An area of study that has received much attention over the past few decades is simulations involving threat assessment in military scenarios. Recently, much research has emerged concerning the recognition of troop movements and formations in non-combat simulations. Additionally, there have been efforts towards the detection and assessment of various types of malicious intentions.

Show moreAn area of study that has received much attention over the past few decades is simulations involving threat assessment in military scenarios. Recently, much research has emerged concerning the recognition of troop movements and formations in non-combat simulations. Additionally, there have been efforts towards the detection and assessment of various types of malicious intentions. One such work by Akridge addressed the issue of Strategic Intention Recognition, but fell short in the detection of tactics that it could not detect without somehow manipulating the environment. Therefore, the aim of this thesis is to address the problem of recognizing an opponent's intent in a strategic environment where the system can think ahead in time to see the agent's plan. To approach the problem, a structured form of knowledge called Template-Based Interpretation is borrowed from the work of others and enhanced to reason in a temporally dynamic simulation.

- FAMTILE: AN ALGORITHM FOR LEARNING HIGH-LEVEL TACTICAL BEHAVIOR FROM OBSERVATION.

Stensrud, Brian, Gonzalez, Avelino, University of Central Florida
- Abstract / Description

This research focuses on the learning of a class of behaviors defined as high-level behaviors. High-level behaviors are defined here as behaviors that can be executed using a sequence of identifiable behaviors. Represented by low-level contexts, these behaviors are known a priori to learning and can be modeled separately by a knowledge engineer. The learning task, which is achieved by observing an expert within simulation, then becomes the identification and representation of the low-level...
Show moreThis research focuses on the learning of a class of behaviors defined as high-level behaviors. High-level behaviors are defined here as behaviors that can be executed using a sequence of identifiable behaviors. Represented by low-level contexts, these behaviors are known a priori to learning and can be modeled separately by a knowledge engineer. The learning task, which is achieved by observing an expert within simulation, then becomes the identification and representation of the low-level context sequence executed by the expert. To learn this sequence, this research proposes FAMTILE - the Fuzzy ARTMAP / Template-Based Interpretation Learning Engine. This algorithm attempts to achieve this learning task by constructing rules that govern the low-level context transitions made by the expert. By combining these rules with models for these low-level context behaviors, it is hypothesized that an intelligent model for the expert can be created that can adequately model his behavior. To evaluate FAMTILE, four testing scenarios were developed that attempt to achieve three distinct evaluation goals: assessing the learning capabilities of Fuzzy ARTMAP, evaluating the ability of FAMTILE to correctly predict expert actions and context choices given an observation, and creating a model of the expert's behavior that can perform the high-level task at a comparable level of proficiency.

Cardiovascular diseases cause 17 million deaths annually, which is estimated to increase to 23 million deaths by the year 2030. One of the major risk factors for the pathogenesis of cardiovascular diseases is increased secretion of very-low density lipoproteins (VLDL) by the liver; however, reduced VLDL-secretion causes fatty liver disease.

Show moreCardiovascular diseases cause 17 million deaths annually, which is estimated to increase to 23 million deaths by the year 2030. One of the major risk factors for the pathogenesis of cardiovascular diseases is increased secretion of very-low density lipoproteins (VLDL) by the liver; however, reduced VLDL-secretion causes fatty liver disease. Synthesis and secretion of VLDL by the liver plays an important role in maintaining overall lipoprotein homeostasis. Assembly of VLDL occurs along with the expression of apolipoproteinB-100 (apoB100) and its lipidation at the endoplasmic reticulum (ER) level. Once formed in the ER lumen, the nascent VLDL is transported to the Golgi for its maturation. In the Golgi compartment, the nascent VLDL acquires apolipoproteinAI (apoAI), more triglycerides, and its apoB100 undergoes phosphorylation and glycosylation. These modifications are necessary for VLDL-exit from the trans-Golgi network (TGN) and this step is mediated by post-Golgi VLDL transport vesicle (PG-VTV). The transport of mature VLDL from the TGN to the plasma membrane (PM) is required for its secretion by the liver but remains to be studied. Our group has shown that the nascent VLDL particles do not contain apoAI, however, VLDL acquires apoAI in the cis-Golgi compartment. Interestingly, apoAI comes off the VLDL as soon as VLDL is secreted into the blood. We hypothesised that apoAI plays an important role in post-TGN VLDL trafficking and thus controls VLDL secretion by the liver. To determine the role of apoAI in the formation of PG-VTV and VLDL secretion, we knocked down apoAI in the hepatocytes using apoAI specific siRNA. The deficiency of apoAI did not have any effect on the expression of apoB100 and other apolipoprotein synthesis that are involved in VLDL synthesis; however, VLDL secretion was significantly reduced. Next, we overexpressed apoAI using plasmid with apoAI gene sequence and checked for the effects in VLDL secretion from the hepatocytes. We observed a significant increase in VLDL secretion from apoAI-overexpressing hepatocytes which is consistent with knockdown results. To determine the role of apoAI in post-TGN trafficking of the mature VLDLs, we isolated sub-cellular organelles from apoAI knockout (apoAI KO) and control mice. Subsequently, we performed in vitro PG-VTV budding assays to assess the effect of apoAI silencing on PG-VTV formation from the TGN. Our results strongly suggest that the deficiency of apoAI increases PG-VTV formation (i.e. TGN-exit of mature VLDL) but significantly reduces VLDL-triglyceride secretion from the hepatocytes. We conclude that apoAI controls VLDL secretion by the liver by regulating post-TGN trafficking of mature VLDL.

Show moreRobots have been a part of the imagination of Western culture for centuries. The possibility for automation and artificial life has inspired the curiosity of thinkers like Leonardo Da Vinci who once designed a mechanical knight. It wasn't until the 19th century that automated machinery has become realized. The confrontation between human and automation has inspired a fear, referred to as (")technopanic("), that has been exacerbated in tandem with the evolution of technology. This thesis seeks to discover the historical precedence for these fears. I explore three modes of knowledge (Philosophy, Economics, and Film Theory) to examine the agendas behind the messages on the topic of Artificial Life, specifically Robots. I then advocate for an alternative philosophy called Post-Humanism. I argue that what is needed to alleviate the fears and anxieties of Western culture is a shift in how humanity views itself and its relation to the natural world. By structuring my thesis in this way, I identify the roots of Western humanity's anthropocentric ontology first, explore the economic implications of automation second, analyze the cultural anticipations of artificial life in Western media third, and finally offer an alternative attitude and ethic as a way out of the pre-established judgments that do little to protect Western culture from E.A.I.
