Adaptive Live Video Streaming By Priority Drop, Jie Huang, Charles Krasic, Jonathan Walpole

Computer Science Faculty Publications and Presentations

In this paper we explore the use of Priority-progress streaming (PPS) for video surveillance applications. PPS is an adaptive streaming technique for the delivery of continuous media over variable bit-rate channels. It is based on the simple idea of reordering media components within a time window into priority order before transmission. The main concern when using PPS for live video streaming is the time delay introduced by reordering. In this paper we describe how PPS can be extended to support live streaming and show that the delay inherent in the approach can be tuned to satisfy a wide range of …

Model State Land Use Legislation For New England, New England Environmental Finance Center, Muskie School Of Public Service

Legislation

Sprawl is neither the ordained nor the inevitable outcome upon the New England landscape. A coordinated response to sprawl by the public and private sectors is possible, and could dramatically improve land use patterns and reduce the cost of local government. For the New England states, such a response would include, among other elements, legislation to eliminate existing gaps in the land use laws of each state – gaps that presently encourage or sanction sprawling development. It would also include incentives for municipalities to think beyond their borders and to act with greater efficiency and effect. It is the purpose …

Investigating The Effects Of The Mission Status Graphics Polar Star Display On Failure Detection Time And Situation Awareness For Mission And System Monitoring In General Aviation Aircraft, Anthony P. Bartolone

Master's Theses - Daytona Beach

For years, the aviation industry has been under severe scrutiny over the safety of flight when cockpit automation is over relied on and when it is under utilized. This double-edged sword raises the question of situation awareness in aviation. With the recent boom in cockpit automation and advanced avionics some fear that the pilots are being put outside "the loop". Unfortunately, humans are notoriously poor monitors of reliable systems over time. However, research is currently being conducted into a new form of display that has the ability to group a myriad of aircraft mission and system status information onto one …

The Effect Of An Unconscious Auditory Stimulus On Pilot Performance Under Varying Instrument Flying Conditions, Christina Eleni Christakou

Master's Theses - Daytona Beach

Human error remains a significant contributing factor with respect to accidents in civil air transportation. It is therefore crucial to establish avenues by which performance on the flightdeck can be enhanced under conditions of distress. The purpose of this study was to examine whether an unconscious auditory stimulus (UAS) could enhance pilot performance under varying instrument flight (IFR) conditions on the aircraft flightdeck. Forty IFR student pilots underwent two eight-minute simulated flights, whereupon they were presented with different IFR weather conditions. During the trial, the experimental group listened to a UAS, whereas the control group listened to white noise (WN). …

A System Dynamics Model Of The Pacific Coast Rockfish Fishery, Wayne Wakeland, Olgay Cangur, Guillermo Rueda, Astrid Scholz

Complex Systems Faculty Publications and Presentations

This paper presents a model of the dynamic behavior of the yellowtail rockfish of the Pacific Coast of the United States. The purpose of the model is to generate endogenously the historical data for fish population, fishing vessels, regulatory parameters, and fish harvest. The model was subjected to a variety of tests to determine its sensitivity to changes in key parameters and initial values, including extreme conditions.

Applicability Of Risk-Based Management And The Need For Risk-Based Economic Decision Analysis At Hazardous Waste Contaminated Sites, I. Khadam, Jagath J. Kaluarachchi

Civil and Environmental Engineering Faculty Publications

Decision analysis in subsurface contamination management is generally carried out through a traditional engineering economic viewpoint. However, new advances in human health risk assessment, namely, the probabilistic risk assessment, and the growing awareness of the importance of soft data in the decision-making process, require decision analysis methodologies that are capable of accommodating non-technical and politically biased qualitative information. In this work, we discuss the major limitations of the currently practiced decision analysis framework, which evolves around the definition of risk and cost of risk, and its poor ability to communicate risk-related information. A demonstration using a numerical example was conducted …

Piezoelectric Sensor In The Application Of Rolling Bearing Health Monitoring, Yinyin Liu

Mechanical & Aerospace Engineering Theses & Dissertations

A condition-based monitoring concept for rolling element bearings in machinery utilizing a piezoelectric load sensor is investigated in this thesis. The radially polarized cylindrical piezoelectric sensor is modeled in its specific coordinates. The sensor registers the stress occurring in all directions around it. The sensor's behavior due to several typical loads is analyzed. Based on the induced stresses in the sensor, the sensor's output as an electric charge can be obtained using the method of integration.

Considering both the normal and tangential loads distributed on the rolling beating's roller-raceway contact surface, the dynamic stress distribution in the outer raceway was …

Paper On Measurement Of The Nanomechanical Properties Of Thin Films Using Afam Receives Recognition, Donna Hurley, Joseph A. Turner, Paul Rice, Joshua Wiehn

Department of Engineering Mechanics: Faculty Publications

NIST researchers are developing atomic force acoustic microscopy (AFAM) methods to quantitatively determine the elastic properties of thin films. The AFAM technique measures the frequencies of an atomic force microscope (AFM) cantilever’s first two flexural resonances while in contact with a material. The indentation modulus, M, of an unknown or test material can then be obtained by comparing the resonant spectra of the test material to those of a reference material. To examine metrology issues for this emerging technique, AFAM results have been compared with those obtained by other methods, such as instrumented indentation. The results show that better agreement …

Utilization Of Municipal Solid Waste Rejects In The Production Of A Recycled Plastic Waste Composite Material, Mohamed Kamal Abou Khatwa

Archived Theses and Dissertations

The solid waste disposal problem has grown significantly in the last decades imposing a lot of pressure on disposal and treatment acts. In the past, incineration and landfilling were the common methods for disposing of products of municipal solid waste. With the increasing volumes of waste generation and the legislative restrictions of these treatment methods, reuse of bulk waste is foreseen as the best alternative to disposal. Due to the current widespread use of plastic products in daily life, post consumer plastics now contribute significantly to municipal solid waste generation rates with a contradicting low participation in waste minimization practices. …
