Parallel Compositing Of Multi-Temporal Satellite Imagery Using Temporal Map Algebra, Bijay Shrestha

Theses and Dissertations

Spatio-temporal satellite image analysis is a technique for monitoring spatial and temporal changes of land cover and oceanic locations on earth. Temporal Map Algebra (TMA) is a novel technique developed by Jeremy Mennis and Roland Viger for analyzing a time series of satellite imagery using simple algebraic operators that treats time series of imagery as a threedimensional data set, where two dimensions encode planimetric position on earth surface and the third dimension encodes time. The high dimensionality of raster data leads to high computational cost, which is why parallel computation is attractive. This thesis describes the design, implementation, andmperformance evaluation …

Exploring Extensions Of Traditional Honeypot Systems And Testing The Impact On Attack Profiling, Robert Wesley Mcgrew

Theses and Dissertations

This thesis explores possibilities for extending the features of honeypot systems to decrease the chance of an attacker discovering that they have compromised a honeypot. It is proposed that by extending the period of time that an attacker spends on a honeypot oblivious to its status, more information relevant to profiling the attacker can be gained. Honeypots are computer systems that are deployed in a way that attackers can easily compromise them. These systems, which contain no production data, are useful both as early warning systems for attacks on production systems, and for studying the tools, techniques, and motives of …

An Approach To Graph-Based Modeling Of Network Exploitations, Wei Li

Theses and Dissertations

Computer security professionals and researchers are investigating proactive techniques for studying network-based attack behavior. Attack modeling is one of these research areas. In this dissertation, we address a novel attack modeling technique called an exploitation graph (e-graph) for representing attack scenarios. The key assumption in this research is that we can use exploitation graphs to represent attack scenarios, and methods involving e-graphs can be applied to provide vulnerability mitigation strategies. The modeling process consists of three primary steps. The first step is the creation of a knowledge base of vulnerability graphs (v-graphs) from known system vulnerabilities. Each v-graph shows necessary …

Critical Properties Of Small World Ising Models, Xingjun Zhang

Theses and Dissertations

In this dissertation, the critical scaling behavior of magnetic Ising models with long range interactions is studied. These long range interactions, when imposed in addition to interactions on a regular lattice, lead to small-world graphs. By using large-scale Monte Carlo simulations, together with finite-size scaling, the critical behavior of a number of different models is obtained. The Ising models studied in this dissertation include the z-model introduced by Scalettar, standard small-world bonds superimposed on a square lattice, and physical small-world bonds superimposed on a square lattice. From the scaling results of the Binder 4th order cumulant, the order parameter, and …

A Study On The Split Delivery Vehicle Routing Problem, Kai Liu

Theses and Dissertations

This dissertation examines the Split Delivery Vehicle Routing Problem (SDVRP), a relaxed version of classical capacitated vehicle routing problem (CVRP) in which the demand of any client can be split among the vehicles that visit it. We study both scenarios of the SDVRP in this dissertation. For the SDVRP with a fixed number of the vehicles, we provide a Two-Stage algorithm. This approach is a cutting-plane based exact method called Two-Stage algorithm in which the SDVRP is decomposed into two stages of clustering and routing. At the first stage, an assignment problem is solved to obtain some clusters that cover …

Identification And Location Of Sunken Logs Using Sidescan Sonar Technology, Aravindh Srivatsav Ravichandran

Theses and Dissertations

Identifying the location of sunken logs is a task of considerable interest in today?s world economy. The main motive of this work is to find and locate sunken cypress logs that were lost during the transit to a lumber mills. Underwater logging is possible because of the fact that many of the logs were barely affected by the decades of submersion. Cypress logs, the types of logs used in this research have a natural resistant to rotting. The other probability for the logs not being affected significantly, even staying in water for decades, is the high density of the growth …

Development Of An Improved On-Line Voltage Stability Index Using Synchronized Phasor Measurement, Yanfeng Gong

Theses and Dissertations

Recent events, such as the Northeast Blackout of 2003, have highlighted the need for accurate real-time stability assessment techniques to detect when an electric power system is on the brink of voltage collapse. While many techniques exist, most techniques are computationally demanding and cannot be used in an on-line application. A voltage stability index (VSI) can be designed to estimate the distance of the current operating point to the voltage marginally stable point during the system operation. In this research work, a new VSI was developed that not only can detect the system voltage marginally stable point but also is …

Development Of Conjugate Heat Transfer Capability To An Unstructured Flow Solver - U2ncle, Qingluan Xue

Theses and Dissertations

A precise prediction of the heat loads in metal materials in contact with the hot gas is an increasingly demanding problem in the design phase of the complex cooling schemes in the modern turbine engines. The coupled calculation of the fluid flow and the heat transfer is a promising approach as heat transfer coefficients are not necessary in the calculation and the heat transfer itself is part of the calculation and can be derived from local heat fluxes. Therefore, it is useful to incorporate an appropriate scheme for directly coupled heat transfer computations (conjugate heat transfer), capable of handling complex …

Development Of A Supersonic Wind Tunnel Rapid Real-Time Data Acquisition And Control System, Ndubuisi Emmanuel Okoro

Theses and Dissertations

As a part of the revitalization of the supersonic wind tunnel maintained by the Aerospace Engineering Department of Mississippi State University, a new data acquisition and control system became incumbent. Previous data acquisition and control systems used in the operation of the supersonic wind tunnel made use of now outdated hardware and functioned with two central processing units; one processor was used for recording system response, while the other monitored and controlled the tunnel. A new system is required to provide adequate rapid real-time control, along with rapid acquisition of raw tunnel feedback or response data and tunnel pressure data …

Fast Reconfiguration Algorithm Development For Shipboard Power Systems, Yan Huang

Theses and Dissertations

Todays protection schemes for shipboard applications, such as the zone-based differential protection, are efficient, fast, and reliable for fault detection. However, these protection schemes do not consider the system stability or power balance problems that occur with fault isolation and the system reconfiguration. This thesis focuses on developing the extended protection function including the fast reconfiguration function that intends to maintain the power balance of the unfaulted subsystem. Graph theory is utilized to represent the shipboard power system topology in matrices, and matrix operations are developed to represent the corresponding power system topology change and evaluate the outcome of the …

Work Replication: A Communication Optimization For Loci, Krunal Navinchandra Soni

Theses and Dissertations

For distributed memory architectures, communication cost is a significant source of overhead in parallel scientific applications. Many proposed communication optimizations duplicate the behavior of well-written hand-tuned parallel code. Because of continuous changes in architectural components, these types of low-level optimizations are not always effective. This thesis seeks to develop a high-level optimization of work replication in which computations are replicated to minimize communications. There exist performance trade-offs between computation cost and communication cost because of work replication. Due to these trade-offs, it is required to determine which computations should be replicated to improve overall performance. This research presents the development …

Critical Analysis Of Sic Sit Design And Performance Based Upon Material And Device Properties, Yunmo Sung

Theses and Dissertations

Recently, the need for high power, high frequency devices continues to grow with the increase in wireless communication, radar systems, HDTV, digital communication, and other military application of the RF spectrum. Traditionally when higher power is needed, one needs to either combine the output power of multiple devices or use vacuum tubes, which are still uncontested at very high power levels, capable of up to a few hundred kilowatts at 5 GHz [11]. But wide band gap semiconductor devices capable of competing in this application. Moreover, the static induction transistor (SIT) in silicon carbide can provide very high total power …

Definition, Analysis, And An Approach For Discrete-Event Simulation Model Interoperability, Tai-Chi Wu

Theses and Dissertations

Even though simulation technology provides great benefits to industry, it is largely underutilized. One of the biggest barriers to utilizing simulation is the lack of interoperability between simulation models. This is especially true when simulation models that need to interact with each other span an enterprise or supply chain. These models are likely to be distributed and developed in disparate simulation application software. In order to analyze the dynamic behavior of the systems they represent, the models must interoperate. However, currently this interoperability is nearly impossible. The interaction of models also refers to the understanding of them among stakeholders in …

The study will compare the persuasiveness of different online recommender systems and the factors influencing customer preferences. Review of the literature does show that online recommender systems provide customers …

An Investigation Of Firms' Earnings Management Practices Around Product Recalls, Zeeshan Ahmed

Theses and Dissertations

This study investigates the earnings management practices of firms around product recalls. In recent years, the management of earnings around firm-specific events has received considerable attention in the finance and accounting literature. New equity issues, mergers and acquisitions, share repurchases, and management buyouts are some events around which at least some firms have been shown to manage their earnings to achieve managements? objectives. Product recalls offer yet another interesting occasion when managers have incentives to cover up the true financial performance of their firms and mislead investors. In order to determine whether firms announcing product recalls manage earnings more aggressively …

Testing The Floristic Quality Assessment Index In Natural And Created Wetlands In Mississippi, Usa, Brook Danielle Herman

Theses and Dissertations

The U.S. Environmental Protection Agency has mandated that states must include the use of biological assessments in their water quality laws to assess the biological integrity of aquatic systems. The Floristic Quality Assessment Index (FQAI), which uses wetland vegetation to assess the biological integrity of an ecosystem, has not been tested in Mississippi. The purpose of this study was to test the efficiency of the FQAI in wetlands along a gradient of human influence. Coefficients of conservatism (CC) were assigned to plant species based on their tolerance to disturbance and fidelity to habitat. A negative correlation was found between the …

Individualistic Roamers Or Community Builders?:Differences And Boundaries Among Rvers, Gloria Anne Mattingly

Theses and Dissertations

The number of leisure and working RVers roaming America?s highways, now conservatively estimated at over eight million, continues to increase (Curtin 2001; Sommer 2003). In spite of their growing presence and unique lifestyle, these populations remain sociologically understudied. This exploratory case study of two distinctly different RV parks is a small but significant step toward filling that research gap. At both RV parks I found a diverse population of individualists who value self-contained travel, freedom, relaxation, and sociality. In spite of sharing a collective, subcultural lifestyle, they differed along multiple axes. Marked differences separate RVers into three broad groups (full-timers, …
