Book Description
As the global community confronts challenges in energy, environment, health, agriculture, industry, and construction, the significance of sustainable materials becomes paramount. The looming specter of resource depletion necessitates a paradigm shift, urging researchers and engineers to anticipate future needs and forge materials that align with evolving requirements. Next Generation Materials for Sustainable Engineering underscores the urgency of conserving resources and provides a blueprint for achieving this through judicious and sustainable use. From polymers to alloys, nanocomposites to biomaterials, this book traverses the expansive landscape of materials, deciphering their structures and properties with an eye toward sustainability. The relentless pursuit of innovation in synthesis protocols takes center stage, unveiling pathways to creating novel materials. The chapters dedicated to specific material applications, such as spintronics, nanowires, phase change materials, and nanocomposites, offer a detailed panorama of the latest advancements. This book bridges the gap between theoretical understanding and practical applications by exploring materials for renewable energy, electronic devices, artificial photosynthesis, lithium-sulfur batteries, supercapacitors, and biomedical applications. The book serves as a beacon for academicians, researchers, and material scientists, guiding them through state-of-the-art developments, emerging trends, and challenges in material science and engineering.

Book Description
One of several challenges that wave energy technologies face is their inability to generate electricity cost-competitively with other grid-scale energy generation sources. Several studies have identified two approaches to lower the levelised cost of electricity: reduce the cost over the device's lifetime or increase its overall electrical energy production. Several advanced control strategies have been developed to address the latter. However, only a few take into account the overall efficiency of the power take-off (PTO) system, and none of them solve the optimisation problem that arises at each sampling time on real-time. In this paper, a detailed Nonlinear model predictive control (NMPC) approach based on the real-time iteration (RTI) scheme is presented, and the controller performance is evaluated using a time-domain hydrodynamics model (WEC-Sim). The proposed control law incorporates the PTO system's efficiency in a control law to maximise the energy extracted. The study also revealed that RTI-NMPC clearly outperforms a simple resistive controller.

Book Description
This book presents computationally efficient MPC solutions. The classical model predictive control (MPC) approach to control dynamical systems described by the Wiener model uses an inverse static block to cancel the influence of process nonlinearity. Unfortunately, the model's structure is limited, and it gives poor control quality in the case of an imperfect model and disturbances. An alternative is to use the computationally demanding MPC scheme with on-line nonlinear optimisation repeated at each sampling instant. A linear approximation of the Wiener model or the predicted trajectory is found on-line. As a result, quadratic optimisation tasks are obtained. Furthermore, parameterisation using Laguerre functions is possible to reduce the number of decision variables. Simulation results for ten benchmark processes show that the discussed MPC algorithms lead to excellent control quality. For a neutralisation reactor and a fuel cell, essential advantages of neural Wiener models are demonstrated.

Book Description
Waves in Oceanic and Coastal Waters describes the observation, analysis and prediction of wind-generated waves in the open ocean, in shelf seas, and in coastal regions with islands, channels, tidal flats and inlets, estuaries, fjords and lagoons. Most of this richly illustrated book is devoted to the physical aspects of waves. After introducing observation techniques for waves, both at sea and from space, the book defines the parameters that characterise waves. Using basic statistical and physical concepts, the author discusses the prediction of waves in oceanic and coastal waters, first in terms of generalised observations, and then in terms of the more theoretical framework of the spectral energy balance. He gives the results of established theories and also the direction in which research is developing. The book ends with a description of SWAN (Simulating Waves Nearshore), the preferred computer model of the engineering community for predicting waves in coastal waters.
