Farm Deaths And Injuries: Changing Farmer Attitudes And Behaviour On Farm Safety, Kieran O'Connell

Theses

While the Irish agricultural sector accounts for just 6% of the working population of Ireland, it consistently has the highest proportion of fatal incidents of any sector - generally ranging from between 35% and 45% of all workplace fatalities in any given year (Health and Safety Authority, 2015). This was again evident in 2014 where 55% (30 of the 56) of the fatal workplace incidents were in the agricultural sector (Health and Safety Authority, 2015). Agriculture has an ageing workforce with the average age of an Irish farmer now standing at fifty-seven and farmers are eight times more likely to …

Visual-Linguistic Semantic Alignment: Fusing Human Gaze And Spoken Narratives For Image Region Annotation, Preethi Vaidyanathan

Theses

Advanced image-based application systems such as image retrieval and visual question answering depend heavily on semantic image region annotation. However, improvements in image region annotation are limited because of our inability to understand how humans, the end users, process these images and image regions. In this work, we expand a framework for capturing image region annotations where interpreting an image is influenced by the end user's visual perception skills, conceptual knowledge, and task-oriented goals. Human image understanding is reflected by individuals' visual and linguistic behaviors, but the meaningful computational integration and interpretation of their multimodal representations (e.g. gaze, text) remain …

Automated Grading And Feedback Of Regular Expressions, Himesh Kakkar

Theses

To keep up with the current spread of education, there has arisen the need to have automated tools to evaluate assignments. As a part of this thesis, we have developed a technique to evaluate assignments on regular expressions (regexes). Every student is different and so is their solution, thus making it hard to have a single approach to grade it all. Hence, in addition to the existing techniques, we offer a new way of evaluating regexes. We call this the regex edit distance. The idea behind this is to find the minimal changes that we could make in a wrong …

Aligning Business Decision Making To Strategy, Donald J. Barnes, Katherine A. Dominguez, Whitney J. Vazquez

Theses

"Hurry up and wait" is a recipe for inefficiency. Some product development projects start and stop and start again, with team members being added and removed throughout the process. The cost of this lurching does not appear to be well quantified. Moving technical talent from one project to another may assume 100% engineering efficiency, which is not case. Hidden effects of engineers being moved include having to "spin up" on the new project and learn where the last team members left off (which may not be well documented), repeating initial work, and lowered efficiency and morale on the part of …

A Novel 3d Printed Leg Design For A Biped Robot, Matthew A. Haywood

Theses

This paper proposes a novel leg design for a humanoid robot that can be 3D printed. More explicitly, the efforts of this paper are to bring some of the more complex leg designs seen in large scale bipedal robot into the realm of smaller bipeds while still allowing for it to be easily reproducible or modified. In order to accomplish this 3D printing technology was utilized, as well as an iterative design process. An ankle and knee powered by linear actuators were first constructed to test the conceptual design of the leg. This was followed by a complete leg design …

Short-Term Retention Of Location-Identity Bindings For Complex Objects, Alexander Nalbandian

Theses

Knowing what is where is an essential and complex component of human perception. This ability refers to the concept of Situation Awareness (SA). The underlying mechanisms for this ability show parallels to the tracking of a set of identical objects moving on a screen, a theory known as Multiple Object Tracking (MOT) (Pylyshyn & Storm, 1988). This theory was useful for investigating the fundamental factors of visual tracking, but lacked a connection to real-world scenarios. In an attempt to bridge that gap, Oksama and Hyönä (2008) created the Model of Multiple Identity Tracking (MOMIT), which includes unique identities for each …

A Proposed Imaging System To Spatially And Temporally Monitor Unburned Hydrocarbons In Jet Engine Exhaust, Emily E. Berkson

Theses

The local air quality surrounding airports is significantly impacted by ground-based airplane operations, such as landing, taxiing, idling, and takeoff. In recent years, studies performed across the country revealed that people living near major airports suffer from increased cancer risks and higher likelihoods of developing respiratory issues. Jet engine emissions have been monitored extensively by direct probing of the exhaust, but there are currently no inexpensive, portable, and unobtrusive methods with which to study exhaust plume dynamics. This study assesses the feasibility of designing a multispectral imaging system to track the spatial-temporal nature of a jet engine plume. Ideally, the …

Implementation Of An Object-Oriented Life Cycle Assessment Framework Using Functional Analysis And Systems Engineering Principles, Shantanu Avinash Gadre

Theses

There has been a growing awareness about the environmental impacts of producing and consuming goods and services. Among the various tools that have been developed to better understand these impacts, Life Cycle Assessment (LCA) is one of the most commonly used tools to estimate the environmental effects of products and services. Given that a significant percentage of a product’s impacts are defined during the design and development, it is necessary to effectively integrate LCA into these early phases of the product lifecycle. However, the lack of standardized practices, complex modelling approaches, data and time requirements, special training requirements for designers, …

Implementation Of The Meshed Tree Algorithm On A Switched Network, Kuhu Sharma

Theses

Loop avoidance is a critical component of switched networks. Protocols like STP, RSTP, TRILL, etc solve this problem in different ways, but there is room for improvement. The Meshed Tree Protocol aims to improve the performance of switched networks while avoiding loops. In this research, a working model of the Meshed Tree Protocol (MTP) using OPNET was created. The performance of RSTP, the current industry standard, was examined and performance metrics like link failure convergence time and root failure convergence time were documented to create a baseline for further development of MTP.

Radiometrically Accurate Thermal Vehicle Targets For Synthetic Video Development, David B. Rhodes

Theses

Collecting large scientific quality thermal infrared image and video data sets is an expensive time consuming endeavor. Thermal infrared imagers cost much more than comparable visible systems and require skilled experienced operators. Also, time and experienced personnel are required to collect quality ground truth. Often it is advantageous to perform computer simulations as an alternative to collecting image and video data with real camera systems. As long as enough physics is incorporated into the models to give accurately comparable results to real imagery, simulated data can be used interchangeably. Generating synthetic images and video has the added benefit of being …

Asset Protection In Escorting Using Multi-Robot Systems, Stephen Powers

Theses

Swarm robotics is a field dedicated to the study of the design and development of certain multi-robot systems. Often times, these groups prove to be more beneficial than a single complex robot as swarms typically provide a more robust and potentially more efficient solution. One such case is the task of escorting a specified target while addressing any potential threats discovered in the environment. In this work, a control algorithm for a high volume, decentralized, homogeneous robot swarm was developed based upon a technique commonly used to model incompressible fluids known as Smoothed Particle Hydrodynamics (SPH).

This proposed solution to …

3d Subject-Atlas Image Registration For Micro-Computed Tomography Based Characterization Of Drug Delivery In The Murine Cochlea, Zhenlin Xu

Theses

A wide variety of hearing problems can potentially be treated with local drug delivery systems capable of delivering drugs directly to the cochlea over extended periods of time. Developing and testing such systems requires accurate quantification of drug concentration over time. A variety of techniques have been proposed for both direct and indirect measurement of drug pharmacokinetics; direct techniques are invasive, whereas many indirect techniques are imprecise because they rely on assumptions about the relationship between physiological response and drug concentrations. One indirect technique, however, is capable of quantifying drug pharmacokinetics very precisely: Micro-Computed tomography (micro-CT) can provide a non-invasive …

Design And Construction Of A Multispectral Camera For Spectral And Colorimetric Reproduction, Yixuan Wang

Theses

Multi-spectral imaging and spectral reflectance reconstruction can be used in cultural-heritage institutes to digitalize their collections for documentation purposes. It can be used to simulate artwork under any lighting condition, and to analyze colorants that were used. The basic idea of a multi-spectral imaging system is to sub-sample spectral reflectance factor, producing results similar to a spectrophotometer. The sampled data are used to reconstruct reflectance for the visible spectrum.

In this thesis, a wide band multispectral camera was designed and constructed to achieve high spectral and color accuracy as well as high image quality.

Noise propagation theory was introduced and …

Implementation Of The Array-Based Approach For The Evaluation Of Randomness Of The Advanced Encryption Standard (Aes), Hanadi Yahia Alomari

Theses

Randomness is critical when it comes to cryptography. When a cryptographic system has randomness in it, it is impossible to decrypt the codes and break the system. To evaluate a cryptographic function’s randomness, many statistical tests were developed such as: Diehard and ENT, but these tests are not well suited for block ciphers. CryptoStat is the best statistical test suite to test the randomness of the Advanced Encryption Standard or AES, which is a block cipher established by NIST, the National Institute of Standard and Technology. An array based approach is also used to apply the CryptoStat test suite on …

This paper presents the research and development of a flexible micro-architectural model written in SystemC for a RISC processor based upon a user defined configuration database; the RISC processor is based on an architecture assigned in course Design of Computer Systems (DCS) offered at Rochester Institute of Technology (RIT). This model will be tested by a test bench written …

Reliable Hardware Architectures For Cyrtographic Block Ciphers Led And Hight, Srivatsan Subramanian

Theses

Cryptographic architectures provide different security properties to sensitive usage models. However, unless reliability of architectures is guaranteed, such security properties can be undermined through natural or malicious faults. In this thesis, two underlying block ciphers which can be used in authenticated encryption algorithms are considered, i.e., LED and HIGHT block ciphers. The former is of the Advanced Encryption Standard (AES) type and has been considered areaefficient, while the latter constitutes a Feistel network structure and is suitable for low-complexity and low-power embedded security applications. In this thesis, we propose efficient error detection architectures including variants of recomputing with encoded operands …

Possible Past Hybridization Among Desmognathus Ochrophaeus In Canadice Lake: An Ecological Survey Exploring Desmognathine Salamanders And The Competitive Exclusion Hypothesis In The Western Finger Lakes Of New York State, Aisha L. Gadson

Theses

Dusky Salamanders are a varied group of sister taxa found in Northeastern North America. Two species, Desmognathus fuscus and Desmognathus ochrophaeus, have geographically overlapping ranges. In addition, they are very morphologically similar, share many niche requirements, and are found in extremely similar or even the same salamander communities. These shared traits have been posited to arise from the influence of niche conservatism during their species’ evolutions. Also, despite their physical similarities they are historically found not to hybridize on a large scale, nor have ever had a full population merge recorded. Therefore, it appears that the community ecology of these …

Hierarchical Decomposition Of Large Deep Networks, Sumanth Chennupati

Theses

Teaching computers how to recognize people and objects from visual cues in images and videos is an interesting challenge. The computer vision and pattern recognition communities have already demonstrated the ability of intelligent algorithms to detect and classify objects in difficult conditions such as pose, occlusions and image fidelity. Recent deep learning approaches in the ImageNet Large Scale Visual Recognition Challenge (ILSVRC) are built using very large and deep convolution neural network architectures. In 2015, such architectures outperformed human performance (94.9% human vs 95.06% machine) for top-5 validation accuracies on the ImageNet dataset, and earlier this year deep learning approaches …

The Uncanny Valley The Effect Of Removing Blendshapes From Facial Animation, Ameya Lonkar

Theses

Ever since its introduction in 1970 by the roboticist Dr. Mori, the uncanny valley has become an integral part of facial animation. While most of the work on the uncanny valley is focused on finding a way to surpass the uncanny valley and how certain things could be designed to increase or decrease the uncanniness of an animation, this paper investigates how removing certain blendshapes from the facial animation changes our perception about the eeriness of that animation. The goal is to identify the “necessary” blendshapes which bring about a significant change the perceived uncanniness of the animation. For achieving …

Developing A Measurement System To Assess Line Profile Retention In 3d Printing, Heng Li

Theses

Manufacturing three-dimensional (3D) objects with methods adapted from conventional digital printing have propelled the development of additive manufacturing. In this process, the printing devices directly deposit or fuse materials to form 3D solid objects in a layer-by-layer fashion, thereby creating the additive approach of fabrication.

As additive manufacturing (AM) has been increasingly adopted for rapid prototyping and part manufacturing, the need to determine the part quality which results from the processes becomes crucial (Monzón, Ortega, Martínez, & Ortega, 2015). There is a lack of quantifiable measurement systems to define a printer’s ability to resolve systematic and geometric features and dimensionalities …

Heart Valve Mathematical Models, Paula Kolar

Theses

Nearly 100,000 heart valve replacements or repairs are performed in the US every year. Mathematical models of heart valves are used to improve artificial valve design and to guide surgeons performing valve-repairing surgeries. Models can be used to define the geometry of a valve, predict blood flow dynamics, or demonstrate operating mechanisms of the valve. In this thesis we reviewed features that are typically considered when developing a model of a heart valve. The main modeling methods include representing a heart valve using lumped parameters, finite elements, or isogeometric elements. Examples of a lumped-parameter model and isogeometric analysis are explored. …

Relationship Between Velocity Of Contraction And Force Applied On Air Muscles, Aniruddha Sudhir Phatak

Theses

Air muscles are simple pneumatic devices that have high potential to be used as robotic manipulators, as they have a behavior similar to biological motors or muscles. Hence, they have a wide range of potential applications in areas such as robotics, bio-robotics, biomechanics, and artificial limb replacements. In addition to the similarity to biological muscle, air muscles have the advantages of good power-to-weight ratio, being compliant, and low cost. This thesis primarily quantifies the relationship between velocity of contraction of air muscles and the force applied on it, which is a key characteristic of biological skeletal muscle. First, an experimental …

Lightweight Architectures For Reliable And Fault Detection Simon And Speck Cryptographic Algorithms On Fpga, Prashant Ahir

Theses

The widespread use of sensitive and constrained applications necessitates lightweight (lowpower and low-area) algorithms developed for constrained nano-devices. However, nearly all of such algorithms are optimized for platform-based performance and may not be useful for diverse and flexible applications. The National Security Agency (NSA) has proposed two relatively-recent families of lightweight ciphers, i.e., Simon and Speck, designed as efficient ciphers on both hardware and software platforms. This paper proposes concurrent error detection schemes to provide reliable architectures for these two families of lightweight block ciphers. The research work on analyzing the reliability of these algorithms and providing fault diagnosis approaches …
