Das Buch widmet sich populären Musikdiskursen aus einer interdisziplinären diskurslinguistischen und korpuspragmatischen Perspektive. Es wird die Frage gestellt, wie Phänomene, die als schwer benennbar oder auch als unsagbar gelten, mit Worten beschrieben und bewertet werden: Musik und Klang nämlich, sowie ihr ästhetisches Erleben und ihre kulturelle Bedeutung. Ca. 13.500 Musikrezensionen unterschiedlicher Genres zwischen Pop und Klassik werden vor diesem Hintergrund untersucht. Zentrum des Interesses ist die Art und Weise der sprachlich-diskursiven Konstituierung musikalisch-ästhetischer Diskursobjekte und Kategorien im Verhältnis zum Metadiskurs der Unsagbarkeit von Musik. Das Augenmerk richtet sich dabei auf die Spezifik des diskursiven Sprach- und Zeichengebrauchs, vor allem in Kollokationen, nominalen Wortverbindungen und attributiven Clustern. Die Korpusanalysen zeigen erstmals empirisch, wie Musik im Diskurs mit sprachlichen Mustern, sprachlicher Kreativität und Dichte verwoben ist, wenn über musikalische Eigenschaften und klangliche Eigenheiten gesprochen bzw. geschrieben wird. Die Ergebnisse geben nicht zuletzt Aufschluss über das Verhältnis von Musterhaftigkeit und Diversität im Sprachgebrauch.

A Quantum Dot Sensitized Solar Cell employing ternary or quaternary quantum dots represents an innovative approach to solar energy conversion. In this design, the utilization of three or four distinct types of quantum dots enables the solar cell to efficiently capture a broader spectrum of light. This enhanced light absorption is achieved through careful bandgap engineering, allowing the quantum dots to absorb different wavelengths of sunlight. The diverse composition of ternary/quaternary quantum dots contributes to improved charge separation and reduced recombination losses, fundamental factors in maximizing the efficiency of energy conversion. The advanced materials not only facilitate efficient electron injection into the semiconductor layer but also offer versatility in tailoring the optoelectronic properties of the solar cell. The multi-dot structure enhances light harvesting capabilities, increasing the likelihood of capturing photons across a wide range of the solar spectrum. This approach addresses limitations observed in traditional solar cells and holds promise for boosting overall performance in harnessing solar energy. The potential for multiple exciton generation within ternary/quaternary quantum dot systems adds an intriguing dimension to their functionality, offering the possibility of generating multiple electron-hole pairs from a single absorbed photon. This phenomenon has the potential to significantly enhance the quantum efficiency of the solar cell.

Well Integrity for Abandoned Well Re-entries addresses well integrity and operational risks that accompany the benefits of using an old and abandoned wellbore by providing it a second chance to perform. Re-entering an abandoned well provides new life to an old wellbore by reducing the need for drilling new wells. This, in turn, reduces emissions footprint, drilling waste, and costs for some wells. The book covers well integrity basics, abandoned wells, analysis required for re-entry, potential uses for re-entered wells (including applications for EOR, CO2 EOR with sequestration, natural gas storage, geothermal heat recovery, and much more.) Packed with case studies and tips for practical application, this book provides readers with an understanding of re-entry techniques, pitfalls, and diagnostics to determine well integrity. This novel text digs deep into the process and benefits of re-entering abandoned wells in support of sustainability.

This book aims to work out the distributed economic operation in smart grids in a systematic way, which ranges from model-based to model-free perspectives. The main contributions of this book can be summarized into three folds. First, we investigate the fundamental economic operation problems in smart grids from model-based perspective. Specifically, these problems can be modeled as deterministic optimization models, and we propose some distributed optimization algorithms by integrating the multi-agent consensus theory and optimization techniques to achieve the distributed coordination of various generation units and loads. Second, due to the randomness of the large-scale renewable energies and the flexibility of the loads, we further address these economic operation problems from a model-free perspective, and we propose learning-based approaches to address the uncertainty and randomness. At last, we extend the idea of model-based and model-free algorithms to plug-in electric vehicles (PEVs) charging/discharging scheduling problem, the key challenge of which involves multiple objectives simultaneously while the behavior of PEVs and the electricity price are intrinsically random. This book presents several recent theoretical findings on distributed economic operation in smart grids from model-based and model-free perspectives. By systematically integrating novel ideas, fresh insights, and rigorous results, this book provides a base for further theoretical research on distributed economic operation in smart grids. It can be a reference for graduates and researchers to study the operation and management in smart grids. Some prerequisites for reading this book include optimization theory, matrix theory, game theory, reinforcement learning, etc.
