Complete and comprehensive manual for eliciting, defining, and managing needs and requirements, integration, verification, and validation across the lifecycle The INCOSE Needs and Requirements Manual presents product development and systems engineering practices, activities, and artifacts from the perspective of needs, requirements, verification, and validation across the system lifecycle. Composed of 16 chapters, this book provides practical guidance to help organizations understand the importance of lifecycle concepts, needs, requirements, verification, and validation activities, enabling them to successfully and effectively implement these activities during product development, systems engineering, and project management. The parent handbook published by Wiley, INCOSE Systems Engineering Handbook, divides the system lifecycle into a series of processes, with each process described in terms of a series of activities. This Manual provides more detail needed by practitioners to successfully implement these activities, with guidance and lessons learned from hundreds of years of collective experience of the authors, contributors, and reviewers. For example, while the Handbook mentions the need to define the problem statement, mission, goals, and objectives for a system, the Manual provides detailed guidance on doing so. Sample topics covered in the INCOSE Needs and Requirements Manual include: Defining the problem, opportunity, or threat and defining a mission statement, goals, objectives, and measures.Identifying external and internal stakeholders, eliciting stakeholder needs and requirements, defining drivers and constraints, and assessing risk.Performing lifecycle concept analysis and maturation and defining an integrated set of needs that represents the scope of the project.Transforming the integrated set of needs into well-formed design input requirements.Using attributes to manage needs and requirements across the lifecycle.Continuous integration, verification, and validation across the lifecycle.Moving between levels of the architecture, flow down and allocation of requirements, and budgeting performance, resource, and quality requirements.Defining the system verification and system validation success criteria, method, strategy, and responsible organizations.Planning and executing successful system verification and validation programs.Managing needs, requirements, verification, and validation across the lifecycle.Understanding the importance of an integrated, collaborative project team and effective communication between team members The INCOSE Needs and Requirements Manual is an essential accompanying reference to the INCOSE Systems Engineering Handbook for novice and seasoned system engineers, software engineers, project managers, product developers, tool vendors, course developers, educators, trainers, customers, suppliers, non-SE stakeholders , as well as researchers and students studying systems engineering and systems design.

From one of the world’s leading authorities on animal behavior, the astonishing story of how the brain drives the evolution of beauty in animals and humansIn A Taste for the Beautiful, Michael Ryan, one of the world’s leading authorities on animal behavior, tells the remarkable story of how he and other scientists have taken up where Darwin left off, transforming our understanding of sexual selection and shedding new light on animal and human behavior. Drawing on cutting-edge science, Ryan explores key questions: Why do animals perceive certain traits as beautiful and others not? Do animals have an inherent sexual aesthetic and, if so, where is it rooted? Ryan argues that the answers lie in the brain—particularly of females, who act as biological puppeteers, spurring the development of beautiful traits in males. Vividly written and filled with fascinating stories, A Taste for the Beautiful will change how you think about beauty and attraction in the animal world and beyond.

From one of the world's leading authorities on animal behavior, the astonishing story of how the female brain drives the evolution of beauty in animals and humans Darwin developed the theory of sexual selection to explain why the animal world abounds in stunning beauty, from the brilliant colors of butterflies and fishes to the songs of birds and frogs. He argued that animals have "a taste for the beautiful" that drives their potential mates to evolve features that make them more sexually attractive and reproductively successful. But if Darwin explained why sexual beauty evolved in animals, he struggled to understand how. In A Taste for the Beautiful, Michael Ryan, one of the world's leading authorities on animal behavior, tells the remarkable story of how he and other scientists have taken up where Darwin left off and transformed our understanding of sexual selection, shedding new light on human behavior in the process. Drawing on cutting-edge work in neuroscience and evolutionary biology, as well as his own important studies of the tiny Tungara frog deep in the jungles of Panama, Ryan explores the key questions: Why do animals perceive certain traits as beautiful and others not? Do animals have an inherent sexual aesthetic and, if so, where is it rooted? Ryan argues that the answers to these questions lie in the brain--particularly of females, who act as biological puppeteers, spurring the development of beautiful traits in males. This theory of how sexual beauty evolves explains its astonishing diversity and provides new insights about how much our own perception of beauty resembles that of other animals. Vividly written and filled with fascinating stories, A Taste for the Beautiful will change how you think about beauty and attraction.

In Venezuelan Stick Fighting: The Civilizing Process in Martial Arts, Michael J. Ryan examines the modern and historical role of the secretive tradition of stick fighting within rural Venezuela. Despite profound political and economic changes from the early twentieth century to the modern day, traditional values, practices, and social imaginaries associated with older forms of masculinity and sociality are still valued. Stick, knife, and machete fighting are understood as key means of instilling the values of fortitude and cunning in younger generations. Recommended for scholars of anthropology, social science, gender studies, and Latin American studies.

In the vast majority of patients, hypertension has no identifiable cause. Moreover, despite decades of discovery and therapeutic development, approximately only half of the hypertensive patients are achieving clinically recommended blood pressure control. For these reasons, there has been continued interest in studying the factors that underlie the pathogenesis of hypertension. One area of research that has garnered significant attention is the potential link between immune system activation and blood pressure. Several lines of evidence, dating back several decades, support the concept for this association. This monograph gives a history of the early studies linking immune system function with hypertension and an overview of the large number of studies published in the past decade. The major focus is on the components of the innate and adaptive immune systems for which there is considerable evidence of their contributions to blood pressure control.

Adapting battlefield communications systems to accommodate fast-changing technological developments, while at the same time meeting the operational requirements of a broad range of operational environments, is a major challenge for both civilian and military defense communications engineers. This work examines satellite, cellular, and network solutions to these problems and presents practical techniques for upgrading current systems.

In a Panamanian pond, male tungara frogs (Physalaemus pustulosus) gather in choruses, giving their advertisement call to the females that move among them. If a female chooses to make physical contact with a male, he will clasp her and eventually fertilize her eggs. But in vying for the females, the males whose calls are most attractive may also attract the interest of another creature: the fringe-lipped bat, a frog eater. In the Tungara Frog, the most detailed and informative single study available of frogs and their reproductive behavior, Michael J. Ryan demonstrates the interplay of sexual and natural selection. Using techniques from ethology, behavioral ecology, sensory physiology, physiological ecology, and theoretical population genetics in his research, Ryan shows that large males with low-frequency calls mate most successfully. He examines in detail a number of explanations for the females' preferences, and he considers possible evolutionary forces leading to the males' success. Though certain vocalizations allow males to obtain mates and thus should be favored by sexual selection, this study highlights two important costs of such sexual displays: the frogs expand considerable energy in their mating calls, and they advertise their whereabouts to predators. Ryan considers in detail how predators, especially the frige-lipped bat (Trachops cirrhosus), affect the evolution of the tungara frog's calls.
