Searches For Gravitational Waves From Binary Black Hole Coalescences With Ground-based Laser Interferometers Across a Wide Parameter SpaceRay Pitambar Mohapatra, Satyanarayan 01 September 2012 (has links)
This is an exciting time for Gravitational Wave (GW) theory and observations. From a theoretical standpoint, the grand-challenge problem of the full evolution of a Binary Black Hole (BBH) system has been solved numerically, and a variety of source simulations are made available steadfastly. On the observational side, the first generation of state-of-the-art GW detectors, LIGO and Virgo, have achieved their design goal, collected data and provided astrophysically meaningful limits. The second generation of detectors are expected to start running by 2015. Inspired by this zeitgeist, this thesis focuses on the detection of potential GW signatures from the coalescence of BBH in ground-based laser interferometers. The LIGO Scientific Collaboration has implemented different algorithms to search for transient GW signatures, targeting different portions of the BBH coalescence waveform. This thesis has used the existing algorithms to study the detection potential of GW from colliding BBH in LIGO in a wide range of source parameters, such as mass and spin of the black holes, using a sample of data from the last two months of the S5 LIGO science run (14 Aug 2007 to 30 Sept 2007). This thesis also uses numerical relativity waveforms made available via the Numerical INJection Analysis project (NINJA). Methods such as the Chirplet based analysis and the use of multivariate classifiers to optimize burst search algorithms have been introduced in this thesis. These performance studies over a wide parameter space were designed to optimize the discovery potential of ground-based GW detectors and defining strategies for the search of BBH signatures in advanced LIGO data, as a step towards the realization of GW astronomy

The Mutant Database: Media Franchise Authorship, Creators' Rights, and Teenage Mutant Ninja TurtlesCardenas, Jen 05 1900 (has links)
Teenage Mutant Ninja Turtles (TMNT) is a massive ongoing franchise that began as a 1984 self-published comic book created by Kevin Eastman and Peter Laird. Its history is intertwined with the creators' rights movement and the Creator's Bill of Rights (CBR), which rejected work-for-hire contracts, wherein creative laborers—creative authors—cede authorial control of their labor. Because the production of comic books and their franchises is highly collaborative, intellectual property (IP) rights are often consolidated in a single rights holder—a corporate author—via work-for-hire contracts. Eastman and Laird, as both creative and corporate authors, initially maintained strict control of TMNT licensees, but allowed their employees to retain IP rights over creative contributions to TMNT. However, in 1992, Eastman and Laird sent retroactive work-for-hire contracts to all current and former employees. This TMNT case study illustrates how the CBR represented the conflicting interests of publishers and creative laborers and ultimately reinforced the individualistic view of authorship that undergirds work-for-hire doctrine. Additionally, because IP legal infrastructure uses individualistic discourse to consolidate control of media franchises in one entity that allows authorized individuals access to a shared database of creative expressions that workers can borrow from or add to, media franchises resemble folklore and are made via a database mode of production. The romantic vision of authorship (and authorial control) upon which the CBR was founded ultimately went on to serve publishers rather than creators working for media properties, repeating a pattern that has existed since the inception of copyright and authorship.

As jornadas de junho de 2013 e as estratégias de ação da Mídia Ninja no campo do jornalismoMendonça, Marcela Prado 30 August 2016 (has links)
This research aims to understand how Mídia N.I.N.J.A. (Independent Narratives, Journalism and Action in Portuguese) emerged from political actor within the political field, to a media actor within the media field, and its movement within the journalism field during the Journeys of June 2013 in order to conquer the symbolic capital of visibility. The phenomenon known as "Journeys of June" provides the space of time for this research. In June 2013, the Mídia Ninja (MN) conquered space on the pages of mainstream newspapers in both Brazilian and international presses. In order to understand the object Mídia Ninja, we follow the conceptual construction of Pierre Bourdieu's field, in order to relate the different spheres of activity of this collective actor, analyzing the struggles for symbolic capital and its relationship with the traditional press in the field of journalism. We investigated the Ninja Media as a social movement that acts in social media, based on the authors Maria Gloria Gohn and Ilse Scherer-Warren, in order to understand the collective configuration as a new social movement and analyze its appropriation of new information technologies (ICT's) to the media cyberactivism and the concept of collective action repertoire of Charles Tilly. From the identification of the group's action repertoire, the MN was located in the field of journalism and had their actions related with the actions of traditional media, using the newspapers Folha de S. Paulo and O Estado de S. Paulo. This analysis allowed us to investigate the following hypotheses: 1) Mídia Ninja is a new social movement that has appropriated new information and communication technologies to achieve media visibility; (2) that Mídia Ninja's actions express a kind of symbolic fight for the symbolic capital of the media field that is visible, to the consequent conquest of power within the political field; (3) the actions of Mídia Ninja has generated a collective position within the field recognized by the own journalism agents' field , representatives of the traditional press and finally (4) the Mídia Ninja overthrew the journalism field during Journeys of June. / A presente pesquisa tem como objetivo compreender como a Mídia N.I.N.J.A. (Narrativas Independentes, Jornalismo e Ação) emergiu de ator político, dentro do campo da política, para ator de mídia, dentro do campo das mídias, e sua movimentação dentro do campo do jornalismo durante as Jornadas de Junho de 2013 para a conquista do capital simbólico da visibilidade. O fenômeno conhecido como “Jornadas de Junho” oferece o recorte temporal dessa pesquisa. Em junho de 2013, a Mídia Ninja (MN) ganhou as páginas dos jornais da imprensa tradicional no Brasil e no exterior. Para compreender o objeto Mídia Ninja, seguimos a construção conceitual de campo social de Pierre Bourdieu, com o objetivo de relacionar as diferentes esferas de atuação deste ator coletivo, analisando as lutas por capital simbólico e sua relação com a imprensa tradicional no campo do jornalismo. Investigamos a Mídia Ninja enquanto movimento social de atuação em rede e na rede com base nas autoras Maria da Glória Gohn e Ilse Scherer-Warren, a fim de compreender a configuração do coletivo como novo movimento social e analisar sua apropriação das novas tecnologias da informação e comunicação (TIC’s) para o ciberativismo midiático, bem como o conceito de repertório de ação coletiva de Charles Tilly. A partir da identificação do repertório de ação do grupo, localizamos a MN no campo do jornalismo e relacionamos suas ações com as atividades da imprensa tradicional, utilizando os jornais Folha de S. Paulo e O Estado de S. Paulo. Essa análise nos permitiu investigar as hipóteses de que: (1) a Mídia Ninja é um novo movimento social que se apropriou das novas tecnologias da informação e comunicação para alcançar visibilidade midiática; (2) as ações da Mídia Ninja expressam um tipo de luta simbólica pelo capital simbólico do campo da mídia que é a visibilidade para a consequente conquista de poder dentro do campo político; (3) as ações da Mídia Ninja geraram um posicionamento do coletivo dentro do campo reconhecido pelos próprios agentes do área jornalística, representantes da imprensa tradicional e, por fim, (4) a Mídia Ninja subverteu o campo do jornalismo durante as Jornadas de Junho.

Spjälsäng för en ninjaBlad, Maria January 2011 (has links)
Projektets syfte har varit att för Swedish Ninja ta fram en spjälsäng vars funktioner bygger på mål-gruppens och användarnas behov samt har en stark Swedish Ninja identitet. Det ska vara en säker pro-dukt med enkla form- och konstruktionsklösningar för att förmedla enkelheten i att använda den. En del av projektets syfte var även att kartlägga spjälsängsmarknaden i Sverige som den såg ut våren 2010. Detta gjordes genom marknadsanalyser vilka klargjorde i vilket segment som spjälsängen för Swedish Ninja ska befinna sig, funktions och prismässigt. Med dessa marknadsundersökningar klar-gjordes även vilka befintliga och pålitliga konstruktionslösningar som kom att användas i projektet. Genom användaranalyser har föräldrar redogjort vilka behov de och deras barn har och vad som be-hövs för att tillgodose dessa. Funktioner som efterfrågades var olika steg i sängbotten, en höjbar hu-vudände och mobilitet för lättare transport av spjälsängen inom hemmet. Det är dessa funktioner som kom att skapa produktens karaktär och identitet. Utöver detta undersöktes även alla de säkerhetsanvis-ningar som existerar och vari skillnaden ligger då man designar till ett barn eller en vuxen. Skisspro-cessen är den del av designprocessen där information, krav och idéer arbetas samman till faktiska lös-ningar och som leder fram till slutresultatet, som blev en spjälsäng för en ninja. Denna spjälsäng som med sina lättanvända funktioner och starka identitet skapar det där lilla extra som kommer att få den att överleva generationer.
