Polyaminocarboxylic Acids As Potential Candidates For Trivalent Actinide/Lanthanide Separations, Daniel Stephen Kissel

Dissertations

Nuclear energy, which has historically been considered an alternative energy solution in the United States, is regaining support as an efficient means of energy production. The viability of nuclear energy for the future, however, will remain suspect until issues involving the waste created are fully addressed in the next generation of advanced nuclear fuel cycles. The TALSPEAK process, developed at Oak Ridge National Laboratory, is a classic solvent extraction technique that employs a series of analytical separations in an effort to remove radioactive contaminants from spent nuclear fuel (SNF) and recover uranium in high purity. This separation utilizes a polyaminocarboxylic …

A Study On The Role Of Physical Models In The Mitigation Of Design Fixation, Vimal Viswanathan, Olufunmilola Atilola, Nicole Esposito, Julie Linsey

Faculty Publications, Mechanical Engineering

Designers implement a variety of models and representations during the design process, yet little is known about the cognitive impacts of various representations. This study focuses on how physical models can assist novices in mitigating design fixation on undesirable features. During idea generation, designers tend to fixate on examples they encounter or on their own initial ideas. The first hypothesis states that designers tend to duplicate features of provided examples. The second hypothesis states that this fixation can be mitigated with appropriate warnings. The last hypothesis is that building and testing physical models can help designers in mitigating fixation. To …

Faculty Publications, Meteorology and Climate Science

During a prescribed fire experiment, CO2 and particle number concentrations, light scattering and absorption coefficients were measured from a Cessna 172 airplane. Peak number concentrations were (3 ± 1) x 106 cm–3 and they decreased faster than what can be explained by coagulation alone. The single-scattering albedo of particles grew from the values of 0.4 ± 0.1 closest to the emissions to the values of 0.8 ± 0.1 at the distance of 400 m from the emissions. The mean Ângström exponent of absorption, 1.70 ± 0.24, is in line with the published spectral absorption values of wood-smoke aerosol. The estimated …

Relating Preschool Class Size To Classroom Life And Student Achievement, Jessica Francis

Dissertations

There is an ongoing debate regarding the importance of smaller classes in elementary school, and a lack of solid research to support class size policies in preschool. State spending on preschool has nearly doubled in the last five years and currently more than 80 percent of American 4-year olds go to some kind of preschool. Increasing enrollments in preschool coupled with the high costs of reducing the size of classes creates the need to decide how many children should be placed in a preschool classroom.

The majority of states require that programs implement class sizes of 20 and teacher-child ratios …

Fitting Things Together: A Grounded Theory Study Of Clinical Judgment In Nursing, Mary Elizabeth Wilber

Dissertations

Safe and appropriate patient care hinges on the nurse's skill in assessment and interpretation of data to support accurate clinical judgments; however, a review of nursing literature reveals the lack of an empirically derived theory of clinical judgment or methods to teach the skill. Progress has been limited because of the difficulties inherent in measuring cognitive work in complex practice environments, as well as the tendency of nursing authors and researchers to substitute a wide variety of terms for clinical judgment. Knowledge development in any discipline is hampered when terms are not clearly defined and the distinction between related concepts …

Conformal Gravity Holography In Four Dimensions, Daniel Grumiller, Maria Irakleidou, Iva Lovrekovic,, Robert Mcnees

Physics: Faculty Publications and Other Works

We formulate four-dimensional conformal gravity with (anti–)de Sitter boundary conditions that are weaker than Starobinsky boundary conditions, allowing for an asymptotically subleading Rindler term concurrent with a recent model for gravity at large distances. We prove the consistency of the variational principle and derive the holographic response functions. One of them is the conformal gravity version of the Brown–York stress tensor, the other is a “partially massless response”. The on shell action and response functions are finite and do not require holographic renormalization. Finally, we discuss phenomenologically interesting examples, including the most general spherically symmetric solutions and rotating black hole …

Fluctuation-Dissipation Theorem In Isolated Quantum Systems Out Of Equilibrium, Ehsan Khatami, Guido Pupillo, Mark Srednicki, Marcos Rigol

Faculty Publications

We study the validity of the fluctuation-dissipation theorem for an isolated quantum system of harmonically trapped dipolar molecules taken out of equilibrium by means of a quench, a sudden change in the Hamiltonian parameters. We find that the integrability of the system plays a crucial role in the validity of the fluctuation-dissipation theorem. Namely, the system thermalizes according to the eigenstate thermalization hypothesis and the theorem holds if the system is nonintegrable after the quench. However, it fails if the system is integrable, unless the initial state is an eigenstate of a nonintegrable Hamiltonian, in which case the system still …

Educating Students Who Do Not Speak The Societal Language: The Social Construction Of Language-Learner Categories, Guadalupe Valdés, Luis E. Poza, Maneka Deanna Brooks

Faculty Publications

On 21 September 2012, California Assembly Bill 2193 was approved by Governor Jerry Brown. The bill added sections to California’s Education Code defining the terms long-term English learner and English learner at risk of becoming a long-term English learner. It mandated that the Department of Education collect data on the number of students corresponding to both new categories and report those data to school districts. This specific example of the construction of categories and labels matters because it is a clear example of how coexisting discourses and language ideologies provide a set of cultural rules, conditions, practices, and power …

“Time For Some Traffic Problems”: Enhancing E-Discovery And Big Data Processing Tools With Linguistic Methods For Deception Detection, Erin S. Crabb

Journal of Digital Forensics, Security and Law

Linguistic deception theory provides methods to discover potentially deceptive texts to make them accessible to clerical review. This paper proposes the integration of these linguistic methods with traditional e-discovery techniques to identify deceptive texts within a given author’s larger body of written work, such as their sent email box. First, a set of linguistic features associated with deception are identified and a prototype classifier is constructed to analyze texts and describe the features’ distributions, while avoiding topic-specific features to improve recall of relevant documents. The tool is then applied to a portion of the Enron Email Dataset to illustrate how …

Accurate Modeling Of The Siemens S7 Scada Protocol For Intrusion Detection And Digital Forensics, Amit Kleinmann, Avishai Wool

Journal of Digital Forensics, Security and Law

The Siemens S7 protocol is commonly used in SCADA systems for communications between a Human Machine Interface (HMI) and the Programmable Logic Controllers (PLCs). This paper presents a model-based Intrusion Detection Systems (IDS) designed for S7 networks. The approach is based on the key observation that S7 traffic to and from a specific PLC is highly periodic; as a result, each HMI-PLC channel can be modeled using its own unique Deterministic Finite Automaton (DFA). The resulting DFA-based IDS is very sensitive and is able to flag anomalies such as a message appearing out of its position in the normal sequence …

Personal Denial Of Service (Pdos) Attacks: A Discussion And Exploration Of A New Category Of Cyber Crime, Michael R. Bartolacci, Larry J. Leblanc, Ashley Podhradsky

Journal of Digital Forensics, Security and Law

The growth of the Internet has created a corresponding growth in Internet-based crimes and online misbehavior, particularly among younger computer-savvy people. Younger generations have grown up in a world where internet access, social networking, e-commerce and smartphones are commonplace. Given this fact, they have learned how to use, and how to abuse, technology. This leads us to define a new category of cybercrime called a Personal Denial of Service attack (PDOS). A PDOS is a cyber-crime in which an individual deliberately prevents the access of another individual or small group to online services such as email or banking. Due to …

File Detection On Network Traffic Using Approximate Matching, Frank Breitinger, Ibrahim Baggili

Journal of Digital Forensics, Security and Law

In recent years, Internet technologies changed enormously and allow faster Internet connections, higher data rates and mobile usage. Hence, it is possible to send huge amounts of data / files easily which is often used by insiders or attackers to steal intellectual property. As a consequence, data leakage prevention systems (DLPS) have been developed which analyze network traffic and alert in case of a data leak. Although the overall concepts of the detection techniques are known, the systems are mostly closed and commercial. Within this paper we present a new technique for network traffic analysis based on approximate matching (a.k.a …

Relating Admissibility Standards For Digital Evidence To Attack Scenario Reconstruction, Changwei Liu, Anoop Singhal, Duminda Wijesekera

Journal of Digital Forensics, Security and Law

Attackers tend to use complex techniques such as combining multi-step, multi-stage attack with anti-forensic tools to make it difficult to find incriminating evidence and reconstruct attack scenarios that can stand up to the expected level of evidence admissibility in a court of law. As a solution, we propose to integrate the legal aspects of evidence correlation into a Prolog based reasoner to address the admissibility requirements by creating most probable attack scenarios that satisfy admissibility standards for substantiating evidence. Using a prototype implementation, we show how evidence extracted by using forensic tools can be integrated with legal reasoning to reconstruct …

Audit: Automated Disk Investigation Toolkit, Umit Karabiyik, Sudhir Aggarwal

Journal of Digital Forensics, Security and Law

Software tools designed for disk analysis play a critical role today in forensics investigations. However, these digital forensics tools are often difficult to use, usually task specific, and generally require professionally trained users with IT backgrounds. The relevant tools are also often open source requiring additional technical knowledge and proper configuration. This makes it difficult for investigators without some computer science background to easily conduct the needed disk analysis. In this paper, we present AUDIT, a novel automated disk investigation toolkit that supports investigations conducted by non-expert (in IT and disk technology) and expert investigators. Our proof of concept design …

Evidentiary Power And Propriety Of Digital Identifiers And The Impact On Privacy Rights In The United States, Michael Losavio, Deborah Keeling

Journal of Digital Forensics, Security and Law

Media and network systems capture and store data about electronic activity in new, sometimes unprecedented ways; computational systems make for new means of analysis and knowledge development. These new forms offer new, powerful tactical tools for investigations of electronic malfeasance under traditional legal regulation of state power, particular that of Fourth Amendment limitations on police searches and seizures under the U.S. Constitution. But autonomy, identity and authenticity concerns with electronic data raise issues of public policy, privacy and proper police oversight of civil society. We examine those issues and their implications for digital and computational forensics
