Differential-Amp Circuits - Lab Report Example From figure 2, the input signal was equal to the output signal (unity amplification), and in the same phase (the non-inverting amplifier); both the upper and lower Op Amps were buffer circuits. The value of output was 19.9V because the Op Amp was not ideal. V1a = V1d = 0.2V; V1b= 0V; V3a = 1.16V; V3b = -0.96V; V3d = 2.12V; Afd = 10.6; Afd % Error = 4.4%; R4 = 0.97kâ„ ¦; R5 = 0.97kâ„ ¦; Average of R5 and R4= 0.97kâ„ ¦; R6 = 9.80kâ„ ¦; R7 = 9.84kâ„ ¦; Average of R7 and R6 = 9.82kâ„ ¦ For better suppression or reduction of common mode gain, there was a potentiometer connected to the LM1458C op amps. The potentiometer maintained output voltage at OV when differential input voltage is not applied. The nulling potentiometer improved common-mode gain of small input voltage by availing even smaller input voltages, V1a=0.2V was suppressed to V3a=1.16V as seen in figure 3. A bridge was made for the generation of two different voltages. There was a difference in between measured and calculated voltages due to tolerance or level of uncertainty. The differential gain was obtained through the connection of bridge to respective inputs of the amplifier. The output voltages at the connected bridge were nearly similar to the unconnected bridge; this is because they are connected to the Op Amp inputs that have input resistance of not less than several hundred kâ„ ¦ (LM1458C has 2Mâ„ ¦); V1a was equal to V1b with voltage of 0.197V which corresponded to output 21.3V. The measured differential gain was 107.878. There was minimal signal picked as observed from the oscilloscope, this was due to drifting and DC offset. This problem was caused by low-frequency DC signal; since DC is zero frequency. We could have constructed a high pass filter with very low cutoff frequency so that the Electro Cardiogram’s signal not to degrade. So both large capacitor of more than 1Â µF and large resistor of more than 1Mâ„ ¦ should have been put in place. The instrumentation

Employee of the Month Essay Example for Free

Employee of the Month Essay Zack Bradley, a box boy at Super Club, a Price Club/Costco/Sam’s Club type store. He’s more than content with his life as a box boy. He lives with his grandmother, hangs out with his buddies in their homemade lounge in the center of the store’s shopping racks, trades away dented goods, and gets along with just about everyone. In fact, there’s only one person Zack can’t seem to get along with: lead cashier Vince Downey (Dax Shepard), the epitome of retail world brown nosing. Vince has been employee of the month at Super Club for seventeen months straight and winning the eighteenth time means big prizes (including a â€Å"newish† Chevy Malibu) and a promotion. Usually that title wouldn’t mean anything to a slacker like Zack, but when the new hot cashier Amy (Jessica Simpson) appears on the scene with rumors that she goes for employee of the month, Zack decides to give Vince some competition. This is, at its heart, an underdog film, which I almost always enjoy to some degree. Zack is constantly trod upon by Vince’s overwhelmingly good luck. Even when Zack and his friends try to get the best of the big suck up, something good happens for the egotistical wonder that allows him to come out ahead. It’s a real testament to the power of positive thinking once you learn that Vince sees his job as a big success (â€Å"why climb a mountain when you can win the land race? † he asks) while Zack knows his job sucks but took it as a way not to hurt anyone after a business failure cost his grandmother her retirement savings; Vince thinks well so he does well, Zack doesn’t. But really it’s a way of making the audience really want Vince to get his comeuppance, and feel a great sense of satisfaction once he begins to. With a cast comprised of stand-up comedians, singer turned actors, and former Ashton Kutcher â€Å"Punk’d† assistants one doesn’t exactly expect Oscar caliber acting from Employee of the Month, however the performances aren’t terrible either. Dane Cook acts as a subdued Ryan Reynolds which is exactly what this role needs. Reynolds’ normal antics would be too much for the tempo of this movie. Jessica Simpson only has the demand of being attractive and an object of desire; a role she fills perfectly, although a few of her lines are still wince-worthy. Dax Shepherd is a bit over the top in the villain role, but it works. The true standout performances come from the supporting comedic roles, filled with actors like Andy Dick, Harland Williams, Brian George, Tim Bagley, and Napoleon Dynamite’s Pedro, Efren Ramirez. With a cast able to capture laughs in just about every direction, the film keeps the audience snickering, if not making them laugh a little louder. Indeed, Employee accomplishes more chuckles with a little subtlety than with its attempts at the big laughs, although there are more than a few of those. Observant audience members will notice just how much the employees of Super Club abuse the store’s merchandise, from using broken products as bargaining chips to having gallon buckets of ice cream and massive bags of chips in their homes. People willing to consider the movie even further will find hilarity in the way the employees of Super Club treat their retail jobs so seriously, as if cleaning up that spill or the speed of a cashier’s pass-through rate really matters. Dane Cook and Dax Shepard may not offer the best underdog comedy this year, and the movie certainly doesn’t stand up to Wedding Crashers (which shared the same producers as the advertisements are more than happy to remind everyone) but it’s still an enjoyable, silly little comedy. Consider it along the same guilty pleasure lines as Jingle All the Way or Dodgeball or a more viewer friendly version of that Steve Carell comedy. It’s good for lighthearted fun, just don’t expect any life changing experience watching two store clerks competing for the grand title of Employee of the Month.

The Civil Rights Movement :: African-American Civil Rights Movement

In the postwar years, the NAACP's legal strategy for civil rights continued to succeed. Led by Thurgood Marshall, the NAACP Legal Defense Fund challenged and overturned many forms of discrimination, but their main thrust was equal educational opportunities. For example, in Sweat v. Painter (1950), the Supreme Court decided that the University of Texas had to integrate its law school. Marshall and the Defense Fund worked with Southern plaintiffs to challenge the Plessy doctrine directly, arguing in effect that separate was inherently unequal. The U.S. Supreme Court heard arguments on five cases that challenged elementary- and secondary-school segregation, and in May 1954 issued its landmark ruling in Brown v. Board of Education that stated that racially segregated education was unconstitutional. White Southerners received the Brown decision first with shock and, in some instances, with expressions of goodwill. By 1955, however, white opposition in the South had grown into massive resistance, a strategy to persuade all whites to resist compliance with the desegregation orders. It was believed that if enough people refused to cooperate with the federal court order, it could not be enforced. Tactics included firing school employees who showed willingness to seek integration, closing public schools rather than desegregating, and boycotting all public education that was integrated.   Ã‚  Ã‚  Ã‚  Ã‚  The White Citizens Council was formed and led opposition to school desegregation allover the South. The Citizens Council called for economic coercion of blacks who favored integrated schools, such as firing them from jobs, and the creation of private, all-white schools. Virtually no schools in the South were desegregated in the first years after the Brown decision. In Virginia one county did indeed close its public schools. In Little Rock, Arkansas, in 1957, Governor Orval Faubus defied a federal court order to admit nine black students to Central High School, and President Dwight Eisenhower sent federal troops to enforce desegregation. The event was covered by the national media, and the fate of the Little Rock Nine, the students attempting to integrate the school, dramatized the seriousness of the school desegregation issue to many Americans. Although not all school desegregation was as dramatic as in Little Rock, the desegregation process did proceed-gradually. Frequently schools were desegregated only in theory, because racially segregated neighborhoods led to segregated schools. To overcome this problem, some school districts in the 1970s tried busing students to schools outside of their neighborhoods. As desegregation progressed, the membership of the Ku Klux Klan (KKK) grew.   Ã‚  Ã‚  Ã‚  Ã‚  The KKK used violence or threats against anyone who was suspected of favoring desegregation or black civil rights. Klan terror, including intimidation and murder, was widespread in the South in the 1950s and 1960s, though Klan

Analysis Of A Christmas Carol Essay

Scrooge doesn’t realise but in being disrespectful to the gentlemen, he is disrespecting God. Because by refusing to share and not making good use of his wealth he is not following the 10 commandments. The third is rudeness. One of Scrooge’s traits is his rudeness towards others in society. One major example is when he is introduced to the carol singer. As he is a miserable person who, probably, detests having to move too fast normally, suddenly to do this obviously shows how much effort is involved to try and scare this young pauper. Plus, it can be said throughout the era of the Victorians, carol singing and other social things of a similar meaning could normally be linked to biblical stories. So in hindsight it could be blasphemy (yet not as a major incident). Plus, it’s just basic rudeness as it states with Scrooge’s manner†¦ â€Å"With an ill will Scrooge†¦ † It means that he is ill mannered and will show no mercy no matter the pain he has caused or the consequences. The final factor in the statement is greed. Scrooge portrays this throughout the story very clearly but there is a plain yet critical bit at the beginning where it involves Belle (his love not to be). â€Å"I believe that you would choose a dowerless girl†¦ I do; and I release you†¦ † Well this single quote portrays a vast amount of greed from Scrooge. For instance it mentions dowerless girl. Now dowerless means a sort of inheritance yet it would be given to Scrooge instead which would make him wealthy without having to actually work and still earn money. However, Belle is not rich nor wealthy (with money but with other factors of her personality) which Scrooge does not find ‘attractive’ as this basically entitles that he’s going to have to work and provide for his ‘family’. So with this incident that has compelled these two, Belle, obviously hurt and tearful, decides that it’s best to halt the relationship and walk away, no matter what the consequences. Scrooge remembers his sister with few, yet fond, memories. â€Å"Always a delicate creature, whom a breath might have withered†¦ but she had a large heart. † Although he didn’t spend much time with her (because his father sent him to boarding school) he loved his sister very much and had quite a close relationship with her. However this does not reflect in how he treats his nephew. ‘ â€Å"She died a woman,† said the ghost, â€Å"and had, as I think, children. † â€Å"One child,† Scrooge returned. â€Å"True,† said the ghost. â€Å"Your nephew! † Scrooge seemed uneasy in his mind, and answered briefly, â€Å"Yes. † After the visits of the three spirits, Scrooge starts to recognise the similarities between his late sister, Fan and her son Fred and therefore starts to treat him with respect. After all Fred is the only family Scrooge has. â€Å"They were not a handsome family; they were not well dressed; their shoes were far from being waterproof; their clothes were scanty†¦ But they were happy, grateful, pleased with one another, and contented with the time. † So, with this, it is apparent towards us, the readers, which even though he’s greeted with this repulsive family embedded with poverty, there is still a glimmer of hope for this enlightening time of season. Furthermore, it is becoming even more recognisable that the spirits have transported his beliefs about matters like these, as he states the obvious, but in a mild way he contradicts himself as he’s going back on his original morals and starts to show some affection and emotion towards these who are worse off than him. Where as in the past (technically all his life) he wouldn’t have fluttered an eyelid†¦ â€Å"If they would rather die†¦ they had better do it, and decrease the surplus population. † At the end of the novel, Scrooge learns how to be polite to others around him. When he passes the two gentlemen, whom he’d been rude to the day before, he asks for forgiveness for his actions. â€Å"That is my name, and I fear it may not be pleasant to you. Allow me to ask your pardon. † Here Scrooge shows that he has changed and that he is proud of his name and the person attached to it. Here he also displays that he is ashamed of the way he acted towards them when they came to collect money for the poor. He also asks for forgiveness for possibly the first time in his life. Scrooge awakens, on Christmas morning, a much happier man. He is delighted to be alive and reminisces the night’s events, which have now compelled him to be a better, more improved, man. â€Å"I am as light as a feather, I am as happy as an angel, I am as merry as a schoolboy, I am as giddy as a drunken man! A merry Christmas to everybody! † He leaps about rapturously not believing his fortune, and is extremely vivacious. Scrooge changed in many ways after the visits from the three spirits. He is now charitable without seeking credit for himself, which is a complete contrast to before when he refused to donate any money to charity and was very rude to the ‘collecting’ gentlemen. An example of this change of character is when Scrooge is buying the turkey for Bob Cratchitts family he says, â€Å"I’ll send it to Bob Cratchitts†¦ He shan’t know who sends it! â€Å"
