نویسندگان: خلاصه: 4 P. Asghari et al. 1 Introduction Eye tracking (ET) is frequently used, for example, in behavioral research and human-computer interaction. Eye movement patterns can reveal detailed infor- mation about the user’s cognitive processes, their attention level, or decision- making processes [3,12]. Applications and research based on ET require reliable and robust data [9]. Traditionally, this requires dedicated hardware with high- resolution cameras and infrared illumination to detect corneal reflections [7]. However, dedicated hardware is expensive and thus limits the pervasive use in real-world applications. This situation may change since, propelled by recent advances in deep learning, appearance-based gaze estimation methods that deliver promising results based on low-cost consumer-grade camera inputs start to emerge [2,10,11,21]. These approaches learn to estimate gazes from a video stream based on large-scale data sets and provide 3D gaze vectors or correspond- ing 2D gaze locations on a screen. Furthermore, they do not require any specific external devices and can be used with standalone computers, laptop built-in webcams, or mobile device consumer-grade cameras. This opens up the possi- bility of developing affordable automated intelligent ET solutions for research, commerce, and the general public. On the way to realize this ambition, webcam ET (wcET) has to address several challenges including gaze estimation accu- racy, gaze estimator prediction time, and that gaze estimation quality can be affected by user movements [11]. This paper aims to contribute to the first step toward utilizing wcET as a low-cost pervasive technology by validating the data quality of a state-of-the-art wcET approach in comparison to the performance of an established, commercially available dedicated eye tracking (dhET) system. Accordingly, we address the following research question in our work: How does the gaze estimates of wcET differ from dhET in practical settings regarding accu- racy, precision, and sampling rate? We will further discuss how the limitations of the data quality may affect the performance of wcET applications

Blockchain Technology and Emerging Technologies - Original PDF
نویسندگان: خلاصه: ID-Based Self-encryption via Hyperledger Fabric Based Smart Contract Ilya Grishkov1, Roland Kromes1(B), Thanassis Giannetsos2, and Kaitai Liang1 1 Cyber Security Group, Delft University of Technology, Delft, The Netherlands I.Grishkov-1@student.tudelft.nl, {R.G.Kromes,Kaitai.Liang}@tudelft.nl 2 Ubitech Ltd., Digital Security and Trusted Computing Group, Athens, Greece agiannetsos@ubitech.eu Abstract. This paper offers a prototype of a Hyperledger Fabric-IPFS based network architecture including a smart contract based encryp- tion scheme that meant to improve the security of user’s data that is being uploaded to the distributed ledger. A new extension to the self- encryption scheme was deployed by integrating data owner’s identity into the encryption process. Such integration allows to permanently pre- serve ownership of the original file and link it to the person/entity who originally uploaded it. Moreover, self-encryption provides strong security guarantees that decryption of a file is computationally not feasible under the condition that the encrypted file and the key are safely stored. Keywords: Blockchain · IPFS · Self-Encryption · Security · Hyperledger Fabric 1 Introduction The modern world is increasingly adopting blockchain technology. The first major market adoption of blockchain happened in 2009 when Bitcoin was introduced [12]. Interest in blockchain solutions grew over the years and lead to the invention of Ethereum - Bitcoin peer but with support for smart contracts which are digital codes enabling the description of complete business logic [1]. The introduction of smart contracts leads to further development in the field of blockchain and cre- ated demand for more industry-friendly solutions that allow to identify users of the system (Know-Your-Customer, Anti-Money-Laundering). Hyperledger Fab- ric was then introduced as a highly modular permissioned blockchain that allows great customization to suit particular industrial needs [3]. Given its customizabil- ity and modularity, Hyperledger Fabric (HLF) is a perfect platform for extending it with various trust and privacy preservation solutions

Bodily Subjects Essays on Gender and Health, 1800–2000 - PDF
نویسندگان: خلاصه: Constant good health is a chimera: the thing we all want, don’t notice when we have it, and mourn when we lose it. Being “healthy” is also something that women and men “do” in different ways. 1 The authors in Bodily Subjects all explore the historical entanglement between gender and health to expose how women and men “did” health in a variety of locations, from the nineteenth-century English Poor Law Union of Stourbridge, an early twentieth-century Aboriginal reserve in Queensland, Australia, to A I D S activists on the streets of Toronto in the 1990s. Our volume takes as its subject how gender is integral to the understanding of health and the way its meaning is embedded in cul- tural contexts connected to place and time. Our title reflects the way in which the body is both a subject of inquiry and a phenomenological experience. There is no “I” without a body and that body, Foucault has argued, is subject to regimes of power. 2 The title, Bodily Subjects, then, should be read in two ways. First, it re- fers to the embodied meanings of health for men and women and how these have expanded over time, from an able body signifying health in the nineteenth century to concepts of “well-being,” a psychological interpretation, which came to dominate health discourse in Western countries by the late twentieth century. Second, it refers to the way in which ill health turns individuals into subjects of the medical gaze. Medical expertise is brought to bear in diagnosing and treating indi- viduals in ways that are seen through the lens of gender
Construction Management JumpStart The Best First Step Toward a Career in Construction Management (3rd Edition) - Original PDF
نویسندگان: خلاصه: Introduction Congratulations! You are about to embark on an adventure. This book is about the processes, the people, and the practices that we call construction management—a term and a profession that may be unfamiliar to many people. Construction, as most individuals understand it, is an activity or a series of activities that involves some craftspeople, building materials, tools, and equip- ment. But you will learn that there is a great deal more to it than that. If you think that construction is all about brawn and not much about brains, then you probably haven’t been paying very close attention to what has been going on in the built environment in the past several decades. Buildings today can be very complicated, and the building process has become extremely demanding. It takes savvy professional talent to orchestrate all of the means and methods needed to accomplish the building challenge. This book’s focus is not on construction per se. Its focus is on the construction process and those individuals who manage that process. Construction manage- ment involves the organization, coordination, and strategic effort applied to the construction activities and the numerous resources needed to achieve the building objective. Construction management combines both the art and science of building technology along with the essential principles of business, management, computer technology, and leadership. Construction management as a profession is a relatively new concept, which may explain why you have not heard of it before. Up until the 1960s, the management tasks associated with large construction projects were typically handled by civil engineers. But in 1965, faculty from nine universities gathered in Florida to form the Associated Schools of Construction. What started as a movement to upgrade the status of construction education at universities evolved into a standardized construction management curriculum leading to an exciting new career choice, one for which there was increasing demand. Men and women who love the idea of transforming a lifeless set of plans and specifications into something real—a single-family home, a high-rise office building, a biotech facility, a super highway, or a magnificent suspension bridge—had found an educational program that provided both the academic course work and the practical management tools needed to plan, organize, and coordinate the increas- ingly complex construction process. If you are one of the many individuals who desire the intellectual challenges of architecture, engineering, technology, and business, yet long to be outside in the thick of things, getting your hands dirty and ultimately producing a tangible result—something of lasting value—then construction management might just be the ticket for you
Darwin: Portrait of a Genius by Paul Johnson - Epub + Converted PDF
نویسندگان: خلاصه: All his life, Charles Darwin believed that inheritance was much more important in shaping a man or woman than education or environment. Nature rather than nurture was formative, in his view. Though he knew nothing of the science of genetics, and never used the word gene, which is first recorded in English in 1911, more than a quarter- century after his death, he is a classic case of genetic inheritance. Indeed, two of his grandparents and his father can reasonably be classified as geniuses. His paternal grandfather, Erasmus Darwin (1731–1802) came from an old family of modest landowners. After Cambridge, he trained as a doctor in Edinburgh, and then practiced in Litchfield, Dr. Johnson’s town (they did not get on). He was successful and had many patients, easily earning £1,000 a year, a handsome income then. News of his skill reached the ears of George III, who invited him to come to London as the royal doctor. But Dr. Darwin declined. The Hanoverian royals were slow at paying their doctors. In any case, Darwin was happy as he was, combining a busy provincial practice with poetry and science. The symbol of this dualism was his coach, which he designed himself. It was fitted up with a writing desk, a skylight, and a portion of his library, so that he could carry on his intellectual pursuits while going on his daily round of professional calls.
Epistemology Modalized by Kelly Becker - Original PDF
نویسندگان: خلاصه: 1 Introduction: Externalism and modalism Recent developments in epistemology, and in philosophy more generally, provide a promising foundation for an answer to a very old question: What is knowledge? The question stymied Plato in the Theaetetus, from which the traditional tripartite analysis of knowledge as justified true belief derives. It received fresh attention when Edmund Gettier showed that the three conditions of the traditional analysis were not jointly sufficient for knowledge. Subsequent attempts to repair the analysis of knowledge aimed (1) to amend the notion of justification to avoid the Gettier problem; (2) to add a fourth condition, for instance that there are no defeaters to one’s justification; or (3) to replace justification with some other condition that captures the requisite link between belief and truth constitutive of knowledge. 1 The uniqueness of the third strategy is not clearly defined because one could easily argue that, whatever the necessary link between belief and truth turns out to be, it just is justification. Nonetheless, I see myself as pursuing this approach because the very term ‘‘justification’’ is all too pregnant with associated notions that I believe are not essential to knowledge, and work- ing toward an account that explicitly involves justification as a necessary condition can lead us away from a proper understanding of knowledge. (A specific instance of this problem arises in Chapter 2.) Unencumbered by the requirement to explicate ‘‘justification,’’ we can inquire into the requisite belief-truth link constitutive of knowledge by testing proposals for that link against our intuitions concerning whether an agent actually knows in parti- cular cases. If we find that a correct or, at least, working account of that link does not capture the traditional conception of justification, then so be it. 2 Our topic, then, is propositional knowledge: knowledge that p for some arbitrary proposition p. I will not claim that all other forms of knowledge, for instance, knowledge by acquaintance, knowledge of one’s own phenom- enological states, and know-how, are reducible to propositional knowledge, and so do not intend to give an account of knowledge in general. This only slightly diminishes the importance of an account of propositional knowl- edge, since it is through sentences and the propositions they express that we think and talk about the world. It would be a significant advance in our understanding if we had a plausible theory of such knowledge
Exporting the European Convention on Human Rights - Original PDF
نویسندگان: خلاصه: As for the right to protect one’s private and family life, as enshrined in Article 8 ECHR, the CJEU provided the very first explicit reference to the ECHR in Rutili v Minister for the Interior�53 In casu, the Convention was conceived as a source of inspiration as well as a human rights standard for determining the legality and legitimacy of the acts of Member States applying EU law. Therefore, the CJEU applied the ECHR as a clear human rights standard to also interpret the ‘public policy’ exception to the free movement of workers, justifying Member States to restrict this freedom only to the extent authorised by the ECHR, that is, when it is necessary for the protection of the interests of national security or public safety ‘in a democratic society’.54 This landmark case illustrates how the CJEU has progres- sively shaped its autonomous human rights case law, inspired, though, by the ECHR and by the common constitutional traditions of EU Member States.55 The Luxembourg Court established a much broader human rights review over their actions and paved the way for a much clearer reference to the Convention’s provi- sions as a material source of EU legal order, rather than a source of inspiration.56 Nonetheless, besides the consensus in this field, conflicts and inconsistencies between the two European jurisdictions have not been sidestepped. The main preoccupation of the following section is thus to unveil the extent to which the CJEU has directly referred to ECHR norms to protect private and family life57 with regard to the most controversial fields of data protection and migration/ asylum cases.
How to Become a Real Estate Agent in the Fastest Way Possible - Epub + Converted PDF
نویسندگان: خلاصه: How to Become a Real Estate Agent in the Fastest Way Possible Introduction In a world where passive income has become the order of the day, the real estate market offers a wide range of opportunities for you to gain that financial freedom and become your own boss. Several people entered the world of real estate from various occupations and stages of life. This may be due to the industry’s continual growth, creation of job opportunities, and provision of financial freedom. Compared to other types of investment, real estate ranks as one of the most stable, profitable, and least risky investments. Real estate is prominent because it offers variety. You don’t get to do the same thing every day. You get to work with clients and visit various homes in other locations. Plus, you get the satisfaction you get after helping out buyers and sellers. No matter the economic conditions, shelter is a necessity. People will always need a place to live or work, and this translates to the constant need for real estate. It never goes out of demand. However, you often hear ‘real estate market’ and think of flipping houses or renting houses to tenants. Although these fall under the real estate radar, there is so much more to it, and this book will provide insight into them. Being a real estate agent is a dream job. As all other jobs come with their own requirements and challenges, the real estate market also has its own challenges. However, with an extensive knowledge base, knowing the basic principles and strategies can make maneuvering the process much easier. Whether you are a newbie or an expert with years of experience in the art of real estate, this book will serve as a reliable guide for you.آیا کتاب مورد نظر هنوز بر روی سایت قرار نگرفته است؟ جای نگرانی نیست! کافی است بر روی گزینه سفارش کتاب کلیک کرده و درخواست خود را ثبت کنید. در کمتر از چند ساعت کتاب شما را آماده خواهیم کرد.
