VisIVO - Integrated Tools and Services for Large-Scale Astrophysical Visualization
VisIVO is an integrated suite of tools and services specifically designed for
the Virtual Observatory. This suite constitutes a software framework for
effective visual discovery in currently available (and next-generation) very
large-scale astrophysical datasets. VisIVO consists of VisiVO Desktop - a stand
alone application for interactive visualization on standard PCs, VisIVO Server
- a grid-enabled platform for high performance visualization and VisIVO Web - a
custom designed web portal supporting services based on the VisIVO Server
functionality. The main characteristic of VisIVO is support for
high-performance, multidimensional visualization of very large-scale
astrophysical datasets. Users can obtain meaningful visualizations rapidly
while preserving full and intuitive control of the relevant visualization
parameters. This paper focuses on newly developed integrated tools in VisIVO
Server allowing intuitive visual discovery with 3D views being created from
data tables. VisIVO Server can be installed easily on any web server with a
database repository. We discuss briefly aspects of our implementation of VisiVO
Server on a computational grid and also outline the functionality of the
services offered by VisIVO Web. Finally we conclude with a summary of our work
and pointers to future developments
An integrated visualization environment for the virtual observatory: Current status and future directions
Visual exploration and discovery applications are invaluable tools to provide prompt and intuitive insights into the intrinsic data characteristics of modern astronomy and astrophysics datasets. Due to the massively large and highly complex datasets, various technical challenges are involved to reach, e.g. interactivity, integration, navigation and collaboration. This paper describes a number of approaches to address these challenges, and focuses on the current status of VisIVO (Visualization Interface for the Virtual Observatory) concentrating on the provided tools ranging from a desktop application to a science gateway and a mobile application. We emphasize the latest developments made in the context of past and current international European funded projects and highlight planned future developments towards further integration within the framework of the Virtual Observatory
The Role of Computational Fluid Dynamics in the Management of Unruptured Intracranial Aneurysms: A Clinicians' View
Objective. The
importance of hemodynamics in the
etiopathogenesis of intracranial aneurysms (IAs)
is widely accepted. Computational fluid dynamics
(CFD) is being used increasingly for hemodynamic
predictions. However, alogn with the continuing
development and validation of these
tools, it is imperative to collect
the opinion of the clinicians.
Methods. A workshop on CFD was
conducted during the European Society of
Minimally Invasive Neurological Therapy (ESMINT)
Teaching Course, Lisbon, Portugal.
36 delegates, mostly clinicians,
performed supervised CFD analysis for an IA, using the
@neuFuse software developed within the European
project @neurIST. Feedback on the workshop was
collected and analyzed. The
performance was assessed on a scale of 1 to 4
and, compared with experts' performance.
Results. Current dilemmas in
the management of unruptured IAs remained the
most important motivating factor to attend the
workshop and majority of participants showed interest in participating in a
multicentric trial. The participants achieved
an average score of 2.52 (range 0–4) which was 63% (range 0–100%) of an expert user. Conclusions.
Although participants showed a manifest interest
in CFD, there was a clear
lack of awareness concerning the role of
hemodynamics in the etiopathogenesis of IAs and
the use of CFD in this context. More efforts
therefore are required to enhance understanding of the
clinicians in the subject
Particularities of visualisation of medical and wellness data through a digital patient avatar
In this work particularities of visualisation of medical and wellness data through a digital patient avatar are given from a standpoint of a proposed approach, under which data for a visualisation may be obtained from a variety of sources through defined interfaces, while end-user interfaces of distinct complexity and level of immersion into the model may be exposed to different categories of users. A short introduction of important medical data exchange standards, specifications and models is offered. A brief overview of projects relevant to a subject of this work is given. The proposed approach is presented along with examples of use-cases
Planck LFI DPC – Configuration Items List
Version 1.0 reviewed by ESA at the Planck SGS Implementation Review (2006)
Version 1.1 reviewed by ESA at the Planck SGS Readiness Review (2008)This document provides information on “as designed” and “as built” configuration items relative to S/W and H/W in the preparation of the LFI DPC. For S/W, it contains information at the level of DPC Level and module: each software configuration item (source, object, executable) is listed together with build instructions, used tools (with their version), and input/output parameters lists, applicable requirement documents, list of all raised and incorporated software SPRs/RIDs. For H/W, it contains information on each hardware configuration item
Planck LFI DPC-DPC SGS1 and SGS2 Flag Mask
The purpose of this Technical Note is to define the Flag mask to be applied at the level of SGS1 and
SGS2 for the DPC purposes. A table on which flag of this general flag mask will be exported in the
EFDD format will be summarized in the last chapter
