Algorithms And Data Structures For Efficient Timing Analysis Of Asynchronous Real-Time Systems, Yingying Zhang

USF Tampa Graduate Theses and Dissertations

This thesis presents a framework to verify asynchronous real-time systems based on model checking. These systems are modeled by using a common modeling formalism named Labeled Petri-nets(LPNs).

In order to verify the real-time systems algorithmically, the zone-based timing analysis method is used for LPNs. It searches the state space with timing information (represented by zones). When there is a high degree of concurrency in the model, firing concurrent enabled transitions in different order may result in different zones, and these zones may be combined without affecting the verification result. Since the zone-based method could not deal with this problem efficiently, …

The Impact Of Hyperfemininity On Explicit And Implicit Blame Assignment And Police Reporting Of Alcohol Facilitated Rape In A Sample Of College Women, Sarah Ehlke

USF Tampa Graduate Theses and Dissertations

Rape remains a significant problem in the U.S., with the majority of victims reporting a drug-or-alcohol facilitated rape (DAFR) or incapacitated rape (IR). Many DAFR/IR victims do not acknowledge the incident as a rape, and are therefore are the least likely to report or disclose the assault. Rape scripts theory is one theory that could be used to explain why DAFR/IR victims are more likely than other victims to not acknowledge the incident. In addition, individuals are more likely to blame the victim of a DAFR/IR rape. Furthermore, DAFR/IR victims experience more self-blame for the incident. Taken together, when alcohol …

Defining And Preventing Code-Injection Attacks, Donald Ray

USF Tampa Graduate Theses and Dissertations

This thesis shows that existing definitions of code-injection attacks (e.g., SQL-injection attacks) are flawed. The flaws make it possible for attackers to circumvent existing mechanisms, by supplying code-injecting inputs that are not recognized as such. The flaws also make it possible for benign inputs to be treated as attacks. After describing these flaws in conventional definitions of code-injection attacks, this thesis proposes a new definition, which is based on whether the symbols input to an application get used as (normal-form) values in the application's output. Because values are already fully evaluated, they cannot be considered ``code'' when injected. This simple …

Evaluation Of Using An Interrupted Behavior Chain Procedure To Teach Mands To Children With Autism, Blair Nichole Jacobsen

USF Tampa Graduate Theses and Dissertations

Abstract

Interrupted behavior chain procedures have been shown to be an effective way to teach individuals with intellectual disabilities and autism to mand for missing objects and information concerning missing objects. Research has shown that an interrupted behavior chain procedure is more effective than traditional mand teach trials, which occur at the onset of a behavior chain or in a massed trial format. However, there is a lack of research evaluating the use of interrupted behavior chain procedures to teach vocal mands for missing items and the possible generalization effects thereof. This study evaluated the acquisition of vocal mands for …

Full 3d Reconstruction From Multiple Rgb-D Cameras, Owen Watson

USF Tampa Graduate Theses and Dissertations

This thesis describes a novel procedure for achieving full 3D reconstruction from multiple RGB-D cameras configured such that the amount of overlap between views is low. Overlap is used to describe the portion of a scene that is common in a pair of views, and is considered low when at most 50% of the scene is common. Compatible systems are configured such that interpreting cameras as nodes and overlap as edges, a connected undirected graph can be constructed. The fundamental goal of the proposed procedure is to calibrate a given system of cameras. Calibration is the process of finding the …

Robotic Swarming Without Inter-Agent Communication, Daniel Jonathan Standish

USF Tampa Graduate Theses and Dissertations

Many physical and algorithmic swarms utilize inter-agent communication to achieve advanced swarming behaviors. These swarms are inspired by biological swarms that can be seen throughout nature and include bee swarms, ant colonies, fish schools, and bird flocks. These biological swarms do not utilize inter-agent communication like their physical and algorithmic counterparts. Instead, organisms in nature rely on a local awareness of other swarm members that facilitates proper swarm motion and behavior. This research aims to pursue an effective swarm algorithm using only line-of-sight proximity information and no inter-agent communication. It is expected that the swarm performance will be lower than …

A Multi-Parameter Functional Side Channel Analysis Method For Hardware Trojan Detection In Untrusted Fpga Bitstreams, Christopher William Bell

Comparison Of Acquisition Rates And Child Preference For Varying Amounts Of Teacher Directedness When Teaching Intraverbals, Victoria Lynn Smith

USF Tampa Graduate Theses and Dissertations

The intraverbal is argued to be the most socially significant verbal operant and yet it is the least studied. Heal and Hanley (2011) suggest that different teaching strategies will lead to different rates of acquisition and child-preference with the tacting operant. This study continued this research into the realm of intraverbals, with focus on whether the embedded teaching strategy could be punishing on play or engaging in learning opportunities. The teaching strategies of discovery teaching, embedded prompting, and direct teaching were compared to see which strategy correlated with higher rates of acquisition and higher child preference. The study utilized a …

Assessing The Relationship Between Hotspots Of Lead And Hotspots Of Crime, Kimberly L. Barrett

USF Tampa Graduate Theses and Dissertations

Numerous medical and environmental toxicology studies have established a link between lead (Pb) exposure, crime, and delinquency. In human environments, lead pollution- like crime- is unequally distributed, creating lead hot spots. In spite of this, studies of crime hotspots have routinely focused on traditional sociological predictors of crime, leaving environmental predictors of crime like lead and other neurotoxins relatively unaddressed. This study attends to this gap in the literature by asking a very straightforward research question: Is there a relationship between hotspots of lead and hotspots of crime? Furthermore, what is the nature and extent of this relationship? Lastly, is …

Effects Of Response Cards On The Disruptive Behavior Of Students, Leslie S. Singer

USF Tampa Graduate Theses and Dissertations

Abstract

This study examined the effects of response cards (RC) on student disruptive behavior, responding, and accuracy of responding during whole-class guided-reading instruction in a first-grade classroom. The authors combined two baseline conditions with an alternating treatments design and then replicated the effects across four teacher-nominated students. The first baseline condition was the teacher's typical instruction format, where one student who raised his/her hand was called upon to respond to the teacher's question. The second baseline condition (BL') was the same as the first baseline with an additional control for the number of teacher-delivered questions to the class per session. …

A Comparison Of A Matrix Programming And Standard Discrete Trial Training Format To Teach Two-Component Tacts, Emily Braff

USF Tampa Graduate Theses and Dissertations

Teaching using matrix programming has been shown to result in recombinative generalization. However, this procedure has not been compared to more standard discrete trial training formats such as DTT. This study compared acquisition and recombinative generalization of two-component tacts using each procedure. Matrix training was found to be more efficient than the DTT format. Half the amount of teaching was required to teach roughly the same number of targets using matrix training as compared to DTT.

The Effects Of Video Self-Evaluation On Skill Acquisition With Yoga Postures, Holly Elizabeth Downs

USF Tampa Graduate Theses and Dissertations

This study evaluated the use of video self-evaluation and video feedback procedures to enhance the accuracy of yoga poses. In the self-evaluation intervention participants watched their behaviors via video and scored task analyses for feedback for each pose.

The interventions were assessed in a multiple baseline across behaviors design. Results showed that both video self-evaluation increased the accuracy of all poses and video feedback further increased the accuracy on one pose for one participant

Evaluating The Effectiveness Of A Tablet Application To Increase Eye Contact In Children Diagnosed With Autism, Tricia Jeffries

USF Tampa Graduate Theses and Dissertations

Studies have shown that increasing eye contact can be accomplished by using reinforcement, prompting, shaping, functional movement training, punishment, and self-monitoring. However, there is a lack of research that evaluates the use of technology as a way to increase eye contact. This study tested the effectiveness of a tablet application at increasing eye contact in children diagnosed with autism. The application requires the child to look at a picture of a person's face and identify the number displayed in the person's eyes in order to receive reinforcement. Data was collected immediately after training, one hour after training, and in the …

Examining The Link Between Self-Control And Misconduct In A Multi-Agency Sample Of Police Supervisors: A Test Of Two Theories, Christopher Matthew Donner

USF Tampa Graduate Theses and Dissertations

As police personnel carry out their mandates of enforcing the law, maintaining order, and serving the public, they are entrusted to "practice what they preach." They are expected to abide by the rules, laws, and ethical principles that apply to them as they hold private citizens to account for violations of laws. When the police do not live up to this standard by committing police misconduct, it can tarnish not just the individual officer, but the department and jurisdiction as well. Police misconduct is a concern for society as police misbehavior can result in negative outcomes, such as distrust by …
