The life and works of James Miller, 1704-1744, with particular reference to the satiric content of his poetry and plays.
No full textPhDJames Miller was born the son of a Dorset rector in 1704. He
was himself ordained, but acquired no benefice until just before his
early death, probably because of a scathing portrayal of the Bishop
of London in one of his verse satires. At Oxford he wrote a vivacious
comedy of humours, set in the University. Its production in 1730
began his dramatic career, at a time when the number of London
theatres had just doubled, and new dramatic forms were being invented.
In 1731 his poem Harlequin-Horace, a witty inversion of
the Ars Poetica, attacked pantomime and opera, but also painted a
lively portrait of the entire theatrical world, in the tradition of
the Dunciad.
After collaborating in a translation of Moliere's works Miller
wrote two plays based on this author. Of all his dramatic works
these were the most successful with his contemporaries, and were
followed by a modernisation of Much Ado, and a ballad-opera adapted
from an afterpiece by Jean-Baptiste Rousseau, and rendered highly
topical. Miller made similar use of a recent French comedy showing
a Red Indian's reactions to civilisation, a satiric "fable" by Walsh
and Voltaire's Mahomet. A large quantity of original material was
incorporated into most of these, and this is generally satirical in
nature. The Indian is made to voice almost egalitarian sentiments.
An afterpiece, "The Camp Visitants", satirised military inaction
in the war, and was apparently banned. The manuscripts of the six
plays produced after the Licensing Act bear the examiner's deletions,
and illustrate the nature of the censorship at this time.
Miller's greatest strength is probably his flexible, vigorously
colloquial dialogue. His political satire is mostly contained in
the poetry, which attacks Walpole's administration with increasing
vehemence through the seventeen-thirties, until its fall. In 1740
two poems that used Pope in symbolic contrast to Walpole caused a
sensation. In both poetry and plays Miller is also a social satirist,
who lays unusually strong emphasis on false taste and the deterioration
of culture

No full textVoice 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
Wave energy resource assessment
No full textThe use of satellite altimeter data for spatial mapping of the wave resource is examined.A new algorithm for estimating wave period from altimeter data is developed andvalidated, which enables estimates of wave energy converter (WEC) power to bederived. Maps of the long-term mean WEC power from altimeter data are of a higherspatial resolution than is available from global wave model data. They can be used foridentifying promising wave energy locations along particular stretches of coastline,before a detailed study using nearshore models is undertaken.The accuracy of estimates of WEC power from wave model data is considered. Withoutcalibration estimates of the mean WEC power from model data can be biased of theorder of 10-20%. The calibration of wave model data is complicated by non-lineardependence of model parameters on multiple factors, and seasonal and interannualchanges in biases. After calibration the accuracy in the estimate of the historic powerproduction at a site is of the order of 5%, but the changing biases make it difficult tospecify the accuracy more precisely.The accuracy of predictions of the future energy yield from a WEC is limited by theaccuracy of the historic data and the variability in the resource. The variability in 5, 10and 20 year mean power levels is studied for an area in the north of Scotland, andshown to be greater than if annual power anomalies were uncorrelated noise. Thesensitivity of WEC power production to climate change is also examined, and it isshown that the change in wave climate over the life time of a wave farm is likely to besmall in comparison to the natural level of variability. It is shown that despite theuncertainty related to variability in the wave climate, improvements in the accuracy ofhistoric data will improve the accuracy of predictions of future WEC yield.The topic of extreme wave analysis is also considered. A comparison of estimators forthe generalised Pareto distribution (GPD) is presented. It is recommended that theLikelihood-Moment estimator should be used in preference to other estimators for theGPD. The use of seasonal models for extremes is also considered. In contrast toassertions made in previous studies, it is demonstrated that non-seasonal models have alower bias and variance than models which analyse the data in separate seasons
Optimizing green space locations to reduce daytime and nighttime urban heat island effects in Phoenix, Arizona
No full textabstract: The urban heat island effect is especially significant in semi-arid climates, generating a myriad of problems for large urban areas. Green space can mitigate warming, providing cooling benefits important to reducing energy consumption and improving human health. The arrangement of green space to reap the full potential of cooling benefits is a challenge, especially considering the diurnal variations of urban heat island effects. Surprisingly, methods that support the strategic placement of green space in the context of urban heat island are lacking. Integrating geographic information systems, remote sensing, spatial statistics and spatial optimization, we developed a framework to identify the best locations and configuration of new green space with respect to cooling benefits. The developed multi-objective model is applied to evaluate the diurnal cooling trade-offs in Phoenix, Arizona. As a result of optimal green space placement, significant cooling potentials can be achieved. A reduction of land surface temperature of approximately 1–2 °C locally and 0.5 °C regionally can be achieved by the addition of new green space. 96% of potential day and night cooling benefits can be achieved through simultaneous consideration. The results also demonstrate that clustered green space enhances local cooling because of the agglomeration effect; whereas, dispersed patterns lead to greater overall regional cooling. The optimization based framework can effectively inform planning decisions with regard to green space allocation to best ameliorate excessive heat.Corresponding Author:

Toward seamless networking in indoor environments in millimeter wave bands
No full textThis thesis investigates the possibility of applying the 60GHz band to the indoor networking environment at the systemand link control levels. The work presented in this thesis aims at developing novel systemconcepts for seamless and cost-effective broadband local area networks operating in the 60GHz band in particular andmillimeter-wave bands in general. Different from many efforts today targeting point-to-point cable replacement solutions, this thesis attempts to apply the 60 GHz band to a broader context, i.e., the local area network environment in which multiple users and multiple applications share the network resource simultaneously. The utilization of this millimeter wave band, however, leads to smaller radio cell coverage due to propagation losses and line-of-sight requirements. Indoor networks operating at this band will comprise a large number of pico-cells corresponding to that many of antenna stations. As a result, the cost of many antenna stations has become a major contributor for the total cost of the networks infrastructure. To reduce the systems cost, it is therefore crucial that the complexity of an antenna station is simplified.Radio over fiber (RoF) techniques can be employed to achieve this goal. Particularly, this thesis is based on a RoF technique called Optical Frequency Multiplication (OFM) that is able to generate pure millimeter wave carriers remotely. Instead of placing all the signal processing functions in antenna stations, it is now possible to concentrate those complex functions in a single processing block, i.e., the central station (CS). since the propagation of 60 GHz signals is highly obstructed by objects, it is generally difficult to obtain good signal coverage in the indoor environment. In this thesis, we propose the novel Extended Cell concept that is able to overcome the problem of insufficient signal coverage. In this solution, a number of adjacent radio cells are grouped into an extended cell. Furthermore, all the antenna stations in an extended cell are set to operate in the same radio channel. By controlling the cells to be included into an extended cell, overlap areas between extended cells can be created in transitional areas in the floor to ensure seamless handovers of ongoing connections. To optimize the performance of the system with regards to variable realtime traffic patterns, we propose an algorithm to dynamically form extended cells based on the actual traffic under each cell. The performance of twoMediumAccess Control protocols, i.e., IEEE 802.11 representing the distributed protocol family and IEEE 802.16 representing the centralized protocol one, when applied to the proposed RoF and extended cell based architecture is also discussed in this thesis. A major effect when an optical distribution system is inserted in a traditional wireless network is the additional propagation delay introduced by the fiber links. This additional propagation delay can exceed the timing boundary of the MAC protocols and eventually stop them from working. Another problem also arises when the utilization of the 60 GHz band is combined with the extended cell concept. Specifically, mobile stations in a room will be completely hidden to other stations in other rooms.We show that the throughput of both protocols degrades when the length of optical distribution network increases, but this degradation is not significant.With regards to the hidden terminal problem, the performance of distributed and carried sense based protocols is severely affected. Finally, this thesis concerns the issues of maintaining quality of services (QoS) when the MAC protocols are applied to the proposed network architecture. We have shown that the proposed architecture does not affect the service differentiation mechanisms of the MAC protocols. Moreover, in this architecture, since the central station has the full control of the network, QoS and mobility control algorithms can also be greatly simplified to improve the performance of the network.Electrical Engineering, Mathematics and Computer Scienc
