A Domain Specific Language for Digital Forensics and Incident Response Analysis
Get PDFOne of the longstanding conceptual problems in digital forensics is the dichotomy between the need for verifiable and reproducible forensic investigations, and the lack of practical mechanisms to accomplish them. With nearly four decades of professional digital forensic practice, investigator notes are still the primary source of reproducibility information, and much of it is tied to the functions of specific, often proprietary, tools.
The lack of a formal means of specification for digital forensic operations results in three major problems. Specifically, there is a critical lack of:
a) standardized and automated means to scientifically verify accuracy of digital forensic tools;
b) methods to reliably reproduce forensic computations (their results); and
c) framework for inter-operability among forensic tools.
Additionally, there is no standardized means for communicating software requirements between users, researchers and developers, resulting in a mismatch in expectations. Combined with the exponential growth in data volume and complexity of applications and systems to be investigated, all of these concerns result in major case backlogs and inherently reduce the reliability of the digital forensic analyses.
This work proposes a new approach to the specification of forensic computations, such that the above concerns can be addressed on a scientific basis with a new domain specific language (DSL) called nugget. DSLs are specialized languages that aim to address the concerns of particular domains by providing practical abstractions. Successful DSLs, such as SQL, can transform an application domain by providing a standardized way for users to communicate what they need without specifying how the computation should be performed.
This is the first effort to build a DSL for (digital) forensic computations with the following research goals:
1) provide an intuitive formal specification language that covers core types of forensic computations and common data types;
2) provide a mechanism to extend the language that can incorporate arbitrary computations;
3) provide a prototype execution environment that allows the fully automatic execution of the computation;
4) provide a complete, formal, and auditable log of computations that can be used to reproduce an investigation;
5) demonstrate cloud-ready processing that can match the growth in data volumes and complexity
The Color of Invisibility
Get PDFThis thesis is an analysis of Ralph Ellison’s use of color terminology in his novel, Invisible Man. By taking an in depth look at the circumstances in which Ellison uses specific color terms, the reader can ascertain the author’s thoughts on various historical events, as well as the differences between characters in the novel such as Ras, Dr. Bledsoe, and Rinehart
Past the Darkness
Get PDFThis paper will discuss the making of my thesis film, Past the Darkness. I will describe the entire process including story conception, film production, and post-production stages. I will also evaluate the merits, flaws, and outcome of this project
Seamless Lidar Surveys Reveal Rates and Patterns of Subsidence in the Mississippi River Delta
Get PDFLight Detection and Ranging (Lidar) data are used to report the temporal and spatial patterns of subsidence as well as the potential contributors to subsidence within the Barataria and Terrebonne Bays. In recent decades, subsidence in southeast Louisiana has become a topic of substantial and growing concern to the scientific community, the local residents, and all those invested in the region. Lidar data were acquired from the United States Geological Survey (USGS) and the LSU Center for Geoinformatics. The data has been manipulated to map the differenced Lidar, complete an instantaneous slope analysis, and determine the thickness of the Holocene sediments. The goal was to gain a more comprehensive understanding of the subsidence patterns and the dynamic processes driving subsidence within the study area. These efforts provide a better ability to plan for the future of the Louisiana working coast and mitigate against relative sea level rise and coastal land loss
Nurse Anesthesia Program Administrator\u27s Decision-Making in Determining Interventions for a Student Exhibiting Unsatisfactory Clinical Performance
Get PDFThe purpose of this grounded theory study is to define the process that nurse anesthesia program administrators use to determine if a student nurse anesthetist’s unsatisfactory clinical performance warrants intervention by the program. There is little room for error in anesthesia practice as mishaps typically result in significant injury and death. Students who exhibit unsatisfactory clinical performance may pose an immediate risk to patient safety as well as a future risk if allowed to progress in the program. The lack of guidance in the form of clearly articulated expectations and processes contribute to the emotional strain nurse anesthesia faculty and administrators experience when observing unsatisfactory clinical performance. From the data collected in the interviews with ten nurse anesthesia program administrators, a five-phase decision-making model entitled the Nurse Anesthesia Program Administrator Decision Making Model was developed. The five phases of the model include: receiving the feedback, validating the concern, assessing accountability and planning for remediation, removing the student from clinical training and moving to dismissal, and notifying the student of the decision. The guiding principle of this model is the importance of following institutional and program policies throughout the process. This study is intended to provide guidance to nurse anesthesia program administrators who are faced with a student demonstrating unsatisfactory clinical performance regarding what behaviors may require an intervention by the program
“An’ No Place to Lead ‘Em”: The Grapes of Wrath and the Breakdown of Myth
Get PDFIn spite of its common designation as an outmoded classic of sentimental middlebrow literature, John Steinbeck’s The Grapes of Wrath remains relevant as a milestone in an extended liminal stage between the failing cultural myths of the past and the founding of newly relevant shared stories. This stage begins with the Enlightenment and continues to present-day conflicts over identity, labor, migrants, notions of truth itself, the function and responsibilities of government, and our shared ecological destiny. Arriving near the end of the Depression and its concurrent economic and environmental disasters, The Grapes of Wrath reflects a particularly chaotic stage in mythological disintegration and regeneration. While critics routinely note the structure of myths within the narrative, they too often fail to note the ways said structures fail, providing for the oppressive tone of the narrative, which ironically leaves space for the rise of new myths
Total Fume Emissions and Emission Factors Applicable to Gas Metal Arc Welding
Get PDFWelding is a common industrial practice that has the potential to emit air pollutants. Emission factors are useful indicators to help in the understanding of the extent of pollution from a process and managing them to reduce or minimize health impacts. The objective of this thesis is to determine emission factors applicable to the gas metal arc welding (GMAW), under varying current and voltage conditions. The most used base metals and an electrode for the shipbuilding industry were considered. A weld fume chamber was used to achieve the project goals along with standard sampling and analytical procedures. Three test runs were performed for each sampling scenario to ensure repeatability. The EPA EF average for MS experiments with the ER70S-6 electrode is 5.2 g/kg, and for SS experiments with the ER316L-Si electrode is 3.2 g/kg, while the average results for this study were 6.81 g/kg and 3.28 g/kg respectively
