As the first volume of a two-volume set that presents a comprehensive syntactical picture of Singapore Mandarin, this title discusses the distinguishing characteristics of the Chinese language and describes the grammar of Singapore Mandarin. The book first provides an overview of the grammar of Singapore Mandarin and compares it with Chinese Mandarin (Putonghua). As a variety of Mandarin Chinese, Singapore Mandarin is also characterised by syntactic rules taking precedence over morphological rules. Therefore, it is argued that word order and functional words are specifically important in the study of Singapore Mandarin. Then the author explicates the properties and functions of the following nine grammatical components: the five most basic phrase types, word classes, sentences, subjects and predicates, predicates and objects, predicates and complements, attributes and adverbials, complex predicate phrases, and prepositions and prepositional phrases. With rich and authentic language examples, the book will serve as a must-read for learners and teachers of Mandarin Chinese and linguistics scholars interested in global Chinese and especially Singapore Mandarin.
As the second volume of a two-volume set that presents a comprehensive syntactical picture of Singapore Mandarin, this title analyses various expressions relating to number, quantity, time and place, composite sentences and the characteristics and standardisation of Singapore Mandarin. The first two chapters discuss expressions of number, quantity, time and place in Singapore Mandarin and touch upon the differences in these expressions between Singapore and Chinese Mandarin (Putonghua). Composite sentences are then analysed, covering seven types of compound sentences and eight types of complex sentences, as well as connective words with a focus on conjunctions. The final part of the volume analyses the characteristics of Singapore Mandarin grammar compared with Chinese Mandarin, on the level of phrase, lexicon and sentence. From the perspectives of language contact, political and social contexts and bilingualism, it summarises the possible reasons for the differences between the two varieties of Chinese and points out primary challenges and major concerns of the standardisation of Singapore Mandarin. With rich and authentic language examples, the book will serve as a must read for learners and teachers of Mandarin Chinese and linguistics scholars interested in global Chinese and especially Singapore Mandarin.
This book explores the history of mechanical engineering since the Bronze Age. Focusing on machinery inventions and the development of mechanical technology, it also discusses the machinery industry and modern mechanical education. The evolution of machinery is divided into three stages: Ancient (before the European Renaissance), Modern (mainly including the two Industrial Revolutions) and Contemporary (since the Revolution in Physics, especially post Second World War). The book not only clarifies the development of mechanical engineering, but also reveals the driving forces behind it – e.g. the economy, national defense and human scientific research activities – to highlight the links between technology and society; mechanical engineering and the natural sciences; and mechanical engineering and related technological areas. Though mainly intended as a textbook or supplemental reading for graduate students, the book also offers a unique resource for researchers and engineers in mechanical engineering who wish to broaden their horizons.
Puxian is one of the Min dialects in China. This book investigates the function of pronominal expressions in Puxian, focusing especially on three prominent issues in the linguistic literature, viz. impersonal reference, self-forms and person effects on word order. The investigation of impersonality deals with a group of constructions in Puxian that have pronominalized subjects but crucially with impersonal reference. By means of careful examination, these subjects are, for the first time, projected onto five semantic domains on a connected loop. The discussion on self-forms in Puxian focuses on their interrelated functions along the pathway of grammaticalization, such as reflexivity, intensification, viewpoint markings, verbal manner, etc. Significantly, this discussion is based on the latest functional-typological perspectives, which is different from previous approaches to Mandarin ziji. The attention to word order and person effect is related to the polyfunctional morpheme k?21, which plays a part in several constructions, ranging from the monotransitives, ditransitives, causatives, passives and even to the intransitives. The main concern is how the grammatical category of person as a whole may affect the placement of syntactic constituents as well as encodings of argument roles by means of the morpheme k?21. Since Puxian has been relatively unknown in linguistics, a sketch of Puxian grammar and language situation is also offered in this book.
This book focuses on adaptive iterative learning control problem for nonlinear time-delay systems.A universal adaptive learning control scheme is provided for a wide classes of nonlinear systems with time-varying delay and input nonlinearity. Proceeding from easy to difficult, this book deals with the adaptive iterative learning control problems for parameterized nonlinear time-delay systems, non-parameterized nonlinear time-delay systems, nonlinear time-delay systems with unknown control direction and nonlinear time-delay systems with un-measurable states. The proposed control schemes can be extended to the adaptive learning control problem for wider classes of nonlinear systems revelent to abovementioned nonlinear systems.The topics presented in this book are research hot spots of iterative learning control. This book will be a valuable reference for researchers and students working or studying in this area.
This book provides an introduction to recent advances in theory, algorithms and application of Boolean map distance for image processing. Applications include modeling what humans find salient or prominent in an image, and then using this for guiding smart image cropping, selective image filtering, image segmentation, image matting, etc. In this book, the authors present methods for both traditional and emerging saliency computation tasks, ranging from classical low-level tasks like pixel-level saliency detection to object-level tasks such as subitizing and salient object detection. For low-level tasks, the authors focus on pixel-level image processing approaches based on efficient distance transform. For object-level tasks, the authors propose data-driven methods using deep convolutional neural networks. The book includes both empirical and theoretical studies, together with implementation details of the proposed methods. Below are the key features for different types of readers. For computer vision and image processing practitioners: Efficient algorithms based on image distance transforms for two pixel-level saliency tasks; Promising deep learning techniques for two novel object-level saliency tasks; Deep neural network model pre-training with synthetic data; Thorough deep model analysis including useful visualization techniques and generalization tests; Fully reproducible with code, models and datasets available. For researchers interested in the intersection between digital topological theories and computer vision problems: Summary of theoretic findings and analysis of Boolean map distance; Theoretic algorithmic analysis; Applications in salient object detection and eye fixation prediction. Students majoring in image processing, machine learning and computer vision: This book provides up-to-date supplementary reading material for course topics like connectivity based image processing, deep learning for image processing; Some easy-to-implement algorithms for course projects with data provided (as links in the book); Hands-on programming exercises in digital topology and deep learning.
