This book applies traditional reliability engineering methods to prognostics and health management (PHM), looking at remaining useful life (RUL) and its dynamics, to enable engineers to effectively and accurately predict machinery and systems useful lifespan. One of the key tools used in defining and implementing predictive maintenance policies is the RUL indicator. However, it is essential to account for the uncertainty inherent to the RUL, as otherwise predictive maintenance strategies can be incorrect. This can cause high costs or, alternatively, inappropriate decisions. Methods used to estimate RUL are numerous and diverse and, broadly speaking, fall into three categories: model-based, data-driven, or hybrid, which uses both. The author starts by building on established theory and looks at traditional reliability engineering methods through their relation to PHM requirements and presents the concept of RUL loss rate. Following on from this, the author presents an innovative general method for defining a nonlinear transformation enabling the mean residual life to become a linear function of time.

Solar Thermal Conversion Technologies for Industrial Process Heating presents a comprehensive look at the use of solar thermal energy in industrial applications, such as textiles, chemical processing, and food. The successful projects implemented in a variety of industries are shown in case studies, alongside performance assessment methodologies. The book includes various solar thermal energy conversion technologies and new techniques and applications of solar collectors in industrial sectors. Solar energy is the largest and most widely distributed renewable energy resource on the planet and can be utilized for a wide range of applications, such as solar water heating, photovoltaic electricity generation, solar thermal energy generation, and all manner of passive and active solar architectures. Besides environmental consciousness, the dwindling of traditional energy sources also marks solar energy as the appropriate energy source to meet the increasing energy demand worldwide. Solar thermal collectors can be used effciently to meet the heating needs of industrial processes because many industrial processes in various industries operate at temperatures ranging from 80 °C to 240 °C. Industrial energy analysis shows that solar thermal energy has enormous applications at low (i.e. 20–200 °C), medium, and medium-high (i.e. 80–240 °C) temperature levels. Almost all industrial processes require heat in some parts of their processes.

This book presents the so-called Shuffled Shepherd Optimization Algorithm (SSOA), a recently developed meta-heuristic algorithm by authors. There is always limitations on the resources to be used in the construction. Some of the resources used in the buildings are also detrimental to the environment. For example, the cement utilized in making concrete emits carbon dioxide, which contributes to the global warming. Hence, the engineers should employ resources efficiently and avoid the waste. In the traditional optimal design methods, the number of trials and errors used by the designer is limited, so there is no guarantee that the optimal design can be found for structures. Hence, the deigning method should be changed, and the computational algorithms should be employed in the optimum design problems. The four primary categories of metaheuristic algorithms are evolution-based, physics-based, swarm-based, and human-based, depending on their inspiration. Evolutionary algorithms are inspired by the characteristics of the biological evolution, including crossover, mutation, and selection. Inspiration of swarm intelligence algorithms is based on the social behavior of creatures living in a group, which might be a swarm, herd, or flock. The human-based algorithms consist of optimizers that simulate certain human behaviors. As the fourth class of metaheuristic algorithms, physics-based algorithms are motivated by physical rules.

Due to the structural flexibility, large surface area, tailorable pore size and functional tenability, metal-organic frameworks (MOFs) can lead to materials with unique properties. This book covers the fundamental aspects of MOFs, their synthesis and modification, including their potential applications in different domains. The major focus is on applications including chemical, biosensors, catalysis, drug delivery, supercapacitors, energy storage, magnetics and their future perspectives. Due to the structural flexibility, large surface area, tailorable pore size and functional tenability, metal-organic frameworks (MOFs) have become a fascinating class of materials and are continuing to inspire both scientists and engineers. MOFs are the combination of organic and inorganic structure elements that can lead to materials with unique properties, and the choice of initial building units makes it possible to vary some parameters, such as the pore size, density as well as the specific surface area, which opens up new ways to produce materials with tailored physicochemical properties. This ability to fine-tune MOF properties is evident in various areas, both academic and industrial, with potential practical applications including gas storage and separation, heterogeneous catalysis, chemical sensing, biomedical applications, fabrication of membranes or thin films and many more. Hence, these materials play a key role in life every day and their effect on the future of humanity’s technology. Therefore, exciting developments, new advancements and foundations, direction for further exploring MOFs for their applications and critical analysis of the research are necessary to provide the field’s current status.

Most solar cells currently in commercial use are p-type solar cells, due to their historically lower cost and ease of manufacture compared to n-type solar cells. However, due to improved manufacturing technology and falling cost in general, the cost difference between the two types has shrunk, making n-type solar cells an attractive option for future commercial high-efficiency solar cells. n-type solar cells are less prone to light-induced degradation, and are also less affected by iron impurities. This makes n-type solar cells more efficient compared to their p-type counterparts, with efficiencies of up to 25% being feasible in production. Challenges in the manufacturing process and regarding degradation still remain to be solved, in order to realise n-type solar cells' full potential. The challenges, solutions and opportunities afforded by n-type solar cells are explored in this volume.
