Following the path set out by the “Argus” project, video monitoring stations have become a very popular low cost tool to continuously monitor beaches around the world. For these stations to be able to offer quantitative results, the cameras must be calibrated. Cameras are typically calibrated when installed, and, at best, extrinsic calibrations are performed from time to time. However, intra-day variations of camera calibration parameters due to thermal factors, or other kinds of uncontrolled movements, have been shown to introduce significant errors when transforming the pixels to real world coordinates. Departing from well-known feature detection and matching algorithms from computer vision, this paper presents a methodology to automatically calibrate cameras, in the intra-day time scale, from a small number of manually calibrated images. For the three cameras analyzed here, the proposed methodology allows for automatic calibration of >90% of the images in favorable conditions (images with many fixed features) and ∼40% in the worst conditioned camera (almost featureless images). The results can be improved by increasing the number of manually calibrated images. Further, the procedure provides the user with two values that allow for the assessment of the expected quality of each automatic calibration. The proposed methodology, here applied to Argus-like stations, is applicable e.g., in CoastSnap sites, where each image corresponds to a different camera.

Water is a fundamental necessity of life. Yet water supply and distribution networks the world over are old and lacking in adequate maintenance. Consequently they often leak as much water as they deliver and provide an unacceptable quality of service to the customer. In certain parts of the world, water is available only for a few hours of the day. The solution is to build a mathematical model to simulate the operation of the real network in all of its key elements and apply it to optimise its operation. To be of value, the results of the model must be compared with field data. This process is known as calibration and is an essential element in the construction of an accurate model. This paper outlines the optimum approach to building and calibrating a mathematical model and how it can be applied to automatic calibration systems.

The use of video-monitoring techniques is significantly increased due to the diffusion of high-resolution cameras at relatively low-costs and they are largely used to estimate the shoreline evolution and wave run-up, as important coastal state indicators to be monitored and predicted for the assessment of flooding and erosion risks. In this work, we present an integrated approach based on the results from the low-cost video monitoring systems and the numerical modeling chain by means of SWAN and XBeach to accurately simulate and predict the swash zone processes.Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/nLGNneJzmIU

The promise of the Internet for cartography has faded into stark realities of commercialism, connectivity problems and confusion about what represents quality in Internet mapping. Accessing the Internet is still problematic and a great digital divide separates the developed from the developing world. Interaction with the online map, the single greatest advantage of maps and the new medium, has been either poorly implemented or not incorporated at all. The commercial aspect of the Internet has been turned upside down. We pay to access the Internet, not for its content. As a result, there is little competition to improve the quality of online maps, other than for bragging rights, and little incentive to create quality content. On top of this, in many parts of the world, access to the Internet by computer is expensive or inconvenient and people prefer to use the Internet through their mobile phone. Almost all new users to the Internet are connecting through mobile devices and a small screen that is hardly suitable for the display of maps. While a de-centralized system like the Internet is impossible to fix in traditional ways, solutions must be found for making the medium more accessible and useful for maps. National and international organizations can play a key role in providing examples of what is possible with maps and the Internet. Low-cost, easy-to-use tools also need to be made available so that online cartographers can create quality content.

Significance. The professional activity of nurses in multi-specialty hospitals includes a wide range of responsibilities with a high shift load, which can result in lower quality of care delivery to seriously ill (low-mobility) patients. At the same time, digital technologies are yet to be widely used in the professional activities of inpatient nurses, which serves basis for improving care delivery to seriously ill (low-mobility) patients through digital technologies and video monitoring systems. The purpose of the study: to assess readiness of nurses to the introduction of digital technologies and video monitoring systems in care delivery to seriously ill (low-mobility) patients. Material and methods: a study on readiness of nursing staff to the introduction of digital technologies and video monitoring systems in care delivery to seriously ill (low-mobility) patients was implemented (n=565). The analysis was carried out on the basis of descriptive statistics methods. The significance level is set equal to p<0.05. Results. The study shows that almost every fifth nurse 19.0% ±1.65% (CI 15.7% - 22.30%) is ready to carry out professional activities for seriously ill (low-mobility) patients under the control of a video monitoring system in order to improve quality of care delivery; almost every fifth nurse 19.9%±1.68% (CI 16.54% -23.26%) considers it possible to evaluate quality of care delivery to seriously ill (low-mobility) patients using digital technologies (surveillance systems, video cameras. Conclusions. Nurses of medical organizations (hospitals) are not always ready for the use of digital technologies and introduction of the round-the-clock video monitoring system, however they show readiness if quality of care to patients improves. Keywords: digital technologies; modern methods to monitor work of nurses; nursing; professional activities of nurses.

Video Systems

The use of shore-based video systems has become a very popular and accessible low-cost tool for coastal monitoring given their capability to deliver continuous and high-resolution temporal data over large enough spatial scales. However, the reliability of the final image products can be compromised by external factors, sometimes overlooked, that can alter the image geometry over time. In particular, unwanted camera movement, produced either by thermal or mechanical effects, can lead to significant geo-rectification errors if not properly corrected. This study addresses an alternative straightforward method to stabilize an either continuous or subsampled image sequence based on state-of-the-art techniques and available routines.Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/xX1CrvPQpK8

And Training

Computerized auditory training (CAT) is a convenient, low-cost approach to improving communication of individuals with hearing loss or other communicative disorders. A number of CAT programs are being marketed to patients and audiologists. The present literature review is an examination of evidence for the effectiveness of CAT in improving speech perception in adults with hearing impairments. Six current CAT programs, used in 9 published studies, were reviewed. In all 9 studies, some benefit of CAT for speech perception was demonstrated. Although these results are encouraging, the overall quality of available evidence remains low, and many programs currently on the market have not yet been evaluated. Thus, caution is needed when selecting CAT programs for specific patients. It is hoped that future researchers will (a) examine a greater number of CAT programs using more rigorous experimental designs, (b) determine which program features and training regimens are most effective, and (c) indicate which patients may benefit from CAT the most.

Currently, the problem of early rehabilitation of stroke patients is important, since in terms of the prevalence of cerebrovascular diseases and disability after suffering a stroke, Russia is one of the first places in the world. The complex of medical rehabilitation of such patients should provide for the early and most complete restoration of all body functions, patient education for lost skills, re-socialization of the patient and improvement of the quality of life. One of the factors contributing to a significant reduction in the quality of life after a stroke is the development of chronic constipation. The article reflects the modern methods of correction of chronic constipation in patients with limited mobility.
