Abstract:
In this study, we focused on the formalization of video frame descriptions in the context of solving video segmentation problem. Since native video data can have various sizes, dividing each frame into blocks allows present image frame as a square matrix for a formal description. The frame block is a matrix of arbitrary dimensions. The ability to skip the step of matrix transformation to a square dimension or vectorization using some descriptor allows to reduce computational costs, freeing up computational resources required for this transformation. In our study, we used Ky Fan norm value as image frame block descriptor. The Ky Fan norm is built on top of matrix singular values. A singular decomposition does not impose restrictions on either the dimension orthe character of the elements of the original matrix. We conducted a comparative analysis of the effectiveness of the obtained descriptor for different video data sizesand with different aspect ratios, showing that the change in the descriptor for each block is independent of the video sizeand aspect ratios. Changes in the descriptorsfor each block from frame to frame are identical for video data of varying sizes. This means that as a result of such fragment transform, a square matrix of a fixed size iscreated, regardless of the output video size.This makes it possible to unify further processing of the video, which can be useful for the task of information search in large video databases under the conditions of providing a query "ad exemplum". In thiscase, we can analyze the existing database in offline mode and match each video with a fixed square matrix of descriptors, which will significantly reduce the time and amount of resources when matching with the query. Also, this approach can be effectively used to analyze video data for the motion detection and scene change tracking.

Abstract:
Aim(s)This exploratory research aimed toexplorethe views of education setting staff who have undertaken an Analysis of Additional Needs Screening Tool (AANT) online assessment and consultation with an Educational Psychologist (EP). Initially, education staff complete the online AANT form, comprising a range of solution-oriented questions about the child or young person’s strengths and difficulties. This is followed by a consultation with an EP. Whilst the EP service now utilises video conferencing applications, at the time of this research the consultation was undertaken either face-to-face (F2F) or using the telephone. The research questions centred around the importance of hearing the experiences of education staff as consultees within the AANT process, and how their views might inform further development of the AANT consultation process.Method/RationaleThis exploratory study involved two phases. The first involved three F2F semi-structured interviews with staff who had taken part in both F2F and telephone EP consultation, after having completed the AANT online assessment. This led to phase two which asked specific questions of 46 education staff via a semi-structured telephone conversation with a member of the Local Authority (LA) Psychology & Therapeutic Services (P&TS). The EP Service sits within the P&TS.FindingsThe findings in phase one identified predominant themes relating to the EP Service, how education setting staff engage with and feel about the AANT, the AANT process and AANT outcomes. Broad indicators from this exploratory research are that staff found the AANT process useful and both EP consultation models acceptable and effective. The findings informed further development work in the EP Service.LimitationsThis work was undertaken within one LA and therefore represents a small, but encouraging, geographical sample.ConclusionsAnalysis of the findings helped the LA EP Service to develop the AANT online digital platform which enables effective remote consultation with education setting staff alongside a traditional F2F service delivery model. The level of enthusiastic uptake and positive feedback from educational settings for all ages has exceeded all expectation. The findings extend the evidence base around the use of digital assessment methods and telephone consultation.

Abstract:
As children’s actual aquatic skills are important for the prevention of drowning as well as their engagement in lifelong aquatic physical activity, researchers and practitioners should be able to assess this vital concept accurately and reliably. Therefore, this study aimed to investigate the inter-rater and intra-rater reliability of the Actual Aquatic Skills Test (AAST), consisting of 17 different test items for the assessment of young children’s motor competence in the water. Six raters received a training and evaluation session on scoring the AAST, after which five of them assessed four test videos (of various children (n = 38) performing the test items) twice, with one to two weeks in between (i.e., test and re-test). Inter-rater and intra-rater reliability were determined per test video and for the different AAST test items across videos using Gwet’s Agreement Coefficient 2 (Gwet’s AC2). The Gwet’s AC2 for inter-rater reliability at the test varied from 0.414 to 1.000, indicating a moderate to perfect agreement between raters. For intra-rater reliability, it ranged from 0.628 to 1.000, demonstrating a good to perfect agreement between test and re-test scoring. In conclusion, the AAST is a promising tool to reliably assess young children’s actual aquatic skills in an indoor swimming pool.

Abstract:
The COVID-19 pandemic is having a huge impact on people and communities. Many organizations face significant disruptions and issues that require immediate response and resolution. Social distancing, breathing masks and eye protection as preventive measures against the spread of COVID-19 in the absence of an effective antiviral vaccine play an important role. Banning unmasked shopping in supermarkets and shopping malls is mandatory in most countries. However, with a large number of buyers, the security is not able to check the presence of breathing masks on everyone. It is necessary to introduce intelligent automation tools to help the work of security. In this regard, the paper proposes an up-to-date solution – an intelligent system for identifying people without breathing masks. The proposed intelligent system works in conjunction with a video surveillance system. A video surveillance sys-tem has a structure that includes video cameras, recorders (hard disk drives) and monitors. Video cameras shoot sales areas and transmit the video image to recording devices, which, in turn, record what is happening and display the video from the cameras di-rectly on the monitor. The main idea of the proposed solution is the use of an intelligent system for classifying images periodically received from cameras of a video surveillance system. The developed classifier divides the image stream into two classes. The first class is “a person in a breathing mask” and the second is “a person without a breathing mask”. When an image of the second class appears, that is, a person who has removed a breathing mask or entered a supermarket without a breathing mask, the security service will immediately receive a message indicating the problem area. The intelligent system for image classification is based on a convo-lution neural network VGG-16. In practice, this architecture shows good results in the classification of images with great similarity. To train the neural network model, the Google Colab cloud service was used – this is a free service based on Jupyter Notebook. The trained model is based on an open source machine learning platform TensorFlow. The effectiveness of the proposed solution is con-firmed by the correct processing of the practically obtained dataset. The classification accuracy is up to 90 %.

Abstract:
An artillery shot is accompanied by the release of combustion products of powder gases from the barrel. It is proposed to usemuzzle ejection to classify the level of barrel wear during firing. A full-scale experiment was carried out with high-speed video recording in the visible and infrared ranges of the dynamics of the development of muzzle ejection when firing guns with a defect-free and worn barrel. Muzzle ejection when fired from a large-caliber gun consists of three spatial regions: frontal and two side, associated with the emission of powder gases through the openings of the compensators. A technique for analyzing three synchronized video streams has been developed. The technique made it possible to quite fully investigate the processes of muzzle ejectiondevelopment dynamics in defect-free and worn barrels. Informative signs are chosen, which are different for the dynamics of muzzle ejection from defect-free and worn barrels. This madeit possible to build a binary classifier of the condition of the trunks by the level of wear based on the support vector machine with least squares. In contrast to the classical SVM classifier, thisallowed us to reduce the calculation time and reduce the required size of the training set. To assess the quality of classification, it is proposed to rely on only errors of the first and second kind, but also an integral indicator –the probability of error-free classification. To increase the reliability of the classification, the concept of a universal binary classifier is proposed, which uses both video recording of the muzzle ejection and acoustic fields of the shot –ballistic and muzzle waves –to diagnose the state of the barrel. On the basis of experimental data, it is shown that the use of all physical fields accompanying an artillery shot for the binary SVM classification allows obtaining a high value of the error-free classification probability.

Abstract:
Interactive video technology is regarded as the latest addition to the already large number of instructional media which may benefit education. Interactive video was developed as a combination of video technology, laser technology and computer technology. In education, these technologies occur in a large variety of configurations. Thus, a basic video recorder and monitor can be interactively integrated in lessons by the manner in which the teacher controls this apparatus. In contrast, the most advanced configuration of interactive video consists of a microprocessor, video monitor and laser disc drive. The advantage of the latter is the complete interaction which can be achieved in lessons (a one on one relationship between the learner and the technology). Besides the large number of configurations in which interactive video technology occurs, this research has also pointed out how interactive video could have a reinforcing effect on the most widely recognised didactic principles in an educationally responsible manner. The advantages and disadvantages of computer and video technology are indicated separately in order to arrive at the beneficial characteristics of interactive video where education is concerned. These advantages include aspects such as: the promotion of self-activity, individualisation, controlling the rate at which the teaching and learning process takes place and the complete control over image and sound. Instructional methods such as demonstrations, programmed teaching and simulations are those aspects of teaching which benefit from the technologies in question. Aspects mentioned in the previous paragraph, were determined by means of a literature study. The reliability of this information was practically tested by means of a structured questionnaire which was presented for completion to thirty eight (38) institutions. The purpose of this empirical section of the study was to confirm/not confirm the results of the literature study.

Abstract:
In an effort to increase the number of wheels with measured profile parameters and reduce the number of condemnable wheels in service, machine vision-based wayside inspection systems are being developed to “virtually” gage all wheels of passing trains. In 2003, Transportation Technology Center, Inc. (TTCI), a wholly owned subsidiary of the Association of American Railroads (AAR), evaluated a pair of these wheel profile monitoring systems from two different vendors. Wheel-related expenses (inspection, maintenance, and replacement) make up about 37 percent of annual car maintenance costs. A significant portion of these expenses is directly related to maintenance actions associated with worn wheels. The primary indicators of worn wheels are wheel profile parameters that reach condemnable limits imposed by industry maintenance standards. These parameters include flange thickness, flange height, rim thickness, and tread hollow (hollow-worn wheels). To monitor profile parameters, inspectors attempt to visually check each wheel on inbound and outbound trains. They also measure wheel profile parameter values with steel gages on about 5 percent of the wheels annually. Each system TTCI evaluated used a different method to measure wheel profiles and determine the four primary parameters of interest. One system used lasers to highlight the wheel profile, and the other used high intensity strobes to take a picture of the wheel. Both systems used video frame capture technology and proprietary algorithms to analyze the data and calculate profile parameters. Both systems were installed at wayside locations at the Federal Railroad Administration’s Transportation Technology Center (TTC), Pueblo, Colorado. The systems were set up and evaluated over a period of several months. For each system evaluation, a test consist was assembled and run by the system at various speeds and lighting conditions. The profiles for test wheels were measured with a MiniProf® profilometer, and the four primary profile parameters were determined for each wheel prior to testing. Both systems were used during the tests to measure the wheel profiles and associated profile parameters. Through subsequent analysis, the system-derived parameters were compared to MiniProf parameter values for each test wheel to determine the tested system measurement accuracy. Both systems were found to be capable of delivering measurement accuracies of greater than 90 percent for three of the four parameters.

Abstract:
In modern aero engines the lubrication system plays a key role due to the demand for high reliability. Oil is used not only for the lubrication of bearings, gears or seals, but it also removes large amounts of the generated heat. Also, air from the compressor at elevated temperature is used for sealing the bearing chambers and additional heat is introduced into the oil through radiation, conduction and convection from the surroundings. The impact of excessive heat on the oil may lead to severe engine safety and reliability problems which can range from oil coking (carbon formation) to oil fires. Coking may lead to a gradual blockage of the oil tubes and subsequently increase the internal bearing chamber pressure. As a consequence, oil may migrate through the seals into the turbo machinery and cause contamination of the cabin air or ignite and cause failure of the engine. It is therefore very important for the oil system designer to be capable to predict the system’s functionality. Coking or oil ignition may occur not only inside the bearing chamber but also in the oil pipes which carry away the air and oil mixture from the bearing chamber. Bearing chambers usually have one pipe (vent pipe) at the top of the chamber and also one pipe (scavenge pipe) at the bottom which is attached to a scavenge pump. The vent pipe enables most of the sealing air to escape thus avoid over-pressurization in the bearing compartment. In a bearing chamber sealing air is the dominant medium in terms of volume occupation and also the in terms of causing expansion phenomena. The scavenge pipe carries away most of the oil from the bearing chamber but some air is also carried away. The heat transfer in vent pipes was investigated by Busam [1], [2]. Busam has experimentally developed a Nusselt number correlation for an annular flow in a vent pipe. For the heat transfer predictions in scavenge pipes no particular Nusselt number correlation exist. This paper intends to close the gap in this area. As part of the European Union funded research programme ELUBSYS (Engine LUBrication System TechnologieS), an attempt was done to simplify the oil system’s architecture. In order to better understand the flow in scavenge pipes, high speed video was taken in two sections of the pipe (vertical and horizontal). In the vertical section the flow was a wavy annular falling film whereas the flow in the horizontal section was a an unsteady wavy stratified/slug flow. Heat transfer has been investigated in the horizontal section of the scavenge pipe, leaving the investigation on the vertical section for later. Thanks to the provided extensive instrumentation, the thermal field in, on and around the pipe was recorded, evaluated and also numerically modeled using ANSYS CFX version 14 [23]. Brand new correlations for two-phase flow heat transfer (Nusselt number) and for pressure drop (friction coefficient) in horizontal scavenge pipes are the result of this work. The Nusselt number correlation has been developed in such a way that smooth transition (i.e. no discontinuity) from two-phase into single phase flow is observed. This work was funded and conducted within the 7th EU Frame Programme for Aeronautics and Transport (AAT.2008.4.2.3).
