Résumé :
This paper describes a measurement method for three-dimensional (3D) slit width deviations of long precision slot dies, which are essential for process control in manufacturing. A sensor unit consisting of two laser probes with their measurement axes aligned along the same Z-directional line but with opposite measurement directions, is placed between the two parts of the slot die to scan the two opposing surfaces of the parts along the X- and Y-axes. The variation of the sum of the laser probe outputs, which shows the deviation of the distance between the two surfaces, corresponds to the deviation of the slit width in the Z-direction. The 3D slit width deviations can be obtained accurately through scanning the entire surface in the X Y plane. In addition, the surface flatness of the parts can also be measured accurately by adding one more probe. Measurement experiments have been conducted on a precision grinding machine. The measurement results have indicated that the 3D slit width deviations and flatness can be measured with a repeatability error of less than 1 micron, which meets the requirement for quality control of slot dies.

Résumé :
Meander lines (MLs) in two configurations are presented to reduce the mutual coupling (MC) between two microstrip patch antenna elements. Inserting a slot in the ground plane between the antenna elements is a simple method to reduce the MC, while adding the MLs in the slot of the ground can further reduce the MC. In the first configuration, one ML is inserted in the slot of the ground and a maximum MC reduction of 39 dB throughout the −10 dB bandwidth is achieved. What’s more, the radiation patterns are not changed compared with the dual-element microstrip antenna array with a slotted ground. For the second configuration, two MLs are added in the slot of the ground. It is found that a maximum isolation of 53 dB can be obtained. However, the radiation patterns are slightly changed compared with the dual-element microstrip antenna array with a slot in the ground. Meanwhile, the measured peak gain and efficiency of the dual-element microstrip antenna array in the two configurations are given. Along with this paper, several prototypes have been fabricated and measured. The simulated results are in good accordance with the measurements, which are presented to verify that MC reduction can be achieved between microstrip antenna elements by adding the MLs in the slotted ground.

Résumé :
AbstractThis paper presents a cavity-backed dual-slot antenna in 0.13-μm SiGe BiCMOS technology. The dual-slot structure is excited by a cross-shaped strip line and a cavity which is formed by the topmost metal layer connected to the bottom metal layer through vias in between. By adopting dual-slot and cross-shaped feed line, the bandwidth is significantly enhanced by 196% compared with the single-slot antenna with straight feed line. The reason for bandwidth enhancement has been analyzed. The proposed antenna shows a measured impedance bandwidth of 15.2 GHz from 248.2 to 263.4 GHz for |S11| < −10 dB. The simulated and measured peak gains of the cavity-backed dual-slot antenna are −1.3 and −2.1 dBi, respectively. The simulated radiation efficiency is 31.1%. The total size of the antenna is 0.46 mm × 0.48 mm.

Résumé :
Post-reinforcement pause was examined to determine the reinforcing value of a win, loss, and a loss disguised as a win (LDW) for gamblers at multi-line video slot machines. The study was conducted in naturalistic settings across a variety of participants, age 21 years and older. The length of the post-reinforcement pause was recorded using a stopwatch for one win, one loss, and one LDW for each participant and was measured by recording the time between the outcome delivery and the initiation of the next spin. The different times were evaluated to determine which of the three resulted in the longest post-reinforcement pause for the gamblers following the slot machine outcome. The present study replicates and extends previous research on post-reinforcement pause in slot machine gambling, and provides discussion around the clinical utility of such findings on the prevention of problem gambling. Problem gambling is an epidemic, and there are numerous variables that contribute to its development. Post-reinforcement pause is one for those factors, and the present study can help us gain a better understanding of the events that maintain problem gambling and ways to prevent it. The results of the present study found that wins are the most reinforcing to gamblers compared to LDWs and losses, and that LDWs are significantly more reinforcing to gamblers than losses, as indicated by the patterns of the post-reinforcement pause.

Texte intégral
Résumé :
The aim of this study is to investigate the effects of changes in the physical parameters of tapered slot antennas (TSA) on their radiation characteristics and also to explore the possibility of reconfiguration in the radiation pattern of TSA by switching between two different types of tapering. There are mainly three physical parameters that affect the radiation pattern of TSAs. These are antenna length, aperture width and the ground extension. After designing a wideband microstrip line to slot line transition, the effect of antenna parameter variations on the beamwidth and sidelobe level of the antenna are investigated through the use of a commercially available electromagnetic simulation software HFSS by ANSOFT. The radiation characteristics of constant width slot antennas (CWSA) and linearly tapered slot antennas (LTSA) are compared. It is observed that CWSAs exhibit narrower beamwidth and higher sidelobe level whereas linearly tapered slot antennas (LTSA) have wider beamwidth with lower sidelobe level compared to each other. A novel switching architecture between CWSA and LTSA is proposed to obtain a reconfigurable antenna.

Résumé :
In this thesis the possibility of using radial line slot array (RLSA) antennas to provide low profile isoflux radiation patterns suitable for use as circularly-polarized tracking, telemetry & command (TT&C) antennas on low Earth orbit (LEO) satellites is investigated. The RLSA antenna elements are slot pairs located on concentric circles on the top plate of a radial waveguide. Conventional synthesis techniques cannot be used due to the fact that the RLSA antenna is a non-uniformly spaced array, the elements do not all have the same orientation, and the excitation amplitudes and phases are linked to the actual physical location of a particular slot pair. A technique is therefore developed for synthesizing such an RLSA antenna. Keywords: Antennas, Radial Line Slot Antennas, Isoflux Radiation Patterns

Texte intégral
Résumé :
A descriptive analysis was conducted to examine the influence minimum bets 30 credits and 50 credits had on the actual bets wagered on slot machines that operated on fixed-lines. Results suggested that slots with the lower minimum bets correlated with higher wagers. There was a total of 107 participants actively gambling at two casinos located just outside of Chicago, Illinois. The participant pool was divided between 37 males and 70 females. On average, the participants who played the slot machines with a minimum bet of 30 credits actually bet more than the participants who played the slot machines with a minimum bet of 50 credits. More notably, results from a Chi-square test for significance suggested that there is a significant influence between the minimum bet required to play and the presence, or absence, of “minimizers” and “maximizers” (p <.05). Additional data analyses where also conducted that examined gender’s role and wagering tendencies, including an independent t-test. The main purpose of this paper was to examine minimizing and maximizing gambling behavior across low-value and higher-value machines.

Résumé :
Technological advances in the aerospace industry have improved aircraft efficiency and reduced the cost of air transport, leading since 1960 to a continuous growth of the worldwide air traffic. Today it is postulated that also into the foreseeable future both the passenger and cargo air traffic will continue to growth, increasing the CO2 air transport emissions. In this contest, there are many environmental as well as commercial pressures on aircraft manufacturers to improve performances of future aircraft in terms of safety, air pollution, noise and climate change. To achieve these goals, it is necessary revisiting the whole aircraft architecture system, with the introduction of new technologies for performing key functions on aircraft. Today the conventional civil aircraft are characterized by four different secondary power distribution systems: mechanical, hydraulic, pneumatic and electrical. This implies a complex power distribution nets aboard, and the necessity of an appropriate redundancy of each of them. In order to reduce this complexity, with the aim to improve efficiency and reliability, the aerospace designer community trend is towards the `More Electric Aircraft (MEA)' concept, that is the wider adoption of electrical systems in preference to the others. This solution involves an increase of the aircraft electrical loads and, as a consequence, heavy implications for the on-board electrical generation systems are predictable. The resulting increase of the electrical power requirements encourage the research of alternative solutions rather than simply scaling up existing technologies such as generators driven by gearboxes. To address these challenges, many studies are in the direction of the so called `More Electric Engine (MEE)', in which the electrical machines are integrated inside the main gas turbine engine to generate electrical power, start the engine and guarantee safety generation in case of a critical on-flight failure. In this way the mechanical gearbox which connects the actual generators to the aeroengine shaft can be eliminated. The MEA and the MEE concept can be considered as an evolutionary implementation of the `All Electric Aircraft (AEA)', in which all the aircraft on-board systems are supplied in an electrical form. The MEE concept will involve important mechanical and thermodynamic implications in the aeroengine design, making necessary a preliminary system analysis on today conventional aeroengine, in order to evaluate the integration feasibility with the actual mechanical and environmental constraints. The electrical machines can be integrated inside the engine in some different positions, either in the front part before the combustion chamber, in particular in the low-pressure or in the high-pressure compressor stages, or in the rear part of the engine, in the tail-cone zone. In the frame of the GREAT2020 (GReen Engine for Air Transport in 2020) project co-founded by Regione Piemonte, aimed to the development of new eco-compatible aircraft engines for the entry into service in 2020, the MEE concept focus is on the evaluation of the most suitable solution between four possible integration positions in the front part of the today conventional two-shaft GEnx turbofan engine. The rotational speeds and the maximum available volumes are respectively imposed by the shaft connection and by the available spaces inside the aeroengine. In the purpose of the MEE concept on which the work presented in this dissertations is based, in order to evaluate the less critical solution between the proposed, a trade-off study conducted on preliminary electromagnetic design has been performed considering both radial and axial flux surface mounted permanent magnet synchronous machines. The comparison of the different solutions have been done on the base of same sizing indexes. Due to the particular application in which the electrical machine integration is involved, in order to evaluate impact on the whole system performance, a wider trade-off study concerning the overall aeroengine system has been done by the aerospace company Avio, partner of the GREAT2020 project. The focus of the work presented in this dissertation, is the development of appropriate tools to perform a preliminary electromagnetic design of radial and axial flux, surface mounted, permanent magnet synchronous machines with three-phase distributed and single-layer fractional-slot non-overlapping concentrated windings. In particular, this latter winding topology has been considered for its specific application for its shorter end-winding connections respect to the distributed layout, and for their high fault tolerant capability due to the electrical and physical separation between the phases which reduces the possibility of a fault propagation. Regarding the radial flux topologies, both inner and outer rotor machine structures have been considered; for the axial flux machines the single-stage (one stator and one rotor) as well as the multi-stage structures, obtained connecting on the same axis more than one single-stage structure, have been considered. The developed general purpose tools are based on simple geometrical approach using conventional design equations. The geometrical dimensions are computed starting from the design specifications and material utilization indexes imposed by the designer. The implemented codes would be a useful tool for the electrical machine designer in order to quickly define a preliminary electromagnetic design starting from a fresh sheet of paper. The conducted comparisons with commercial software have proved the validity of the tools for the conducted MEE trade-off study; however, in a prototype design aimed to the construction, detailed analysis using commercial software available on the market and Finite Element Method analysis have to be done in order to verify and improve in details the preliminary electromagnetic design obtained by the implemented codes.

Résumé :
Thesis focuses on the design and development of three possible methods to power the serial patch array and optimization of the chosen design. The antenna array is conceived as a multi-layered structure formed on a 3D textile substrate. The objective of this work is to identify the best possible configuration of antenna array for the use in automotive and aerospace industry. The first concept – array coupled by near microstrip line – proved in the case of the more serial elements as non-functional. The second concept – aperture coupled array – is unsuitable for use in close proximity to the electrically conductive shell of the aircraft. The third concept – array coupled with textile integrated waveguide – seems like the best possible solution. The design of the array coupled with textile integrated waveguide was optimized in consideration of the production process. The impedance bandwidth of this proposed three elements antenna is 890 MHz, the gain in the main lobe direction is 11.8 dBi.

AbstractTo raise the income of the container liner company and improve the shipping space utilization rate, an integer programming model is constructed in view of the seaworthiness characteristics of each ship route along Hanshen line of the Yangtze river, OD container transport demand, and the container rental business under the alliance. Aiming to maximize the gross profit of the Hanhai liner shipping fleet series, the container was optimized route network along the Yangtze river waterway and determined how to choose the port call for each route and the types of vessels. While optimizing, the model is established according to the characteristics of liner multi-port attachment and cargo nonstop transportation routes, comprehensively considering various factors including freight demand, maximum cargo capacity of a single ship, minimum voyage frequency, and freight rate level. The numerical analysis of the Hanhai fleet turns out that the model can perfectly simulate the situation in reality and optimize the existing routes and boost the profits of liner transportation companies.

Résumé :
AbstractDrop impact on a hot surface heated above the saturation temperature of the fluid plays an important role in spray cooling. The heat transferred from the wall to the fluid is closely interrelated with drop hydrodynamics. If the surface temperature is below the Leidenfrost temperature, the heat transport strongly depends on the transport phenomena in the vicinity of the three-phase contact line. Due to extremely high local heat flux, a significant fraction of the total heat flow is transported through this region. The local transport processes near the three-phase contact line, and, therefore, the total heat transport, are determined by the wall superheat, contact line velocity, system pressure, fluid composition, surface structure and physical properties on the wall. The effect of the aforementioned influencing parameters on fluid dynamics and heat transport during evaporation of a single meniscus in a capillary slot are studied in a generic experimental setup. The hydrodynamics and evolution of wall heat flux distribution during the impact of a single drop onto a hot wall are also studied experimentally by varying the impact parameters, wall superheat, system pressure, and wall topography. In addition, the fluid dynamics and heat transport behavior during vertical and horizontal coalescence of multiple drops on a heated surface are studied experimentally.

Texte intégral
Résumé :
Stress corrosion cracking of line pipe from the soil side involves slow crack growth at stresses which may be as low as half the yield strength, this slow crack growth continuing until the crack penetrates the wall to produce a leak or until the stress intensity on the uncracked ligament reaches the value for a fast fracture to penetrate the wall thickness. The controlling parameters that contribute to the mechanism of failure, essentially involving growth by dissolution in the grain boundary regions, are, as with other systems displaying such failure, electrochemical, mechanical, and metallurgical, acting conjointly. Electrochemical influences relate to environment composition, potential, and its variation under disbonded coatings and temperature, whilst mechanical factors of significance include pressure variations, and their time dependence, as well as maximum pressure. Metallurgical parameters, whilst not yet fully understood, including those aspects of steel composition and structure that influence grain boundary composition and the microplasticity associated with load changes, as well as surface condition, e.g. the presence or otherwise of mill scale. These controlling parameters indicate the remedial measures available for control of the problem, although some, for practical or economic reasons, are not invariably applicable. Thus, control by metallurgical approaches or through coatings or manipulation of the surface conditions is only applicable to future lines, but for those already in existence lowering the temperature, limiting pressure fluctuations and more precise control of cathodic protection should help alleviate the problem.

Résumé :
This report summarizes the effort to evaluate the sour fracture toughness properties of two thermo-mechanically controlled processed (TMCP) pipes and a plate material in sour environments with different H2S partial pressures. The primary objective of the project was to measure the fracture toughness properties of two TMCP pipes and a plate material in sour environments at three levels of H2S partial pressures ranging from 0.1 psia to 200 psia. The project also evaluated the Sulfide Stress Cracking (SSC) and Hydrogen Induced Cracking (HIC) susceptibilities (for selected conditions) of materials. Constant load and constant displacement tests were performed for two of the three H2S levels to determine the initiation toughness as compared to that determined in the slow rising displacement fracture toughness (FT) tests.
