Book Description
Aging population and the thereby ever-rising cost of health services call for novel and innovative solutions for providing medical care and services. So far, medical care is primarily provided in the form of time-consuming in-person appointments with trained personnel and expensive, stationary instrumentation equipment. As for many current and past challenges, the advances in microelectronics are a crucial enabler and offer a plethora of opportunities. With key building blocks such as sensing, processing, and communication systems and circuits getting smaller, cheaper, and more energy-efficient, personal and wearable or even implantable point-of-care devices with medicalgrade instrumentation capabilities become feasible. Device size and battery lifetime are paramount for the realization of such devices. Besides integrating the required functionality into as few individual microelectronic components as possible, the energy efficiency of such is crucial to reduce battery size, usually being the dominant contributor to overall device size. In this thesis, we present two major contributions to achieve the discussed goals in the context of miniaturized medical instrumentation: First, we present a synchronization solution for embedded, parallel near-threshold computing (NTC), a promising concept for enabling the required processing capabilities with an energy efficiency that is suitable for highly mobile devices with very limited battery capacity. Our proposed solution aims at increasing energy efficiency and performance for parallel NTC clusters by maximizing the effective utilization of the available cores under parallel workloads. We describe a hardware unit that enables fine-grain parallelization by greatly optimizing and accelerating core-to-core synchronization and communication and analyze the impact of those mechanisms on the overall performance and energy efficiency of an eight-core cluster. With a range of digital signal processing (DSP) applications typical for the targeted systems, the proposed hardware unit improves performance by up to 92% and 23% on average and energy efficiency by up to 98% and 39% on average. In the second part, we present a MCU processing and control subsystem (MPCS) for the integration into VivoSoC, a highly versatile single-chip solution for mobile medical instrumentation. In addition to the MPCS, it includes a multitude of analog front-ends (AFEs) and a multi-channel power management IC (PMIC) for voltage conversion. ...

Book Description
In his seminal Turing Award Lecture, Backus discussed the issues stemming from the word-at-a-time style of programming inherited from the von Neumann computer. More than forty years later, computer architects must be creative to amortize the von Neumann Bottleneck (VNB) associated with fetching and decoding instructions which only keep the datapath busy for a very short period of time. In particular, vector processors promise to be one of the most efficient architectures to tackle the VNB, by amortizing the energy overhead of instruction fetching and decoding over several chunks of data. This work explores vector processing as an option to build small and efficient processing elements for large-scale clusters of cores sharing access to tightly-coupled L1 memory

Book Description
The energy consumption issue in distributed computing systems raises various monetary, environmental and system performance concerns. Electricity consumption in the US doubled from 2000 to 2005. From a financial and environmental standpoint, reducing the consumption of electricity is important, yet these reforms must not lead to performance degradation of the computing systems. These contradicting constraints create a suite of complex problems that need to be resolved in order to lead to 'greener' distributed computing systems. This book brings together a group of outstanding researchers that investigate the different facets of green and energy efficient distributed computing. Key features: One of the first books of its kind Features latest research findings on emerging topics by well-known scientists Valuable research for grad students, postdocs, and researchers Research will greatly feed into other technologies and application domains

Book Description
Despite meter's recasting as a rigid metronome, diverse modern poet-critics refused the formal ideologies of free verse through complex engagements with traditional versification. In the twentieth century, meter became an object of disdain, reimagined as an automated metronome to be transcended by new rhythmic practices of free verse. Yet meter remained in the archives, poems, letters, and pedagogy of modern poets and critics. In Modernism's Metronome, Ben Glaser revisits early twentieth-century poetics to uncover a wide range of metrical practice and theory, upending our inherited story about the "breaking" of meter and rise of free verse.

Book Description
James Weldon Johnson (1871–1938) exemplified the ideal of the American public intellectual as a writer, educator, songwriter, diplomat, key figure of the Harlem Renaissance, and first African American executive of the NAACP. Originally published anonymously in 1912, Johnson’s novel The Autobiography of an Ex-Colored Man is considered one of the foundational works of twentieth-century African American literature, and its themes and forms have been taken up by other writers, from Ralph Ellison to Teju Cole. Johnson’s novel provocatively engages with political and cultural strains still prevalent in American discourse today, and it remains in print over a century after its initial publication. New Perspectives contains fresh essays that analyze the book’s reverberations, the contexts within which it was created and received, the aesthetic and intellectual developments of its author, and its continuing influence on American literature and global culture.

Book Description
This book shows how rhythm constitutes an untapped resource for understanding poetry. Intervening in recent debates over formalism, historicism, and poetics, the authors show how rhythm is at once a defamiliarizing aesthetic force and an unstable concept. Distinct from the related terms to which it’s often assimilated—scansion, prosody, meter—rhythm makes legible a range of ways poetry affects us that cannot be parsed through the traditional resources of poetic theory. Rhythm has rich but also problematic roots in still-lingering nineteenth-century notions of primitive, oral, communal, and sometimes racialized poetics. But there are reasons to understand and even embrace its seductions, including its resistance to lyrical voice and even identity. Through exploration of rhythm’s genealogies and present critical debates, the essays consistently warn against taking rhythm to be a given form offering ready-made resources for interpretation. Pressing beyond poetry handbooks’ isolated descriptions of technique or inductive declarations of what rhythm “is,” the essays ask what it means to think rhythm. Rhythm, the contributors show, happens relative to the body, on the one hand, and to language, on the other—two categories that are distinct from the literary, the mode through which poetics has tended to be analyzed. Beyond articulating what rhythm does to poetry, the contributors undertake a genealogical and theoretical analysis of how rhythm as a human experience has come to be articulated through poetry and poetics. The resulting work helps us better understand poetry both on its own terms and in its continuities with other experiences and other arts.
