Voice Compression and Communications: Principles and Applications for Fixes and Wireless Channels
No full textUp-to-date, expert coverage of topics in wireless voice communications Voice communication is the most important facet of mobile radio service. Even when the predicted surge of wireless data and Internet services becomes a reality, voice will remain the most natural means of human communication. Voice Compression and Communications details issues in wireless voice communications and treats compression, channel coding, and wireless transmission as a joint subject. Part I covers background material, whereas Part II provides detailed information on both proprietary and standardized analysis-by-synthesis codecs, including the speech codecs of virtually all existing wireline-based and wireless systems. Parts III and IV discuss mainly research-based wideband, audio, as well as very low-rate schemes likely to find their way into future standards. Voice Compression and Communications describes fundamental concepts in a non-mathematical way early in the book for those with only a background knowledge of signal processing and communications. More advanced readers will find detailed discussions of theoretical principles, future concepts, and solutions to various specific wireless voice communications problems
The Archaeology of Pewter Vessels in England 1200-1700: A Study of Form and Usage
Get PDFThe first aim is to study the main types of pewter vessels surviving for the period, and to show how they were suited to their domestic purpose, especially the serving of food, and as eating and drinking implements.
The second aim is to attempt to further investigate the alloy ‘trifle’ by having a sample of typical objects analysed by ICP-OES (Inductively Coupled Plasma Optical Emission Spectrometry). This alloy was introduced by the Pewterers’ Company (WCP) by the 16th century for the purpose of providing an extended range of wares in a more durable metal than ‘lay’ metal, but less expensive than ‘fine’ metal, as specified by the Company.
The third aim is to explore the occupations of the differing types of ‘potter’ who worked within the Company during the second half of the 17th century. The growth of this separate capitalist group of middle men ‘potters’ or retailers of ceramics and glassware has not previously been noted. The differing levels of wealth and work of other, mainstream, Pewterers is explored by comparison.
The majority of the finds came from anaerobic marine rather than traditional land sites and consisted chiefly of medieval to 17th century tablewares – dishes, saucers, plates, porringers, salts, beakers and other smaller drinking vessels, together with a few larger flagons. Such smaller drinking vessels were frequently listed as ‘trifles’ from the early 17th century in the Company records.
Individuals described as potters were sometimes identified amongst the Company’s membership. It was decided to try to determine their actual occupations by further examining the Court Minutes and wills and inventories of likely individuals.
It was found that the various dishes, saucers and platters were component parts of the ‘garnish’ the chief serving vessels used between the 14th to 18th century to serve food to the middling sort of people, and that this played a central role not only as utilitarian wares but as objects of decoration and status as well. The Pewterers’ Company members were highly innovative and also produced the country’s first plate (apart from in silver) by the mid-16th century and which remained in use unaltered until the 1670s. Linear dimensions were correlated with the more usual sizes by weight for the first time from the remains of the garnish on the Mary Rose, lost 1545.
Analysis of a sample of the smaller drinking vessels by Sheffield Assay Office detected an alloy of some 4-6% lead and this was likely to qualify as trifle alloy.
While some individuals did indeed make drinking wares, it was discovered that the term potter usually applied to retailers of glassware and ceramics – a new occupational label. A number of such individuals within the Pewterers’ Company played formative roles in setting up a new Glass Sellers Company in 1664. The business activities of this group – typical of individualist ventures during the 17th century – had not previously been noted by historians of the Company and indicated the Pewterers’ heterogeneous and commercial make up from this time

Singular harmonic maps into hyperbolic spaces and applications to general relativity
No full textHarmonic maps with singular boundary behavior from a Euclidean domain into hyperbolic spaces arise naturally in the study of axially symmetric and stationary spacetimes in general relativity. In particular, the study of multi-black-hole configurations and the force between co-axially rotating black holes requires, as a first step, an analysis on the boundary regularity of the "next order term" of those harmonic maps. We carry out this analysis by considering those harmonic maps as solutions to some homogeneous divergence systems of partial differential equations with singular coefficients. We then apply our result to study the regularity of axially symmetric and stationary electrovac
spacetimes, which extends previous works by Weinstein and by Li and Tian. This dissertation is based on a preprint of the author.Ph.D.Includes bibliographical references (p. 51-52)by Luc L. Nguye
The Moral Demands we Make On Others
No full textWhat allows us to make moral demands on other people? How important are relationships in ethical decision-making and why should people act ethically in the first place? Join WHY?’s host Jack Russell Weinstein and his guest Yale professor Stephen Darwall, as they ask these and your questions during an important exploration into the very foundations of morality.
Stephen Darwall is an influential ethicist whose recent work has captured the imagination of many who are looking for a new way to talk about morality. He is the Andrew Downey Orrick Professor of Philosophy at Yale University and the John Dewey Distinguished University Professor Emeritus at the University of Michigan. He is the author of numerous books including The Second-Person Standpoint and Welfare and Rational Care.
In the course of the discussion, Steve mentions the painting “The Tribute Money” by Bernardo Strozzi. Here is the painting for you to consider:

Spending Health Care Dollars Wisely: Can Cost-Effectiveness Analysis Help? 16th Annual Herbert Lourie Memorial Lecture on Health Policy
Get PDFAre we getting the most health improvement possible for our money. In other words, are all the things that we do in medicine really worth it? That is where cost-effectiveness comes in. As a nation, we have been unwilling, at least publicly, to look explicitly at the value, in terms of improved health outcome, that we get for our health care dollars. With advances in medical technology putting unsustainable pressure on health care costs, our historical reluctance to measure value for health care may have to change. I start this brief by describing cost-effectiveness analysis as a method of determining the value, measured in Quality-Adjusted Life Years, of medical technologies as they are applied to treat, diagnose, or prevent various conditions. Based on this information, I then argue that some highly beneficial, low-cost procedures are significantly underutilized, and that other medical technologies may be overutilized based on the amount of health benefit they yield in relation to their cost. Next, I give examples from current research, my own and that of colleagues, illustrating how cost-effectiveness analysis can be used to guide the use of new diagnostic testing technologies (such as DNA or RNA typing of infectious agents or identification of genomic or proteinomic markers in cancer patients).
