Avaliação de produtos aerofotogramétricos alternativos com câmaras digitais não métricas de pequeno formato em voo apoiado. / Evaluation of alternative products aerophotogrammetrics with digital cameras no metrics in small formats in flight supported.

Émerson Andrade Diniz 20 June 2016 (has links)
Os produtos cartográficos gerados pelo processo de Aerolevantamento são uma importante ferramenta de análise e tomada de decisões na engenharia moderna. Por outro lado a crescente demanda de projetos está levando pesquisadores a buscarem meios mais rápidos, econômicos e eficientes para obter bons produtos. Dessa maneira, vem surgindo novos equipamentos e produtos nessa área. Paralelamente, com o advento do posicionamento por satélite é possível um maior controle da qualidade cartográfica e a verificação da eficácia desses novos produtos. O presente estudo analisa diferentes tecnologias associadas ao uso da câmara digital não métrica de pequeno formato, como a HASSELBLAD H4D-31, com a utilização do Posicionamento por Ponto Preciso associado a um sistema inercial com e sem a utilização de uma base de referência (voo não apoiado), para a elaboração de ortofotos e cartas. Com relação à precisão geométrica e atendimento do padrão brasileiro de qualidade foram testadas comparativamente essas e outras alternativas, contando com dados da RBMC e apoio suplementar de campo. O produto resultante foi analisado também quanto à eficácia no que se diz respeito à boa qualidade da imagem com a identificação dos objetos em campo para utilização em projetos de engenharia. Ao final pode-se dizer que o produto foi validado, quanto à qualidade informativa e quanto à precisão necessária, atingindo o PEC classe A, para a escala 1:2.000. Ou seja, esse produto é uma alternativa viável tecnicamente e de menor custo, para aplicações como as apresentadas no presente trabalho. / The cartographic products generated by Aerial Survey process is an important tool for analysis and decision in modern engineering. On the other way the growing demand for projects is leading researchers to seek ways more faster, economical and efficient to get good products. In this way, are emerging new equipments and products in this area. At the same time, with the advent of satellite positioning it is possible greater control of cartographic quality and checking the effectiveness of these new products. This study analyzes different technologies associated with the use of the digital camera not metric of small-format, as the Hasselblad H4D-31, using the Positioning Precise Point associated with an inertial system without the use of a reference base (flight not supported ), for the development of orthophotos and maps. Regarding the geometric precision and care of the Brazilian standard of quality we were tested compared these and other alternatives, with data RBMC and additional support field. The resulting product was analyzed as well as the effectiveness as it relates to the quality of the image with the identification of field objects for use in engineering projects. At the end it can be said that the product was validated information as to quality and as to the necessary precision, reaching the PEC class A, to 1: 2000. That is, this product is a technically feasible and low-cost alternative for applications such as those presented in this work.

Neige électronique - L'effet vidéo / Electronic Snow – The Video Effect

Heristchi, Vincent 08 December 2010 (has links)
Si la vidéo est d’un usage courant à la télévision et dans la pratique amateur depuis plusieurs décennies, sa mise en contact avec des films tournés sur pellicules 16 ou 35mm traditionnelles est plus occasionnelle, tout en offrant de nouvelles possibilités esthétiques. En conservant la texture particulière de la vidéo dans un mélange et une confrontation des formats, un effet peut se produire. La création de cet « effet vidéo » est l’objet de notre étude. Que peut l’apparition d’une image vidéo, définie et lisible comme telle, à l’intérieur d’une oeuvre de fiction ou de documentaire dont le support de référence est le celluloïd ? Nous examinerons ainsi certains films de [notamment] Robert Kramer, William Klein, Michael Haneke, Fritz Lang, Jean-Luc Godard, Atom Egoyan, David Cronenberg, David Lynch, Abbas Kiarostami, Abel Ferrara, Wim Wenders, Chris Marker ou Jean-Daniel Pollet. Ayant déterminé le support de référence, nous constaterons que ces images renvoient à un type particulier d’effet vidéo [télévisuel, de surveillance ou amateur-intime], pour étudier ensuite comment ces données peuvent être perverties. Nous analyserons comment la vidéo peut perdre toute justification narrative à l’intérieur de l’œuvre, et infléchir par sa seule texture l’émotion du spectateur, pour éventuellement « faire l’image » [pour reprendre l’expression de Samuel Beckett]. Enfin, en rendant sa nature instable, nous constaterons que l’effet vidéo peut permettre les écarts d’un souffle poétique. / Video is currently used on television and as an amateur format, and has been for a few decades. But its mixing with feature movies shot on traditional 16 or 35 millimetres is more occasional, even if it can offer new aesthetical possibilities. By keeping the particular texture of video, in a mix and a confrontation of formats, an effect can occur. The creation of that “video effect” is the subject of this study. What can create a video image [defined and readable as video] when a fiction or a documentary’s reference of format is on celluloid? To that purpose, some films directed by Robert Kramer, William Klein, Michael Haneke, Fritz Lang, Jean-Luc Godard, Atom Egoyan, David Cronenberg, David Lynch, Abbas Kiarostami, Abel Ferrara, Wim Wenders, Chris Marker or Jean- Daniel Pollet will be investigated. These images determine a particular video effect [television, CCTV or amateur-intimate], and its constituting elements can be altered. Video can also lose all its narrative justification and influence the audience’s emotions only through its texture, in order to eventually « make the image » [in reference to Samuel Beckett’s short story]. Finally, by creating instability in the nature of its constitution, the video effect can contain the openness of a poetic whisper.

An Evaluation of NLP Toolkits for Information Quality Assessment

Karlin, Ievgen January 2012 (has links)
Documentation is often the first source, which can help user to solve problems or provide conditions of use of some product. That is why it should be clear and understandable. But what does “understandable” mean? And how to detect whether some text is unclear? And this thesis can answer on those questions.The main idea of current work is to measure clarity of the text information using natural language processing capabilities. There are three global steps to achieve this goal: to define criteria of bad clarity of text information, to evaluate different natural language toolkits and find suitable for us, and to implement a prototype system that, given a text, measures text clarity.Current thesis project is planned to be included to VizzAnalyzer (quality analysis tool, which processes information on structure level) and its main task is to perform a clarity analysis of text information extracted by VizzAnalyzer from different XML-files.

INFLOW : Structured Print Job Delivery / INFLOW : strukturerade jobbleverans

Buckwalter, Claes January 2003 (has links)
More and more print jobs are delivered from customer to printer digitally over the Internet. Although Internet-based job delivery can be highly efficient, companies in the graphic arts and printing industry often suffer unnecessary costs related to this type of inflow of print jobs to their production workflows. One of the reasons for this is the lack of a well-defined infrastructure for delivering print jobs digitally over the Internet. This thesis presents INFLOW - a prototype for a print job delivery system for the graphic arts and printing industry. INFLOW is a web-based job delivery system that is hosted on an Internet-connected server by the organization receiving the print jobs. Focus has been on creating a system that is easy to use, highly customizable, secure, and easy to integrate with existing and future systems from third-party vendors. INFLOW has been implemented using open standards, such as XML and JDF (Job Definition Format). The requirements for ease-of-use, high customizability and security are met by choosing a web-based architecture. The client side is implemented using standard web technologies such as HTML, CSS and JavaScript while the serverside is based on J2EE, Java Servlets and Java Server Pages (JSP). Using a web browser as a job delivery client provides a highly customizable user interface and built in support for encrypted file transfers using HTTPS (HTTP over SSL). Process automation and easy integration with other print production systems is facilitated with CIP4’s JDF (Job Definition Format). INFLOW also supports"hot folder workflows"for integration with older preflight software and other hot folder-based software common in prepress workflows.

Data Security Architecture Considerations for Telemetry Post Processing Environments

Kalibjian, Jeff 10 1900 (has links)
Telemetry data has great value, as setting up a framework to collect and gather it involve significant costs. Further, the data itself has product diagnostic significance and may also have strategic national security importance if the product is defense or intelligence related. This potentially makes telemetry data a target for acquisition by hostile third parties. To mitigate this threat, data security principles should be employed by the organization to protect telemetry data. Data security is in an important element of a layered security strategy for the enterprise. The value proposition centers on the argument that if organization perimeter/internal defenses (e.g. firewall, IDS, etc.) fail enabling hostile entities to be able to access data found on internal company networks; they will be unable to read the data because it will be encrypted. After reviewing important encryption background including accepted practices, standards, and architectural considerations regarding disk, file, database and application data protection encryption strategies; specific data security options applicable to telemetry post processing environments will be discussed providing tangible approaches to better protect organization telemetry data.

Adaptace zahraničních televizních formátů v České televizi od 90. let do současnosti / The adaptation of foreign TV formats on Czech television from the 90's until present time

Chudárková, Adéla January 2017 (has links)
Teoretickým východiskem této práce je fenomén globalizace, který pronikl do všech domén včetně mediální, jejíž součástí jsou právě televizní formáty, o kterých tato neboť v sobě mísí prvky globální a zároveň lokální kultury, kdy na základě zakoupení zahraniční licence vzniká celá řada lokálních verzí, jež jsou lokálními specifiky dané kultury. Jedná se o stále vzrůstající h počátků, spojených s formáty, rozštěpil mezi všechny žánry, včetně dramatické tvorby. Tato práce se soustředí na adaptace zahraničních televizních formátů v České televizi. Mapuje nejen vývoj tohoto trendu v jediném českém veřejnoprávním televizním médiu, ale taktéž se věnuje důvodům, které vedou ke koupi zahraničních licencí pro médium, jehož výsadou by měla být původní tvorba. Právě otázka veřejnoprávnosti a s ní se pojící specifika výběru obsahu pro toto médium jsou pilířem této diplom

Evelyn Cameron: a study in three parts of her photography, diary, and life in Montana

Van Genderen, Kate 05 September 2017 (has links)
Evelyn Jephson Cameron (1868-1928) was born to a wealthy merchant family outside London. At the age of twenty-five, she moved to Terry, Montana to raise horses and homestead with her husband, Ewen Cameron. Evelyn Cameron recorded their time in eastern Montana in her daily diary entries, which span over thirty-five years from 1893 to 1928. She became a self-taught professional photographer, and made thousands of photographs with large-format cameras of the people in the towns of Terry, Fallon, and Marsh. She photographed the landscape, birds, and other animals she kept as pets or encountered in the wild. She wrote in her private diary nearly every day, offering a first-person point of view of life for women in the late nineteenth-century in the American West. This thesis focuses on three particular aspects of Cameron’s life. The first chapter focuses on spaces or mediums that Cameron had access to that offered her autonomy and privacy, things which were often difficult for women to find at this time. These spaces and mediums include her photography, her diary, and her darkroom, all of which gave her different sorts of calm or control. The second chapter delves into Cameron’s photographic portraits of herself and other women, looking into how women portrayed themselves and others in the American West. Cameron depicted herself as a part of the natural world, and she also did so when capturing other women. The final chapter analyzes Cameron’s identity as a Montanan, from her conscious choice to move there to her refusal to return to Britain permanently. She gained American citizenship in 1918 and took living in Montana seriously. Her diary reveals a deep awareness of the natural world and records accomplishments and events that help to build and strengthen her relationship with her chosen home. / Graduate / 2018-08-25

網路媒體報導式廣告內容分析:內容、表現形式與訴求 / A comparative research of the advertorial in the online media: content, format and appeal

謝子萱, Hsieh, Tzu Hsuan Unknown Date (has links)
隨著網路科技的普及、傳播技術的革新,消費者的閱聽偏好也日漸傾向網路媒介,這不僅令許多傳統媒體亟欲轉型,將經營版圖拓及至網路平台,改以「平網整合」的方式經營,更讓許多「原生於網路」的內容網站應運而生。而媒體與廣告主配合製作的「以報導之名,行廣告之實」的報導式廣告,過去多應用於平面媒體,而今在網路媒體中的應用亦多不可數。   過去學者研究報導式廣告,多半分析其在平面媒體中的特色、廣告設計,或辨識程度、識破程度與主題一致性等,少有對網路媒體中之報導式廣告的內容、表現形式與訴求進行內容分析者。   故本研究欲探討平網整合媒體模式之網路媒體,以及原生內容網站中的報導式廣告,在廣告訊息內容、表現形式,與廣告訴求之間的差異情形。本研究聚焦於專營女性題材之網路媒體,平網整合媒體模式之網路媒體選定「VOGUE」作為代表,而原生內容網站中選定「妞新聞」(Nius News)作為代表,並以內容分析法探討其在不同媒體類別、不同商品類別中之報導式廣告差異。   本研究發現- 不同定位的媒體網站,在報導式廣告的呈現特色上有顯著差異,平網整合模式經營的VOGUE,其報導式廣告有更明顯的「直接性」、「一般性」、「商業性」;原生內容網站模式經營的妞新聞,則相對更「間接性」、「特殊性」、「生活性」。 商品特性之差異,也會影響報導式廣告的廣告策略,如偏「感性」層面的美妝類產品,偏好使用大量的圖像,並帶有強烈的行動呼籲,而偏「理性」層面的保養類產品,偏好多次強調產品名稱,相對直接、平實的呈現廣告內容,而生活用品類則視其產品類別而定,若偏向理性的一般類商品,通常是採「解決問題」導向,若是感性類的商品,則更偏好採取「情感共鳴」導向。 / With the popularity of Internet technology, the dissemination of technology updates, more consumers prefer to access the media through the Internet, resulting in many traditional media try to expand the network platform, and actively transform to the Print-Online integration model. At the same time, there are many "Digital native" content websites join the competition. Many scholars have studied the “Advertorial”, but they only focus on the characteristics, design, or degree of identification in the print media. There is little analysis of the contents, expressions and advertising appeal in the online media. The results of the study found that – Different media websites have significant differences in the advertorial. The VOGUE, which is operated by the Print-Online integration model, has more "direct", "general", "commercial". The Nius News, which is the content website of the "Digital native", relatively more "indirect", "special", "daily ". Differences in product property also affect the advertising strategies of the advertorial. Such as the beauty products have the property of "Emotional", preferring to use many images, and with a strong call action; the skin care products have the property of "Rational", preferring to repeatedly emphasize the product name, relatively straightforward presentation of advertising content. The category of daily commodies is determined by the type of product. The product classified as "Rational", is usually taken to "solve the problem" strategy, but the product classified as "Emotional" is preferred to take "emotional resonance" strategy.

To realize the intension of resources sharing in the public libraries, university libraries and private organizations which have alternative formats materials available in Taiwan. The study adopt qualitative interview research method, and choose 12 units which provide services to visually impaired people with quite scale. The study gets results in three aspects: I. Bibliographies of visually impaired materials are offered by centralized union catalog. 1.Visual Impairment Information System: First, it can be not to buy and produce materials in duplicate with respect to organizations. But timing of producing alternative materials is still need to be considered. Second, there is another way to find materials, but the interface of the system should be more friendly with respect to readers. 2.The intensions and difficulties of sharing and cooperation of visually impaired organizations. (1)12 units have the same responses of willing to participate in the cooperation: The need can be satisfied with bibliographical sharing when visually impaired people find materials. Every organization has the same opinion not to produce and to record books in duplicate. (2)There are three aspects of difficulties of sharing and cooperation: systematic, mental and expectant difficulties. 1)Bibliographies can be connected and accessed by API program, and the library designate provides the cost of API program. 2)The organization with less resources hope to cooperate as soon as possible to increase resources for available. 3)The organization with rich resources demand for performance, achievement and feedback. II. Resources sharing and interlibrary loan 1.Electronic full-text materials are hard to share, and access the materials with single authentication. 2.Providing home delivery service of print materials in alternative formats and audio books will have been more efficient. 3.Formulate the goals, meanings, roles and functions of cooperated organizations. III. The model of sharing and cooperation in visually impaired resources 1.Centralized union catalog and distributed services are recommended. 2.Producing materials in alternative formats is professional. Blind-used computers are developing continuously. Library designate should give advice, assistance and supports.
