This book is written based on authors' research on cement hydration during the past decade. It establishes simulation model to evaluate the influence of crystal defects on the dissolution of tricalcium silicate and morphology change of particles and explores the hydration kinetics and microstructure development of tricalcium silicate under the mixed control of dissolution, diffusion, as well as boundary nucleation and growth. It also provides a theoretical basis for regulating the microstructure and performance of cement-based materials. It is designed as a reference work for professionals or practitioners and as a textbook for undergraduates or postgraduates. This book provides valuable knowledge and useful methods that can be applied in the field of cement hydration.

Visual Question Answering (VQA) usually combines visual inputs like image and video with a natural language question concerning the input and generates a natural language answer as the output. This is by nature a multi-disciplinary research problem, involving computer vision (CV), natural language processing (NLP), knowledge representation and reasoning (KR), etc.Further, VQA is an ambitious undertaking, as it must overcome the challenges of general image understanding and the question-answering task, as well as the difficulties entailed by using large-scale databases with mixed-quality inputs. However, with the advent of deep learning (DL) and driven by the existence of advanced techniques in both CV and NLP and the availability of relevant large-scale datasets, we have recently seen enormous strides in VQA, with more systems and promising results emerging.This book provides a comprehensive overview of VQA, covering fundamental theories, models, datasets, and promising future directions. Given its scope, it can be used as a textbook on computer vision and natural language processing, especially for researchers and students in the area of visual question answering. It also highlights the key models used in VQA.

The author is a profound Chinese political dissident who spent his whole life fighting the the communist evil in China. This book is a collection of his studies on religions, philosophy,history and politics,sciences, ect. He use many styles in his expression including tales, poetry, editorial, commentary, humor and many more. This transforms the penetrating deep thoughts into the simple language that the general public has no difficulty to grasp the values of wisdom.The author is a rare master of traditional Chinese language. He reveal many secrets of the ancient China culture. Those secrets have profound science implications. Some of the articles are master pieces of ancient Chinese language, which makes them not only rich in thinking, but beauty in literature.He predicted many major world events and see through all the fronts and tell the whole truth.Even though his work has been well known on the internet but disrupted by the regime's influence from publishing in the Chinese community.

The book presents selected papers at the 9th Conference on Sound and Music Technology (CSMT) held virtually in June 2022, organized by Zhejiang University, China. CSMT is a multidisciplinary conference focusing on audio processing and understanding with bias on music and acoustic signals. The primary aim of the conference is to promote the collaboration between art society and technical society in China. In this book, the paper included covers a wide range topic from speech, signal processing, music understanding, machine learning, and signal processing for advanced medical diagnosis and treatment applications, which demonstrates the target of CSMT merging arts and science research together. Its content caters to scholars, researchers, engineers, artists, and education practitioners not only from academia but also industry, who are interested in audio/acoustics analysis signal processing, music, sound, and artificial intelligence (AI).

This brief proposes that the keys to internet cross-layer optimization are the development of non-standard implicit primal-dual solvers for underlying optimization problems, and design of jointly optimal network protocols as decomposition of such solvers. Relying on this novel design-space oriented approach, the author develops joint TCP congestion control and wireless-link scheduling schemes for wireless applications over Internet with centralized and distributed (multi-hop) wireless links. Different from the existing solutions, the proposed schemes can be asynchronously implemented without message passing among network nodes; thus they are readily deployed with current infrastructure. Moreover, global convergence/stability of the proposed schemes to optimal equilibrium is established using the Lyapunov method in the network fluid model. Simulation results are provided to evaluate the proposed schemes in practical networks.

Being infrastructure-less and without central administration control, wireless ad-hoc networking is playing a more and more important role in extending the coverage of traditional wireless infrastructure (cellular networks, wireless LAN, etc). This book includes state-of the-art techniques and solutions for wireless ad-hoc networks. It focuses on the following topics in ad-hoc networks: vehicular ad-hoc networks, security and caching, TCP in ad-hoc networks and emerging applications. It is targeted to provide network engineers and researchers with design guidelines for large scale wireless ad hoc networks.

This book about fossil plants of prehistoric angiosperms offers the newest research on their origin. It emphasizes the early Cretaceous and Jurassic materials and integrates multiple techniques to study the morphology, anatomy and phylogeny of the fossils.

Xin Wang studies the new operational transportation planning problems that arise in the context of cooperation in both static and dynamic scenarios. To achieve the cost-savings embedded in cooperation, novel planning approaches that can help forwarders obtaining high-quality solutions are proposed.

Higher Education as a Field of Study in China: Defining Knowledge and Curriculum Structure concerns the complexity of higher education as an academic field_the evolving nature of the field in light of the overall development of higher education in China. It reviews how higher education as a field of study has evolved in China since 1978 and how the field has been shaped by political and social forces, as well as institutional culture. Xin Wang argues that higher education is becoming an interdisciplinary field rather than a subfield under the discipline of education, especially when higher education has become an enterprise with such a broad scope in China. Wang also expresses a belief that the field of higher education is being challenged by the professional need for preparing and training competent professionals for various administrative positions in China. Higher education as a field will be professionalized with its own knowledge base and a set of skills in applying this knowledge to practical areas. This book also provides an account of the U.S. model of higher education as an example_how the field was formed and developed, how it has evolved from a generalized area of inquiry into a professional specialization, how programs of higher education are structured, what classes they offer, and what challenges they face. The U.S. model presents a comparative perspective for Chinese scholars and program directors about higher education as a field of study.
