Este trabalho trata da construção de mapas quantitativos de alvos subaquáticos a partir de imagens de satélite. Especificamente, trata da estimativa de biomassa de prados de capim-agulha (Halodue. Wrightii) no litoral de Pernambuco a partir de imagens Landsat5. A coluna d’água altera, de maneira distinta e exponencial os diferentes comprimentos de onda eletromagnéticos distorcendo as correlações existentes entre os mesmos. Devido a isso, torna-se imprescindível eliminar a influência da coluna d’água a fim de que se possa fazer qualquer tipo de análise quantitativa relacionando alvos subaquáticos com a resposta espectral do mesmo. O método testado neste trabalho baseia-se na construção de bandas invariantes em relação à coluna d’água. As bandas invariantes em relação à coluna d”água são feitas a partir de pares de bandas. O coeficiente de determinação (r2) encontrado foi de 0,582 para o par de bandas (2,4) e de 0,709 para o par de bandas( 3,4) o que demonstra a eficiência do método testado. / This work approaches the making of quantitative maps of underwater targets based on satellite images, specifically, the estimate of biomass in seagrass (Halodue Wrightii) fields on Pernambuco’s coast taken from images of Landsat5. The water column distinctly and exponentially alters the different electromagnetic wave lengths, distorting the existing correlation between them. Because of this, it is crucial to eliminate the water column’s effect so that we can carry out different kinds of quantitative analysis relating underwater targets with their spectral response. The method tested in this work is based on the construction of bands that do not vary in relation to the water column. These invariable bands are made from pairs of bands. The determination coefficient (r2) found was 0.582 for the pair of bands (2.4) and 0.709 for the pair of bands (3.4), which shows the efficiency of the abovementioned method.

Mon travail de recherche a porté surl’étude de la réponse magnétique orbitale d’un gazd’électrons dans le potentiel cristallin d’un solide.Cette étude est dans la continuité du travail deLandau (diamagnétisme de Landau) et de Peierls,ce dernier ayant développé une formule de susceptibilitéorbitale valable pour les modèles cristallinsà une bande. L’objet de ma thèse a été degénéraliser cette formule à un nombre quelconquede bandes, travail réalisé à l’aide d’une théorie deperturbation invariante de jauge. Je me concentreparticulièrement sur l’étude des modèles à deuxbandes, afin de mettre en évidence l’importancedes couplages interbandes dans la susceptibilitéorbitale. Cela fait intervenir la courbure de Berry,grandeur classiquement associée à ces couplages,mais également le tenseur métrique qui joue unrôle crucial. En particulier, je montre qu’un isolantde bandes peut avoir une réponse magnétiquemême si sa bande de valence est remplie, et je metsen évidence un modèle où les propriétés géométriquespeuvent être variées tout en maintenantfixes les propriétés spectrales, ce qui induit desmodifications importantes de la réponse magnétique. / My research project has been to studythe orbital magnetic response of a electron gas inthe periodic potential of a crystal. Its purpose isto generalize Landau’s diamagnetism and Peierls’formula for one-band crystals. The main goal wasto generalize Peierls’ work to any number of bands.Then, I applied the obtained formula to 2-bandsystems in order to highlight the role of interbandeffects in the orbital susceptibility. The susceptibilitycan be written using Berry curvature, quantityassociated to interband effects, as well as the metrictensor. In particular, I show that a band isulatorcan have a non-vanishing magnetic responseeven if the chemical potential lies in the gap. Moreover,I study a model where the geometric propertiescan be tuned without changing the dispersionrelation. This tuning can drastically modifythe orbital magnetic response.

High school band members (N=13) and their teacher were observed during six rehearsals of two contrasting band compositions over a six-week period. The contrasting compositions were selected by means of a detailed process between me (the researcher) and the teacher (the conductor). One 60-second excerpt of each composition was selected, during the performance of which, the students were observed. Three video tapings of each composition was done in order to capture occasions when the students would look up from their music. Using a technique adapted from Ekman (1997), the band members and teacher were then interviewed in order to reveal the reasons they recalled for looking up from their music. The results showed that the band members looked up in places where the teacher expected eye contact, that the frequency of eye contact changed little from one rehearsal to the next, and that the frequency of eye contact changed little between the two contrasting compositions. In all cases, the band members were able to recall the reasons for looking up from their music, a fact which led to a detailed analysis about the students' own thoughts while they were engaged in playing as an ensemble. The results are discussed in terms of strategies for teaching practice and implications for future research.

The purpose of this thesis is the (1) study of the band class methods in use, (2) a discussion of their effectiveness, (3) an original attempt to show how many of the problems of band methods can be solved. It should be noted that a class of instrumental students may be a group of several or all different kinds of band instruments together. This study, however, will be concerned mainly with group instruction which combines all of the band instruments together. The term "method" as used herein designates a book of music material for class instruction in all band instruments. The term "instructor" is used to denote an instruction book written for only one instrument, for example, "trombone instructor".

This master’s thesis focuses on the issue of measurement of parameters of network traffic of wired and wireless networks. The first part theoretically describes SNMP protocol and application interface API, that form the basis for acquiring and evaluating data. The next section describes known MIKROTIK platform and software solutions for the alternative possibility of implementing a new feature. The last part closely describes the created application. It is a simple information system, whose task is to get information and evaluate it using the known functions. The conclusion of the work is a few tests of this application, assessing the real operation.

The purpose of the study was to investigate the leadership role of the Texas Bandmasters Association (1920-1997) in the development of the band program in Texas. It sought to determine TBA's effect on the band movement in Texas, and ascertain how the TBA has contributed to the emphasis on performance focus that is associated with the Texas band tradition. In doing so, the study also provided information regarding the association's goals, purposes, activities, and contributions during the time period under investigation. The historical data for the study was compiled from documentary sources and personal interview. Documentary sources included minutes of meetings from 1920-1997, information contained in various periodicals including the Southwestern Musician combined with the Texas Music Educator, and a nearly complete set of clinic-convention programs. Historical data from past researchers, including several masters theses and doctoral dissertations, and tapes and transcripts of interviews conducted by past researchers, as well as interviews conducted by this researcher, were also utilized. Much of the historical data for the study was located at the Texas Music Educators Association archives, housed at the association headquarters in Austin, Texas. The researcher identified five periods of the association's history. In addition to developing a historical chronology, the study identified prominent leaders for each historical period and explored how these individuals shaped the development of the association, which has grown from a small group of municipal bandmasters in 1920, into the largest state band association in the world, with over 2,200 active members. The researcher chronicles the events that led up to the first annual clinic-convention in 1948, and continues through the fiftieth clinic-convention in 1997. Although the first clinic-conventions focused on new music and the marching band exclusively, over the years this original concept has expanded and now encompasses virtually every aspect of band work. The study sought answers to the following research questions: (1) Who were the primary leaders of the association during each historical period? (2) What was TBA's leadership structure during each period? What was its effect on the growth and development of the association? (3) What were TBA's goals and activities during each historical period and to what extent were the goals of the association achieved? What role did the leadership play in achieving these goals? What were TBA's contributions to the band movement in Texas during each historical period? (4) TBA has come to find its present niche in the presentation of an annual clinic-convention centered, at least initially, on new music and the marching band. What was the role of the leadership in making this present state of affairs become reality? Using a previous leadership model, the researcher found that the leaders identified were mainly elected officers and/or executive secretaries of the association. The leadership structure changed over the years in order to meet the association's needs at the time. Goals, activities, and contributions were discussed for each historical period and evaluations were made regarding the extent to which the association's goals were achieved. Finally, the role of the leadership in making the current state of affairs become reality was discussed, as well as recommendations for further research.
