Abstract:
Abstract To get rid of the current transmission line visual monitoring device which only relies on a single photo-monitoring method, this paper proposes a method based on time-delay estimation and equipment coordinates to locate abnormal sound in the transmission line channel. Firstly, the audio-visual equipment is selected to collect the abnormal sound information of any transmission line as the reference warning record, and the relative time difference between other warning records and the reference warning record is determined. Then, the corresponding audio-visual equipment of the reference alarm record is used as a reference point to set up a Cartesian coordinate system, obtain the GPS information of other audio-visual equipment, unify the GPS information, and get the coordinates of other audio-visual equipment; finally, based on the reference point coordinates, other audio-visual equipment coordinates, and the relative time difference, the transmission channel abnormal sound source coordinates are obtained. Through the experiment of firecracker sound, we can get the firecracker sound within 2km in the open environment, which proves that the location method can effectively enhance the monitoring effect of the transmission channel.

Abstract:
Audio-visual records and archives constitute a fundamental heritage that satisfies multiple needs, including education, training, research and entertainment. As such, there is a need to appropriately preserve and conserve them so they can be accessed for as long as they are needed. In spite of their significant role in safeguarding cultural heritage, audio-visual records and archives, are often neglected and accorded less attention than paper-based records, especially in developing countries. Hence, there is a risk of losing information held in audio-visual form. That is why this study looked at how the National Archives of Zambia (NAZ) and the Zambia National Broadcasting Corporation (ZNBC) preserve audio-visual materials to ensure long-term accessibility of the information. The study investigated the types of audio-visual collections held, the storage equipment used, measures put in place to ensure long-term accessibility of audio-visual materials, the disaster preparedness plans in place to safeguard audio-visual archives and the major challenges encountered in the preservation of audio-visual materials. The findings of the study revealed that films (microfilm and microfiche), photographs and manuscripts, and video (video tapes) and sound recordings (compact cassette) constitute the biggest audio-visual collection preserved. The equipment used to store audio-visual materials included open shelves, specialised cabinets, electronic database for digitised materials, aisle mobiles and cupboards. The measures taken to ensure the long-term accessibility of audio-visual collection included digitisation and migration of endangered records and archives; fumigation of storage areas; conservation of damaged materials and regulation of temperatures and humidity in the storage areas. The disaster preparedness plans in place mostly covered structure insurance; protection against fire and water by way of installing fire extinguishers; smoke sensors; fire detectors and construction of purpose-built structures. The major challenges faced were financial constraints; technological obsolescence; lack of playback equipment; limited training; lack of strong back-up systems and inadequate storage facilities.

Abstract:
This research aims to assess the availability of audiovisual equipment and materials in schools and their practical usage in classroom teaching. The research design used is quantitative descriptive, and the instrument utilized for this research is a questionnaire. The data analysis technique employed is the Miles and Huberman Interactive analysis model. This study was conducted in 5 middle schools, with seven teachers as research subjects. The findings of this research indicate that the status of audiovisual equipment needs to be improved. Computers, televisions, tape recorders, and public address systems are only owned by 64.62% of the schools. Variables such as school management type, school age, school resources, and school strength do not significantly influence the possession of adequate or inadequate equipment in the schools. A total of 87.4% of the schools have effectively used audiovisual equipment. The school administration has yet to make any efforts to properly procure and utilize audiovisual equipment and materials, primarily due to the financial challenges associated with equipment maintenance.

Abstract:
This study investigates the use of audio-visual aids in the EFL classes in Libyan secondary schools. Specifically, it aims to determine how audio-visual aids could work as an excellent motivational instrument for teachers and students in Kufrah secondary schools. Two sets of questionnaires were administered to teachers and students to clarify the needed information. Kufrah secondary schools were chosen for the survey study. 80 students, and 20 teachers were randomly selected. Through the questionnaires made by the researcher, the data was collected, organized and analysed using statistical techniques like percentages. The results of the study revealed that the use of audio-visual aids to develop EFL students seemed to be effective, as indicated by the teachers and students. The results also showed fewer teacher training opportunities in schools and restricted administrative support. The researcher recommends appropriate teacher training, adequate audio-visual equipment and material, and needed administrative support to ensure the optimum use of audio-visual aids, ensuring the learner's maximum benefit.

Abstract:
The purpose of this study is to explore the audio-visual preferences of exercisers in urban forest parks in China and to make practical suggestions for park landscape design. Taking Beigushan Forest Park in Lianyungang City, Jiangsu Province as a case, based on field research and questionnaire survey, this study analyzed the audio-visual preference characteristics of exercisers in the park, revealed the correlation between audio-visual preference and exercisers’ behaviors and individual characteristics, and explored the influence of audio-visual preferences on exercise feelings by establishing a structural equation model. It was found that (1) the forest and its avenue landscape and birdsong are most preferred by exercisers; (2) the audio-visual preferences of people with different exercise forms differ, for example, people who slowly walk, run, and briskly walk have stronger preferences for natural soundscape and visual landscape, while people who use fitness equipment have stronger inclusiveness for human activity sound and prefer public facility-based landscapes. In addition, some individual characteristics such as exercise intensity and exercise frequency significantly affect exercisers’ audio-visual preferences; (3) visual landscape preferences have a greater direct impact on exercise feelings, with natural waterscape having the greatest direct impact, but overall soundscape preferences do not have a high degree of direct impact on exercise feelings, with natural sound still having a strong positive impact. These findings provide a more quantitative basis for the landscape design of urban forest parks from the perspective of exercise behavior.

Thesis submitted in fulfilment of the requirements for the degree Master of Technology: Electrical Engineering in the Faculty of Engineering at the Cape Peninsula University of Technology, 2012
People are spending more time being entertained at home now than ever before. It is currently common to find a home entertainment console containing an LCD or Plasma television, DVD player and surround sound amplifier in many homes. The number of home entertainment devices is increasing, yet our understanding of the effect that they have on power quality is incomplete. This study determines the power consumption of home entertainment equipment as well as the effect that such devices have on harmonic distortion levels. A methodology is developed for the measurement of the power consumption of home entertainment equipment including television sets, DVD players and home theatre. The results are compared to the Energy Star standard to determine if the power consumption of these devices is within the limits imposed. The methodology presented consists of three parts, performing measurements, generating results and comparison to energy and harmonic standards. The developed methodology includes steps for mathematically combining the measured voltage and current waveforms of individual devices. The goal is to determine total current and voltage waveforms for a combination of devices. The methodology also describes how to analyze the resultant synthesized waveforms so as to determine the power consumption at each harmonic. The levels of current harmonics for individual devices and groups of devices are determined and then compared to the EN6100-3-2 standard to ascertain if they are within the limits imposed. The power consumption and current harmonics of each combination as well as individual devices were analysed. Using the developed methodology, four case studies were conducted, grouping different home entertainment devices together. It was found that the power consumption of LCD television sets are below the limits imposed by the Energy Star standard while for Plasma based televisions it was above these limits. Current harmonic levels for CRT based televisions were found to be above the limits imposed by the EN6100-3-2 standard while those for LCD and Plasma based televisions the levels were below the limits. The research concludes that the current harmonics of new LCD and Plasma based televisions does not pose any concern for power quality.

Abstract:
Control oriented local area networks (COLANs) are being installed in factories at an increasing rate. Traditionally, process control has operated with a master scheduler (computer) monitoring a number of points in a control grid. As the complexity of today's process control needs grow, the need to process information locally increases. Microcontrollers, networked with a master scheduler, can collect data from a locus of points and make decisions as to whether the master needs to be notified or not. By processing data locally, memory and execution time are freed up for the master scheduler. Task implementation becomes modular in nature, resulting in process control software that is easier to write, and maintain. This structure is the basis for COLAN V, a low cost, real-time, distributed control network developed at Oregon State University. COLAN V was used as the foundation for the creation of a multi-media presentation system. Six microcontrollers were networked together to remotely control the operation of projectors, projector screens, and lighting. Based on the application the master scheduler was replaced by a tape player. This allowed the storage of the audio part of the presentation on one track of the tape and the storage of the synchronized control signals on the other track. This distributed control network supplied a low cost solution to a need that was not addressed by the commercial market at any price.

Since the structure of Copyright Acts become more complete and the Copyright awareness continues to rise, the Public Broadcast legal issues related to people’s regular life like hotels, schools, hospitals, supermarkets, hopping malls, and others in public places continue to increase. To rebroadcast the original broadcast content in public happens frequently and is not a new Copyright Act issue. Among all the issues, the most common two issues are (1) simply broadcasting the content of the program by turning on the radio/television in public , or (2) via a different broadcasting system of wire, wireless, or other equipment from the original broadcaster, broadcasting the original sounds or images of the program. In addition to the original broadcast content of the program, the information used to produce the show is also protected by Copyright Act. This creates different types of rights and rights owners. Therefore, the operators of those public places might be claimed for charges by different rights owners at loose end. Moreover, the operators might be threatened with the possibility of bearing criminal liability if they could not reach a common consensus with rights owners. A more complete system to response to this kind of pubic broadcast phenomenon could reduce the burden of the operators and help gain proper profits for the right owners. This system could also reduce the complicated interaction among public broadcast rights, public performance rights, and public presentation rights, and further diminish the negative impact in the society. This study is based on the views of Comparative Law to compare the International Covenants with the laws of other countries. By investigating all the legal regulations of Public Broadcast, it is hoped to learn how to improve our Copyright Acts in order to build up a better system.

When globalization the major driving force for business growth, it has become much more important to select appropriate entry timing and target market of an overseas area. This article will use a world-renowned audio and video electronic company as an example to explore the different considerations and corresponding strategies during the different phases of its globalization process. This article analyzes the entry mode of the case company, a multinational audio and video electronic company in the retail industry, in its expanding overseas market, and intends to explain why the company has selected different entry modes in different stages, as well as the impact of the overseas market entry mode on the marketing strategy in the host country from the perspective of the eclectic paradigm. The final section discusses the reason why the role of the branch company in the host country has changed. Case study is the main method used in this study. Aside from data collection, the research process is also based on the comparison of different market entry strategies of multinational corporations and with reference to the eclectic paradigm. The study tries to seek some merits from the globalization progress of the case company. In the end, seven research topics are summarized and relevant research suggestions are presented. Some points are put forward from the study of the six topics. When multinational corporations are entering the overseas market, differentiated products will help develop the market channel in the host country and would seize the market opportunities and gain the profit. When the multinational corporation has abundant experience in internationalization and the advantage of tangible and intangible assets, it tends to enter the market with a high-control mode of direct investment so that it can get hold of the resources of the host country and avoid the operation risk caused by uncertain factors from partners. When the domestic demand is too small and the development potential is not big enough in a regional market, multinational corporations will integrate the regional markets and adjust internal operation modes to utilize the enterprise resources in a most effective way. The study suggests that the multinational corporation well-reputed and owns internationally renowned brands and differentiated products, and its partners in the host country have the ability to develop market channels. Only under such circumstances can the brand of the multinational corporations stand out of numerous local brands and attract consumer’s attention. Before they decide to enter the host country market with the mode of establishing retail channels, multinational corporations should evaluate their internal advantages, including capital, knowledge and experience of management, familiarity with overseas market, sufficient local partners, brand advantage, their own image and retailer system support.

Abstract:
This chapter emphasises that audio-visual (AV) resources are very fragile and need to be stored in ideal conditions to preserve them for posterity. It describes different types of AV materials and the conditions under which they should be kept. It is based on a study that was conducted in the Eastern and Southern Africa Regional Branch of the International Council on Archives (ESARBICA) region. Data were gathered using quantitative and qualitative methods. The results revealed lack of equipment to monitor environmental conditions, absence of policies to govern the acquisition, appraisal, access, preservation, retention, digitisation and disposal of AV materials, and failure to apply the records life cycle (or any model) to AV records. The results point to a need for national archives to develop guidelines that apply to AV materials particularly in Africa. Particular attention should be given to training AV archivists in the region using an integrated curriculum.

Abstract:
The eMentors scheme encapsulates the concept that the person in the home most likely to be able to programme the audio-visual equipment is the teenager. The scheme harnesses the digital generation’s propensity for technology by using the students to teach their teachers how to make appropriate use of electronic resources in the classroom. We present a case study that focuses on both staff and student experiences of the eMentoring system at a further education college in Hertfordshire, UK and outlines the strategy for ongoing staff development and support. The scheme has given lecturers the confidence to develop new technology-enhanced pedagogical practices and has given students the opportunity to play an active part in the development of their own learning environments and to influence policy on the use of technology. We believe that this model has been an effective element in a concerted approach to changing the prevailing attitudes to designing pedagogy for 21st century learners.

Abstract:
Virtual Reality (VR) and Augmented Reality (AR) are becoming useful tools to provide a visual representation of a product, a design or environment without the cost of building a prototype. Other applications include maintenance support, procedures development and workstation design. Currently, VR and AR systems can only display visual and audio cues. For example, in workstation design, i.e., a ship’s bridge, aircraft flight deck, command centre, maintenance facility, etc., it is important to for design engineering to determine if the human operator can reach the gauges, switches and controls. To meet the ergonomic and human factor design criteria, the human operator must easily interact with all the displays, instruments, equipment, and controls. This impacts the design and location of seats, instrument panels and windows. VR and AR devices, such as the controllers and gloves, can track the position of the human hand and fingers in a virtual environment but are not able to detect realistic distance or interference with a virtual object. This paper presents a new VR prototype to allow an operator in a fully immersive environment to reach and touch any object in the virtual world. As a case, study the environment was applied to the cabin design of a medical helicopter. Feedback and suggestions from the medical personnel were obtained and are presented.

Abstract:
Background: Reaction time is required for a muscular reaction to start after an administered stimulus (RT). RT assesses the pace at which the central nervous system analyses sensory information and executes it as a motor response. Our bodies react to various sorts of stimuli at varying rates. It is crucial to have this on hand for everyday and emergencies. Several factors, including gender, age, physical fitness, exhaustion, distraction, and alcohol, have impacted reaction time. This visual and aural reaction time area merits more investigation, specifically the impact of object colour (red), acoustic stimulation (beep tone), and gender. Aims and Objectives: 1) To compare medical students' simple visual and auditory reaction times to red colour and beep tone. 2) To compare female and male medical students' simple visual and auditory reaction times. Materials and Methods: After gaining ethical approval (IEC/GMC/Cat-C/2021/531 dated 24/05/2021) and signing informed consent, all 250 (125 women and 125 men divided into two groups) first-year medical students from the cohort of 2020-21 aged 17 to 20 were selected. Anand Agencies Pune developed RT equipment to record VRT and ART. The data were analysed with the SPSS 26.0 statistical program and the unpaired t-test. Results: Study participants showed a statistically significant difference in their VRT for Red (R) and ART for Tone (T), respectively, with 0.199±0.033 seconds and 0.082±0.009 seconds (p < 0.001). As an added benefit, the variance of men's VRT was substantially more significant than that of women's VRT (p = 0.001), with a mean of 0.192±0.026 seconds for men and 0.206±0.037 seconds for women. In contrast, ART had no discernible gender difference (p=0.246). Conclusion: Our analysis revealed that the VRT for red was substantially higher than the ART for tone. This might be because the visual processing time is longer than the audio. Men also respond faster to VRT than women, although their responses to ART are considerably quicker or equivalent to those of women, which explain why these gender disparities occur

Abstract:
Technologies entered in education since their first appearance and were used both for improving the efficacy and efficiency of traditional teaching and for creating new teaching-learning opportunities (Galliani et al., 1999). The definition “educational technologies” was coined in the 1950s to describe the equipments to be used in teaching-learning controlled environments. The introduction of the computer in teaching led to the definition of “new educational technologies” to mark the overcoming of traditional systems like audio-visual media (i.e., cinema, radio and television) with the new digital medium. In the 1970s the Association for Educational Communications and Technology (AECT) formulated the definition of instructional technology as “… the theory and practice of design, development, utilization, management, and evaluation of processes and resources for learning. ... We can think about it as a discipline devoted to techniques or ways to make learning more efficient based on theory but theory in its broadest sense, not just scientific theory”. The Internet in the 1990s introduced further elements of innovation in the use of technologies for education with an exponential growth of instruments and resources leading to the transition from face to face (f2f) teaching to online teaching-learning experiences. The Internet more than other technological experiences entered in the educational systems all over the world and is today marking a revolution in continuous education and lifelong learning.

Abstract:
Abstract Mechanical equipment, operating in the oil and gas industry produces a wide range of sounds, often culminating in noise. A functional equipment creates a standard sound, while malfunctioning equipment creates an anomalous sound. In this paper, we propose an application of a contrastive learning algorithm to detect anomalous sound amidst industrial noise, which in turn helps in the identification of the malfunctioning equipment on an offshore rig. The recent success of contrastive learning algorithms to detect novelty in visual representation has inspired our work. We hypothesise that for most of its lifetime, equipment operates normally. Instances of malfunction that produce anomalous sound and hazardous consequences are rare in their defined lifetime. To this end, we implement a contrastive learning algorithm to identify similarities between audio clips using 10-second length normal-audio clips collected from 6 different equipment for training purposes. It extracts local and global features from the augmented audio clips and presents them in latent space, where the loss function differentiates between normal and anomalous sound. Finally, we input normal audio and anomalous audio into the algorithm. The performance of the proposed algorithm is measured using Receiver-Operating-Curve - Area-Under-Curve (ROC-AUC) (Koizumi et al., 2020; Nunes, 2021)[5]. It successfully differentiates normal and anomalous audio to achieve an average ROC-AUC of 0.77 on the scale (0-1). 26092 audio clips of normal equipment sound and 6065 audio clips of anomalous sound from Valve, pump, fan, slide-rail etc., are used to perform the proposed experiment. Diverse industrial anomalies produced by unbalanced-voltage change, clogging, leaking, contamination, loose belt, no grease etc., are present in the dataset. The proposed methodology of contrastive learning consists of a data-augmentation module followed by an encoder and a Neural Network (NN). Data augmentation transforms the input audio clip to ensure robust performance. The encoder extracts the features from audio clips and projects them in the space of contrastive loss function with the help of NN. Automatic failure detection using Artificial Intelligence is essential for Industry 4.0. Prompt decision by monitoring sound produced by mechanical equipment holds immense potential for asset maintenance in the petroleum industry. This paper is one of the first instances wherein the application of contrastive learning for the maintenance of mechanical equipment has been demonstrated. The proposed method is a unique approach towards anomaly detection using acoustic-features and it significantly reduces human intervention in hazardous and hard-to-reach environments.

Abstract:
The successful implementation of eVTOL aircraft as a viable mode of future transportation hinges on the inclusion of all passengers, including those with disabilities either visible or hidden. To this end, the graduate design team from Rensselaer Polytechnic Institute propose Oliwhoper, a lift + cruise multicopter universally designed for all passengers. Oliwhoper takes on a universal design approach, where accommodations for those with disabilities are used to enhance the ride experience for everyone. A spacious cabin with carefully designed lighting, hand-holds and audio cues makes it easy for anyone with mobility, visual or auditory challenges to safely and easily ride in comfort. These vehicle design features make Oliwhoper accessible to passengers with reduced mobility, allowing for operators to flexibly service customers in a variety of locations, without the need for specialized ground equipment. Operators will also enjoy Oliwhoper's efficient lift + cruise design which maximizes the performance advantages of distributed electric propulsion, while maintaining the redundancy and control authority expected from modern aircraft.

Abstract:
The COVID-19 pandemics greatly affected teaching methods and tools. In the last two years the teaching method switched from face-to-face to online or hybrid and later on, to face-to-face again. This paper presents the results of the experience carried out in the lab-sessions of Materials Science subject within the Degree in Engineering in Industrial Design and Product Development, taught at the Higher Technical School of Design Engineering of the Universitat politècnica de València. The aim of this work is to develop an audio-visual teaching tool to be used during the course, to aid students understand the experimental procedures and the use of laboratory equipment in order to increase their academic performance. For this purpose, the obligatory didactic videos employed to undertake the laboratory session during the pandemics, when the students participated remotely, were processed and employed in a shorter version as an optional TIC tool during the last academic course. The student satisfaction towards the utility of didactic videos was measured by using an individual questionnaire. A comparison between the academic performance during pre- and post-pandemics was performed, as well.

Abstract:
Abstract The energy industry operates in a world where a consistent connection over real-time information is expected, however, less than 1% of available data sets are currently leveraged in the industry and usually – when monitored – most of the evaluations are based on human assessment of raw data. Today's business complexity requires an evolution in the way we share project and service information in the energy industry – from a reporting culture to true transparency and collaboration. There is a need for a digital system able to embrace raw data, perform analytics, and display key recommendations and insights. This will play a key role in turning challenges into opportunities. Adopting a real-time modular platform for proactive asset management and instant troubleshooting can be leveraged during any stage in a field's life cycle. Built for collaboration, the platform unlocks value through minimizing equipment downtime, enabling proactive servicing and digitally optimizing the understanding of equipment needs throughout the life of field. This agile approach consolidates multiple data streams into one trusted digital source including:Autonomous monitoring of subsea wells, wellheads and xmas tree integrity without the need for active power. Designed to integrate with existing subsea infrastructure, these battery-operated monitoring systems passively monitor for a breach of material and will alert the operator of any integrity issues.A fully equipped remote communications tool that goes beyond simple audio and video chat to support effective remote support.Integrated visualization of robotic cleaning and inspection data of subsea equipment.Objective view of the overall health status asset(s), field(s) or infrastructure, considering those elements which have the greatest bearing on health and longevity, with the possibility to monitor health trends over time, prolong operable life and optimize productivity. The implementation of the right tool, feature-rich, intuitive, and easily scalable leverages data and analytics to unlock a collaborative model of proactive servicing, prolong asset operable life and reduce OPEX. The case study demonstrates the positive outcomes that can aid the decarbonization of monitoring operations in remote locations. This approach can yield exceptional cost savings when compared to traditional methods of on-site visual monitoring. A wider overview will include the benefits of extending the window for full intervention or P&A, including lower asset risk, and protecting the environment. This paper illustrates deployment examples of the platform on subsea fields in the North Sea and Asia, its value, approach, as well as recommendations for any operator willing to embark on a similar journey.
