Free Download Philosophy of Mathematics in Antiquity and in Modern Times
English | 2023 | ISBN: 3031273036 | 314 Pages | PDF (True) | 8 MB
Philosophy of Mathematics is understood, in this book, as an effort to clarify such questions that mathematics itself raises but cannot answer with its own methods. These include, for example, questions about the ontological status of mathematical objects (e.g., what is the nature of mathematical objects?) and the epistemological status of mathematical theorems (e.g., from what sources do we draw when we prove mathematical theorems?). The answers given by Plato, Aristotle, Euclid, Descartes, Locke, Leibniz, Kant, Cantor, Frege, Dedekind, Hilbert and others will be studied in detail. This will lead us to deep insights, not only into the history of mathematics, but also into the conception of mathematics as it is commonly held in the present time.

English | 2023 | ISBN: 9819920612 | 747 Pages | PDF EPUB (True) | 55 MB
This contributed volume discusses the current status of the occurrences, fate and transport of persistent pollutants in water and wastewater. This contents compile the state-of-the-art of emerging technologies such as nanotechnology, advanced oxidation process, membrane processes, sorption, etc. for the clean-up of persistent pollutants in water including heavy metals, pharmaceuticals, phenolic compounds as well as microplastics and their by-products. This volume will be useful as a guide for the researchers to build strategies to deal with persistent pollutant. It also discusses the principal aspects of degradation mechanism of the pollutants, toxic by-products and effectiveness of the emerging technologies. This volume will be a useful guide for those working in soil and water protection, and environmental civil engineering.

Free Download Persian Blues, Psychoanalysis and Mourning
English | 2023 | ISBN: 1032215941 | 159 Pages | PDF | 5 MB
Homayounpour is simultaneously Shahrzad, the fearless storyteller, and Shahrzad's analyst: subjecting fairy tales to fierce new insights, while weaving an indigo thread through her own devastation on the death of her father and the wonders and horrors of motherhood. A blue thread, or melody, runs though the separations and emigrations of her family and patients driven or broken apart by war, and likewise through the fraught world inhabited by Persian women. This book breaks new psychoanalytic ground, offering a radical rejection of traditional clichés about Iran, and Iranian women, but its unsparing elegance transcends any political agenda, bridging the ocean of a shared and tragic humanity.

Free Download Permanent Magnet Synchronous Machines and Drives: Flux Weakening Advanced Control Techniques
English | 2023 | ISBN: 1032330651 | 279 Pages | PDF (True) | 31 MB
Permanent magnet synchronous motors (PMSMs) are popular in the electric vehicle industry due to their high-power density, large torque-to-inertia ratio, and high reliability. This book presents an improved field-oriented control (FOC) strategy for PMSMs that utilizes optimal proportional-integral (PI) parameters to achieve robust stability, faster dynamic response, and higher efficiency in the flux-weakening region. The book covers the combined design of a PI current regulator and varying switching frequency pulse-width modulation (PWM), along with an improved linear model predictive control (MPC) strategy. Researchers and graduate students in electrical engineering, systems and control, and electric vehicles will find this book useful.

Free Download Performance Analysis and Optimization of Parallel Manipulators
English | 2023 | ISBN: 9819905419 | 303 Pages | PDF (True) | 11 MB
This book investigates the performance analysis and optimization design of parallel manipulators in detail. It discusses performance evaluation indices for workspace, kinematic, stiffness, and dynamic performance, single- and multi-objective optimization design methods, and ways to improve optimization design efficiency of parallel manipulators. This book collects the authors' research results previously scattered in many journals and conference proceedings and presents them in a unified form after the methodical edition. As a result, numerous performance analyses and optimization of parallel manipulators are presented, in which the readers in the robotics community may be greatly interested. More importantly, readers can use the methods and tools introduced in this book to carry out performance evaluation and optimization of parallel manipulators by themselves. The book can provide important reference and guideline for undergraduate and graduate students, engineers, and researchers who are interested in design and application of parallel manipulators.

Perform Suzhou is a task- and performance-oriented textbook course for Chinese study abroad programs serving intermediate- to advanced-level learners.Performance is the key concept; developing communication skills through role playing. Field performance tasks enable students learning Chinese to refine and solidify communication skills by executing real-life tasks in the target culture, before reporting on their experiences in the classroom. The dialogues presented form the basis for improvisation for related contexts, equipping students to respond appropriately in new situations. Perform Suzhou is composed of staged units, drills, exercises and culture notes with accompanying audio.The textbook is accompanied by audio and Action! China, the supporting workbook.

Free Download Pedicled Flaps in Partial Breast Reconstruction
English | 2023 | ISBN: 3031084829 | 452 Pages | PDF EPUB (True) | 137 MB
Breast cancer is one of the most common cancer forms worldwide and has become the commonest cancer in women in most parts of the world. Surgery remains the single best treatment modality and globally, breast conservations are on the rise with increasing Oncoplastic techniques. Oncoplastic techniques have evolved over the last decade with the increasing use of pedicled flaps to enable partial breast reconstruction. This handy guide fills a gap in available publications to describe current trends, to help advance the knowledge and update skills of the reader. After an historical introduction, chapters on pre-operative mapping and imaging, as well as on patient selection for each approach, over eleven chapters are devoted to specific flaps and to their combination. The crucial management of complications and radiotherapy planning are also developed in dedicated parts. With contributions from world-renowned plastic and oncoplastic breast surgeons, step-by-step videos linked to the surgical chapters and a wealth of original photographs and illustrations, Pedicled Flaps in Partial Breast Reconstruction will be a valued reference for fellows, residents, practicing and highly experienced plastic surgeons, breast surgeons, and practitioners in related surgical sub-specialties, who will find this a useful tool in their day-to-day practice.
