Space Missions Humans are expected to travel to Mars in 2030 for the first time, guided by NASA’s hand. In the article, “Do You Have What it Takes to Colonize Mars? NASA Might Need You” and “America Will Take the Giant Leap to Mars” both authors write about NASA’s future plans of going to space. NASA also said the space mission would not be carried out though if there wasn 't proper safety measures. Space missions could be the turning point of history, but do the risks outweigh the benefits?…

4.1.4 Development of Feed Forward Control model in Simulink To implement feed forward control. Firstly, the transfer function of the linear DC Motor model has to be obtained. Actually in our case, the input of the plant is current so the transfer function of the mathematical model in ratio of angular velocity to current has to be obtained. It is given by: G(s)=Ω_1/I_a =R_A/K_M 1/(T_e s+1) where T_e=(J_meq R_A)/(K_m Cϕ) is electro-mechanical time constant. The feed forward control could be…

democracy. I will also describe majoritarianism, elite theory, and pluralism. Direct democracy was an Athenian system of government in ancient Greece. Direct Democracy is defined as a system of government in which political decisions are made by the people directly, rather than by their elected representatives. In essence, the laws are either voted on or they have a debate about them. An important feature about direct democracy is the fact that is has a legislator. A legislator, a…

could be there as soon as the 2030s. Many suggestions have been made about how to colonize Mars, but only a few have been actually considered feasible. One of these plans uses the natural resources that are already on Mars to colonize it called “Mars Direct”, however due to its straightforwardness, it wasn’t seriously considered by NASA until recently. The main idea…

b. When measuring the resistance value with the Avo 8, possible reasons for varience include a parallax error (not looking at the reading from directly above the meter), a reading error due to less divisions when measuring resistance, or the device not being properly zeroed. When measuring current, there are also fewer division, parallax is still a potential issue, and finally, incorrect zeroing of the meter. Voltage has an additional error, the loading of the meter itself. Alongside this issue,…

AC voltage is the current that comes from an electrical plug. An advantage of AC voltage is the fact that the power of the voltage can be altered with a transformer. Fig.1 graph showing AC and DC current On the other hand DC voltage stands for direct current. This means that the current only flows in one direction. DC can be obtained from: solar cells, batteries etc. in this type of circuit the electrons move from the negative to positive poles. Compared to the AC voltage, DC is much weaker.…

The derivation of maximum power transfer theorem for purely resistive DC circuits. V_L= E x R_L/(R_L+r) P_L= 〖V_L〗^2/R_L = (E^2 〖R_L〗^2/〖(R_L+r)〗^2 )/R_L = (E^2 R_L)/〖(R_L+r)〗^2 Calculating the most favourable value of the load resistor for maximum power transfer from a DC source with a internal resistance. When any arbitrary load resistance may be selected. Let R_L= kr ( k is a positive number) P_L= kr/〖(kr+r)〗^2 E^2= k/〖(k+1)〗^2 E^2/r f = k/〖(k+1)〗^2 = 1/(k+2+k^(-1) )…

1762-IF4 is an Allen Bradley MicroLogix 1200 System with 4 Channel Current/Voltage Analog Input Module. It has a dimension of 90 x 87 x 40.4 mm. It has Delta-Sigma converter and 4 differential (bipolar) inputs. It’s analog operating voltage range is -10 – 10 V DC normal and -10.5 – 10.5 V DC full scale. It’s analog operating current range is 4 – 20 mA normal and -21 – 21 mA full scale. It converts the analog input up to the full-scale range. It enhances the functionality of MicroLogix 1200…

19) What is the difference between a voluntary and captive audience The difference between a voluntary and captive audience is pretty straight forward. A voluntary audience is an audience who gathers because they want to hear the speech. Voluntary audiences attend gatherings, events, and public speaking venues because they want to, not because they have to. A captive audience is the complete opposite, whereas, they attend a gathering, meeting, or speaking venue because they are required or…

As we know, the culture and geography has a deep effect for each country. If the country wants to develop, it should own strong culture background and outstanding geography position. As the most famous and irreplaceable country in the world, Italy has famous culture and unique geography position. At first, we know the famous culture revolution, Renaissance, started at Italy. This revolution was a huge processing that made technology developing and changed people though. Many Italians got profits…
