This Brief reviews contemporary research conducted in university and industry laboratories on thermal management in electrochemical energy storage systems (capacitors and batteries) that have been widely used as power sources in many practical applications, such as automobiles, hybrid transport, renewable energy installations, power backup and electronic devices. Placing a particular emphasis on supercapacitors, the authors discuss how supercapacitors, or ultra capacitors, are complementing and replacing, batteries because of their faster power delivery, longer life cycle and higher coulombic efficiency, while providing higher energy density than conventional electrolytic capacitors. Recent advances in both macro- and micro capacitor technologies are covered. The work facilitates systematic understanding of thermal transport in such devices that can help develop better power management systems.
Pudong is a district located at east of the Huangpu River and is opposite to Puxi, west of the Huangpu River and the historic city center of Shanghai. Since the establishment of Pudong New Area in early 1990s, the backward Pudong has become a thriving financial hub of modern China and home to the Lujiazui Finance and the Pilot Free-Trade Zone, and the Shanghai Stock Exchange. This book sets Pudong in a broad historical background and records the historical changes and various details and legends in the Pudong's development process. It reflects the tortuous process of China's reform and is the first book detailing the complete history of Pudong. It offers suggestions that can be popularized and emulated to achieve significant development across China.
Two-stage single-phase converters, including two-stage single-phase dc-ac inverters and two-stage single-phase PFC converters, are interfacing power converters between dc and ac voltage/current sources, which have been widely applied for dc-ac and ac-dc power conversion. For the two-stage single-phase converter, the ac-side power pulsates at twice the ac voltage frequency, resulting in second harmonic current (SHC) which might flow into the dc-dc converter, the dc voltage source, and dc load. This book clarifies the generation, propagation, and side-effects of this SHC and proposes the SHC reduction control schemes for the dc-dc converter, with different topologies and/or different operating modes, in the single-phase converter. On this basis, the second harmonic current compensator (SHCC) is proposed to compensate the SHC, significantly reducing the dc bus capacitance. In doing so, the electrolytic capacitors, with short lifetimes, are removed from the two-stage single-phase converter, leading to extended system lifetime and enhanced system stability. For having flawless SHC compensation performance, the port-current control schemes are proposed for the SHCC. Additionally, the stability analysis is carried out for the two-stage single-phase converter with the addition of SHCC. This book is a monograph combining theoretical analysis and engineering design, which could not only be a reference book for master students, Ph.D. students, and teachers majoring in power electronics but also be a handbook for the electrical engineers working on the research and development of LED drivers, EV on-board chargers, railway auxiliary power supplies, aviation power supplies, renewable energy generation systems, etc.
Exploration, Identification and Utilization of Barley Germplasm explores the timely global challenges related to barley production posed by the narrowing of biodiversity and problem soils, identifying elite genotypes which will enhance barley breeding and be essential to genetic and evolution studies. The book covers the utilization of barley germplasm for improving the quality of both food and feed barley as well as exploring and utilizing varieties of germplasm that are tolerant to drought, waterlogged, salt, and acid soil. Chapters are devoted to prime strategies for future research, including identifying barley germplasm by applying Omics, exploring barley germplasm by means of the Focused Identification of Germplasm Strategy (FIGS), and creating barley germplasm through mutation. Users will find this book to be a key research reference for both professionals and academics, providing a comprehensive update for established barley researchers that equips them with an understanding of the new methodologies needed for innovation and discovery, while also providing a helpful entry to the subject for young researchers and students. - Provides a one-stop shop to acquire a speedy overview of the main and recently applied issues of barley breeding - Provides newly-developed methodologies in barley germplasm research - Describes special genotypes from wild barley, including Tibetan wild barley, which show a high tolerance to abiotic stresses and carry different alleles from cultivated barley
This book proposes a comparative analysis between the urban forms of Algiers and Nanjing. It underscores the different evolutions of the two cities and explains the relation between their spatial structures and the major urban issues they are currently facing. Moreover, it explores the similarities in and differences between their physical structures in order to provide an accurate description of the type and extent of their growth.The book employs a qualitative and quantitative approach and combines a range of morphological methods such as historico-geographical, spatial configuration (space syntax), typo-morphological, remote sensing and cellular automata in order to extensively explore the urban issues that Algiers and Nanjing are now experiencing. This approach can be a helpful “role model” in the field of spatial and geometrical analysis of cities, which is often complex and a source of ambiguity for researchers. Moreover, the approach will help readers understand the place and the exact role of the different urban issue’s components, thus to appreciate the signifying or instigating side.
