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

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.
Assistive Technologies and Environmental Interventions in Healthcare - Original PDF
نویسندگان: خلاصه: The changes we have all seen in technology and corre spondingly with assistive technology in the past 10 years are mind‐boggling. Futurist and inventor Ray Kurzweil (2000) stated early in the twenty‐first century that com puters are 100 million times more powerful than they were 50 years ago. The exponential growth of computer capacity that Kurzweil and others predicted in the late 1990s continues to advance and has the potential for improving all aspects of life (Diamandis and Kotler 2014). These exponential changes in technology make it hard to keep up with the latest innovations. For example, one of the chapter authors worked in an assistive technology laboratory in which serial port add‐ons to computers evolved into Universal Serial Bus (USB) ports rendering the former connections and their attachments obsolete within in less than five years. Currently, com puters no longer come with disk drives and all of the software one needs to load on the computer comes from the cloud. Vicente (2006) stated, “... more and more technology is being foisted upon us at a faster and faster pace” (p. 13). In addition, technology is clearly a necessary part of our lives. For many of us, it is difficult to remember a time when cell phones, laptops, or navigation devices were not available to those who could afford it. Furthermore, the convergence of multiple technologies into a single, small, handheld device such as a smart phone is common as part of our work and personal experiences
Discrete Element Modelling of Particulate Media by Chuan-Yu Wu - Original PDF
نویسندگان: خلاصه: In numerical simulations of dense two-phase flow involving particulate materials the Discrete Element Method (DEM) has proved particularly effective in capturing the complex hydrodynamics of the solid phase. 1 DEM-based granular solid dynamics, including collisions and persistent contact with elaborate force-displacement laws, friction and cohesion have shown to be superior to traditional fluid-like, continuum approaches, which typically require coarse approximations and the introduction of artificial variables like solids pressure and viscosity. However, computational limitations of DEM models do not allow adding also the burden of flow simulations resolved at the level of particle-particle interstices, so that typically an averaged scale approach, with computational cell sizes of the order of a few particle diameters, is used. 2 .3 As a consequence, formulations of the drag force acting on individual particles are required to close the set of equations to solve for the solid and fluid phases. While many drag force models for monodisperse systems have been proposed in the literature, as discussed below, expressions for such force on a particle in a multi-particle system is currently the subject of extensive research work
Ecologies of Socialisms - Original PDF
نویسندگان: خلاصه: Eli Rubin and Scott Moranda Introduction Is Germany the “Greenest nation” as Frank Uekötter has provocatively asked?1 Forget the Berlin Wall, forget the Cold War, World War II, the Nazis, the Holocaust, the Kaiserreich, and forget the storied history of the Social Democratic Party – the SPD. Germany is now the nation of separated trash, solar panels and wind power. The only Wende people talk about now, in relation to Germany, is the Energiewende. And perhaps, that is part of the point. The Energiewende provides for a national identity that generates warm, positive press and seemingly avoids the more divisive and troubling aspects of past markers of Germanness. Even if the reality of the “greenest nation” is more complicated, it is undeniable that Germany has been at the center of the global history of environmentalism. Scientific conservation had deep roots among the forest- ers, urban planners, and other technical experts of Wilhelmine Germany who had outsized influence on Progressive reformers in the United States and British civil servants across their Empire.2 German-speakers also shaped Romanticism, ecology, and notions of holistic interconnectedness, most importantly in the figure of Alexander von Humboldt, whose Kosmos had a global influence.
Evolution 2.0: Breaking the Deadlock Between Darwin and Design - Epub + Converted PDF
نویسندگان: خلاصه: This product is estimated to be delivered within 2-3 weeks from the dispatch date. In the ongoing debate about evolution, science and faith face off. But the truth is both sides are right and wrong. In one corner: Atheists like Richard Dawkins, Daniel Dennett, and Jerry Coyne. They insist evolution happens by blind random accident. Their devout adherence to Neo-Darwinism omits the latest science, glossing over crucial questions and fascinating details. In the other corner: Intelligent Design advocates like William Dembski, Stephen Meyer, and Michael Behe. Many defy scientific consensus, maintaining that evolution is a fraud and rejecting common ancestry outright. There is a third way. Evolution 2.0 proves that, while evolution is not a hoax, neither is it random nor accidental. Changes are targeted, adaptive, and aware. You’ll discover: How organisms re-engineer their genetic destiny in real time Amazing systems living things use to re-design themselves Every cell is armed with machinery for editing its own DNA The five amazing tools organisms use to alter their genetics 70 years of scientific discoveries-of which the public has heard virtually nothing! Perry Marshall approached evolution with skepticism for religious reasons. As an engineer, he rejected the concept of organisms randomly evolving. But an epiphany-that DNA is code, much like data in our digital age-sparked a 10-year journey of in-depth research into more than 70 years of under-reported evolutionary science. This led to a new understanding of evolution-an evolution 2.0 that not only furthers technology and medicine, but fuels our sense of wonder at life itself. This book will open your eyes and transform your thinking about evolution and God. You’ll gain a deeper appreciation for our place in the universe. You’ll see the world around you as you’ve never seen it before. Evolution 2.0 pinpoints the central mystery of biology, offering a multimillion dollar technology prize at naturalcode.org to the first person who can solve it.
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.

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.
