Radio Frequency Toolbox For Drone Detection and Classification

Radio Frequency Toolbox For Drone Detection and Classificati...

引用

作者： Abdulkabir, Bello Old Dominion University

学位级别：M.S.

The continuous development of inexpensive embedded sensors has led to the rapid proliferation of new civilian use of unmanned aerial vehicle (UAVs) or drones. It is now easier for civilians to own drones as the cost falls. As we all know drones have a variety of important applications and can also be used for negative effects too. These drones can pose a threat to the security of the population either civilian, organization or industry. There is a need for Radio Frequency Signal Classification (RF-Class) toolbox which can monitor, detect, and classify RF signals from drone communication system. The ability to accurately classify over-the-air radio signals will provide insights into spectrum utilization, device fingerprinting and protocol identification. These insights can help the Warfighter to constantly be informed about adversaries transmitters capabilities without their knowledge. The advantage of the drone detection and classification toolbox is extracting information about transmitters and providing receivers information about transmitted signals. The classification of RF signals will be done based on the modulation scheme, in this case, orthogonal frequency division multiplexing (OFDM). The signal energy and features from the signals leveraging its orthogonal frequency division multiplexing(OFDM) parameter information will be used to classify the signal. This classification will be done using the capabilities of machine learning to train and test the information collected. The content of this thesis discusses how drone detection and classification can be achieved using software defined radio. GNU radio and other hardware components will be used to implement a simulation of the module.

Development of Semantic Scene Conversion Model for Image-based Localization at Night

Development of Semantic Scene Conversion Model for Image-bas...

引用

作者： Kim, Dongyoun South Dakota State University

学位级别：M.S.

Developing an autonomous vehicle navigation system invariant to illumination change is one of the biggest challenges in vision-based localization field due to the fact that the appearance of an image becomes inconsistent under different light conditions even with the same location. In particular, the night scene images have greatest change in appearance compared to the according day scenes. Moreover, the night images do not have enough information in Image-based localization. To deal with illumination change, image conversion methods have been researched. However, these methods could lose the detail of objects and add fake objects into the output images. In this thesis, we proposed the semantic objects conversion model using the change of local semantic objects by categories at night. This enables the proposed model to obtain the detail of local semantic objects in image conversion. As a result, it is expected that the proposed model has a better result in image-based localization. Our model uses local semantic objects (i.e., traffic signs and street lamps) as categories. The model is composed of two phases as (1) instance segmentation and (2) semantic objects conversion. Instance segmentation is utilized as a detector for local semantic objects. In translation phase, the detected local semantic objects are translated from the appearance of the night image to day image. In evaluation, we prove that models using a set of paired images show higher accuracy compared to the models using a set of unpaired images. Our proposed method will be compared with pix2pix and ToDayGAN. Moreover, the result quantitatively evaluates the best matching score with a query image and the converted images using ORB matching descriptor.

Min-Max Inverse Reinforcement Learning for Learning Bi-Modal Dialogue Policies

Min-Max Inverse Reinforcement Learning for Learning Bi-Modal...

引用

作者： Patil, Gandharv McGill University (Canada)

学位级别：M.E.

In this thesis, we explore the use of Inverse Reinforcement Learning (IRL) in image-based dialogue systems. Visually-grounded dialogue systems are still in their infancy. Their success hinges on an efficient feature extraction method and the training mechanism used for learning the language model. At present, dialogue systems trained using maximum likelihood estimation tend to produce deflective or uninformative responses. We propose to tackle this issue by formulating the dialogue generation problem in the IRL setup. To that end, we adapt the IRL framework for processing complex high- dimensional inputs by leveraging a connection between deep learning, min-max optimisation and energy-based models. We also propose a neural network architecture for generating state representation by combining signals from text and image modalities. Finally, we show that subject to the availability “enough” training data; our proposed method can mitigate the issue of bland or deflective responses

Large-Scale DER Aggregations of Electric Water Heaters and Battery Inverter Systems

Large-Scale DER Aggregations of Electric Water Heaters and B...

引用

作者： Marnell, Kevin Portland State University

学位级别：M.S.

Distributed energy resources like residential electric water heaters and residential battery inverter systems offer a small amount of change to the grid individually. When aggregated however, these assets can cause major effects to the electric grid. Aggregating these resources allows them to take on generator-like functions with the ability to increment power and decrement power. The Western Energy Imbalance Market is an energy market offering 15 minute and 5 minute markets for energy transactions between balancing areas. Generation assets make increment and decrement bids. Traditionally the only entrants to this market have been large scale generators and large scale assets legally designated as generators. Aggregated distributed resources could offer the same increments and decrements from managing residential assets like electric water heaters and batteries. DERAS, a Distributed Energy Resource Aggregation System developed by the Portland State Power Lab group, is an aggregator of residential resources that could offer increment and decrement bids to an energy market, like an Energy Imbalance Market. This research models and simulates aggregations of distributed energy resources. This work analyzes the effects of 10,000 electric water heaters and 10,000 battery inverter systems. A simulation program was built to simulate regular use of these assets, and then add the additional effects of a decrement bid into the Western Energy Imbalance Market. The effects of the bids on energy levels inside the water heaters and batteries are examined. The power imported from the grid is also analyzed as an effect of the aggregator attempting to cover a generation decrement bid.

Loudness Estimation Through Evoked Responses at Audiometric Frequencies

Loudness Estimation Through Evoked Responses at Audiometric ...

引用

作者： Sasson, Yonatan Northeastern University

学位级别：M.S.

Procedures for evaluating individual loudness functions through tone burst evoked auditory responses—both Tone-Burst Otoacoustic Emissions (TBOAE) and Tone-Burst Auditory Brainstem Responses (TBABR)—have been investigated in the past and have yielded credible results for a limited stimulus frequency range across a wide range of levels. The aim of this work is to investigate this relationship further by expanding the frequency range examined to cover a more full audiometric range and expand the analysis parameters for an objective and thorough analysis process. Evoked-responses (TBOAE and TBABR) were recorded from six normal hearing listeners for 17 different levels and seven frequencies (250, 500, 1000, 2000, 4000, 6000 and 8000 Hz). The recordings were analyzed and the results compared to two psychoacoustic procedures: Cross Modality Matching (CMM) and Magnitude Estimation (ME). Results for TBOAEs show agreement with results from previous studies for 1-kHz and 4-kHz and support the assumption that recorded signals at 500 and 2000 Hz are strong enough for such analysis, while analysis of signals at 250 and 8000 Hz are feasible but suffer from weak OAE response compromising the robustness. Recordings at 4000 and 6000 Hz were too contaminated to produce consistent results due to ear canal resonance. Results for TBABRs also show agreement with results from previous studies for 1-kHz and 4-kHz, and also exhibit consistency throughout the selected frequency range.

Autonomous tracking of mussels in a lab environment

Autonomous tracking of mussels in a lab environment

作者： Diken, Mehmed Bilal The University of Iowa

学位级别：M.S.

Rapid global industrialization and increase in human population over the last century has exponentially increased the demand of fossil fuels for energy, (generation of electricity, fuel for transportation, etc), and an ever expanding list of fossil fuel derived chemicals, (synthetic fertilizers, pesticides, polymers, etc), are being used in all aspects of daily life. All of this has inevitably introduced large amounts of nitrogen to earth's Nitrogen Cycle. Thus, one of the challenges put forth by the National Academy of engineering (NAE) has been the management of the Nitrogen Cycle. (NAE, 2008). It's anticipated that the effects of human-induced changes to the global Nitrogen Cycle will be profound, and needs to be better studied and understood. Previous investigations on mussels were conducted in artificial conditions, mostly in a small scale where the mussels were restricted and tethered. These studies were conducted to mature and test technologies for the possibility of developing systems to monitor mussel un-tethered/wirelessly. The wireless communication between mussels introduces electronics that needs to be mounted external to the shell of these animals. The big picture goal of the entire study is to enable scientist to monitor mussels un-tethered in their natural environment. To achieve this goal we must first verify the following assumption: "The attachment of sensors and a small "backpack" containing wireless communicators and sensing electronics will have little or no impact on mussel mobility and survival." In this paper we explore multiple methods and devise a well functioning system that can autonomously identify, track and log the movement of mussels in a mesohabitat to be able to verify our assumption above.

Channel adaptive real-time medium access control protocols for industrial wireless networks

作者： Balasubramanian, Kavitha Iowa State University

学位级别：M.S.

Wireless technology is increasingly finding its way into industrial communication because of the tremendous advantages it is capable of offering. However, the high bit error rate characteristics of wireless channel due to conditions, such as attenuation, noise, channel fading and interference seriously impact the timeliness and reliability guarantee that need to be provided for real-time traffic. Existing wireless protocols either do not adapt well to erroneous channel conditions or do not provide real-time guarantees. The goal of our work is to design and evaluate novel real-time MAC (Medium Access Control) protocols for combined scheduling of periodic and aperiodic messages taking into account the time-varying channel condition. Our first contribution is the design of a combined scheduling algorithm that exploits both spatial and temporal diversity of the wireless channel through "exchange of slots" among nodes, to effectively mitigate bursty channel error conditions. Simulation results show that the proposed algorithm achieves significant improvements in message success ratio compared to baseline protocols under a wide range of traffic and channel conditions. The second contribution assumes a two-level hierarchical network in which nodes are grouped into clusters and the communication occurs within each cluster and across clusters. The goal is to maximize the schedulability of intra- and inter-cluster periodic and aperiodic messages with deadline guarantees. In this context, we propose an Adaptive protocol that maximizes the channel utilization by enabling parallel transmissions in a collision-free manner, in conjunction with the use of the slot-exchange technique to actively combat the erroneous channel conditions. Through simulation studies, we show that the proposed Adaptive protocol achieves significant improvement in packet loss performance compared to the baseline protocols that exploit complete parallelism and full exchange, for a wide range of channel con

作者： Mohammad, Imaduddin Purdue University

学位级别：M.S.E.C.E.

With the recent advancements in semiconductor manufacturing towards smaller, faster and more efficient microelectronic systems, the problems of increasing leakage current and reduced breakdown voltage in bulk-CMOS transistors have become substantial in the sub-100-nanometer era. The Peregrine UltraCMOS Silicon-on-Sapphire (SOS) technology that uses highly-insulating sapphire substrate as insulator was introduced to meet the continually growing need for higher performance RF products. The electrically isolated circuit elements in the UltraCMOS technology lead to increased switching speeds and lower power consumption due to reduced junction and parasitic capacitances. Furthermore, the growing need for high-speed switching applications such as boosting a lower voltage level to a higher one gives the UltraCMOS technology an upper hand over the bulk-CMOS process. The limitation to using an UltraCMOS transistor is that its maximum drain to source voltage (VDS) swing is 2.5V. This thesis aims to address this limitation by studying and implementing various stacking techniques in high power switching applications where voltage switching of higher than 2.5V are required. Fully-integrated DC to DC boost converters with switching circuits based on dynamically self-biased stacked transistors are proposed. For high voltage and high power handling, the proposed stacking techniques equally distribute the overall output voltage to less than 2.5V across each stacked transistor in the switch (VDS of 2.5V).

As sport-related traumatic brain injuries face increasing attention from the media and the general public, the need to be able to detect brain injury quickly, inexpensively and accurately is more important than ever. Commercially-available event-based systems exist that claim to achieve this goal; however, they collect little to no continuous-time data and primarily indicate when a pre-determined acceleration threshold has been exceeded under the unvalidated assumption that a potentially concussive blow has occurred. Recent findings by the Purdue Neurotrauma Group (PNG) have indicated that repeated exposure to both concussive and subconcussive blows can result in cumulative trauma disorder. To track cumulative trauma over time it is necessary to record all accelerations experienced by the head. The lack of effective commercially-available systems resulted in the PNG undertaking the development of a custom hardware platform that allows real-time telemetry. This project focuses on the analysis of various designs for an effective hardware platform intended specifically for use in contact-sport settings. The analysis investigates both commercially available systems and previous hardware platform design efforts by the PNG. Essential design criteria which influenced current platform design are discussed, including special hardware features and preliminary device benchmarks. The work is concluded with the most optimal hardware platform design achieved to date, and recommendations for expansion of the developed platform.
