Urban Tree Phenology: A Comparative Study Between New York City And Ithaca, New York., Ishwar Dhami

Graduate Theses, Dissertations, and Problem Reports (ETD)

Studies on phenology have demonstrated that "Global warming" effect is influencing vegetation phenological processes. In order to accurately predict how climate warming affects vegetation phenology, a clear understanding of vegetation phenology and its relationship to temperature is needed. Although finding the effects of global warming on phenology across larger areas is difficult, heat island phenomena associated with urbanized area presents a unique place to investigate the local effect of warming on phenology. Thus, this study looked at the response of trees to increasing temperatures by comparing the phenological patterns of trees in a highly urbanized New York City (NYC) and …

Cultural Assimilation, Appropriation And Commercialization: Authenticity In Rap Music, 1997-2004., Jonathan P. Tummons

Graduate Theses, Dissertations, and Problem Reports (ETD)

This thesis examines the changes in authenticity in rap lyrics between 1997 and 2004. Throughout its American history, Black music has expressed the lived experiences, the psychological realities, of Africans in diaspora and has always functioned to help create, negotiate and maintain cultural identity or “Blackness”. Within the last 20 years, rap music has undergone a tremendous amount of commercialization and appropriation by capitalistic culture industries and their largely white consumer base which has resulted in the widespread assimilation of black cultural expression into popular (white) culture. Rap artists increasingly invoke their authenticity as a way of preserving their cultural …

Building Better Software: The Applicability Of A Professional Tool For Automating Quality Assessment And Fault Detection., Justin S. Di Stefano

Graduate Theses, Dissertations, and Problem Reports (ETD)

The size of software applications is growing. It is no longer possible to achieve full coverage in pre-release testing, and in many cases it is not even possible to provide significant partial coverage. Automatic methods such as formal modeling are a possible solution, but they are far too expensive to apply to every piece of developed code. Static code defect detectors provide a solid and dependable means for selecting high risk sections of code for more expensive review, such as formal modeling or manual inspection. Historically, static code defect detectors have been vilified in academic and industrial domains on the …


The Development Of A Portable Instrumented Indentation System., Jared Michael Tannenbaum Jan 2008

The Development Of A Portable Instrumented Indentation System., Jared Michael Tannenbaum

Graduate Theses, Dissertations, and Problem Reports (ETD)

Recently, considerable interest in material characterization of thin film systems and small volumes has led to the increased use of instrumented indentation. Capable of providing a material’s hardness and elastic modulus value, many consider instrumented indentation to be a non destructive testing technique. Traditionally, the indentation contact area is calculated based on the known indenter geometry and depth of penetration. This technique employs the use of high precision depth sensors which account for much of the cost associated with instrumented indentation systems. A multiple partial unloading technique needs no such sensor, as the indentation depth itself is not needed. A …

Which: A Stochastic Best-First Search Learner., Zachery A. Milton Jan 2008

Which: A Stochastic Best-First Search Learner., Zachery A. Milton

Graduate Theses, Dissertations, and Problem Reports (ETD)

Rule-based learners search a version space of combinations of features. Starting at “false”, features can be added using disjunctions, conjunctions and negations which can combine to some top-most “true” node that covers all possible examples. A complete search of all possible combinations can be too slow, due to the size of the space, or too error prone, due to noise in the space. When complete search fails, stochastic search may be a useful alternative. For example, the TAR3 “treatment learner” is a stochastic rule learner that leaps around random parts of the version space. TAR favors the construction of tiny …

Focal Adhesion Kinase Mediates Caveolin-1 Expression During Epithelial To Mesenchymal Transition: A Novel Pathway Regulating Aspects Of Cell Motility In Cancer., Kelly M. Bailey Jan 2008

Focal Adhesion Kinase Mediates Caveolin-1 Expression During Epithelial To Mesenchymal Transition: A Novel Pathway Regulating Aspects Of Cell Motility In Cancer., Kelly M. Bailey

Graduate Theses, Dissertations, and Problem Reports (ETD)

Caveolin-1, the protein coat of caveolae membrane invaginations, was originally hypothesized to function solely as a tumor suppressor in human cancers. However, since the early 1990s, caveolin-1 has been found to be up-regulated in a number of metastatic cancers. This expression has been shown to correlate with disease progression and decreases in overall patient survival in some tumor types. Further, caveolin-1 expression is elevated in multi-drug resistant cancer cells and caveolae are thought to participate in the efflux pathway to pump drugs out of these tumor cells. The overall goal of these studies was to examine changes in and regulation …

The probe measures reflected light from a particle medium which is converted into a voltage. Development of this new method yields two valuable solid flow parameters from a single probe system. The method involves a formulated model with empirical calibrations and three physical bases. The three physical bases are the Conservation Law, Beer-Lambert's Law, and the reflected light intensity from the particle medium. A novel bed depth calibration …


User Habitation In Keystroke Dynamics Based Authentication, Qi Cheng Dec 2007

User Habitation In Keystroke Dynamics Based Authentication, Qi Cheng

Graduate Theses, Dissertations, and Problem Reports (ETD)

Most computer systems use usernames and passwords for authentication and access control. For long, password security has been framed as a tradeoff between user experience and password security. Trading off one for the other appears to be an inevitable dilemma for single password based security applications. As a new biometric for authenticating access, keystroke dynamics offers great promises in hardening the password mechanism. Our research first investigate the keystroke dynamics based password security by conducting an incremental study on user's habituation process for keystroke dynamics analysis using two distinct types of passwords. The study shows that (1) long and complex …

Use Of Native Seed Mixtures To Improve Erosion Control And Wildlife Habitat On Log Landings Following Timber Harvest In The Upper Elk Watershed Of West Virginia, Lisa R. Tager

Graduate Theses, Dissertations, and Problem Reports (ETD)

Foresters in West Virginia follow BMP guidelines by reseeding retired log landings with inexpensive grasses that quickly provide erosion control. However, these grasses typically are not native nor do they provide high quality forage for wildlife. I developed 3 native seed mixtures for log landing reclamation that would maintain sediment control, as well as enhance wildlife habitat. These mixtures included an erosion control mixture, a wildlife mixture, and a wildflower mixture. I assessed sediment control, biomass production, vegetation structure, forage quality, and small mammal usage of my native mixtures and a commonly used, nonnative traditional mixture in 2005 and 2006. …

Video applications ranging from multimedia communication to computer vision have been extensively studied in the past decades. However, the emergence of new applications continues to raise questions that are only partially answered by existing techniques. This thesis studies three selected topics related to video: intra prediction in block-based video coding, pedestrian detection and tracking in infrared imagery, and multi-view video alignment.;In the state-of-art video coding standard H.264/AVC, intra prediction is defined on the hierarchical quad-tree based block partitioning structure which fails to exploit the geometric constraint of edges. We propose a geometry-adaptive block partitioning structure and a new intra prediction …


Choice Among Stimuli In Equivalence Classes, Christina Alligood Dec 2007

Choice Among Stimuli In Equivalence Classes, Christina Alligood

Graduate Theses, Dissertations, and Problem Reports (ETD)

Stability in responding to stimuli within equivalence classes has implications for the maintenance of classes and the ease at which they can be reformed. One way of investigating stability is to examine accuracy and speed of responding as a function of nodal number, or the number of nodes between stimuli in a class. Previous research suggests that subjects respond more quickly and more accurately on relations involving fewer nodes (Fields, Adams, & Verhave, 1989 [May]; Fields, Adams, Verhave, & Newman, 1990; Fields, Adams, & Verhave, 1993; Fields, Landon-Jiminez, Buffington, & Adams, 1995; Spencer & Chase, 1996). A second way to …

Comparative Study In Stereographic Reading, Alberto E. Santiago Dec 2007

Comparative Study In Stereographic Reading, Alberto E. Santiago

Graduate Theses, Dissertations, and Problem Reports (ETD)

Viewing a Single Image Random Dot Stereogram (SIRDS) or autostereogram picture requires careful concentration from the viewer. The concentration necessary to perceive depth may affect the performance of the reading process. We are studying if information perceived by way of a stereogram is better retained in memory compared to normal reading without stereo vision. To measure subject's memory performance we administered a questionnaire after a stereographic experience containing a readable story. We discovered that exposing subjects to stereographic information has a slight advantage on the ability to remember precise details of the information read.
