abstract: John Harbison is one of the most prominent composers of the twentieth and twenty-first centuries. He has made major contributions in all areas of classical music, including operas, symphonies, chamber music, choral works, and vocal pieces.Among his vast output is 'Four Songs of Solitude,' his only composition (to date) for solo violin. Though the piece is beautiful and reflective in nature, its inherent technical and musical difficulties present challenges to violinists preparing the piece. There is no published edition of 'Four Songs of Solitude' that includes bowings and fingerings, and violinists used to practicing and performing the études and repertoire of the eighteenth and nineteenth centuries may have difficulty determining how to successfully navigate the music. This paper examines the piece in detail, providing an analytic description of the music and suggestions for practice. An interview with the composer yielded many insights into the structural and harmonic events of the songs, and the composer's interpretive suggestions are given alongside technical suggestions by the author. The solo violin has a centuries-long legacy, and some of the most performed repertoire exists in the medium. 'Four Songs of Solitude' is a demanding set of pieces that stands out in late twentieth-century violin music. Providing information about the piece directly from the composer and suggestions for practice and performance increases the accessibility of the work for violinists seeking to bring it to the concert stage. / Dissertation/Thesis / D.M.A. Music 2012

Afin de répondre aux besoins croissants d’équipements de communication pour les applications spatiales, il est important de réduire, le plus possible, la taille et la masse de l’équipement des satellites. Cela conduit à une réduction des coûts de lancement des satellites sur leur orbite ou laisse la possibilité d’ajouter des équipements dans la fusée. Ceci compte aussi pour les composants radioélectriques. L’objectif étant de réduire les dimensions sans pour autant détériorer les performances en rayonnement (directivité, polarisation croisée, bande monomode, etc.). Il est possible de contrôler la propagation des ondes électromagnétiques dans les antennes cornets et les guides d’onde à l’aide de surfaces anisotropes (corrugations, métamatériaux). Ainsi, contrairement à ce que prédisent les lois physiques sur la propagation et le rayonnement d’ondes électromagnétiques dans des structures classiques, les performances des structures à parois anisotropes peuvent être radicalement améliorées : pour le guide d’onde, réduction de la fréquence de coupure ; pour l’antenne cornet, amélioration de la directivité ou réduction du niveau des lobes secondaires. D’après l’état de l’art, même si les résultats de simulations et de mesures obtenus sont très prometteurs, le dimensionnement de la structure des métamatériaux est sujet à optimisation, donc gourmand en ressources informatiques. L’apport principal de cette thèse a été de développer une nouvelle méthodologie de conception s’appuyant sur une Théorie Modale Elargie (TME) analytique pour des guides d’onde à parois anisotropes. Elle permet de dimensionner très rapidement des surfaces à métamatériaux les plus adaptées aux applications requises. Un prototype de guide d’onde et un prototype d’antenne ont été conçus, fabriqués et mesurés grâce à cette méthodologie. Les résultats obtenus démontrent l’intérêt, l'efficacité et le caractère général de la méthode proposée pour la conception de dispositifs hyperfréquences guidés à parois anisotropes. / In space applications, one of the biggest challenges is to reduce the size and mass of equipment, in order to reduce the costs of the rocket launch. For RF components, this has to be done without lowering RF performance (directivity, crosspolarization, single-mode bandwidth, etc.). The challenge is all the more problematic in the case of used horn antennas and waveguides because of their relatively large size. It has been shown that the use of anisotropic surfaces (i.e. corrugations and metamaterials) on the inside walls of guided RF structure makes it possible to influence and control the way electromagnetic waves travel, enabling new devices with radically different and improved performances : for waveguides, reduction of the cuto&# 64256; frequency ; for horn antennas, improvement of the directivity or a reduction of the side lobes. A state of the art of previous work done on metamaterial horn antennas pointed out that, even if the obtained and presented results seem very promising, the procedure to obtain the optimized RF structure is very time-consuming and requires considerable computer resources. The main contribution of this PhD work was to develop a new methodology based on the analytical Modal Expansion Theory (MET) for waveguides with anisotropic walls. This methodology makes it possible to optimize very rapidly the dimensions of the metamaterial surfaces adjusted to the required application. A metamaterial waveguide and antenna prototype have been designed, realized and measured thanks to this methodology. The results obtained demonstrate the usefulness, effectiveness and general applicability of the method developed for the design of RF structures with anisotropic walls.

Abordagens ágeis de gestão apresentam-se como uma alternativa para projetos com duração curta e requisitos que mudam no decorrer do projeto. Existem algumas abordagens que trabalham o gerenciamento ágil de projetos, como por exemplo: Agile Project Management, Agile Project Management Framework, Extreme Project Management e Scrum, que possuem princípios e práticas em comum. Elas surgiram como uma evolução das metodologias ágeis de desenvolvimento e possuem sua principal fundamentação no Manifesto Ágil para o Desenvolvimento de Software. Contudo, nenhuma dessas abordagens leva em consideração o PMBOK® Guide como conjunto de práticas já utilizadas no gerenciamento de projetos. Deste modo, a tendência é que surja um modelo híbrido entre clássico e ágil a fim de unir as vantagens das duas abordagens em prol do gerenciamento e desenvolvimento de projetos de sucesso, na visão do cliente e da equipe de projeto. Tendo em vista essa tendência e partindo da premissa de que um conjunto de práticas em gerenciamento ágil baseado no PMBOK® Guide pode ser mais eficiente quando se trata de projetos que necessitam de um pouco de rigor na sua execução e de um processo bem definido, mas que possuem seu foco em resultados ágeis, o objetivo desta dissertação é apresentar o Agilius: uma abordagem de Gerenciamento Ágil de Projetos de Software baseada no PMBOK® Guide. Para avaliar o Agilius foi utilizado o método apresentado pela Engenharia de Software Experimental. Foram definidos os objetivos, as questões usadas para a medição e um conjunto de métricas para caracterizar a análise destas questões. Em seguida, o planejamento do estudo experimental e a execução do estudo experimental foram realizados e ao final, para a verificação das hipóteses levantadas foi realizada a análise e a interpretação dos dados coletados a partir de estatística descritiva, análise qualitativa e quantitativa. De acordo o estudo experimental executado, o Agilius pode ser considerado ágil por contemplar de forma satisfatória as principais características que definem o gerenciamento ágil de projetos de software

Detta arbete handlar om antivirusprogram och vad det finns för hjälpmedel för hemanvändare utan teknisk bakgrund att finna det antivirusprogram som passar dem bäst. Målet med arbetet är att producera en guide för hemanvändare som ska hjälpa dem inför deras val av antivirusprogram. I detta arbete har tre olika metoder använts för att besvara de frågor och den hypotes som ställts. Först gjordes en litteraturstudie där bakgrundsmaterial inhämtades. Nästa steg var att genomföra intervjuer med experter inom området för att ta reda på vad guiden skulle innehålla. Som sista steg utfördes en enkätundersökning som riktade sig till hemanvändare för att ta reda på om den framtagna guiden besvarade hypotesen. Enkätundersökningen besvarades av både hemanvändare med och utan teknisk bakgrund. Detta gjordes för att få fram synpunkter på om guiden var tillräckligt lättförståelig för en hemanvändare utan teknisk bakgrund och för att ta reda på om guiden skulle hjälpa dem inför deras val av antivirusprogram. Resultaten av enkätundersökningen ledde oss fram till slutsatsen att en guide för hemanvändare behövs och att den guide som producerats i detta arbete skulle kunna vara till hjälp för hemanvändare inför deras val av antivirusprogram.

“The World Customs Organization Arusha Declaration for customs integrity proposes two elements to improve integrity: simplification of procedures, including automation, and adequate human resource management. The declaration, along with the Integrity Development Guide, a set of comprehensive integrity tools specifically designed to help customs administrations implement the principles contained in the Arusha Declaration, casts light on customs reform and modernization from the angle of fighting corruption, as improving integrity should be a cornerstone of any capacity building activities.” <ul> <li>Kunio Mikuriya, Deputy Secretary General, World Customs Organization In J.Edgardo C and S.Pradhan (eds) (2007) 367,The Many Faces of Corruption: Tracking Vulnerabilities at the Sector Level, Washington DC, World Bank.</li> </ul> Customs inefficiencies are well known to impede the integration of developing countries into the global economy. There are a number of bottlenecks to trading across borders. Among these bottlenecks, with their attendant costs, are: Excessive documentation, inadequate procedures and lack of audit-based controls; lack of risk assessment and management techniques; lack of modern infrastructure; lack of automation and use of computerized procedures; and lack of transparency. All these couples together create an environment rife with corruption as traders seek to process their transaction at whatever cost. Paying bribes then becomes the order of the day and result into an added cost to trading. In this era of globalization, an enormous demand has been placed on customs administrations especially in Africa to simplify their procedures so as to enable firms to participate meaningfully in international and regional trade. The complexity and costs of transactions, including corruption must be eliminated, thus the urgent need for trade facilitation. This study seeks to emphasize the potential of trade facilitation as a policy measure that can reduce the prevalence and negative effects of corruption in customs. While obviously not a cure-all for the wide variety of corrupt transactions taking place in customs administrations, this study will show that trade facilitation can nonetheless be of considerable help in dealing with corruption in customs. / Dissertation (LLM)--University of Pretoria, 2010. / Centre for Human Rights / unrestricted

In the present work we study methodology of different kinds of sample surveys and their design in SAS software. Creating of SAS Enterprise Guide Add-In was the fundamental creative part of this work. This Add-In enables to compute important statistics of sample surveys, without need of being familiar with SAS code. Add-In was created in MSFT Visual Studio 2003 in C # language using a tamplate for Add-Ins provided by SAS. This work contains a general description of the creation of an Add-In as well as the description of the created Add-In for handling the sample surveys and its usage.

The diploma thesis is focused on current supply of guide services in the UNESCO cities in Morava region. Guide services in Třebíč are analysed more detailed. The main goal of the thesis is to find changes in supply of guide services, when the current situation is compared to the situation in 2005. I used the diploma thesis of former student of the University of Economics in Prague from 2005 for this comparison. The next goal is comparison of supply of guide services between each other UNESCO cities. In this comparison, the main attention is paid to Třebíč and its supply. It is analysed, how wide is the range of guide services and offer of language versions compared to other UNESCO cities in Morava region.

Judith Weir (b. 1954) composed King Harald’s Saga: Grand Opera in Three Acts for Unaccompanied Solo Soprano Singing Eight Rôles (1979) for radio broadcast. She wrote the libretto for the opera based on Snorri Sturluson’s book, King Harald’s Saga. This opera illustrates Weir’s remarkable compositional style, including her treatment of the libretto in narrative style and her representation of multiple characters by one singer. Despite Weir’s fame as an opera composer, King Harald’s Saga is rarely performed owing to three major musical and performing challenges. These challenges are performer’s ability to delineate eight separate characters (dramatic challenges), to sing wide leaps and long melismas (vocal challenges), and to perform a cappella with wide leaps and complex rhythms (musical challenges). This dissertation presents a performance guide for the soprano addressing these three challenges and suggesting possible solutions. Such a guide will assist the soprano in preparing and performing this grand opera, which thus far has not received the due attention and appreciation of either performers or audiences.

abstract: Throughout history composers have used music to depict their perception of the refugee experience. This project expands upon this idea through the commission and recording of four new works for saxophone. The compositions are Different Arks for solo alto saxophone by John Secunde, Rubble/Resolve for alto saxophone and piano by Jared Yackiw, Emerging Light for soprano saxophone and vibraphone by Alan Hankers, and Unam aeternam for solo alto saxophone and stereo playback by Ashlee Busch. For each work, this project provides performance guides, biographical contexts, program notes, and recordings. I hope to encourage artists to discover and facilitate creative ways to draw attention to migration around the world and contribute to the fight against racism and xenophobia. / Dissertation/Thesis / Doctoral Dissertation Music 2020
