A Study Of Deep Learning Silhouette Extractors For Gait Recognition, Sneha Oladhri

USF Tampa Graduate Theses and Dissertations

Gait recognition has gained importance in biometrics for identifying a person. It is performed by analyzing the gait features extracted from a video of a walking person. Gait features can be represented using silhouettes, pose elements, 3d human body features, or the combination of any of the above features. Most gait recognition algorithms use silhouette data for modeling. Therefore the quality of the silhouettes is crucial for achieving better recognition results. Many previous works have used the silhouettes given with the dataset for developing a gait model. In this work, we will test the performance of different background subtraction algorithms …

Corrosion Rate Prediction In Frp-Concrete Repair, Mohammad A. Khawaja

USF Tampa Graduate Theses and Dissertations

Research has proven that wrapping structural elements with fiber-reinforced polymers (FRPs) slows down chloride-induced corrosion rate but does not stop it. Although FRP has been used for corrosion repair for over 40 years, predictive corrosion rate models for FRP-concrete systems are limited in literature. This dissertation presents an oxygen diffusion-based predictive framework to estimate corrosion rate in FRP-concrete systems.

The dissertation has three main components. First, a core framework that is referred to as Khawaja-Sen-Bhethanabotla (KSB) model. In the KSB model, statistical methods were used to extend experimental data on oxygen permeation coefficients. These data were for one and two …

Neurovascular Catheter Measurement System Development For Process And Design Effect Evaluation, Cathal Tadhg Merz

Theses

Neurovascular guide catheters are used to treat problems affecting blood vessels within the brain through minimally invasive procedures. Catheters are inserted into the patient via their femoral or brachial arteries and manually navigated to the brain to deliver treatment. This procedure replaces the requirement to cut into the patient’s skull and brain tissue but is limited by reduction of blood vessel lumen diameter and increase in tortuosity of blood vessels deep in the brain. During these procedures, catheters can sometimes fail by kinking or fracturing into two pieces. The rate of failure by fracture of a particular neurovascular catheter device …

Full-Scale Study Of Infrared Thermography For Assessing Surface And Subsurface Defects In Pavements And Other Civil Infrastructure, Aidin J. Golrokh

Boise State University Theses and Dissertations

Infrared thermography (IRT) is an effective non-destructive testing method in the field of concrete and asphalt pavements inspection. IRT is used to have an initial evaluation of the surface and near surface of pavements in a very time effective manner compared to other types of nondestructive testing (NDT) methods. Different aspects of IRT and its use to assess surface and subsurface defects in different types of pavements are being studied and evaluated in our research group. The effect of the depth of delamination inside concrete pavement on IRT technique is being studied. It is suggested by our group that there …

Evaluación Del Efecto De La Harina De Semilla De Moringa Como Coadyudante En El Proceso De Coagulación Para El Tratamiento De Aguas Residuales Provenientes Del Proceso De Pelambre De Una Curtiembre En Bogotá, Juan David Baldion Bonilla, Harold Steven Perea

Ingeniería Ambiental y Sanitaria

La industria del curtido es una de las industrias más antiguas, su alta complejidad se caracteriza porque sus vertimientos tienen una alta DBO, DQO, sólidos suspendidos, sólidos sedimentables, sulfuros, cloruros y cromo, lo cual la convierten en una de las industrias más contaminantes y que mayor impacto ambiental causa sobre suelos y aguas. La coagulación- floculación es una de las técnicas en el tratamiento fisicoquímico más importante utilizada en la industria de curtiembres para poder reducir los materiales suspendidos y coloidales responsables de la turbidez de las aguas residuales. Durante la última década, se ha dado un mayor interés al …

Recovery Of Nutrients From Anaerobically Digested Enhanced Biological Phosphorus Removal (Ebpr) Sludge Through Struvite Precipitation, Maraida Balaguer-Barbosa

USF Tampa Graduate Theses and Dissertations

Water resources in Florida have been severely degraded by eutrophic conditions, resulting toxic algae blooms, which negatively affect health and tourism. Eutrophication, or excessive amount of phosphorus (P) and nitrogen (N) in water, overstimulates the production of aquatic plants, depletes dissolved oxygen, and deteriorates the aquatic environment. However, phosphorus is a non-renewable resource essential for all living organisms. In fact, more than half of the total demand for P globally is to supply the food industry, which has concerningly accelerated the depletion rates of phosphate reserves.

In many wastewater treatment plants (WWTPs), the enhanced biological phosphorus removal (EBPR) approach has …

Experimental Investigation Of Reading Passive Uhf Tags In A Multi-Tag Environment, Yi Zhou

Theses and Dissertations--Mechanical Engineering

Recently, the Internet of things (IoT) has emerged as a promising solution for several industrial applications. One of the key components in IoT is passive radio frequency identification (RFID) tags which do not require a power source for operations. Specifically, ultra-high frequency (UHF) tags are studied in this paper. However, due to factors such as tag-to-tag interference and inaccurate localization, RFID tags that are closely spaced together are difficult to detect and program accurately with unique identifiers. This thesis investigates several factors that affect the ability to encode a specific tag with unique information in the presence of other tags, …

Evaluating The Impacts Of The Internet Of Things To Reduce Runway Incursions: Understanding The Why, How, And When, Samuel Inanore Okate

Industrial, Manufacturing, and Systems Engineering Dissertations

The Federal Aviation Administration’s (FAA) mission is to maintain the safest and most efficient aerospace system in the world. The FAA has stated that runway safety is one of their top priorities, which encapsulates pilots, air traffic controllers, and airport vehicle drivers and workers (Federal Aviation Administration, June 2015). Federal Aviation Administration categorizes a runway incursion as a hazardous event that can occur in the Air Operations Area (AOA) that involves an incorrect presence of an aircraft, vehicle or person in the protected area of a surface designated for the landing and takeoff of an aircraft (Federal Aviation Administration, June …

Optimisation Of The Transesterification Stage Of Biodiesel Production Using Statistical Methods, Arnold Paintsil

Electronic Thesis and Dissertation Repository

The present research examines solely the transesterification stage of the biodiesel production process. Six process variables that affect the yield of biodiesel at this stage are examined using the 12 run Plackett-Burman Design. To study the effect of FFA[1] and to replicate real life situations where oil (feedstock) contain varying amounts of FFA, linoleic acid is used as FFA and intentionally added to high oleic acid canola oil containing less than 0.07% FFA. The process is catalyzed with potassium carbonate and evaluated at varying temperatures, stirring rates, reaction times and methanol oil ratios. The yields at the end of …

Designing And Setting Up A Process For Assessing Measurement System's Capability, Kiran Namala

Culminating Projects in Mechanical and Manufacturing Engineering

Measurement Systems Analysis is a methodology applied to measure the amount of variation in the measurement device. The purpose of conducting the MSA study is to quantify measurement error and to reduce the measurement variation to the maximum possible extent. The study is pursued by referring to various quality control books, papers and experts in this area. Potential problems related to the measurement device (if they exist) would be exposed after this study and recommendations would be made in order to achieve a successful quality improvement.
