In most of the work using event-related potentials (ERPs), researchers presume the function of specific components based on the careful manipulation of experimental factors, but rarely report direct evidence supporting a relationship between the neural signal and other outcomes. Perhaps most troubling is the lack of evidence that ERPs correlate with related behavioral outcomes which should result, at least in part, from the neural processes that ERPs capture. One such example is the NoGo-N2 component, an ERP component elicited in Go/NoGo paradigms. There are two primary theories regarding the functional significance of this component in this context: that the signal represents response inhibition and that the component reflects conflict. In this paper, a trial-level method of analysis for the relationship between ERP component potentials and downstream behavioral outcomes (in this case, response accuracy) using a multi-level modeling framework is proposed to provide discriminatory evidence for one of these theories. Following a description of the research on the NoGo-N2, preliminary data supporting the conflict monitoring theory are presented, noting important limitations. Next, an EEG simulation study is presented in which NoGo-N2 data are generated with a known relationship to fabricated reaction time data, showing that, with added levels of complexity and noise within the data, the MLM approach is consistently successful at extracting the known relationships that occur in real NoGo-N2 data. Next, using independent components analysis (ICA) to extract spatiotemporal components that best represent the signal of interest, a well-powered analysis of the relationship between the NoGo-N2 and response accuracy is used to provide strong discriminatory evidence for the conflict monitoring theory of the NoGo-N2. Finally, implications for the NoGo-N2, as well as all ERP components, are discussed with a focus on how this approach can and should be used. the paper concludes with potential expansions of this approach to areas beyond identifying the function of ERP components.

Enterprise Resource Planning systems (ERP systems) are business systems that combine data from across a company into one streamlined database (Bradford, 2015). ERP systems are intended to make people’s lives easier and more convenient in the workplace, but they can be cumbersome to deal with for employees, even those with experience. This thesis aims to understand and offer solutions to three key problems in using and implementing ERP systems, incorrect implementation, a lack of proper resources, and low motivation. It offers a framework of three solutions that are easy to implement and maintain. The first is to offer proper change management because “Change management is the body of knowledge that addresses change within the context of an organization,” (Bradford, 2015). The second is to understand employees as individuals with unique backgrounds and learning styles. Finally, the third is to implement an easily searchable database of common questions and issues that arise when using the ERP system, but for each individual department. These are then applied to the transition of Blackboard to Canvas at Arizona State University with a short informal survey that was sent out to faculty members. Lastly, this thesis describes how to motivate employees to want to use these solutions and changes.

Unmanned aerial vehicles have received increased attention in the last decade due to their versatility, as well as the availability of inexpensive sensors (e.g. GPS, IMU) for their navigation and control. Multirotor vehicles, specifically quadrotors, have formed a fast growing field in robotics, with the range of applications spanning from surveil- lance and reconnaissance to agriculture and large area mapping. Although in most applications single quadrotors are used, there is an increasing interest in architectures controlling multiple quadrotors executing a collaborative task. This thesis introduces a new concept of control involving more than one quadrotors, according to which two quadrotors can be physically coupled in mid-flight. This concept equips the quadro- tors with new capabilities, e.g. increased payload or pursuit and capturing of other quadrotors. A comprehensive simulation of the approach is built to simulate coupled quadrotors. The dynamics and modeling of the coupled system is presented together with a discussion regarding the coupling mechanism, impact modeling and additional considerations that have been investigated. Simulation results are presented for cases of static coupling as well as enemy quadrotor pursuit and capture, together with an analysis of control methodology and gain tuning. Practical implementations are introduced as results show the feasibility of this design.

There has been a vast increase in applications of Unmanned Aerial Vehicles (UAVs) in civilian domains. To operate in the civilian airspace, a UAV must be able to sense and avoid both static and moving obstacles for flight safety. While indoor and low-altitude environments are mainly occupied by static obstacles, risks in space of higher altitude primarily come from moving obstacles such as other aircraft or flying vehicles in the airspace. Therefore, the ability to avoid moving obstacles becomes a necessity

for Unmanned Aerial Vehicles.

Towards enabling a UAV to autonomously sense and avoid moving obstacles, this thesis makes the following contributions. Initially, an image-based reactive motion planner is developed for a quadrotor to avoid a fast approaching obstacle. Furthermore, A Dubin’s curve based geometry method is developed as a global path planner for a fixed-wing UAV to avoid collisions with aircraft. The image-based method is unable to produce an optimal path and the geometry method uses a simplified UAV model. To compensate

these two disadvantages, a series of algorithms built upon the Closed-Loop Rapid Exploratory Random Tree are developed as global path planners to generate collision avoidance paths in real time. The algorithms are validated in Software-In-the-Loop (SITL) and Hardware-In-the-Loop (HIL) simulations using a fixed-wing UAV model and in real flight experiments using quadrotors. It is observed that the algorithm enables a UAV to avoid moving obstacles approaching to it with different directions and speeds.

The locus coeruleus-norepinephrine system (LC-NE) has been argued to play a vital role in task engagement and attention control by the adaptive gain theory (Aston-Jones & Cohen, 2005). One of the central claims of this theory is that tonic LC activity exhibits a quadratic relationship with task performance. Pupil dynamics have been correlated to LC-NE activity via primate intracranial recordings in ways that provide evidence for the adaptive gain theory. Due to the small size and location of the LC, less is known about LC functioning in humans, leading to a desire to find valid, noninvasive psychophysiological proxies to study this structure. In this paper we performed a replication of Murphy, Robertson, Balsters, & O’Connell (2011) to gather evidence on whether pupil fluctuations and the P3 event-related potential are viable markers for measuring tonic and phasic LC-NE activity in humans. A sample of 33 subjects from the Arizona State University human subjects pool provided usable electroencephalogram and pupillometry data collected during an auditory oddball task. Our analyses largely correspond with those found in Murphy et al. (2011) showing some evidence that pupillometry and P3 can be utilized when studying the LC. Moving forward we will reproduce the full set of analyses from Murphy et al. (2011) with our dataset.

In the end, an increase in repurchases of company stock will also influence the rate of dividends to increase. This means, an investor should not necessarily worry about the dividends they receive, but rather to see if the company is making profit at a consistent rate and reinvesting into value-added activities. Through the major pillars of finance, technology, legal, and human resources, the budget for reinvestment can be optimized by investing into these respective categories with percentages that are mindful of the specific companies needs and functions. Any firm that chooses to ensure proven methods of growth will enact a combination of these four verticals. A larger emphasis on finance will branch out efficiency in the entire organization, as finance control everything from the toilet paper to the acquisitions the company is making. The more technology is used to reduce redundancy and inefficient or costly operations, the more capability the organization will have. IT, however, comes with its technical challenges; having a team on-hand or even outsourced, to solve the critical problems to help the business continue operation. Over-reliance into technology can be detrimental to a business as well if clear processes are not set about straight to counteract problems the business will face like IT ticketing systems or recovery and continuity support. Therefore, technology will require a larger chunk of attention as well.

The upcoming legal and HR investments a company will make will depend upon its current position and thus the restructuring will differ for every firm. Each company has its own flavour and style of work. In that regard, the required legal counsel will vary; different problems will require different solutions for risk control and management, which are often professionally advised by intelligent corporate counsel. This ability to hire efficient legal counsel would not arise in the first place if a firm were to give out dividends; the leftover profit would have gone towards the shareholders and not back into growing the equity of the business. Lastly, nothing is possible without the contribution of people, and their efforts. A quality that long-lasting, successful businesses have, is they are investing in their people and development. Paying salaries, insurances, bonuses, all requires extra capital that is needed to be set aside in order to grow human capital. Good people, better people. There are qualities for each role that need to be defined and a process for attracting talent needs to be invested in. This process can also include outsourcing to an external firm who specializes in these strategies. By retaining profits internally, the company is able to stretch its legs to have further reach upon the market they work in. Financially and statistically, dividends are likely to grow as well with the increase in equity due to the increase in security an investor feels with more cash reserve and liquidity within the company.

All in all, a company should not be pressured into giving out periodic payments in predetermined timeframes, in other words a dividend, to investors even when they are insisting. Rather, pitch and prove, a new method for reinvestment within the company that will raise the value of the company, through proven methods like the value chain model, to increase the equity in the company. By expanding the scope and capability, the company is allowing for a larger target market which will reap more benefits; none of it would be possible if it had continued to give out large percentages of capital to investors as dividends. Companies, and investors, should not be worried about dividends at all as a matter of fact; an increase in stock buyback, in other words reinvesting into the company, will increase the rate of dividends anyway, due to increased confidence and capital within the company.
