Aircraft noise calculation and synthesis in a non-standard atmosphere

The atmosphere modifies the emitted sound waves of an aircraft during propagation and is therefore important in the calculation of noise contours or synthesis. Noise contours present the resulting noise levels on the ground and are, as such, often applied for regulatory purposes. Aircraft noise synthesis is a technique that allows to transform a calculated prediction into audible sound that can be experienced in a virtual reality environment. Noise synthesis techniques allow people to be subjected to aircraft, routes or procedures that are still being designed. This dissertation describes recent research to improve the modeling of atmospheric propagation effects in aircraft noise contours as well as aircraft noise synthesis. Multi-event noise contours are usually calculated with standardized models that take non-standard propagation into account in an empirical fashion. A propagation algorithm was developed to augment such a model. Signal processing steps can be applied to transform a source noise prediction into an audible result. Furthermore, such steps can be utilized to apply propagation effects to a source noise signal. For a non-standard atmosphere this is not trivial. The role of a non-standard atmosphere is described by a dedicated simulation framework developed in this dissertation. The framework is applied to a flyover to demonstrate the effects associated with multiple ray paths and shadow zones. Besides demonstrating non-standard atmospheric effects, the framework was used to create synthesized results of actual flyovers near an airport. Subsequently, a comparison between measured results and synthesized results was executed. Furthermore, a method was designed to include the effect of turbulence-induced coherence loss of the direct and ground reflected ray in noise synthesis.
Forecasting the Indian Ocean Dipole With Deep Learning Techniques

In the present research, Indian Ocean Dipole (IOD) prediction was explored using statistical methods based on deep learning techniques. First, convolutional neural network (CNN) models were trained using sea‐surface temperature anomaly (SSTA) maps of the Indian Ocean from 1854 to 1989, and the properly trained CNN models were then validated with the period from 1991 to 2019. The results indicate that the deep learning approach is capable of forecasting the IOD at lead times up to 7 months. The forecast skills of CNN are superior to those of the dynamic models in the North American Multi‐Model Ensemble (NMME). The CNN outperforms the NMME with lower sensitivity to predictability barriers and fewer systematic errors. Moreover, the gradient heat map analysis demonstrates that the triggering precursors selected by CNN models for IOD events are novel and physically sensible. These results suggest the CNN to be a new and effective tool for both IOD prediction and comprehension.
Empowering Early Childhood Pre-Service Teachers with Tech Fluency

Many early childhood pre-service teachers will bring some experience with technology into college which may include word processing, gaming, and social media. Some will have a knowledge of block or html programming.Working adult students often bring less experience. Technology in a 21st century elementary classroom integrates technology tools intentionally and ethically. Teachers need to be able to adapt to new technologies and coding languages quickly. Teachers need to embrace the interdisciplinary nature of Science- Technology-Engineering-Mathematics (STEM). A complex myriad of tools and strategies exist. This can seem overwhelming and disconnected from the individual disciplinary goals in the classroom. Pre-service teacher preparation programs must empower pre-service teachers with technology fluency in order to respond to fluid and diverse challenges of the 21st century classroom. This exploratory research project synthesizes pedagogy, international technology standards, peer groups, technology trainings, student evaluations, growth mindset theory, and common readers to reform a small liberal arts college’s approach to early childhood pre-service teacher preparation. The curriculum revision was guided by these questions: 1) How do our pre-service teachers relate to the present and future worlds of themselves and of their students? 2) How can pre-services programs empower early childhood teachers with tech fluency? The exploration involved undergraduate pre-service teachers over a 6-year period. The research resulted in a five-phase approach to educational technology that consists of Play, Learn, Create, Plan, and Share. Pre-service teachers explore technology tools, learn how they work, create innovative robots and projects from the tools, plan curricula that integrate those tools, and develop agency through sharing their thinking, curricula, and projects with the broader educational community. This approach can offer innovative systemic changes in education technology pedagogy.
Bayesian Non-Parametric Estimation in Proportional Hazard Models: Survival Data Analysis with WinBUGS

In survival analysis, the proportional hazard model (PHM) was introduced by Cox (1972) in order to estimate the effects of different covariates influencing the times-to-event data. The PHM has been used extensively in biomedicine, reliability engineering and, recently, interest in its application in different areas of knowledge (e.g., social, economic, actuarial sciences) has increased. However, PHM makes a number of assumptions, which may be violated. In contrast to PHM, the additive hazard models (AHM) assume that the hazard function is the sum of, rather than the product of, the baseline hazard function and a non-negative function of covariates.The survival data may include studies having another source of heterogeneous items; that is, the items under study are dissimilar with respect to some factors other than covariates. Such factors have been referred to as frailty. In general, the frailty models in survival data deal with the unobserved heterogeneity among items under study.In this thesis, both Bayesian and non Bayesian approaches to the estimation of the parameters in the PHM and AHM are reviewed. Development of estimation of PHM and AHM parameters using hierarchical construction are introduced in chapter IV. The methodologies developed are exemplified with two illustrated well-known dataset. Frailty concept is introduced using probabilistic model. The implication in introducing such concept in the estimation process and model validity are given in chapter V. Non-parametric Bayesian is also discussed and implemented in the analysis of PHM. An illustrated example is provided.Since the implementation of Bayesian approaches that obtaining the posterior distribution often requires the integration of high-dimensional functions, a Marcov Chain Monte Carlo (MCMC) is used to compute the features of such posterior distributions for the parameters of interest. Hence, this thesis demonstrates how both AHM and PHM can be implemented by means of MCMC methods using the software WinBUGS.Finally, in chapter VI, a collected dataset from "Insurance Industry" studding the suitable premiums should have paid from an insured to an insurer has been investigated used the survival data analysis.

Technology and industrial development in Japan : building capabilities by learning, innovation, and public policy

Japan was the first major non-western nation to take on board the Western technological and organizational advances of the century after the fist industrial revolution. It subsequently proved fully able to exploit and contribute to the broad, sustained technological advances that began in the twentieth century, as science became harnessed to technology. Japan's economic development remains a model for many technologically less advanced countries which have not yet mastered modern technology to organizational forms; and a knowledge of Japanese technological and economic history can contribute importantly to our understanding of economic growth in the modern era. This book studies the industrial development of Japan since the mid-nineteenth century, with particular emphasis on how the various industries built technological capabilities. The Japanese were extraordinarily creative in seraching out and learning to use modern technologies, and the authors investigate the emergence of entrepreneurs who began new and risky businesses, how the business organizations evolved to cope with changing technological conditions, and how the managers, engineers and workers acquired organizational and technological skills through technology importation, learning-by-doing, and their own R&D activities. The book investigates the interaction between private entrepreneural activities and public policy, through a general examination of economic and industrial development, a study of the evolution of management systems, and six industrial case studies: textiles, iron and steel, electrical and communications equipment, automobiles, shipbuilding and aircraft, and pharmaceuticals. the authors show how the Japanese government has played an important supportive role in the continuing innovation, without being a substitute for aggressive business enterprise constantly venturing into unfamiliar terrains.
High and Low Road Approaches to the Management of Human Resources: An Examination of the Relationship between Business Strategy, Human Resource Management and High Performance Work Practices

The Contingency approach to human resource management leads to the hypothesis that High Performance Work Practices (HPWP) are more compatible with 'High Road' business strategies that emphasize product differentiation through quality and innovation. More traditional human resource management is better suited to 'Low Road' business strategies that emphasise cost control and competition based primarily on price. Using data collected from a sample of 179 large Australian workplaces we tested the contingencies that influence HPWP implementation and impact. Our results support the Contingency approach in that High Road organisations are more likely to adopt HPWP and the Universal approach in that both High and Low Road organisations derive equal benefit from the implementation of HPWP. High Road organisations may be more likely to adopt HPWP because they see more benefit from their introduction or they may find it easier to implement HPWP because they have a less prohibitive union presence, a theory Y management attitude and a longer-term time horizon.

Abstract

In this paper, a review is made of the knowledge about magnetorheological fluids which are part of the class of intelligent materials. These are the fluids that do not comply with Newton's law, their energization being realized through an external magnetic field. Essentially, magnetorheological fluid is a synthetic solution based on hydrocarbons, populated with soft magnetic particles (easy to magnetize and demagnetize). Shock absorbers that use magnetic fluids are found in the automotive industry for vibration pick-up. The shock absorber with elastic element and magnetorheological fluid presents the following advantages: the possibility of electric control of the stroke and the speed of response of the piston-cylinder system, by a contactless method; it has a simple and reliable construction; the proposed shock absorber is a watertight construction; no internal sealing elements compatible with the magnetorheological fluid are required; the shock absorber does not have components with relative movement at the level of the control element, reducing frictional forces.

The Relationship Between Physical Activity Levels of the School of Physical Education and Sports Students and Their Life Satisfaction

This study aims to investigate the correlations between the physical activity levels of students who study sports sciences and their life satisfaction levels according to a number of variables. The study group was composed of 212 students—100 of whom were female and 112 of whom were male—who attended Physical Education and Sports School of Adıyaman University in 2020-2021 academic year.The participants were given the international physical activity questionnaire (Craig et al., 2003) and satisfaction with life scale (SWLS) (Diener & Griffin, 1985) along with personal information form (IPAQ-SF) online.As a result, no correlations were found between physical education and sports school students’ levels of physical activities and their life satisfaction. Accordingly, the BMI average for the female students (x̄ = 20.31) was found to be significantly lower than the average for the male students (x̄ = 23.68). The inactive students’ average (x̄ = 21.61) and the average of the students who were very active (x̄ = 21.37) were significantly higher (p < 0.01). On the other hand, no significant differences were found in the participants’ levels of physical activity or in their life satisfaction levels according to types of sports and gender (p > 0.05). In conclusion, it may be stated that physical activities do not affect university students’ life satisfaction but that they eliminate their problems of overweight and that those activities reduce the average for BMI in positive ways and thus resulted in healthier individuals.
From appraisal interview to staff development discussion: Practice, training and theory

Abstract This paper describes the development of a policy for annual staff development discussions at the University of Otago. In particular, note is made of how the system developed and how it differs from many other forms of annual appraisal interview. In order to underline the difference, brief mention is made of the review and appraisal procedures which were developed alongside the policy for staff development discussions. The role of training is outlined too, as training is considered to be important in attempting to ensure that the intention of the scheme is fully appreciated and followed through. Finally, the way in which a policy for staff development discussions was developed will be located within wider arguments concerning corporate versus collegial views of policy formation and intent with respect to academic staff.
International Recruitment in Canadian Higher Education: Factors Influencing Students’ Perceptions and Experiences with Education Agents

Education agents, also known as college counsellors or third-party recruiters, have been used extensively by Canadian higher education institutions (HEIs) to recruit international students. Unfortunately, little research to date has focused on international students in Canadian HEIs regarding agent practices. This study investigated Canada-bound international students’ perceptions of and experiences with education agents. A survey consisting of two scales was used to gather data. A total of 385 participants representing 59 countries responded to the survey. Findings revealed that nearly half of the participants used education agents during their application, but their general perceptions of and specific experiences with agents were less than satisfactory. This study also identified a few characteristics of international students that might help Canadian HEIs improve the efficiency of their recruitment practices and policies.
Personalised health education against the health damage of COVID-19 epidemic in Hungary (PROACTIVE-19): protocol of an adaptive randomised controlled clinical trial.

Background: Early reports indicate that COVID-19 may require intensive care unit (ICU) admission in 5-26% and overall mortality can rise to 11% of the recognized cases, particularly affecting the elderly. There is a lack of evidence-based targeted pharmacological therapy for prevention and treatment alike. We aim to compare the effects of a World Health Organisation (WHO) recommendations’ based education and a personalised complex preventive lifestyle intervention package (based on the same WHO recommendation) on the outcomes of the COVID-19.Methods: PROACTIVE-19 is a pragmatic, randomized controlled clinical trial with adaptive “sample size re-estimation” design. Hungarian population over the age of 60 years without confirmed COVID-19 will be approached to participate in a telephone health assessment and lifestyle counselling voluntarily. Volunteers will be randomized into two groups: (A) general health education; (B) personalized health education. Participants will go through questioning and recommendation in 5 fields: (1) mental health, (2) smoking habits, (3) physical activity, (4) dietary habits, (5) alcohol consumption. Both groups A and B will receive the same line of questioning to assess habits concerning these topics. Assessment will be done weekly during the first month, every second week in the second month, then monthly. The composite primary endpoint will include the rate of ICU admission, hospital admission (longer han 48 hours) and mortality in COVID-19 positive cases. The estimated sample size is 3788 subjects per study arm. The planned duration of the follow-up is a minimum of one year.Discussion: These interventions may boost the body’s cardiovascular and pulmonary reserve capacities, leading to improved resistance against the damage caused by COVID-19. Consequently, lifestyle changes can reduce the incidence of life-threatening conditions and attenuate the detrimental effects of the pandemic seriously affecting the older population. Trial registration: The study has been approved by the Scientific and Research Ethics Committee of the Hungarian Medical Research Council (IV/2428- 2 /2020/EKU) and has been registered at clinicaltrials.gov (NCT04321928) on 25 March, 2020.

The experiment involved 100 participants, both men and women in the ages 18-66 years, who individually evacuated a smoke-filled rail tunnel of approximately 200 metres length. The main purpose of the experiment was to collect and derive data on human behaviour and movement speeds, and to study the effectiveness of different technical emergency exit installations, systems and designs. In the report, an extensive description of the set-up, design and execution of the experiment is given. In addition, a thorough account of the analysis and outcome of the analysis is presented. Finally, a discussion is made and general recommendations and conclusions are presented. (Less)
How Are Teachers Educating Students with Disabilities During the Pandemic?

• Most teachers were less confident in their capacity to meet the requirements of their students’ Individualized Education Programs (IEPs) when teaching remotely. T he coronavirus disease 2019 (COVID-19) pandemic has led to major disruptions in the way that teachers educate students with disabilities (SWD). 1 In March 2020, as schools closed, disabilities rights advocates, teachers, and families expressed concern that SWD would be affected disproportionately by the shift to remote learning. By that summer, a group of 100 families filed suit against every school district and state department of education for failure to provide legally obligated services (Bond, Schoeneck, and King PLLC, 2020). Nearly a year later, several Republican U.S. House of Representatives committee leaders are requesting an investigation on the effects of school closures on SWD (Scalise et al., 2021). This Data Note explores teachers’ reports of how they are educating SWD during the COVID-19 pandemic using a nationally representative survey of more than 1,579 teachers in the RAND Corporation’s American Teacher Panel (ATP), which
