    The rising cost of oil coupled with the need to reduce pollution and dependence on foreign suppliers has spurred great interest and activity in developing alternative aviation fuels. Although a variety of fuels have been produced that have similar properties to standard Jet A, detailed studies are required to ascertain the exact impacts of the fuels on engine operation and exhaust composition. In response to this need, NASA acquired and burned a variety of alternative aviation fuel mixtures in the Dryden Flight Research Center DC-8 to assess changes in the aircraft s CFM-56 engine performance and emission parameters relative to operation with standard JP-8. This Alternative Aviation Fuel Experiment, or AAFEX, was conducted at NASA Dryden s Aircraft Operations Facility (DAOF) in Palmdale, California, from January 19 to February 3, 2009 and specifically sought to establish fuel matrix effects on: 1) engine and exhaust gas temperatures and compressor speeds; 2) engine and auxiliary power unit (APU) gas phase and particle emissions and characteristics; and 3) volatile aerosol formation in aging exhaust plume

    Mestrado em FinançasO seguinte trabalho consiste em uma avaliação do valor das ações da Samsung Electronics Co., Ltd. para o ano 2020, os pressupostos adotados para a previsão dos próximos cinco anos (2020F-2024F) foram baseados no desempenho histórico dos últimos quatro anos (2016-2019). Este trabalho foi elaborado em conformidade com as recomendações do CFA Institute. Eu escolhi fazer este trabalho sobre a Samsung Electronics Co., Ltd. devido a magnitude e presença global da marca através dos seus produtos e serviços nas diversas indústrias e setores onde atua. Além disso, a minha empatia pessoal com a marca que sempre utilizei desde a minha juventude motivou e ajudou-me a tomar esta decisão. O principal método utilizado para a avaliação foi o método do Fluxo de Caixa Descontado, cujo resultado definiu o preço-alvo de €68 624. Também foram utilizados métodos relativos, do qual os resultados encontrados também reforço a recomendação da COMPRA. Apesar da presente situação de pandemia global onde existe algum grau de incerteza quanto ao final do vírus e das suas consequências, o início do uso de tecnologia 5G em diversos países irão valorizar a ação. No entanto, levando em consideração o grau de incerteza causado pelo COVID-19 e o preço alvo alcançado, emitimos uma recomendação de COMPRA com risco médio.The following work consists of an Equity Research of Samsung Electronics Co., Ltd. for the year ending 2020F, the assumptions adopted for the forecast of the next five years (2020F-2024F) were based on the historical performance of the past four years (2016-2019). This work was written in accordance with the recommendations of the CFA Institute. I choose to evaluate Samsung Electronics Co., Ltd. on the back of the magnitude and global presences of the brand through its products and services across several industries and sectors where it operates. In addition, my personal empathy with the brand that I have always use since my youth have also motivated and helped me taking this decision. This work was written contemplating public information available until November 3rd, 2020, hence, any information or event after this date has not been considered. The main method used for the valuation was the Discounted Cash Flow method, in which the result set the price target of €8361; 68 624. Relative methods were also used, which reinforced the BUY recommendation. Despite the current situation of global pandemic where some degree of uncertainty regarding the end of the pandemic and its effects, the starting of the 5G utilization in several countries will boost the stock value. Nonetheless, considering the current global pandemic and the target pricing, we issue a BUY recommendation with medium risk.info:eu-repo/semantics/publishedVersio
