Measuring and filtering microwave radiations using frequency selective surface through energy saving glass

This thesis presents the results of our investigation into the measurement and filtering of microwave radiation, and the subsequent development of a microwave reduction solution for modern building architecture utilising Energy Saving Glass (ESG), in conjunction with Frequency Selective (FSS) surfaces through which useful signals can be filtered. In the investigation, radiation power density levels arising from the three common microwave sources (radio base stations, mobile phones, and microwave ovens) were measured, and the results were compared with the standards provided by the Australian Radiation Protection and Nuclear Safety Agency. For the radio base stations, the relationship between radiation intensity levels and the important location parameters at the measurement point, e.g., line of sight, distance and elevation, are discussed in detail. Our results show that locations having the same elevation level as the RBS receive higher level of radiation, compared to those locations not at the same level. Power density of the radiation from microwave ovens was measured at various distances and angles. The results indicate that most of the radiation is emitted through the main door of the ovens, with the doors normally being assembled utilising simple float glass. ESG was found to have desirable radiation attenuating characteristics, and was identified as an effective replacement for float glass in microwave oven doors. In our investigation of the third potentially hazardous source of microwave radiation, the mobile handset, measurements were carried out in order to analyse power density levels during both call and idle times. Our results confirm that some handsets do not change power level, while others use higher power to communicate with the base station during a call. It is our recommendation that the manufacturers label each handset with the specific transmission power level in order to provide users with the relevant information. The conclusions drawn from our investigations lead us to recommend that ESG be used in buildings close to RBS, so that the levels of unnecessary radiation are reduced. However, useful signals would still be transmitted by utilising the dual bandpass FSS filters designed as part of this work. We designed two distinct models of bandpass FSS filters on hard coated ESG. The first filter that we designed will block microwave signals coming from weather radar, personal communication devices, power transmission lines and emergency service radios, while transmitting useful UMTS and Wi-Fi signals; minimising the radiation impact. Only 7.30% of the coating area of the glass was removed to enable transmission in the U850 and U2100 frequency bands. The second design requires the removal of 12.35% of the coating area to enable transmission in the U800, U850, U1900 and U2100 frequency bands. Simulation results for the two designs show stable frequency responses for both TE and TM polarisations at normal and oblique incident angles, with attenuation's below 10 dB within the passbands.

Modeling to Support Groundwater Contaminant Boundaries for the Shoal Underground Nuclear Test

The purpose of this work is to characterize groundwater flow and contaminant transport at the Shoal underground nuclear test through numerical modeling using site-specific hydrologic data. The ultimate objective is the development of a contaminant boundary, a model-predicted perimeter defining the extent of radionuclide-contaminated groundwater from the underground test throughout 1,000 years at a prescribed level of confidence. This boundary will be developed using the numerical models described here, after they are approved for that purpose by DOE and NDEP.
Humanoid Robot Motion in Unstructured Environment - Generation of Various Gait Patterns from a Single Nominal

Humanoid robotics has been in the focus of scientific community for decades. For a long time already, robots have not been present only in the industrial plants, at a time their traditional work space, but have been increasingly more engaged in the close living and working environment of humans. This fact inevitably leads to the need of “working coexistence” of man and robot and sharing their common working environment. The fact that no significant rearrangement of the environment of humans could be expected as a consequence of the presence of their mechatronic partners, robots will have to further “adapt” to the environment previously dedicated only to men. Besides, it is expected that the robots cooperating with humans will have an operation efficiency matching that of humans. The working and living environment, adapted to humans, imposes on robot's mechanical-control structure at least two types of tasks related to its motion: motion in a specific environment with the obstacles of th e type of staircases, thresholds, multi-level floors, etc., and the motion within a very dynamic scene in which the trajectory of system’s motion can be only globally planned and the actual trajectory determined on the basis of the instantaneous situation.

Cold atoms and molecules by Zeeman deceleration and Rydberg-Stark deceleration

The preparation of atomic and molecular samples in selected internal quantum states at translational temperatures below 1 K by multistage Zeeman deceleration and Rydberg-Stark deceleration is described. The technique of multistage Zeeman deceleration exploits the interaction of paramagnetic atoms or molecules with inhomogeneous magnetic fields. It is suited to the deceleration of ground-state paramagnetic samples or those in long-lived, low-lying metastable states, which are initially moving in pulsed supersonic beams. Rydberg-Stark deceleration involves the photoexcitation of atoms or molecules to selected Rydberg states of high principal quantum number, n, which exhibit electric dipole moments on the order of 1000 Deybe. The interaction of samples in these states with inhomogeneous electric fields is exploited for acceleration, deceleration and trapping. The development of the technique of multistage Zeeman deceleration, which is described in this thesis, has centred around the deceleration of beams of hydrogen and deuterium atoms. Experimental studies of the particle dynamics within the decelerator have been performed and compared to the results of numerical simulations of particle trajectories, to quantify and optimise the efficiency of the deceleration process, and to minimise undesirable particle loss, for example via state-changing during the rapid switching of the ∼ 2 T magnetic fields of the decelerator. This has led to the first demonstration of magnetic trapping after multistage Zeeman deceleration which was achieved using hydrogen atoms, and the first demonstration of magnetic trapping deuterium atoms by any method. The trapped samples were detected by photoexcitation to Rydberg states followed by pulsed electric-field ionisation or by direct photoionisation, and exhibited translational temperatures of Ekin/kB ∼ 100 mK and number densities of ∼ 106 cm−3. Using a single-stage Rydberg-Stark decelerator and a three-dimensional electrostatic trap with a non-zero electric-field minimum, measurements,

Assessing Urban Crime and its Control: An Overview

Urban crime rates in the United States fell markedly during the 1990s and remain at historically low levels. The statistical evidence presented here indicates that that decline, like the crime surge that preceded it, has been largely uncorrelated with changes in socioeconomic conditions across cities. The ups and downs of crime have a considerable effect on residential location and property values. The police represent the largest public expenditure in city-level crime control efforts, and they are increasingly held accountable for reducing crime rates. Indeed, there is considerable evidence that an increase in police expenditures does pay off in the form of lower crime rates. This is an incomplete story, however. Assessments of police effectiveness typically neglect the considerable role of private and community-level protection and control efforts, not to mention the vital importance of (uncompensated) private inputs into police investigations. In areas with endemically high violence rates, the reluctance of witnesses to cooperate remains a serious problem.
OLDER DRIVERS WITH VISION PROBLEMS

Driving records (1987 to 1990) for 7,500 class 5 (automobile) permit holders aged between 70 and 85 years were collected from different files (permit holders, medical, infractions, demerit points, crashes) of the public insurer for injuries (SAAQ) to answer the following question: Do older drivers (70 to 85) with certain vision problems have a worse driving record than healthy ones of the same age? After cross validation of the health status with additional information from the Quebec provincial health insurance (RAMQ), up to six groups with specific vision problems, mainly low acuity (e.g., 20/40 or 20/50 for the best eye) and visual field reduction, were retained for comparisons with a corresponding healthy group with good vision, separately for women and for men. Straightforward comparisons of the mean number of crashes per year and count data regression models (Poisson regression and generalizations) were used. Explanatory variables included health status, age and risk exposure obtained through a telephone survey. The results show that in general the mean rates of crashes per year per permit holder for groups with vision problems are very similar to the means of the corresponding groups of healthy permit holders. However, the count data regression models indicates that a few cohorts of older drivers with vision problems register a higher crash risk than their controls: women (permit holders) aged 76 to 80 with vision 20/40 and 0 registered a crash risk of 2.59, those with other eye problems 3.65, and even, 4.05 for the non respondents. The risks for men aged 68 to 75 when taking into account risk exposure are 1.62 (20/50 and 20/100, or 20/200) and 1.36 (20/40 and 0). Older drivers tend to adjust their driving behavior in accordance with their limitations. Our results which have shown higher risk ratios for some cohorts do not support relaxing further the regulations for the elderly driver. Language: en
Truck and rail shock and vibration environments during normal transport

The Sandia National Laboratories Transportation Technology Center (SNL/TTC) provides technical management and support for programs which span a broad range of technical problems related to the transport of nuclear materials. As part of this program, SNL has obtained data on the shock and vibration experienced by large shipping casks during normal transport. The data were obtained by: (1) extracting, reviewing, and reducing the shock and vibration environment definitions on file in the DOE/DOD and DOE Transportation Data Banks;( 2) determining the best estimates of the environments for large shipping containers on trucks and railroad cars; (3) defining and conducting tests to obtain any additional data required; and (4) conducting dynamic analyses of the shock environment experienced by cargo during rail switching and coupling to identify the dependence of the shock environment on heavy cargo weights and on shock attenuation couplers.

Car Infotainment: An early analysis of driver perceptions towards apps in the car

Driven by technological advances, the vision of a Connected Car finally becomes reality. As one of the Connected Car innovations, Car Infotainment Systems now get an internet connection. Following the example of the mobile industry, app ecosystems are about to emerge in cars. In-Vehicle technology has already become the new differentiation battleground in the automotive industry. Being technologically possible, however, does not guarantee the success of app-based Car Infotainment Systems. It is not clear whether these systems are appreciated by car drivers, seeing that apps not necessarily provide assistance for driving, but in contrast can be a source of driver distraction and thus threaten traffic safety. It was therefore the purpose of this study to explain the perceptions of car drivers towards Car Infotainment Systems that provide access to an App ecosystem and thereby determine success factors from a user’s perspective. For this reason, a research model that extends the Technology Acceptance Model with hypothetical factors has been proposed based on a literature review on driver acceptance. By analyzing data collected through an online survey, perceptions have been measured and nine hypotheses among these factors have been tested. It could be shown that drivers’ perceptions of Car Infotainment Systems are slightly positive. Task-technology-fit, usefulness, ease of use, risk and costs could be approved as being influencing factors of the behavioral intention to use Car Infotainment Systems. However, the perceived risk seems to have no direct influence. Implications for both practice and academia could be drawn from these results.
CFD prediction of ship capsize: Parametric rolling, broaching, surf -riding, and periodic motions

Stability against capsizing is one of the most fundamental requirements to design a ship. In this research, for the first time, CFD is performed to predict main modes of capsizing. CFD first is conducted to predict parametric rolling for a naval ship. Then CFD study of parametric rolling is extended for prediction of broaching both by using CFD as input to NDA model of broaching in replacement of EFD inputs or by using CFD for complete simulation of broaching. The CFD resistance, static heel and drift in calm water and static heel in following wave simulations are conducted to estimate inputs for NDA and 6DOF simulation in following waves are conducted for complete modeling of broaching. CFD parametric rolling simulations show remarkably close agreement with EFD. The CFD stabilized roll angle is very close to those of EFD but CFD predicts larger instability zones. The CFD and EFD results are analyzed with consideration ship theory and compared with NDA. NDA predictions are in qualitative agreement with CFD and EFD. CFD and EFD full Fr curve resistance, static heel and drift in calm water, and static heel in following waves results show fairly close agreement. CFD shows reasonable agreement for static heel and drift linear maneuvering derivatives, whereas large errors are indicated for nonlinear derivatives. The CFD and EFD results are analyzed with consideration ship theory and compared with NDA models. The surge force in following wave is also estimated from Potential Theory and compared with CFD and EFD. It is shown that CFD reproduces the decrease of the surge force near the Fr of 0.2 whereas Potential Theory fails. The CFD broaching simulations are performed for series of heading and Fr and results are compared with the predictions of NDA based on CFD, EFD, and Potential Theory inputs. CFD free model simulations show promising results predicting the instability boundary accurately. CFD calculation of wave and rudders yaw moment explains the
Incorporation of Fluconazole and Ocimum Sanctum Oil in Soft Denture Liners to Treat Biofilms of Candida albicans Associated with Denture Stomatitis

Purpose: To investigate the In Vitro activity of incorporated antifungal agents like Fluconazole and Ocimum sanctum oil (Tulsi) in the denture soft liners to reduce the risks associated with the biofilms of Candida albicans.Materials and Methods: In the current study, the minimum inhibitory concentration (MIC) of two antifungal agents namely Fluconazole and O. sanctum (Tulsi oil) against C. albicans (ATCC 10231) was evaluated to examine their effect in reducing the count of candida and its biofilms. Analysis of physical properties such as surface roughness and hardness of soft denture liners (test and control) were also performed. The effect of both antifungal agents was also observed on cell morphology of candida cells using scanning electron microscopy (SEM). Results: Studies confirmed MIC value for fluconazole and O. sanctum oil as 600 and 400 µg/ml respectively. Surface hardness and roughness of soft denture material (test) remained unaltered. Finally, SEM studies also proved the effectiveness of incorporated antifungal agents on the cell morphology of C. albicans at their respective MIC values.Conclusions: This approach allows the prolonged drug release in the oral cavity which simultaneously treats the injured denture bearing tissues and also the infection, biofilms of candida without compromising on their physical properties. These studies are significant and have tremendous medicinal and therapeutic relevance.
High-order computations on aerofoil-gust interaction noiseand the effects of wavy leading edges

High-order accurate numerical simulations are performed to investigate the effects of wavy leading edges on aerofoil gust interaction (AGI) noise. The present study is based on periodic velocity dis-turbances predominantly in streamwise (x-) and vertical (y-) directions that are mainly responsible for the surface pressure fluctuation of an aerofoil. The perturbed velocity components of the present gust model do not vary in the spanwise (z-) direction. In general, the present results show that wavy leading edges lead to reduced AGI noise. Under the current incident gusts, it is found that the ratio of the wavy leading-edge peak-to-peak amplitude (LEA) to the longitudinal wavelength of the incident gust (? g) is the most important factor for the reduction of AGI noise. It is observed that AGI noise reduces with increasing LEA/? g, and significant noise reduction can be achieved for LEA/? g? 0.3. The present results also suggest that any two different cases with the same LEA/? g lead to a strong similarity in their profiles of noise reduction relative to the straight leading-edge case. The wavelength of wavy leading edges (LEW), however, shows minor influence on the reduction of AGI noise under the present gust profiles used. Nevertheless, the present results show that a meaningful improvement in noise reduction may be achieved when 1.06LEW/? g 61.5. In addition, it is found that the beneficial effects of wavy leading edges are maintained for various angles of attack and aerofoil thicknesses. Also, wavy leading edges remain effective in reducing AGI noise for gust profiles containing multiple frequency components. It is discovered in the current research that wavy leading edges result in in-coherent response time to the incident gust across the span, which causes a decreased level of surface pressure fluctuations, hence a reduced level of AGI noise.
