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
AN INTRODUCTION TO PERFORMANCE ANALYSIS OF SPORT - Original PDF
نویسندگان: خلاصه: This introductory chapter introduces sports performance analysis by asking the following questions: What? Why? Who? Where? When? and How? What is sports performance analysis? What are sports performance data and information? Why do we analyse sports performance? Who analyses sports performance? Where is sports performance analysis done? When is sports performance analysis done? How is sports perform- ance analysis done? The answers to these questions are not independent. The reason why sports performance analysis is done and who requires the information can dictate what information is required. The informa- tion required can in turn influence when it is needed and thus when sports performances should be analysed. The time at which information is needed and economic constraints dictate the methods and locations of sports performance analysis tasks. These questions will be answered in turn but readers can expect some necessary overlap between the answers.
Comminution 1994 Proceedings of the 8th European Symposium on Comminution and 50th Event of the European Federation of Chemical Engineering, May 17-19, 1994 Stockholm, Swede - PDF
نویسندگان: خلاصه: Particle arrangements and confinements can be classified in the four groups (1) single particle situation, (2) one-particle layer, (3) particle bed confined closely or widely, and (4) ideal particle bed. Any confinement influences the stress distribution inside the bed due to the wall friction, and a complex stress field arises. The size-reduction effect is represented with the fraction of broken particles, the breakage function and the specific surface increases. The breakage functions of the particle bed comminution display as truncated logarithmic normal distributions. The stressing intensity can be quantified by the pressure, the stress field characteristics or the energy absorption. Although the stress field situation can differ extremely, the overall energy absorption has been proven to represent the stressing intensity very well in respect to the size-reduction. The transition from a close to a moderately wide confinement does not affect the size-reduction strongly. Steel balls inserted in a particle bed improve the breakage of coarse particles at a low intensity level. This advantage fades with increasing intensity and decreasing particle size.
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
Game storming by Dave Gray Sunni Brown James Macanufo - Epub + Converted PDF
نویسندگان: خلاصه: Imagine a boy playing with a ball. He kicks the ball against a wall, and the ball bounces back to him. He stops the ball with his foot and kicks it again. By engaging in this kind of play, the boy learns to associate certain movements of his body with the movements of the ball in space. We could call this associative play. Now imagine that the boy is waiting for a friend. The friend appears, and the two boys begin to walk down a sidewalk together, kicking the ball back and forth as they go. Now the play has gained a social dimension; one boy's actions suggest a response, and vice versa. You could think of this form of play as a kind of improvised conversation, where the two boys engage each other using the ball as a medium. This kind of play has no clear beginning or end; rather, it flows seamlessly from one state into another. We could call this streaming play. Now imagine that the boys come to a small park, and that they become bored simply kicking the ball back and forth. One boy says to the other, "Let's take turns trying to hit that tree. You have to kick the ball from behind this line." The boy draws a line by dragging his heel through the dirt. "We'll take turns kicking the ball. Each time you hit the tree you get a point. First one to five wins." The other boy agrees and they begin to play. Now the play has become a game; a fundamentally different kind of play. What makes a game different? We can break down this very simple game into some basic components that separate it from other kinds of play.Imagine a boy playing with a ball.

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.
Arvid Schors Doppelter Boden. Die SALT-Verhandlungen 1963-1979 - Original PDF
نویسندگان: خلاصه: Initiativen zur Reduzierung der nuklearen Bedrohung hatte es seit Be- ginn des Kalten Krieges immer wieder gegeben. Die USA hatten bereits 1946 unter dem Eindruck der Atombombenabwürfe über Hiroshima und Nagasaki den Baruch-Plan vorgelegt. Er sah die Errichtung einer internationalen Körperschaft vor, der ein globales Monopol für die militärische Nutzung der Atomkraft zukommen sollte. Dieses Konzept einer vollständigen nuklearen Abrüstung scheiterte am Widerstand der Sowjetunion, die zu diesem Zeitpunkt den USA nukleartechnisch unter- legen und deshalb nicht bereit war, eine Vereinbarung zu schließen, die das US -amerikanische Atomwaffenmonopol auf Jahre hin festgeschrie- ben hätte.1 Mit ihrem ersten erfolgreichen Atomwaffentest brach die Sowjetunion 1949 schließlich dieses amerikanische Monopol.2 Während der 1950er Jahre begann auch sie stärkeres Gewicht auf Atomwaffen und ballistische Raketen zu legen
Handbook of Research on Promoting Higher- Order Skills and Global Competencies in Life and Work - Original PDF
نویسندگان: خلاصه: ABSTRACT Critical thinking and other higher-order thinking skills are key objectives of higher education. Through the development of higher-order thinking skills, students are able to discern information from multiple, often competing sources, make sound judgements, draw conclusions, and enact creative solutions to complex problems. However, faculty can struggle with how to help students develop higher-order think- ing skills, relying instead on transmission of knowledge, focusing on what to learn instead of how to learn. In this chapter, the author provides insights into the connections between using gamification as a pedagogical approach, and the development of higher-order thinking skills. The chapter addresses perspectives on higher-ordering thinking, approaches to gamification in college courses, and concludes with recommendations for faculty in approaching gamificationآیا 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.
