Development Of An Algorithm For Satellite Remote Sensing Of Sea And Lake Ice, Peter Dorofy

Theses and Dissertations

Satellite remote sensing of snow and ice has a long history. The traditional method for many snow and ice detection algorithms has been the use of the Normalized Difference Snow Index (NDSI). This manuscript is composed of two parts. Chapter 1, Development of a Mid-Infrared Sea and Lake Ice Index (MISI) using the GOES Imager, discusses the desirability, development, and implementation of alternative index for an ice detection algorithm, application of the algorithm to the detection of lake ice, and qualitative validation against other ice mapping products; such as, the Ice Mapping System (IMS). Chapter 2, Application of Dynamic Threshold …

The Significance Of A High Resolution 2d Hydraulic Model Including Green Infrastructure For Assessment Of Coastal Community Vulnerability And Resilience, Katie M. Miller

Theses and Dissertations

This paper outlines the development of an enhanced hydraulic flood model that uses a fine-scale grid to analyze significant areas of flooding for improved flood predictions and resiliency planning. This study modeled the extent of Atlantic City and Camden, New Jersey. The capabilities of the model were compared to coarser national models, HAZUS-MH and SLOSH, to understand the significance of fine-scale hydraulic modeling. The results illustrated that the HAZUS and SLOSH models showed gaps in some areas and lacked accuracy due to lower resolution. This paper also describes how these developed models show the impacts of severe storms, and the …

Evaluating The Impact Of Different Types Of Stabilized Bases On The Overall Performance Of Flexible Pavements, Andrae Anthony Francois

Theses and Dissertations

This study was initiated with the aim of evaluating the impact of stabilized and untreated base layers on the performance (i.e., fatigue and rutting) of flexible pavements. Four field sections constructed using stabilized base layers (i.e., bituminous (asphalt emulsion), calcium chloride (CaCl-2), Portland cement, and geogrid stabilized base layers) and a control section constructed using untreated RAP aggregates were analyzed in this study. Falling Weight Deflectometer (FWD) tests were conducted on all the field sections and the collected data was used to backcalculate the elastic moduli for all layers. The influence of the stabilized bases and the untreated RAP base …

Analysis Of Aggregate Mineralogy Using Libs, Bless Ann Varghese

Theses and Dissertations

The New Jersey Department of Transport (NJDOT) has a vested interest in the determination of the chemical composition and thereby the mineralogy of aggregates. Depending on the mineralogy of an aggregate sample, it may be inappropriate to use for construction and roadwork purposes. Current methods of determining the mineralogy of aggregates are costly in terms of time, money and convenience. As such, there is a desire for the development of an alternative and efficient method for aggregate mineralogical determination in the field.

The focus of this study is to develop a portable system for aggregate analysis in the field and …

Structural Strength Evaluation And Retrofitting Of Hangar Q At Millville Airport, Harshdutta Indradutta Pandya

Theses and Dissertations

Hangar Q was built in Millville, New Jersey as a part of the Home Defense Program of World War II. The airport is now owned and operated by the Delaware River and Bay Authority (DRBA) as the Millville Airport. Hangar Q was a historic nine-bow truss hangar when it was first constructed, standing at 30 feet high, 130 feet wide, and 160 feet deep. It was originally constructed with no side walls and no back wall or front roll-up doors. It was later updated from a completely open design to a closed design. The objective of this study was to …
