Book Description
Nowadays, most digital modulation schemes are based on conventional signal constellations that have no algebraic group, ring, or field properties, e.g. square quadrature-amplitude modulation constellations. Signal constellations with algebraic structure can enhance the system performance. For instance, multidimensional signal constellations based on dense lattices can achieve performance gains due to the dense packing. The algebraic structure enables low-complexity decoding and detection schemes. In this work, signal constellations with algebraic properties and their application in spatial modulation transmission schemes are investigated. Several design approaches of two- and four-dimensional signal constellations based on Gaussian, Eisenstein, and Hurwitz integers are shown. Detection algorithms with reduced complexity are proposed. It is shown, that the proposed Eisenstein and Hurwitz constellations combined with the proposed suboptimal detection can outperform conventional two-dimensional constellations with ML detection.

Book Description
Sharing information and knowledge, co-innovating with clients, communities, and competitors and adopting cognitive technology, robo advisors, crowdfunding, and blockchain reflect current socio-economic behaviour. Emerging growth regions in Asia, demographic shifts, intergenerational wealth transfers and increasing regulations are other trends that amplify each other, disrupt the client journey, and affect the entire economy. Moreover, unprecedentedly, new market entrants outside the financial sector, be it Amazon, Apple, Google, or Facebook, are increasingly expanding their scale and scope to offer financial services. Featuring case studies of Chinese business ecosystems, such as Alibaba/Ant Financial, that have transformed from displaying domestic and organic growth to rapid global expansion, this highly readable book gives you glimpses of how banking services are evolving. We break down everything you need to know about the foray of challenger banks into the financial services. You learn how they link health to wealth data and gain advantages through analytical capabilities in the race to attract sophisticated clients with highly personalized experiences. The next level of creating and capturing value for clients and businesses involves platform models embedded in cross-sector ecosystems. Digital platforms are the crucial entry point to global markets, creating value for multiple sides. They leverage self-driving ecosystems that go beyond linear value chains applied in traditional business models as the sources of growth in an interconnected world are collaboration and network effects. The winners will be those who open up and engage themselves in an ecosystem that transcends organizational boundaries and performs without sector borders because every actor contributes to the value constellation of the system. The book provides practitioners and scholars with new insights into open and holistic business models, where competition in future will be between ecosystems rather than at the company level. It encourages leaders to expand their skills and think through the lens of the ecosystem theory while developing compelling strategies to serve the next-generation clients.

Book Description
A modern-day love story that explores childhood trauma, the boundaries between idealism and self-righteousness, and the heartaches we must confront in order to chart our courses forward. Lo Gunderson feels trapped in her small midwestern hometown until she sees an ad for a free car in the local paper. To maintain her staunch anticapitalist values, she refuses to spend money on what she can find for free, so this car is the perfect ticket out of the town. Though it doesn’t cost any money, it still comes with a price. Blanche Peterson is dying and asks for a single favor—that Lo track down her estranged son, whom Blanche hasn’t seen in over a decade. Before she can decide whether to fulfill Blanche’s dying wish, she needs to get the car started. She’s helped by John Blank, a Southern auto mechanic who moved up north for a fresh start. Despite vastly different backgrounds, they share an electrifying mutual attraction that threatens to upend Lo’s carefully constructed worldview. Meanwhile, Blanche’s son, Jason, finds himself adrift after an argument with his girlfriend. Memories of his negligent mother and the death of his father resurface for the first time in years as he travels across the country searching for what comes next. Manmade Constellations is a smart, magnetic, and emotional novel dedicated to the American landscape, exploring how taking to the open road teaches lessons that can’t be learned at home.

Book Description
Strategy is the art of creating value. It provides frameworks, conceptual models, and governing ideas that allow a company's managers to identify opportunities for bringing value to customers and for delivering that value at a profit. This book illustrates how new ways of creating value are being created by current global competition, changing markets, and new technologies. It shows how the focus of strategic analysis should not be the company or the industry, but the value-creating system itself, within which suppliers, business partners, allies, and customers work together to co-produce value.

Book Description
Family constellations work has broadened and developed in many different fields as a method of counseling and therapy. In addition to constellations in organizations and schools, applying this approach to working with illness and disease has expanded the potential for healing effects in the field of medicine as well. A view of transgenerational entanglements and family dynamics casts a new light on health and disease, and the insights gained from constellations with illness and health problems have led to a more holistic view of those who are ill. In Even if it Costs me my Life, Stephan Hausner aims to provide a picture of the healing potential of systemic constellations, entering into the reciprocal effects of family dynamics and illness. Extensive use of case studies demonstrates this technique in action, revealing how existing illnesses and pathologies are rooted within the family dynamic, and setting up healing postures to facilitate growth, development, and direction.

Book Description
What figures do the constellations of the night sky represent? What are the properties of the stars that they comprise? And which constellations are 'new', and which have become extinct? This unique reference book gathers together more information on the constellations than any other single work to date. The constellations can be readily compared, and a general view of them developed, using the tables that make up the first part of the book. These tables provide a wealth of information, covering all the essential properties of the constellations. In the second part of the book, each constellation is taken in turn, with a star chart and map illustrating the associated celestial figure and supported by a comprehensive list of essential properties. This highly illustrated volume provides the most complete reference to date, covering all factual aspects of the constellations for astronomers, both amateur and professional, educators and science writers.The author: Michael Bakich is currently the Planetarium Director for Kansas City Museum. He is an experienced writer and regularly writes columns for newspapers and the astronomy magazine Sky and Telescope.
