Show moreThe turbulent boundary layer is one of the most fundamental and important applications of fluid mechanics. Despite great practical interest and its direct impact on frictional drag among its many important consequences, no theory absent of significant inference or assumption exists. Numerical simulations and empirical guidance are used to produce models and adequate predictions, but even minor improvements in modeling parameters or physical understanding could translate into significant improvements in the efficiency of aerodynamic and hydrodynamic vehicles. Classically, turbulent boundary layers and fully-developed turbulent channels and pipes are considered members of the same “family,” with similar “inner” versus “outer” descriptions. However, recent advances in experiments, simulations, and data processing have questioned this, and, as a result, their fundamental physics. To address a full range of pressure gradient boundary layers, a new approach to the governing equations and physical description of wall-bounded flows is formulated, using a two variable similarity approach and many of the tools of the classical method with slight but significant variations. A new set of similarity requirements for the characteristic scales of the problem is found, and when these requirements are applied to the classical “inner” and “outer” scales, a “similarity map” is developed providing a clear prediction of what flow conditions should result in self-similar forms. An empirical model with a small number of parameters and a form reminiscent of Coles’ “wall plus wake” is developed for the streamwise Reynolds stress, and shown to fit experimental and numerical data from a number of turbulent boundary layers as well as other wall-bounded flows. It appears from this model and its scaling using the free-stream velocity that the true asymptotic form of u′2 may not become self-evident until Re ≈ 275, 000 or δ+ ≈ 105, if not higher. A perturbation expansion made possible by the novel inclusion of the scaled streamwise coordinate is used to make an excellent prediction of the shear Reynolds stress in zero pressure gradient boundary layers and channel flows, requiring only a streamwise mean velocity profile and the new similarity map. Extension to other flows is promising, though more information about the normal Reynolds stresses is needed. This expansion is further used to infer a three layer structure in the turbulent boundary layer, and modified two layer structure in fully-developed flows, by using the classical inner and logarithmic profiles to determine which portions of the boundary layer are dominated by viscosity, inertia, or turbulence. A new inner function for U+ is developed, based on the three layer description, providing a much more simplified representative form of the streamwise mean velocity nearest the wall.

Show moreIn a 2012 report, the President’s Council of Advisors in Science and Technology (PCAST) published a memorandum that calls for the identification of 1000 MHz of Federal Spectrum to be shared with private (commercial) users. This dissertation proposes a system that employs RF measurements for spectrum usage modeling and Dynamic Spectrum Access (DSA) methodologies that utilize the modeling information to permit sharing of wireless resources. A procedure called the Comprehensive Band Modeling (CBM) procedure is developed that automatically models measured RF data from any band of interest and identifies the locations of signals and holes present in the band. The output of the CBM procedure is summarized in a compact versatile format that makes DSA applications feasible. The research primarily focuses on the 450-474 MHz land mobile radio (LMR) band, and several additional bands like the TV band and the 2.5-2.7 GHz band. However, the research methodology and techniques are broadly applicable to many more frequency ranges. The research has four main areas: (a) spectrum sensor design and measurements, (b) occupancy modeling, (c) communicating the modeling information in a compact form to secondary users to support DSA algorithms and protocols, and (d) tools and metrics for spectrum sharing favorability analysis. Three spectrum sensor platforms were employed in measurements – (1) a spectrum analyzer based Spectrum Observatory (SO) that was developed earlier, (2) a specially purposed software-defined radio (SDR) for measuring LMR channels, (3) and a high-speed and portable SO system based on a sensor called the RFeye. An SO continually measures RF data in a band at a high temporal resolution such that the channel switching activity is seen – like, transmitters turning on and off. Spectrum measurements of the individual RF channels in the 450-474 MHz LMR band and the two commercial bands are used to generate statistical traffic and occupancy models. Long-term measurement data is used to assess how stationary the channel is, and how often the model parameters need to be updated. The spectrum observatory supports a network of Secondary Users (SU) by communicating the traffic model parameters in a compact format to the SUs. The SUs share Primary User (PU) channels via DSA techniques. The DSA algorithms take advantage of the model parameters provided by the SO to maximize SU throughput with limited interference on the PU. The DSA coexistence techniques are evaluated via simulation. The simulation results including Spectrum Opportunity Accessed (SOA), SU throughput, and collision rates are then analyzed to provide an assessment of DSA-based spectrum sharing in that band. The main contribution of this dissertation is the aforementioned CBM procedure. The white spaces in the frequency and time domains, that is, the underutilized spectrum opportunities available for possible secondary use via DSA are automatically identified, as well as the frequency locations that are not conducive to DSA due to the presence of frequent primary licensee transmissions. In CBM, white spaces are referred to as ‘Holes’, and the licensed primary transmission frequencies as ‘Signals’. Useful information about the duty cycles and traffic patterns of incumbent users’ activity within possible secondary use channels is extracted and modeled. The model enables prospective secondary users of white spaces to predict the expected level of interference in any channel, which allows for channel ranking and optimal selection of DSA transmission parameters. The CBM model is describable by a tiered structure, where the first tier identifies the holes and signals; the second tier ranks the holes in terms of available bandwidth and incumbent duty cycle; and the third tier models the infrequent incumbent transmissions. With the three tiers of information, an SU can readily identify all the suitable DSA channels within the entire spectrum band. This essential summary information is retrieved as a “Hole Descriptor Object” (HDO) that is both compact and tractable. Empirical spectrum measurement data obtained from the three different SO platforms is used to test the performance of the CBM procedure in the 2500-2700 MHz frequency range that currently has WiMAX deployments, the TV white space band, and the 450-474 MHz LMR band in Chicago. Spectrum measurement data runs into hundreds of megabytes or gigabytes. As such, the raw information is not very applicable in practical wireless networks. The HDO objects on the other hand are compact and only kilobytes in size. The HDO objects contain all the useful and applicable information necessary for any smart radio (primary or secondary) to select transmission parameters like frequency of operation and bandwidth, so that it can efficiently operate. Thus, the advantage of the CBM procedure is that it summarizes gigabytes of raw spectrum measurements in a usable compact format that can be directly used by practical smart radios to operate using DSA paradigms. Another advantage of CBM is that it is comprehensive and automatically identifies all holes and signals. The research findings are of interest and value to a variety of Federal and Commercial entities. The models and relevant model parameters for public safety radio in the LMR band have been provided on request to the Public Safety and Homeland Security Bureau of the Federal Communications Commission (FCC). The DSA feasibility analysis methodology is of great national economic interest based on the contents of the PCAST report. The PCAST report recommends finding 1000 MHz of federal frequencies to be allocated for shared commercial and federal use. However, the technology for doing so and identifying the suitable bands requires measurements of actual spectrum usage, modeling the occupancy and existing traffic activity, and assessing DSA feasibility – these are important research aspects, and all of which are addressed in this dissertation. The results are of crucial importance to policy makers like the FCC and NTIA who will ultimately make the spectrum allocations decisions. A future network of commercial DSA SU radios operating in a shared band is likely to need access to a system to obtain live information about PU activity to optimally operate in the band with high throughput and low interference. The overall system, based on the CBM procedure and HDO objects, proposed in this thesis describes a framework for providing this information as a service to DSA networks, and hence the work is also of practical relevance to radio system designers.

Show moreDespite the improvements in resources and communication in today’s world, many people still do not have access to mental health resources. Mindfulness, a type of meditation, has been shown to be effective at reducing stress, reducing pain, and increasing general mental well-being. Mindfulness has the potential to reach many people though internet-based interventions. However, more research is needed to determine whether mindfulness retains its efficacy when delivered over the internet. Participants engaged in a six week program of internet-based mindfulness interventions. Facets of mental well-being were assessed at various time points including mood state, anxiety, quality of life, mindfulness, and psychological inflexibility. Hierarchical Linear Modeling demonstrated that over time, participants significantly increased their level of mindfulness and decreased in their psychological inflexibility. Measurements pertaining to mood, anxiety, quality of life, and perceived stress did not change significantly. Nonetheless, results from the present study suggest the potential efficacy of internet-based mindfulness interventions and highlight the need for future research in this domain.

Show moreNanopore stochastic sensor using a biological protein ion channel has emerged as a powerful sensing technique due to its outstanding features such as label- and amplification-free detection, rapidness, high sensivity and selectivity. Development of a nanopore stochastic sensor for the rapid detection of anthrax can effectively prevent and control the spread of disease infection, and become extremely useful in biodefense. Two sensor design strategies were studied: one is chemistry-based detection of dipicolinic acid; and the other is genetics-based detection of anthrax lethal factor. Both approaches used in this study should find useful application in the development of nanopore sensors for the detection of other biomolecules and pathogens.

Show moreDeguelin, as a rotenoid, has emerged as an attractive pharmacophore for chemprevention due to its effectiveness for both in vitro and in vivo models. The biological activity and its structural complexity instigated the development of new synthetic technologies which could satisfy the increasing demand of deguelin, as well as broaden the diversity of the rotenoids. Here, a strategy of asymmetric acid-catalyzed annulations toward the enantioselective total synthesis of (-)-deguelin will be discussed. Several approaches were investigated to connect the chromene and phenolic moieties to create the pentacyclic rotenoid skeleton. Meanwhile, by collaborating with Professor Rajendra Mehta, several derivatives of deguelin were also made to study its bioactivity and interaction modes with specific proteins.

Show moreHuman noroviruses (HuNoV) are the leading cause of outbreaks of nonbacterial gastroenteritis in the U.S., and are often implicated in outbreaks associated with ready-to-eat foods, such as salads. Such foods may be extensively handled, and norovirus may be transferred readily between infected food handlers and food surfaces. The aim of this study was to investigate norovirus transfer between surfaces and romaine lettuce which were commonly used in the preparation of fresh food. Fresh Romaine lettuce was cut into 25cm2 pieces and inoculated with 25 μl (approx. 7-log PFU) murine norovirus (MNV-1) per leaf. After 10 min air-drying, 5 g piles of inoculated leaves were cut with a sterile stainless steel knife on a sterile cutting board. Sampling sponges soaked in Dulbecco’s Modified Eagle’s Media (DMEM) were used to swab blade and board surfaces for MNV-1 transferred from lettuce. In some cases, fresh, uninoculated Romaine lettuce was chopped using the contaminated knife and board. MNV-1 transferred to the chopped lettuce was recovered by stomaching in DMEM and enumerated by plaque assay. MNV-1 transfer was lower from contaminated lettuce to cutting board (p<0.05) than that from a contaminated cutting board to lettuce. This same trend was observed between a stainless steel knife and lettuce. The MNV-1 transfer coefficient was lower when contaminated lettuce was chopped on a wood board (p<0.05) compared to a polyvinyl cutting board. Norovirus transfers readily between surfaces common in the preparation of fresh produce preparation, but the transfer coefficient appears to be dependent on the surface type. This research provides the scientific basis for the development of a risk assessment model for norovirus transfer during the fresh food preparation.

Show moreAllergen cross-contact can be caused by inadequate cleaning of shared processing equipment. The objectives of this project were to evaluate the effectiveness of cleaning regimens on removing allergenic food residue from a pilot-scale cereal bar and muffin processing lines and measure the levels of allergens (peanut, milk and egg) transferred into allergen-free (control) cereal bars and muffins processed on an inadequately cleaned processing line. Another object was to investigate the analytical methods used (conventional ATP, sensitive ATP, total protein and lateral flow) to evaluate the effectiveness of allergen cleaning procedures. Cereal bars and muffins containing peanut flour, nonfat dry milk and egg powder (1000 or 5000 􀈝g/g for cereal bar and 100 or 5000 􀈝g/g for muffin) were manufactured on a pilot-scale processing line followed by one of four cleaning regimens: 1) push-through with control cereal bar dough or muffin batter, 2) scraping the equipment surfaces with rubber scrapers, 3) a rinse with hot (54-60°C) water until “visibly clean” and 4) a full cleaning cycle with alkaline detergent followed by use of a sanitizer. The adequacy of the cleaning treatments was assessed by swabbing locations (3 swabs/location) on the processing lines (cereal bar: mixer, depositor, conveyor belt; muffin: mixer, depositor, nozzle) followed by analysis of swabs with peanut-, milk-, and egg-specific lateral flow devices (LFDs). The cereal bar crosscontact study involved obtaining samples of the sheeted control dough transferred over the conveyor belt at 2 min intervals over a 30 min time span, or after approximately 100 kg of cereal bar dough was processed over the line previously contaminated with 5000 􀈝g/g allergen-incurred cereal bars. Similarly, allergen cross-contact from the contaminated muffin processing line into control muffins was measured by collecting xi 750g of control muffin batter until a total of 36 kg of batter were deposited. This was followed by allergen analysis of cereal bar and muffin samples (before and after baking) using quantitative ELISA kits. Results of LFD tests indicated that hot water rinse was effective for cereal bar processing line but not for the muffin line. Only the full cleaning cycle was effective at removing allergenic food residues for both processing lines. During the cross-contact study, substantial levels of peanut, milk and egg were detected in samples obtained both before and after baking. Cereal bar dough produced on the contaminated lines contained up to 71.9 ± 48.9 μg/g egg, 23.3 ± 1.3 μg/g milk, and 5.0 ± 0.4 μg/g peanut and as high as 2929.7 ± 98.8 μg/g egg, 1894.9 ± 87.7 μg/g milk, and 193.2 ± 20.6 μg/g peanut in muffin batter. Overall, these results illustrate the importance of validated cleaning protocols for preventing allergen cross-contact on shared processing lines.
