Скачать книгу - The Sparse Fourier Transform



The Fourier transform is one of the most fundamental tools for computing the frequency representation of signals. It plays a central role in signal processing, communications, audio and video compression, medical imaging, genomics, astronomy, as well as many other areas. Because of its widespread use, fast algorithms for computing the Fourier transform can benefit a large number of applications. The fastest algorithm for computing the Fourier transform is the Fast Fourier Transform (FFT), which runs in near-linear time making it an indispensable tool for many applications. However, today, the runtime of the FFT algorithm is no longer fast enough especially for big data problems where each dataset can be few terabytes. Hence, faster algorithms that run in sublinear time, i.e., do not even sample all the data points, have become necessary. This book addresses the above problem by developing the Sparse Fourier Transform algorithms and building practical systems that use these algorithms to solve key problems in six different applications: wireless networks; mobile systems; computer graphics; medical imaging; biochemistry; and digital circuits. This is a revised version of the thesis that won the 2016 ACM Doctoral Dissertation Award.

In TRANSFORMATA (Cartea 1 din Memoriile unui vampir), Caitlin Paine, de 18 ani, se treze?te scoasa cu for?a din frumoasa ei suburbie ?i for?ata sa urmeze un periculos liceu din ora?ul New York, cand mama ei se muta din nou. Singura raza de lumina in noile ei imprejurimi este Jonah, un nou coleg care o place la prima vedere. Dar, inainte ca iubirea lor sa poata inflori, Caitlin descopera dintr-o data ca se schimba. Ea este cople?ita de o putere supraomeneasca, o sensibilitate la lumina, o dorin?a de a se hrani – de sentimente pe care nu le in?elege. Ea cauta raspunsuri la ceea ce i se intampla, ?i poftele ei o duc la locul nepotrivit, la momentul nepotrivit. Ochii ei se deschid catre o lume ascunsa, chiar sub picioarele ei, inflorind in subteranele ora?ului New York. Ea se treze?te prinsa intre doua sabaturi periculoase, chiar in mijlocul unui razboi intre vampiri. Acesta este momentul cand Caitlin il intalne?te pe Caleb, un vampir misterios ?i puternic care o salveaza de for?ele intunericului. El are nevoie de ajutorul ei, are nevoie ca ea sa-l conduca la legendarul artefact pierdut. ?i ea are nevoie de el pentru raspunsuri ?i pentru protec?ie. Impreuna, ei vor trebui sa raspunda la o intrebare cruciala: cine a fost tatal ei adevarat? Dar Caitlin se treze?te prinsa intre doi barba?i, caci ?i altceva apare intre ei: o dragoste interzisa. O dragoste intre rase care le va risca vie?ile amandurora, si ii va forta sa decida daca sa ri?te totul unul pentru altul…

The modern business climate demands a new risk management strategy Mastering Strategic Risk: A Framework for Leading and Transforming Organizations is a comprehensive guide to redesigning organizational systems to better manage the risks and complexities of the modern world. Based on the notion of «Create, Facilitate, and Support,» the book provides a roadmap to ensuring optimum performance in even the most challenging circumstances. Whether applied to a system or an entire organization, the ideas presented can help unlock a business's potential and ensure a sustainable advantage. Modern business leaders face unprecedented challenges, and risk management has become a strategic priority. Traditional management frameworks are outdated, and cannot be re-tooled to effectively account for the demands and complexities of the 21st century. Instead of adjusting old, ineffective models, businesses are better served by implementing an entirely new model custom-built to lead organizations through today's business environment. Mastering Strategic Risk describes this brand new framework, and provides the tools and background leaders need to remain effective in this new age. Topics include: The three forces behind customer behavior, competitive advantage, and a culture of discipline New major change agents that drive complexity and intensity Tools that help identify and mitigate the biggest risks to operations A new HR model to drive peak performance and galvanize employees The book contains well-known real-world examples from Wachovia, Toyota, World-Com, and Citrix, that illustrate key concepts within the new framework and demonstrate the core elements of modern risk management. For the savvy leader looking to push an organization to the next level, Mastering Strategic Risk: A Framework for Leading and Transforming Organizations provides a brand new model for effective management.
