The transformation towards a low carbon energy system requires municipalities to improve their local building stock. Urban building energy modelling (UBEM) is an emerging tool to support municipalities in shaping the necessary strategies by estimating energy demand with high spatial and temporal resolution. This study proposes a Functional Mockup Interface (FMI)-based UBEM that enables interactive capacities to simulate diverse environmental conditions without reinitialisation. The FMI-based approach allows to couple the building energy simulation EnergyPlus with external models. These capacities were tested on a real-world example in the German city of Wuppertal with urban microclimate data. The results are estimates of sub-hourly energy demand based on the adjacent environmental conditions of each building. In order to ameliorate the applicability, the FMI-based UBEM is further enriched by incorporating an automatic procedure to derive 3d building models, displaying high geometrical fidelity, from city-wide point clouds through the screened Poisson surface reconstruction algorithm. The study area contains 5736 residential buildings. A diverse residential building stock was modelled on the basis of the EU project TABULA. To demonstrate the functionality of the proposed UBEM, a demand response scenario was constructed with microclimate data and heat pumps instead of other heating and hot water systems. The capacity of UBE-FMI to dynamically change parameters (e.g. thermostat setpoint) in the building models can benefit the evaluation of demand response strategies and its potential to shed peak loads. In comparison with reference studies, UBE-FMI produced reasonable estimates of energy demand. The 3d building models and simulation results using "live" weather are visualized by a web-interface, which is implemented with the geospatial 3d framework NASA WorldWind. (c) 2021 Elsevier Ltd.

We present the design and evaluation of an interface that combines tactile and tangible paradigms for 3d visualization. While studies have demonstrated that both tactile and tangible input can be efficient for a subset of 3d manipulation tasks, we reflect here on the possibility to combine the two complementary input types. Based on a field study and follow-up interviews, we present a conceptual framework of the use of these different interaction modalities for visualization both separately and combined-focusing on free exploration as well as precise control. We present a prototypical application of a subset of these combined mappings for fluid dynamics data visualization using a portable, position-aware device which offers both tactile input and tangible sensing. We evaluate our approach with domain experts and report on their qualitative feedback.

Antibiotics are a mainstay of modern medicine, but as they kill their target pathogen(s), they often affect the commensal microbiota. Antibiotic-induced microbiome dysbiosis is a growing research focus and health concern, often assessed via analysis of fecal samples. However, such analysis does not inform how antibiotics influence the microbiome across the whole host or how such changes subsequently alter host chemistry. In this study, we investigated the acute (1 day postadministration) and delayed (6 days postadministration) effects of a single parenteral dose of two common antibiotics, ampicillin or vancomycin, on the global metabolome and microbiome of mice across 77 different body sites from 25 different organs. The broader-spectrum agent ampicillin had the greatest impact on the microbiota in the lower gastrointestinal tract (cecum and colon), where microbial diversity is highest. In the metabolome, the greatest effects were seen 1 day posttreatment, and changes in metabolite abundances were not confined to the gut. The local abundance of ampicillin and its metabolites correlated with increased metabolome effect size and a loss of alpha diversity versus control mice. Additionally, small peptides were elevated in the lower gastrointestinal tract of mice 1 day after antibiotic treatment. While a single parenteral dose of antibiotic did not drastically alter the microbiome, nevertheless, changes in the metabolome were observed both within and outside the gut. This study provides a framework for how whole-organism-omics approaches can be employed to understand the impact of antibiotics on the entire host. IMPORTANCE We are just beginning to understand the unintended effects of antibiotics on our microbiomes and health. In this study, we aimed to define an approach by which one could obtain a comprehensive picture of (i) how antibiotics spatiotemporally impact commensal microbes throughout the gut and (ii) how these changes influence host chemistry throughout the b

Increased competitive challenges are forcing companies to find better ways to bring their applications to market faster. distributed development environments can help companies improve their time-to-market by enabling parallel activities. Although, such environments still have their limitations in real-time communication and real-time collaboration during the product development process. This paper describes a web-based collaborative framework which has been developed to support the decision making on a 3d design developing process. The paper describes 3d design file for the discussion that contains all relevant annotations on its surface and their visualization on the user interface for design changing. The framework includes a native CAd data converting module, 3d data based real-time communication module, revision control module for 3d data and some sub -modules such as data storage and data management. We also discuss some raised issues in the project and the steps underway to address them. (C) 2015 Society of CAd/CAM Engineers. Production and hosting by Elsevier.

A geoscience perspective on immersive 3d gridded data visualization

We describe visualization software, Visualizer, that was developed specifically for interactive, visual exploration in immersive virtual reality (VR) environments. Visualizer uses carefully optimized algorithms and data structures to support the high frame rates required for immersion and the real-time feedback required for interactivity. As an application developed for VR from the ground up, Visualizer realizes benefits that usually cannot be achieved by software initially developed for the desktop and later ported to VR. However, Visualizer can also be used on desktop systems (unix/linux-based operating systems including Mac OS X) with a similar level of real-time interactivity, bridging the "software gap" between desktop and VR that has been an obstacle for the adoption of VR methods in the Geosciences. While many of the capabilities of Visualizer are already available in other software packages used in a desktop environment, the features that distinguish Visualizer are: (1) Visualizer can be used in any VR environment including the desktop, GeoWall, or CAVE, (2) in non-desktop environments the user interacts with the data set directly using a wand or other input devices instead of working indirectly via dialog boxes or text input, (3) on the desktop, Visualizer provides real-time interaction with very large data sets that cannot easily be viewed or manipulated in other software packages. Three case studies are presented that illustrate the direct scientific benefits realized by analyzing data or simulation results with Visualizer in a VR environment. We also address some of the main obstacles to widespread use of VR environments in scientific research with a user study that shows Visualizer is easy to learn and to use in a VR environment and can be as effective on desktop systems as native desktop applications.

This paper presents a 3dTV application that enables displaying and exploration of thematic information in a 3d environment using the book and carousel metaphor. To achieve its goal the system initially deposits all necessary information to be displayed in an XML data repository. The stored data is then displayed through dynamically created 3d artifacts that build up a 3d carousel with hanging 3d books and flipping 3d pages separated into different sections. The user can interact and explore the displayed information through a toolbar which gives him the ability to activate the carousel, to flip pages and section of pages and to zoom on information.

Tomographic imaging is an important disease diagnosis method. Specific image workstation is usually needed to process and visualize 3d medical image gathered from tomographic imaging equipments, because this process is computation intensive. Specific image workstation is large and expensive, which limits size and price of medical tomographic imaging system. To break these limits, this paper presents an embedded 3d medical image processing and visualization platform based on common dual-core processor. The proposed system parallelizes 3d medical image processing and visualization computing process to meet system real-time requirements. Main contributions of this paper includes analysis of core 3d medical data processing and visualization algorithm. program parallelization method analysis and implementation. system performance measurement and analysis. Program analysis results show that the proposed system fully utilizes hardware resource, and meets low-end and space-efficient medical imaging system requirements.

The Interactive Graphical Ocean database System (IGOdS) is a complete software solution to support studies of ocean, coastal, and inland waters using profiling instrumentation such as a conductivity-temperature-depth (CTd) instrument. If you routinely conduct surveys where you are profiling at a set of geographic locations, collecting CTd profiles, and perhaps also collecting water samples for additional analyses, then the IGOdS program is an ideal way for you to manage your datasets. IGOdS is an easy to use tool that includes functions to optimize the import of data, including both electronically recorded CTd data and discrete sampling results. Final IGOdS data files integrate all data for a survey into a single file, for easy archiving. The program provides a wide variety of data analysis and reporting tools. Numerous entities conduct surveys of water bodies as a requirement in a permit for discharge, to monitor for impacts as well as to characterize background conditions. Coastal discharges of sewage effluent, surface effluent discharges, associated with pulp mills or mining operations, river outflows, enclosed bays, estuaries, harbors, and reservoirs, all can have programs either requiring monitoring, or may have environmental issues that require studies and data gathering to support management efforts.

Volume visualization of temperature in Hamilton Harbour, Lake Ontario

引用

JOURNAL OF GREAT LAKES RESEARCH 1996年第1期22卷 15-25页

作者： Halfon, E [a]Environment Canada Canada Centre for Inland Waters Burlington Ontario L7R 4A6

The inner structures of lakes can be revealed using volume visualization algorithms since lakes are three-dimensional objects that are explored by taking samples at various stations and at different depths. These algorithms did not exist 20 years ago, they could only be run on supercomputers 10 years ago, on workstations 3 years ago, and now they can be run on personal computers. Using computer graphics it is now possible to combine data, their three-dimensional location, and lake topography to create images of water quality patterns which supersede conventional surface, two-dimensional, graphics. Through solid modeling, temperature data collected on 28 May 1990 and 8 August 1990 in Hamilton Harbour, Lake Ontario, are mapped into voxels and projected onto two-dimensional screens. Various three-dimensional representations of temperature data are displayed including water masses with temperatures of less than 12 degrees C, 13 to 14 degrees C, 16 degrees C to 17 degrees C, and greater than 23 degrees C. The calculation of the 3d representations allows the computation of volumetric properties, e.g., masses, since each voxel has water quality values associated with it and these values can be summed or elaborated numerically as needs arise. For example the harbor has a volume of 254 x 10(6) m(3), and the water mass on 28 May 1990 at 12-13 degrees C had a complex three-dimensional shape with a volume of 61 x 10(6) m(3). A third benefit of visualization is that the data can be viewed interactively from different viewpoints thus increasing the interaction between scientist and the data. These methods should also be able to be used in other limnological applications such as visualization of sediments, algal blooms, and other biological and chemical data.
