Recently, there has been significant public concern to RF exposure from Smart Meters. Utility companies have even provided Opt-Out options for consumers; however, the question still need to be answered is: Are Smart Meters emitting RF radiation within the prescribed FCC guidelines? Several experimental and simulation studies have been performed by the utility companies, and also supervisory agencies like EPRI, and the CPUC to determine the extent of RF radiation from residential Smart meters. The main goal of this project is to carry out an independent study of RF radiation from residential and workplace Smart Meters, and to compare it with FCC standard, whether it is within the permissible limit or not. The location where this study was performed was at the California State University campus, and also in a residential meter cluster in Folsom. The results give us a better understanding of RF radiation from Smart Meters, and are a valuable tool to planning future Smart meter capabilities such as Home Area Networks (HANs)
Comprehensive, cross-disciplinary coverage of Smart Grid issues from global expert researchers and practitioners. This definitive reference meets the need for a large scale, high quality work reference in Smart Grid engineering which is pivotal in the development of a low-carbon energy infrastructure. Including a total of 83 articles across 3 volumes The Smart Grid Handbook is organized in to 6 sections: Vision and Drivers, Transmission, Distribution, Smart Meters and Customers, Information and Communications Technology, and Socio-Economic Issues. Key features: Written by a team representing smart grid R&D, technology deployment, standards, industry practice, and socio-economic aspects. Vision and Drivers covers the vision, definitions, evolution, and global development of the smart grid as well as new technologies and standards. The Transmission section discusses industry practice, operational experience, standards, cyber security, and grid codes. The Distribution section introduces distribution systems and the system configurations in different countries and different load areas served by the grid.

"The definitive reference for budding and experienced cancer epidemiologists alike." -American Journal of Epidemiology "Practitioners in epidemiology and oncology will find immense value in this." -JAMA Since its initial publication in 1982, CANCER EPIDEMIOLOGY AND PREVENTION has served as the premier reference work for students and professionals working to understand the causes and prevention of cancer in humans. Now revised for the first time in more than a decade, this fourth edition provides a comprehensive summary of the global patterns of cancer incidence and mortality, current understanding of the major causal determinants, and a rationale for preventive interventions. Special attention is paid to molecular epidemiologic approaches that address the wider role of genetic predisposition and gene-environment interactions in cancer etiology and pathogenesis. New and timely chapters on environmental and social-epidemiologic factors include: - The role of social class disparities - The role of obesity and physical inactivity - The potential effects of electromagnetic fields and radiofrequency radiation - The principles of cancer chemoprevention For both seasoned professionals and newer generations of students and researchers, this fourth edition of CANCER EPIDEMIOLOGY AND PREVENTION remains the authority in the field -- a work of distinction that every lab, library, student, professional, or researcher should have close at hand.
"Detection of super-regenerative receivers using their unintended electromagnetic emissions at a significant distance is challenging due to high levels of ambient noise. The evolution of an approach used to solve this problem is chronicled within the three papers that combine to form this dissertation. First, a passive detection method was created for detecting devices based on the characterization of their unintended emissions and utilized a cascading correlation method to confirm detection. Using a simple sine-wave stimulation to modify these unintended emissions produced better results over passive detection techniques by improving the signal quality and the consistency of the unintended emissions, but was still rather limited in extending the reliable detection distance. Additionally, extensive characterization measurements of the target device were required. If the response of the receiver to a stimulation is known, however, a more complex stimulation can be used to embed additional information into the unintended emissions which does not require the previously essential characterization data. For regenerative receivers, an amplitude modulated stimulation generates a corresponding modulation in the unintended emissions of the target device. The receiver may thus be detected from these modulated emissions by calculating the received signal energy and then correlating it with the amplitude of the stimulation. A high correlation indicates the presence of the device. The receiver may be detected even when its emissions are well below the noise floor. Results show that five super-regenerative receivers from three different manufacturers can be detected in a noisy environment to distances of over 100 meters with an area under the receiver operating characteristic (ROC) curve of 94%"--Abstract, leaf iv
