The Role Of Turkish Percussion In The History And Development Of The Orchestral Percussion Section, D. Doran Bugg Jan 2003

The Role Of Turkish Percussion In The History And Development Of The Orchestral Percussion Section, D. Doran Bugg

LSU Major Papers

The fascination of eighteenth century Western composers with the Eastern percussion instruments of the Turks was the impetus behind the initial use of percussion instruments in the orchestra. Consequently, the era beginning in the late eighteenth-century when percussion instruments were first included deserves reexamination. The objectives of this monograph include the examination of the manner in which composers first utilized Turkish percussion (excluding kettledrums) in the orchestra. This study then investigates the subsequent history of these instruments and manner in which composers utilized them, leading to their recognition as musical instruments in their own right. The findings of this study …

Snow-Patch Influence On Soil Biogeochemical Processes And Invertebrate Distribution In The Mcmurdo Dry Valleys, Antarctica, Michael N. Gooseff, J. E. Barrett, Peter T. Doran, Andrew G. Fountain, W. Berry Lyons, Andrew N. Parsons, Dorota L. Porazinska, Ross A. Virginia, Diana H. Wall

Faculty Publications

The McMurdo Dry Valleys is the largest of the ice-free areas in Antarctica. Precipitation events in excess of 1 cm of snow accumulation are rare. During the winter, snow is transported by strong katabatic winds blowing from the polar plateau, and deposited into the lee of topographic features (e.g., stream channels and other topographic depressions). At the start of the austral summer (early October), as much as 10% of the valley soils may be covered by distributed snow patches. Because liquid water is the primary driver of biological, physical, and chemical processes in this polar desert, quantifying fluxes of water …

Caller Id, Plamen Ivanov Arnaudov Jan 2003

Caller Id, Plamen Ivanov Arnaudov

LSU Master's Theses

As one might expect from a young poet writing at the turn of a millennium, recurrent in "Caller ID" is the theme of struggle with literary tradition and of seeing it as both necessary and constricting to the project of forging one's own creative identity. The collision between history and the self is visible in the often conflicted references to great philosophers and poets of the past as well as in the call for renewal of the body poetic after an envisioned 'end of history' marked by creative sterility and exhaustion. The proposed renewal does not entail destruction of tradition …

Pulsed River Flooding Effects On Sediment Deposition In Breton Sound Estuary, Louisiana, Katherine Wheelock Jan 2003

Pulsed River Flooding Effects On Sediment Deposition In Breton Sound Estuary, Louisiana, Katherine Wheelock

LSU Master's Theses

Louisiana's deltaic coast is a dynamic sedimentary environment made vulnerable by Mississippi River channelization, which restricts freshwater, sediment, and nutrient inputs to adjacent estuaries. Freshwater diversions now reconnect some estuaries with historic fluvial sources, like Breton Sound basin, which receives Mississippi River suspended loads through the Caernarvon freshwater diversion. The project objectives were to quantify short-term sediment accumulation using sediment traps, evaluate sediment trap effectiveness, and compare long-term deposition using feldspar horizon markers and 210Pb dating to the annual sediment trap deposition. Magnitude and variations of sediment deposition at 14 sites were compared during an 18-month study in the upper …

Address Register Assignment For Reducing Code Size, M. Kandemir, M. J. Irwin, G. Chen, J. Ramanujam Jan 2003

Address Register Assignment For Reducing Code Size, M. Kandemir, M. J. Irwin, G. Chen, J. Ramanujam

Faculty Publications

In DSP processors, minimizing the amount of address calculations is critical for reducing code size and improving performance since studies of programs have shown that instructions that manipulate address registers constitute a significant portion of the overall instruction count (up to 55%). This work presents a compiler-based optimization strategy to reduce the code size in embedded systems. Our strategy maximizes the use of indirect addressing modes with post-increment and post-decrement capabilities available in DSP processors. These modes can be exploited by ensuring that successive references to variables access consecutive memory locations. To achieve this spatial locality, our approach uses both …

Downstream Hydraulic Geometry Relations: 1. Theoretical Development, Vijay P. Singh, Chih Ted Yang, Z. Q. Deng

Faculty Publications

In this study, it is hypothesized that (1) the spatial variation of the stream power of a channel for a given discharge is accomplished by the spatial variation in channel form (flow depth and channel width) and hydraulic variables, including energy slope, flow velocity, and friction, and (2) that the change in stream power is distributed among the changes in flow depth, channel width, flow velocity, slope, and friction, depending on the constraints (boundary conditions) the channel has to satisfy. The second hypothesis is a result of the principles of maximum entropy and minimum energy dissipation or its simplified minimum …

Perceptions Of Social Support Within The Context Of Religious Homophily: A Social Network Analysis, Sally Robicheaux Jan 2003

Perceptions Of Social Support Within The Context Of Religious Homophily: A Social Network Analysis, Sally Robicheaux

LSU Master's Theses

Recent studies have documented (1) the direct effects of social network context on perceived adequacy of social support and (2) the indirect effects of social network context, through social support, on psychological well-being. This thesis extends that research by asking how religious homophily in social networks affects individual perceptions of support and, through that, psychological well-being (depression). Results indicate that being embedded in a network with greater religious homophily increases perceived support, but this relationship holds only for instrumental support. Additionally, both instrumental and expressive support exert significant affects on psychological well-being: greater perceived adequacy of support (both instrumental and …

Stock Price Modeling And Insider Trading Theory, Jessica J. Guillory Jan 2003

Stock Price Modeling And Insider Trading Theory, Jessica J. Guillory

LSU Master's Theses

The mathematical study of stock price modeling using Brownian motion and stochastic calculus is a relatively new field. The randomness of financial markets, geometric brownian motions, martingale theory, Ito's lemma, enlarged filtrations, and Girsanov's theorem provided the motivation for a simple characterization of the concepts of stock price modeling. This work presents the theory of stochastic calculus and its use in the financial market. The problems on which we focus are the models of an investor's portfolio of stocks with and without the possibility of insider trading, opportunities for fair pricing of an option, enlarged filtrations, consumptions, and admissibility. This …

Compositional Systematics Of Deep, Low Salinity Formation Waters In The Upper Wilcox Of Southeastern Texas, Kathleen (Kt) Moran Jan 2003

Compositional Systematics Of Deep, Low Salinity Formation Waters In The Upper Wilcox Of Southeastern Texas, Kathleen (Kt) Moran

LSU Master's Theses

Overpressured Eocene Wilcox sandstones in the Newton County, Texas Sabine Tram field contain water with salinities ranging from 14 to 28 g/L. The solutes appear to fall loosely into three groups. Na, Ca, and Mg follow systematics previously known globally for saline formation waters whereby their concentrations are controlled by fluid-mineral equilibrium. Cl, Br, I, and B are conservatively diluted constituents of some saline endmember that is not solely connate marine. Potassium does not follow any known basinal systematic, and the formation water is supersaturated with respect to SiO2 by an order of magnitude. Meteoric water is not a probable …

The Effects Of Sediment Grain Size And Oil Exploration On Microbial Atp Biomass, Eric Tyson Guilbeau Jan 2003

The Effects Of Sediment Grain Size And Oil Exploration On Microbial Atp Biomass, Eric Tyson Guilbeau

LSU Master's Theses

Adenosine triphosphate (ATP) is a unique biochemical indicator of active microbial biomass and its relationship to environmental conditions. Its assay in sediments is complicated, however, by adsorptive loss to the sediment matrix and subsequent interferences in the luciferin-luciferase assay by compounds released during the extraction process. Corrections must be applied to correct for these losses and we describe a novel approach using radioactive ATP to correct for ATP adsorption. The sediment matrix also plays a significant role in determining both the magnitude of the ATP pool and the extent of the ATP adsorptive loss. Coarser sediments were found to have …

Measuring Fear Of Crime On Campus: A Study Of An Urban University, Cheryl Papa Bedenbaugh Jan 2003

Measuring Fear Of Crime On Campus: A Study Of An Urban University, Cheryl Papa Bedenbaugh

LSU Master's Theses

Since 1990, five federal laws and many state laws have been created to increase security on university campuses (Security on Campus 2000). These laws, which include provisions that require university police and administrations to accurately and openly report the school's crime statistics (Hudge 2000), have fueled an increased focus about crime committed on university campuses. The philosophy behind the open reporting laws is twofold: parents and students have the information necessary to help them make the best decisions on which college to attend, and students are armed with information so they can take necessary precautions to enhance their level of …
