another 3 to 4 more variables (in total around 7 variables) may be shown in the scatterplot. An advantage of MDS (or any dimension-reduction technique) is that relationships among the data can be viewed easily in a scatterplot regardless of the number of variables in the data. The interpretation of any MDS plot is that observations that are close together are relatively more similar than observations that are farther apart, i.e., proximity in the scatterplot indicates relative similarity. In the first project, we use a weighted version of MDS called Weighted Multidimensional Scaling (WMDS) where weights, which indicate a sense of importance, are placed on the variables of the data. The problem with any WMDS plot is that inaccuracies of the method are not included in the plot. For example, is an observation that appears to be an outlier, really an outlier? An analyst cannot confirm this without further context. Thus, we created a model to calculate, visualize, and interpret such inaccuracy or uncertainty in WMDS plots. Such modeling efforts help analysts facilitate exploratory data analysis. In the second project, the theme of MDS is extended to an application with dynamic networks. Dynamic networks are multiple snapshots of pairwise interactions (represented as edges) among a set of nodes (observations). Over time, changes may appear in some of the snapshots. We aim to detect such changes using a process monitoring approach on dynamic networks. Statistical monitoring approaches determine thresholds for in-control or expected behavior that are calculated from data with no signal. Then, the in-control thresholds are used to monitor newly collected data. We applied this approach on dynamic network data, and we utilized a detailed simulation study to better understand the performance of such monitoring. For the simulation study, data are generated from dynamic network models that use MDS. We found that monitoring summary statistics of the network were quite effective on data generated from these models. Thus, simple tools may be used as a first step to anomaly detection in dynamic networks.

Abdelsadek, Youcef. "Triangle packing for community detection : algorithms, visualizations and application to Twitter's network." Thesis, Université de Lorraine, 2016. http://www.theses.fr/2016LORR0310.
Full textRelational data in our society are on a constant increasing, rising arduous challenges. In this thesis, we consider two aspects of relational data. First, we are interested in relational data with weighted relationship. As a concrete example, relationships among Twitter's users could be weighted with regard to their shared number of followers. The second aspect is related to the dynamism which is inherent to data nature. As an instance, in the previous example the number of common followers between two Twitter's users can change over time. In order to handle these complex and dynamic relational data, we use the modelling strength of graphs. Another facet considered in this thesis deals with community identification on weighted and dynamic graphs. For an analyst, the community detection might be helpful to grasp the semantic behind the graph structure. Our assumption relies on the idea to use a set of disjoint pairwise triangles as a basis to detect the community structure. To select these triangles, several algorithms are proposed (i.e., branch-and-bound, greedy search, heuristics and genetic algorithm). Thereafter, we propose a community detection algorithm, called Tribase. In the latter, the weights of communities are compared allowing dominant communities to gain in size. Tribase is compared with the well-known LFR benchmark. The results show that Tribase identifies efficiently the communities while a community structure exists. Additionally, to asset Tribase on real-world data, we consider social networks data, especially Twitter's data, of the ANR-Info-RSN project. In order to support the analyst in its knowledge acquisition, we elaborate a visual interactive approach. To this end, an interactive application, called NLCOMS is introduced. NLCOMS uses multiple synchronous views for visualizing community structure and the related information. Furthermore, we propose an algorithm for the identification of communities over time, called Dyci. The latter takes advantage from the previously detected communities. Several changes' scenarios are considered like, node/edge addition, node/edge removing and edge weight update. The main idea of the proposed algorithm is to track whether a part of the weighted graph becomes weak over time, in order to merge it with the "dominant" neighbour community. In order to assess the quality of the returned community structure, we conduct a comparison with a genetic algorithm on real-world data of the ARN-Info-RSN project. The conducted comparison shows that Dyci algorithm provides a good trade-off between efficiency and consumed time. Finally, the dynamic changes which occur to the underlying graph structure can be visualized with NLCOMS which combines physical an axial time to fulfil this need

Full textThe use of dynamic visualizations such as animations, videos and virtual reality for training and improving athletes’ performance in the sport field and, particularly in soccer, keeps growing. However, the instructional effectiveness of these informationenriched supports according to learners' characteristics remains not yet fully exploited. While some characteristics such as athletes’ expertise have been widely studied, other characteristics such as individuals' visuospatial abilities (VSA) have received little attention so far and are still neglected. With the aim to improve communication and learning sessions using dynamic visualizations this thesis aims at examining the effect of VSA, expertise and instruction design on the memorization of dynamic soccer tactics. The main results revealed that: (i) participants (experts and novices) with high-VSA were better-equipped than participants with low-VSA to memorize tactical plans from dynamic visualizations. (ii) novices benefited more from VSA than experts, confirming that VSA become less important when learners' prior knowledge increases. (iii) increasing the level of realism or dynamism of dynamic visualizations hindered tactical learning effectiveness, especially for learners with low-VSA. Results urge sport stakeholders to consider VSA in addition to the level of expertise and to select the appropriate instructional design to optimize learning from dynamic visualizations in team sports

Full textScania CV AB’s modulära produktsystem medför möjligheten till komplett lastbilsanpassning samtidigt som endast ett begränsat antal utbytbara komponenter används. Den höga produktmodulariteten ställer höga krav på kvalitetssäkring av de levererade produkterna. Geometri och layoutsäkring är en nyckelfaktor inom säkerhetställandet av kvaliteten. Dynamisk geometrisäkran av lastbilar utförs genom att mäta rörelser av vissa komponenter under fysiska provningar. Resultaten analyseras sedan för att säkerställa att inga oönskande kollisioner inträffar under drift av fordonet. Provresultaten presenteras i provningsrapporter i form av 2D-plottar visande deltarörelser som inträffat vid specifika mätpunkter. Provningsrapporter anses vara svårtolkade och konstruktionsmisstag har inträffat på grund av feltolkningar av dessa. Syftet med examensarbetet var att utveckla en 3D-visualiseringsmetod som kan komplettera provningsrapporter och underlätta förståelsen av provresultaten. I detta examensarbete har flera visualiseringsmetoder identifierats. De identifierade visualiseringsmetoderna utvärderades sedan enligt krav härledda från intervjuer som hölls på Scania. En metod valdes därefter för vidare utveckling. Examensarbetet inriktades mot visualisering av hyttrörelser. Målet med utvecklingen var dock att skapa en generell metod för rörelser av alla huvudkomponenter, som till exempel axlar och motor. Resultatet av utvecklingen var en visualiseringsmetod som inkluderade ett MATLAB-script samt ett CATIA-makro. MATLAB-scriptet filtrerar råtestdata för extrema positioner av hytten. Dessa positioner räknas sedan om som transformationsmatriser och exporteras til ett Excel-ark. Excel-arket importeras sedan av CATIA-makrot till CATIA, som instansierar och positionerar användarvalda komponenter i de tidigare hittade extrempositionerna. Den utvecklade visualiseringsmetoden verifieras sedan och det bekräftas att tillförlitliga resultat fås fram. Dessutom diskuteras fördelarna och nackdelarna med visualiseringmetoden. Den utvecklade visualiseringsmetoden utvärderas sedan med de tidigare ställda kraven. Utvärderingen visar att dessa uppfylls. Även om ytterligare verifiering av visualiseringsmetoden föreslås, dras slutsatsen att metoden kan och bör implementeras i det aktuella arbetsflödet.

Full textThis thesis presents a visualization framework designed to address these issues. The framework is based on a new, extensible language called JIL which provides a common format for encapsulating intermediate representations and associating them with compile-time and runtime data. We present new contributions which extend existing compiler and profiling frameworks, allowing them to export the intermediate languages, analysis results, and code metadata they collect as JIL documents. Visualization interfaces can then combine the JIL data from separate tools, exposing both static and dynamic characteristics of the underlying code. We present such an interface in the form of a new web-based visualizer, allowing JIL documents to be visualized online in a portable, customizable interface.

Dynamic analysis, which involves gathering information about a program as it is executing, is becoming increasingly common as reverse engineers attempt to more efficiently analyze complex software systems. In this thesis, I implement a technique called dynamic slicing, which determines how values in a program's register or memory, such as strings, are computed as a function of the program's initial state. This technique is then evaluated on sets of programs of interest to reverse engineers: string generation and string encoding/decoding algorithms. A common source of these algorithms is malware, which often employs these mechanisms to obfuscate and to make human-driven reverse engineering more difficult. In particular, malware will use Domain Generation Algorithms (DGAs) to construct seemingly randomized domain names to contact their control servers. We demonstrate that metrics and graphs produced with dynamic slicing can be successfully employed on these algorithm classes, elucidating interesting features from different families of malware and reducing the manual workload of malware reverse engineers.

The visual expression of architectural ideas, specifically in the preliminary stages of design, has generally been by means of static images on two dimensional surfaces. Our perception of a building or an urban context compared to what actually is communicated by most visual tools, indicates to us that most representation media lack an essential quality, that of movement. Not until recently were we able to introduce this quality within our methods of representation. Computer graphics as a new tool for visual expression can provide us with the means to examine spatial ideas dynamically. This can increase an observer's understanding and enable designers to manipulate their ideas in a more reactive and dynamic environment. This thesis will examine the more conventional media used to convey form and space, and discuss the advantages and disadvantages associated with them. The central issue to this thesis is the aspect of movement: that motion is an essential part of spatial understanding and that of visual perception. As a base for my arguments I have chosen some theories of perception relevant to architecture, and tried to find parallels which could give rise to a better understanding of architectural form and space and to it's representation. Finally, I have looked at the state of the art in computer graphics: the difficulties involved in creating computer images, how they are being overcome and lastly the potential for visualization that computers can offer in the future.

Full textData structure usage has been the target of various static techniques. Static approaches, however, may suffer from reduced accuracy in complex situations and have the potential to be overly-conservative in their approximation. An accurate, clean picture of runtime heap activity is difficult to achieve.
We have designed and implemented a dynamic heap analysis system that allows one to examine and analyze how Java programs build and modify data structures. Using a complete execution trace from a profiled run of the program, we build an internal representation that mirrors the evolving runtime data structures. The resulting series of representations can then be analyzed and visualized. This gives us an accurate representation of the data structures created and an insight into the program's behaviour. Furthermore we show how to use our approach to help understand how programs use data structures, the precise effect of garbage collection, and to establish limits on static data structure analysis.
A deep understanding of dynamic data structures is particularly important for modern, object-oriented languages that make extensive use of heap-based data structures. These analysis results can be useful for an important group of applications such as parallelization, garbage collection optimization, program understanding or improvements to other optimization.

Information visualizations, especially those utilizing web-based platforms, are becoming an increasingly common medium for exchanging ideas. This emergent class of tools enabling web-based, interactive platforms for visualizing data should be considered by urban planners and designers as an opportunity to create new modes of disseminating and communicating information. This thesis provides an overview of new visualization tools: how they are being developed and combined, their applications, and their potential future uses. It also explores the implications of such tools in contexts where technology is not yet mainstream. This is illustrated through a case study of using mobile phones to gather data on the bus system in Dhaka, Bangladesh. The research draws from literature written on critical cartography, visualization, and visual culture in urban design and planning. The work first develops a best practices workflow of existing and emerging visualization tools and platforms. It then constructs prototypes of products for various audiences that illustrate the outputs of data collected on Dhaka's bus system, showcasing the potentials of these new tools and platforms.

Social patterns are observable in real-world interactions as visual cues. Online, however, there are few visual cues available that can be used to see and understand social patterns. In this thesis, I suggest that many of these social patterns are still present in our interactions online in text chat; they are merely encoded in the textual interactions. This thesis presents Coterie, a visualization of the conversational dynamics of an Internet Relay Chat (IRC) channel. Through Coterie, viewers can see the social patterns that underlie the text interactions between conversants. Using the chat messages posted to an IRC channel by users, Coterie builds statistical models for individual and channel-level interaction based on existing real-world sociometric models. Coterie also automatically separates out conversations using a conversation model based on a word usage algorithm. This information is then presented to the viewer through a novel display based on models for real-world small group interaction, which allows the viewer to see historical patterns of user interaction, such as a user's verbosity, as well as channel-level patterns, such as cohesiveness. The visualization is evaluated based on how well it makes such patterns visible, and further directions for its development are presented.

Full textThis project presents the research on software visualization techniques. We will introduce the concepts of software visualization, software metrics and our proposed visualization techniques: Static Visualization (glyphs object with static texture) and Dynamic Visualization (glyphs object with moving object). Our intent to study the existing visualization techniques for visualization of software
metrics and then proposed the new visualization approach that is more time efficient and easy to perceive by viewer. In this project, we focus on the practical aspects of visualization of multivariate dataset. This project also gives an implementation of proposed visualization techniques of software metrics. In this research based work, we have to compare practically the proposed visualization approaches. We will discuss the software development life cycle of our proposed visualization system, and we will also describe the complete software implementation of implemented software.

This thesis describes a framework for collecting, analyzing, and visualizing dynamic data, particularly data gathered through Web questionnaires. The framework addresses challenges such as promoting user participation, handling missing or invalid data, and streamlining the data interpretation process. Tools in the framework provide an intuitive way to build robust questionnaires on the Web and perform on-the-fly analysis and visualization of results. A novel 2.5-dimensional dynamic response-distribution visualization allows subjects to compare their results against others immediately after they have submitted their response, thereby encouraging active participation in ongoing research studies. Other modules offer the capability to quickly gain insight and discover patterns in user data. The framework has been implemented in a multi-tier architecture within an open-source, Java-based platform. It is incorporated into Risk Psychology Network, a research and educational project at MIT's Laboratory for Financial Engineering.

Full textWith the growing popularity of GitHub, the largest host of source code and collaboration platform in the world, it has evolved to a Big Data resource offering a variety of Open Source repositories (OSR). At present, there are more than one million organizations on GitHub, among them Google, Facebook, Twitter, Yahoo, CRAN, RStudio, D3, Plotly and many more. GitHub provides an extensive REST API, which enables scientists to retrieve valuable information about the software and research development life cycles. Our research pursues two main objectives: (I) provide an automatic OSR categorization system for data science teams and software developers promoting discoverability, technology transfer and coexistence; (II) establish visual data exploration and topic driven navigation of GitHub organizations for collaborative reproducible research and web deployment. To transform Big Data into value, in other words into Smart Data, storing and processing of the data semantics and metadata is essential. Further, the choice of an adequate text mining (TM) model is important. The dynamic calibration of metadata configurations, TM models (VSM, GVSM, LSA), clustering methods and clustering quality indices will be shortened as "smart clusterization". Data-Driven Documents (D3) and Three.js (3D) are JavaScript libraries for producing dynamic, interactive data visualizations, featuring hardware acceleration for rendering complex 2D or 3D computer animations of large data sets. Both techniques enable visual data mining (VDM) in web browsers, and will be abbreviated as D3-3D. Latent Semantic Analysis (LSA) measures semantic information through co-occurrence analysis in the text corpus. Its properties and applicability for Big Data analytics will be demonstrated. "Smart clusterization" combined with the dynamic VDM capabilities of D3-3D will be summarized under the term "Dynamic Clustering and Visualization of Smart Data via D3-3D-LSA".

Full textVisualization is the process of constructing methods, which are able to synthesize interesting and informative images from data sets, to simplify the process of interpreting the data. In this thesis a new approach to construct meteorological visualization methods using neural network technology is described. The methods are trained with examples instead of explicitely designing the appearance of the visualization.
This approach is exemplified using two applications. In the fist the problem to compute an image of the sky for dynamic weather, that is taking account of the current weather state, is addressed. It is a complicated problem to tie the appearance of the sky to a weather state. The method is trained with weather data sets and images of the sky to be able to synthesize a sky image for arbitrary weather conditions. The method has been trained with various kinds of weather and images data. The results show that this is a possible method to construct weather visaualizations, but more work remains in characterizing the weather state and further refinement is required before the full potential of the method can be explored. This approach would make it possible to synthesize sky images of dynamic weather using a fast and efficient empirical method.
In the second application the problem of computing synthetic satellite images form numerical forecast data sets is addressed. In this case a mode is trained with preclassified satellite images and forecast data sets to be able to synthesize a satellite image representing arbitrary conditions. The resulting method makes it possible to visualize data sets from numerical weather simulations using synthetic satellite images, but could also be the basis for algorithms based on a preliminary cloud classification.
