Den här rapporten är en utredning och analys av lämpliga arbetsuppgifter och deras nödvändiga verktyg och hjälpmedel för en skiftledare, Watch Supervisor, vid ett framtida center för fjärrstyrda flygledningstorn, Remote Tower. Ett center för fjärrstyrda flygledningstorn är en centraliserad enhet med uppgiften att flygleda och kontrollera flygsäkerheten på och nära en eller flera flygplatser. Utgångspunkten för datainsamlingen har varit intervjuer med verksamma flygledare och skiftledare på LFV, Sveriges statliga verk för flygtrafiktjänst. Studiebesök har även gjorts vid olika enheter, både flygledartorn och radarkontrollcentraler, däribland Sundsvall RTC som är världens första central för fjärrstyrd flygledning godkänd att sättas i drift. Insamlad data har kompilerats och analyserats och en rekommendation presenteras i slutet av denna rapport angående arbetsuppgifter och verktyg för ovan nämnda skiftledare i ett RTC. Resultatet visar att rollen kommer ha stora likheter med befintliga skiftledarpositioner i den svenska flygledningen.

This dissertation discusses two flute works by Joan Tower (born 1938). The performance medium consists of flute alone, Hexachords for Solo Flute (1972), and flute and orchestra, the Flute Concerto (1989). The discussion on Hexachords consists of a theoretical analysis; discussion on the Flute Concerto pertains to Tower's flute writing through an investigation into her musical language and specific performance techniques. Numerous examples are included to illustrate various aspects of Tower's style. Conclusions follow. The purpose of the paper is, first, to illustrate that basic knowledge of the twelve-tone method can bring a composition out of uncertainty for the performer and allow him to present what is unique within it. Secondly, it is to investigate the stylistic maturation of Joan Tower's flute works. In order to facilitate a better understanding of Tower's music and to provide commentary about the performance of each work, the writer has quoted from personal interviews with the composer and with flutists Carol Wincenc and Patricia Spencer, to whom the works are dedicated.

The Yukon-Tanana terrane (YTT) is a composite arc built on the rifted margin of western North America. The YTT is present in the southeastern part of the St. Cyr area in south-central Yukon, but in the northwest section the structural and lithologic relationships are poorly known. This study describes the structural geometry of the northwest section of the St. Cyr area, west of the Canol Road. The lithological, geochemical, and geochronological characteristics of the Tower Peak unit are investigated in an effort to determine its origin and terrane affinity. In the study area, the Tower Peak unit sits tectonically above a low-grade mafic-ultramafic unit. In turn, this mafic-ultramafic unit is thrust over phyllite and marble creating a composite klippe. Detrital zircons from the marble indicate a maximum depositional age of 368 Ma. This result is consistent with the footwall being part of the Devonian to Mississippian Finlayson assemblage, the oldest arc of the composite YTT. The Tower Peak unit is a massive but fractured, sub-greenschist facies metabasalt. Whole-rock and trace element geochemistry of four Tower Peak samples suggest an oceanic or island arc setting for deposition of the Tower Peak unit. Zircons separated from three samples of the Tower Peak unit give a range of U-Pb ion probe ages. Three distinct age populations exist: 600-2582 Ma, 433-303 Ma, and 140-190 Ma. The preferred interpretation is that the Tower Peak unit is Mesozoic in age and may derive from Stikinia or Quesnellia.

This thesis will examine intensively “The Tower of Babel: A Morality” a significant work of Thomas Merton, a major spiritual writer of the 20th Century, entitled. In order to explore this play three other works which impacted significantly on the development of the drama will also be examined. These three works are: A poem also called “Tower of Babel”; a second poem entitled “A Responsory” and a musical work titled “The Tower of Babel: An Oratorio”. Even though Victor Kramer, a Merton scholar, noted the significance of the Morality, the existing literature has all but ignored the impact of “The Oratorio” and the drama. Until this author requested a copy of “The Oratorio” from the Merton Centre in Louisville, Kentucky the work had been known by name only and had never been analysed. Yet this work was a major development from the poem “A Responsory” and led to the creation of the Morality Play. This work argues that “A Morality” was pivotal in contributing to personal and spiritual change in Merton as well as developing a greater depth of social understanding in him. It will also argue that the work contained the seeds of future Merton writings. Writing the drama moved Merton towards a contemplative maturity based on communion not simply community. While many studies have alluded to the play none of them have studied it with this particular focus. This new focus is the discovery of the ways Merton attempted to resolve the dilemma he experienced between the paths of monk and poet and how, in doing so, he created for spiritual seekers a fresh inner significance for the Babel story. This work is opening up new ground for an understanding of the importance of Merton’s insights in the contemporary world. The methods used in this thesis are: 1. Contextualising, that is establishing the historical, social, spiritual and literary framework in which the poems and plays were written, and 2. Literary analysis. Part A of the thesis examines the monastic, spiritual, social, literary and academic contexts which brought Merton to the moment of writing the Morality. Part B is organised chronologically and is an intensive analysis of the poems, the Oratorio and the Morality Play. Part C identifies the seeds of future growth contained within the Morality play and points to some of the directions in which these seeds developed in later Merton works.

This recital explores the solo viola literature of the 20th and 21st centuries. Pieces range in date from 1922 to 2005 and present the various styles and techniques of virtuoso viola playing developed in the modern era. The selection of pieces presented on this recital chronicles the viola���s journey to become a legitimate solo instrument in the 20th century. Works performed include: Cadenza per viola sola by Krzysztof Penderecki, Purple Rhapsody for Viola and Orchestra by Joan Tower, Suite for Viola Solo (Unfinished) by Ernest Bloch, Lamentations of Jeremiah for Viola Solo by Milton Barnes, and Sonata for Viola and Piano Op. 25 No. 4 by Paul Hindemith. Works by both male and female composers are presented, and a wide variety of compositional styles are represented, including works by Polish, American, Canadian, and German composers. <br>Works performed encompass three periods of the modern era: Hindemith - early 20th century, Bloch and Barnes - mid-20th century, Penderecki and Tower - present day. / Mary Pappert School of Music; / Music Performance / MM; / Recital;

This thesis presents a thermodynamic model for a screw chiller and cooling tower system for the purpose of developing an optimized control algorithm for the chiller plant. The thermodynamic chiller model is drawn from the thermodynamic models developed by Gordon and Ng (1996). However, the entropy production in the compressor is empirically related to the pressure difference measured across the compressor. The thermodynamic cooling tower model is the Baker & Shryock cooling tower model that is presented in ASHRAE Handbook - HVAC Systems and Equipment (1992). The models are coupled to form a chiller plant model which can be used to determine the optimal performance. Two correlations are then required to optimize the system: a wet-bulb/setpoint correlation and a fan speed/pump speed correlation. Using these correlations, a "quasi-optimal" operation can be achieved which will save 17% of the energy consumed by the chiller plant.

This thesis uses aluminum porous board (AP board) to study the noise reduction for cooling tower. It sets the barrier to isolate the sound propagation. But it will happen diffracted phenomenon when sound wave impinging at the edge of barrier. So the mathematical model of acoustic diffraction on the barriers, which is set up by Hayek, is applied in this thesis. Base on this theorem, the AP board and the paths of sound propagation are analyzed. In experiment, it uses the sound intensity method to measure the cooling tower for determining the major source first. The major source is determined by ranking the sound power. And the suitable insulation material is selected by analysis the frequency band of major source. After analyzing, the major source of cooling tower is the region of fans by motor driven that is located upper the cooling tower. And its frequency range is between 25 Hz to 2500 Hz. So the AP board is a candidate since it has broadband characteristic on noise insulation. After aim of the major source, the noise barrier is studied for noise reduction. In this thesis, the U profile of barrier (looking down from above), which considers the situation in the field, is designed to surround the cooling tower. This barrier is made of aluminum board, and the aluminum porous board is applied to add on the upper barrier for noise reduction. To study the acoustic diffraction on the boundary of barrier, the thick of porous board is added on the upper barrier. The insulation effect is compared in the different condition after measuring the transmission loss. The T shape barrier is also designed for noise reduction evaluating in this thesis. Finally, the best-insulated effect is obtained when the complex board is added on the upper barrier. And the noise level is down to 59 dB around the environment. This result is matched the EPA noise standards.

The breakthrough technology in dry fiber fabrication has opened the possibility for using fiber bandwidths all the way from 1.3 to 1.6 £gm. However, the fiber amplifier used in commercial product, such as erbium-doped fiber amplifier (EDFA), can not fully cover the whole fiber bandwidths from 1.3 to 1.6 £gm with a single fiber amplifier. Recently, the Cr4+-doped fiber has shown a broadband emission from 1.3 to 1.6 £gm. Therefore, it is interesting to develop a single fiber amplifier which can operate the wide bandwidth of the 1.3 ~ 1.6 £gm emission. In this study, we have successfully fabricated and measured the Cr-doped fibers by using a commercial drawing-tower technique. The Cr-doped YAG preform was firstly fabricated by a rod-in-tube method. By employing a negative pressure control in drawing-tower technique on the YAG preform, the Cr-doped fibers with a better core circularity and uniformity, and good interface between core and cladding were fabricated. The drawing speed was up to 200m/min. The core diameters were 26 and 16 £gm and the non-circularity was smaller than 3%. The spontaneous emission spectrum showed a broadband emission of 1.2 to 1.6 £gm with the output power density about a few nW/nm. The Cr-doped fibers fabricated by drawing tower are beneficial when integrated with the standard single-mode fibers and broadband WDM couplers for lightwave communication systems. Therefore, the Cr-doped fibers may be used as a broadband fiber amplifier to cover the whole 1.3-1.6 £gm range of silica fibers and have a potential for commercial production and application to lightwave communication systems.
