While engineers played a critical role in the performance of both the Union and Confederate armies during the Civil War, few historians have examined their experiences or impact. Larry J. Daniel's Engineering in the Confederate Heartland fills a gap in that historiography by analyzing the accomplishments of these individuals working for the Confederacy in the vast region between the Appalachian Mountains and the Mississippi River, commonly referred to as the Western Theater. Though few in number, the members of the western engineer corps were vital in implementing Confederate strategy and tactics. Most Confederate engineers possessed little to no military training, transitioning from the civilian tasks of water drainage, railroad construction, and land surveys to overseeing highly technical war-related projects. Their goal was simple in mission but complex in implementation: utilize their specialized skills to defeat, or at least slow, the Union juggernaut. The geographical diversity of the Heartland further complicated their charge. The expansive area featured elevations reaching over six thousand feet, sandstone bluffs cut by running valleys on the Cumberland Plateau, the Nashville basin's thick cedar glades and rolling farmland, and the wind-blown silt soil of the Loess Plains of the Mississippi Valley. Regardless of the topography, engineers encountered persistent flooding in all sectors. Daniel's study challenges the long-held thesis that the area lacked adept professionals. Engineers' expertise and labor, especially in the construction of small bridges and the laying of pontoons, often proved pivotal. Lacking sophisticated equipment and technical instruments, they nonetheless achieved numerous successes: the Union army never breached the defenses at Vicksburg or Atlanta, and by late 1864, the Army of Tennessee boasted a pontoon train sufficient to span the Tennessee River. Daniel uncovers these and other essential contributions to the war effort made by the Confederacy's western engineers.

Humanitarian engineering is to provide disadvantaged individuals and communities with engineering solutions that improve lives and livelihoods. The provision of water, energy, food, shelter, energy and information are some of the issues targeted by this "discipline". Humanitarian Engineers could be the key towards achieving the Sustainable Development Goals. Currently, UNESCO is working to strengthen engineering education through curricula development and capacity building. It is also incorporating sustainability topics into engineering education by highlighting the need for green technology in engineering applications. The careful use of resources in a way that does not compromise the environment or deplete the materials for future generations is called sustainable engineering. Both sustainable engineering and humanitarian engineering require a highly interdisciplinary approach since they aim to improve the quality of life for all. The current book looks for the most recent challenges and approaches in the field of humanitarian engineering. A wide variety of topics that fall under the domain are technology-based solutions that tackle humanitarian problems. Pandemics, ageing of population, climate change, social inclusion, extreme poverty and hunger, maternal health and child mortality, education for all, are some indicative topics that could be addressed by technology. Early warning and alerting mechanisms for physical disasters, green engineering approaches, mobile health solutions for remote and underserved populations, are some paradigms that fall under the researched theme. The book is accepting research, real-life case studies, innovative models and approaches, and other work that lies in the presented theme. The proposed collection of chapters will provide an overview of the present thinking and state-of-the-art developments in humanitarian engineering. The book aims at providing latest research findings and their practical implementations, as well as new formulations, solutions, and case studies for tackling humanitarian contemporary issues. The book will give a unique opportunity to stakeholders, researchers and the academic community working in the aforementioned domains to understand the implications and solutions to a variety of topics. The book is anticipated to trigger further research on issues directly related to the proposed humanitarian topics.

Recent Trends in Computer-aided Diagnostic Systems for Skin Diseases: Theory, Implementation, and Analysis provides comprehensive coverage on the development of computer-aided diagnostic (CAD) systems employing image processing and machine learning tools for improved, uniform evaluation and diagnosis (avoiding subjective judgment) of skin disorders. The methods and tools are described in a general way so that these tools can be applied not only for skin diseases but also for a wide range of analogous problems in the domain of biomedical systems. Moreover, quantification of clinically relevant information that can associate the findings of physicians/experts is the most challenging task of any CAD system. This book gives all the details in a step-by-step form for different modules so that the readers can develop each of the modules like preprocessing, feature extraction/learning, disease classification, as well as an entire expert diagnosis system themselves for their own applications.
