Download or read book Quantum Communications and Cryptography written by Alexander V. Sergienko and published by CRC Press. This book was released on 2018-10-03 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: All current methods of secure communication such as public-key cryptography can eventually be broken by faster computing. At the interface of physics and computer science lies a powerful solution for secure communications: quantum cryptography. Because eavesdropping changes the physical nature of the information, users in a quantum exchange can easily detect eavesdroppers. This allows for totally secure random key distribution, a central requirement for use of the one-time pad. Since the one-time pad is theoretically proven to be undecipherable, quantum cryptography is the key to perfect secrecy. Quantum Communications and Cryptography is the first comprehensive review of the past, present, and potential developments in this dynamic field. Leading expert contributors from around the world discuss the scientific foundations, experimental and theoretical developments, and cutting-edge technical and engineering advances in quantum communications and cryptography. The book describes the engineering principles and practical implementations in a real-world metropolitan network as well as physical principles and experimental results of such technologies as entanglement swapping and quantum teleportation. It also offers the first detailed treatment of quantum information processing with continuous variables. Technologies include both free-space and fiber-based communications systems along with the necessary protocols and information processing approaches. Bridging the gap between physics and engineering, Quantum Communications and Cryptography supplies a springboard for further developments and breakthroughs in this rapidly growing area.

Download or read book Confronting Poverty in Iraq written by World Bank and published by World Bank Publications. This book was released on 2011-01-10 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report provides the most comprehensive and rigorous analysis of Iraqi income and expenditure in several decades. The report makes extensive use of the Iraq Household Socio-Economic Survey, the first nationwide income and expenditure survey since 1988. IHSES data is complemented income and expenditure data from a wide range of other measures of living standards, allowing us to analyze living standards in a holistic way. The analysis presented here was performed with two main goals first, to inform the Government s Poverty Reduction Strategy; and second, to serve as a baseline for future assessments of changes in living standards and the identification of critical issues for deeper examination. Iraqi living standards have two unusual characteristics. First, they have fallen over the past generation. Second, they feature surprisingly little inequality. These characteristics are both rooted in Iraq s recent history of authoritarian government, war, military occupation, insurgency, and civil strife leading to infrastructure destruction and population displacement. There have been few opportunities for individuals to prosper from professional or entrepreneurial activities. Decades of neglected investment have resulted in deterioration of social services and economic infrastructure. Consequently, individuals have lacked capabilities to prosper and an investment climate conducive to prosperity. School enrollment and life expectancy have declined. Extremely low returns to education reflect the combination of poor educational quality and lack of employment opportunities. In terms of economic infrastructure, access to reliable electricity and water, and even access to paved roads are low, are further reflections of decades of neglect. While the upper end of the distribution has been pulled down by a lack of opportunities, the lower end has been supported by direct government provision of food. The Public Distribution System (PDS) provides 85 percent of food needs. While PDS has been useful as a safety net for the poor and the vulnerable, the system is expensive, inefficient, and fiscally risky. Indeed, PDS food rations account for a far greater share of public spending than does education or health. Going forward, Iraq faces two main challenges. First, although Iraq does not have to develop from scratch, it faces a formidable challenge in re-development. Second, a shift by the Government is required from direct provision of basic subsistence toward investment in human capacities. The Government can provide an enabling environment through investments in economic infrastructure and services to business and citizens, thus allowing the population to make productive use of education and their own labor. Both challenges are now being taken up by the Poverty Reduction Strategy, which articulates a detailed set of required actions and outlines priorities for government spending.

Download or read book Conceptual Modeling for Traditional and Spatio Temporal Applications written by Christine Parent and published by Springer Science & Business Media. This book was released on 2006-09-02 with total page 475 pages. Available in PDF, EPUB and Kindle. Book excerpt: From environmental management to land planning and geo-marketing, the number of application domains that may greatly benefit from using data enriched with spatio-temporal features is expanding very rapidly. This book shows that a conceptual design approach for spatio-temporal databases is both feasible and easy to apprehend. While providing a firm basis through extensive discussion of traditional data modeling concepts, the major focus of the book is on modeling spatial and temporal information.

Download or read book Reset Your Child s Brain written by Victoria L. Dunckley, MD and published by New World Library. This book was released on 2015-06-23 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: Increasing numbers of parents grapple with children who are acting out without obvious reason. Revved up and irritable, many of these children are diagnosed with ADHD, bipolar illness, autism, or other disorders but don’t respond well to treatment. They are then medicated, often with poor results and unwanted side effects. Based on emerging scientific research and extensive clinical experience, integrative child psychiatrist Dr. Victoria Dunckley has pioneered a four-week program to treat the frequent underlying cause, Electronic Screen Syndrome (ESS). Dr. Dunckley has found that everyday use of interactive screen devices — such as computers, video games, smartphones, and tablets — can easily overstimulate a child’s nervous system, triggering a variety of stubborn symptoms. In contrast, she’s discovered that a strict, extended electronic fast single-handedly improves mood, focus, sleep, and behavior, regardless of the child’s diagnosis. It also reduces the need for medication and renders other treatments more effective. Offered now in this book, this simple intervention can produce a life-changing shift in brain function and help your child get back on track — all without cost or medication. While no one in today’s connected world can completely shun electronic stimuli, Dr. Dunckley provides hope for parents who feel that their child has been misdiagnosed or inappropriately medicated, by presenting an alternative explanation for their child’s difficulties and a concrete plan for treating them.

Download or read book The Revolt of The Public and the Crisis of Authority in the New Millennium written by Martin Gurri and published by Stripe Press. This book was released on 2018-12-04 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: How insurgencies—enabled by digital devices and a vast information sphere—have mobilized millions of ordinary people around the world. In the words of economist and scholar Arnold Kling, Martin Gurri saw it coming. Technology has categorically reversed the information balance of power between the public and the elites who manage the great hierarchical institutions of the industrial age: government, political parties, the media. The Revolt of the Public tells the story of how insurgencies, enabled by digital devices and a vast information sphere, have mobilized millions of ordinary people around the world. Originally published in 2014, The Revolt of the Public is now available in an updated edition, which includes an extensive analysis of Donald Trump’s improbable rise to the presidency and the electoral triumphs of Brexit. The book concludes with a speculative look forward, pondering whether the current elite class can bring about a reformation of the democratic process and whether new organizing principles, adapted to a digital world, can arise out of the present political turbulence.
