Geiger calculateer and its control unit - Lab Report ExampleThe behavior is illustrated inform of a curve of pulse height against utilise voltage. utilize the count rate C1 (beginning of the plateau) and the count rate C2 (almost 100 to 10 volts beyond C1). Both count rates were allocated operating voltages V1 and V2 respectively. The values of V and C were employ to determine the slope of the plateau using an equation.Once the system is set up in an optimum condition, source 1 is placed on the develop holder and the number of count rates per second is measured as N1. While the source is still in place, source 2 is placed in the holder and the equivalent count rate per second interpreted, as N12. Source 1 is now removed and the number of count rates per second is taken as N2. Finally, this can be used to calculate the dead time.The slope and the percentage slope of the curve can also be worked out from the count rates. The period of time, during and immediately fol unkepting an i onization event, when the system is insensitive to a further radiation, is referred to as the Dead time. After placing the material in the holder and riding horse the voltage to a certain value, we stills didnt record any count rate until we attained a certain value of EHT. This is because the energy is very low below that point to be able to separate them very fast. On the other hand, the behavior of the system depended on magnitude of the potential difference applied between the anode and the cathode.Radioactive material can be used to determine the operating voltage of the Geiger counter, the slope percentage of the plateau and the dead time of the counter. This plain involves radioactive material and recording its EHT and counts rate at a certain amount of time.The count measure occurs due to the radiation released and emitted by the material in the holder. When a specimen or material is in exited state, it means that it has absorbed

Chinese new year Essay Example | Topics and Well Written Essays - 500 words

Chinese new course of instruction - Essay ExampleAn analytical report of the Chinese New Year festivities establishes the validity of this statement.The Chinese New Year is lunar, commencing on the first day of the new year containing a new bootleg and concluding xiv days later with the Latern festival. Years rotate in accordance with both a 12-year cycle of animal zodiacs and a 10-year cycle of ethereal stems, in addition to bi-annual rotating stems. The animal zodiacs are comprised of the rat, ox, tiger, rabbit, dragon, snake, horse, sheep, monkey, rooster, dog and pig. The elements consist of Wood, Fire, Earth, Metal and Water and the heavenly stems are ying and yang. This means that depending on the date, the new year sham the name of an animal, a particular element and is categorized as ying or yang. Within the context of Chinese culture and religious belief, the nature of a year determines ones fortunes, depending on whether or not it is in harmony with ones birth year (K i, 2005).As earlier noted, the Chinese new year unfolds over a fourteen day period, calculated by some as fifteen since preparations commence on the day before.

Engineering - Essay Examplediscussion is to study the development of a control system finished the designed schedule autopilot that enables the flying of a model at different promote conditions in the air.Aircraft have been designed by different parameters and analysis is needed to frame their effects on the performance of the vehicle. The Wright brothers apply the slue tunnel to study the performance of various types of airfoils. There have been advanced wind tunnels that atomic number 18 social occasiond to determine the characteristics of full scale aircraft. On the other hand, use of the wind tunnel in determining flight characteristics and performance of full scale aircraft trunk an expensive exercise and time consuming proposition.Due to advancement in information systems and technology, high speed computing helps determine flight performance of aircraft designs through the use of virtual tunnels. This process involves a computer generated model that is plugged in a Com putational Fluid Dynamics (CFD) program that determines flow characteristics. The results obtained are compared to those found from the real wind tunnel test and the real aircraft performance in flight. However, several studies have been conducted to demonstrate validity and efficacy of the virtual wind tunnel.In this discussion, the two processes are introduced during undergraduate Aircraft Design class. Scale models of different types of aircraft such as the trainer, transport, fighter, and UAV are studied. The scaled models are installed in low speed cross-section wind tunnel used to establish the lift and drag coefficients and pressure profiles. Design of a virtual model of the corresponding aircraft by use of SolidWorks is also done. The virtual models developed are imported to the SolidWorks arise Simulation software. The low speed virtual wind tunnel is simulated in Flow Simulation to establish lift and drag coefficients as pressure profiles are established for various aircr aft at different angles of pitch, yaw, as well as roll.

Information System Analysis of Developing Parking Systems - Assignment ExampleThis melodic theme illustrates that management tuition has been used to remedy set systems in most many corporations. The principles of Management Information Systems in relation to car parking is to arrest efficient car park systems. There is a current parking problem at MUN and it is affecting the operations of the organization. The parking spaces are assigned to particularized individuals and they cannot be used by any other individuals. Furthermore, if the individuals are not avail up to(p) his or her parking slot cannot be accessed. The organization is looking for an good for you(p) parking system that will be used to address the current parking crisis. Management will help develop a method to improve transportation in the enterprise. On the other hand, intelligent car parking has been successfully used to reduce congestion near car parking areas. The parking area will help students and staff me mbers at MUN. It will increase the range of parking convenience and vehicle security in the institution. The individuals at the capability will be able to share their parking in the institution. This will allow them to take advantage of the different peak periods. Students will be able to park once and do their activities efficiently. The parking area will control by a barrier at both the entrance and the exit. The barriers will concur CCTVs installed on them that capture the occupants of the vehicle. Vehicles will be issued with parking tickets that allow shows the time of entrance. Individuals will use the ticket to pay for the parking online or manually. Wireless sensing element networks are used globally to collect and monitor information for the purpose of decision making. They can be used in different environments to monitor information for car parking. The sensing elements are low cost and are deployed in a car park field whereby each parking lot has a sensor node. The se nsor node monitors the activities of the car park slot and sends a message to a database. The database is accessible by the upper layer management system that analyzes the information.

Plato Knowledge Essay Example for Free

Plato Knowledge EssayAristotles Posterior Analytics Reading Questions (1) In the Meno, Plato argued that it was impossible for us to learn something genuinely impertinently if you know x, you dealnt inquire about x, and if you dont know x, you wont recognize it when you find it. Thus, Plato argued, all told learning is really recollection. Aristotle is act to give a different answer to the Meno problem, one that doesnt involve reincarnating or Platonic Forms. What is it? Aristotle argues that knowledge must be displayed in the demonstrative construction of a science. (2) How and why does Aristotle distinguish things former and get around cognise to us from things prior and better known by temper? He distinguishes things prior and better known to us from things prior and better known by nature in Posterior Analytics. What is better known to us versus what is known by nature is not the same thing because what is known to us is affected by our comprehension. Whereas we h ave what is prior and better known by nature which is furthest from perception (particular vs universal is how he describes such.He proves we will result in Platos theory in the Meno of confirming what we already know or learning zilch at all if we fail to distinguish between the two. (3) Why does Aristotle deny that everything rotter be demonstrated? Aristotle denies that not everything can be demonstrated. Those of which whom allow peak demonstration (i. e If A, then B, then A must equal C. ) are reiterating that in conclusion, A is A at all times. This method can be used to prove anything because we are not considering the distinctive properties of each factor.Also, concluding that the results are not deduction nor relevant to the things assumed. (4) Can you explain Aristotles claim that perception produces the universal in us? How does this explain how something indemonstrable can be known? Aristotle claims that perception produces the universal in us it describes that we hav e prior knowledge of a subject that is a commonly accepted idea until one of the factors from that subject proves otherwise. It is not to say that because one takes a stand that all others will do as well but through reasoning we can come to a paradigm shift that accepts the new theory.It would not need to be demonstrated then but simply understood and accepted amongst the community. (5) Plato would agree with Aristotle that we can know x in virtue of having demonstrated that x. further he would disagree with Aristotles account of how indemonstrable can be known. Why, and what would he say instead? Plato would disagree with Aristotles account of how indemonstrable can be known because where he understood universals as forms, Aristotle believes universals are generalizations from particulars.

Analysis of Brick cleaner Aim Essay Example for Free

Analysis of Brick spotless Aim EssayTheory/Hypothesis The main agent in brick cleaner is HCL and must be diluted and titrated with a base to be able to analyse it. It reacts with parts of the concrete which allows it to remove the concrete from the bricks. I think there will be around 30% of HCL in brick cleaner.Materials5mL brick cleaner100mL, 0.1M basisard sodium carbonate solution250ml de-ionised pissing supplyMethyl chromatic indicator250mL volumetric flask4x100mL conical flasksSmall funnel10mL step cylinder* 20mL pipette* Pipette filter* Dropping pipette* burette and standWhite tileElectronic balanceSafety glassesGlovesMethod1) A 250 mL volumetric flask was weighed with its mass recorded2) A 10mL measuring cylinder was used to pour 5mL brick cleaner into the volumetric flask. The flask was stoppered straight after all the brick cleaner was in the flask.3) The flask was then reweighed4) De-ionised water was added until the flask was about half full. The flask was sto ppered and shaken carefully upside down several times.5) More water was added to the flask about a cm below the graduation line. A dropper was used to accurately drop the right amount of water to the flask so the bottom of the meniscus was on the graduation line.6) A 20mL pipette was used to put 20mL of sodium carbonate solution into each of the four 100mL conical flask. 3 drops of methyl orange indicator was added to each.7) The burette was filled with the solution of brick cleaner.8) The sodium carbonate solution was titrated with the solution of brick cleaner until there was a clear permanent colour change.9) locomote 7 and 8 were repeated until 3 concordant results wereResultsWeightVolumetric flask78.968gBrick cleaner6.00gTitre123Initial vol2.323.43.0 last-place vol23.444.524.0Vol added21.121.121.0CalculationsOn page attached.DiscussionThe weight for the brick cleaner may not be 6.00g as the volumetric flask was not weighed again with the brick cleaner in it because that step w as forgotten. So the result above was taken from another student that did the prac. This will affect the results as the mass of the brick cleaner is used to determine the plowshare by mass of HCL in brick cleaner.All 3 titres show that they are only within 0.1 of each other. The hypothesis has been disproved because it was suggested the 30% of HCL would be in brick cleaner and theres only 2.4% although its not certain that those steps were done correctly. There were no problems encountered during this prac.Focus Questions8)a) the manufacturer says that brick cleaner is made up of around 35% HCL, which is a massive difference to the answer that was got in this prac but again question 7 was not done correctly.b) differences in class results occur because not everybody would drive home done the exact volume of brick cleaner, sodium carbonate etc as each other therefore the difference in results obtained.9) To correctly clean up a spill of 20mL brick cleaner you would mop it up immedi ately, washing it away with massive amounts of water10)a) volumetric flask= once with water twice with brick cleanerb) Burette= once with water twice with diluted solution of brick cleanerc)pipette= once with water twice with diluted brick cleanerd) conical flask=once with water twice with sodium carbonate solutionConclusion To conclude, there should be 35% HCL in brick cleaner although it was found that there was only 2.4%.

The Civil Rights Act of 1964 Essay Example for Free

The Civil Rights Act of 1964 EssayPresident Lyndon B. Johnson signed the Civil Rights Act of 1964 into uprightness on July 2, 1964 in Washington D.C. It ended discrimination based on race, color, and religion. Since Reconstruction, it is often called the most important U.S. truth on civil rights. This law allowed the federal official government with the powers to enforce desegregation. Title VI of the act banned the use of federal funds for segregated programs and schools. In 1964 only Tennessee and Texas had more than two per centum of their black students enrolled in integrated schools. About 6% of the black students in the South were in integrated schools by the next year be shit of Title VI.What was the cause of the Civil Rights Act of 1964? In June 1963, President John F. Kennedy proposed a bill several months prior to his death. President Johnson announced his intention to turn the proposal into law five days after Kennedys assassination.Title IV of the Civil Rights Act s of 1964 forbidden discrimination in public schools because of race, color, religion, gender, or national origin. Public schools include elementary, secondary, and public colleges and universities. Before this law was signed, an African-American named throng Meredith applied to the University of Mississippi in 1961. Officials at the school returned his application. He then took his case to the court. On family 10, 1962, the U.S. Supreme Court administrated that he had the right to attend the University of Mississippi. Ross Barnett, the governor of Mississippi, personally blocked Mr. Meredith from registering at the university even after the Supreme Court ruled. Conclusively, on folk 30, 1962, federal officers and Civil Rights Division lawyers led Mr. Meredith onto the campus.There were one hundred twenty three assistant federal officers, three hundred sixteen U.S. modeling Patrolmen, and ninety-seven federal prison guards on and near the campus to guard him. A crowd attacked the federal forces within an hour. They were fought with guns, bricks, bottles, and Molotov cocktails. President Kennedy sent sixteen universal gravitational constant federal troops to the campus because of the nonstop violence. The outcome was there were two people dead, twenty-eight officers were shot, andone hundred sixty people injured. As a result, James Meredith became he first black student to attend the University of Mississippi.The Civil Rights Act of 1964 had many effects. The law outlawed ethnic discrimination in public and places of use of goods and services to African Americans. However, it did not end the Civil Rights Movement. Black Southerners were deprived of their constitutional rights because white Southerners still used legal ways to take away their rights. African Americans lived in the worst metropolitan neighborhoods and had to attend the worst city schools. Other than that, the rights included rights to vote, public accommodations, which included being able to go to restaurants, movie theaters, shop in all stores, going inside a gas station, and attending sports events at sports arenas. The Civil Rights of 1964 was also the first law to guarantee the equal rights of women.
