Aaron Copland's Symphonic Use of Brass InstrumentsHasty, Patrick R. (Patrick Robert) 08 1900 (has links)
Traditions in orchestration can be described by relating the practices of most of the important composers of a particular time. This was done with great success by two composers of the nineteenth century, Hector Berlioz and Nicolai Rimsky-Korsakov, in their books on orchestration. These texts are the basis for the traditional uses of brass instruments appearing in the chapter.

The Welsh Crwth, Its History, and Its GenealogyBevil, J. Marshall (Jack Marshall) 08 1900 (has links)
In the early years of the nineteenth century, when bowed string instruments were assumed to have reached the apex of their development, there arose among antiquarians and scholars a widespread interest in tracing the ancestry of the violin and related members of the chordophone family. This task proved to be exceedingly formidable not only because of the enormous amount of often obscure evidence which had to be taken into consideration but also because of the manner in which many items of evidence seemed to contradict each other. The issue is still not resolved to the complete satisfaction of every party concerned. Literally scores of different and often conflicting arguments have been advanced, and it could perhaps be justly said that the only furtherance thus far realized has been that of the confusion rather than the resolution of the issue.

Concepts de base d'une méthode novatrice de détection et d'identification de systèmes optiques et de réduction de fausses alarmesAuclair, Michel 19 April 2018 (has links)
Le monde militaire s’intéresse à la détection de systèmes optiques présents dans un milieu urbain. La raison de cet intérêt est que la présence de systèmes optiques peut être directement ou indirectement reliée à des activités hostiles. Cette visée consiste en un défi de taille car l’environnement urbain contient de nombreux éléments pouvant être confondus aux systèmes optiques, générant alors de fausses alarmes. Au cours de cette thèse, les concepts de base d’une méthode de détection novatrice permettant de détecter et d’identifier la présence de systèmes optiques ainsi que de diminuer les fausses alarmes sont présentés et vérifiés expérimentalement. Ces concepts sont fondés sur l’établissement d’une signature propre aux systèmes optiques construite à partir de la mesure de leur section efficace laquelle est fonction de la longueur d’onde de la source d’interrogation. Une plateforme de détection a été conçue afin de mesurer la section efficace des systèmes optiques en utilisant le principe de rétro-réflexion. Cette plateforme contient des sources lasers de longueurs d’onde différentes, une caméra à crénelage spatial, un tube télescopique pour l’émission et la collection des rayonnements ainsi qu’un télémètre laser. Les résultats expérimentaux ont permis de valider les concepts de la méthode proposée en détectant et identifiant correctement les systèmes optiques en plus de les différentier des fausses alarmes, ouvrant ainsi la voie à un traitement nouveau de l’information pour ce type d’application.

Development and application of a new passive sampling device : the lipid-free tube (LFT) samplerQuarles, Lucas W. 29 September 2009 (has links)
Contaminants can exist in a wide range of states in aqueous environments, especially in surface waters. They can be freely dissolved or associated with dissolved or particulate organic matter depending on their chemical and physical characteristics. The freely dissolved fraction represents the most bioavailable fraction to an organism. These freely dissolved contaminants can cross biomembranes, potentially exerting toxic effects. Passive sampling devices (PSDs) have been developed to aid in sampling many of these contaminants by having the ability to distinguish between the freely dissolved and bound fraction of a contaminant. A new PSD, the Lipid-Free Tube (LFT) sampler was developed in response to some of the shortcomings of other current PSD that sample hydrophobic organic contaminants (HOCs). The device and laboratory methods were original modeled after a widely utilized PSD, the semipermeable membrane device (SPMD), and then improved upon. The effectiveness, efficiency, and sensitivity of not only the PSD itself, but also the laboratory methods were investigated. One requirement during LFT development was to ensure LFTs could be coupled with biological analyses without deleterious results. In an embryonic zebrafish developmental toxicity assay, embryos exposed to un-fortified LFT extracts did not show significant adverse biological response as compared to controls. Also, LFT technology lends itself to easy application in monitoring
pesticides at remote sampling sites. LFTs were utilized during a series of training exchanges between Oregon State University and the Centre de Recherches en Ecotoxicologie pour le Sahel (CERES)/LOCUSTOX laboratory in Dakar, Senegal that sought to build "in country" analytical capacity. Application of LFTs as biological surrogates for predicting potential human health risk endpoints, such as those in a public health assessment was also investigated. LFT mass and accumulated contaminant masses were used directly, representing the amount of contaminants an organism would be exposed to through partitioning assuming steady state without metabolism. These exposure concentrations allow for calculating potential health risks in a human health risk model. LFT prove to be a robust tool not only for assessing bioavailable water concentrations of HOCs, but also potentially providing many insights into the toxicological significance of aquatic contaminants and mixtures. / Graduation date: 2010

Klavírní spolupráce. Specifické umění klavírní hry / Piano accompaniment. The specific art of piano playingPapežová Erlebachová, Marie January 2021 (has links)
This thesis focuses on the topic of piano accompaniment, which is an essential and beautiful part of piano playing. This field demands from the pianist a specific approach, which is a subject and core of many study programmes throughout the world. The aim of the first part of this thesis is to map the evolution as well as the current state of knowledge in the field of piano accompaniment using scientific literature on the subject as well as curricula of study programmes obtained from universities in central Europe, where piano accompaniment is taught as a major study course. A strong correlation has been established based on this research between theory in scientific literature on the subject and the current practice of piano accompaniment education in central Europe. The aim of the second part of this thesis is to expand further the level of knowledge in scientific literature, which is insufficient mainly in the accompaniment of solo musical instruments. For this reason, the second part of the thesis focuses on the specific problems in piano accompaniment of musical instrument groups, i.e. string instruments, woodwind instruments and brass instruments. For these three groups case studies have been created, which examine the specific characteristics of the musical instruments in relation to piano...

"Does size matter?" - En kvalitativ undersökning om påverkande faktorer gällande styrmedel i småföretagHolm, Martina, Thorstensson, Adam, Wijk, Emma January 2014 (has links)
För att upprätthålla en ekonomisk hållbarhet inom ett företag krävs ett ansvarsfullt företagande inom organisationer, vilket skapar behov av ett systematiskt arbetssätt med ekonomiska styrmedel. Olika styrmedel kan vara relevanta för olika syften, varför valet och användandet av dem är kritiskt att studera. Studien undersöker därför genom en komparativ fallstudie vilka faktorer som påverkar valet och användandet av styrmedel i småföretag i Sverige. Undersökningen resulterar i ett antal faktorer som enligt fallföretagen påverkar hur besluten om styrmedel tas. Dessa faktorer ligger som grund för den modell som skapats. Modellen visar att informationsbehovet hos ledaren är det som påverkar hur valet och användandet sker samt att behovet förändras beroende på företagets och omvärldens karaktär tillsammans med ledarens bakgrund. / Maintaining economic sustainability within a company requires a responsible business organization that creates the need for a systematic approach to economic instruments. Different instruments may be relevant for different purposes and therefor the choice and use of them is critical to study. The study examines, through a comparative case study which factors influence the choice and use of economic instruments in small businesses in Sweden. The survey results in a number of factors that, in the studied companies affects how decisions on financial instruments are made. These factors form the basis of the model created. The model shows that the informational needs of the leader is what influences how the selection and use takes place, and that need is changing depending on the company and the external characteristics along with the background of the leaders.
