Texture advection on discontinuous flows
2015
Texture advection techniques, which transport textures using a velocity field, are used to visualize the dynamics of a flow on a triangle mesh. Some flow phenomena lead to velocity fields with discontinuities that cause the deformation of the texture which is not properly controlled by these techniques. We propose a method to detect and visualize discontinuities on a flow, keeping consistent texture advection at both sides of the discontinuity. The method handles the possibility that the discontinuity travels across the domain of the flow with arbitrary velocity, estimating its speed with least-squares approximation. The technique is tested with different sample scenarios and with two avala…
Context-Aware Visual Exploration of Molecular Datab
2006
Facilitating the visual exploration of scientific data has received increasing attention in the past decade or so. Especially in life science related application areas the amount of available data has grown at a breath taking pace. In this paper we describe an approach that allows for visual inspection of large collections of molecular compounds. In contrast to classical visualizations of such spaces we incorporate a specific focus of analysis, for example the outcome of a biological experiment such as high throughout screening results. The presented method uses this experimental data to select molecular fragments of the underlying molecules that have interesting properties and uses the res…
Does Christian Spirituality Enhance Psychological Interventions on Forgiveness, Gratitude, and the Meaning of Life? A Quasi-Experimental Intervention…
2020
Scientific research has provided theoretical evidence on the implementation of religious/spiritual interventions (RSI) as a complementary health therapy, where spiritual improvements are also a factor to consider. Despite the above, there are few studies that have evaluated the clinical applicability of these findings. This study was an intervention with older and younger adults divided into two treatment groups and one control group. What is expected is that the two treatment groups will score better than the control group
The iconic interface for the PIctorial C language
2003
Iconic environments intend to provide expressive tools to implement, to debug and to execute programs. Moreover its pictorial constructs guide the user to design algorithms in an interactive fashion. Visual interfaces are especially required whenever programs run on an heterogeneous and reconfigurable multiprocessor system oriented to image analysis. Pictorial tools help the user to control the scope of variables, and the distribution of the tasks into the processors. In this paper, the general design, the visual-syntax, and the implementation of the first prototype of an iconic user interface for the PIctorial C Language (PICL) are described. >
A Case of Use in the Management of Administrative Processes, Control of Procedures and Services to Citizens In E-Government
2020
One of the objectives of the fourth industrial revolution is the use of data to make decisions, in this sense the decisions of the government could be better if they are based on useful data sources, with quality and focused on services to citizens. This article presents a case of use in the government of Colombia in which an information system was created for the management of complaints and claims by means of control panels, visualization of statistical information and high personalization in the processes for more than 1200 offices and 8000 employees.
Learning from the Past : The Women Writers Project and Thirty Years of Humanities Text Encoding
2017
In recent years, intensified attention in the humanities has been paid to data: to data modeling, data visualization, “big data”. The Women Writers Project has dedicated significant effort over the past thirty years to creating what Christoph Schöch calls “smart clean data”: a moderate-sized collection of early modern women’s writing, carefully transcribed and corrected, with detailed digital text encoding that has evolved in response to research and changing standards for text representation. But that data—whether considered as a publication through Women Writers Online, or as a proof of the viability of text encoding approaches like those expressed in the Text Encoding Initiative (TEI) Gu…
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…
TBSSvis: Visual Analytics for Temporal Blind Source Separation
2020
Temporal Blind Source Separation (TBSS) is used to obtain the true underlying processes from noisy temporal multivariate data, such as electrocardiograms. TBSS has similarities to Principal Component Analysis (PCA) as it separates the input data into univariate components and is applicable to suitable datasets from various domains, such as medicine, finance, or civil engineering. Despite TBSS’s broad applicability, the involved tasks are not well supported in current tools, which offer only text-based interactions and single static images. Analysts are limited in analyzing and comparing obtained results, which consist of diverse data such as matrices and sets of time series. Additionally, p…
Identifying Geographic Terms within Natural Language Text
2008
Masteroppgave i informasjons- og kommunikasjonsteknologi 2008 – Universitetet i Agder, Grimstad The huge amount of textual data available in digital form in today’s world increases the need for methods that facilitate ease of access and navigability. Automatic extraction of keywords from text bodies is one promising approach. However, the relevance of keywords are context dependent, and extracting relevant keywords often requires a semantic analysis, simply because words may have different meanings in different contexts. It is well-known that resolving such word sense ambiguity automatically can be very challenging. When the topic of interest is geographic information, important keywords wo…
WLAN 802.11 b/g interference into ZigBee networks
2008
Masteroppgave i informasjons- og kommunikasjonsteknologi 2008 – Universitetet i Agder, Grimstad ZigBee network as a low rate wireless personal area network (LR-WPANs) developed very fast nowadays. Since both ZigBee network and WLAN (802.11b/g) operate in the 2.4GHz unlicensed industrial scientific medical (ISM) frequency band, signal interference is possible to exist and result in signal degradation when devices are collocated in the same environment. This thesis analyzes, simulates and measures the interference and evaluates ZigBee network performance under the WLAN interference in terms of Packet Error Rate (PER) and Packet Loss Ratio (PLR). And the investigation emphasis of this thesis i…
