Development Of A Suction-Controlled Resonant Column Apparatus With Self-Contained Bender Elements, Eduardo Alfonso Suescun-Florez

Civil Engineering Theses - Archive

Small-strain soil stiffness properties such as shear modulus, shear wave velocity, and material damping, are key subsoil parameters for an adequate analysis and design of unsaturated earth structures subject to static and non-static loading. Most conventional geotechnical testing techniques, however, are not able to capture this small-strain behavior and, hence, enormously underestimate the true soil stiffness, primarily due to inaccuracies in small-strain measurements. Around the world, a great deal of research efforts has been dedicated to field and laboratory based measurements of soil suction, assessments of soil-water retention properties, and analyses of swell-collapse behavior. However, very few efforts have been …

Predition Of Torque And Radial Forces In Permanent Magnet Synchronous Machines Using Field Reconstruction Method, Banharn Sutthiphornsombat

Electrical Engineering Theses - Archive

Due to their high torque-to-loss ratio, permanent magnet synchronous machines (PMSM) have received increasing attention in automotive applications over the past decade. Because of this unique characteristics, many applications have utilized PMSM. In addition to high efficiency, quiet operation of the machines is desirable in automotive, naval and military applications. In order to operate at high efficiency quietly, the torque pulsation or torque ripple needs to be monitored and mitigated accurately. Magnitude of the torque ripple is influenced by the magnetic design (cogging torque) and excitation, and the pattern of ripple is affected by the machine's geometry (stator slots).Field reconstruction …

Building Cultural Bridges Across Generational Chasms: Comparing Chicano And Jewish American Literature, Thomas Rhea Jan 2010

Building Cultural Bridges Across Generational Chasms: Comparing Chicano And Jewish American Literature, Thomas Rhea

English Theses - Archive

This study compares Arturo Islas's novel, The Rain God: A Desert Tale with Cynthia Ozick's novella, "Envy; or Yiddish in America." Specifically, I argue that during the 1970s, these authors fictionalized the discourse concerning trans-generational cultural inheritance anxiety. Islas and Ozick shared an anxiety about the future of their individual ethnic culture in America because the children born in America were moving away from the ethnic culture they inherited from their parents. Ozick and Islas's fictions question whether accepting a new American identity, as many ofthe youth in their stories do, may severely impact the continuation of their ethnic culture. …

Convert Uhf Rfid Tag From Passive To Semi-Passive Tag Using External Power Sources, Tanvi Mehta Jan 2010

Convert Uhf Rfid Tag From Passive To Semi-Passive Tag Using External Power Sources, Tanvi Mehta

Electrical Engineering Theses - Archive

In this thesis, I present novel circuit designs that convert a passive radio frequency identification (RFID) tag into a semi-passive RFID tag. Passive RFID tags are relatively inexpensive to purchase and to integrate into objects and devices. However, in some environments and on some objects the performance of the pure passive tags is not sufficient for the intended applications. A semi-passive tag, in comparison to a pure passive tag, has significantly greater communication range since the semi-passive tag derives its operational power from an on-tag power source instead of just from an interrogator's communication signal. As a result, semi-passive tags …

Optimal Output Gain Algorithm For Feed-Forward Network Training, Babu Hemanth Kumar Aswathappa Jan 2010

Optimal Output Gain Algorithm For Feed-Forward Network Training, Babu Hemanth Kumar Aswathappa

Electrical Engineering Theses - Archive

A batch training algorithm for feed-forward networks is proposed which uses Newton's method to estimate a vector of optimal scaling factors for output errors in the network. Using this vector, backpropagation is used to modify weights feeding into the hidden units. Linear equations are then solved for the network's output weights. Elements of the new method's Gauss-Newton Hessian matrix are shown to be weighted sums of elements from the total network's Hessian. The effect of output transformation on training a feed-forward network is reviewed and explained, using the concept of equivalent networks. In several examples, the new method performs better …

An Ecocritical Exploration Of The Unique Nature Of Early Modern Oceans In The Blazing World And The Tempest, Marykathryn Earnest Jan 2010

An Ecocritical Exploration Of The Unique Nature Of Early Modern Oceans In The Blazing World And The Tempest, Marykathryn Earnest

English Theses - Archive

Early modern perceptions of oceanic space diverged from standard perceptions of nature on land (or land-nature) because oceans presented a different type of wilderness. Because oceans defied early modern definitions of nature, they refused to support the developing mechanistic approach in the way that land-nature did. My argument begins with a chapter exploring science and nature in the early modern period. My second chapter expands this demonstration with an exploration of The Tempest. Shakespeare's self-reflexivity and exploration of boundaries in representing islands and oceans exemplifies their liminal position within nature. In my final chapter, I examine Margaret Cavendish's The Blazing …

Children Of Israel: Jacob Figures And Themes In The Novels Of Chaim Potok, Alan Morris Cochrum Jan 2010

Children Of Israel: Jacob Figures And Themes In The Novels Of Chaim Potok, Alan Morris Cochrum

English Theses - Archive

The twentieth-century novelist Chaim Potok made central to his fiction what he called “culture war,” juxtaposing his Jewish-American characters' inner spiritual lives with key elements of Western secularism. In five of his novels -The Promise (1969), My Name Is Asher Lev (1972), The Book of Lights (1981), Davita's Harp (1985), and The Gift of Asher Lev (1990) - the protagonist comes under the influence of a character who can be styled “the Jacob figure.” This thesis argues that these characters not only echo various aspects of the biblical narratives about the Hebrew patriarch, thereby turning him into a meta-character in …

Japan In The Mirror Of Language: The Failure Of Language To Represent Objects In Travel Narratives On Japan, Andrew Tyner Jan 2010

Japan In The Mirror Of Language: The Failure Of Language To Represent Objects In Travel Narratives On Japan, Andrew Tyner

English Theses - Archive

The travel narrative is, ostensibly, little more than representation of foreign places and things, foreign objects. The language of the travel narrative seems, on the surface, to succeed in representing the foreign. None the less, theory abounds which holds that language is fundamentally unable to represent objects, at least in a pure sense. Taking Japanese travel narratives as a particular example, this thesis attempts to demonstrate that the language of these narratives fails to successfully and fully represent objects as they exist, or have existed, in the world. I work between what I take as two extreme theories of language, …

Biography As A Searchlight: Finding The Frank Stanford Story Cycle In Ellen Gilchrist's Fiction, Alyson Ward

English Theses - Archive

Ellen Gilchrist's short stories and novels form several story cycles that connect her characters and tie her work together into interdependent story groups. Her work is also strikingly autobiographical, featuring protagonists who resemble her in obvious ways. Though critics have identified many of Gilchrist's story cycles, one important cycle has been all but ignored: a young poet appears in a number of her stories, and for several of Gilchrist's protagonists, he serves as a catalyst for needed change. The poet is a fictional representation of the poet Frank Stanford, who died in 1978 but played the same life-changing role for …

H.264 Standard Based Side Information Generation In Wyner-Ziv Coding, Subrahmanya Maira Venkatrav

Electrical Engineering Theses - Archive

The traditional video coding involves a high complexity encoder and relatively low complexity decoder. The complexity of the encoder is mainly due to motion estimation [3] and other prediction techniques employed . There is a new paradigm emerging in video coding - Distributed video coding (DVC). This is based on Slepian-Wolf and Wyner-Ziv6 theorems. In Wyner-Ziv video coding, encoder is less complex compared to the decoder. The decoder is very complex due to prediction involved for side information (SI) generation. There is lot of research done previously on linear density parity check codes (LDPC) and H.263 standard based SI generation …

Capacitive Strain Sensors For Measurement Of Large Strain For Structural Health Monitoring, Clement Jacob

Electrical Engineering Theses - Archive

Structural health monitoring (SHM) is increasingly used to replace time based management, with a more efficient Condition Based Maintenance (CBM). The traditional scheme of scheduling down time for aircraft inspection or periodic evaluation of civil infrastructure costs millions of dollars in maintenance due to either downtime or lack of timely maintenance. SHM involves periodic, real time sampling and analysis of signals, from onboard sensors like accelerometer, pressure, strain or acoustic sensors to determine the condition of the structure. This can be used to carry out immediate repairs as well as predict failure. We report the development of a new high …

A Comparison Method To Evaluate Motion Splicing Techniques, George Thekkanath Raphael Jan 2010

A Comparison Method To Evaluate Motion Splicing Techniques, George Thekkanath Raphael

Electrical Engineering Theses - Archive

The development of methods for the re-use and modification of motion data is an activearea of research. Among these methods, we find automatic techniques to generate a spliced motion by combining different actions recorded in separate sessions. Motion splicing allows capturing motion independently and later combining them to create a new natural looking motion. Even though there have been a lot of research on motion editing techniques, less focus has been given to evaluate these edited motions. In this thesis, we present a novel methodology to quantitatively evaluate the synthesized motion generated by different motion editing techniques. We implemented three …
