Data centers consume roughly 1% of the total electricity demand, while ICT as a whole consumes around 10%. Demand is growing exponentially and, left unchecked, will grow to an estimated increase of 20% or more by 2030. This book covers the energy consumption and minimization of the different data center components when running real workloads, taking into account the types of instructions executed by the servers. It presents the different air- and liquid-cooled technologies for servers and data centers with some real examples, including waste heat reuse through adsorption chillers, as well as the hardware and software used to measure, model and control energy. It computes and compares the Power Usage Effectiveness and the Total Cost of Ownership of new and existing data centers with different cooling designs, including free cooling and waste heat reuse leading to the Energy Reuse Effectiveness. The book concludes by demonstrating how a well-designed data center reusing waste heat to produce chilled water can reduce energy consumption by roughly 50%, and how renewable energy can be used to create net-zero energy data centers.
With the rapid advances in technology, the conventional academic and research departments of Electronics engineering, Electrical Engineering, Computer Science, Instrumentation Engineering over the globe are forced to come together and update their curriculum with few common interdisciplinary courses in order to come out with the engineers and researchers with muli-dimensional capabilities. The gr- ing perception of the ‘Hardware becoming Soft’ and ‘Software becoming Hard’ with the emergence of the FPGAs has made its impact on both the hardware and software professionals to change their mindset of working in narrow domains. An interdisciplinary field where ‘Hardware meets the Software’ for undertaking se- ingly unfeasible tasks is System on Chip (SoC) which has become the basic pl- form of modern electronic appliances. If it wasn’t for SoCs, we wouldn’t be driving our car with foresight of the traffic congestion before hand using GPS. Without the omnipresence of the SoCs in our every walks of life, the society is wouldn’t have evidenced the rich benefits of the convergence of the technologies such as audio, video, mobile, IPTV just to name a few. The growing expectations of the consumers have placed the field of SoC design at the heart of at variance trends. On one hand there are challenges owing to design complexities with the emergence of the new processors, RTOS, software protocol stacks, buses, while the brutal forces of deep submicron effects such as crosstalk, electromigration, timing closures are challe- ing the design metrics.
This book introduces a sociological understanding of the emergence of modernity in India and its ramifications on society, economy, and polity. It outlines the main features and context of modernity, as described in classical and later texts of modernity. The essays examine the transformation of Indian society as a consequence of the British colonial encounter resulting in social, economic, and political interventions. It also delineates the Indian context by defining the term community, and its close association with caste and religion, and subsequently examines the challenges in building a pan-Indian or national consciousness with a sense of ‘we-ness’ or common identity. Most importantly, the book also studies the politics of government formation after independence, and the role of dominant castes and classes in gaining power at the Centre. The book concludes with an outline of the definitions and historical practices of social exclusion in India, their contemporary configurations, the image of a socially, economically, and politically exclusive Indian modernity that poses challenges to the Indian state and civil society on account of the exclusion of multiple groups. This book would be useful to the students, researchers and teachers of sociology, women and gender studies, history, economics, political science, and other interdisciplinary courses in social sciences. The book will also be valuable reading for those interested in South Asian studies, especially post-colonial contemporary Indian society.
Preterm neonates remain at increased risk for adverse bilirubin-related outcomes, including acute bilirubin encephalopathy relative to term infants. Yet, most vulnerable neonates are likely to benefit from the potent anti-oxidant properties of bilirubin. Evidence-based guidelines for the management of hyperbilirubinemia in preterm infants, however, are lacking. High concentrations of unconjugated bilirubin can cause permanent neurologic damage in infants, evident through magnetic resonance imaging of chronic bilirubin encephalopathy or kernicterus. There is a growing concern that exposures to even moderate concentrations of bilirubin may lead to subtle but permanent neurodevelopmental impairment referred to as bilirubin-induced neurologic dysfunction. Our current use of phototherapy to decrease bilirubin loads and its potential photo-oxidant properties is a biological conundrum that has been questioned in the use of phototherapy for very low birth weight neonates. In this issue of Clinics in Perinatology, we provide updates on the current understanding of the biology, mechanisms of increasing bilirubin load due to hemolysis, decreased bilirubin binding capacity and glucose-6-phosphate dehydrogenase deficiency, as well as clinical strategies to operationalize the thresholds for hyperbilirubinemia interventions in preterm infants.
Yao and Artusio's Anesthesiology is one of the core texts for anesthesiology residents, and is frequently used as a primary study aid for the ABA oral boards. Each chapter is based on a case history and questions that address disease knowledge and differential diagnosis, progressing through preoperative evaluation, intraoperative management, and postoperative care. The discussion of each question is followed by a short list of the most important references on that topic. The new edition is in full color, and the interior has been redesigned to make it easier to read. There is a new section on pediatric anesthesia. All major areas of anesthesiology are covered.
This book develops a model to examine the language of humour, which is multimodal and accounts for the possibility of transmutation of humour as it is performed through editorial cartoons. By transmutation is meant the transition in the language of humour when it crosses its own boundaries to provoke unprecedented reactions resulting in offensiveness, disappointment or hurt sentiment. The transmutability about the language of humour points to its inherently diabolical nature which manifests in the performance of controversial cartoons. The model is built by borrowing theoretical cues from Roman Jakobson, Roland Barthes, George Lakoff and Mark Johnson. The integrated model, then, is developed to examine the cartoons which were recommended for deletion by the Thorat Committee, following a cartoon controversy in India. Through the cartoon analysis, the model discerns the significance of context and temporality in determining the impact of humour. It also examines how the ethics of humour; the blurred lines of political correctness and incorrectness are dictated by the political atmosphere and the power dynamics.
