A Performance Guide to Luigi Nono's Post-Prae-Ludium No. 1 "Per Donau"

A Performance Guide to Luigi Nono's Post-Prae-Ludium No. 1 "Per Donau"

Date: August 2009
Creator: Tignor, Scott Edward
Description: Luigi Nono's work Post-Prae-Ludium No.1 "per Donau" represents a model for the emerging genre of electroacoustic tuba music. It is important to preserve this electroacoustic work because of its value to the tuba literature. Not only is it one of the first electroacoustic works for the tuba, but it also was composed by a man who is highly regarded in the field of music composition. Its preservation will be difficult because of the rapid advancement in technology. Within the last three decades of existence, the technology has evolved three times. An examination of the performance practice in Post-Prae-Ludium was undertaken to understand the demand on the performer required to play this work. This study will look at both non-traditional performance practices, as well as an inherent problem of how the advancement of technology can actually threaten the survival of a work dependent upon a specific version of electronic technology. Nono worked in collaboration with Giancarlo Schiaffini to compose a work for tuba and live electronics. Correspondence with Schiaffini has provided his thoughts on the collaboration of Post-Prae-Ludium with Nono and given a better understanding of how to perform the work. Technology will change, and these current adaptations of Post-Prae-Ludium may ...

FPGA Implementation of Low Density Party Check Codes Decoder

FPGA Implementation of Low Density Party Check Codes Decoder

Date: August 2009
Creator: Vijayakumar, Suresh
Description: Reliable communication over the noisy channel has become one of the major concerns in the field of digital wireless communications. The low density parity check codes (LDPC) has gained lot of attention recently because of their excellent error-correcting capacity. It was first proposed by Robert G. Gallager in 1960. LDPC codes belong to the class of linear block codes. Near capacity performance is achievable on a large collection of data transmission and storage.In my thesis I have focused on hardware implementation of (3, 6) - regular LDPC codes. A fully parallel decoder will require too high complexity of hardware realization. Partly parallel decoder has the advantage of effective compromise between decoding throughput and high hardware complexity. The decoding of the codeword follows the belief propagation alias probability propagation algorithm in log domain. A 9216 bit, (3, 6) regular LDPC code with code rate ½ was implemented on FPGA targeting Xilinx Virtex 4 XC4VLX80 device with package FF1148. This decoder achieves a maximum throughput of 82 Mbps. The entire model was designed in VHDL in the Xilinx ISE 9.2 environment.

Stimuli-responsive microgels for self-assembled crystalline structures and controlled drug release.

Stimuli-responsive microgels for self-assembled crystalline structures and controlled drug release.

Date: August 2009
Creator: Zhou, Jun
Description: Tissue response to PNIPAM and HPC nanoparticles has been studied by implantation method. The results suggest that both PNIAPM and HPC nanoparticles possess good biocompatibility and they may serve as a good carrier for the applications of controlled delivery. Rheological properties of dispersions of IPN microgels composed of PNIPAM and PAAc have been studied. It is found that the IPN microgel dispersion can undergo a sol-gel transition at temperature above 33°C. In vivo drug release experiments suggest that the gelation procedure creates a diffusion barrier and thus leads to slow release. An emulsion method has been used to grow columnar crystals by mixing PNIPAM microgel dispersions with organic solvents. Effect of both temperature and microgel concentration on formation of columnar crystals has been studied. PNIPAM-co-NMA microgels have been used for the fabrication of crystalline hydrogel films by self-crosslinking microgels. The hydrogel film exhibits an iridescent. The thermally responsive properties and mechanical properties of this film have been studied. Melting temperature (Tm) of colloidal crystals self-assembled with PNIPAM-co-AAc microgels has been investigated as a function of pH, salt concentration and microgel concentration. It is revealed that Tm increases as pH value increases; Tm decreases with increase of salt concentration; Tm increases ...

IHDP Global Carbon Cycle Research: International Carbon Research Framework

IHDP Global Carbon Cycle Research: International Carbon Research Framework

Date: February 2001
Creator: Gupta, Joeeta; Lebel, Louis; Vellinga, Pier & Young, Oran
Description: The degree to which carbon flows balance each other - human activities leading to carbon emissions into the atmosphere, vegetation and oceans soaking it up - is the subject of vigorous debate. It is not yet possible to define quantitatively the global effects of human activities such as forestry and agriculture, and may never be so. However, studies to determine these effects have emerged as critical for understanding how the earth's climate will evolve in the future. Global concern about the potential implications of the behaviour of the carbon cycle under anthropogenic stress includes concepts of system instability and large scale change. To contribute to understanding this behaviour, and our potential responses to it, requires a thorough investigation of both biophysical and social systems. Until recently, most scientific assessments of such risks focused on the anatomy of conceivable environmental changes themselves, devoting little attention to either the human driving forces or the ecosystems and societies that might be endangered by the changes. Recently, however, questions about the linkage and interaction of social, ecological, and biogeochemical systems are emerging as a central focus of policy-driven assessments of global environmental risks. The approach used here is to accept humans as an integral ...

Taiwanese Cruisers in North America: An Empirical Analysis of Their Motivations, Involvement, and Satisfaction

Taiwanese Cruisers in North America: An Empirical Analysis of Their Motivations, Involvement, and Satisfaction

Date: August 2009
Creator: Huang, Taiyi
Description: Cruise travel has become very popular worldwide. The North American cruise market is the world's biggest. Asian countries are among the fastest-growing outbound market for cruise travel. The Taiwanese cruise market has grown substantially. However, few research studies have examined Taiwanese travelers' motivation to experience a cruise vacation, and their satisfaction with the experience. Primary data was collected from a convenience sample of Taiwanese tourists who had been on North American cruise tours. Survey respondents were first time cruisers, over 40 years old, married, and had a Bachelor's degree, or higher. Push and pull motivational factors were identified. Respondents were influenced by recommendations from media and people. Respondents were satisfied with tangibles, cleanliness, food choices and selection, and responsiveness of staff. An overwhelming majority of cruisers would re-visit and recommend this trip. Implications for researchers and practitioners are suggested.

Investigating the relationship between the business performance management framework and the Malcolm Baldrige National Quality Award framework.

Date: August 2009
Creator: Hossain, Muhammad Muazzem
Description: The business performance management (BPM) framework helps an organization continuously adjust and successfully execute its strategies. BPM helps increase flexibility by providing managers with an early alert about changes and, as a result, allows faster response to such changes. The Malcolm Baldrige National Quality Award (MBNQA) framework provides a basis for self-assessment and a systems perspective for managing an organization's key processes for achieving business results. The MBNQA framework is a more comprehensive framework and encapsulates the underlying constructs in the BPM framework. The objectives of this dissertation are fourfold: (1) to validate the underlying relationships presented in the 2008 MBNQA framework, (2) to explore the MBNQA framework at the dimension level, and develop and test constructs measured at that level in a causal model, (3) to validate and create a common general framework for the business performance model by integrating the practitioner literature with basic theory including existing MBNQA theory, and (4) to integrate the BPM framework and the MBNQA framework into a new framework (BPM-MBNQA framework) that can guide organizations in their journey toward achieving and sustaining competitive and strategic advantages. The purpose of this study is to achieve these objectives by means of a combination of methodologies ...

Citizen Involvement and Law Enforcement: Does Coproduction Affect Organizational Efficiency and Organizational Effectiveness?

Citizen Involvement and Law Enforcement: Does Coproduction Affect Organizational Efficiency and Organizational Effectiveness?

Date: August 2009
Creator: Gultekin, Sebahattin
Description: Citizen involvement in the production and delivery of public service has been a long time topic of interest and controversial debate among scholars. Essentially, the belief has been that if citizens are actively involved in the process, public organizations and communities benefit in numerous ways that will ultimately lead to increased citizen satisfaction. The purpose of this research is to explore the relationship between citizen involvement in the production of public safety and security and its effects on organizational efficiency and effectiveness of law enforcement agencies. To test the assumption that citizen involvement is positively correlated to organizational success and organizational efficiency of law enforcement agencies, a citizen involvement index was developed and used as the independent variable in ordinary least square regression (OLS) analysis. Three separate models are developed to measure the impact of citizen involvement on law enforcement. Findings obtained through bivariate and multivariate analyses indicate mixed results. Bivariate analysis revealed that citizen involvement was negatively correlated to organizational efficiency while no statistically significant correlation was found in multiple regressions. In addition, through bivariate analyses, citizen involvement was positively correlated with crime rates reported to city police departments, whereas multivariate regression analyses indicated that citizen involvement does not ...

Global Environmental Change and Food Systems: Science Plan and Implementation Strategy

Global Environmental Change and Food Systems: Science Plan and Implementation Strategy

Date: 2005
Creator: Global Environmental Change and Food Systems
Description: Recent years have seen a greatly increased understanding of how global environmental change will affect crop and animal productivity and these results pave the way for broader analyses of global environmental change impacts on food production. However, there is a need to think beyond productivity and production - food security is the ultimate concern, as it is of greater relevance to societal well-being and hence policy-making. To address this broader concept of food security, research and policy formulation needs to be set within the context of food systems, rather than just food supply. This will allow a more thorough understanding of the links between food security and the environment, and make clearer where technical and policy interventions in food systems might be help them adapt to global environmental change.
