Entropic Characterization Of Mixing In Microchannels, Marco Camesasca, Ica Manas Zloczower, Miron Kaufman

Physics Faculty Publications

A methodology for rigorous mixing assessment in microchannels is presented. The analysis is based on numerical simulations of flow in different geometries coupled with mixing assessment using entropic measures. The results show enhanced mixing efficiency for the staggered herringbone micromixer by comparison with a mixer with straight diagonal ridges and a lack of mixing in a non-patterned channel. These results are in agreement with published experimental data.

Total Syntheses Of (+)-Geldanamycin, (-)-Ragaglitazar, And (+)-Kurasoin A And Phase-Transfer-Catalyzed Asymmetric Alkylation, Erik J. Hicken

Theses and Dissertations

Geldanamycin possesses various biological activities as seen in the NCI 60 cell line panel (13 nM avg., 70 nM SKBr-3 cells). The predominant mode of action providing these unique results arises from the ability of geldanamycin (GA) to bind to the chaperone heat shock protein 90 (Hsp90). Despite its complicated functionality, the first total synthesis of GA was accomplished, which included two new reactions developed specifically to address the stereochemical features. The final step in the synthesis of GA was a demethylation-oxidation sequence to generate the desired para-quinone. This step could only be accomplished with HNO3/AcOH, producing GA in …

Efficient Xquery Processing Of Streamed Xml Fragments, Seo Young Ahn

Computer Science and Engineering Theses - Archive

XStreamCast is a push-based streamed XML query processing system that supports multiple servers and clients. The servers broadcast streamed XML data while the clients register to these servers for a specific service and process streamed XML fragments. This thesis presents methods for efficient XQuery processing of streamed XML fragments for the client. The XQuery parser parses the XQuery given by the user first. The client processes the fragments and stores only the needed data for the query. The query is then applied to stored XML fragments. This system can be valuable for managing the memory of the client because it …

The First-Optical-Vla Survey For Lensed Radio Lobes, Deborah B. Haarsma, Joshua N. Winn, Emilio E. Falco, Christopher S. Kochanek

University Faculty Publications and Creative Works

We present results from a survey for gravitationally lensed radio lobes. Lensed lobes are a potentially richer source of information about galaxy mass distributions than lensed point sources, which have been the exclusive focus of other recent surveys. Our approach is to identify radio lobes in the Faint Images of the Radio Sky at Twenty cm (FIRST) catalog and then search optical catalogs for coincident foreground galaxies, which are candidate lensing galaxies. We then obtain higher resolution images of these targets at both optical and radio wavelengths and obtain optical spectra for the most promising candidates. We present maps of …

Supramolecular Chemistry Of Nitrogen Dioxide, Yanlong Kang

Chemistry & Biochemistry Dissertations - Archive

Supramolecular chemistry has been defined as "chemistry beyond molecules", and involves investigating molecular systems held together reversibly by inter-molecular forces, not by covalent bonds. This dissertation discusses a supramolecular approach towards sensing, entrapment and utilization of NO2/N2O4 gases. Chapter 1 briefly discusses supramolecular chemistry and supramolecular chemistry of gases. In chapter 2, the interaction of NOx with metalloporphyrins is described. Specifically, ruthenium nitrosyl derivatives hold a special place in mimicking bio-relevant NO-metal interactions. A previously unnoticed reaction between NO2/N2O4 and a Ru(II) porphyrin is described. It causes disproportionation of N2O4 and leads to a stable nitrosyl nitrato complex. Our findings …

A Novel Game Theoretic Framework For Security In Wireless Sensor Networks, Afrand Agah

Computer Science and Engineering Dissertations - Archive

Due to severe resource limitations and often lack of centralized infrastructure, providing security in wireless sensor networks is a great challenge. Misbehavior due to malicious or faulty nodes can significantly degrade the performance of such networks. Therefore, countermeasures against denial of service (DoS) attacks and node misbehavior are essential requirements. We argue that the conventional view of security based on cryptography techniques is not sufficient for securing wireless sensor networks. In this dissertation, we investigate a novel framework by proposing three approaches for security enforcement in such networks that range from prevention of DoS attacks to secure routing. Prevention of …

Geometrical Problems In Engineering Mechanics, Feraydune Kashefi, Mostafa Ghandehari

Mathematics Technical Papers - Archive

Four problems in two dimensional geometry are presented, which are applicable to education of the basic courses, statics. These problems represent geometrical concepts that are understandable by engineering students. For example, consider a triangle made from a uniform rod. If we draw the inscribed circle of this triangle, and concentrate the weight of each side on the point at which in circle touches the side, center of the gravity of the three concentrated masses is located at the center.

Microarray technology has rapidly taken a key position among bioinformatics research tools. After the completion of the Human Genome Project, microarray databases have become particularly important to the management and analysis of genomic data. These databases are ideal tools for many research areas involving gene expression patterns under different experimental conditions. This work attempts to assess the querying capabilities of current public microarray database implementations by evaluating their data management, query interfaces, and results presentation. We are not aware of any comparative study available to date that evaluates this important class of biological databases. We examine and evaluate how several …

Repclass: Cluster And Grid Enabled Automatic Classification Of Transposable Elements Identified De Novo In Genome Sequences, Nirmal Ranganathan

Computer Science and Engineering Theses - Archive

In the last few years many computer and laboratory improvements in the production and analysis of DNA sequences have made possible the complete sequencing of whole genomes. This provides us with a wealth of raw genomes that needs to be processed and annotated. 5% to 80% of eukaryotic genomes contain repetitive DNA consisting of transposable elements and tandem repeats which needs to be identified, classified and annotated in order to sequence and annotate the entire genome accurately. Existing tools allow us to identify and annotate transposable elements (TE) but no tool exists for their classification. This thesis work introduces REPCLASS …

Application Of Graph-Based Data Mining To Biological Networks, Chang Hun You

Computer Science and Engineering Theses - Archive

A huge amount of biological data has been generated by long-term research. It is time to start to focus on a system-level understanding of bio-systems. Biological networks are networks of biochemical reactions, containing various objects and their relationships. Understanding of biological networks is a starting point of systems biology. Multi-relational data mining finds the relational patterns in both the entity attributes and relations in the data. A widely used representation for relational data is a graph consisting of vertices and edges between these vertices. Graph-based data mining, as one approach of multi-relational data mining, finds relational patterns in a graph …

Adaptive Agent Communities For Providing Services In Dynamic Networks, Nayantara Mallesh

Computer Science and Engineering Theses - Archive

New network applications are being created everyday to accommodate diverse user needs. Delivering services to the user in a timely manner taking into account network conditions, resources allocated and network load is a challenge. Multiprotocol Label Switching attempts to overcome best-effort service by providing a method for routing traffic around network congestion, resource reservation and quality of service (QoS) capabilities. IntServ and DiffServ are two other QoS models in use today. IntServ provides per-flow guarantee of quality while DiffServ is based on aggregate service classes. Adaptive Network Service (ANS) is a community of adaptive, collaborating agents residing in the network …

Multi-Dimensional Indexing For Xml Data, Do Youn Kim

Computer Science and Engineering Theses - Archive

The Extensible Markup Language (XML) is becoming a dominant standard for exchanging and retrieving data over the internet. As XML in data exchanging grows, various XML indexing techniques have been proposed for fast and efficient query processing. A survey of theses techniques [9] categorized them into sequence-based indexes, structural indexes, dimension-based indexes and keyword-based indexes based on their properties. In this thesis, we focus on the multi-dimensional XML indexing; more precisely, it can be categorized as a 2-dimension based indexing, which is used in this paper. We studied the properties of multi-dimensional XML indexing and created an implementation to evaluate …

Adaptive, Multimodal, Application Independent User Interfaces For People With Disabilites Using Computers, Padmapriya Sambath

Computer Science and Engineering Theses - Archive

The goal of this thesis is to create more adaptive and flexible user interfaces for people with disabilities and presenting information to everyone and on every device at any time. Delivering information at any time leads to situations such as a person walking with a mobile device having a small screen wanting to make a flight reservation. The intention of presenting information to everybody immediately raises the question of how much of the available information reach people with disabilities. We have suggested a content based user interface language that may be used by external services to interact with the user. …

Service Discovery By Automated Structural And Semantic Matching, Alan Walker

Computer Science and Engineering Theses - Archive

Pervasive computing systems need to locate and use services dynamically. Current models of service location and interaction rely on a fixed contract, or service description, located by name and/or a combination of keywords. This implies a priori agreement on the service description, leading to fragility and the inability for systems to interoperate unless they were built to match an existing standard. This thesis implements a technique for relaxing the fixed contract assumption, so that the nearest match amongst a set of services can be located. The system takes into account structural, data type and naming differences. The naming differences are …

Supramolecular Nanostructures Based On Calixarenes, Heng Xu

Chemistry & Biochemistry Dissertations - Archive

This dissertation describes a systematic approach towards the design, synthesis, characterization, and application of calixarene-based supramolecular nanostructures. Chapter 1 briefly overviews the field of supramolecular chemistry and highlights its horizons. Chapter 2 introduces a modular strategy towards synthesis of nanoscale receptor macromolecules--calix-peptide conjugates. This strategy combines the unique host-guest capabilities of calixarene chemistry with synthetically flexible peptide synthesis. A series of calixarene amino acids was prepared and further utilized to synthesize calixarene dipeptides. Through this approach, calixarene amino acids are now available to be incorporated into peptide networks and nanostructured biologically relevant materials. Chapter 3 demonstrates supramolecular applications of calixarene-peptide …

Evidence For Native-Defect Donors In N-Type Zno, David C. Look, Gary C. Farlow, Pakpoom Reunchan, Sukit Limpijumnong, S. B. Zhang, K. Nordlund

Physics Faculty Publications

Recent theory has found that native defects such as the O vacancy V_O and Zn interstitial Zn_I have high formation energies in n-type ZnO and, thus, are not important donors, especially in comparison to impurities such as H. In contrast, we use both theory and experiment to show that, under N ambient, the complex Zn_I-N_O is a stronger candidate than H or any other known impurity for a 30 meV donor commonly found in bulk ZnO grown from the vapor phase. Since the Zn vacancy is also the dominant acceptor in such material, we must …
