In Praise Of The Catenary, Fred Behroozi

Faculty Work

When a chain hangs loosely from its end points, it takes the familiar form known as the catenary. Power lines, clothes lines, and chain links are familiar examples of the catenary in everyday life. Nevertheless, the subject is conspicuously absent from current introductory physics and calculus courses.1 Even in upper-level physics and math courses, the catenary equation is usually introduced as an example of hyperbolic functions or discussed as an application of the calculus of variations. We present a new derivation of the catenary equation that is suitable for introductory physics and mathematics courses.

Fish Consciousness, David Gamez

Animal Sentience

Woodruff makes two arguments to support his claim that ray-finned fish are conscious: (1) Fish neuroanatomy has similarities with the structures in the human brain that support consciousness. (2) The complexity and flexibility of fish behaviour suggest that they are conscious. This commentary will argue that neither the neuroanatomical nor the behavioural argument can provide conclusive evidence for consciousness in fish. We should suspend judgement until we have discovered mathematical theories of consciousness that can reliably map between states of consciousness and states of the physical world.

An Investigation Of Atomic Structures Derived From X-Ray Crystallography And Cryo-Electron Microscopy Using Distal Blocks Of Side-Chains, Lin Chen, Jing He, Salim Sazzed, Rayshawn Walker

Computer Science Faculty Publications

Cryo-electron microscopy (cryo-EM) is a structure determination method for large molecular complexes. As more and more atomic structures are determined using this technique, it is becoming possible to perform statistical characterization of side-chain conformations. Two data sets were involved to characterize block lengths for each of the 18 types of amino acids. One set contains 9131 structures resolved using X-ray crystallography from density maps with better than or equal to 1.5 Å resolutions, and the other contains 237 protein structures derived from cryo-EM density maps with 2-4 Å resolutions. The results show that the normalized probability density function of block …

The Rhythmic, Harmonic And Phrasing Language Of Lennie Tristano: Analysis And Strategies For Incorporation In Modern Jazz Improvisation, Austin Salisbury

Theses : Honours

Pianist Lennie Tristano is regarded as one of the most original voices in jazz history. His uncompromising adherence to artistic ideals led to both great innovation and obscurity, limiting his impact on future generations of musicians. Until recently, his music has been largely overlooked by musicians and academics alike. Coinciding with a revival in interest in Tristano and his music by modern jazz musicians, this dissertation seeks to investigate the transferability of several aspects of Tristano’s rhythmic, harmonic and phrasing vocabulary to modern jazz improvisation. Building upon existing literature concerning his pedagogy and musical analysis, this research emphasises Tristano’s relevance …

A Survey To Investigate The Participation Of Female Jazz-Trained Instrumentalists At Waapa And In Perth’S Professional Music Scene, Talya Valenti

Theses : Honours

Traditionally, men have dominated jazz music in terms of participation and professional acknowledgement, but even in present times, female instrumentalists remain under-represented in jazz performance and education. Various studies such as Kathleen M. McKeage’s Gender and Participation in Undergraduate Jazz Ensembles: A National Survey and Erin L. Wehr’s Understanding the Experiences of Women in Jazz: A Suggested Model, have produced statistics that illustrate the low participation of female instrumentalists in jazz, and have also provided social-psychological theories to explain why these patterns continue to prevail.

As a working jazz-trained female instrumentalist myself, I have noticed the under-representation of female jazz …

Analysing Intonation Of The Pied Butcherbird, Jean-Michel Maujean

Theses : Honours

Native to Australia, the Pied Butcherbird has been extensively studied and transcribed by previous composers, notably including Olivier Messiaen. This may be due to richness and diversity in each bird’s repertoire, along with parallels drawn from Western Tonality. Hollis Taylor has conducted extensive study in this field, notably with an analysis of a transcription made by Messiaen, that was incorporated in his piece Éclairs sur l'au- delà (1988-91). Coupled with the original field recording, Taylor’s analysis and Messiaen’s score, this study will reanalyse the original recording from which Messiaen made his transcription.

Utilizing Hypervisor To Enhance Trustzone’S Introspection Capabilities On Non-Secure World, Zhang-Kai Zhang, Zhou-Jun Li, Chun-He Xia, Jin-Xin Ma, Jinhua Cui

Research Collection School Of Computing and Information Systems

Widely used on the Android phones, the technology of ARM TrustZone divides the hardware resources of Android phones into two worlds:non-secure world and secure world. The Android operating system used by user is running in the non-secure world, while the non-secure world's introspection systems (e.g., KNOX, Hypervisor) that are based on TrustZone are running in the secure world. These introspection systems have the high privilege. They can dynamically check Android kernel integrity and perform memory management of non-secure world instead of Android kernel. But TrustZonecan can not completely introspect the hardware resources (e.g., Cache) of non-secure world because of the …

Multi-Target Deep Neural Networks: Theoretical Analysis And Implementation, Zeng Zeng, Nanying Liang, Xulei Yang, Steven C. H. Hoi

Research Collection School Of Computing and Information Systems

In this work, we propose a novel deep neural network referred to as Multi-Target Deep Neural Network (MT-DNN). We theoretically prove that different stable target models with shared learning paths are stable and can achieve optimal solutions respectively. Based on GoogleNet, we design a single model with three different targets, one for classification, one for regression, and one for masks that is composed of 256  ×  256 sub-models. Unlike bounding boxes used in ImageNet, our single model can draw the shapes of target objects, and in the meanwhile, classify the objects and calculate their sizes. We validate our single MT-DNN …

Bimetallic Complexes: The Fundamental Aspects Of Metal-Metal Interactions, Ligand Sterics And Application, Michael Bernard Pastor

University of the Pacific Theses and Dissertations

Metal containing complexes have been used to catalyze various organic transformations for the past few decades. The success of several mononuclear catalysts led to transition metal catalysts used in pharmaceuticals, environmental, and industrial processes. While mononuclear complexes have been used extensively, bimetallic systems have received far less attention. Bimetallic or polynuclear sites are commonly found in metalloenzymes that perform elegant transformation in biological systems, underlying their significance. Inorganic chemists take inspiration from nature and design model bimetallic complexes to further study this cooperativity effect. A bimetallic platform offers many structural and functional differences such as the identity of the metal …

West Meets East: An Exploration Of The Ways American University Development Officers Can Build Guanxi With Chinese Parents, Jinrui Zhang Mone

University of the Pacific Theses and Dissertations

Because philanthropic support from alumni and their families is an important source of revenue for American colleges and universities, identifying ways to connect with Chinese students and cultivate philanthropic support from their parents is an essential component of fundraising efforts. In this study, I explored how American university advancement officers could employ guanxi to cultivate relationships with Chinese parent donors in order to increase U.S. higher education philanthropy efforts. The concept of guanxi, an important aspect of building and sustaining relationships in China, served as the focus for understanding Chinese parents’ connections with their children’s American universities. I employed …

[Introduction To] Finite Blaschke Products And Their Connections, Stephan Ramon Garcia, Javad Mashreghi, William T. Ross

Bookshelf

This monograph offers an introduction to finite Blaschke products and their connections to complex analysis, linear algebra, operator theory, matrix analysis, and other fields. Old favorites such as the Carathéodory approximation and the Pick interpolation theorems are featured, as are many topics that have never received a modern treatment, such as the Bohr radius and Ritt's theorem on decomposability. Deep connections to hyperbolic geometry are explored, as are the mapping properties, zeros, residues, and critical points of finite Blaschke products. In addition, model spaces, rational functions with real boundary values, spectral mapping properties of the numerical range, and the Darlington …

W1,P Regularity Of Eigenfunctions For The Mixed Problem With Nonhomogeneous Neumann Data, Kohei Miyazaki

Murray State Theses and Dissertations

We consider an eigenvalue problem with a mixed boundary condition, where a second-order differential operator is given in divergence form and satisfies a uniform ellipticity condition. We show that if a function u in the Sobolev space W^1,p_D is a weak solution to the eigenvalue problem, then u also belongs to W^1,p_D for some p>2. To do so, we show a reverse Hölder inequality for the gradient of u. The decomposition of the boundary is assumed to be such that we get both Poincaré and Sobolev-type inequalities up to the boundary.

Engineering Retention: Improving Inclusion And Diversity In Engineering, Sidney Martin

Murray State Theses and Dissertations

The researcher sought further understanding for strategies and pedagogies employed to serve the diverse learning and engagement needs of underrepresented minorities (URMs) enrolled in academic engineering programs. The researcher defined for this study underrepresented minorities as women, Hispanic Americans, and African Americans. There is a need for increased representation of URMs in both postsecondary education and the engineering profession. Underrepresented minorities are needed in the engineering profession to contribute to the complete solution and to provide improved ideas for consideration during the design process. The researcher discovered six factors utilized by engineering faculty and academic affairs in postsecondary education to …

Reframing The Proportionality Principle, Michael A. Newton

Vanderbilt Journal of Transnational Law

Proportionality functions as one of the most important legal constraints applicable to the conduct of hostilities. In that context, this short essay discusses the commonly encountered misapplications of Cicero's classic sentiment that "salus populwe supremus est lex...silent enim leges inter armes." Rather than serving as a necessary basis for a positive articulation of lawful force as an exception to the norm, jus in bello proportionality delineates the outer boundaries of the commander's appropriate discretion. The mere invocation of jus in bello proportionality cannot become an effective extension of asymmetric combat power by artificially crippling combatant capabilities. This essay ends by …

205.3 The Many Shapes Of Archive-It, Shawn Jones, Michael L. Nelson, Alexander Nwala, Michele C. Weigle

Computer Science Faculty Publications

Web archives, a key area of digital preservation, meet the needs of journalists, social scientists, historians, and government organizations. The use cases for these groups often require that they guide the archiving process themselves, selecting their own original resources, or seeds, and creating their own web archive collections. We focus on the collections within Archive-It, a subscription service started by the Internet Archive in 2005 for the purpose of allowing organizations to create their own collections of archived web pages, or mementos. Understanding these collections could be done via their user-supplied metadata or via text analysis, but the metadata is …

A Survey Of Archival Replay Banners, Sawood Alam, Mat Kelly, Michele C. Weigle, Michael L. Nelson

Computer Science Faculty Publications

We surveyed various archival systems to compare and contrast different techniques used to implement an archival replay banner. We found that inline plain HTML injection is the most common approach, but prone to style conflicts. Iframe-based banners are also very common and while they do not have style conflicts, they suffer from screen real estate wastage and limited design choices. Custom Elements-based banners are promising, but due to being a new web standard, these are not yet widely deployed.

Client-Assisted Memento Aggregation Using The Prefer Header, Mat Kelly, Sawood Alam, Michael L. Nelson, Michele C. Weigle

Computer Science Faculty Publications

[First paragraph] Preservation of the Web ensures that future generations have a picture of how the web was. Web archives like Internet Archive's Wayback Machine, WebCite, and archive.is allow individuals to submit URIs to be archived, but the captures they preserve then reside at the archives. Traversing these captures in time as preserved by multiple archive sources (using Memento [8]) provides a more comprehensive picture of the past Web than relying on a single archive. Some content on the Web, such as content behind authentication, may be unsuitable or inaccessible for preservation by these organizations. Furthermore, this content may be …

Swimming In A Sea Of Javascript Or: How I Learned To Stop Worrying And Love High-Fidelity Replay, John A. Berlin, Michael L. Nelson, Michele C. Weigle

Computer Science Faculty Publications

[First paragraph] Preserving and replaying modern web pages in high-fidelity has become an increasingly difficult task due to the increased usage of JavaScript. Reliance on server-side rewriting alone results in live-leakage and or the inability to replay a page due to the preserved JavaScript performing an action not permissible from the archive. The current state-of-the-art high fidelity archival preservation and replay solutions rely on handcrafted client-side URL rewriting libraries specifically tailored for the archive, namely Webrecoder's and Pywb's wombat.js [12]. Web archives not utilizing client-side rewriting rely on server-side rewriting that misses URLs used in a manner not accounted for …

Anatomy Of An Interrupted Irrigation Season: Micro-Drought At The Wind River Indian Reservation, Shannon M. Mcneeley, Cadida F. Dewes, Crystal J. Stiles, Tyler A. Beeton, Imtiaz Rangwala, Michael T. Hobbins, Cody L. Knutson

School of Natural Resources: Faculty Publications

Drought is a complex phenomenon manifested through interactions between biophysical and social factors. At the Wind River Indian Reservation (WRIR) in west-central Wyoming, water shortages have become increasingly common since the turn of the 21st century. Here we discuss the 2015 water year as an exemplar year, which was characterized by wetter-than-normal conditions across the reservation and, according to the U.S. Drought Monitor, remained drought-free throughout the year. Yet parts of the reservation experienced harmful water shortages, or “microdrought” conditions, during the growing season in 2015. In this assessment of the 2015 water year at the WRIR we: (1) describe …

It Is Hard To Compute Fixity On Archived Web Pages, Mohamed Aturban, Michael L. Nelson, Michele C. Weigle

Computer Science Faculty Publications

[Introduction] Checking fixity in web archives is performed to ensure archived resources, or mementos (denoted by URI-M) have remained unaltered since when they were captured. The final report of the PREMIS Working Group [2] defines information used for fixity as "information used to verify whether an object has been altered in an undocumented or unauthorized way." The common technique for checking fixity is to generate a current hash value (i.e., a message digest or a checksum) for a file using a cryptographic hash function (e.g., SHA-256) and compare it to the hash value generated originally. If they have different hash …

Privacy In Iot Cloud, Aftab Ahmad, Ravi Mukkamala, Karthik Navuluri

Computer Science Faculty Publications

We present a framework for privacy preservation in an information cloud of IoT devices. We contend that privacy provisioning should be located in the user device and must protect the user, the information, and the device from breaches in privacy. We elaborate on how the layered privacy model can ensure such privacy provisioning, and justify the device being the provisioning point instead of the cloud alone. We present the point of view that, due to resource limitations of the IoT devices in general, the privacy preserving measures need to be hard-coded in the device technology. We fall short of suggesting …

Synthesis And Applications Of Dialdehydes, Krystal Dawn Grieger

Chemistry and Biochemistry

Due to their reactivity and ease of functional group interconversions, aldehydes have wide-ranging applications in polymer synthesis, such as polyacetals, epoxy resins, and polyurethanes. Recently, room temperature synthesis of polycarbamates using cyclohexanedicarboxaldehydes was reported by Dow Chemical, thus opening up a novel way of making non-isocyanate polyurethanes (NIPUs) with greater applicability. However, preparing NIPUs is limited by the available bio-based dialdehydes. Therefore, we prepared a series of bio-derived bis-furan and tris-furan dialdehydes through the condensation of furan with four readily available ketones, with subsequent formylation via the Vilsmeier-Haack reaction. The incorporation of structurally different spacers in otherwise structurally similar dialdehyde …
