컴퓨터 비전은 사진 또는 동영상의 시각적 정보를 높은 수준으로 이해할 수 있도록 하는 다원적인 연구분야이다. 이 과정은 정보를 일반적 또는 풍부하게 추출하고 추출된 정보를 추론하기 위한 다양한 기법과 방법을 포함한다. 지난 10년간 발전의 큰 도약으로, 딥러닝은 컴퓨터 비전 분야에서 많이 연구되고 있다. 컴퓨터 비전과 딥러닝의 응용 프로그램 중 하나는 다양한 응용 프로그램으로 확장되는 지능형 감시입니다. 지능형 감시에는 보안 시스템, 인적 활동 인식, 교통 관리 및 법 집행 시스템을 포함할 수 있지만 이에 국한되지는 않다. 보안에 중점을 두고 특정 제한 지역 주변의 이물질 탐지, 수배범 식별 또는 비정상적인 활동 감지와 같은 다양한 형태의 범죄 예방이 적용될 수 있다. 비정상적 활동 감지는 일반적으로 학문적 규율에 속하는 정상적인 / 비정상적인 패턴의 존재를 인식하기 위해 심층 학습 구조를 필요로 한다. 패턴의 특이를 인식하기 위해 개발된 접근법이 많지만, 본 논문에서 제안 된 이상 탐지 시스템의 중추로서 딥러닝 기반 이미지 캡션을 사용한다. 제안된 접근 방식은 이미지 캡션 생성(2장)과 그 구현에 초점을 맞추고 있으며, 이를 유능한 모니터링 시스템으로서의 기능을 보여준다. 제 3장에서는 제안된 접근 방식은 특징 벡터가 주어진 단어 임베딩에 장단기 메모리(LSTM) 레이어를 사용한다. 또한, 제안된 접근법은 매우 인기 있는 단어 내장 사전인 GloVe 색인 방법을 사용한다. 제 4장은 특정 환경에서 발생할 수 있는 폭력 활동을 탐지하기 위해 개발된 프로토타입을 검토한다. 결과 캡션이 로우패스 필터와 임계값을 통과하여 경보를 알린다. Computer vision is a multidisciplinary field of study that attempts to enable a high-level understanding of visual information in the form of digital images or videos by computers. The process generally involves the usage of various techniques and manipulation to extract information, generally or richly, and make an inference out of the extracted information. With a great leap of development in the past decade, deep learning has been gaining more popularity in the study of computer vision. One of the real-world applications of computer vision and deep learning is intelligent surveillance which branches out to many different applications. Some of these might include but are not limited to, security systems, human activity recognition, traffic management, and law enforcement system. Under the security focus of its application, various forms of crime prevention can be applied such as detection of foreign bodies around certain restricted areas, identification of wanted criminals, or abnormal activity detection. Abnormal activity detection commonly requires a deep learning architecture to recognize the presence of abnormal/unusual patterns which falls under its academic discipline. While there are many approaches developed to recognize the outlier in the pattern, this manuscript uses deep-learning-based image captioning as the backbone of the proposed anomaly detection system. The proposed approach focuses on image caption generation (Chapter 2) and its implementation to show its function as a capable monitoring system. In Chapter 3, the proposed approach uses the Long-Short-Term Memory (LSTM) layer for word embedding given a feature vector. Also, the proposed approach makes use of the GloVe indexing method which is a highly popular word embedding dictionary. Chapter 4 reviews the developed prototype to detect probable violent activities in a given environment. The resulting caption is passed through a low-pass filter and threshold to trigger the alarm.

Response of Deep Foundations to Seismic Loads in Alabama

Kane, Kevin Marshall Auburn University ProQuest Dissertations & Theses 2013 해외박사(DDOD)

Deep foundations are commonly used as foundation elements for bridges in Alabama. Due to the implementation of the American Association of State Highway and Transportation Officials (AASHTO) Load and Resistance Factor Design (LRFD) Bridge Design Specifications, design of critical and essential bridges will be significantly impacted for the moderate seismic design category of Alabama.Five bridge case studies were provided by the Alabama Department of Transportation (ALDOT) to evaluate the response of typical foundations used for critical and essential bridges. FB-Multi Pier, a program that couples nonlinear structural finite element analysis with nonlinear static soil models, was used to model both the soil and structure (both foundation elements and substructure components) of each case history. These models were loaded with a suite of scaled time-history events to simulate an earthquake. Displacement at the top of the pier and ground surface was recorded, as well as maximum shear force, bending moment, and demand/capacity (D/C) ratio distribution along the length of the driven pile, drilled shaft, or column. The maximum shear force, bending moment, and D/C ratio distributions indicated where the plastic hinge zones could be expected to form in the structure. FB-Multi Pier was also used to develop a family of foundation response curves that were used in SAP2000 to evaluate the performance of the case histories.Pile performance under combined scour and earthquake was reviewed and two different scour depth models were developed for one case history. Buckling criteria for foundations in soft clay or liquefiable soil were also reviewed and compared to two case histories.It was found that scour depth appears to affect the dynamic response of the bridge pier. The pier modeled with 25% scour depth performed worse (structurally) than the same pier modeled with 100% scour depth. This was due to large displacements at the ground surface and large bending moments developing below the ground surface. The pier founded in soft clay over rock performed poorly due to structural failure in the foundations. This was due to flexure failure of the piles. It was also found that drilled shafts embedded in shallow bedrock tend to perform well depending on the natural frequency and structural period of the pier. Recommendations for further research address soil susceptibility to scour and liquefaction, full-scale dynamic load testing, and correlations between the natural and structural period of a bridge pier and its performance during an earthquake event.

The taxonomy, phylogeny and biogeography of the neotropical genus, Verres Kaup (Coleoptera: Passalidae, Proculini)

Marshall, Christopher J Cornell University 2000 해외박사(DDOD)

A taxonomic revision of <italic>Verres</italic> Kaup was conducted. Nine of the 26 species-level names published under <italic>Verres </italic> (including: <italic>Neoverres</italic> Hincks and <italic>Platyverres </italic> Bates), are considered valid. The invalid names consist of 2 <italic> nomina nuda</italic>, 1 unnecessary replacement name, and 14 junior synonyms (5 of which are newly proposed). Three new species are described, raising the complement of valid species to 12: <italic>cavicollis</italic> Bates, <italic> corticicola</italic> Truqui, <italic>deficiens</italic> Kuwert, <italic>furcilabris </italic> (Eschscholtz), <italic>hageni</italic> Kaup, <italic>intermedius </italic> Kaup, <italic>longicornis</italic> (Luederwaldt), <italic>onorei </italic> Boucher and Pardo Locarno, <italic>sternbergianus</italic> Zang, <italic> achoros</italic> Marshall, n. sp., <italic>arion</italic> Marshall, n. sp., and <italic>gilloglyi</italic> Marshall, n. sp. A comprehensive review of passalid beetle morphology, including detailed illustrations of adult and larval external anatomy, was accomplished. The morphological findings are compared to past anatomical work of Passalidae, other scarabaeoid taxa, and Coleoptera in general. A cladistic analysis was conducted of the 12 valid species of <italic> Verres</italic> based on 27 morphological characters of adults and larvae. Exemplar species from <italic>Veturius</italic> Kaup, <italic>Publius</italic> Kaup and <italic>Proculus</italic> Kaup, three closely related proculine genera, were used as outgroups. The analysis produced a single most parsimonious cladogram (length 59, CI 58 and RI 77) that supports the monophyly of <italic>Verres </italic>. The results also support the conclusion that brachyptery (reduced flight wings) has evolved twice in the genus: once in the Mexican species, <italic> V. intermedius</italic> Kaup and once in a clade of species from southern Central America, related to <italic>V. longicornis</italic> (Luederwaldt). Areas of endemism were defined using multiple criteria, including geography, elevation and forest type. Cladistic biogeographic methods were employed to infer the most parsimonious area relationships. The results support the notion that <italic>Verres</italic> has both older Central American components, as well as more recent radiations. Additionally, the results indicate that the Talamancan cordillera is a complex zone with affinities to northwestern South America as well as to nuclear Central America. A biogeographic prediction is made that the newly described species, <italic>V. achoros</italic> Marshall, n. sp., for which no locality information is known, is natively distributed in the eastern Talamancan Cordillera.

The Bleaching Carceral: Police, Native and Location in Nairobi, 1844-1906

Marshall, Yannick Columbia University ProQuest Dissertations & These 2017 해외박사(DDOD)

The Bleaching Carceral: Police, Native and Location in Nairobi, 1844-1906 Yannick Marshall This dissertation provides a history of the white supremacist police-state in Nairobi beginning with the excursions of European-led caravans and ending with the institutionalizing of the municipal entity known as the township of Nairobi. It argues that the town was not an entity in which white supremacist and colonial violence occurred but that it was itself an effect white supremacy. It presents the invasion of whiteness into the Nairobi region as an invasion of a new type of power: white supremacist police power. Police power is reflected in the flogging of indigenous peoples by explorers, settlers and administrators and the emergence of new institutions including the constabulary, the caravan, the "native location" and the punitive expedition. It traces the transformation of the figure of the indigenous other as "hostile native," "raw native," "native," "criminal-African" and finally "African." The presence of whiteness, the things of whiteness, and bodies racialized as white in this settler-colonial society were corrosive and destructive elements to indigenous life and were foundational to the construction of the first open-air prison in the East African Hinterland.

A case study of athletic training educators' sports care responsibilities, service, and professional advancement in athletic training education programs

Alley, Rachael C Marshall University 2012 해외박사(DDOD)

The purpose of this study was to examine the (1) extent of athletic training faculty members, who bear additional duties for intercollegiate sports care, (2) the beliefs of the faculty members who have intercollegiate sports care responsibilities related to these duties being credited for professional advancement, (3) the beliefs of faculty members related to having sport care responsibilities as part of their employment, and (4) faculty perceptions of intercollegiate sports care responsibilities upon promotion, tenure and contract renewal. A sample of 655 certified athletic trainers was identified by the Board of Certification with the primary occupation designation of educator from a population of 7052 certified members who identified themselves as working in the college and university setting. There were 255 surveys returned for a response rate of 38%. The study utilized descriptive statistics, correlations and emergent category analysis. Findings indicate that only 22% of athletic training educators surveyed had institutional sports care responsibilities. These athletic training educators who had institutional sports care responsibilities overwhelmingly indicated that these responsibilities should be counted toward institutional service credit for professional advancement. Reasons given include that (a) sports care responsibilities are part of the job, (b) there is not enough time for other activities, (c) it is a part of supervising students, and (d) it is a service to school and profession. Athletic training academic faculty members overwhelming believe that they should not have institutional sports care responsibilities. The reasons given for this were (a) lack of balance in responsibilities, (b) no time for sports care responsibilities, and (c) needing to spend more time on academic activities. Athletic training clinical faculty believed that they should have some sort of institutional sports care responsibilities. The reasons given were (a) relevance to the job and teaching, (b) an expectation to do clinical work, and (c) faculty can be active, but not necessarily with the institutions sports teams. Overall, athletic training faculty members do not believe that having sports care responsibilities affect one's chances of professional advancement.

Planning in context: A situated view of children's management of science projects

Marshall, Susan Katharine University of California, Los Angeles 2000 해외박사(DDOD)

This study investigated children's collaborative planning of a complex, long-term software design project. Using sociocultural methods, it examined over time the development of design teams' planning negotiations and tools to document the coconstruction of cultural frameworks to organize teams' shared understanding of what and how to plan. Results indicated that student teams developed frameworks to address a set of common planning functions that included design planning, project metaplanning (things such as division of labor or sharing of computer resources) and team collaboration management planning. There were also some between-team variations in planning frameworks, within a bandwidth of options. Teams engaged in opportunistic planning, which reflected shifts in strategies in response to new circumstances over time. Team members with past design project experience (“oldtimers”) demonstrated the transfer of their planning framework to the current design task, and they supported the developing participation of “newcomers.” Teams constructed physical tools (e.g. planning boards) that acted as visual representations of teams' planning frameworks, and inscriptions of team thinking. The assigned functions of the tools also shifted over time with changing project circumstances. The discussion reexamines current approaches to the study of planning and discusses their educational implications.

This study investigates the implementation of science instruction in a low SES/high minority district, and the experiences of individuals in an elementary principal network who inform science standards and curriculum implementation. This study s. Given the transformative nature of instruction the Next Generation Science Standards (NGSS) advocates, principals' success will depend on their understandings of science instruction, and their ability to support their staff through resources, ti. This study employs a mixed-methods multiple-case design (Yin, 2009) to gain an in-depth understanding of the decisions about science made by school principals, as well as to understand the social capital in the networks of elementary principals. Overall, this study sheds light on how a principal's science social network impacts how they make sense of science policies and therefore science implementation. It was found that those who have discussions with various people in their network r. Recommendations from this study includes promoting community science thinking, the need to create transformative spaces for administrative learning, and that there are benefits to enabling principals as community leaders.

Fugitive Slaves and Community Creation in 19th-Century Kenya: An Archaeological and Historical Investigation of Watoro Villages

Marshall, Lydia Lee Ann Wilson University of Virginia 2011 해외박사(DDOD)

Integrating the analysis of archaeological, oral historical, and documentary data, this dissertation examines the creation of new communities by people escaping slavery in 19th-century Kenya. In Swahili, runaway slaves were known as watoro. This project investigates the creation of watoro communities through a dual focus on inter- and intra-group relationships. First, it explores the relative economic integration of these nascent groups into regional networks. Second, given the social and cultural diversity of people enslaved on the coast, this dissertation examines the extent to which watoro communities developed homogenized sociocultural norms or, alternately, maintained long-term cultural heterogeneity. Two fugitive slave sites were excavated, the 1840s settlement Koromio and the 1880s settlement Makoroboi; these excavations were house-focused in order to facilitate inter-household analysis of artifact distributions. For comparative archaeological data, Amwathoya---a Giriama homestead close to and contemporaneous with Makoroboi---was also excavated; the Giriama were one of the most populous ethnic groups in the 19th-century coastal hinterland. In addition, 40 interviews focused on oral history were conducted with elders living near the three excavated sites. This project's analysis of watoro economic organization highlights the concurrent pressure that such refugees faced in order to engage with some outsiders while restricting contact with others. For example, Koromio and Makoroboi's locations point to defensive strategies in settlement placement. However, whether through interactions with British missionaries at Makoroboi or intensive participation in regional trade at Koromio, these villages' attempts to connect with outsiders are equally apparent. This dissertation's inquiry into watoro cultural plurality encountered more interpretive dissonance between different evidentiary types. Homogenous architectural remains at both Koromio and Makoroboi suggest shared house style may have been a means to reinforce a shared identity. Oral and written historical data revealed additional non-material means by which group cohesion may have been strengthened, including communal Christian worship at Makoroboi. Yet artifact distributions within both watoro sites consistently reflect inter-household heterogeneity in cultural practice, suggesting that earlier cultural affiliations also continued to be both relevant and expressed. This dissertation's analyses highlight the fractal and unstable nature of not only watoro identity but also identity more generally.

Toward a Kripkean concept of number

Marshall, Oliver R City University of New York 2016 해외박사(DDOD)

Saul Kripke once remarked to me that natural numbers cannot be posits inferred from their indispensability to science, since we've always had them. This left me wondering whether numbers are objects of Russellian acquaintance, or accessible by analysis, being implied by known general principles about how to reason correctly, or both. To answer this question, I discuss some recent (and not so recent) work on our concepts of number and of particular numbers, by leading psychologists and philosophers. Special attention is paid to Kripke's theory that numbers possess structural features of the numerical systems that stand for them, and to the relation between his proposal about numbers and his doctrine that there are contingent truths known a priori. My own proposal, to which Kripke is sympathetic, is that numbers are properties of sets. I argue for this by showing the extent to which it can avoid the problems that plague the various views under discussion, including the problems raised by Kripke against Frege. I also argue that while the terms 'the number of F's', 'natural number' and '0', '1', '2' etc. are partially understood by the folk, they can only be fully understood by reflection and analysis, including reflection on how to reason correctly. In this last respect my thesis is a retreat position from logicism. I also show how it dovetails with an account of how numbers are actually grasped in practice, via numerical systems, and in virtue of a certain structural affinity between a geometric pattern that we grasp intuitively, and our fully analyzed concepts of numbers. I argue that none of this involves acquaintance with numbers.
