  Nonlinear MIMO Adaptive Control for Longitudinal Aerodynamics Forces and Moments of Hypersonic Aircraft Vehicle Model

  Turki Mohammed Alsuwian

  Aircraft vehicle has complex nonlinear functions which affected in design the control issues. In this paper, introduce and design accurate control of longitudinal dynamic and pitch moment. Longitudinal dynamics equations have complex parameters and this paper maintains control methods as using feedback linearization method. This method is separating longitudinal dynamics equations which causes directly to the flight path angle and aircraft speed with certain approximations of drag, lift and moment functions. Therefore, MIMO adaptive control approach is used instead of feedback linearization with first approximations of drag, lift and moments functions to achieve reasonable results of aircraft dynamics control. MIMO adaptive control technique is presented combined direct and indirect adaptive control methods because the uncertainties variables of longitudinal equations. This paper displays control design for thrust and elevator deflection as inputs of aircraft dynamic with flight path angle and aircraft speed as outputs of the system. The simulations results of feedback linearization and MIMO adaptive control is illustrated in this paper and achieved the tracking of aircraft speed and flight path angles to desired aircraft speed and desired flight path angle.

  Onboarding Career College Faculty: Helping Student Success

  Elizabeth M. Fogle-Young

  Students attending career colleges are typically at higher risk of dropping out or stopping out of school given many external factors such as working full-time or raising families. For these at-risk students, relationships with faculty and staff members on campus help create an environment that is more likely to help them succeed. In addition, Tinto (1993) described how important the instructor and classroom experience specifically are to student success and retention. As such, it is important that faculty members are prepared from the first day they enter the classroom to provide the necessary balance of support and challenge to these students. Lounder, et al. (2011) discussed recent studies suggesting that adjunct faculty in general may be less effective in the classroom. At a time when many colleges are using more adjunct faculty, finding ways to help these instructors be more prepared and effective should be of importance to all colleges and career colleges in particular. One way that career colleges can help instructors be prepared from day one is to institute more rigorous and impactful orientation or onboarding programs. The purpose of this presentation is to combine current research in faculty life with research in human resources and onboarding to suggest best practices for onboarding career college faculty.

  Optimization of Photovoltaics Recycling Network: Case Study of California

  Qi Guo

  In the United States, there is no systematic movement to set up a photovoltaics (PV) recycling infrastructure as of now. Like any other end-of-life planning, it is vital to develop and institute economically feasible and environmentally viable recycling infrastructure for the emerging PV industry in parallel with the rapid commercialization of these new technologies. PV recycling planning includes various challenging issues in temporal, spatial, and technical dimension. Various stakeholders will be involved in the recycling network and the issue of management covers diverse aspects such as the collection, distribution, inventory, and reclaiming of materials. Within such a complex recycling network, a systematic approach has to be adopted to adequately capture the dynamic interactions between stakeholders. The main objective of this study is to develop a rigorous mathematical framework, with which to analyze the economic feasibility of PV recycling systems in the United States. California is selected as the geographical location of this study because of the prevalence of PV installation as well as the strict environmental regulation in the region. There are four main steps of research performed: 1) Information about the location of all the PV installation sites in the state of California along with the location of stakeholders involved in the proposed recycling framework are gathered, 2) Geographic Information Systems (GIS) tool boxes are utilize to locate the feasible location of PV recycling centers for various scenarios, 3) total system costs and environmental emissions generated from diverse PV recycling scenarios are compared, 4) economic and environmental trade-off analysis are performed to assist optimized decision making processes. The outcome of this research will facilitate systems analyses for planning of state and national recycling programs for various kinds of PV modules. The general framework developed by the proposed research will allow an efficient decision making on the conservation of natural resources and the mitigation of environmental emission.

  “Optimization of the hydro thermal liquefaction process for increased yields, and for both energy and cost efficient production of a cleaner bio-crude suitable for refineries”

  Anirban Mandal

  Increased use and limited reserves of fossil fuels have increased interest in renewable fuels. Algae biomass has been identified as a viable renewable fuel feedstock for biofuel (green diesel / jet fuel) generation. Hydrothermal liquefaction (HTL) is a promising energy efficient technology for converting wet-algae biomass into energy dense “bio-crude” suitable for use in refineries and recycling nutrients for growing algae. The composition of the bio-crude affects the quality and the process economics involved in converting the bio-crude to commercial fuel. Both the process operating conditions and the algal HTL feedstock composition affect the bio-crude composition. Thus, the proposed effort will focus on determining the ideal HTL conditions with various algal biomass compositions.

  Perfectionism, Religious Orientation, and Self-Forgiveness: Mediating and Moderating Factors

  Nicole Marie Miller, Sarah A. Wilhoit

  The relationships between interpersonal forgiveness, perfectionism, and religious orientation have been previously studied (e.g., Ashby & Huffman, 1999; Dixon, Earl, Lutz-Zois, Goodnight, & Peatee, 2014; Meek, Albright, & McMinn, 1995; Steffen, 2013). However, the present study examines how different types of forgiveness, self-forgiveness and perceived forgiveness from God, are related to perfectionism and religious orientation. Previous research indicates that self-evaluative perfectionism, the more maladaptive type of perfectionism (Hill et al., 2004), is negatively associated with intrinsic religious orientation (Ashby & Huffman, 1999). Those with an intrinsic orientation, who profess faith as central to their identity (Allport & Ross, 1967), are more likely to self-forgive (Gordon et al., 2008). Conversely, self-evaluative perfectionism is positively associated with extrinsic orientation (Ashby & Huffman, 1999; Steffen, 2013), in which religion is practiced for social benefits. The present study used a subset of pre-collected data from a larger pool. We first hypothesized that the relationship between self-evaluative perfectionism and self-forgiveness would be mediated by religious orientation. Second, we hypothesized that the relationship between religious orientation and self-forgiveness would be moderated by perceived forgiveness from God, such that people higher in intrinsic religiosity would self-forgive to the extent that they felt forgiven by God. This was not predicted for people higher in extrinsic religiosity. Results indicated that religious orientation did not mediate the relationship between self-evaluative perfectionism and self-forgiveness. Further, perceived forgiveness from God did not moderate the relationship between religious orientation and self-forgiveness in those who were higher in intrinsic religiosity, but it did moderate a positive relationship in those who were higher in extrinsic religiosity. The findings of this study were unexpected, warranting additional research looking into factors that may make extrinsically religious people more likely to self-forgive if they are forgiven by God.

  Power Efficient Circuits for Intrusion Detection using Memristor Crossbars

  Venkataramesh Bontupalli

  Intrusion Detection System (IDS) is an intelligent specialized system designed to interpret the intrusion attempts in incoming network traffic. IDS aims at minimizing the risk of accessing the unauthorized data and potential vulnerabilities of critical systems by the examining the every packet entering into the system. Deep Packet inspection and Pattern matching are computationally intensive processes and most power hungry functionalities in network intrusion detection systems. In particular, every incoming packet is well screened by string matching with previously known malicious signatures/contents essentially known as attacks or intrusions. In particular, nearly 70 % of the execution time and power is utilized against matching the malicious contents against all the incoming packets. Indeed, the heart of every IDS is the detection process itself hence our key focus and efforts are towards developing a memristor crossbar based low power intrusion detection system that would reduce the execution time and power consumption due to its high density grid and massive parallelism. We propose a brute force string matching algorithm implementation on a low power memristor based cross bar array giving rise to detection accuracy of 100% and 0% false positive consuming 0.013mW/signature. As it turns out, memristor cross bar designed, trigger only if there is an exact match between the stored and incoming pattern extending its applications towards text processing, speech processing, computational biology, etc. besides intrusion detection.

  Public Service Motivation: Exploring Motives of the Public Sector and Identifying the Pursuit of Vocation

  Morgan Elizabeth Draves

  As a University Political Science student and Honors Program Chaminade Scholar, the themes of public service and vocation have largely influenced my academic curriculum while at the University. Public service motivation has been a thoroughly studied topic within the discipline of public administration and acts as a form of measurement in determining the motives of public servants, including but not limited to organizational structures and a variety of socialization factors. The aim of this project is to find the correlation between public service and the different levels of vocation that are perceived among individuals working in the public sector. Through a series of interviews with and surveys of public servants, a realistic perspective of public service motivation will be obtained. The key objective of this project is to study public service motivation and its components in order to characterize the various levels of vocation that exist within the public sector.

  Quantifying the Impact of Adding Renewable Energy on the Grid from Economic Point of View

  Seyed Ataollah Raziei

  Growth in renewable energy, particularly of wind power and solar photovoltaics (PV) has been rapid over the past decade, averaging 25-30% a year. There are several reasons for this growth, including recognition that mitigation of anthropogenic climate change, mainly due to emissions of carbon dioxide from fossil-fuel combustion will require a dramatic transformation in our energy system over the course of the next few decades. Renewable energy generation has several benefits not only for our generation, but for our children as well.However, the problems of adding more renewable energy, specifically from the point of view of the stability and reliability of the grids have gradually come to light. Nowadays rather than uncertainty behind the demand behavior, electricity entities have to deal with uncertainty behind the renewable energy generation. Because of this, stabilizing the electrical grids has become more complicated.Substantial research is going on in order to remedy the problems of stabilizing the grids having a notable percentage of renewable energy on the grid. One of the best offered solution is adding storage systems on the grids. However the main problem is a lack of consideration of the problem from the economic point of view.The primary aim of the proposed research is to pair the offered solutions of stabilizing the grid to the economic assessment of the grid. The main focus will be on the macro scale of the grid when distributed storage and renewable energy generation exist. Both short term and long term feedback of deploying each scenario will be considered.

  Race or Culture? African American Student Experiences at a Predominantly White Institution

  Kelley McClain

  This qualitative study explores the experiences of African American students who attend predominantly White institutions. Several factors could benefit, hinder and/or frustrate African American students who have decided to pursue and complete higher education at a predominantly White institution. However, the responsibility of administrators to assist African Americans with this transition continues to be of major importance as they must take into consideration student experiences and cultures. The social, cultural, and academic adjustment process for African Americans varies based on the students’ culture, personal backgrounds and individual experiences not just race. For this research study African American students attending a predominantly White Midwestern institution participated in individual interviews and focus groups to share their experiences. Findings are presented to provide an overview of how best practices and policies regarding engagement, cultural integrity, academic support, awareness, and inclusion can assist in improving the climate and culture of the institution for African American students.

  Rapidly Locating and Accurately Tracking the Center of Mass Using Statically Equivalent Serial Chains

  Ali Almandeel

  Identifying the center of mass location (CoM) provides a significant aid in controlling the balance of humanoid robots. For human beings, the stability of motion is highly influenced by their ability to control their CoM and center of pressure (CoP). Additionally, computing the CoM can prove critical to assessing rehabilitation and in elite sports training. Human body segment parameters can be obtained from anthropometric tables. Their accuracy for a given individual is questioned due to differences in age, race, and fitness level from the sample population. This research presents an estimation technique that uses the statically equivalent serial chain (SESC). A SESC is a representation of any multilink branched chain, like a human or humanoid, whose end-effector locates the CoM. The SESC's construction during an experimental phase depends on the node positions from a motion capture system (like the Microsoft Kinect), and the total mass and CoP from a force plate (like the Wii Balance Board). Additionally, the presence of a static body in the workspace (a walker or chair, for example) to create stability in test subjects is presented. The utility of the presented method as compared to other common methods for CoM estimation is that the force plate is not needed to track the CoM after the SESC is constructed.

  Reading Interventions in Relation to the Ohio Third Grade Reading Guarantee

  Kathryn C. Auletto

  Reading is one of the most critical skills that students learn in their first few years of education. A strong foundation in reading at the early childhood level can promote success in the rest of schooling and beyond. This is especially true for children of poverty; reading abilities and the strong education that follows provide students with opportunities to break the poverty cycle. The importance of reading achievement has a political dimension, as demonstrated by Ohio’s Third Grade Reading Guarantee. This legislation, which has many implications in education, requires that all third grade students who do not pass the Reading section of the Ohio Achievement Assessment must be retained until they are on reading level. In order to prevent this retention, teachers may choose to implement a reading intervention program with students who are at-risk of retention in third grade. The Ohio Department of Education provides districts with research-based reading instructional programs that may be implemented with these students. The list includes Reading Recovery and Orton Gillingham, two reading programs that use different approaches to literacy instruction. The research conducted in this study looks into the factors affecting a low-income school’s decision to select one of these two programs. The research follows a dual case study format, in which interviews were conducted with principals and teachers in the selected high poverty schools. The interviews, along with collected data about these schools and the two programs, provide an illustration of how the Third Grade Reading Guarantee is affecting curriculum, as well as how schools are choosing these reading programs in accordance with the new legislation. The research provides valuable information for low-income schools in this selection process for choosing the appropriate intervention for their struggling readers.

  Reducing Structural Error in Function Generating Mechanisms via the Addition of Large Numbers of Double-Crank Linkages

  Hessein Ashour

  This research presents a methodology for synthesizing planar linkages to approximate any prescribed periodic function. The mechanisms selected for this task are the slider-crank and the geared five-bar with connecting rod and sliding output (GFBS), where any number of drag-link (or double crank) four-bars are used as drivers. A slider-crank mechanism, when comparing the input crank rotation to the output slider displacement, produces a sinusoid-like function. Instead of directly driving the input crank, a drag-link four-bar may be added that drives the crank from its output via a rigid connection between the two. Driving the input of the added four-bar results in a function that is less sinusoid-like. This process can be continued through the addition of more drag-link mechanisms to the device, slowly altering the curve toward any periodic function with a single maximum. For periodic functions with multiple maxima, a GFBS is used as the terminal linkage added to the chain of drag-link mechanisms. The synthesis process starts by analyzing one period of the function to design either the terminal slider-crank or terminal GFBS. A randomized local search is then conducted as the four-bars are added to minimize the structural error between the desired function and the input-output function of the mechanism. Mechanisms have been “grown” in this fashion to dozens of links that are capable of closely producing functions with a variety of intriguing features.

  Relative Performance Evaluation Incentives in CEO Compensation Contracts

  Angela M. Lechermann

  Executive compensation is frequently discussed and criticized by the media, lawmakers, regulators, experts, and the public. The primary issue that companies face when compensating executives is how to align the goals of executives with the goals of various stakeholders in order to motivate executive decisions that increase the value of the company to shareholders, employees, the public, regulators, and others. Academics find that executives’ interests are often best aligned by making compensation contingent on company performance. One method of compensating executives that is frequently discussed is comparing a company’s performance to that of a peer group of companies. This type of incentive is referred to as relative performance evaluation (RPE).The use of RPE in executive compensation is appealing for both executives and shareholders. The appeal for executives is that an incentive can be earned even when performance is weak, as long as it exceeds peers’ performance. Also, when companies offer RPE incentives, shareholders are less likely to pay executives for luck. Finally, many consider RPE incentives to be fairer and more justifiable than other types of incentives.This research examines the use of RPE incentives in CEOs’ compensation contracts among large publicly-traded companies. Our sample includes more than 100 companies across several years. We use hand-collected data from proxy statements filed with the Securities and Exchange Commission to determine the extent of use of RPE incentives in CEO contracts and whether the use of RPE is increasing over time, particularly in years when company performance is depressed. We also compare the characteristics of companies using RPE incentives to those of companies not using RPE, and we collect data on the performance measures, peer groups, time horizons, and payment methods for RPE incentives provided.

  Relative Value and Momentum Weighting for a Concentrated Portfolio of Health Care Stocks

  John P. Klinger

  A key factor in portfolio returns is the weights given to stocks in a portfolio of stocks. Capital Asset Pricing Models indicate that the weight assigned to a stock should be based on its risk premium to the market. In recent years, attention has focused on firm size, relative valuation, and earnings momentum as the appropriate weighting strategies. In this study I focus my attention on large size firms in the health care sector using a concentrated portfolio of the 10 largest holdings in the SPDR Health Care ETF. I use a combination of relative value and momentum weighting strategies to develop portfolio weights for the 10 health care stocks. The performance of the concentrated portfolio is compared to the performance of the SPDR Health Care ETF, the DOW, and the S&P 500 for 2014. Quarterly and annual performance comparisons are made assuming that the concentrated portfolio starts 2014 with a funding level of $5,000,000.

  Research exercise: A Mathematical Model to Calculate an Animals Equilibrium Temperature based on the Environmental Temperature

  Victoria A. Wawzyniak

  Every animal’s temperature is directly correlated to the temperature of the environment that the animal lives in. The animal’s equilibrium temperature can be modeled using mathematical tools based on the temperature of the environment, the amount of solar radiation, and the heating characteristics of the specific animal. Newton’s Law of Cooling can be used to model this sort of phenomena of temperature changes. This mathematical model provides a relation between the unknown temperature and the derivative of this unknown temperature. In this work we will solve this model numerically using different techniques such as the Euler method, the three-term Taylor method, and the Runge-Kutta method. Using these three different mathematical methods, the animal’s body temperature due to the environment can be determined. We use Matlab for all numerical computations.

  Research exercise: Closed Loop Container Glass Recycling in the State of Ohio

  Jonathon P. Caito, David D. Carlos, Josh Obertino Norwood

  Glass recycling is one of the fastest growing recycled materials in the country; however, there is a lot that comes into play in order to determine the efficiency of glass recycling. The state of Ohio is in a unique situation due to the fact that it is in close proximity to a large amount of glass production facilities, both in state and nearby out of state. This allows glass recycling facilities to achieve a high rate of production, as well as keep a relatively high efficiency rate due to low transportation cost. That being said, there is still much that Ohio can improve upon in order to both increase its efficiency and become closer to having a "closed loop" on glass usage. Currently the glass received for recycling outweighs the current demand for glass in Ohio; due to quality issues and differences in product demands, a large portion of the the processed recycled glass is shipped out of state, while raw materials are shipped in to glass manufactures. While this is not the only thing responsible for a huge loss in efficiency, it is also responsible for the unnecessary environmental impact of the excessive use of raw materials. This research will examine possible solutions in order to increase the efficiency and quality of the glass recycling process. Such acts as separate glass curbside recycling and color separation have shown to hold a significant impact on the percentage of the glass material retained form the recycling process, as well as the overall quality.

  Research exercise: Comparative Education System Analysis Between Finland and the United States: A Case Study

  Caroline Ann Goodill

  International student achievement tests have articulated the problem of inequitable education systems around the world. Due to the relatively recent introduction of these tests, scholarly research on the subject has developed as the tests have produced more results. A shared goal of a majority of the research regarding international student achievement is to establish quality education systems. As the United States continuously ranks at or slightly above or below average on the PISA test over the past twelve years, Finland’s consistent success has drawn worldwide attention. For this reason, Finland is the educational system benchmark for this undergraduate thesis.Many authors and scholars have claimed there have been specific Finnish innovations developed in the past decade that directly contribute to Finland’s rise in international student achievement scores. Finland looked to foreign education systems, like Japan, the United States, England, and Sweden, when building and later reforming their own system. In order to help improve American education, it can be beneficial to identify and analyze the programs of the Finnish system that have proven to be successful. The research questions thus guiding this thesis are: What changes have been made in the educational system in Finland that have contributed to improving performance on international assessments? What changes have been made in the United States educational system that are similar to the changes that have been made in Finland? What are the factors contributing to the success of the changes in Finland that could be replicated in the United States?To date, the researcher has identified and begun research on Finland’s part-time special education system, the 9-year comprehensive education system, peruskoulu, and the universal structure of the university teacher education program as three innovations supporting Finland’s educational success. Further research and analysis will continue to evolve over the next two years.

  Research exercise: Drosophila eye model to demonstrate the role of microRNA-277 in Alzheimer's disease

  Ginny Marie Long, Ankita Sarkar

  Alzheimer’s Disease (AD) is a progressive neurodegenerative disorder associated with gradual cognitive impairment and memory decline. As the most common form of dementia, AD currently affects more than 5 million Americans and is expected to affect over 16 million Americans by 2050, according to the Alzheimer’s Association. This disease is characterized by the accumulation of Amyloid-beta 42 (Aβ-42) polypeptides, resulting from the hydrophobic nature of an improperly cleaved transmembrane protein called the amyloid precursor protein (APP). When the APP is cleaved to be 42 amino acids long instead of 40, plaques are formed that alter cellular pathways, inhibit synaptic activity, and initiate neuronal death. Using Drosophila melanogaster as a transgenic model system, we misexpressed Aβ-42 in the differentiating photoreceptors of the developing Drosophila eye. Misexpression of Aβ-42 in the eye results in a strong neurodegenerative phenotype. This project focuses on the impact of a specific microRNA, mir-277, on amyloid-beta-42 mediated neurodegeneration. MicroRNAs act as post-transcriptional regulators of gene expression and work by binding to complementary sequences of mRNA to induce effects such as target degradation, or translational repression. By doing so, microRNAs are capable of preventing protein assembly associated with specific mRNA targets. The results from our studies will be presented.
