description: An onboard target detection, tracking and avoidance system has been developed in this paper, for low-cost UAV flight controllers using AI-Based approaches. The aim of the proposed system is that an ally UAV can either avoid or track an unexpected enemy UAV with a net to protect itself. In this point of view, a simple and robust target detection, tracking and avoidance system is designed. Two open-source tools were used for the aim: a state-of-the-art object detection technique called SSD and an API for MAVLink compatible systems called MAVSDK. The MAVSDK performs velocity control when a UAV is detected so that the manoeuvre is done simply and efficiently. The proposed system was verified with Software in the loop (SITL) and Hardware in the loop (HITL) simulators. The simplicity of this algorithm makes it innovative, and therefore it should be used in future applications needing robust performances with low-cost hardware such as delivery drone applications.

description: In spite of the efforts of the education and mathematics communities, the mathematics background of recent American high school graduates entering American colleges and universities is less than that of their counterparts in other countries and indeed less than that of their counterparts in the U.S. in the early 1960s. Some educators blame the problem on the gap between knowledge and analytical abilities and recommend that instruction should be in the manner of critical thinking. The invention of microcomputers in 1979 was a turning point in applications of computers, and it is believed among educators that microcomputers will play an important role in education and especially as a strong tutorial tool in the form of Computer Assisted Instruction (CAI). This study introduces a new approach by providing a new model that can be used to write educational courseware. The new model, Computer Assisted Instruction And Critical Thinking (CAIACT), uses the strengths of CAI and the skills of critical thinking. An example of how a CAIACT model can be used for teaching Mathematics of Finance is included in this study. The courseware was tested on a sample of 168 students. Statistical analyses were done to test the hypotheses that the courseware developed for Mathematics of Finance did not improve the performance of its users and that the users of courseware did not like using a computer for instruction. The technical aspects of the courseware were also analyzed. As a subsidiary objective this study asked whether students believed that CAI could eliminate possible discrimination by teachers on the basis of sex, race, citizenship, and age, assuming that the instructional material was not biased. The courseware improved significantly the performance of its users, they liked the use of CAI for instruction, they analyzed the courseware favorably, and they believed that CAI could eliminate possible discrimination by teachers.

description: This study was designed to investigate the adoption of television in Cameroon and to analyze its effects on middle-class youths. The research questions to be answered were: (a) what does the phenomenon of television mean to Cameroonian middle-class youths? (b) how do the middle-class youths react to various types of programs and which do they prefer? (c) what aspects of portrayals on television increase the likelihood that Cameroonian middle-class youths will use them as models for their own behavior? (d) what is the relationship of the viewing habits and preferences among male and female middle-class youths? and, (e) does television reinforce the status quo, that is, does television encourage support for the existing political, social, cultural, and economic system?; I conducted a survey of 400 students. The instrument used was a questionnaire (see Appendix A) with fifty questions. It was administered to viewing subjects from selected cities where television is well established. I also analyzed and described the content of television programming to determine whether programs are locally created and produced or imported. The observed results were as expected. 236 of the respondents (59% of N = 400) prefer domestic programming which reinforces the local culture to foreign programming. As also expected, 257 or 64.25% of them said their behavior was influenced more by the local culture than by television. 216 or 54% said television influences the way they dress. 53% of those surveyed said local television programs had more influence on them than say, foreign television programs, local and foreign radio programs. 145 respondents or 36.25% said they watch television 2 or 3 days a week. The results also showed that both males and females are moderate television viewers. A description of the content of television revealed that more than 75% of the total weekly programs are domestically created and produced. Of the total number of domestic programs, political and economic programs, educational and health themes, and cultural/entertainment shows ranked the highest. The results do partly support my original theory. This assumed that the television viewing middle-class youths would have a favorable attitude towards elements of foreign culture and a strong preference for locally produced programs. The analyses also support the theory that television's impact would be pervasive in some aspects as well as stimulate change in others. This assumed, for example, that the forces in control of the new medium will use it to maintain the status quo rather than alter it.

description: We study a crossover from classical to quantum picture in the electron energy statistics in a system with broken time-reversal symmetry. The perturbative and nonperturbative parts of the two level correlation function, $R(ω)$ are analyzed. We find that in the intermediate region, $Δ\llω\sim t_E^{-1}\ll t_{erg}^{-1}$, where $t_E$ and $t_{erg}$ are the Ehrenfest and ergodic times, respectively, $R(ω)$ consists of a series of oscillations with the periods depending on $t_E$, deviating from the universal Wigner-Dyson statistics. These Ehrenfest oscillations have the period dependence as $t_E^{-1}$ in the perturbative part. [For systems with time-reversal symmetry, this oscillation in the perturbative part of $R(ω)$ was studied in an earlier work (I. L. Aleiner and A. I. Larkin, Phys. Rev. E {\bf 55}, R1243 (1997))]. In the nonperturbative part they have the period dependence as $(Δ^{-1}+αt_E)^{-1}$ with $α$ a universal numerical factor. The amplitude of the leading order Ehrenfest oscillation in the nonperturbative part is larger than that of the perturbative part.

Our analysis of EDMs and current LHC constraints shows that, in the case of a 2HDM Type II and Type III, an $\mathcal{O}(0.1)$ CP-violating phase in the Yukawa interaction between $H_1$ (the $125~\textrm{GeV}$ Higgs boson) and fermions is still allowed. For these scenarios, we study CP-violating effects in the neutron EDM and $t\bar{t}H_1$ production at the LHC. Our analysis shows that such an $\mathcal{O}(0.1)$ CP-violating phase can be easily confirmed or excluded by future neutron EDM tests, with LHC data providing a complementary cross-check.

description: In this paper the focus is on two forecasting models for a monthly time series. The first model requires that the variable is first order and seasonally differenced. The second model considers the series only in its first order differences, while seasonality is modeled with a constant and seasonal dummies. A method to empirically distinguish between these two models is presented. The relevance of this method is established by simulation results, as well as empirical evidence, which show that,. firstly, conventional autocorrelation checks are often not discriminative, and, secondly, that considering the first model while the second is more appropriate yields a deterioration of forecasting performance.

title: Measuring an orienteer's performance: a method based on lower rank approximation of asymmetric matrices
Creators: name: Villers Gomez, Sofia
Publisher: name: The Open University
Year: 2015

description: The objective of this thesis is to develop a method that measures the performance of competitors in an orienteering course. The measures proposed will allow the comparison of the orienteer’s performance with other competitors running the same course, and with his/her performance in different courses. This thesis presents two main contributions, the first one refers to an orienteer’s performance measure, and the second one relates to the lower rank approximation theory developed for this research. In the orienteering context, we developed a method that calculates a fitness measure and a navigational measure for each orienteer running a course. This differentiation between physical and navigational skills is an original approach to the orienteering performance analysis, and it allows a clear identification of areas that need improvement to achieve better times in an event. Based on the performance measures of orienteers participating in 100 events that took place in the UK between January 2013 and May 2014, we construct a course technical difficulty measure for green, blue and brown courses. This course difficulty allows the identification of easy and hard courses. On the statistical theory context, this thesis presents a robust and asymmetric lower rank approximation algorithm to reduce matrices with asymmetric outliers into two vectors. This algorithm was based on the robust lower rank approximation algorithm proposed by Maronna and Yohai (2008). This thesis presents two original modifications to this algorithm, which produces better estimates when the data has asymmetric outliers. Those modifications are the definition of an asymmetric objective function, and the use of a robust scale parameter that is updated at each iteration. The proposed modification to the scale parameter caused that the estimates do not depend anymore on initial values and the value reached by the loss function is most of the time better than the point reached without the modification. We also show that this methodology can be applied in contexts other than orienteering.

Free black adaptive responses to the antebellum urban environment: Neighborhood formation and socioeconomic stratification in Alexandria, Virginia, 1790-1850
Creators: name: Blomberg, Belinda
Publisher: name: American University
Year: 2023

description: The role of residence as a response to competition and conflict is explored through hypothesis tests formulated to define variation within the free black population. Documentary data are used to describe this population and to identify free black residential areas and patterning related to socioeconomic rank differences. Historical factors considered include the changing role of legal sanctions imposed on free blacks, race-related social unrest, benevolent societies, abolitionist, and colonization movements, and schools and churches in Washington, D.C. and Alexandria. The methodology consisted of a one hundred percent survey of the tax and census records and information was collected for 632 free black household heads on twenty-nine spatial, social, and economic variables. This approach is directed toward future use in preservation planning and the archaeological investigation of neighborhoods in the city. The first hypothesis tests whether differences in the socioeconomic ranks within the free black population correlate significantly with variables that may represent increased or decreased opportunity in an urban environment. Differences in socioeconomic rank were found to correlate with presence of household in an alley, presence of boarders in a household, and gender of the household head. Differences in the year and ward of residence and color and literacy level of household heads were not associated with differences in socioeconomic rank. Seven post hoc auxiliary hypotheses were generated from the results of Hypothesis 1 and a descriptive analysis of the data set. Hypothesis 2 postulates that in situations of population increase and intergroup conflict the majority of free black residential areas in any given time period will exhibit heterogeneous clustering with regard to the variables occupational opportunity, tenure, and socioeconomic status. The results show that free black households are more apt to segregate themselves by levels of occupational opportunity and tenure regardless of time period. However, as the antebellum period progresses free black residential areas are composed of household heads from the entire range of the socioeconomic hierarchy. Although each residential area has a unique evolution, their development in Alexandria reinforced free black group identity and security in an uncertain antebellum environment.

description: We consider Bayesian statistical inference for univariate time series models where one of the autoregressive roots is close to or equals unity. Classical sampling theory for this type of models is hampered by the vast differences between asymptotic approximations in the stationary case and under the unit root hypothesis. Because of this dichotomy one has to decide early on in an empirical study whether a given time series is stationary or not. The present paper shows that a Bayesian approach allows for a smooth continuous transition between stationary and integrated time series models. Empirical results are presented for time series of annual real per capita GNP for 16 OECD countries.

title: Academic literacies and attitudes of EFL students in a CMC environment
Creators: name: Malik, Altaf ur Rehman
Publisher: name: The Open University
Year: 2015

description: There is a growing volume of research showing that academic literacy is discipline specific. To become proficient in a specific discipline and be a part of a discourse community, learners have to learn ways of communication acquired through understanding and practising the necessary genres associated with that discipline. Both synchronous and asynchronous Computer-mediated communication (CMC) provides opportunities for learners to be a part of that discourse community and learn particular ways of discourse in a collaborative environment. This research investigated how a group of English as a Foreign Language (EFL) learners in a Saudi Arabian university was introduced to academic writing by completing CMC tasks collaboratively. Learners' interactions were examined via a descriptive design to explain how students negotiate academic literacy using synchronous chat and asynchronous discussion boards. Data were gathered from 6 sources: observations, survey questionnaires, texts of participants' online discussion entries, online peer feedback, students' assignments, and interviews. Data were analyzed both quantitatively and qualitatively to investigate how these EFL undergraduate students negotiate their academic literacy in a CMC environment in terms of language functions and focus; how CMC influences both the process and the product of student's academic writing activities; and what EFL students' attitudes were towards CMC in the process of acquiring academic literacy. Data analysis revealed the various discourse functions EFL learners used in their online discussions. Results indicated that computer-mediated communication facilitated students' understanding of tasks and performance of writing activities and promoted collaboration. Analysis of the students' draft and revised essays in the online peer review activities showed that students integrated peers' feedback into their revisions and benefited from such activities although they were not satisfied with the quality and quantity of feedback. A comparison of the students' participation in the face-to-face classrooms with their participation in both synchronous and asynchronous CMC activities afforded through Blackboard® learning management system (LMS) revealed more active interaction during CMC activities in terms of its content and quality. Finally, the EFL students perceived that CMC facilitated their acquisition of academic literacy in academic writing and promoted collaboration despite some limitations.

description: Older adults lag behind their younger counterparts in the use of patient portals, which may limit their ability to engage in health care. A better understanding of the factors associated with portal use among older adults is needed. We examined the proportion of 100 community-dwelling older adults who reported using a portal, the associations between sociobehavioral factors and portal use, and modeled predictors of portal use. Of the 52% who reported using a portal, 28% used the portal on their own, and 24% received assistance from others or had others access the portal on their behalf. After controlling for confounders, only marital status was significantly associated with any portal use. Marital status and patient activation were significantly associated with independent portal use. Further exploration is war-ranted to identify additional factors and the possible mechanisms underlying portal use by older adults.

description: We introduce a machine-learning-based framework for constructing continuum non-Newtonian fluid dynamics model directly from a micro-scale description. Dumbbell polymer solutions are used as examples to demonstrate the essential ideas. To faithfully retain molecular fidelity, we establish a micro-macro correspondence via a set of encoders for the micro-scale polymer configurations and their macro-scale counterparts, a set of nonlinear conformation tensors. The dynamics of these conformation tensors can be derived from the micro-scale model and the relevant terms can be parametrized using machine learning. The final model named the deep non-Newtonian model (DeePN$^2$), takes the form of conventional non-Newtonian fluid dynamics models, with a new form of the objective tensor derivative. Both the formulation of the dynamic equation and the neural network representation rigorously preserve the rotational invariance, which ensures the admissibility of the constructed model. Numerical results demonstrate the accuracy of DeePN$^2$, where models based on empirical closures show limitations.

description: Measurements of the magnetic form factor $B(Q\sp2)$ of the deuteron at momentum transfers $Q\sp2$ = 1.49, 1.74, 1.98 and 2.48 (GeV/c)$\sp2$ are reported. The data were obtained at the Stanford Linear Accelerator Center using the electron beam from the Nuclear Physics Injector. The back-scattered electrons at 180$\sp\circ$ and the recoiling deuterons at 0$\sp\circ$ were detected in coincidence in a large solid-angle double-arm 180$\sp\circ$ spectrometer system. The experimental technique and the extraction of the results are fully described. The results are compared with theoretical models for the magnetic form factor and lead to a better understanding of the short range nucleon-nucleon interaction.

description: Usually, Neural Networks models are trained with a large dataset of images in homogeneous backgrounds. The issue is that the performance of the network models trained could be significantly degraded in a complex and heterogeneous environment. To mitigate the issue, this paper develops a framework that permits to autonomously generate a training dataset in heterogeneous cluttered backgrounds. It is clear that the learning effectiveness of the proposed framework should be improved in complex and heterogeneous environments, compared with the ones with the typical dataset. In our framework, a state-of-the-art image segmentation technique called DeepLab is used to extract objects of interest from a picture and Chroma-key technique is then used to merge the extracted objects of interest into specific heterogeneous backgrounds. The performance of the proposed framework is investigated through empirical tests and compared with that of the model trained with the COCO dataset. The results show that the proposed framework outperforms the model compared. This implies that the learning effectiveness of the framework developed is superior to the models with the typical dataset.

Participants completed a series of online questionnaires that assessed levels of stigma consciousness, feelings toward the university, self-esteem, well-being, loneliness, and self-perceived teaching effectiveness. We hypothesized that stigma consciousness would contribute unique variance to positive feelings toward the university, feelings of well-being, loneliness, and teaching effectiveness. Four hierarchical regression analyses were conducted to determine if stigma consciousness would predict feelings toward the university, feelings of well-being, loneliness, and teaching effectiveness while holding other potential predictors (i.e., gender, age, self-esteem, time spent in the United States, and English proficiency) constant. It was found that stigma consciousness was negatively associated with positive feelings toward the university and well-being, and positively associated with loneliness. However, stigma consciousness was not significantly associated with teaching effectiveness. As the first study to explore this topic, these findings extend the literature by demonstrating that individual differences in stigma consciousness exist among foreign-born individuals. From an institutional standpoint, it is imperative that we understand and establish solutions for the issues that may be encountered by foreign-born professors so that we may continue to recruit and retain such valued and essential members of the American professoriate. Limitations and implications for future research are discussed.

description: A preposterior decision model and a scouting model are used to estimate the economic benefits of an area-wide soybean insect prediction system in Illinois. Results suggest forecast reliabilities of the insect prediction system must exceed 90 percent accuracy before grower profits increase and acres scouted by consultants decrease. Insecticide use, however, can increase or decrease over a range of forecast reliabilities because of the shift from insect consultants to an area-wide public supported insect prediction system. If risk averse behavior is assumed, growers will likely apply more insecticides and hence reduce forecast prediction benefits.

Elastic electron-deuteron scattering at 180 degrees at high momentum transfers
Creators: name: Katramatou, Assimula Theoharis
Publisher: name: American University
Year: 2023

description: Measurements of the magnetic form factor $B(Q\sp2)$ of the deuteron at momentum transfers $Q\sp2$ = 1.49, 1.74, 1.98 and 2.48 (GeV/c)$\sp2$ are reported. The data were obtained at the Stanford Linear Accelerator Center using the electron beam from the Nuclear Physics Injector. The back-scattered electrons at 180$\sp\circ$ and the recoiling deuterons at 0$\sp\circ$ were detected in coincidence in a large solid-angle double-arm 180$\sp\circ$ spectrometer system. The experimental technique and the extraction of the results are fully described. The results are compared with theoretical models for the magnetic form factor and lead to a better understanding of the short range nucleon-nucleon interaction.
State control over the labor process in the Commonwealth Caribbean
Creators: name: Lewis, Linden Forbes
Publisher: name: American University
Year: 2023

description: The main objective of this dissertation is to elucidate the nature of the relationship between the State in the Caribbean and the labor process. Moreover, the dissertation will investigate the extent of, and specific ways in which Commonwealth Caribbean States exercise control over, the labor process, and with what results. The labor process refers to the structure and organization of production. It is a process which revolves primarily around the social relationship of owners of the productive apparatuses and those whom they employ. The dissertation will explore the ways in which the State, as the condensation of powerful social relationships itself, manages to contribute to the maintenance and reproduction of conditions necessary for ensuring the integrity of the labor process. The importance of understanding the relationship between the State and the labor process is that it has implications for understanding the relations of power in society, how and why those relations are kept in place, and the impact which this organization at the point of production has on the wider society. Furthermore, it is hypothesized in this dissertation that the State's survival as an apparatus of power, as a regulatory mechanism, and as a principal social relationship among classes in society is contingent on the efficacy of labor process organization, and the ability of the dominant class to retain its dominance. Any serious examination of the literature germane to this topic would reveal an important lacuna in Caribbean scholarship. What little research has been done in this area has tended to treat the State and the labor process as separate and unrelated phenomena. This omission is all the more surprising considering that, in the Caribbean, working class struggles have historically been linked to demands for participation in the political decision making process. This study therefore attempts to fill this void in Caribbean scholarship and to provide a useful and critical theoretical paradigm within which this phenomenon could be studied in the region. It is also hoped that this research would stimulate academic dialogue about the subject, and perhaps influence policy makers in the process.

description: Two algorithms, and corresponding FORTRAN computer programs, for the computation of posterior moments and densities using the principle of importance sampling are described in detail. The first algorithm makes use of a multivariate Student t importance function as approximation of the posterior. It can be applied when the integrand is moderately skew. The second algorithm makes use of a decomposition: a multivariate normal importance function is used to generate directions (lines) and one dimensional classical quadrature is used to evaluate the integrals defined on the generated lines. The second algorithm can be used in cases where the integrand is possibly very skew in any direction.
