Archaeological Artifacts

The field of virtual reality is quickly growing across many disciplines, if none more important than the field of archaeology and cultural heritage.  Numerous artifacts are uncovered each year by archaeological excavations around the world, and only a select few are displayed and recorded in museums while the rest remain hidden away in storage facilities.  The use of virtual reality photography provides a potential solution to this problem. This projects aims to optimize a computational workflow for digitally documenting these artifacts through an in depth analysis of the Diniacopoulos Collection of Greek and Egyptian artifacts in collaboration with the Art Conservation department at Queen’s University.  The Diniacopoulos Collection of artifacts has been held by Queen’s since their donation in 2001 by the estate of Olga Diniacopoulos.  This project combines studio Photogrammetry with a method known as Focus Stacking to optimize the quality of each image.  First, images of each object will be used to generate scaled photogrammetric models in Agisoft Photoscan. The same images used to create the 3D models can also be used to create lower-resolution virtual reality movies that are easily shared on websites using the GardenGnome ObjectVR software.  Utilizing another growing industry, 3D printing, takes this method one step further.  3D printing archaeological finds provides people with a tactile experience with the artifacts that would otherwise be kept safe inside museum cases or warehouses where the public has no access. These methods have applications is not only archaeology, but in a number of collaborative fields.

In the last few years, the construction industry’s primary energydem and in developed economies accounted for 30%–40%, and technological innovation is considered to be an urgent need for the transformation and upgrading of the construction industry. New technological innovations are continually changing the way the construction industry is implemented. In the construction industry, artificial intelligence is beginning to change all aspects of the construction industry, in the field of equipment planning, overall layout, safety, management and other fields have caused many changes. The integration of new technologies has revolutionized the traditional construction industry, such as virtual reality technology and 3D printing technology. In this work, we propose a categorization for assessing Virtual reality and 3D printing of Architectural Innovation on the basis of quality of experience (QoE) metric Evaluation of virtual environment using Fuzzy Logic (FL) System. The simulation result is analysed based on the comparative analysis of user experience with Fuzzy logic estimation for perception of virtual environment. The result analysis validated that the proposed FL system replicates the user valuation for architecture innovation applications more precisely and accurately thus FL is efficient method for predicting the inclusive QoE of a virtual reality and 3D printing. This paper will recapitulate the expansion of the two techniques in the manufacture engineering, demeanor examination on the presentation of diverse skills in architectural innovation, as well as explain through real cases how these two techniques have an influence on the improvement of the manufacture engineering. Simultaneously, this paper discourses the limitations of technology mixing and put advancing opinions on the future development of the manufactureengineering.

This paper reflects ongoing research about how new technology creates new possibilities within crafting and how it can build on traditional techniques within the field of ceramics. The research explores how virtual reality (VR), using Oculus Rift and 3D-printing in clay is suitable to link to the process of throwing vessels within ceramic crafts. The quality of the crafted objects in question is based on the ability of the presented technique to combine throwing and pattern-making as an integrated process while building up the thrown object, here named virtual pattern-throwing. Furthermore, it is argued that this use of VR for throwing makes it possible to recall a hands-on experience and thus weave the quality of the traditional craftsmanship with the virtual within the process of making vessels.

As standard practice in orthopedic surgery, the information gathered by analyzing Computer Tomography (CT) 2D images is used for patient diagnosis and planning surgery. Lately, these virtual slices are the input for generating 3D virtual models using DICOM viewers, facilitating spatial orientation, and diagnosis. Virtual Reality (VR) and 3D printing (3DP) technologies are also reported for use in anatomy visualization, medical training, and diagnosis. However, it has not been yet investigated whether the surgeons consider that the advantages offered by 3DP and VR outweigh their development efforts. Moreover, no comparative evaluation for understanding surgeon’s preference in using these investigation tools has been performed so far. Therefore, in this paper, a pilot usability test was conducted for collecting surgeons’ opinions. 3D models of knee, hip and foot were displayed using DICOM 3D viewer, two VR environments and as 3D-printed replicas. These tools adequacy for diagnosis was comparatively assessed in three cases scenarios, the time for completing the diagnosis tasks was recorded and questionnaires filled in. The time for preparing the models for VR and 3DP, the resources needed and the associated costs were presented in order to provide surgeons with the whole context. Results showed a preference in using desktop DICOM viewer with 3D capabilities along with the information provided by Unity-based VR solution for visualizing the virtual model from various angles challenging to analyze on the computer screen. 3D-printed replicas were considered more useful for physically simulating the surgery than for diagnosis. For the VR and 3DP models, the lack of information on bone quality was considered an important drawback. The following order of using the tools was preferred: DICOM viewer, followed by Unity VR and 3DP.

Quality Of Medical Care

Assuring the quality of medical care is now mandated by law. The method to be used initially of peer review through organizations built to review hospital care paid for by Medicare and Medicaid is one step along a long road to guarantee or to improve the quality of care. It would seem wise to begin with simple and uniform data that can yield some idea of what is going on in the process of delivering care. The use of the uniform hospital discharge abstract is one place to begin. I believe we should not ignore nor condemn this public mandate because it will be so rudimentary at the beginning. It is necessary to have limited expectations of what these new organizations can be expected to accomplish. The negative comments should not reduce the importance of this national experiment. We can begin with an active program of applied research to define the goals of health care better, to develop better methods to measure these goals, to document some of what now happens in practice, and to remember that the purpose of the exercise is not to police health care but to stimulate better care and better health for the public. We are embarking on a major social experiment, one that no nation has even before attempted. With initial limited goals and willing participation of physicians in the program my judgment is that more good than harm will result.

Custom-made implants, orthotics, orthoses, models for surgical planning and education, and much more are now created using 3D printers. In this article, the authors suiiunarized information on laws and regulations in the domain of legal support for 3D printing of medical devices in Russia and abroad. 3D printing is one of the promising avenues in developing new methods of treatment, so iiiunediate establishing of clear criteria for its legal regulation is necessary. As is, there are still many gaps in the legislative framework. The issues of the quality of 3D models, material standardization and manufacturing processes using 3D printing technologies remain unresolved. When using custom-made medical devices, respecting the rights of patients and preventing the use of prohibited or restricted materials are essential. Yet, legal barriers to this irmovative direction of medicine must be avoided.

City Models

3D city models are mainly viewed on computer screens, but many municipalities also use 3D printing to make urban planning tangible. Since 3D color printing is still comparatively expensive and the colors often fade over time, many of these models are monochrome. Here, color textured paper models offer an inexpensive and under-appreciated alternative. In this paper, a greedy algorithm adapted to CityGML building models is presented, which creates print templates for such paper models. These 2D layouts consist of cut edges and fold edges that bound polygons of a building. The polygons can be textured or left blank depending on the existence of CityGML textures. Glue tabs are attached to cut edges. In addition to the haptic 3D visualization, the quality of the 3D models can sometimes be better assessed on the basis of the print templates than from a perspective projection. The unfolding procedure was applied to parts of the freely available CityGML model of Berlin as well as to parts of models of the cities of Dortmund and Krefeld.

Although 3D models are useful to preserve the information about historical artefacts, the potential of these digital contents are not fully accomplished until they are not used to interactively communicate their significance to non-specialists. Starting from this consideration, a new way to provide museum visitors with more information was investigated. The research is aimed at valorising and making more accessible the Egyptian funeral objects exhibited in the Sforza Castle in Milan. The results of the research will be used for the renewal of the current exhibition, at the Archaeological Museum in Milan, by making it more attractive. A 3D virtual interactive scenario regarding the “path of the dead”, an important ritual in ancient Egypt, was realized to augment the experience and the comprehension of the public through interactivity. Four important artefacts were considered for this scope: two ushabty, a wooden sarcophagus and a heart scarab. The scenario was realized by integrating low-cost Virtual Reality technologies, as the Oculus Rift DK2 and the Leap Motion controller, and implementing a specific software by using Unity. The 3D models were implemented by adding responsive points of interest in relation to important symbols or features of the artefact. This allows highlighting single parts of the artefact in order to better identify the hieroglyphs and provide their translation. The paper describes the process for optimizing the 3D models, the implementation of the interactive scenario and the results of some test that have been carried out in the lab.
