Abstract:

In this article, I counter persistent claims of big data revolutionising managerial decision making, by tracing the technological and cultural origins of data-based management in the United States back to the 1970s and 1980s using historical source materials from the trade magazine Datamation. I argue that innovations in database technology within this period – database management systems and the relational database model – shaped and reinforced a data-based mindset. This mindset, I demonstrate, is manifested in four interlinked concepts of data: data as asset, data as raw, data as reality, and data as relatable. These concepts, I argue, provide a basis for current associations of big data with ideological values of objectivity and truthfulness. The article contributes to a growing body of work in media and communication studies that deconstructs the ideological discourses facilitating big data’s unquestioned integration in the business world.

Abstract:

Data visualization is viewed as a significant element in data analysis and communication. As the data engagement becomes more and more complex, visual presentation of data does help users understand the data. So far, two-dimensional (2D) data visuals are often used for the data visualization process, but the lack of depth dimension leads to inefficient and limited understanding of the data. Therefore, the effectiveness of augmented reality (AR) in data visualization was studied through the development of an AR Data Visualization application using E-commerce data. Machine learning models are also involved in the development of this AR application for the provision of data using predictive analysis functions. To provide quality E-commerce data and an optimal machine learning model, the data science process is carried out using the python programming language. The E-commerce data selected for this study is open data taken through the Kaggle Website. This database has 9994 data numbers and 21 attributes. This AR data visualization application will make it easier for users to understand the E-commerce data in-depth through the use of AR technology and be able to visualize the forecasts for sales profit based on the algorithm model "Auto-Regressive Integrated Moving Average" (ARIMA).

Abstract:

Object-relational technology provides a significant increase in scalability and flexibility over the traditional relational databases. The additional object-relational features are particularly satisfying for advanced database applications that relational database systems have experienced difficulties. The key factor to the success of object-relational database systems is their performance. This paper aims to review the promises of Object-Relational database systems, examine the reality, and how their promises may be fulfilled through unification with the relational technology. To investigate the performance implications of using object-relational relative to relational technology, the query-oriented BUCKY benchmark has been previously applied to an early object-relational database system, i.e., Illustra 97. This paper presents the results obtained from implementing and running the BUCKY benchmark on Oracle 10g. The results acquired from the work described in this paper are compared with the results obtained in BUCKY benchmark. This study throws light on the functionality of object-relational databases, where object-relational technology has made improvements but some limitations are identified as well. In general, the performance of relational supersedes that of object-relational database system.

Abstract:

Abstract. Asset Tracking is an essential component of building management process. It involves creating and maintaining a database of detailed information of assets such as location, condition, brand, and type. This information can help building owners make informed decisions for cost-effective maintenance of building assets. Existing approaches to perform asset tracking require a manual process of measuring and recording the asset condition and location, which is labour-intensive and costly. The typical approach usually includes a human operator with pen and paper inspecting the site and manually recording the information about the asset. In this paper, we propose an augmented reality asset tracking system using HoloLens to reduce the manual labour involved in this process. The system can automatically detect the asset, record and update its related information by visual inspection. Assets are detected by feeding images captured by the HoloLens built-in camera to a pre-trained object detection network. Using a combination of various sensor readings from the HoloLens, the system can estimate the location of the asset using visual simultaneous localization and mapping (vSLAM). This information is then viewed and verified by the user using the augmented reality user interface. Upon the user confirmation, this information will be uploaded to a database. As a case study, we demonstrate a vending machine tracking system which is able to detect and localise the vending machines in an indoor environment and create a database of vending machine information. The system can detect vending machines with a mean average precision of 94.8% and a localization accuracy of 2.3 meters without pre-screening or user input.

Abstract:

Although the statistics and land inventory from 2014 up to now have made much progress, the Natural Resources and Environment sector, as well as many production units, have put in application some software and supporting tools such as TK2015, gCadas, VietMap XM, TKDesktop 2019, etc. However, these software are mainly manual or semi-automatic, not organized to comply with database standards, while the control of the additional investigation, data editing, must be manipulated, updated many times, so the application of the above software in reality still faces many difficulties and expensive. In order to effectively and synchronously perform land statistics and inventory, additional studies and proposals for scientific and technological improvement are necessary. This article presents a new approach for the purpose of thorough automation in land statistics and inventory based on proposing effective implementation solutions and building statistical databases and land inventory according to current regulations.

Shapovalov V.V., Atamas A.I., Bilyk Zh.I., Shapovalov YE.V. and Uchytel A.D. Structuring Augmented Reality Information on the stemua.science. It is demonstrated that one of the conditions for successful scientific and pedagogical work is exchanging of methodical materials, including with using of augmented reality. We propose to classify approaches of placing methodical materials on closed, open and open-moderated types. One of the important benefits of a closed type is the high quality of the methodical material, but it’s limited by amount of material and the lack of exchange opportunities that are problems, and there are no open-moderated resources in the Ukrainian language. The aim of this article is to analyze approaches of systematization of methodical material with using of augmented reality and recommend using of STEMUA for systematization of them. It is shown that STEMUA allows teachers to develop methodical material and place it on this platform. The platform automatically organizes methodical material in the database. Consequently, the platform is satisfying the methodical needs of Ukrainian teachers for material with using of complementary reality in the teaching. It is recommended for teachers and methodists to provide development and methodical materials with using of augmented reality and add them to the platform database.

Abstract:

BIVRS, Body Image Virtual Reality Scale, is a prototype of a diagnostic freeware tool designed to assess cognitive and affective components of body image. It consists of a non- immersive 3D graphical interface through which the patient is able to choose between 7 figures which vary in size from underweight to overweight. The software was developed in two architectures, the first (A) running on a single user desktop computer equipped with a standard virtual reality development software, and the second (B) split into a server (B1) accessible via Internet and actually running the same virtual ambient as in (A), and a VRML client (B2) so that anyone can access the application. The importance of a virtual reality based body image scale relies on the possibility to rapidly test one's perceived body image in better and different ways. It also provides an opportunity to easily develop a trans-cultural database on body image data. Furthermore, the possibility of using 3D can improve the effectiveness of the test because it is easier for the subject to perceive the differences between the various proposed silhouettes.

Abstract:

Background: The application of virtual and augmented reality technologies to orthopaedic surgery training and practice aims to increase the safety and accuracy of procedures and reducing complications and costs. The purpose of this systematic review is to summarise the present literature on this topic while providing a detailed analysis of current flaws and benefits. Methods: A comprehensive search on the PubMed, Cochrane, CINAHL, and Embase database was conducted from inception to February 2021. The Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines were used to improve the reporting of the review. The Cochrane Risk of Bias Tool and the Methodological Index for Non-Randomized Studies (MINORS) was used to assess the quality and potential bias of the included randomized and non-randomized control trials, respectively. Results: Virtual reality has been proven revolutionary for both resident training and preoperative planning. Thanks to augmented reality, orthopaedic surgeons could carry out procedures faster and more accurately, improving overall safety. Artificial intelligence (AI) is a promising technology with limitless potential, but, nowadays, its use in orthopaedic surgery is limited to preoperative diagnosis. Conclusions: Extended reality technologies have the potential to reform orthopaedic training and practice, providing an opportunity for unidirectional growth towards a patient-centred approach.

Abstract:

We have used the Automated Plate Scanner (APS) at the University of Minnesota to digitize glass copies of the blue and red plates of the original Palomar Observatory Sky Survey (POSS I) with |b| > 20°. The APS Image Database is a database of all digitized images larger than the photographic noise threshold. It includes all of the matched images in the object catalog, as well as those unmatched images above the noise threshold. The matched image data of the catalog has the advantage of confirming the reality of the image. This is especially important for small images near the plate limit. But these are not all of the detected real images; very blue or very red faint objects may be excluded by this matching requirement. The image database allows information on them to be retrieved, and is therefore a valuable complement to the object catalog. The operation of the APS and the scanning procedures are described in detail in Pennington et al. (1993). We are now processing plate data into the image database. A set of query forms, a tutorial and documentation can be found at http://isis.spa.umn.edu/IDB/homepage.idb.html.

Abstract:

The article summarizes the results of a two-year study of the issues related to the virtual reality and augmented reality technologies use to virtually reconstruct Moscow Bely Gorod in the 16th-18th centuries. The authors describe mathematical methods, software and hardware which grant access to the historical reconstruction of historical urban landscapes. An important feature of the reconstruction is the source verification module which was used to construct three-dimensional models of the landscape, buildings and the general scenery. The article names the basic principles which the verification module and its interface are based on and considers some optimum problems solved when constructing the interface. The project uses a hybrid motion tracking system as a combination of optical and inertial data. The archival sources used in the reconstruction process are presented in the virtual environment by means of a 3D graphical user interface for the virtual reality. The information displayed is generated from the database of historical sources which includes information about the urban development and individual buildings of Bely Gorod, their parts, location, purpose, owners and construction date. The database contains both text and graphic historical sources. The results obtained also include new algorithms, software and hardware systems as well as the experiment results.

Objective: To evaluate the evidence for the use of virtual reality to treat balance and gait impairments in multiple sclerosis rehabilitation. Design: Systematic review and meta-analysis of randomized controlled trials and quasi-randomized clinical trials. Methods: An electronic search was conducted using the following databases: MEDLINE (PubMed), Physiotherapy Evidence Database (PEDro), Cochrane Database of Systematic Reviews (CDSR) and (CINHAL). A quality assessment was performed using the PEDro scale. The data were pooled and a meta-analysis was completed. This systematic review was conducted in accordance with the (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) PRISMA guideline statement. It was registered in the PROSPERO database (CRD42016049360). Results: A total of 11 studies were included. The data were pooled, allowing meta-analysis of seven outcomes of interest. A total of 466 participants clinically diagnosed with multiple sclerosis were analysed. Results showed that virtual reality balance training is more effective than no intervention for postural control improvement (standard mean difference (SMD) = −0.64; 95% confidence interval (CI) = −1.05, −0.24; P = 0.002). However, significant overall effect was not showed when compared with conventional training (SMD = −0.04; 95% CI = −0.70, 0.62; P = 0.90). Inconclusive results were also observed for gait rehabilitation. Conclusion: Virtual reality training could be considered at least as effective as conventional training and more effective than no intervention to treat balance and gait impairments in multiple sclerosis rehabilitation.

Abstract:

Abstract The use of image processing for the detection and classification of defects has been a reality for some time in science and industry. New methods are continually being presented to improve every aspect of this process. However, these new approaches are applied to a small, private collection of images, which makes a real comparative study of these methods very difficult. The objective of this paper was to compile a public annotated benchmark, that is, an extensive set of images with and without defects, and make these public, to enable the direct comparison of detection and classification methods. Moreover, different methods are reviewed and one of these is applied to the set of images; the results of which are also presented in this paper.

Abstract:

The paper presents the structure of a multilingual dictionary of keywords, which is an integral part of the bibliographic database of Slavic linguistics iSybislaw representing the digital information retrieval system (www.isybislaw.ispan.waw.pl). The lexical units (keywords) of the language of keywords used in the system are represented primarily by linguistic terms. In spite of a different denotation – the keywords directly denote sets of documents, and indirectly the non-documentary reality, while the terms denote elements of linguistic reality – they are formally equal with linguistic terms, which allows them to map the semantic field of a particular discipline, in this case Slavic linguistics. The dictionary is therefore a domain-based online specialist dictionary, which is a tool for users of the bibliographic database of Slavic linguistics. The dictionary is addressed to all those who deal with linguistics and linguistic terminology, first of all to scholar-linguists, Ph.D. students and students of philologies, as well as translators of academic papers in the field of linguistics.

Abstract:

To assess the effects of virtual reality on patients with musculoskeletal disorders by means of a scoping review of randomized controlled trials (RCTs). The databases included PubMed, IEEE, and the MEDLINE database. Articles involving RCTs with higher than five points on the Physiotherapy Evidence Database (PEDro) scale were reviewed for suitability and inclusion. The methodological quality of the included RCT was evaluated using the PEDro scale. The three reviewers extracted relevant information from the included studies. Fourteen RCT articles were included. When compared with simple usual care or other forms of treatment, there was significant pain relief, increased functional capacity, reduced symptoms of the disorder, and increased joint angles for the virtual reality treatment of chronic musculoskeletal disorders. Furthermore, burn patients with acute pain were able to experience a significant therapeutic effect on pain relief. However, virtual reality treatment of patients with non-chronic pain such as total knee replacement, ankle sprains, as well as those who went through very short virtual reality treatments, did not show a significant difference in parameters, as compared with simple usual care and other forms of treatment. Current evidence supports VR treatment as having a significant effect on pain relief, increased joint mobility, or motor function of patients with chronic musculoskeletal disorders. VR seems quite effective in relieving the pain of patients with acute burns as well.

Abstract:

Virtual Reality (VR) is becoming a mature technology field. To understand its origins and foresee strategies, a study on the last decade of papers published in the Brazilians´ most prominent symposium (the SVR – Symposium on Virtual and Augmented Reality) has been carried out. Papers were classified according to subject of study (including application domains, sub-areas and technologies, among others) as well asresearch structure (including authorship counts and geographical distribution, research approaches, among others). The study shows that health related applications have received most of the attention although techniques and tools proposal have raised the most recently which could be related to the lowlevel programming languages and frameworks preferences found to this community. The number of Augmented Reality (AR) papers has grown steadily and a great variety of underlying knowledge fields (such as 3D interaction and real-time simulation) is a persistent aspect of SVR. Data also show that expected shift from VRML to other 3D Web technologies have already happened. Although oversees participation has been not constant, papers published in English has proven stable in SVR editions. Few institutions from Southeast have dominated the research area but another few from Northeast have just surpassed them. Regarding the research, a lack of higher-level maturity research approaches has been noticed. In addition, it was found difficult to assess the relevance of papers to other researches due to poor abstracts and no centralized database of papers. The analysis of 262 papers suggest that (i) by improving the research budget to the area could impact productivity; (ii) a centralized database would facilitate recovering past contributions and; (iii) that enforcing more scientifically rigorous papers with better abstracts and written in English could raise the visibility of Brazilians´ research in VR/AR.

Abstract:

Aim of the article is to reflect on how digital technologies and ICT are changing the way to analyze, visualize, and communicate architectural heritage. In particular, mixed reality apps favor the constant and ubiquitous combination of reality and virtuality. A new kind of advanced heritage grows, characterized by the mix of tangible heritage and digital heritage: Reality enriches with information and virtuality acquires new potentialities with its matching with reality. This process moves from the development of digital informative models made by 3-D and database complex models, characterized by real time manipulability, navigation and interaction. This context renews people's relationship with images, allowing a sort of “visual turn” in built heritage field, where reality reaffirms its centrality, and the digital sphere opens to new opportunities in architectural heritage's studying, computing, experiencing, and valorization. Follows a claim for transparency of information and computer-based visualization.

Abstract:

Virtual Reality (VR) technology allows the animation of machining operations. The kinematic of the machining operation and the geometry of the parts are allocated prevalently to VR using the Virtual Reality Modeling Language (VRML). In order to visualize the machining operation close to reality, the chip formation process needs to be animated as well. This paper presents the virtual reality animation of external cylindrical turning considering the chip formation and the results of the machining operation, such as the process forces. The chips are described numerically using JavaScript which is embedded into the VRML. The JavaScript accesses in addition to an experimentally generated database in order to display the results of the machining operation. The turning operation is visualized both in a non-immersive graphic user interface and an immersive Cave Automatic Virtual Environment (CAVE).

Full text

Abstract:

The LiverTox database compiles cases of idiosyncratic drug-induced liver injury (iDILI) with the promised aims to help identify hepatotoxicants and provide evidence-based information on iDILI. Weaknesses of this approach include case selection merely based on published case number and not on a strong causality assessment method such as the Roussel Uclaf Causality Assessment Method (RUCAM). The aim of this analysis was to find out whether the promised aims have been achieved by comparison of current iDILI case data with those promised in 2012 in LiverTox. First, the LiverTox criteria of likelihood categories applied to iDILI cases were analyzed regarding robustness. Second, the quality was analyzed in LiverTox cases caused by 46 selected drugs implicated in iDILI. LiverTox included iDILI cases of insufficient quality because most promised details were not fulfilled: (1) Standard liver injury definition; (2) incomplete narratives or inaccurate for alternative causes; and (3) not a single case was assessed for causality with RUCAM, as promised. Instead, causality was arbitrarily judged on the iDILI case number presented in published reports with the same drug. All of these issues characterize the paradox of LiverTox, requiring changes in the method to improve data quality and database reliability. In conclusion, establishing LiverTox is recognized as a valuable effort, but the paradox due to weaknesses between promised data quality and actual data must be settled by substantial improvements, including, for instance, clear definition and identification of iDILI cases after evaluation with RUCAM to establish a robust causality grading.
