Desert Weeds: Personal Narrative on Botanical First Responders

by Garry Rogers

In their rapid colonization of soil exposed by fires, floods, and grazing animals, weeds resemble the human specialists we label Emergency Medical Technicians (EMTs). Weeds are the first responders when disasters occur in nature. They occupy bare soil and prevent erosion by wind and water. In extreme cases such as a landslide, weeds are essential to the healing processes that replace the lost soil. Like a Band-Aid on a skinned knee, weeds protect the land while it recovers. Besides protecting the soil after disaster, weeds provide food for wildlife, and some of them provide food and medicine for people. Able to withstand harsh conditions, weeds will proliferate as global warming and other human impacts intensify. Thus, nature’s EMTs will increase while all other plants decline. The book provides a succinct definition of weeds according to their form and function in ecosystem processes. The narrative uses a representative set of weed species from a desert location to illustrate the full range of weed characteristics.

Desiccant-Assisted Cooling

by Carlos Eduardo Leme Nóbrega Nisio Carvalho Lobo Brum

The increasing concern with indoor air quality has led to air-quality standards with increased ventilation rates. Although increasing the volume flow rate of outside air is advisable from the perspective of air-quality, it is detrimental to energy consumption, since the outside air has to be brought to the comfort condition before it is insufflated to the conditioned ambient. Moreover, the humidity load carried within outside air has challenging HVAC engineers to design cooling units which are able to satisfactorily handle both sensible and latent contributions to the thermal load. This constitutes a favorable scenario for the use of solid desiccants to assist the cooling units. In fact, desiccant wheels have been increasingly applied by HVAC designers, allowing distinct processes for the air cooling and dehumidification. In fact, the ability of solid desiccants in moisture removal is effective enough to allow the use of evaporative coolers, in opposition to the traditional vapor-compression cycle, resulting in an ecologically sound system which uses only water as the refrigerant. Desiccant Assisted Cooling: Fundamentals and Applications presents different approaches to the mathematical modeling and simulation of desiccant wheels, as well as applications in thermal comfort and humidity controlled environments. Experts in the field discuss topics from enthalpy, lumped models for heat and mass transfer, and desiccant assisted radiant cooling systems, among others. Aimed at air-conditioning engineers and thermal engineering researchers, this book can also be used by graduate level students and lecturers in the field.

Design Added Value: How Design Increases Value for Architects and Engineers

by Ömer Akın

Design has intrinsic, economic value. To make this value tangible, design features of buildings need to be explored, measured, and taken into account when initiating projects and financing their construction. It is as calculable as the extrinsic value of a project. However, we need concepts, strategies, methods, techniques, and tools to do just that. The Value Based Design approach and Design-Added Value (D-AV) methodology in this book enables architects, engineers, contractors and owner-clients of buildings to benefit from extraordinary design and construction features. It explains the rationale and motivation for D-AV methodology, outlines and illustrates this methodology with examples, provides complete and detailed examples of how the key analysis techniques work through historical case studies, and describes specific methods used in application of the D-AV methodology, such as Bayesian statistics, cost benefit analysis, pairwise comparison techniques, cognitive walkthroughs, and optimization.

Design Aids for Stiffened Composite Shells with Cutouts

by Sarmila Sahoo

This book focuses on the free vibrations of graphite-epoxy laminated composite stiffened shells with cutout both in terms of the natural frequencies and mode shapes. The dynamic analysis of shell structures, which may have complex geometry and arbitrary loading and boundary conditions, is solved efficiently by the finite element method, even including cutouts in shells. The results may be readily used by practicing engineers dealing with stiffened composite shells with cutouts. Several shell forms viz. cylindrical shell, hypar shell, conoidal shell, spherical shell, saddle shell, hyperbolic paraboloidal shell and elliptic paraboloidal shell are considered in the book. The dynamic characteristics of stiffened composite shells with cutout are described in terms of the natural frequency and mode shapes. The size of the cutouts and their positions with respect to the shell centre are varied for different edge constraints of cross-ply and angle-ply laminated composite shells. The effects of these parametric variations on the fundamental frequencies and mode shapes are considered in detail. The information regarding the behavior of stiffened shells with cutouts for a wide spectrum of eccentricity and boundary conditions for cross ply and angle ply shells may be used as design aids for structural engineers. The book is a significant contribution to the existing literature from the point of view of both industrial importance and academic interest.

Design Alchemy

by Roderick Sims

The promise of online learning--flexible, learner-centered, responsive--was forward-looking and poised to revolutionize education. But too often online learning courses have little room for student engagement and their design does not reflect the potential for interactive and collaborative learning. Design Alchemy counters this trend by synthesizing the art and science of educational design to model a whole that transcends the sum of its parts. Challenging yet accessible, it clearly sets out steps for harnessing innovative strategies and designer creativity to provide educational platforms that reduce learner boredom and instructor burnout, and encourage deeper interaction with subject matter. Activities, assessment methods, and sample course materials are designed toward improving quality, embracing diversity, and adapting positively to change. And the book's palette of resources enables readers to effectively apply the principles in their own practice: The evolution of Design Alchemy in the context of online learning. Alignment with core theories and practice models. The framework: elements of pedagogy and components of practice. Case studies showing Design Alchemy in real-world learning. Tools, templates, and a sample syllabus. The Design Alchemy Manifesto, summarizing key ideas. Researchers and practitioners in technology and education will look to Design Alchemy as a transformative work to help make the most of student potential, learning opportunities, and their own professional growth.

Design and Analysis of Biomolecular Circuits

by Douglas Densmore Heinz Koeppl Gianluca Setti Mario Di Bernardo

The book deals with engineering aspects of the two emerging and intertwined fields of synthetic and systems biology. Both fields hold promise to revolutionize the way molecular biology research is done, the way today's drug discovery works and the way bio-engineering is done. Both fields stress the importance of building and characterizing small bio-molecular networks in order to synthesize incrementally and understand large complex networks inside living cells. Reminiscent of computer-aided design (CAD) of electronic circuits, abstraction is believed to be the key concept to achieve this goal. It allows hiding the overwhelming complexity of cellular processes by encapsulating network parts into abstract modules. This book provides a unique perspective on how concepts and methods from CAD of electronic circuits can be leveraged to overcome complexity barrier perceived in synthetic and systems biology.
