The Teutonic Bore Camp, comprised of the Teutonic Bore, Jaguar and Bentley deposits, is one of the most significant volcanic-hosted massive sulphide (VHMS) camps in Western Australia. despite being extensively studied, only recently there have been advances in the understanding of the mechanism that drove the formation of mineralisation. It has been recognized by recent studies that the volcanic-hosted deposits from the Teutonic Bore Camp represent replacement-type VHMS systems, with significant input of fluids and metals from a magmatic source. This paper tests the existing hypothesis that the nearby Penzance granite acted as the metals source and/or thermal engine driving the development of these ore deposits. New age constraints on the formation of the host volcanic sequence at the Bentley deposit and the crystallization of the Penzance granite allows for the construction of a 4d evolutionary model for the ore system. A new U-Pb SHRIMP monazite age of 2681.9 +/- 4.5 Ma indicates that the Penzance granite post-dates the host stratigraphy at Bentley (ca. 2693 Ma) and is probably coeval with mineralisation. All zircons (Penzance, Bentley units I and III) have very similar epsilon Hf-(i), with most values between -1 and + 6, slightly higher than the epsilon Hf-(i) of zircons from other granites and volcanics within the Kurnalpi Terrain, and indicative of juvenile sources. The mean Th/U ratios are similar to 0.7 and similar to 0.6 for the Penzance and Bentley zircons, respectively. All zircons have similar Ce/Nd-(CN) ratios. The chemical similarities between the zircons from the granite and the volcanic rocks at Bentley support a shared magmatic source between the Penzance and the Teutonic Bore Camp sequence. The Penzance granite is the likely source of heat, and potentially metals, which drove the VHMS mineralisation at the Teutonic Bore Camp.

Temporal analyses and multi-temporal 3d reconstruction are fundamental for the preservation and maintenance of all forms of Cultural Heritage (CH) and are the basis for decisions related to interventions and promotion. Introducing the fourth dimension of time into three-dimensional geometric modelling of real data allows the creation of a multi-temporal representation of a site. In this way, scholars from various disciplines (surveyors, geologists, archaeologists, architects, philologists, etc.) are provided with a new set of tools and working methods to support the study of the evolution of heritage sites, both to develop hypotheses about the past and to model likely future developments. The capacity to "see" the dynamic evolution of CH assets across different spatial scales (e.g. building, site, city or territory) compressed in diachronic model, affords the possibility to better understand the present status of CH according to its history. However, there are numerous challenges in order to carry out 4d modelling and the requisite multi-data source integration. It is necessary to identify the specifications, needs and requirements of the CH community to understand the required levels of 4d model information. In this way, it is possible to determine the optimum material and technologies to be utilised at different CH scales, as well as the data management and visualization requirements. This manuscript aims to provide a comprehensive approach for CH time-varying representations, analysis and visualization across different working scales and environments: rural landscape, urban landscape and architectural scales. Within this aim, the different available metric data sources are systemized and evaluated in terms of their suitability.

diachronic studies are central to cultural heritage research for the investigation of change, from landscape to architectural scales. Temporal analyses and multi-temporal 3d reconstruction are fundamental for maintaining and safeguarding all forms of cultural heritage. Such studies form the basis for any kind of decision regarding intervention on cultural heritage, helping assess the risks and issues involved. This article introduces a European-wide project, entitled "Cultural Heritage Through Time", and the case study research carried out as a component of the project in the UK. The paper outlines the initial stages of the case study of landscape change at three locations on Hadrian's Wall, namely Beckfoot Roman Fort, Birdoswald Roman Fort and Corbridge Roman Station, all once part of the Roman Empire's north-west frontier. The main aim of the case study is to integrate heterogeneous information derived from a range of sources to help inform understanding of temporal aspects of landscape change. In particular, the study sites are at risk from natural hazards, notably erosion and flooding. The paper focuses on data collection and collation aspects, including an extensive archive search and field survey, as well as the methodology and preliminary data processing.

In recent decades, 3d reconstruction has progressively become a tool to show archaeological and architectural monuments in their current state, presumed past aspect and to predict their future evolution. The 3d representations trough time can be useful in order to study and preserve the memory of Cultural Heritage and to plan maintenance and promotion of the historical sites. This paper represent a case study, at architectonic and urbanistic scale, based on methodological approach for CH time-varying representations proposed by JPI-CH European Project called Cultural Heritage Through Time (CHT2). The work is focused on the area of Milan Roman circus, relatively to which was conducted both a thorough philological research based on several sources and a 3d survey campaign of still accessible remains, aiming at obtaining the monumental representation of the area in 3 different ages.

For more than a decade research has shown that 4d Building Information modelling (BIM) can improve construction planning, scheduling and production control as well as the onsite management of safety, workspaces and waste. The increasing use of 4d BIM in construction highlights opportunities for utilising these capabilities in new digital management systems replete with role reorganization, new practices and workflows, and not solely as a tool for constructability analysis and onsite monitoring of construction progress. Continued focus on construction-based environmental impacts provides an impetus to leverage 4d BIM to improve communication and information flow throughout environmental planning and management tasks. This paper explores how environmental planning and management can be supported by 4d capabilities. 4d modelling and analysis technologies combined with structured workflows are presented as the basis for developing a tailored framework for environmental planning and management. Five functional prerequisites necessary to the collaborative development and onsite monitoring of environmental management systems are identified before laying out the directions for future research.

Surface Motion Capture Animation

Surface Motion Capture Animation

作者： Adnane Boukhayma Universite Grenoble Alpes

学位级别：博士

As a new alternative to standard motion capture, 4d surface capture is motivated by the increasing demand from media production for highly realistic 3d content. Such data provides real full shape, appearance and kinematic information of the dynamic object of interest. We address in this work some of the tasks related to the acquisition and the exploitation of 4d data, as obtained through multi-view videos, with an emphasis on corpus of moving subjects. Some of these problems have already received a great deal of interest from the graphics and vision communities, but a number of challenges remain open in this respect. We address namely example based animation synthesis, appearance modelling, semantic motion transfer and variation synthesis. We first propose a method to generate animations using video-based mesh sequences of elementary movements of a shape. New motions that satisfy high-level user-specified constraints are built by recombining and interpolating the frames in the observed mesh sequences. Our method brings local improvement to the synthesis process through optimized interpolated transitions, and global improvement with an optimal organizing structure that we call the essential graph. We then address the problem of building efficient appearance repre- sentations of shapes observed from multiple viewpoints and in several movements. We propose a per subject representation that identifies the underlying manifold structure of the appearance information relative to a shape. The resulting representation encodes shape appearance variabilities due to viewpoint and illumination, with Eigen textures, and due to local inac- curacies in the geometric model, with Eigen warps. In addition to providing compact representations, such decompositions also allow for appearance interpolation and appearance completion. We additionally address the problem of transferring motion between captured 4d models. Given 4d training sets for two subjects for which a sparse set of semant

Purpose - The section of the research presented in this paper aims to review and explore health and safety (H&S) issues on construction sites. It has the sole intention of using better computer visualisation to meet the needs of site practitioners in understanding such H&S problems. design/methodology/approach - The methodology follows a traditional literature review approach to understand the development of building information modelling (BIM) technology up to its current status. A questionnaire survey was conducted to gather information on the embedding of H&S planning by site practitioners within the BIMenvironment. Findings - BIM has the potential to be used in H&S planning procedures, particularly in those related to tasks on construction sites. A framework for an integrated visual tool is developed for better H&S practice on site. It may be used actively by all practitioners, starting with site induction and addresses, inter alia, personal hazard perception. Research limitations/implications - This paper provides a foundation for developing a tool that helps construction personnel explore potential H&S risks on site before construction begins. By introducing a framework for integrating BIM and project planning, a prototype can be developed to demonstrate the application of the proposed framework. Originality/value - The research presented in this paper introduces BIM usage during the construction stage as a tool that supports a H&S toolbox. The paper proposes the useful framework for better H&S practice on site that can be used actively by all practitioners. The intention is to find a way forward in addressing "real" H&S site issues that may not be easily understood by practitioners without the full aid of visualisation scenarios.

The Iranian construction industry has long been criticized for being inefficient. It has been claimed that 80 percent of all content within the construction process is the same for all projects and there are therefore huge opportunities for improvements. The project manager is essential for the successful delivery of construction projects. The purpose of this paper is to analysis how BIM (Building Information modelling) can be utilized by project managers as a good tool to simulate project condition to avoid redundant works and waste of time and cost. It was concluded that project managers generally have little knowledge concerning BIM, which makes it hard for them to see its applications. The study revealed that BIM can help project managers in the task of delivering successful projects. BIM a better basis for decisions is provided in comparison with traditional projects.

Global Non-rigid Alignment of Surface Sequences

引用

INTERNATIONAL JOURNAL OF COMPUTER VISION 2013年第1-3期102卷 256-270页

作者： Budd, Chris Huang, Peng Klaudiny, Martin Hilton, Adrian Univ Surrey Ctr Vis Speech & Signal Proc Guildford GU2 7XH Surrey England

This paper presents a general approach based on the shape similarity tree for non-sequential alignment across databases of multiple unstructured mesh sequences from non-rigid surface capture. The optimal shape similarity tree for non-rigid alignment is defined as the minimum spanning tree in shape similarity space. Non-sequential alignment based on the shape similarity tree minimises the total non-rigid deformation required to register all frames in a database into a consistent mesh structure with surfaces in correspondence. This allows alignment across multiple sequences of different motions, reduces drift in sequential alignment and is robust to rapid non-rigid motion. Evaluation is performed on three benchmark databases of 3d mesh sequences with a variety of complex human and cloth motion. Comparison with sequential alignment demonstrates reduced errors due to drift and improved robustness to large non-rigid deformation, together with global alignment across multiple sequences which is not possible with previous sequential approaches.
