Lielapjoma datu vizualizācija

2015

Cilvēkam ir grūti aptvert cik daudz nestrukturēta informācija tiek ģenerēta vienā minūtē, kur nu vēl vienas dienas laikā. Vienas minūtes laikā tiek ģenerēti 250 petabaiti, kas ir apmēram 250 000 terabaitu. Darba mērķis ir sniegt ieskatu lielapjoma datu pasaulē, ko ar lielapjoma datiem ir iespējams paveikt un kā to mēģināt saprast. Darbā ir aprakstīta lielapjoma datu aktualitāte, uzturēšana, analītika un vizualizācija. Kā arī tiek pētīti dati par Paula Stradiņa klīniskās universitātes slimnīcas kardioloģijas nodaļas pacientiem pēdējo 10 gadu laikā. Pateicoties vizualizācijām, tiek konstatēts, ka mūsdienu stereotipiskā domāšana ne vienmēr ir pareiza. Vizualizācijas parāda galvenos sirds un as…

Introducing a new method for efficient visualization of complex shape 3D ultrasonic phased-array C-scans

2017

Automated robotic inspection systems allow the collection of large data volumes, compared to existing inspection systems. To maximize the throughput associated with the non-destructive evaluation phase, it is crucial that the reconstructed inspection data sets are generated and examined rapidly without a loss of detail. Data analysis often becomes the bottleneck of automated inspections. Therefore, new data visualization tools, suitable to screen the NDT information obtained through robotic systems, are urgently required. This paper presents a new approach, for the generation of three-dimensional ultrasonic C-scans of large and complex parts, suitable for application to high data throughput…

Imagery ability and imagery use in individual and team sports

2014

The purpose of this research was to examine whether individual and team sport athletes differ in their imagery use and imagery ability, and to examine whether level of sport participation or weekly sport involvement are variables that differentiate between athletes on the basis of their levels of imagery ability and imagery use. Two measures were conducted. The Sport Imagery Ability Measure (SIAM) is a 48-item self-report measure that uses four sport related scenes to examine the dimensional, sensorial, and emotional characteristics of generating images. The Sport Imagery Questionnaire (SIQ) is a 30-item self-report measure that examines five characteristics associated with the cognitive an…

3D Matrix-Based Visualization System of Association Rules

2017

With the growing number of mining datasets, it becomes increasingly difficult to explore interesting rules because of the large number of resultant and its nature complexity. Studies on human perception and intuition show that graphical representation could be a better illustration of how to seek information from the data using the capabilities of human visual system. In this work, we present and implement a 3D matrix-based approach visualization system of association rules. The main visual representation applies the extended matrix-based approach with rule-to-items mapping to general transaction data set. A novel method merging rules and assigning weight is proposed in order to reduce the …

La visualisation au service de l'analyse d'interactions Implémentation d'une forme de visualisation générique au sein d'un environnement d'analyse de…

2009

International audience; La visualisation de traces d'interactions est une composante importante de leur analyse dans le cadre de l'évaluation d'usages d'EIAH collaboratifs. Différentes présentations permettent en effet aux chercheurs de plus facilement explorer des corpus parfois très complexes. Dans cet article, nous examinons les besoins de chercheurs désirant visualiser et analyser des traces d'interaction et introduisons la notion de partition d'interaction, une forme générique de visualisation adaptée à ces besoins. Nous montrons de quelle manière cette fonction a été implémentée au sein de Tatiana, un environnement d'analyse de traces. En particulier, nous illustrons comment l'archite…

Proposition méthodologique pour l'exploration et la visualisa- tion des données de mobilité

2017

National audience; Les sources de données de mobilité individuelle se sont aujourd’hui très diversifiées, aussi bien du côté des outils de collecte (smartphones, objets connectés, capteurs) que de celui d’applications (applications téléphoniques, simulation spatiale). Ces données partagent en général le fait d’être désagrégées et multidimensionnelles : elles se caractérisent par des attributs à la fois spatiaux (localisation, géométrie), thématiques (motif, mode de déplacement) et temporels (heure de début et de n, durée) qui décrivent les déplacements des individus (Peuquet D., 1994).

Modes de représentation des trajectoires quotidiennes des habitants

2007

Representing the daily trajectories of individuals Current research on inhabitants' daily mobilities has confirmed that individual mobility strategies are based on activity programmes. In France, the Household Travel Survey (HTS) is one of the principal sources of information about individual travel behaviour. Despite some drawbacks, they are rich sources of spatio-temporal data, as well as providing information on individual and household characteristics. However, for daily mobilities to be analysed, the raw data need to be reorganized. This study is based on the Grenoble-area Household Travel Survey, carried out in 2002. We propose to explore the HTS data through examples of individual mo…

iHERITAGE Project : AR/VR for the enhancement and accessibility of the norman architecture of the Unesco site of Palermo

2023

In the context of conservation and dissemination of cultural heritage, noninvasive technologies for the generation of digital models have produced exponential growth in the quality of the data acquired. The digital contents processed allow the use of architectural contexts that no longer exist or sites that are di cult to access, thanks to the visualisation of high-resolution and immersive products. However, the process from acquisition to visualisation requires optimisation strategies and specific operational choices, depending on the design goals. The study describes some results of a broader research within the iHERITAGE Project funded by the ENI CBC MED Program 2014-2020, critically des…

Information retrieval in digital documents : towards a variation of procedure patterns

2013

The research activity of information on the internet has become common in our daily life. Despite this fact, it still raises many problems for the user who does not find the information they want or is lost to the amount of information available. This study aims at testing a new patented preview device, enabling users to browse and view pages in depth. The task is to find a target apartment with one or more specific criteria in a real estate agency designed website. Several conditions were tested. The “usual” condition with the classic search features, page by page, the other "transparent" condition which enables you to preview selected pages and select only relevant pages. We are intereste…
