Linear Algebra for Data Science, Machine Learning, and Signal Processing English | 2024 | ISBN: 1009418149 | 453 Pages | PDF (True) | 11 MB Maximise student engagement and understanding of matrix methods in data-driven applications with this modern teaching package. Students are introduced to matrices in two preliminary chapters, before progressing to advanced topics such as the nuclear norm, proximal operators and convex optimization. Highlighted applications include low-rank approximation, matrix completion, subspace learning, logistic regression for binary classification, robust PCA, dimensionality reduction and Procrustes problems. Extensively classroom-tested, the book includes over 200 multiple-choice questions suitable for in-class interactive learning or quizzes, as well as homework exercises (with solutions available for instructors). It encourages active learning with engaging 'explore' questions, with answers at the back of each chapter, and Julia code examples to demonstrate how the mathematics is actually used in practice. A suite of computational notebooks offers a hands-on learning experience for students. This is a perfect textbook for upper-level undergraduates and first-year graduate students who have taken a prior course in linear algebra basics.  Life Course Perspectives on Black Sexual Minority Men's Health and Quality of Life English | 2026 | ISBN: 3032182328 | 402 Pages | PDF EPUB (True) | 6 MB This edited volume applies a life course framework to examine health and well-being among Black sexual minority men (SMM), a population that experiences distinct and intersecting vulnerabilities across social and cultural contexts. Although decades of U.S.-based HIV research have challenged myths about inherent risk among Black SMM, significant gaps remain in understanding the full range of their health experiences and trajectories. This book responds by situating HIV prevention within a broader continuum of infectious and chronic disease vulnerability, emphasizing the psychological, social, and historical factors that cumulatively produce vulnerability and resilience. It expands beyond a singular focus on HIV/STI risk to address broader socioecological determinants and health issues across the lifespan.  LibreOffice 26: Umfassendes Praxiswissen für Ein- und Umsteiger Deutsch | 2026 | ISBN: 3747511562 | 416 Pages | True PDF | 35 MB Der Autor Winfried Seimert zeigt Ihnen anhand vieler Beispiele die vielfältigen Anwendungsmöglichkeiten aller LibreOffice-Programme: Textdokumente mit Writer verfassen, Tabellenkalkulationen mit Calc, Präsentationen mit Impress, Zeichnungen mit Draw und Datenverwaltung mithilfe von Base.  Leverage Leadership 3.0: A Practical Guide to Building Exceptional Schools English | 2026 | ISBN: 139432443X | 507 Pages | EPUB (True) | 4 MB In the era of shrinking resources, AI and the latest high-quality curriculum materials, what separates great schools from the rest? The answer is in how a leader uses their time. Rooted in observation and training of over 40,000 school leaders worldwide, Leverage Leadership 3.0 provides school leaders with a clear, updated roadmap for achieving exceptional results.  Leitfaden Projektmanagement für Bauherren: Schritt für Schritt zum Projekterfolg Deutsch | 2026 | ISBN: 3658512326 | 530 Pages | PDF (True) | 39 MB Der Leitfaden unterstützt Bauherren dabei, auf Augenhöhe mit Planern, Projektsteuerern und ausführenden Unternehmen zu agieren und Risiken frühzeitig zu erkennen. Ziel ist es, Projekte nicht nur zu beauftragen, sondern kompetent und selbstbestimmt zu führen.  Lehren und Lernen - Tipps aus der Praxis Deutsch | 2026 | ISBN: 3662728648 | 163 Pages | PDF (True) | 1 MB In diesem Buch fasst Prof. i.R. Fouckhardt konkrete Tipps für motivierende Lehre und konzentriertes Lernen aus seiner jahrzehntelangen Lehrerfahrung zusammen: Gute Lehre hat mit Detailarbeit zu tun, mit Motivierung, guten Überleitungen, flexiblem Einsatz von Hilfsmitteln und Mut zum Fordern von Leistung. Gutes Lernen und Studieren beinhalten viel Konzentration und Übung, das Annehmen der Aufgabe, statt zu versuchen, sie zu umgehen.  Legal and Economic Practice in the Roman World, Volume I: Perspectives on Standardization and Localism English | 2026 | ISBN: 3031907981 | 264 Pages | PDF EPUB (True) | 16 MB This edited volume examines the legal and economic world of the Romans through concepts, structures, and objects that reveal practices of standardization and localism. It explores the myriad ways in which the Roman Empire became an integrated political, social and economic system.  Lectures on Complex Analysis English | 2026 | ISBN: 3032139953 | 376 Pages | PDF EPUB (True) | 53 MB This elegant textbook offers a comprehensive course on one-dimensional complex analysis. It includes many topics that, in this scope, are not covered in most other textbooks, such as a detailed investigation of the Schwarzian derivative and its associated differential equation, with applications to conformal mappings of circular polygons; various proofs of the uniformisation theorem for planar domains; an introduction to the theory of ordinary differential equations in the complex domain, culminating in a proof of the Cauchy-Kovalevskaya theorem; an introduction to the theory of normal families, including Zalcman's lemma; a proof of the Paley-Wiener theorem; a complete discussion of the Laguerre-Pólya class; solution of the Dirichlet problem, with special emphasis on harmonic measure and Green's function, and applications to conformal mappings of multiply connected domains; a detailed description of the dynamics of polynomials; and the consistent use of the theory of proper mappings whenever possible.  Lecture Notes of Professor Yuri Kagan in Theoretical Solid-State Physics English | 2026 | ISBN: 3032146208 | 544 Pages | PDF EPUB (True) | 36 MB This textbook explores foundational and cutting-edge topics in condensed matter physics. Inspired by the influential work of Prof. Yuri Kagan, the book spans key areas such as Bose-Einstein condensation, superfluid helium, crystal lattice dynamics, and phonon physics. It also addresses electronic excitations in metals and superconductors, including the BCS theory, electron-phonon interactions, and metallic hydrogen. Professor Maxim Kagan extends this work with advanced lectures on strongly correlated electron systems, quantum hydrodynamics, and mechanisms of unconventional superconductivity. The book concludes with a focus on groundbreaking research by Prof. Yuri Kagan, covering topics such as quantum gases, metallic hydrogen, and high-temperature superconductivity. This textbook serves as both a tribute to Prof. Kagan's legacy and a comprehensive resource for students and researchers in theoretical condensed matter physics.  Learning in the Postdigital Knowledge Society: Between Textbooks, Social Media and AI English | 2026 | ISBN: 3032219558 | 240 Pages | PDF EPUB (True) | 3 MB This Open Access book explores the evolving dynamics of postdigital learning in Central and Eastern Europe (CEE), offering a comprehensive ethnographic and discursive analysis. Through an exploration of educational media - including traditional tools and AI-driven technologies - it examines how public schooling, identity formation and neoliberal influences intersect within post-transitional societies. |
