Free Download Spatial-Temporal Evolution of Mining-Induced Rock Damage and Ground Control of Roadways English | 2025 | ISBN: 9819654386 | 245 Pages | PDF (True) | 18 MB This open access book presents the Coal remains the primary energy source in China, with an estimated total coal reserve of 59 trillion tons at depths of less than 2000 meters. Among these, over 50% lie at depths exceeding 1000 meters, primarily distributed in central and eastern China. Deep coal mining has become the new norm for the coal industry's development and resource exploitation. To ensure energy supply for the rapid economic development of central and eastern regions, mining coal resources from depths of over 1000 meters is inevitable. This endeavor holds significant strategic importance for safeguarding national energy security and supporting regional economic growth. However, mining-induced hazards, such as rock bursts, water inrushes, and roof collapses, continue to occur frequently in both local and state-owned coal mines. These incidents pose severe threats to the safety of coal production, tarnish the reputation of China's mining industry, and hinder its development. Therefore, advancing mining engineering-especially the theories of major accident prediction and control-is essential. A deeper understanding of the dynamic processes underlying mining-induced pressure and strata movement is necessary. Promoting safe and efficient coal mining through informed decision-making and management supported by scientific, quantitative methods is a critical and urgent task. Achieving informatization, intelligence, and visualization in mining operations will be key to fundamentally addressing the current safety challenges in China's mining industry. In recent years, the author and their team have conducted in-depth studies on models of dynamic disasters and surrounding rock control in deep mines, supported by projects under the National Basic Research Program (973 Program), the National Key R&D Program, as well as talent and general research funds and specialized consultancy projects from the Chinese Academy of Sciences. The main research focuses include constructing spatial structural models of overlying strata in mining areas, analyzing the spatiotemporal evolution of mining-induced stress, and developing proactive control technologies for dynamic disasters in mining areas. This book aims to provide foundational insights into the occurrence and control of major mining accidents. It proposes a decision-making framework for predicting and managing such disasters by controlling the movement of surrounding rock and stress conditions induced by mining. These efforts are expected to provide a reference for advancing research in related fields.  Free Download Spatial Economic Modelling: An Introduction to Key Competition Models English | 2025 | ISBN: 3031827864 | 279 Pages | PDF EPUB (True) | 8 MB The book aims to provide a step-by-step guide to learning and implementing spatial modelling. It provides a concise history of the spatial approach and a self-contained primer chapter on the key game theory tools required to undertake spatial analysis. It then provides a comprehensive explanation of the key traditions and models, including the Hotelling model and related Salop circle model, and demonstrates their various applications to consumer, firm and market interactions. Topics covered in the book include: product differentiation, the physical location of firms, spatial price discrimination, oligopolistic competition, non-uniform distributions of consumers, political competition and the basic Downs model, and the application of spatial models to marketing and management. This book will be a valuable resource for undergraduate students in microeconomics and applied economics, particularly on industrial organization courses.  Free Download Sparks for Innovation: Why Hackathons Work and How to Organize One by Maciej Ryś English | May 11th, 2025 | ISBN: 0231214685 | 232 pages | True EPUB | 0.65 MB Hackathons-participatory gatherings in which people with various backgrounds and experiences come together to address a challenge or create something new in a limited period of time-have become an important part of today's technological, social, and business landscapes. They originated in IT and have since spread into other fields including medicine, law, biology, environment, education, and civic engagement. How and why can hackathons drive innovation? How can they challenge the status quo? What role can they play in an organization's strategy? Under what conditions are hackathons most effective, and what are their limitations?  Free Download Lu Ann Homza, "Spanish Inquisition, 1478-1614: An Anthology of Sources" English | ISBN: 0872207943 | 2006 | 320 pages | PDF | 1286 KB This collection of previously untranslated court documents, testimonials, and letters portrays the Spanish Inquisition in vivid detail, offering fresh perspectives on such topics as the Inquisition's persecution of Jews and Muslims, the role of women in Spanish religious culture, the Inquisition's construction and persecution of witchcraft, daily life inside an Inquisition prison, and the relationship between the Inquisition and the Spanish monarchy. Headnotes introduce the selections, and a general introduction provides historical, political, and legal context. A map and index are included.
