The purpose of this study was to acknowledge and bring to light the undeniable significance of Benjamin Britten as a composer and his Piano Concerto in D, Op.13. This dissertation delved into the depth of the concerto with structural and harmonic analysis along with suggested pedagogical methods and performance aspects.The first chapter included an introduction of the piano-concerto genre in general, motivation for the study of Britten's Piano Concerto, review of literature on Britten and the piano concerto, and methodology of the dissertation. The second chapter continued with an overview of Britten's life, accomplishments as a pianist, and his contribution to the piano repertoire in general. The third chapter provided a stylistic analysis on each movement of the concerto. It included structural analysis based on the formal, motivic, thematic, rhythmic, melodic and harmonic elements presented throughout the concerto. Additionally, possible technical challenges and suggestions for practice methods were recommended based on the issues of phrasings, articulations, dynamics, musical expressions and styles. Since each movement has its own unique titles such as Toccata, Waltz, Impromptu, and March, the origins of the genre and Britten's association with the terminology was also examined.The dissertation not only underlined the importance of Britten as a composer for the piano, it also revealed his distinct compositional characteristics shown in the piano concerto in relation to his other significant piano repertoire. The dissertation closed with a summary of the detailed analysis of the concerto and recommended further studies on Britten and his piano concerto. / School of Music

A hybrid operational amplifier compensation technique using Miller and multipath compensation is presented for multi-stage amplifier designs. Unconditional stability is achieved by the means of pole-zero cancellation where left-half zeros cancel out the non-dominant poles of the operational amplifier. The compensation technique is stable over process, temperature, and voltage variations. Compared to conventional Miller-compensation, the proposed compensation technique exhibits improved settling response for operational amplifiers with the same gain, bandwidth, power, and area. For the same settling time, the proposed compensation technique will require less area and consume less power than conventional Miller-compensation. Furthermore, the proposed technique exhibits improved output slew rate and lower noise over the conventional Miller-compensation technique. Two-stage operational amplifiers were designed in a 0.18µm CMOS process using the proposed technique and conventional Miller-compensated technique. The design procedure for the two-stage amplifier is applicable for higher-order amplifier designs. The amplifiers were incorporated into a switched-capacitor oscillator where the oscillation harmonics are dependent on the settling behaviour of the op amps. The superior settling response of the proposed compensation technique results in a improved output waveform from the oscillator.

Scholes como uma alternativa de investimento para produtores rurais dos Vales do Jequitinhonha e Mucuri. Ao fazer um estudo sobre os produtores rurais dos vales, percebe-se que a produ??o no campo ? voltada para a subsist?ncia, vendendo somente o excedente. Foi constatado que a falta de investimento no campo reduz em partes o n?vel de produ??o do produtor rural. A alternativa de investimento atrav?s do modelo de Black ? Scholes na precifica??o de op??es se faz necess?rio n?o somente para se ter um maior investimento no meio rural, mas sim, ser tamb?m uma outra forma de se obter renda com t?cnicas aplicadas na Bolsa de Valores, ajudando o homem do campo em ter uma estabilidade financeira baseada n?o somente em sua produ??o. ? realizado um estudo criterioso da equa??o diferencial parcial estoc?stica advinda deste modelo, no tocante ? determina??o de poss?veis simula??es de problemas enfrentados diante das volatilidades dos mercados na precifica??o de op??es. Para que o produtor rural utilize o modelo de Black ? Scholes ? interessante se observar como se comporta os seus par?metros. Ent?o foi realizado uma an?lise do comportamento do valor da precifica??o de op??es em rela??o aos par?metros do modelo de Black ? Scholes baseados em dados reais retirados da BM&FBOVESPA. ? apresentada uma breve compara??o do modelo de Black ? Scholes com o modelo Binomial, compara??o feita com um exemplo de obten??o do valor da op??o de compra e venda via Binomial e Black ? Scholes, e neste exemplo ? observado um melhor retorno para o modelo Binomial. ? observado ao longo da pesquisa que existem dois par?metros que mais oscilam nos mercados, que s?o a volatilidade e a taxa de juros. Para se fazer bons investimentos, o produtor rural deve ficar atento e ter ci?ncia do comportamento da oscila??o desses par?metros. Para se ter uma melhor representa??o da varia??o desses par?metros, ? feito uma compara??o entre o valor das op??es de compra e venda calculados pelo modelo de Black ? Scholes e Binomial. Para a taxa de juros o modelo Binomial apresentou valores fora do esperado em rela??o ao modelo de Black ? Scholes. Devido a car?ncia de informa??es a respeito de como se investir na Bolsa de Valores, ? criado uma cartilha que se encontra nos anexos desta disserta??o voltada para o produtor rural, sobre como fazer um investimento na Bolsa de Valores e quais procedimentos iniciais deve-se tomar para obter ?xito nos mercados. Desses estudos, conclui-se que ? poss?vel o produtor rural investir pequenas quantias de dinheiro e obter retornos significativos em rela??o ao investimento inicial. Podendo assim, aplicar parte desse dinheiro em seu trabalho no campo e tamb?m ter uma forma de renda quando os retornos das produ??es no meio rural n?o forem favor?veis. / Disserta??o (Mestrado Profissional) ?

Scholes as an alternative of investment for rural producer Jequitinhonha and Mucuri Valleys. When doing a study on the rural producers of the valleys, it is seen that the production in the field is turned for the subsistence, selling only the excess. It was noted that the lack of investment in the field reduces in parts the level of production of the rural producer. The investment alternative through Black model ? Scholes in the options pricing is made necessary not only in order that a bigger investment has been in the rural environment, but yes, to be also another form of income being obtained with techniques applied in the valuable Stock Exchange, helping the man of the field in having a financial stability based not only on his production. It is accomplished out a discerning study of the partial differential equation stochastic resulted from this model, regarding the determination of possible simulations of problems faced before the volatilities of the markets in the options pricing. For the rural producer to use the Black model ? Scholes is interesting it will notice how if it holds his parameters. Then there was accomplished out an analysis of the behavior of the value of the pricing of options regarding the parameters of the Black model ? Scholes based on retired real data of the BM&FBOVESPA. There is presented a short comparison of the Black model ? Scholes with the Binominal model, comparison done with an example of getting the value of the option of purchase and sale was seeing Binomial and Black ? Scholes, and in this example a better return is observed for the Binomial model. It is observed throughout the research that there are two parameters that more oscillate in the markets, which are the volatility and the interest rate. In order that good investments become, the rural producer must be attentive and have science of the behavior of the oscillation of these parameters. In order that there has been a better representation of the variation of these parameters, it is done a comparison between the value of the options of purchase and sale calculated by the Black model ? Scholes and Binomial. For the interest rate the Binomial model presented values out of the waited one regarding the Black model ? Scholes. Due to lack of information about how to invest in the Stock Exchange, it is created a primer that is in the annexes of this dissertation turned to the rural producer how to make an investment in the Stock Exchange and it is necessary to take which initial proceedings to obtain succeed in the markets. Of these studies, it is ended that the possible the rural producer to invest small amounts of money and to obtain significant returns regarding the initial investment. Being able so, to apply part of this money in his work in the field and also to have the form of income when the returns of the productions in the rural environment are not favorable.
