    Adaptive Square-Shaped Trajectory-Based Service Location Protocol in Wireless Sensor Networks

    Get PDF
    In this paper we propose an adaptive square-shaped trajectory (ASST)-based service location method to ensure load scalability in wireless sensor networks. This first establishes a square-shaped trajectory over the nodes that surround a target point computed by the hash function and any user can access it, using the hash. Both the width and the size of the trajectory are dynamically adjustable, depending on the number of queries made to the service information on the trajectory. The number of sensor nodes on the trajectory varies in proportion to the changing trajectory shape, allowing high loads to be distributed around the hot spot area

    This paper presents concise comparison study of newly developed bioinspired algorithms for global optimization problems. Three different metaheuristic techniques, namely Accelerated Particle Swarm Optimization (APSO), Firefly Algorithm (FA), and Grey Wolf Optimizer (GWO) are investigated and implemented in Matlab environment. These methods are compared on four unimodal and multimodal nonlinear functions in order to find global optimum values. Computational results indicate that GWO outperforms other intelligent techniques, and that all aforementioned algorithms can be successfully used for optimization of continuous functions

    Experimental Evaluation of Growing and Pruning Hyper Basis Function Neural Networks Trained with Extended Information Filter

    In this paper we test Extended Information Filter (EIF) for sequential training of Hyper Basis Function Neural Networks with growing and pruning ability (HBF-GP). The HBF neuron allows different scaling of input dimensions to provide better generalization property when dealing with complex nonlinear problems in engineering practice. The main intuition behind HBF is in generalization of Gaussian type of neuron that applies Mahalanobis-like distance as a distance metrics between input training sample and prototype vector. We exploit concept of neuron’s significance and allow growing and pruning of HBF neurons during sequential learning process. From engineer’s perspective, EIF is attractive for training of neural networks because it allows a designer to have scarce initial knowledge of the system/problem. Extensive experimental study shows that HBF neural network trained with EIF achieves same prediction error and compactness of network topology when compared to EKF, but without the need to know initial state uncertainty, which is its main advantage over EKF

    D-STEM: a Design led approach to STEM innovation

    Get PDF
    Advances in the Science, Technology, Engineering and Maths (STEM) disciplines offer opportunities for designers to propose and make products with advanced, enhanced and engineered properties and functionalities. In turn, these advanced characteristics are becoming increasingly necessary as resources become ever more strained through 21st century demands, such as ageing populations, connected communities, depleting raw materials, waste management and energy supply. We need to make things that are smarter, make our lives easier, better and simpler. The products of tomorrow need to do more with less. It is recognised that STEM subjects need Design to translate and realise their full value to the economy and that Design’s role is greater than being a creator of objects. The issue is how to maximize the potential for exploiting opportunities offered by STEM developments and how best to enable designers to strengthen their position within the innovation ecosystem as active agents of change. As a society, we need designers able to navigate emerging developments from the STEM community to a level that enables understanding and knowledge of the new material properties, the skill set to facilitate absorption into the design ‘toolbox’ and the agility to identify, manage, contextualise and influence innovation opportunities emerging from STEM developments. This paper proposes the blueprint for a new design led approach to STEM innovation that begins to redefine studio culture for the 21st Century

    Knowledge and Management Models for Sustainable Growth

    In the last years sustainability has become a topic of global concern and a key issue in the strategic agenda of both business organizations and public authorities and organisations. Significant changes in business landscape, the emergence of new technology, including social media, the pressure of new social concerns, have called into question established conceptualizations of competitiveness, wealth creation and growth. New and unaddressed set of issues regarding how private and public organisations manage and invest their resources to create sustainable value have brought to light. In particular the increasing focus on environmental and social themes has suggested new dimensions to be taken into account in the value creation dynamics, both at organisations and communities level. For companies the need of integrating corporate social and environmental responsibility issues into strategy and daily business operations, pose profound challenges, which, in turn, involve numerous processes and complex decisions influenced by many stakeholders. Facing these challenges calls for the creation, use and exploitation of new knowledge as well as the development of proper management models, approaches and tools aimed to contribute to the development and realization of environmentally and socially sustainable business strategies and practices

    Handbook of Well-Being

    Get PDF
    It is a pleasure to bring to you the eHandbook of Subjective Well-Being, the science of when and why people experience and evaluate their lives in positive ways, including aspects such as positive feelings, life satisfaction, and optimism. There are chapters in this eHandbook on the philosophy and history of well-being, as well as reviews of empirical research on the ways to assess well-being, the circumstances that predict it, the outcomes that it produces, the societal policies that enhance it, and many other social, biological, and cultural processes that help us understand why some people are happy and satisfied with their lives, while others are not. There are also chapters on theories of well-being, such as the baseline or set-point models. We believe that Open publication is the wave of the future (Jhangiani & Biswas-Diener, 2017). Therefore, we are presenting the handbook in an electronic format so that it is widely available to everyone around the world. The handbook is entirely open and free – anyone can read and use it without cost. This is important to us as we desire to lower knowledge barriers for individuals and communities, especially because it provides access to students, educators, and scholars who do not have substantial financial resources. We are not certain if this is the first free and open handbook in the behavioral sciences, but hopefully it will not be the last. In the past the prohibitive price of many handbooks have made them available only to scholars or institutions in wealthy nations, and this is unfortunate. We believe scientific scholarship should be available to all. The field of subjective well-being has grown at rapid pace over the last several decades, and many discoveries have been made. When Ed Diener began his research within the field in 1981 there were about 130 studies published that year on the topic, as shown using a Google Scholar search on “subjective well-being.” Eighteen years later when Shigehiro Oishi earned his Ph.D. in 2000 there were 1,640 publications that year on the topic, and when Louis Tay was awarded a Ph.D. in 2011 there were 10,400 publications about subjective well-being. Finally, in 2016 there were 18,300 publications – in that single year alone! In other words, during the time that Diener has been studying the topic, scholarship on subjective well-being has grown over 100-fold! It is not merely the number of published studies that has grown, but there have been enormous leaps forward in our understanding. In the 1980s, there were questions about the reliability and validity of subjective well-being assessments, and the components that underlie it. One notable advance is our understanding and measurement of well-being. We now know a great deal about the validity of self-report measures, as well as the core evaluative and affective components that make up subjective well-being. Further, scholars have a much greater understanding of the processes by which people report their subjective well-being, and various biases or artifacts that may influence these reports. In 1982 many studies were focused on demographic factors such as income, sex, and age that were correlated with subjective well-being. By 2016 we understood much more about temperament and other internal factors that influence happiness, as well as some of the outcomes in behavior that subjective well-being helps produce (e.g., income, performance, physical health, longevity). In the 1980s, researchers assumed that people adapt to almost any life event, and that different life events only have a short-term effect on subjective well-being. A number of large-scale longitudinal studies later showed that that is not the case. By now we know what kinds of life events affect our subjective well-being, how much, and for roughly how long. In the 1980s researchers believed that economic growth would not increase the happiness of a given nation. Now we know when economic growth tends to increase the happiness of a given nation. Additionally, we know much more about the biology of subjective well-being, and an enormous amount more about culture and well-being, a field that was almost nonexistent in 1982. With the advent of positive psychology, we are also beginning to examine practices and interventions that can raise subjective well-being. Given the broad interest in subjective well-being in multiple fields like psychology, economics, political science, and sociology, there have been important developments made toward understanding how societies differ in well-being. This understanding led to the development of national accounts of well-being – societies using well-being measures to help inform policy deliberations. This advance changes the focus of governments away from a narrow emphasis on economic development to a broader view which sees government policies as designed to raise human well-being. We were fortunate to have so many leading scholars of subjective well-being and related topics contribute to this volume. We might be slightly biased but most of the chapters in this eHandbook are truly superb. Not only do they provide a broad coverage of a large number of areas, but many of the chapters present new ways of thinking about these areas. Below is a brief overview of each of the sections in this volume: In Section 1 we begin the volume with chapters on philosophical, historical, and religious thinking on well-being through the ages. Next, we cover the methods and measures used in the scientific study of well-being. Section 2 is devoted to theories of well-being such as the top-down theory, activity theory, goal theory, self-determination theory, and evolutionary theory. Section 3 covers the personality, genetics, hormones, and neuroscience of well-being. Then, demographic factors such as age, gender, race, religion, and marital status are discussed. Section 4 is devoted to how domains of life – such as work, finance, close relationships, and leisure – are related to overall subjective well-being. Section 5 covers the various outcomes of subjective well-being, ranging from work outcomes, to cognitive outcomes, to health, and finally relationship outcomes. Section 6 covers interventions to increase subjective well-being. Finally, Section 7 is devoted to cultural, geographical, and historical variations in subjective well-being. This eHandbook presents the most up-to-date and comprehensive understanding of subjective well-being – and it is freely available to all! The editors would like to extend their thanks to several individuals who have been critical to the success of the handbook. First, our gratitude is immense toward Chris Wiese, Keya Biswas-Diener, and Danielle Geerling, who organized and kept the entire venture on track. Their hard work and organizational skills were wonderful, and the book would not have been possible without them. Second, we extend our thanks to the Diener Education Fund, a charitable organization devoted to education that in part made this project possible. In particular we express deep gratitude to Mary Alice and Frank Diener. Not only did their help make this eHandbook possible, but their lives stood as shining examples of the way to pursue well-being!https://digitalcommons.unomaha.edu/psychfacbooks/1008/thumbnail.jp
