The aim of this thesis is to design a mechanical position securing of hydraulic elevating systems for stage technology. The first part includes an overview of present state of elevating systems and their securing solutions. The second part determines technical parameters and design of a chosen solution together with control and design calculations. Final part analyses suggested solution in terms of security.

Esta pesquisa aborda as possibilidades de dramaturgia e de presença que as novas tecnologias da Era Digital oferecem para o fenômeno teatral a partir da observação e reflexão do processo de criação dos espetáculos de Teatro Expandido realizados pela companhia de teatro Os Satyros durante os anos de 2014 e 2015. Usando a abordagem metodológica de pesquisa/ação (Michel Thiollent), as investigações empíricas resultaram na dramaturgia e encenação dos sete espetáculos do projeto E se fez a humanidade ciborgue em sete dias. A partir da revisão bibliográfica baseada em pensadores do teatro como Béatrice Picon-Vallin, Josette Féral, Silvia Fernandes, Erika Fischer-Lichte, Marcelo Denny e Jeniffer Parker-Starbuck, bem como em cientistas sociais e estudiosos da Comunicação como Slavoj ?i?ek, Jürgen Habermas, Zygmunt Bauman, Manuel Castells e Shanyang Zhao, são analisados aspectos do processo de criação de cenas em que as tecnologias contemporâneas contribuíram para formas expandidas de presença e dramaturgia, do ponto de vista do diretor-dramaturgo. A pesquisa visa contribuir para a discussão das potencialidades tecnológicas do teatro contemporâneo. Este trabalho se dirige a alunos de graduação e pós-graduação interessados nas artes cênicas contemporâneas, encenadores interessados em tecnologia da cena e formas expandidas de dramaturgia. / This research discusses the possibilities of playwright and presence that the new technologies of the Digital Age offer to the theatrical phenomenon, based on the observation and thinking of the creation process of the augmented theater performances developed by the theater company Os Satyros during 2014. Following the action research methodology proposed by Michel Thiollent, the empirical investigations resulted in the dramaturgy and mise-en-scène of the seven performances of the project \"And so was the Cyborg Mankind made in seven days\". From the bibliographic review based on theater thinkers such as Béatrice Picon-Vallin, Josette Féral, Silvia Fernandes, Marcelo Denny and Jeniffer Parker-Starbuck, as well as social scientists such as Slavoj ?i?ek, Jürgen Habermas, Zygmunt Bauman, Manuel Castells and Shanyang Zhao, a series of scenes and investigations made in the project are analysed. The research aims to contribute to the discussion of the potentialities of contemporary theater. It adresses stage arts graduation and post-graduation students, theater directors interested in stage technology and hybrid stage artists.

This dissertation examines the role of public investments in inducing small firms to develop risky, early-stage technologies. It contributes to expanding our understanding of the consequences of research, innovation, and entrepreneurship policies and programs by investigating in more depth the effect of the Small Business Innovation Research (SBIR) program on the innovation effort, ability to attract external capital, and other metrics of post-entry performance of small business start-ups using a new sample and estimation approach. Unlike prior R&D subsidy studies that concentrated almost exclusively on European countries, this dissertation focused on small business start-ups in the United States using a new scientific survey of new firms. It integrated the Kauffman Firm Survey (KFS) from the Ewing Marion Kauffman Foundation with the SBIR recipient dataset from the U.S. Small Business Administration (SBA) and used advances in statistical matching to achieve better comparability between the treated and control groups of small business start-ups. The integrated KFS-SBA dataset, which contains both recipient and non-recipient small firms, and statistical matching allowed us to empirically construct the counterfactual outcomes of SBIR recipients. This dissertation balanced the pre-treatment characteristics of SBIR recipients and non-recipients through propensity score matching (PSM). It constructed the comparison sample by identifying non-recipients with nearly identical propensity scores as those of SBIR recipients. Consistent with the propensity score theorem, observations with the same distribution of propensity scores have the same distribution of observable characteristics. PSM made the comparison and treatment samples homogenous except in SBIR program exposure, making the fundamental assumption of ignorability of treatment assignment more plausible. Using the realized outcomes of observationally similar non-recipient start-ups as the counterfactual outcomes of SBIR recipients, we found empirical evidence of the input additionality effect of the SBIR program. Had they not applied for and granted SBIR R&D subsidies, recipient start-ups would have spent only $185,000 in R&D, but with SBIR their R&D effort was significantly increased to $663,000, on average. The treatment effects analyses also found a significant positive effect of SBIR on innovation propensity and employment. However, it appears that public co-financing of commercial R&D has crowded-out privately financed R&D of small business start-ups in the United States. A dollar of SBIR subsidy decreased firm-financed R&D by about $0.16. Contrary to prior SBIR studies, we did not find any significant "halo effect" or "certification effect" of receiving an SBIR award on attracting external capital. However, we discovered a different certification effect of the SBIR program: SBIR grantees are more likely to attract external patents. This finding also confirms that innovation requires a portfolio of internal and external knowledge assets as theorized by David Teece and his colleagues. This dissertation's empirical results may be relevant to the Small Business Administration, SBIR participating agencies, the U.S. Congress, other federal, state and local policymakers, small high-tech start-ups, and scholars in the field of science, technology, and innovation policy.
