Abstract For drilling contractors, the moment of truth is the operations at the site. If the technician at the site encounters a problem he can't solve, then everything stops. The team has to wait for a subject matter expert (SME) to arrive at the site to diagnose rectify the problem. Such process of SME mobilization and till that time Non-Productive Time (NPT) results in loss of hundreds of thousands of dollars. Hence the key challenge is converting the Sparse to Adequate availability of Right Knowledge at Right Time at Right Place, for the support of technicians. This paper is focused on the approach of moving from Hand Held devices to Hands-Free environment at sites and connecting local/global support to site support systems, to reduce cost, improve HSE and enhance operational performance. The augmented reality technology-enabled, smart glass laced headsets are rugged, zone 1 certified, and are voice-operated which are better than smart tablets which were considered during Technology Qualification Process. Evaluation criteria were: 1. Availability and follow up of the digital work instruction while operating. Moreover, not missing a single step of work instruction while inspection or maintenance continues was noted carefully. 2. Reduced travel/accommodation cost : Normally at the time of shutdown, the rig crew contacts subject matter experts (SME) and (at times) in turn the SME contacts the OEM support team to mobilize service engineers globally. 3. Response time improvement-Availability of support by SME right at the time of need results from better response time to diagnose and fix the issue at hand. Call logging till final resolution process improvement is considered an important metric. Travel restrictions imposed by Covid-19, are also being addressed through the distanced inspection. A hands-free environment is compared vis a vis handheld device. Better training and knowledge transfer are achieved through better communication methods and this goes better with learning by doing. Subsequent text (NLP-speech to text) analysis is planned through deep learning models to derive related predictions. Sparse to Adequate availability of support to rig staff with Right Knowledge at Right Place at Right Time is the key outcome of this Proof of Value project.

Smartphones and other mobile devices like the iPhone, Android, Kindle Fire, and iPad have boosted educators' interest in using mobile media for education. Applications from games to augmented reality are thriving in research settings, and in some cases schools and universities, but relatively little is known about how such devices may be used for effective learning. This article discusses the selection and potential use of electronic games, simulations and augmented reality in mobile learning supported by an operational model called AIDLET. After analyzing the different approaches to the use of digital technology and games in education, and discussing their benefits and shortcomings, a framework was developed to facilitate the selection, repurposing, design and implementation of games, simulations and augmented reality, with focus on the practical aspects of the processes used in mobile learning. It is apparent that these devices for learning are valued by students and teachers alike, and that they may be used as personalized devices for amplifying learning, specifically through amplifying access to information, social networks, and ability to participate in the world. Furthermore, whereas traditional learning is based on knowledge memorization and the completion of carefully graded assignments, today, games, simulations and virtual environments turn out to be safe platforms for trial and error experimentation, i.e. learning by doing or playing. In this context, the AIDLET model was set out and verified against a taxonomy representing the main categories and genres of games, and the article concludes with implications for how teachers, instructional designers and technologists might best capitalize on the affordances of mobile devices when designing for blended learning and e-learning courses.

The Impact

Abstract Background Polypectomy is an essential endoscopic skill. Training in polypectomy has been identified as a major deficiency for endoscopists worldwide as polypectomy occurs ad hoc during a colonoscopy when a polyp is detected, and a lack of standardized curricula. Augmented reality (AR), which superimposes computer-generated images on a user’s view of the world, can address these gaps by standardizing encounters with polyps while completing simulated procedures and enabling polypectomy-specific teaching. Aims Evaluate the impact of a simulation-based augmented reality curriculum on polypectomy performance among novice endoscopists. Methods This study includes two cohorts of participants from 2019 to 2020. In 2019, participants were randomized into either: (1) a control curriculum, involving 6 hours of simulation-based training (SBT) supplemented by expert feedback, interlaced with 4 hours of small group teaching on the theory of colonoscopy; or (2) the augmented reality curriculum (ARC), in involving the same curriculum with integrated AR, wherein participants engaged with an AR-enhanced video demonstrating relevant therapeutic and pathologic details during polypectomy. The SBT for all participants involved a progressive curriculum starting on a bench-top model and then moving to the EndoVR® virtual reality simulator. The primary outcome was polypectomy-specific performance using the Direct Observation of Polypectomy Skills (DOPyS) tool during a simulated polypectomy after training, with a maximum score of 100. Results Demographic characteristics are summarized in Table. In 2019, 21 novice endoscopists were enrolled. Immediately after training, the mean DOPyS score among ARC group participants was 76.2 (SD=17.9) compared to 71.8 (SD=13.2) among control group participants (Figure). In this interim analysis, there was no significant difference between groups. Data analysis will be completed after 2020 participants complete the study. Conclusions Interim results show a trend towards improved polypectomy performance with no significant difference. The results of this study have the potential to impact polypectomy education among novices. Simulation-based AR interventions may allow learners to progress towards achieving competency in polypectomy in a risk-free environment prior to first patient contact. Funding Agencies None

The Way

Of all the technologies emerging today, augmented reality (AR) stands to be one of, if not the, most transformational in the way we teach our students across the spectrum of age groups and subject matter. The authors propose “best practices” that allow the educator to use AR as a tool that will not only teach the processes of a skill but will also encourage students to use AR as a motivational tool that allows them to discover, explore, and perform work beyond what is capable with this revolutionary device. Finally, the authors provide and explore the artificial intelligence (AI) processors behind the technologies driving down cost while driving up the quality of AR and how this new field of computer science is transforming all facets of society and may end up changing pedagogy more profoundly than anything before it.

Metaheuristic Methods

The work carried out has the purpose of improving and optimizing various industrial technical operations, such as preventive maintenance, taken here as an example of application, using the Design for Disassembly (DfD) technique. Therefore, through four metaheuristic methods that have been chosen among the most widespread in the field (described below) to make a comparison between them, the optimal disassembly sequence is sought, if it exists, in terms of time and then costs in order to extract a target component without damaging the other mechanical parts of the assembly. The hypothesis that has been tested throughout this case study is “a responsible application of DfD, not only from the design process of a product but also during the disassembly procedure, can bring substantial benefits to the company”. Interaction with a hypothetical operator in charge of the work to be performed is implemented with the use of augmented reality. In fact, through an application programmed for an Android device (in this case, a mobile phone, hence a handheld device), the operator can be instructed step-by-step on the disassembly sequence in dynamics as an animation. Finally, two virtual buttons were added in augmented reality with which the operator can start and pause/resume the animation at any time to facilitate the understanding of the different steps established by the sequence.

The article is devoted to topical issues of determining the effectiveness of the work of governmental agencies in the Russian Federation. The relevance of the study’s subject matter is determined by the lack of comprehensive examination of the subject matter from the perspective of methodology and practice. Public authorities’ activities in the Russian Federation are changing acquiring new qualities. Thus, clear and uniform criteria for their assessment are necessary. Evaluation criteria should be closer to social indicators and should meet the demands of society. The author analyzes the normative-legal regulation of this issue. to this end, the paper provides examination of the Decrees of the President of the Russian Federation that have been issued since 2007 to establishing indicators for assessing the effectiveness of the activities of the executive authorities of the Russian Federation. It is possible to observe a constant change in the methodological approach to the number, formulation and content of the criteria for assessing the effectiveness of the executive authorities of the constituent entities of the Russian Federation. Between 2007 and 2012, the evaluation criteria were based on public control over the public services effectiveness exercised by citizens. Currently, the approach has changed — public control has been removed from the system under consideration and is now governed by a separate regulatory act. For the first time, to recognize executive authorities’ activities as effective the determination of the level of evaluation criteria to be met by executive authorities is used.The normative regulation of the evaluation of the effectiveness of the executive power at the federal level is also investigated. At the national level there is no any regulatory framework for assessing the activities of federal executive authorities of the Russian Federation. The author draws conclusions about the lack of a uniform approach to the evaluation of governmental authorities’ activities at both federal and regional levels. The conclusions can be used in law-making activities of state bodies.

BACKGROUND Medical education is evolving from "learning by doing" to simulation-based hands-on tutorials. OBJECTIVE The aim of this prospective 2-armed study was to evaluate a newly developed augmented reality ultrasound app and its effect on educational training and diagnostic accuracy. METHODS We recruited 66 medical students and, using imaging and measuring a kidney as quality indicators, tested them on the time they needed for these tasks. Both groups used textbooks as preparation; in addition, the study group had access to a virtual ultrasound simulation app for mobile devices. RESULTS There was no significant difference between the study arms regarding age (P=.97), sex (P=.14), and previous ultrasound experience (P=.66). The time needed to complete the kidney measurements also did not differ significantly (P=.26). However, the results of the longitudinal kidney measurements differed significantly between the study and control groups, with larger, more realistic values in the study group (right kidney: study group median 105.3 mm, range 86.1-127.1 mm, control group median 92 mm, range 50.4-112.2 mm; P<.001; left kidney: study group median 100.3 mm, range 81.7-118.6 mm, control group median 85.3 mm, range 48.3-113.4 mm; P<.001). Furthermore, whereas all students of the study group obtained valid measurements, students of the control group did not obtain valid measurements of 1 or both kidneys in 7 cases. CONCLUSIONS The newly developed augmented reality ultrasound simulator mobile app provides a useful add-on for ultrasound education and training. Our results indicate that medical students’ use of the mobile app for training purposes improved the quality of kidney measurements.

The most important evaluation criteria for replication methods are availability, performance, consistency, and costs. Performance and response time may be improved by substituting remote data accesses with local data accesses to replicated data. The availability of the system can be increased by using replicated data in case a local failure or disaster should occur. The major disadvantages of data replication are the additional costs of updating replicated data and the problems related to managing the consistency of the replicated data. Tables 1 and 2 give an overview of the evaluation of the replication methods described in this article. Frank (1999) described how such replication overviews may be used to optimize databases in practice. This article evaluates many more replication methods and therefore, it is possible to optimize even more. However, the evaluation criteria previously described have to be subdivided to illustrate the different properties of the different replication methods.
