History, Calendar and Skylore of the Incas at the Time of the Spanish Conquest
English | 2026 | ISBN: 3032123151 | 559 Pages | PDF (True) | 60 MB
A significantly expanded translation of the author's Pachap vnancha: El calendario metropolitano del Estado Inca, this book is the culmination of several decades of research on Andean calendar-astronomical systems and their role in the ceremonial, economic and political aspects of the region's pre-Hispanic societies. This book presents a reconstruction of the state calendar used in Inca Tahuantinsuyu for purposes of programming, coordination and control of various social activities on an imperial scale. Although the correlation between Mesoamerican calendars and the Julian calendar has long been used to interpret events in that part of the world, this work is the first of its kind for the Andean region.

History of Mathematical Sciences: Portugal and East Asia VI: Measuring Time, Heaven and Earth
English | 2026 | ISBN: 3032140269 | 305 Pages | PDF EPUB (True) | 66 MB
This book presents high-quality papers on the History of Mathematical Sciences, focusing on Portugal and East Asia, a testament to ongoing international collaboration in uncovering the rich, interwoven histories of science, culture, and diplomacy across continents. This volume explores the profound impact of mathematical and scientific exchanges between Europe, and in particular, Portugal, and East Asia, emphasizing how time, space, and cosmological understanding were shaped and transformed through intercultural contact. Chapters range from Jesuit mechanical clocks in Japan to reinterpretations of Euclidean logic in Chinese translations, from the mapping of early Portuguese planispheres to Qing dynasty astronomical reform. Featuring contributions by leading historians of science, this collection sheds light on the individuals-Jesuits, scholars, artisans-who bridged cultures and shaped knowledge across early modern Eurasia. It offers a unique lens into how mathematics and cosmology were not only tools of measurement but also vehicles of cross-cultural dialogue and power. This book is essential for historians of science, mathematics, and East-West relations.

History of Earth Sciences
English | 2026 | ISBN: 1789452317 | 317 Pages | PDF (True) | 32 MB
The creation of the Comité français d'histoire de la géologie (COFRHIGEO) in 1976 aimed to convene geologists, philosophers and historians interested in contributing to a written history of geology, which was at that time still in its infancy.

High-Performance Computing and Artificial Intelligence in Process Engineering
English | 2025 | ISBN: 0750361727 | 309 Pages | PDF EPUB (True) | 82 MB
High-performance computing (HPC) and artificial intelligence (AI) in process engineering involve complex system modelling, data analysis, optimization design, and real-time monitoring. Key methods include data integration, model construction, optimization algorithms, machine learning, deep learning, parallel computing, and real-time analytics. These techniques significantly enhance production efficiency, reduce costs, and improve system stability. They also promote industrial intelligence, creating new opportunities and challenges in process engineering. This integration supports the advancement of Industry 4.0 and smart manufacturing.

High Performance Spark: Best Practices for Scaling and Optimizing Apache Spark
English | 2026 | ISBN: 1098145852 | 442 Pages | EPUB | 6 MB
Apache Spark is amazing when everything clicks. But if you haven't seen the performance improvements you expected or still don't feel confident enough to use Spark in production, this practical book is for you. Authors Holden Karau, Adi Polak, and Rachel Warren walk you through the secrets of the Spark code base and demonstrate performance optimizations that will help your data pipelines run faster, scale to larger datasets, and avoid costly antipatterns.

English | 2021 | ISBN: 0750324627 | 337 Pages | EPUB (True) | 21 MB
This book presents both the essentials of magnetically confined plasma physics, as well as the powerful sources of high-frequency coherent radiation used for electron cyclotron resonance heating (ECRH), electron cyclotron resonance current drive (ECRCD), and for plasma ignition, control, and diagnostics in different fusion devices.

High Entropy Alloys: Fundamentals and Recent Advances
English | 2026 | ISBN: 9819202515 | 420 Pages | PDF EPUB (True) | 59 MB
This book presents the history and the evolution of high entropy alloys. It discusses the properties, microstructure, and applications of these alloys. The basic introduction to high entropy alloys and their important effects are also presented. Various metallurgical techniques starting from the traditional to advanced techniques used to prepare high entropy alloys the chances of forming various possible phases and their predictions using different methods are presented. Advanced instruments used to characterize microstructural, mechanical, corrosion, wear, and oxidative resistance are outlined in this book. One of the very important, and commonly used high entropy alloys synthesis methods; ball milling, is also presented. The book includes interesting chapter on electrochemical sensor applications of high entropy alloy powders- a very advanced and new application, useful for detecting toxic dyes, chemicals, and bio-active compounds. Finally, the book presents 'high entropy oxides', it's introduction, properties and applications.

Higgs Boson: A Mathematical Survey with Finite Element Method
English | 2023 | ASIN: B0CKC434M3 | 99 Pages | PDF | 5 MB
In this book, the finite difference, finite element and the root finding approximations i.e. Newton, Quasi Newton and Broyden methods has been presented. We also consider the finite difference/finite element hybrid method to solve the wave equation in Einstein and de Sitter space-time. The mathematical model of the Higgs Boson equation in de Sitter space-time has been presented as a chapter. Finally, the finite difference/finite element solution using Newton linearization method has been presented.

Heterodox Economics
English | 2026 | ISBN: 1788218159 | 148 Pages | PDF | 1 MB
Heterodox economics differs from orthodox or mainstream economics. It draws on a multiplicity of ideas, disciplines, methods and voices to present a more radical alternative to the dominant paradigm of neoclassical economics, which is viewed as overly narrow and blind-sided to how economies actually work.
