Sensor-Driven Hierarchical Path Planning For Unmanned Aerial Vehicles Using Canonical Tasks And Sensors, Spencer James Clark Sep 2013

Sensor-Driven Hierarchical Path Planning For Unmanned Aerial Vehicles Using Canonical Tasks And Sensors, Spencer James Clark

Theses and Dissertations

Unmanned Aerial Vehicles (UAVs) are increasingly becoming economical platforms for carrying a variety of sensors. Building flight plans that place sensors properly, temporally and spatially, is difficult. The goal of sensor-driven planning is to automatically generate flight plans based on desired sensor placement and temporal constraints. We propose a simple taxonomy of UAV-enabled sensors, identify a set of generic sensor tasks, and argue that many real-world tasks can be represented by the taxonomy. We present a hierarchical sensor-driven flight planning system capable of generating 2D flights that satisfy desired sensor placement and complex timing and dependency constraints. The system makes …


Human-Swarm Interaction: Effects On Operator Workload, Scale, And Swarm Topology, Brian O. Pendleton Sep 2013

Human-Swarm Interaction: Effects On Operator Workload, Scale, And Swarm Topology, Brian O. Pendleton

Theses and Dissertations

Robots, including UAVs, have found increasing use in helping humans with dangerous and difficult tasks. The number of robots in use is increasing and is likely to continue increasing in the future. As the number of robots increases, human operators will need to coordinate and control the actions of large teams of robots. While multi-robot supervisory control has been widely studied, it requires that an operator divide his or her attention between robots. Consequently, the use of multi-robot supervisory control is limited by the number of robots that a human or team of humans can reasonably control. Swarm robotics -- …

Graphstore: A Distributed Graph Storage System For Big Data Networks, Venkataswamy Martha

Theses and Dissertations

Networks, such as social networks, are a universal solution for modeling complex problems in real time, especially in the Big Data community. While previous studies have attempted to enhance network processing algorithms, none have paved a path for the development of a persistent storage system. The proposed solution, Graphstore, provides an efficient and scalable graph management system for giant networks using Hadoop, a widely accepted distributed big data processing framework. Unlike the existing graph processing systems on Hadoop, the GraphStore offers a persistency through which query processing modules can be implemented. There arise several challenges with this study, such as …


Dynamical System Approach To System Call Analysis For Host Based Intrusion Detection, Nitin Vishwanath Kanaskar Aug 2013

Dynamical System Approach To System Call Analysis For Host Based Intrusion Detection, Nitin Vishwanath Kanaskar

Theses and Dissertations

Worms and remote intrusions often utilize code injection to be successful. Execution of the injected code is crucial to exploit a vulnerability in an application. This proposal introduces a different approach than the previous approaches to system call analysis. System call layer reflects significant behavioral semantics of an application as it signifies change of application privileges to kernel mode. We introduce some of the well-established techniques and formalisms of Dynamical System Theory into analysis of application behavior via system calls analysis. We accept a program as a blackbox dynamical system whose internals are not known but whose output - system …


Low-Profile Wake-Up Radio Mechanism For Resource-Constrained Wireless Devices, Ali Al-Uraiby Aug 2013

Low-Profile Wake-Up Radio Mechanism For Resource-Constrained Wireless Devices, Ali Al-Uraiby

Theses and Dissertations

Achieving low power consumption, size reduction, and space optimization are all challenges in resource constrained wireless devices such as Wireless Sensor Network (WSN) nodes. WSN nodes use duty cycle to improve their power efficiency, and wake-up radio (WUR) is used as a control channel to wake them up. A field-programmable gate array (FPGA) is one of the attractive candidates for WSN devices implementation. A low-profile WUR scheme is proposed and implemented using FPGA to address the challenge of power consumption for resource-constrained wireless devices. First, a new design to partition WUR from the remaining main radio component and data processing …

Practical Cost-Conscious Active Learning For Data Annotation In Annotator-Initiated Environments, Robbie A. Haertel

Theses and Dissertations

Many projects exist whose purpose is to augment raw data with annotations that increase the usefulness of the data. The number of these projects is rapidly growing and in the age of “big data” the amount of data to be annotated is likewise growing within each project. One common use of such data is in supervised machine learning, which requires labeled data to train a predictive model. Annotation is often a very expensive proposition, particularly for structured data. The purpose of this dissertation is to explore methods of reducing the cost of creating such data sets, including annotated text corpora.We …

User Experience Engineering (UxE) incorporates subject areas like usability, HCI, interaction experience, interaction design, "human factors", ergonomics", cognitive psychology", behavioral psychology and psychometrics", systems engineering", [and] "computer science," (Hartson, 1998). It has been suggested that UxE will be the main success factor in organizations as we enter the "loyalty decade" of software development, where the repeat usage of a product by a single customer will be the metric of product success (Alghamdi, 2010; Law & van Schaik, 2010, p. 313; Nielsen, 2008; Van Schaik & Ling, 2011). What is relatively unknown in the current academic literature is whether existing UxE …


Dynamic Near Field Communication Pairing For Wireless Sensor Networks, Steven Charles Cook Jul 2013

Dynamic Near Field Communication Pairing For Wireless Sensor Networks, Steven Charles Cook

Theses and Dissertations

Wireless sensor network (WSN) nodes communicate securely using pre-installed cryptographic keys. Although key pre-installation makes nodes less expensive, the technical process of installing keys prevents average users from deploying and controlling their own WSNs. Wireless pairing enables users to set up WSNs without pre-installing keys, but current pairing techniques introduce numerous concerns regarding security, hardware expense, and usability. This thesis introduces dynamic Near Field Communication (NFC) pairing, a new pairing technique designed for WSNs. This pairing overcomes the limitations of both key pre-installation and current pairing techniques. Dynamic NFC pairing is as secure as using pre-installed keys, requires only inexpensive …


Assessment And Prediction Of Cardiovascular Status During Cardiac Arrest Through Machine Learning And Dynamical Time-Series Analysis, Sharad Shandilya Jul 2013

Assessment And Prediction Of Cardiovascular Status During Cardiac Arrest Through Machine Learning And Dynamical Time-Series Analysis, Sharad Shandilya

Theses and Dissertations

In this work, new methods of feature extraction, feature selection, stochastic data characterization/modeling, variance reduction and measures for parametric discrimination are proposed. These methods have implications for data mining, machine learning, and information theory. A novel decision-support system is developed in order to guide intervention during cardiac arrest. The models are built upon knowledge extracted with signal-processing, non-linear dynamic and machine-learning methods. The proposed ECG characterization, combined with information extracted from PetCO2 signals, shows viability for decision-support in clinical settings. The approach, which focuses on integration of multiple features through machine learning techniques, suits well to inclusion of multiple physiologic …

Motion Artifact Reduction In Impedance Plethysmography Signal, Sardar Ansari Jun 2013

Motion Artifact Reduction In Impedance Plethysmography Signal, Sardar Ansari

Theses and Dissertations

The research related to designing portable monitoring devices for physiological signals has been at its peak in the last decade or two. One of the main obstacles in building such devices is the effect of the subject's movements on the quality of the signal. There have been numerous studies addressing the problem of removing motion artifact from the electrocardiogram (ECG) and photoplethysmography (PPG) signals in the past few years. However, no such study exists for the Impedance Plethysmography (IP) signal. The IP signal can be used to monitor respiration in mobile devices. However, it is very susceptible to motion artifact. …


Inverted Sequence Identification In Diploid Genomic Scaffold Assembly Via Weighted Max-Cut Reduction, Paul Mark Bodily Jun 2013

Inverted Sequence Identification In Diploid Genomic Scaffold Assembly Via Weighted Max-Cut Reduction, Paul Mark Bodily

Theses and Dissertations

Virtually all genome assemblers to date are designed for use with data from haploid or homozygous diploid genomes. Their use on heterozygous genomic datasets generally results in highly-fragmented, error-prone assemblies, owing to the violation of assumptions during both the contigging and scaffolding phases. Of the two phases, scaffolding is more particularly impacted and algorithms to facilitate the scaffolding of heterozygous data are lacking. We present a stand-alone scaffolding algorithm, ScaffoldScaffolder, designed specifically for scaffolding diploid genomes. A fundamental step in the scaffolding phase is the assignment of sequence orientations to contigs within scaffolds. Deciding such an assignment in the presence …


Interactive Depth-Aware Effects For Stereo Image Editing, Joshua E. Abbott Jun 2013

Interactive Depth-Aware Effects For Stereo Image Editing, Joshua E. Abbott

Theses and Dissertations

This thesis introduces methods for adding user-guided depth-aware effects to images captured with a consumer-grade stereo camera with minimal user interaction. In particular, we present methods for highlighted depth-of-field, haze, depth-of-field, and image relighting. Unlike many prior methods for adding such effects, we do not assume prior scene models or require extensive user guidance to create such models, nor do we assume multiple input images. We also do not require specialized camera rigs or other equipment such as light-field camera arrays, active lighting, etc. Instead, we use only an easily portable and affordable consumer-grade stereo camera. The depth is calculated …


Patchmatch-Based Content Completion Of 3d Images, Joel Arthur Howard Jun 2013

Patchmatch-Based Content Completion Of 3d Images, Joel Arthur Howard

Theses and Dissertations

This thesis presents a method for completing target regions ("hole filling") in RGB stereo pairs. It builds upon the state of the art for completing single images by matching to and then blending source patches drawn from the rest of the image. A method is introduced for first completing the respective disparity maps using a coupled partial differential equation based on that of Bertalmio, et al. extended to create mutual disparity consistency. Estimated disparities are then used to guide completion of the missing color image texture. An extension to the coherence-based objective function introduced by Wexler, et al. is then …
