Environmental Disasters Data Management Workshop Report

The Environmental Disasters Data Management (EDDM) project seeks to foster communication between collectors, managers, and users of data within the scientific research community, industry, NGOs, and government agencies, with a goal to identify and establish best practices for orderly collection, storage, and retrieval. The Coastal Response Research Center (CRRC) is assisting NOAA’s Office of Response and Restoration (ORR) with this effort. The objectives of the EDDM project are to: Engage the community of data users, data managers, and data collectors to foster a culture of applying consistent terms and concepts, data flow, and quality assurance and control; Provide oversight in the establishment and integration of foundational, baseline data collected prior to an environmental event, based on user requirements; Provide best‐practice guidance for data and metadata management; Suggest infrastructure design elements to facilitate quick and efficient search, discovery, and retrieval of data; Define the characteristics of a “gold standard” data management plan for appropriate data sampling, formatting, reliability, and retrievability; and Deliver workshop conclusions to end users in order to promote the use of the protocols, practices, or recommendations identified by participants

Multidimensional modeling and analysis of large and complex watercourse data: an OLAP-based solution

International audienceThis paper presents the application of Data Warehouse (DW) and On-Line Analytical Processing (OLAP) technologies to the field of water quality assessment. The European Water Framework Directive (DCE, 2000) underlined the necessity of having operational tools to help in the interpretation of the complex and abundant information regarding running waters and their functioning. Several studies have exemplified the interest in DWs for integrating large volumes of data and in OLAP tools for data exploration and analysis. Based on free software tools, we propose an extensible relational OLAP system for the analysis of physicochemical and hydrobiological watercourse data. This system includes: (i) two data cubes; (ii) an Extract, Transform and Load (ETL) tool for data integration; and (iii) tools for OLAP exploration. Many examples of OLAP analysis (thematic, temporal, spatiotemporal, and multiscale) are provided. We have extended an existing framework with complex aggregate functions that are used to define complex analysis indicators. Additional analysis dimensions are also introduced to allow their calculation and also for purposes of rendering information. Finally, we propose two strategies to address the problem of summarizing heterogeneous measurement units by: (i) transforming source data at the ETL tier, and (ii) introducing an additional analysis dimension at the OLAP server tier

Development of a model based on virtual reality for the evaluation of behavioral compliance with warnings and wayfinding contexts

Virtual Reality (VR) when framed in adequate methodologies, has an ample field of application for Ergonomics and for Design, since it allows to analyze and understand how people interaction with simulated situations in Virtual Environments (VEs). As such, it is of extreme importance for research and the practice of Ergonomics, to understand how it is possible to optimize, create, implement and evaluate solutions based in VEs in different contexts, including dangerous one, in particular those that can place in risk the physical integrity of people. These VEs can be used to study the Human behavior in critical situations, which is important when projecting products and systems that involve dangers to the users that would be difficult to study otherwise. In this context, this project has as its general objective the study of the factors that influence the development of VEs for VR and in the implementation of solutions (with a focus on the software and hardware) that better can correspond to the development of this type of studies, namely in studies of behavioral compliance with warnings and in studies of wayfinding. The methodological proposal described in this document focuses in a User-Centered Design (UCD) perspective, which involved the participation of the users, in the different phases of development of the project. As a result, it was developed and evaluated software and hardware solutions for the understanding and evaluation of the factors associated to the study of Human behavior, namely in behavioral compliance with warnings and in wayfinding contexts. It was also studied the best solutions for interaction and navigation in VEs, that correspond to high levels of presence, which is a fundamental aspect in behavioral compliance with warnings and wayfinding studies that use VR as a support tool. With this purpose, two navigational interfaces were developed (i.e., Balance Board and Walk-in-Place), also in a UCD perspective, to guarantee a constant cycle of tests and improvement of the implementations among the users. A comparative study was made between these two navigational interfaces and another that is commonly used in studies with VR (i.e., a Joystick). This comparative study was conducted in a context of evaluation of behavioral compliance with warnings and performance variables were analyzed, as well as the levels of presence in the different navigational interfaces. There were no statistically significant differences in the levels of presence or in the behavioral compliance between the three navigational interfaces. However, statistically significant differences were found in several performance variables (e.g., average speed, total distance). Future directions for the research are also discussed.A Realidade Virtual (RV) quando enquadrada em metodologias adequadas, tem um campo de aplicação alargado para a Ergonomia e o Design, visto permitir analisar e compreender como as pessoas interagem com situações simuladas em Ambientes Virtuais (AVs). Desta forma, é de extrema importância para a investigação ou prática da Ergonomia, perceber como se pode optimizar, construir, implementar e avaliar soluções baseadas em AVs em diferentes contextos, incluindo contextos perigosos, particularmente aqueles que podem colocar em risco a integridade física das pessoas. Estes AVs podem ser usados para estudar o comportamento Humano em situações críticas, o que é importante quando se projecta produtos e sistemas que envolvam perigos para os utilizadores que de outra forma seria muito difícil avaliar. Neste contexto, este projecto tem como objectivo geral o estudo dos factores que influenciam o desenvolvimento de ambientes para Realidade Virtual e na implementação de soluções (com um foco maior no software e hardware) que melhor possam corresponder ao desenvolvimento deste tipo de estudos, nomeadamente em estudos de consonância comportamental com avisos de segurança e estudos de wayfinding. A proposta metodológica descrita neste documento foca-se numa perspectiva de Design Centrado no Utilizador (DCU), que envolveu a participação dos utilizadores, nas várias fases de desenvolvimento do projecto. Como resultado, desenvolveu-se e avaliou-se soluções de software e hardware para a compreensão e avaliação dos factores associados ao estudo do comportamento Humano, nomeadamente para a consonância comportamental com avisos de segurança e para situações de wayfinding. Foram também estudadas as melhores soluções para interacção e navegação em AVs, que correspondam a níveis de presença elevados, aspecto fundamental em estudos de consonância comportamental com avisos de segurança e em estudos de wayfinding que usam RV. Com este intuito, foram desenvolvidas duas interfaces de navegação para Realidade Virtual (i.e., Balance Board e Walk-in-Place), também numa perspectiva de DCU, para garantir um constante ciclo de testes e aperfeiçoamento das implementações junto dos utilizadores. Foi realizado um estudo comparativo entre estas duas interfaces de navegação e uma outra que é utilizada mais frequentemente em estudos com RV (i.e., um Joystick). Este estudo comparativo realizou-se num contexto de avaliação da consonância comportamental com avisos de segurança e foram analisadas variáveis de desempenho, assim como os níveis de presença das diferentes interfaces de navegação. Não se observaram diferenças estatisticamente significativas em relação aos níveis de presença nem em relação à consonância comportamental entre as três interfaces de navegação. No entanto, foram encontradas diferenças estatisticamente significativas em várias variáveis de desempenho (e.g., velocidade média, distância percorrida). Também são discutidas as possíveis linhas de investigação de continuação ao trabalho

A New Relational Spatial OLAP Approach For Multi-resolution and Spatio-multidimensional Analysis of Incomplete Field Data

International audienceIntegrating continuous spatial data into SOLAP systems is a new research challenge. Moreover, representation of field data at different scales or resolutions is often mandatory for an effective analysis. Thus, in this paper, we propose a logical model to integrate spatial dimensions representing incomplete field data at different resolutions in a classical SOLAP architecture

THE PROCESS AUGMENTABILITY CANVAS - HOW TO FIND THE SWEET SPOT FOR AUGMENTED REALITY

The adoption of augmented reality (AR) has been one of the defining technological trends of the past decade. While AR has experienced significant growth in consumer electronics, its potential for professional use still needs to be explored. Despite the growing interest in AR, determining its feasibility and potential to satisfy business needs remains challenging. To address this gap, we used a mixedmethod research approach to create a guiding framework called the process augmentability canvas. Drawing on a comprehensive case study of a major European maintenance, repair, and overhaul service provider, as well as state-of-the literature, we present a canvas that allows scholars and practitioners to evaluate AR’s applicability for a given process thoroughly. By providing a structured approach to analyzing AR solutions, the process augmentability canvas contributes to a better understanding of how AR can be used efficiently in organizational settings

Prev Chronic Dis

Preterm birth (<37 weeks gestation) continues to be a significant cause of disease and death in the United States. Its complex causes are associated with several genetic, biological, environmental, and sociodemographic factors. Organizing and visualizing various data that may be related to preterm birth is an essential step for pattern exploration and hypothesis generation and presents an opportunity to increase public and stakeholder involvement. In this article, we describe a collaborative effort to create an online geographic data visualization tool using open software to explore preterm birth in Fresno County, where rates are the highest in California. The tool incorporates information on births, environmental exposures, sociodemographic characteristics, the built environment, and access to care. We describe data sets used to build the tool, the data-hosting platform, and the process used to engage stakeholders in its creation. We highlight an important example of how collaboration can increase the utility of geographic data visualization to improve public health and address health equity in birth outcomes.31400100PMC6716387663

Designing data warehouses for geographic OLAP querying by using MDA

Data aggregation in Geographic Information Systems (GIS) is a desirable feature, spatial data are integrated in OLAP engines for this purpose. However, the development and operation of those systems is still a complex task due to methodologies followed. There are some ad hoc solutions that deal only with isolated aspects and do not provide developer and analyst with an intuitive, integrated and standard framework for designing all relevant parts. To overcome these problems, we have defined a model driven approach to accomplish Geographic Data Warehouse (GDW) development. Then, we have defined a data model required to implement and query spatial data. Its modeling is defined and implemented by using an extension of UML metamodel and it is also formalized by using OCL language. In addition, the proposal has been verified against a example scenario with sample data sets. For this purpose, we have accomplished a developing tool based on Eclipse platform and MDA standard. The great advantage of this solution is that developers can directly include spatial data at conceptual level, while decision makers can also conceptually make geographic queries without being aware of logical details.This work has been partially supported by the ESPIA project (TIN2007-67078) from the Spanish Ministry of Education and Science and by the QUASIMODO project (PAC08-0157-0668) from the Castilla-La Mancha Ministry of Education and Science (Spain).

M+D: conceptual guidelines for compiling a materials library

This article proposes to present a study conducted by the Raw Materials research group, the results of which comprise the conceptual guidelines for compiling an M+D material library. The study includes the topic, materials and design taking the impact of the changes that came into being in the post industrial era on project methodologies and the search for information regarding materials. Taking into account the importance and complexity that these relationships have taken on currently, we have studied the issue of materials based on Manzini (1983) and Ashby and Johnson (2002). Afterward different databases and materials libraries located in the Brazil, the United States, France and Italy geared toward design professionals and students were analyzed to understand what information and means of access to them were available. The project methodologies were approached based on Löbach (1991), Bürdeck (1994), Schulmann (1994), Baxter (1998), Dantas (1998 and 2005) and Papanek (1995 and 2000). This study sought to identify the key elements of the role of materials in the project process today, to serve as a parameter for the analysis of the models studied. A comparative analysis of the models investigated enabled identification of positive and negative aspects to adapt to the needs previously mentioned and identify conceptual guidelines for compiling a collection of materials for use in design projects.

Choreographic and Somatic Approaches for the Development of Expressive Robotic Systems

As robotic systems are moved out of factory work cells into human-facing environments questions of choreography become central to their design, placement, and application. With a human viewer or counterpart present, a system will automatically be interpreted within context, style of movement, and form factor by human beings as animate elements of their environment. The interpretation by this human counterpart is critical to the success of the system's integration: knobs on the system need to make sense to a human counterpart; an artificial agent should have a way of notifying a human counterpart of a change in system state, possibly through motion profiles; and the motion of a human counterpart may have important contextual clues for task completion. Thus, professional choreographers, dance practitioners, and movement analysts are critical to research in robotics. They have design methods for movement that align with human audience perception, can identify simplified features of movement for human-robot interaction goals, and have detailed knowledge of the capacity of human movement. This article provides approaches employed by one research lab, specific impacts on technical and artistic projects within, and principles that may guide future such work. The background section reports on choreography, somatic perspectives, improvisation, the Laban/Bartenieff Movement System, and robotics. From this context methods including embodied exercises, writing prompts, and community building activities have been developed to facilitate interdisciplinary research. The results of this work is presented as an overview of a smattering of projects in areas like high-level motion planning, software development for rapid prototyping of movement, artistic output, and user studies that help understand how people interpret movement. Finally, guiding principles for other groups to adopt are posited.Comment: Under review at MDPI Arts Special Issue "The Machine as Artist (for the 21st Century)" http://www.mdpi.com/journal/arts/special_issues/Machine_Artis
