Whales, dolphins, and other marine mammals depend on their hearing to survive, but human technology is now invading their world. Military sonar used by the US Navy to detect submarines emit noises as loud as rocket blasts. These noises infiltrate the ocean and marine mammals get disoriented, have permanent hearing loss, get stranded, or die. With practical safety procedures in place, whales and other marine mammals can be protected from navy sonar. Striking a balance between the nation’s...
Show moreWhales, dolphins, and other marine mammals depend on their hearing to survive, but human technology is now invading their world. Military sonar used by the US Navy to detect submarines emit noises as loud as rocket blasts. These noises infiltrate the ocean and marine mammals get disoriented, have permanent hearing loss, get stranded, or die. With practical safety procedures in place, whales and other marine mammals can be protected from navy sonar. Striking a balance between the nation’s security and the safety of marine mammals can be achieved by passing legislation that takes into consideration both needs. With quality policies such as reducing sonar usage in times of peace in locations that have a high concentration of marine mammals and avoiding sonar use in areas in which they migrate to and feed from, marine mammals can be protected. These safety measures can be passed by using adjudicatory actions.

To that end, the minimum specimen size must be determined that will replicate this hazardous work environment. Samples of concrete stucco surfacing material (CSSM) of various sizes ranging from 1-in×1-in. to 8-in.×16-in. were applied to masonry blocks. These specimens were tested to determine the minimum size needed to produce 150-mg/m3 (one order of magnitude larger than the OSHA exposure limit of 15-mg/m3) of airborne particulate in a 1-m3 test chamber when removed with a chipping hammer. Testing results revealed that 5-in.× 5-in. specimen size yielded on average 180-mg/m3 of particulates.

Show moreAn important authentication method is multi-factor authentication (MFA). Products such as Enterprise Office 365 are already using it, available for any user in Office 365 Midsize Business, Enterprise, Academic, and Nonprofit plans as well as the standalone versions of Exchange Online and SharePoint Online. The log-in verification feature is aimed at reducing users' vulnerability to online identity theft, phishing, and other scams by adding a second level of authentication to an account log-in. Twitter, Apple, PayPal, Google, Facebook, and other vendors already have implemented it. After correctly entering their username and password, users need to acknowledge a phone call, text message, or an app notification on their smartphone before they can gain access to their account. Two-factor authentication is the most common form of MFA and requires the use of two of the three authentication factors: Something only the user knows, something the user has, and something only the user is. In this work we will analyze some varieties, do UML models of their structure and dynamics, and compare MFA to other authentication approaches.

This paper describes how such a misuse is performed from the view from an attacker, describes the systems involved in the misuse, analyzes methods of stopping or preventing the attack through potential security patterns, and details techniques that can be used to detect or trace such an attack after it has occurred. Such a pattern can inform IT managers, device manufacturers, or even device driver developers of the vulnerability, as well as detail methods or security patterns that can prevent an attack. A keyboard injection misuse attempts to infiltrate a system or network through a variety of techniques. Such a misuse impersonates a keyboard HID, which most systems inherently trust.

The remote input device is a gloved sensor fitted with flexing sensors that monitor an arthritic patient’s joint movement. The controller then sends the signal to be amplified to a normal full range of motion. That signal is sent to the robotic hand which plays the piano. Linear movement of the wrist is transferred with a sliding device. This project was a success and actually was able to assist people in remotely playing a scale on the piano.

Show moreThe Solid Waste Authority (SWA) of Palm Beach County collects leachate from its landfill in a gravity pipe leachate collection system (LCS), which is experiencing clogging due to calcium carbonate scale. An investigation was conducted to determine the solids composition and provide engineering solutions to this challenge. During testing, it was found that aerated leachate produced foam, which after vibration and evaporation, formed crystalline solids similar to those found in the SWA LCS. The following tests were conducted to determine the water quality of the leachate and the properties of the solids: pH, turbidity, chemical reactivity, biological growth, surface characteristics, and microscopic analysis. After five days of evaporation, the solids collected in all samples represented 46-47% of the leachate’s initial weight. On visual observation, the leachate remnants left both a crystalline and a dark slimy solid, with larger particles in the aerated samples, a possible source of the clogging.

The rotating rod is brought just above the oil/water boundary and is set to rotate at a speed greater than 200 revolutions per minute.

Show moreIn a tank filled with water at the bottom and oil floating on top, a straight rod reaching into the oil is set to rotate. The rotating rod is brought just above the oil/water boundary and is set to rotate at a speed greater than 200 revolutions per minute. It became evident that the rod’s rotation caused the oil/water interface to curve upward around the center of rotation, reaching up to the bottom of the rotating rod. Visible rings of water formed around the rod, starting at the bottom (at the oil/water interface) and ascending the rod, one by one. The water rings remained separate and ascended the rod until they eventually dispersed into the oil. Such quantization of water into rings has never been reported on before and represents a novel area of investigation in fluid dynamics. This study aims at obtaining quality photographic evidence to explain this phenomenon.

Show moreThe Durability of Reinforced Concrete (RC) structures in the Marine environment is causing increasingly serious concern in the structural infrastructures. RC structures, exposed to aggressive environments, are expected to last with little or no maintenance for long periods of time. However, one of the most serious environmental exposures that cause degradation is Chloride Diffusion, with tide-simulated wet and dry conditions at the air-water interface. This investigation, jointly project with Cemex (a cement mixing company), will address the change of chloride diffusion current resistivity due to macro and micro cracking, which is inevitable in all concrete structures. The correlation of Chloride Diffusivity with Electrical Current Resistivity of Sound and Cracked Concrete is studied experimentally, and the results compared with Analytically Determined values. The principal benefit of the research is the formulation of models to predict time-dependent Chloride Penetration into Sound and Cracked Concrete in the Marine environment.

The water cone is a polymeric cone that sits overtop a dish of saline water. The water is evaporated by the sun and condenses back onto the surface of the cone creating fresh water. In an attempt to improve the cone’s water production, two different hydrophobic coatings are applied to the inside of two cones, which allow water droplets to flow at a much faster rate, collecting water more quickly. Two water cones are coated separately, and are exposed to sunlight for five days. Water collection for the coated portion of the cone is compared to the uncoated portion of the cone. Results after a first trial show that coating A on the water cone impedes water collection whereas coating B appears to increase water collection.

A rotating platform supporting a beaker was controlled through a power supply. The power supply was adjusted and the dispersion patterns of the creamer were observed at 2, 4, and 6 volts. When added directly, at 2 and 6 volts, the coffee creamer displayed a pattern of swirling around the vertical axis with some dispersion radially towards the bottom of the beaker. At 4 volts bands were formed, which was likely the result of experimenter error. After the vegetable oil was added, the coffee creamer again displayed as swirls after crossing the oil but was not as distinct as when applied directly.

To this end, a reservoir supplying constant head and near-hydrostatic conditions was equipped with an exit fitting in its lower section. A section of PVC tubing extended vertically downward from this exit point and was straddled by a pair of dynamic loudspeakers placed opposite each other and connected to a receiver's inputs so as to play a signal of specified frequency. The resulting turbulent jet flow was then allowed to drop to a horizontal plate of circular shape. The outer lip of the plate triggered a circular hydraulic jump whose location was found to be directly dependent on the frequency of the forces exciting the flow.

Show morePorts and container terminals have very complex and dynamic operations. Effective and efficient berth schedules are essential for profitable and sustainable operations. This research studies berth scheduling under uncertainties in arrival and handling times. Port operators usually face challenges in the development of berth schedules. This thesis presents a model formulation of discrete berth space that accounts for uncertainty in arrival and handling times. The problem is reformulated as a biobjective bi-level optimization berth scheduling problem. A solution approach is presented using evolutionary algorithms and heuristics. The objective of the formulation is to provide a robust berth schedule by minimizing the average and the range of the total service times for all vessels served at the terminal. Simulation is utilized to evaluate the proposed berth scheduling policy and compare it to two first-come-first-served policies. Results showed that the proposed berth schedules outperform under high congestion.

This thesis presents a system for automatic parking lot occupancy computation using motion tracking. The use of computer vision techniques and low cost video sensors makes it possible to have an accurate system that allows drivers to find a parking spot. Video bitrate and quality reduction and its impact on performance were studied. It was concluded that high quality video is not necessary for the proposed algorithm to obtain accurate results. The results show that relatively inexpensive and low bandwidth networks can be used to develop large scale parking occupancy applications.

Show moreAnalog CMOS amplifiers are the building blocks for many analog circuit applications such as Operational Amplifiers, Comparators, Analog to Digital converters and others. This dissertation presents empirical design methodologies that are both intuitive and easy to follow on how to design these basic building blocks. The design method involves two main phases. In the first phase NMOS and PMOS transistor design kits, provided by a semiconductor foundry, are fully characterized using a set of simulation experiments. In the second phase the user is capable of modifying all the relevant circuit design parameters while directly observing the tradeoffs in the circuit performance specifications. The final design is a circuit that very closely meets a set of desired design specifications for the design parameters selected. That second phase of the proposed design methodology utilizes a graphical user interface in which the designer moves a series of sliders allowing assessment of various design tradeoffs. The theoretical basis for this design methodology involves the transconductance efficiency and inversion coefficient parameters. In this dissertation there are no restrictive assumptions about the MOS transistor models. The design methodology can be used with any submicron model supported by the foundry process and in this sense the methods included within are general and non-dependent on any specific MOSFET model (e.g. EKV or BSIM3). As part of the design tradeoffs assessment process variations are included during the design process rather than as part of some post-nominal-design analysis. One of the central design parameters of each transistor in the circuit is the MOSFET inversion coefficient. The calculation of the inversion coefficient necessitates the determination of an important process parameter known as the Technology Current. In this dissertation a new method to determine the technology current is developed. Y Parameters are used to characterize the CMOS process and this also helps in improving the technology current determination method. A study of the properties of the technology current proves that indeed a single long channel saturated MOS transistor can be used to determine a fixed technology current value that is used in subsequent submicron CMOS design. Process corners and the variability of the technology current are also studied and the universality of the transconductance efficiency versus inversion coefficient response is shown to be true even in the presence of process variability.

A direct thrust measurement system was designed for a waterjet propelled, free running USV. To induce sway velocity at the waterjet inlet, which was considered equivalent to the cross flow, circles of varying radii were performed at Reynolds Numbers between 3.48 x 106 and 8.7 x 106 and radii from 2.7 to 6.3 boat lengths. Sway velocities were less than twenty percent of mean forward speed with slip angles that were less than 20°. Thrust Loading Coefficients were compared to sway as a percent of forward speed. In small radius turns, no relationship was seen, while in larger radius turns, peaks of sway velocity corresponded with drops in thrust, but this was determined to be caused by reduced vehicle yaw in these intervals . Decoupling of thrust and yaw rate is recommended for future research.

Show moreFuture vehicles will exchange safety-critical information messages wirelessly with other vehicles on the road. We must provide secure mechanisms to validate the authenticity and integrity of these messages. The IEEE Standard 1609.2 defines the format of secure messages and identifies security algorithms and mechanism for use in Wireless Access in Vehicular Environment (WAVE). We propose an organizational structure for Central Management Entities (CMEs) to address these goals and functional requirements, and to balance the security of communications with protection of user privacy. A concern in vehicular communications is the privacy of vehicle owners. Privacy must be preserved and the user related information has to be protected from unauthorized access, while the authorities can trace the sender when there is a dispute. This thesis also presents a field operational test using IEEE 802.11a hardware. Vehicular test infrastructures can then be established in a cost effective manner to help support VANET research.

Show moreClimate models are common tools for developing design standards in the hydrologic field; however, these models contain uncertainties in multi-model and scenario selections. Along with these uncertainties, biases can be attached to the models. Such biases and uncertainties can present difficulties in predicting future extremes. These hydrologic extremes are believed to be non-stationary in character. Only in the recent past have model users come to terms that the current hydrologic designs are no longer relevant due to their assumption of stationarity. This study describes a systematic method of selecting a best fit model in relationship to location and time, along with the use of that best fit model for evaluation of future extremes. Rain gage stations throughout Florida are used to collect daily precipitation data used in extreme precipitation and quantitative indices. Through these indices conclusions are made on model selection and future extremes, as they relate to hydrologic designs.

This study assesses the viability of using a towfish mounted ADV for quantifying water velocity fluctuations in the Florida Current relevant to ocean current turbine performance. For this study a motion compensated ADV is operated in a test flume. Water velocity fluctuations are generated by a 1.3 cm pipe suspended in front of the ADV at relative current speeds of 0.9 m/s and 0.15 m/s, giving Reynolds numbers on the order of 1000. ADV pitching motion of +/- 2.5 [degree] at 0.3 Hz and a heave...

For this study a motion compensated ADV is operated in a test flume. Water velocity fluctuations are generated by a 1.3 cm pipe suspended in front of the ADV at relative current speeds of 0.9 m/s and 0.15 m/s, giving Reynolds numbers on the order of 1000. ADV pitching motion of +/- 2.5 [degree] at 0.3 Hz and a heave motion of 0.3 m amplitude at 0.2 Hz are utilized to evaluate the motion compensation approach. The results show correction for motion provides up to an order of magnitude reduction in turbulent kinetic energy at frequencies of motion while the IMU is found to generate 2% error at 1/30 Hz and 9% error at 1/60 Hz in turbulence intensity.
