Surface mining activities are known to affect the quantity and quality of stormwater runoff. This can create flooding and water quality degradation of receiving streams. The Surface Mining Control and Reclamation Act (SMCRA) of 1977 provides regulations intended to produce environmentally acceptable results from mining operations. The SMCRA requires that extensive pre-mining monitoring be carried out to assist in determining the probable hydrologic consequences (PHC) of mining. The Finite Element Storm Hydrograph Model (FESHM) was used to demonstrate the utility of hydrologic modeling concepts in simulating runoff volumes and peak flows. Guidelines were proposed for using this methodology to simulate selected pre-mining hydrologic conditions. The use of geographic information system (GIS) technology as a tool for improving data management and modeling efficiency was demonstrated. The required input watershed characteristics were digitized, stored, and manipulated using a computerized GIS. Appropriate software was developed to integrate the GIS with FESHM. The ability of FESHM to simulate runoff events in an ungaged context was evaluated using an experimental watershed. First, simulations were conducted using two separate data bases, "lumped" and "detailed", in order to evaluate the effect of limited data availability, as expected in mining regions, on FESHM's predictive ability. The "lumped" data base produced better simulation results, however, more thorough and detailed research is needed to determine the level of data resolution necessary for a given level of simulation accuracy. Next., significant runoff events from 17-years of the historical record were simulated using data from the "lumped" data base. Statistical analyses were used to make judgments on parameter estimation and model usage. Regression methodology was used to assess expected error and model bias. Simulation bias was found to be related to the input rainfall intensity levels. The results suggest that either spatial variability or parameter values were not adequately defined and that some form of calibration is needed. Two additional drainage basins were used to evaluate FESHM's predictive capabilities in situations considered representative of mining regions. The results indicated that more thorough investigations of watershed characteristics must be made, that calibration procedures should be performed for each watershed, and that FESHM does not adequately model the physical processes involved in forest hydrology. / Master of Science

This thesis presents an analytic solution for the stress distribution in a semi-infinite strip subjected to symmetrical loads on the transverse edge. Three different types of loading on the transverse edge are considered: (i) a segment of uniform load, (ii) two concentrated normal loads, and (iii) two concentrated tangential loads. The solution is constructed by the method of images. Under successive reflections the given strip and the resulting images become a semi-infinite plate with a series of periodic loads on the edge. The stress function for such a plate is constructed by superposing the known solutions of a simple nature. To satisfy the boundary conditions along the longitudinal edges of the semi-infinite strip, additional stress functions are introduced. When the boundary conditions are adjusted, a system of integral equations and a system of algebraic equations are obtained, which are further reduced. to a single system of algebraic equations. The latter system is solved by the method of successive approximations. In each case, the expressions for normal stresses along the longitudinal axis are derived and numerical values for these stresses are given. / Master of Science

The object of this thesis is to establish the necessary design criteria for a number of special feedback networks which were required to allow the final development of the Strip Mining Industry's first Automatic Crowd-Hoist Regulator. The introduction considers the purpose and needs for such a regulator by briefly outlining the present manual dipper loading operation. Section IV and Appendix 1 presents the analytical system requirements which are basically determined from an analysis of the system's inherent mechanical oscillatory frequency. Section VA is concerned with the development of the hoist and crowd motion transfer functions which are necessary to accomplish the stability analysis of the system. A general determinantal solution is obtained based on linear analysis to allow expression of the motion transfer functions as a factored polynomial. In section VB, the development of the necessary Crowd-Hoist feedback circuits is accomplished in terms of the system parameters defined from the analysis of the oscillatory mechanical system. Section VIA outlines the procedures to be followed in going from the basic mechanical system parameters to the specific control system hardware. The general requirements for a Bode analysis of the system GR is defined in section VIB, including the general procedures to follow in the utilization of the two lead compensation circuits provided. / M.S.

This master's thesis is a study of the comic strip and its tradition in the Czech Republic. It covers development of this format and its occurrence in Czech periodicals as well as the gradual use of comics' visual language and different views on the comic strip definition. Taking views from several different perspectives including artists, writers, magazine editors and publishers this thesis will show the principles of cooperation between the comic creator and the editors of the magazine in which it is published. This is supported by original research (see Appendix) and has the goal of showing the motivations, perceptions and approaches to the comic strip from the perspective of the creator as well as the magazine editor. The research uses case studies based on structured interviews with editors of cultural magazines in the Czech Republic and with the creators of the comic strips that they publish. The results of this research combined with the historical and contemporary context offer a close look into the current perception of the comic strip as a format for creative expression, but also the magazine editor's responsibility in publishing the comic strip.

Esta tese baseia-se em trabalho etnográfico que investiga performances de gênero em um Clube de Mulheres no Rio de Janeiro, onde, após um show de strip-tease masculino para uma platéia exclusivamente feminina, tem início uma festa dançante com a presença de público masculino. No espetáculo são encenados atos (hetero)sexuais em duplas ou em grupo, envolvendo os strippers e as mulheres que voluntariamente sobem ao palco. A trilha sonora, marcada pelo estilo pornofunk, traz elementos alusivos à infidelidade conjugal masculina e feminina, à orgia e à prostituição masculina e feminina. Como em rituais de inversão, há, durante o show, tanto uma suspensão controlada das convenções de gênero tradicionais, quanto sua paradoxal reafirmação. Para o deleite de um público feminino, os strippers mantêm no palco a representação do papel ativo na cópula, e tanto sua hexis corporal quanto suas performances realçam a prontidão para o ato sexual, a virilidade e o controle sobre a conduta feminina. As mulheres, por sua vez, encenam uma parcial submissão ao controle masculino. Elas manifestam alguma reatividade e heteronomia em relação aos homens na festa que acontece depois, quando pares heterossexuais relativamente anônimos interagem através de aproximações sucessivas que englobam carícias e beijos na boca. Neste contexto, como sujeitos ou objetos, tanto os strippers quanto as mulheres desempenham posições conflitantes com as tradicionais expectativas de gênero, que permanecem, entretanto, preservadas em grande medida pela idéia de que elas dependem de estímulos especiais para, no campo do erotismo e da sexualidade, desejar ou fazer coisas para as quais os homens estariam supostamente sempre prontos. A tese procura mostrar que, como espécie de preço a pagar pelas inversões que ocorrem nesse espaço, tanto a imagem das mulheres quanto a dos strippers é desvalorizada, recaindo sobre eles os estigmas que ainda cercam as rupturas relativas às convenções de gênero. / This dissertation is based on an ethnographic study about gender performances in a Womens Club in Rio de Janeiro. After a male strip-tease show exclusively for a womens audience, starts a dancing party and the presence of men is allowed in the club. During the show, heterosexual activities between the women from the audience and the strippers are simulated on the stage. Most of the songs played during the show in the so called pornofunk style - bring several references to sexuality and gender roles, such as male and female marital infidelity, sexual orgy and male and female prostitution. As a kind of ritual of inversion, during the show, there are both a suspension and a reiteration of traditional gender rules and conventions. As objects for the erotic fruition of the women in the audience, the male strippers sustain nonetheless an active role through the simulated sexual practices, and both their body presentation and their performance demonstrate sexual promptness, virility and control over female behavior. Despite the fact that they are paying for the show, and in this way occupying a position traditionally reserved to men in Brazilian society, the women brought to the stage show a partial submission to male control. After the show, when the male audience is allowed inside the club, anonymous heterosexual couples interact by successive approaches that include kissing, petting, or cuddling. Women then show a more conventional gender performance, even though they are more sexually open and receptive. Sexual and gender conventions are largely maintained by the idea that women depend on special stimulus to do or desire to do things that men are supposed to be always ready to in the field of eroticism and sexuality. These conventions are also reinforced by the social stigma that is attached both to the male strippers always suspect of being gays or prostitutes - and to the female audience, seen by many as sexually and morally dishonest.

Cette thèse a pour objectif premier de dresser un inventaire des albums et des feuilletons de bande dessinée publiés à Paris et à Genève, à partir des « histoires en estampes » de Rodolphe Töpffer jusqu’aux séquences de Christophe publiées dans Le Petit Français illustré. L’établissement du catalogue amène à élargir le cadre initial de la recherche pour aborder diverses formes de récits en images que voit se développer le XIXe siècle. À partir de là, il s’agit d’envisager la bande dessinée à travers ses principaux supports éditoriaux (l’album et la presse illustrée, mais aussi l’imagerie populaire représentée par la collection de la maison d’édition fondée par Albert Quantin), et de comprendre en quoi le dispositif de diffusion influe sur le medium en devenir. Une mise en relation de ces différentes formes s’attache ensuite à définir les langages de la bande dessinée : les usages faits de l’image et du texte, les thématiques privilégiées et notamment la teneur parodique des œuvres. La bande dessinée est ainsi placée dans l’évolution des poétiques et de l’expression visuelle, dans l’histoire de l’imprimé et des média. / This thesis has for first goal to make an inventory of the albums and serials of comic strip published in Paris and in Geneva from Rodolphe Töpffer’s “stories in prints” up to Christophe's sequences printed in The Small illustrated Frenchman. Once the catalogue established it becomes possible to widen the initial framework of the research and approach the different forms of narratives in images that develop during the XIXth century. From there, the comic strip can be studied through its main editorial supports (the album and the illustrated press, but also the popular imaging represented by the collection of the publishing house established by Albert Quantin), and one can understand in which way the modes of dissemination influence the progress of the medium. It gets thus easier to define the languages of the comic strip: the manners images and texts intertwin, the main themes and in particular the continuous parodic mood of the works. The comic strip eventually finds its place in the evolution of the literary and visual expressions as well as in the history of printing and of the media.

The implications of comminution practices on the planning of a typical open pit mine was investigated in this study by means of computer simulation. The objective was to assess the effects of mining costs as well as processing costs on the production plan of a typical open pit mine. For the purpose of the research, MineLib, an open library of ore body models was consulted. This led to the selection of a copper-gold ore body named “Newman1” for use in the strategic mine optimisation. Various scenarios were considered in order to highlight the contribution of comminution costs to the mine plan. In all the simulated scenarios, the objective function was to maximise the Net Present Value (NPV). And in terms of simulation setup, the comminution costs and cut-off grades were systematically varied from 70 % to 140 %. It was hence possible to investigate their effects on the NPV of the Newman1 ore body using SimSched, a freeware for mine optimisation and planning. Results showed that there is a great opportunity to increase the NPV of the Newman1 block model by adjusting the contribution of processing costs in general and comminution costs in particular. This can be achieved for instance by controlling the policy of cut-off grades, lowering production costs, and increasing throughput. / Civil and Chemical Engineering / M. Tech. (Chemical Engineering)
