1/F Baseband Noise Suppression in Ofdm Using Kalman Filter

1/F Baseband Noise Suppression in Ofdm Using Kalman Filter

Date: May 2012
Creator: Rodda, Lasya
Description: As the technology is advances the reduced size of hardware gives rise to an additive 1/f baseband noise. This additive 1/f noise is a system noise generated due to miniaturization of hardware and affects the lower frequencies. Though 1/f noise does not show much effect in wide band channels because of its nature to affect only certain frequencies, 1/f noise becomes a prominent in OFDM communication systems where narrow band channels are used. in this thesis, I study the effects of 1/f noise on the OFDM systems and implement algorithms for estimation and suppression of the noise using Kalman filter. Suppression of the noise is achieved by subtracting the estimated noise from the received noise. I show that the performance of the system is considerably improved by applying the 1/f noise suppression.

9-Lipoxygenase Oxylipin Pathway in Plant Response to Biotic Stress

9-Lipoxygenase Oxylipin Pathway in Plant Response to Biotic Stress

Access: Use of this item is restricted to the UNT Community.
Date: May 2012
Creator: Nalam, Vamsi J.
Description: The activity of plant 9-lipoxygenases (LOXs) influences the outcome of Arabidopsis thaliana interaction with pathogen and insects. Evidence provided here indicates that in Arabidopsis, 9-LOXs facilitate infestation by Myzus persicae, commonly known as the green peach aphid (GPA), a sap-sucking insect, and infection by the fungal pathogen Fusarium graminearum. in comparison to the wild-type plant, lox5 mutants, which are deficient in a 9-lipoxygenase, GPA population was smaller and the insect spent less time feeding from sieve elements and xylem, thus resulting in reduced water content and fecundity of GPA. LOX5 expression is induced rapidly in roots of GPA-infested plants. This increase in LOX5 expression is paralleled by an increase in LOX5-synthesized oxylipins in the root and petiole exudates of GPA-infested plants. Micrografting experiments demonstrated that GPA population size was smaller on plants in which the roots were of the lox5 mutant genotype. Exogenous treatment of lox5 mutant roots with 9-hydroxyoctadecanoic acid restored water content and population size of GPA on lox5 mutants. Together, these results suggest that LOX5 genotype in roots is critical for facilitating insect infestation of Arabidopsis. in Arabidopsis, 9-LOX function is also required for facilitating infection by F. graminearum, which is a leading cause of Fusarium head ...

100% Renewable Energy - and Beyond - for Cities

100% Renewable Energy - and Beyond - for Cities

Date: March 2010
Creator: Droege, Peter
Description: This booklet sketches out the options and the processes that have started to transform urban energy systems. The document promotes carbon neutrality for communities and cities and argues that even the largest cities can make this transition, drawing on renewable energy supplies from within their boundaries, as well as from farther away. In addition to assuring urban energy security, these developments can also stimulate the growth of a very large new green economy sector.

161 Glass: Site Specific Music in an Artistic Context

161 Glass: Site Specific Music in an Artistic Context

Date: May 2010
Creator: Rusnak, Christina S.
Description: The composition 161 Glass is a 17-minute musical work with percussion, wind and brass instruments in which the intersection of mid-century architecture, and the art and culture of a dynamic city are inextricably linked. Through this paper, I explore the process of composing a musical work in relationship to the significance of site specific context. The paper begins by defining the concept of site specific art works; then reviews the discourse of the intersection of art, music and architecture. I then delve into the cultural and geographic context surrounding this project from the modern era through the present, and how those perspectives apply to the building and my piece. I reveal how the composition relates the musical ideas to the site. Finally, I describe the collaborative process between myself, the musicians and the Dallas Contemporary staff.

A 018μm Cmos Transmitter for Ecg Signals

A 018μm Cmos Transmitter for Ecg Signals

Date: December 2013
Creator: Kakarna, Tejaswi
Description: Electrocardiography (ECG) signal transmitter is the device used to transmit the electrical signals of the heart to the remote machine. These electrical signals are ECG signals caused due to electrical activities in the heart. ECG signals have very low amplitude and frequency; hence amplification of the signals is needed to strengthen the signal. Conversion of the amplified signal into digital information and transmitting that information without losing any data is the key. This information is further used in monitoring the heart.

2010 Forest Carbon Workgroup: Final Report

2010 Forest Carbon Workgroup: Final Report

Date: January 2011
Creator: Partridge, Craig; Boese, Jerry & Bernath, Stephen
Description: This document provides a detailed report and recommendations of the 2010 Forest Carbon Work group to the Director of the Department of Ecology and the Commissioner of Public Lands. The recommendations relate to the critical role Washington’s forest lands will play in addressing the challenge of climate change; appropriate responses to pressure for conversion of working forest lands to non-forest uses; and the role of ecosystem service markets, including carbon offset markets, and other incentive systems in bringing about desired results. The 2010 Work group included some members of a similar 2008 Work group and built on the results of that 2008 effort. The report appendix contains purpose statements by each participating interest, explaining its rationale for participation. In light of the 2010 Work group emphasis, this document focused on three topics: Forest carbon considerations in avoiding forest land use conversion; incentives to reward forest landowners for providing ecosystem services, including carbon storage and improvement of forest health; and features of forest carbon offset protocols and registries that are appropriate for use by forest offset project developers in Washington State.
