Part 4.5
An integrator amplifier is a circuit which output voltage proportional to the time integrator of the input voltage. As the name implies, the function of integrator amplifier is configure to perform the mathematical calculus, integration. Integration is the process to find the area under the graph. Hence integrator amplifier, the output voltage it designed to work responds to the input voltage respect to the time.
By applying KCL
The integrator also always has a phase shift of +90⁰ to the output voltage. In which, the input voltage of a sine wave will be outputted with a cosine wave and vice versa. The interchanging of capacitor, Cf and resistance, R1 will become a differentiator circuit.
∅= +90°-tan-1(2πRC)
As an ideal cases, there are no current can flow into the op-amp. This is due to the grounding at the non-inverting terminal and result in the 0V in the inverting terminal. During the experiment, one of the procedures is to use the dc offset to make sure no dc voltage is in Vin. This is because the input offset voltage is not zero or another word, the supplied voltage work together with AC and DC. Hence, the dc input voltage will be integrated and the output voltage starts to drift.

Part 4.6
An op-amp without a feedback resistance is original a difference amplifier. The difference op-amp produces the algebraic difference between the two input signals. Few cases can be done in the difference op-amp. Example like the two input voltage have the same magnitude and the output voltage will be zero which will be the most common. There are no amplification take places when all the external resistors value is the same. Hence, the amplification of the difference op-amp is depends on the ratio of the resistor value.

The output voltage equation can be derived using super position theorem and voltage…...

For a global company with different suppliers, a well-defined process design can mean the difference between profit and loss. A flowchart gives a simplified, easy to understand overview of the processes. From this every step can be analyzed to determine possible improvements in the process design. The flowchart For this flowchart (attachment 1), the control chip (component A) will be supplied by China, the rolling transmitter (component B) by Japan, the plastic housing (component C), by Taiwan, and the key ring (component D), by India. Using standard flowchart symbols, as described by Chase, Jacobs & Aquilano (2006), a waiting area, as depicted by the inverted triangle, will be receiving all parts ordered, to be present before assembly of the keyless entry fob can begin. This can also act as a buffer zone for parts, to minimize the negative effects of poor supply by the manufacturer. Factors affecting the process design. Different factors that may affect the design process could be the supply time by different suppliers, and the on-hand quantity of each of the different components. If a specific supplier cannot deliver a component timeously, vendors need to be changed, or a larger buffer time period may need to be introduced......

...Bottlenecks in a Process Johnson OPS/571 March 17, 2013 Bottlenecks in a Process Information gathered during week one of class was helpful in identifying bottlenecks on the process. Recognizing the bottlenecks that will hinder an individual from achieving daily goals can be a tool to identify ways to manage time better. The Goldratt’s theory of constraint is a dependable theory to identify and successfully handle bottlenecks. Identify Bottlenecks in the Process According to "Theory of Constraints" (2013), “TOC is systemic and strives to identify constraints to system success and to effect the changes necessary to remove them” (Theory of Constraints). The purpose of the process is to manage time wiser so daily goals will be achieved. When time is not manageable an individual will believe there is not enough time within a day to accomplish tasks. The bottlenecks that will hinder accomplishing daily goals would be watching television too much, spending too much time on curricular activities, not creating a “To Do” list, lack of sleep, and exercise. The main bottleneck is not using time wisely to accomplish daily goals successfully. In the Goldratt’s theory of constraints, logical thinking process is one way to help individuals to deal with bottlenecks in a process. According to "Theory of Constraints" (2013), “the thinking process assists with working through the change process by identifying the following: what to change, what to change to, and how to......

The customer will place a food order with a resource working for the company, the chef will prepare the meal, and the server will serve the customers the food. In fast food restaurants, the organization prepares and serves from a little different. The customer still picks an item from the menu, but the customer service representative will take the order and give the food to the customer (Jacobs & Chase, 2010, Chapter 16). These types of companies us a chase strategy, which continuously matches capacity with changing levels of demand. The chase strategy has its advantages, but it also has many challenges, which can cause an organization and its workers grief. Some of the companies that Team D identified as using the chase strategy are Applebee’s, McDonalds and Ford. The following paper will discuss the chase strategy, why these organizations would use it, and the challenges the companies could experience using the strategy. The Chase Strategy The chase strategy requires a business owner to have enough trained employees to take orders, prepare the products for consumption, and deliver the food. In addition, the resources need to know how to run a computer system to charge the...

... Research has shown that unsupervised out-of-school time is associated with various negative youth outcomes such as diminished academic and behavioral functioning and involvement in risky behaviors, including criminal behavior and substance use. And still, low income communities face numerous barriers to access meaningful afterschool programs. After all, the out-of-school alternative private lessons are often not of fordable for many parents in low income communities. To add insult to injury, the public schools have removed a substantial number of arts program from its curriculum, leaving many urban youths disengaged with the community. When urban the youth is exposed to some form of the arts it is usually related to a meager arts & crafts program, which they deem uninteresting. Sadly, by the time they become full fledge teens, they tend to shy away from the arts, and what they associate it with. The argument is that they should be exposed to effective and appropriate arts at a much younger age. Studies show that such exposure earlier on in life, helps them to identify areas of strengths which they can explore later on. On the other hand there is the matter of limited supply or access, which must be addressed. This is not a simple solution of "if you build it they will come" . After all, it is imperative at this juncture in the game, we ask ourselves, is it a matter of just supply in term of programs, funding, and staffing? It is not that simple, and we as......

Birth of Op-Amp

...we know them too. One circuit type that most people today have in their homes and not know about are what’s Operational Amplifiers or op-amps.. You can find them in the amplifiers in our home theater systems or simple TVs or in our transportation like airplanes and automobiles. The op-amp common used in radios or communication devices amplifies the voltage that flows in the differential input out of the single output thousands and thousands of times than the initial input which is why it’s the key component of amplification. This key function is why hooking up a car amp to a set of subs at one end and the head unit at the other gives you that loud booming bass that the young generation loves to have. The op-amp had its earliest begins in the 20th century by J.A.Fleming in 1904 which was a vacuum based rectifier. Used also in analog computers for solving mathematic equations it wasn’t until the 1920s when Bells Lab invented the feedback amp for the telephone. Used a lot in WWII these style of vacuum tubes were then starting to be replaced around the 1950s and 60s because they were large hot and required a lot of power. As technology improved so did the op-amp over the years there has been many different types of amps like IC op-amp, reactor bridge op-amp designed to have very small input current, or the monolithic op-amp. The op-amp we know of today works in both open and closed loop operations. In a open loop the feed forward and feed back path are not......

But when abused they both get you higher than a kite. Medical Marijuana and opiates are used for pain relief, but are widely used for substance abuse. What is Marijuana? Is it an illegal drug? Or is marijuana a medical breakthrough? The United States Government contradicts itself everyday with this issue. The United States Government allows all states to pass bills if they so choose to, allow medical marijuana to be used as treatment for patients with chronic pain and recreational use. The other states are absolutely against the legalization of medical marijuana, saying “it is immoral”. What is the history behind Marijuana? I am going to take you on a journey ten thousand years ago in ancient civilization. Marijuana also called Cannabis was used for fiber. The humans in this time period also used the hemp seed for food. It was only natural that they discovered the medical properties of the plant. Cannabis was actually used for a list of reasons such as hemorrhoids, insomnia, headaches, pain, and even childbirth. But that was some time ago. In the 1970’s scientist were able to extract the THC from the plant. Thus making a synthetic version of the plant, and calling it Marinol. Marinol was approved from the Government and the FDA to be prescribed to patients. It was used to treat......

The Story of Amp

...The Story of AMP 1 Abstract This case study provides an excellent example of the importance of business strategy. It demonstrates how the correct corporate strategy can provide prosperity for a company while a poor strategy can result in dire consequences. The study also highlights how factors such as company size, economic conditions, competition, and corporate culture influence the development and the ultimate success of the business strategy. AMP Incorporated was used as the basis for this case study. AMP Incorporated is a global company that specializes in electronic and electrical connectors. The company, which was started in 1941, quickly grew into the world’s largest manufacturer of connector and interconnection devices. But in 1998, the company’s stock fell, resulting in a hostile takeover bid by Allied Signal and the eventual purchase of the company by Tyco International. History of AMP Founder of AMP Born in Lincoln, Kansas in 1900, Uncas Aeneus Whitaker grew up in a tiny southwestern town in Missouri. He was named after the hero of James Fenimore Cooper’s classic tale, The Last of the Mohicans. In the fall of 1941, Whitaker would start his quest to live the legacy of a hero by taking over a small firm called Industrial Manufacturers in Elizabeth, New Jersey. Industrial Manufacturers was a producer of solderless electrical terminations for the aircraft and shipbuilding industry. Prior to World War II, terminations of electrical conductors were......
