English | 2022 | ISBN: 1787756203 | 226 pages | True PDF EPUB | 6.26 MB Postnatal PTSD, often referred to as birth trauma, is an underdiagnosed and misunderstood condition. Often mistaken for postnatal depression and with 4% of women developing the condition after giving birth, it is essential that health professionals learn to recognise and prevent postnatal PTSD.  English | 2021 | ISBN: 1617296694, 978-1935182269 | 704 pages | True PDF , MOBI| 53.16 MB Whether you're canvassing a congressional district, managing a sales region, mapping city bus schedules, or analyzing local cancer rates, thinking spatially opens up limitless possibilities for database users. PostGIS, a freely available open-source spatial database extender, can help you answer questions that you could not answer using a mere relational database. Its feature set equals or surpasses proprietary alternatives, allowing you to create location-aware queries and features with just a few lines of SQL code.  English | 2022 | ISBN: 0367775158, 036777514X | 239 pages | True PDF | 6.62 MB This book shows readers how to rethink and reimagine leadership and charts a course towards a new vision of leadership. It outlines lessons to be learned for leadership – not only after the COVID pandemic but also in light of other ongoing crises around issues such as climate change and global inequality.  English | 2022 | ISBN: 1527579697, 978-1527579699 | 412 pages | True PDF | 2.98 MB This book introduces and develops post-Newtonian kinetic and phenomenological theories in a self-contained manner. The starting point for phenomenological theory is Einstein's field equations from which the first and second post-Newtonian approximations are derived. Within phenomenological theory, Eulerian hydrodynamic equations are obtained and the conservation laws are derived. The kinetic counterpart of the theory is developed within the framework of Boltzmann equation, where the post-Newtonian equilibrium distribution function and the hydrodynamic equations are determined. Some astrophysical applications of post-Newtonian hydrodynamic equations, such as stellar structure models for stars, the spherically symmetrical accretion of a gas into a massive object, the Jeans instability (which is responsible for the collapse of interstellar gas clouds), and the galaxy rotation curves, are presented and the importance of post-Newtonian corrections is discussed. This book will be helpful not only as a text for advanced courses, but also as a reference for physicists, astrophysicists, and applied mathematicians who are interested in the phenomenological and kinetic post-Newtonian theory and its applications.

English | 2022 | ISBN: 1636393101 | 152 pages | True PDF | 9.18 MB Machine learning and artificial intelligence (AI) are powerful tools that create predictive models, extract information, and help make complex decisions. They do this by examining an enormous quantity of labeled training data to find patterns too complex for human observation. However, in many real-world applications, well-labeled data can be difficult, expensive, or even impossible to obtain. In some cases, such as when identifying rare objects like new archeological sites or secret enemy military facilities in satellite images, acquiring labels could require months of trained human observers at incredible expense. Other times, as when attempting to predict disease infection during a pandemic such as COVID-19, reliable true labels may be nearly impossible to obtain early on due to lack of testing equipment or other factors. In that scenario, identifying even a small amount of truly negative data may be impossible due to the high false negative rate of available tests. In such problems, it is possible to label a small subset of data as belonging to the class of interest though it is impractical to manually label all data not of interest. We are left with a small set of positive labeled data and a large set of unknown and unlabeled data.  English | 2022 | ISBN: 1526785692 | 162 pages | True PDF EPUB | 186.01 MB "In a book of Porsche photography and engaging conversation, Lance Cole journeys through a personal passion for Porsche –one that many supercar enthusiasts share. Herein light falls on sculpted metal and paint – shiny and less shiny. Throwing off the conventions of Porsche purism, yet at the same time always respecting the origins of Porsche, and the status of the 911, this is a book that celebrates the engineering and the design language of Porsche amid its culture. From an "oily-rag" 356 to old 911s and new 911s, with a brief alighting upon other cars of the Porsche clan, this is an eclectic collection of enthusiasts "moments" captured across a British Porsche landscape."  English | 2022 | ISBN: 1771602694 | 160 pages | True EPUB | 347.33 MB Popular Day Hikesis a series of bestselling books written for visitors and locals looking to hike scenic trails from well-established staging areas.Popular Day Hikes: Watertoncovers 34 hikes in southern Alberta's beautiful Waterton Lakes National Park. From short, easy walks, to longer, full-day hikes, to easy scrambles, this book outlines mountain trips for all ages and all levels of difficulty. Some of the hikes included are:  English | 2022 | ISBN: 1486314864 | 94 pages | True PDF EPUB | 54.54 MB This book stinks. we think you'll love it!  English | 2023 | ISBN: 036756520X | 190 pages | True PDF EPUB | 230.53 MB Working out solutions to polynomial equations is a mathematical problem that dates from antiquity. Galois developed a theory in which the obstacle to solving a polynomial equation is an associated collection of symmetries. Obtaining a root requires "breaking" that symmetry. When the degree of an equation is at least five, Galois Theory established that there is no formula for the solutions like those found in lower degree cases. However, this negative result doesn't mean that the practice of equation-solving ends. In a recent breakthrough, Doyle and McMullen devised a solution to the fifth-degree equation that uses geometry, algebra, and dynamics to exploit icosahedral symmetry. Polynomials, Dynamics, and Choice: The Price We Pay for Symmetry is organized in two parts, the first of which develops an account of polynomial symmetry that relies on considerations of algebra and geometry. The second explores beyond polynomials to spaces consisting of choices ranging from mundane decisions to evolutionary algorithms that search for optimal outcomes. The two algorithms in Part I provide frameworks that capture structural issues that can arise in deliberative settings. While decision-making has been approached in mathematical terms, the novelty here is in the use of equation-solving algorithms to illuminate such problems. Features Treats the topic—familiar to many—of solving polynomial equations in a way that's dramatically different from what they saw in school Accessible to a general audience with limited mathematical background Abundant diagrams and graphics. |
