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

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
Housing Policy in the United States Fourth Editio - Original PDF
نویسندگان: خلاصه: 1 Introduction In its preamble to the 1949 Housing Act, Congress declared its goal of “a decent home in a suit- able living environment for every American family.” In the more than 60 years since this legisla- tion was passed, the federal government has helped fund the construction and rehabilitation of more than 5 million housing units for low-income households and provided rental vouchers to nearly 2 million additional families. Yet, the nation’s housing problems remain acute. In 2017, 44.7 million households lived in physically deficient housing, spent 30 percent or more of their income on housing, or were homeless (U.S. Census Bureau 2018; U.S. Department of Housing and Urban Development 2018). Put differently, about 113 million Americans—around 35 per- cent of the nation’s population and more than triple the 28.5 million lacking health insurance in 2017 (Berchick, Hood, & Barnett 2018)—confronted serious housing problems or had no housing at all.1 This book tells the story of how the United States has tried to address the nation’s housing problems. It looks at the primary policies and programs designed to make decent and affordable housing available to Americans of modest means. It examines the strengths and weaknesses of these policies and programs and the challenges that still remain. The book takes a broad view of housing policy, focusing not only on specific housing subsidy programs, such as public housing, but also on the federal income tax code and regulations affecting mortgage lending, land use decisions, real estate transactions, and other activities integral to the housing market. Some of these broader aspects of housing policy provide financial incentives for investments in affordable housing, others attempt to make housing available to low-income and minority households and communities by penalizing discriminatory practices and through other regulatory interventions. Put simply, then, this book is about policies and programs designed to help low-income and other disadvantaged individuals and households access decent and affordable housing. It examines programs and policies that subsidize housing for low-income households or that attempt to break down institutional barriers, such as discriminatory practices in the real estate industry that impede access to housing. The book is intended to be a general overview of housing policy. It is beyond its scope to delve deeply into programmatic details or to cover all aspects of the field in equal depth. The focus is on federal and, to a lesser degree, state and local programs and policies that subsidize housing for low-income households or otherwise attempt to make housing accessible to this population. Much less attention is given to policies concerned with the physical aspects of housing, such as design standards and building regulations—except when they are explicitly employed to promote affordable housing. The book does not examine in detail the operation of housing markets or pro- vide a comprehensive legislative history of housing policy.
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.
