MODELO SEMÂNTICO DE OPERAÇÕES ARITMÉTICAS E LÓGICAS PARA HARDWARE VIRTUAL

The objective of this project was to develop a semantic model of arithmetic and logical operations for virtual hardware; this goal was achieved through three main steps: Implement logic gates and arithmetic and logic units in Nand2tetris virtual hardware simulator software; Implement recursive and iterative functions to check the correct functioning of logical and arithmetic operations in the p-code machine virtual machine. In the first stage, implementations of the elementary logic gates were developed in the hardware simulator software Nand2tetris. From these logic gates, combinational circuits and sequential circuits were built as logical and arithmetic unit, Half Adder, Full Adder, 16-bit Addition, 16-bit logical negation, 16-bit logical AND, 16-bit logical OR, among others. The second stage involved experimenting at a high level with arithmetic and logical operations, provided by the virtual machine p-code machine, which was implemented in the C programming language, as addition, subtraction, greater than, less than. In the third stage, having already implemented logical and arithmetic operations, iterative and recursive programs were developed to calculate the nth value of the Fibonacci Sequence and the factorial of any number n.

Quantification and Influence of IL-1β on Pain and Inflammatory Response after Placement of a Cement-Screw-Retained Restoration.

Background: The objective of this study was to evaluate the pain and inflammatory response in soft tissues using healing and prosthetic abutments of different diameters and lengths. Methods: The study population was rehabilitated with Astra Tech EV single implants (Dentsply Sirona, Atlantis, Dentsply Sirona S.A., Barcelona, Spain) of 4.2 and 4.8 millimetres in diameter in the upper and lower maxilla and loaded with custom abutments digitally designed using Dentsply Sirona's Virtual Atlantis Design software (Atlantis WebOrder, Dentsply Sirona S.A., Barcelona, Spain), version 4.6.5. The custom abutments had a larger diameter than the healing abutments to evaluate for biomarkers through ELISA. Results: Rehabilitations in the mandible and with healing abutments with diameters less than 4.29 mm and rehabilitators with diameters less than 2.18 mm elicited a higher pain and inflammatory response and, in turn, higher interleukin-1β values. Conclusions: Greater inflammation was evident in cases in which healing abutments with reduced diameter were used compared to the same subsequent rehabilitation with prosthetic abutments with larger diameters.

Effects of added trunk load on the in vivo kinematics of talocrural and subtalar joints during landing

BackgroundLanding from heights is a common movement for active-duty military personnel during training. And the additional load they carry while performing these tasks can affect the kinetics and ankle kinematic of the landing. Traditional motion capture techniques are limited in accurately capturing the in vivo kinematics of the talus. This study aims to investigate the effect of additional trunk load on the kinematics of the talocrural and subtalar joints during landing, using a dual fluoroscopic imaging system (DFIS). MethodsFourteen healthy male participants were recruited. Magnetic resonance imaging was performed on the right ankle of each participant to create three-dimensional (3D) models of the talus, tibia, and calcaneus. High-speed DFIS was used to capture the images of participants performing single-leg landing jumps from a height of 40 cm. A weighted vest was used to apply additional load, with a weight of 16 kg. Fluoroscopic images were acquired with or without additional loading condition. Kinematic data were obtained by importing the DFIS data and the 3D models in virtual environment software for 2D–3D registration. The kinematics and kinetics were compared between with or without additional loading conditions. ResultsDuring added trunk loading condition, the medial-lateral translation range of motion (ROM) at the talocrural joint significantly increased (p < 0.05). The subtalar joint showed more extension at 44–56 ms (p < 0.05) after contact. The subtalar joint was more eversion at 40–48 ms (p < 0.05) after contact under the added trunk load condition. The peak vertical ground reaction force (vGRF) significantly increased (p < 0.05). ConclusionsWith the added trunk load, there is a significant increase in peak vGRF during landing. The medial-lateral translation ROM of the talocrural joint increases. And the kinematics of the subtalar joint are affected. The observed biomechanical changes may be associated with the high incidence of stress fractures in training with added load.

Virtual reality as a tool to enhance the efficiency and reliability of the virtual reconstruction process for heritage/archaeological sites: The case of umm Al-Jimal in Jordan

The growing attention towards reconstruction, driven by its potential to promote sustainable heritage preservation, is impacted by a shortage of the data, sources, and interpretive methods employed in virtual reconstruction. Consequently, the public (individuals and reviewers/Professionals) faces challenges in determining between the original elements and the added elements, in addition to identifying the origin of the new elements. Despite researchers' efforts to implement virtual reality as a solution, its effectiveness is constrained to the end outcome due to the lack of integration of reconstruction information. A set of factors contribute to the challenge of incorporating interactive information into virtual reality, including the researcher's expertise in virtual reality software and the deterministic nature of the C programming language. This necessitates the development of more user-friendly methods to support researchers in reducing the shortage and limitations. As a result, the study aims to develop a method for simplifying the process of transferring virtual reconstruction operations to virtual reality and test its efficiency through interviews with individuals and reviewers/Professionals. This is accomplished through the integration of virtual reconstruction steps with the Unreal Engine program, which serves as a virtual reality platform and is easier to program than Unity which is more prevalent in heritage research. The findings delivered a more efficient approach to collecting diverse sources and integrating them into one platform simply. This approach also facilitates direct communication between reviewers/Professionals and researchers, thereby enhancing the efficiency of the reconstruction peer review process. Furthermore, the utilization of virtual reality has played an important role in enhancing comprehension between what is the origin and added, as well as facilitating the validation of the rebuilding procedure among individuals and reviewers/Professionals.

A combination crown lengthening and implant placement guide

Surgical procedures, including crown lengthening and implant placement, have become more predictable and less invasive because of the use of digital planning tools. A method combining a cone beam computed tomography and a digital scan with a virtual planning software program is described to fabricate a combination guide for both surgical esthetic crown lengthening and guided implant placement.

Pre-operative virtual three-dimensional planning for proximal humerus fractures: A proof-of-concept study.

To (1) evaluate surgeon agreement on plating features (position and screw length) in virtual 3D planning software, (2) describe outcomes (fracture reduction, plate position, malpositioning of calcar screws and screw lengths) of plate fixations planned with routine pre-operative assessment (2D- and 3D CT imaging) and those planned with dedicated virtual 3D software of the same proximal humerus fracture. Fourteen proximal humerus fractures were retrospectively reduced and fixed with virtual planning software by eight attending orthopaedic surgeons and compared to the true surgical fixation with post-operative computed tomography (CT) scans. Reduction differences were quantified using CT micromotion analysis. Intraclass correlation for screw lengths was 0.97 (95% CI: 0.96-0.98) and 0.90 (95% CI: 0.79-0.96) for plate position. Mean difference in total fracture rotation of the head between the virtual and conventional group was 22.0°. Plate position in the virtual planning group was 3.2 mm more proximal. There were no differences in inferomedial quadrant calcar screw positioning and, apart from the superior posterior converging screw, no significant differences in screw lengths. Reproducibility on plate position and screw length with virtual planning software is adequate. Apart from fracture reduction, virtual planning yielded similar plate positions, screw malpositioning rates and lengths compared to routine pre-operative assessment.

Evaluating Design Guidelines for Intuitive, Therefore Sustainable, Virtual Reality Authoring Tools

Virtual reality software might be challenging to utilize for beginners and unskilled professionals who do not have a programming or 3D modeling background. Concurrently, there is a knowledge gap in software project design for intuitive virtual reality authoring tools, which were supposed to be easier to use. These tools are frequently insufficient due to a lack of support and standard operating procedures. This study evaluates the validity of fourteen design guidelines for the development of intuitive virtual reality authoring tools. Adopting the Design Science Research approach, a previous study completed the first steps of the protocol by identifying problems, defining solution objectives, and developing and demonstrating the design guidelines. This work evaluates their application in a experiment. A group of engineering students with no prior experience in creating virtual worlds were tasked with examining the design guidelines while using the NVIDIA Omniverse Enterprise as an exemplary use case by following the tutorials in the platform. Previously, the students answered a Likert-scale questionnaire and a focus group interview, with eighteen questions about how they perceived these guidelines. An average score value for the tool was estimated through the questionnaire answers and a correlation analysis and, using the Pearson Correlation Coefficient (PCC), it was confirmed that most guidelines scores behaved as expected and were ranked according to the use-case functionality. The participants understood the guidelines’ definition and could decide if they agreed or disagreed with their presence during the experiment. We evaluated that, in accordance with the Design Science Research, the proposed artifact is useful, i.e., the design guidelines for virtual reality authoring tools perform what they are designed to do and are operationally reliable in accomplishing their goals.

A Comparative Analysis of Physical Therapy Anatomical Knowledge and Retention: Human Donor Dissection Versus Virtual Laboratory.

Despite a long history of using human donor dissection (HDD) for physical therapy (PT) anatomy education, there are no PT guidelines that require HDD. The purpose of this quantitative causal-comparative study was to determine if Doctor of Physical Therapy students who used HDD had different grades both within anatomy and within courses that require retention and application of anatomical knowledge (kinesiology and a foundational musculoskeletal course) compared with those who used virtual 3-dimensional anatomical software (VAS). Numerous factors affect the decision to use HDD within PT anatomy, and few PT studies have compared the effectiveness of VAS to HDD. All students who took anatomy in an entry-level PT program from 2018 to 2021 (232 total students, 115 who used HDD in 2018-2019 and 117 who used VAS in 2020-2021). Mann-Whitney tests were used to compare anatomy grades (course, written examination, and practical examination) and future grades in kinesiology and a foundational musculoskeletal course for students who used HDD or VAS. Physical therapy students who used VAS had statistically significant higher anatomy course grades (VAS 93.81% ± 4.99% to HDD 92.20% ± 4.53%) and higher practical examination grades (VAS 97.43% ± 2.91% to HDD 93.55% ± 4.39%) compared with those who used HDD. However, there were no significant differences between groups on written anatomy examinations (VAS 89.42% ± 7.21% to HDD 90.40% ± 4.94%), kinesiology grades (VAS 91.86% ± 4.52% to HDD 92.80% ± 4.27%), or foundational musculoskeletal grades (VAS 89.50% ± 3.89% to HDD 89.77% ± 3.83%). The causal-comparative study design prevents concluding that PT student grade differences were due exclusively to either anatomy laboratory method. It does provide preliminary evidence that the PT anatomy laboratory method did not practically affect anatomy performance or long-term application of anatomy knowledge in future coursework.

A hybrid solar–biogas system for post-COVID-19 rural energy access

Abstract Solar home systems for rural electrification are often designed with a limited energy supply, which presents a drawback for the technology. Furthermore, uncontrolled livestock faeces in rural communities constitute environmental sanitation and health risks. Livestock excrement can be used through a biogas digester to supplement solar energy to provide adequate and sustainable electricity access to underserved rural communities while achieving waste management. Therefore, this study presents a hybrid solar–biogas system for a more dynamic energy supply and waste management for post-Covid recovery plans in rural communities. A parametric research approach that involves the use of the Integrated Environment Solution Virtual Environment software application and mathematical models to design the desired household load and the hybrid system sizing is used in the study. The findings show that the daily household energy consumption was 6.6 kWh, equivalent to 206.40 kWh/month. A 1.2-kWp and 1.2-m3 hybrid solar–biogas system was found to adequately power the house. Financially, the total initial investment cost of the system was $5777.20 with a net present value of $6566.78, net profit of $4443.6, a payback period of 14 years and 8 months, and a levelized cost of energy of $0.21/kWh; these include a 60% initial investment and maintenance costs subsidy. Energy performance contracting and energy-as-a-service were recommended to effectively run and operate the system. The study successfully revealed the design, specifications and upscaling mechanism of the proposed hybrid solar–biogas system. More research is required to unveil the efficacy of the system, the performance gap and the perception of the technology by the beneficiaries.

Students training on virtual medical linear accelerator

At the Czech Technical University in Prague, we have installed virtual software environment simulating a radiotherapy treatment room with a medical linear accelerator (software VERT and VERT Physics by Vertual Ltd., United Kingdom). It is possible to simulate patient treatment and physics QA (quality assurance) measurements in virtual reality. This is beneficial for our students and teachers because there is no radiation present while doing the exercises and it is accessible at any time, unlike medical linear accelerators at hospitals. For our department, we have chosen the TrueBeam model by Varian Medical Systems, USA. The linear accelerator can be operated by the user in the same way as at the hospital, including the hardware pendant. There is a selection of patient treatment plans, CT images and RT structures, all of which can be visualised inside the treatment room, also during beam on, simulating the situation inside the patient while irradiating the tumour. Any DICOM files, even from another manufacturer’s linac (linear accelerator) or treatment planning system, can be imported into VERT. Apart from this, there is also an imaging interface and cone-beam CT interface showing options for patient setup. Another part of the software is a physics module with various phantoms and detectors for dosimetry as well as geometry tests. For example, a large water tank can be used for relative dosimetry of photon beams (percent depth doses and profiles), a smaller water phantom can be used for reference dosimetry or chamber cross calibration according to the TRS 398 (1) or IPEM (2) protocol. The results of measurements are based on look-up tables coming from real beam data, so dependence on the depth of measurement, field size, temperature and pressure and other parameters can be demonstrated. Moreover, it is possible to introduce many types of errors into the linac, such as jaw position, laser, or collimator miscalibration, and show how these errors propagate to patient irradiation and how they can be detected by QA tools. This paper is a short report on how this system has been used at our university and how it might be used in modern learning, pointing out its advantages and drawbacks. At the 16th Workshop on European Collaboration in Higher Education on Radiological and Nuclear Engineering and Radiation Protection (CHERNE) it was proposed that this virtual system could be used for an international student training course on medical physics in radiotherapy within the CHERNE network. This course might contain theoretical lectures with demonstrations on the virtual linac, practical exercises on the virtual linac and visits to hospitals (a photon radiotherapy centre, the Thomayer University Hospital in particular, and a proton therapy centre).

Enhanced Soccer Training Simulation Using Progressive Wasserstein GAN and Termite Life Cycle Optimization in Virtual Reality

Virtual Reality (VR) offers the possibility of creating engaging and intensive training programs to enhance sports performance. Football, a widely popular sport worldwide, attracts millions of spectators. However, the physical demands and risks inherent in the game necessitate the creation of a training environment immune to external influences, minimizing sports-related injuries while enhancing player immersion. Existing training methods are affected by external factors like, weather, injuries, and space limitations, hindering effectiveness and skill development. To overcome these issues, in this research, enhanced soccer training simulation using Progressive Wasserstein GAN and Termite Life Cycle Optimization in Virtual Reality (PWGAN-TLCOA-ST-VRT) are proposed. This study begins by analyzing the fundamental features of computer-generated soccer training techniques and introduces the implementation of VRT in football training via PWGAN technology. The goal is to develop virtual systems resilient to external factors and provide theoretical support for the expansion of virtual football sports software. By overcoming constraints like, weather, player injuries, space limitations, and financial constraints, the proposed approach aims to enhance training effectiveness, teaching techniques, and football skill development. Software tools like Poser 8.0, 3Ds MAX and EON Studio are introduced for system development. Evaluation of the proposed PWGAN-TLCOA-ST-VRT method is examined using performance metrics including, precision, accuracy, F1-score, recall, specificity, error rate, computation time, and Receiver Operating Characteristic (ROC) analysis. The proposed PWGAN-TLCOA-ST-VRT technique achieves significant improvements compared to existing approaches like, Analysis of the application of virtual reality technology in football training (AI-ST-VRT), Cortex VR: Immersive analysis and training of cognitive executive functions of soccer players using VR and machine learning, Predict the value of football players using FIFA video game data and machine learning techniques (MLR-ST-VRT)

The Bridge To Acceptance: Investigating Consumer Perceptions of Virtual Bankers

Electronic banking technology advancements have resulted in new methods to process banking transactions, particularly through online banking channels. Virtual bankers are still in their early stages in Nigeria and are not being used as a significant cost-cutting tool for banks or to improve customer relationships. Using the technology acceptance model (TAM), this study will investigate the adoption of virtual bankers by customers of selected banks in Anambra State. The model was tested with a survey sample of 323 people, employing the survey research method as the research design, and simple linear regression to analyze the data. The study findings show that perceived usefulness and perceived ease of use have a positive and significant impact on virtual banker adoption. The study suggests that financial institutions adopt and deploy virtual banker platforms to enable seamless transactions and quick responses to task completion, as well as to improve job performance and overall output within the organization. Additionally, the study recommends that, for effective deployment and adoption of a virtual banker, financial institutions provide learning platforms that will ease the process and ensure that actual and prospective customers become proficient with the use and working processes of the virtual banker. The provision of learning platforms will encourage more consumers to get on board and adopt virtual bankers. Finally, the study suggests that virtual banker platforms and software should be continuously improved. This improvement aims to make them easier to use, faster in responding to consumer needs, and more innovative in addressing the anticipated and ever-growing needs of existing and future customers.

Research into the world of Cloud-Virtual Reality

Virtual Reality technology has not been able to penetrate the mainstream consumer market due to restrictions on hardware and content. With the advancement of cloud computing technologies, Virtual Reality hardware and technology applications may now be supported strongly. The metaverse, cloud VR gaming, and cloud VR stimulator are just a few of the real-world applications that are now employing cloud computing in Virtual Reality. We can lower the cost of Virtual Reality technology which would begin a new era of many users to apply cloud-based technologies. With the aid of technology, it will be possible to operate from anywhere without having to transport a lot of equipment. The performance, usability, and compatibility of Virtual Reality software and hardware can be improved by cloud computing on the level of hardware and content. The VR dataset is made available for public collaboration through the Internet using a VR-Cloud server. The digital asset that represents the layout of our pedestrian bridge comprises images of all the streets, buildings, trees, and other urban amenities. In the virtual environment of the metropolitan area, where they run and stroll according to predetermined behaviour scenarios, the cars and people are created and entered. By employing cloud communication software to analyse simulations of vehicles and pedestrian crowds and to debate design ideas, users share the VR reality by connecting to the VR Cloud servers from remote devices. This research demonstrates how VR-cloud may be combined with Neuralink and NFT in the virtual world for future enhancement. This paper is a research note on cloud computing and its application using the Virtual Reality (VR) platform for the modern world with futuristic innovations. Keywords: Cloud Computing, Metaverse, Neuralink, Virtual Reality, VR-Cloud.)

Orthopaedic Surgery in the Metaverse: Current Data on Virtual-Reality Based Training

BACKGROUND: Immersive, realistic, and low-risk training has long been ideal for skill-based disciplines such as surgery. Recent advances in virtual reality technology have led to development of surgical training software with the goal to provide experience without risk. The aim of this review is to summarize the current data for virtual reality-based orthopaedic surgery training to evaluate how beneficial the technology may become in educational circumstances. METHODS: A literature review was completed analyzing eight randomized controlled trials completed between 2019 to 2022 to evaluate the effect of virtual reality on orthopaedic surgery education for medical students and residents. Each trial included groups of learners that were trained on a specific procedure with standard methods (“control”) or virtual reality software (“VR group”). Subjects were then evaluated on completion of procedures with real-life models. Procedures included total hip arthroplasty (n=2), tibial intramedullary nail (n=2), slipped capital femoral epiphysis pinning (n=2), and unicompartmental knee arthroplasty (n=2). The primary metrics assessed were time to complete procedure and objective assessment scores. Secondarily survey results were evaluated regarding subjects’ perceived utility of virtual reality in orthopaedic surgery training. RESULTS: 168 subjects (medical students n=68, residents n=100) were included across the 8 different trials. All trials included at least one objective assessment and it was found that overall, the VR group performed 19.9% better than control group on average (19.875 ± 18.324, 95% CI). Seven of the trials reported time to complete procedure, in which it was found that overall VR group completed the procedures 12% faster than control group on average (12 ± 10.988, 95% CI). Subjective measures showed that over 70% of subjects found the VR learning to be at least “helpful” or “useful”. CONCLUSION: Early studies of the emerging field of virtual reality in surgical training are promising. When looking at objective measures and time to complete procedures, VR trained learners perform as well, if not better, than standard method learners. Inclusion of virtual reality-based practice in medical school curricula and residency training may lead to less surgical errors, increased knowledge of procedures, and more efficient learning in real-life scenarios. This potential impact extends beyond well-resourced institutions, as VR technology can provide a cost-effective and accessible alternative for surgical training in low-income and low-resource areas of the world, democratizing access to high-quality medical education. Continued research on translation into clinical practice is warranted, with the potential to bridge educational disparities and improve surgical outcomes on a global scale.

Job relevance or perceived usefulness? What features of immersive virtual reality software predict intention to use in a future project-based-learning scenario: a mixed method approach

Not only since COVID-19, the topic of decentralized working and learning methods is becoming increasingly important for various reasons. New virtual reality technologies enable learning in immersive scenarios, which is good when learning from home is advised. However, not all immersive Virtual Reality (iVR) training incorporates learning systems that support complex, realistic, practical tasks that lead to a product or enable acquiring knowledge and life-enhancing skills like project-based learning. Although there are many iVR applications available that support project management, the specific features of these applications that lead to the intention to use (and therefore life-enhancing skills) have yet to be discovered. In this exploratory mixed-method study, we investigated the question of the importance of perceived usefulness (PU) and job relevance (JR) as predictors of intention to use (ItU) in a selection of immersive iVR application features. We started with market research and aggregated 88 software features in 13 categories of 34 professional iVR applications. After an expert selection and ranking procedure, a survey was developed. After deriving from the TAM 2 model and with a sample n = 103, we computed the relationship of JR, PU, and ItU. Although high values were generally observed, we found that the importance of PU is higher than JR when it comes to ItU. Limitations of the study are discussed, and suggestions for further research are given.

Research on Distributed Virtual Reality Technology Based on VIRTOOLS in the Context of Big Data

Abstract In this paper, virtual reality development software Virtools is used as the main tool for scene rendering in distributed virtual reality systems. The nearest distance-based control strategy is designed to achieve synchronous interaction between nodes by utilizing consistency control and prediction algorithms for nodes in the same cluster. Optimize the virtual scene by using texture mapping, detail level, and dynamic loading techniques. Propose a distributed parallel drawing method based on image plane segmentation to accelerate image drawing. The analysis and testing of the multiuser virtual reality roaming system in this paper is completed from four aspects: offline training model evaluation amount roaming test, lock performance test, and operation sequence error correction test. Among the analyzed data, the average lock time overhead is 123us, which has no obvious connection with the number of nodes, the number of locking times, and the execution of operations. According to each lock overhead of 123us, the number of concurrencies allowed per second is 8563, which fully meets the requirements of the system at this stage.
