Efficient Propeller Design | AbstractHow does a helicopter generate enough lift to fly? How does a speedboat get moving fast enough to pull someone on water skis? Here ’s a project on designing propellers to do the job. ObjectiveThe goal of this project is to investigate how changes in chord length affect the efficiency of propellers.IntroductionA propeller‚ like an airplane wing‚ is an airfoil: a curved surface that can generate lift when air moves over it. When air moves over the surface of

The quote shows a strong relation to the efficient market hypothesis (EMH)‚ as it implies that the costs of capital are dependent from the amount of information given by the company. According to my opinion‚ agency theory is a good explanation for costs of capital. Agency theory defines contracts as under which one party – called principal – engages another party – called the agent – to perform service on the principal’s behalf. Concluding‚ the principal delegates

Instructions for Efficient-Frontier Construction a. Estimation The goal is to obtain the raw ingredients – expected returns‚ standard deviations and correlations. Historical data are used for this purpose. As a rule of thumb‚ five years of daily data are probably right (one year should be the absolute minimum). Keep in mind the following: 1) make sure to use the adjusted close prices to calculate returns (so that you won’t have large‚ spurious negative returns due to dividend payments or splits)

people. However‚ I do not think it should be as high as it is when the income of the consumers is not going up with the price of it. The demand for gasoline drives the price of it up. In the future there is going to be a demand for the electronic cars‚ and the price of gasoline is surely going to drop. Theories of supply and demand had their roots in the early 20th cent (Supply and Demand‚ 2010). Theories of Alfred Marshall‚ which recognized the role of consumers in determining prices‚ rather

modification in reuse may convert a particular anecdote to a fictional piece‚ one that is retold but is "too good to be true". Sometimes humorous‚ anecdotes are not jokes‚ because their primary purpose is not simply to evoke laughter‚ but to reveal a truth more general than the brief tale itself‚ or to delineate a character trait in such a light that it strikes in a flash of insight to its very essence. The word ’anecdote’ (in Greek: "unpublished"‚ literally "not given out") comes from Procopius of Caesarea

Is the electric car the car the future? The main reason to buy an electrical car is the reduced CO2 emission. Reducing pollution coming from cars is a great way to fight global warming. It’s not only less pollution it also costs less. Each kilometer you drive in an electric car costs considerably less than with a comparable fuel car. The motor of an electric car also has a great advantage point with its speed. Electrical engines have a one gear box motor‚ it doesn’t have to shift gears. This

Are electric cars a more sustainable method of transport than diesel or petrol powered cars? In this Case Study‚ I explored whether electric cars are as eco-friendly as they claim to be‚ providing a sustainable method of transport that could significantly reduce our carbon footprints if we all ditched the convectional vehicles‚ and changed to electric cars. I found many arguments both for and against electric cars. Electric cars are powered by an electric motor which draws its power from an on-board
