    Machine learning in solar physics

    Full text link
    The application of machine learning in solar physics has the potential to greatly enhance our understanding of the complex processes that take place in the atmosphere of the Sun. By using techniques such as deep learning, we are now in the position to analyze large amounts of data from solar observations and identify patterns and trends that may not have been apparent using traditional methods. This can help us improve our understanding of explosive events like solar flares, which can have a strong effect on the Earth environment. Predicting hazardous events on Earth becomes crucial for our technological society. Machine learning can also improve our understanding of the inner workings of the sun itself by allowing us to go deeper into the data and to propose more complex models to explain them. Additionally, the use of machine learning can help to automate the analysis of solar data, reducing the need for manual labor and increasing the efficiency of research in this field.Comment: 100 pages, 13 figures, 286 references, accepted for publication as a Living Review in Solar Physics (LRSP

    Eating Behavior In-The-Wild and Its Relationship to Mental Well-Being

    Get PDF
    The motivation for eating is beyond survival. Eating serves as means for socializing, exploring cultures, etc. Computing researchers have developed various eating detection technologies that can leverage passive sensors available on smart devices to automatically infer when and, to some extent, what an individual is eating. However, despite their significance in eating literature, crucial contextual information such as meal company, type of food, location of meals, the motivation of eating episodes, the timing of meals, etc., are difficult to detect through passive means. More importantly, the applications of currently developed automated eating detection systems are limited. My dissertation addresses several of these challenges by combining the strengths of passive sensing technologies and EMAs (Ecological Momentary Assessment). EMAs are a widely adopted tool used across a variety of disciplines that can gather in-situ information about individual experiences. In my dissertation, I demonstrate the relationship between various eating contexts and the mental well-being of college students and information workers through naturalistic studies. The contributions of my dissertation are four-fold. First, I develop a real-time meal detection system that can detect meal-level episodes and trigger EMAs to gather contextual data about one’s eating episode. Second, I deploy this system in a college student population to understand their eating behavior during day-to-day life and investigate the relationship of these eating behaviors with various mental well-being outcomes. Third, based on the limitations of passive sensing systems to detect short and sporadic chewing episodes present in snacking, I develop a snacking detection system and operationalize the definition of snacking in this thesis. Finally, I investigate the causal relationship between stress levels experienced by remote information workers during their workdays and its effect on lunchtime. This dissertation situates the findings in an interdisciplinary context, including ubiquitous computing, psychology, and nutrition.Ph.D

    A survey on artificial intelligence-based acoustic source identification

    Get PDF
    The concept of Acoustic Source Identification (ASI), which refers to the process of identifying noise sources has attracted increasing attention in recent years. The ASI technology can be used for surveillance, monitoring, and maintenance applications in a wide range of sectors, such as defence, manufacturing, healthcare, and agriculture. Acoustic signature analysis and pattern recognition remain the core technologies for noise source identification. Manual identification of acoustic signatures, however, has become increasingly challenging as dataset sizes grow. As a result, the use of Artificial Intelligence (AI) techniques for identifying noise sources has become increasingly relevant and useful. In this paper, we provide a comprehensive review of AI-based acoustic source identification techniques. We analyze the strengths and weaknesses of AI-based ASI processes and associated methods proposed by researchers in the literature. Additionally, we did a detailed survey of ASI applications in machinery, underwater applications, environment/event source recognition, healthcare, and other fields. We also highlight relevant research directions

    Coworking through the Pandemic: Flexibly Yours

    Get PDF
    Coworking can be defined as a paid for service (usually) providing shared workspace and amenities to users. When the pandemic hit, owing to the business model’s in-person foundations of physical proximity and shared amenities, the coworking industry was expected to be seriously impacted. Yet fast forward, and as the pandemic has played out, coworking businesses are uniquely positioned in this uncertain and changing workscape. This dissertation presents one of the first academic explorations into how independent coworking businesses fared in the initial year of the pandemic. Specifically, the research explores the following questions: 1. How did independent coworking businesses manage and adapt to the pandemic? 2. What is virtual coworking and what are the experiences of workers in these virtual coworking spaces? 3. How does coworking flexibility affect social support and connection? Using a critically interpretive poststructural approach, this ethnography included virtual fieldwork and interviews. Sixty hours of virtual participant observation and 30 loosely structured interviews were conducted with coworking stakeholders (i.e., owner-operators, managers, and users) over videoconferencing platforms. Secondary data included written fieldnotes and coworking documents. Results capture the strategies used by coworking business owner-operators and managers to sustain their businesses and the attendant relationships with coworking users, irrespective of whether or not a physical location could be provided under pandemic lockdowns. Given the expansion of coworking businesses into virtual service offerings, a key contribution of my research is the finding that co-location in a physical coworking space is not necessary to cultivate vibes and a sense of community. By removing the physical infrastructure of coworking, the virtual coworking product in which I participated points to both a reinforcement of and an emphasis on the centrality of social connection, support, and community. By de-centering the priority of a physical co-location, I conceptualize coworking businesses as commodified support infrastructures—affective atmospheres produced through the entanglement of human bodies, other living things, objects, and technologies in a space. In viewing coworking businesses as fluid affective atmospheres of support, my research adds to the emerging coworking scholarship that attends to the atmospheric qualities of coworking, the role of affective labour, and the possibilities of encounters and interactions as bodies, objects, and technologies interconnect. My results reinforce the deep ambivalence of coworking, capturing tensions between productivity and sociality, and a blurring of boundaries between professional and private, and work and leisure. The analysis also suggests that the inherent flexibility, informality, turnover, and autonomy in coworking practices can make creating stable social connections and support difficult. Finally, the COVID-19 crisis brought to light how coworking lies primarily outside the scope of current employment legislation, which includes occupational health and safety, employment standards, and workers’ compensation. In the absence of well-defined policy directions, coworking business owner-operators and managers made individualized decisions, thereby ultimately downloading further risk and responsibility onto their coworking users

    The nexus between e-marketing, e-service quality, e-satisfaction and e-loyalty: a cross-sectional study within the context of online SMEs in Ghana

    Get PDF
    The spread of the Internet, the proliferation of mobile devices, and the onset of the COVID-19 pandemic have given impetus to online shopping in Ghana and the subregion. This situation has also created opportunities for SMEs to take advantage of online marketing technologies. However, there is a dearth of studies on the link between e-marketing and e-loyalty in terms of online shopping, thereby creating a policy gap on the prospects for business success for online SMEs in Ghana. Therefore, the purpose of the study was to examine the relationship between the main independent variable, e-marketing and the main dependent variable, e-loyalty, as well as the mediating roles of e-service quality and e-satisfaction in the link between e-marketing and e-loyalty. The study adopted a positivist stance with a quantitative method. The study was cross-sectional in nature with the adoption of a descriptive correlational design. A Structural Equation Modelling approach was employed to examine the nature of the associations between the independent, mediating and dependent variables. A sensitivity analysis was also conducted to control for the potential confounding effects of the demographic factors. A sample size of 1,293 residents in Accra, Ghana, who had previously shopped online, responded to structured questionnaire in an online survey via Google Docs. The IBM SPSS Amos 24 software was used to analyse the data collected. Positive associations were found between the key constructs in the study: e-marketing, e-service quality, e-satisfaction and e-Loyalty. The findings from the study gave further backing to the diffusion innovation theory, resource-based view theory, and technology acceptance model. In addition, e-service quality and e-satisfaction individually and jointly mediated the relationship between e-marketing and e-loyalty. However, these mediations were partial, instead of an originally anticipated full mediation. In terms of value and contribution, this is the first study in a developing economy context to undertake a holistic examination of the key marketing performance variables within an online shopping context. The study uniquely tested the mediation roles of both e-service quality and e-satisfaction in the link between e-marketing and e-loyalty. The findings of the study are novel in the e-marketing literature as they unearthed the key antecedents of e-loyalty for online SMEs in a developing economy context. The study suggested areas for further related studies and also highlighted the limitations
