Compliance or Defiance?: Assessing the Implementation of Policy Prescriptions for Commercialization by Water Operators (IHE Delft PhD Thesis Series)
by Mireia TutusausWhereas the global water community may have reached consensus on the need for water providers to operate on the basis of commercial principles, staff of water utilities are faced with the challenge of implementing these principles in their everyday work. In the everyday domain, these principles appear to directly conflict with the mandate of water operators to provide water services to all. Moreover, the socio-political, economic and bio-physical context in which these water operate may be ill-suited to implement commercialization. In pursuing commercialization these operators adapt, reinterpret, modify, deflect, alter or betray the original principles of commercialization during implementation. This research takes inspiration from the rich literature on policy implementation and policy translation, which argues that policy models need to be transformed and modified if they are to be successfully adopted or implemented. This research analyzes the alterations visible in the daily implementation of commercial models of water provisioning and, in doing so, present a better understanding of how water operators implement policy prescriptions of commercialization in practice. Based on the analysis of the adaptations and (re)interpretations of the implemented model of commercialization in the different cases, this thesis argues that a new way of speaking about commercialization should be developed.
Compliant Mechanisms: Design of Flexure Hinges
by Nicolae LobontiuWith a rigorous and comprehensive coverage, the second edition of Compliant Mechanisms: Design of Flexure Hinges provides practical answers to the design and analysis of devices that incorporate flexible hinges. Complex-shaped flexible-hinge mechanisms are generated from basic elastic segments by means of a bottom-up compliance (flexibility) approach.

Composing Fisher Kernels from Deep Neural Models: A Practitioner's Approach (SpringerBriefs in Computer Science)
by Tayyaba Azim Sarah AhmedThis book shows machine learning enthusiasts and practitioners how to get the best of both worlds by deriving Fisher kernels from deep learning models. In addition, the book shares insight on how to store and retrieve large-dimensional Fisher vectors using feature selection and compression techniques. Feature selection and feature compression are two of the most popular off-the-shelf methods for reducing data’s high-dimensional memory footprint and thus making it suitable for large-scale visual retrieval and classification. Kernel methods long remained the de facto standard for solving large-scale object classification tasks using low-level features, until the revival of deep models in 2006. Later, they made a comeback with improved Fisher vectors in 2010. However, their supremacy was always challenged by various versions of deep models, now considered to be the state of the art for solving various machine learning and computer vision tasks. Although the two research paradigms differ significantly, the excellent performance of Fisher kernels on the Image Net large-scale object classification dataset has caught the attention of numerous kernel practitioners, and many have drawn parallels between the two frameworks for improving the empirical performance on benchmark classification tasks. Exploring concrete examples on different data sets, the book compares the computational and statistical aspects of different dimensionality reduction approaches and identifies metrics to show which approach is superior to the other for Fisher vector encodings. It also provides references to some of the most useful resources that could provide practitioners and machine learning enthusiasts a quick start for learning and implementing a variety of deep learning models and kernel functions.
Composing Place: Digital Rhetorics for a Mobile World
by Jacob GreeneComposing Place takes an innovative approach to engaging with the compositional affordances of mobile technologies. Mobile, wearable, and spatial computing technologies are more than the latest marketing gimmick from a perpetually proximate future; they are rather an emerging composing platform through which digital writers will increasingly create and distribute place-based multimodal texts. Jacob Greene utilizes and develops a rhetorical framework through which writers can leverage the affordances of these technologies by drawing on theoretical approaches within rhetorical studies, multimodal composition, and spatial theory, as well as emerging “maker” practices within digital humanities and critical media studies, to show how emerging mobile technologies are poised to transform theories, practices, and pedagogies of digital writing. Greene identifies three emerging “modalities” through which mobile technologies are being used by digital writers. First, to counter dominant discourses in contested spaces; second, to historicize entrenched narratives in iconic spaces; and third, to amplify marginalized voices in mundane spaces. Through these modalities, Greene employs Indigenous philosophies and theories that upend the ways that the discipline has centered placed-based rhetorics, offering digital writers better strategies for using mobile media as a platform for civic deliberation, social advocacy, and political action. Composing Place offers close analyses of mobile media experiences created by various artists and digital media practitioners, as well as detailed overviews of Greene’s own projects (also accessible through the companion website: www.composingplace.com). These projects include a digital “countertour” of SeaWorld that demonstrates the ways in which the attraction is driven by capitalism; an augmented reality tour of Detroit’s Woodward Avenue; and a mobile advocacy project in Jacksonville, Florida, that demonstrates the inequitable effects of car-centric public infrastructure. Ultimately, by engaging with these theoretical frameworks, rhetorical design principles, and pedagogical practices of mobile writing, readers can utilize the unique affordances of mobile media in various teaching and research contexts.

Composite Materials Processing Using Microwave Heating Technology (Composites Science and Technology)
by Suchart Siengchin Gaurav Arora Sanjay Mavinkere Rangappa Manoj Kumar Singh Sunny ZafarThis book covers all aspects of composite materials processing and manufacturing using microwave heating technology and their applications in various industrial processes. Depending in the processing and material used, the composites are divided into three major segments: Metal matrix composites (MMCS), ceramics composites (CMCS), and polymer matrix composites (PMCS), respectively. During the manufacturing process of these composite materials, conventional heating technologies are used in which the heat is transferred from the electrical resistance coils to the material via conventional modes of heat transfer. Issues like non-uniform temperature distribution, poor curing efficiency, generation of the in-process scrap, long process cycle, high energy consumption and cost make traditional manufacturing route a difficult choice to select. Recently, microwave-assisted heating has emerged as a promising route for the fabrication of composites as a cost-effective environmentally sustainablemanufacturing process that yields improved mechanical properties which is the main topic of this book. It looks into the mechanism, salient features, and important aspects of microwave heating and their interaction with different composites materials.
