...induction motor in order to calculate the parameters, which is almost impossible to obtain a perfect non-linear model. Hence the values of the parameters that are obtained from it are thereby approximate. This leads us to more advanced control methods to meet the real demand. To overcome the complexities of conventional controllers, fuzzy logic controller have been implemented in many motor applications. A Fuzzy Logic Controller (FLC) is incorporated for combination with Phase Locked Loop (PLL) for precise and robust speed of induction motor. The fuzzy logic controller is used to pull the motor speed into the locking range of PLL. When the speed error is between the set point speed and the measured speed is larger than the preset value, the motor speed is incremented or decremented by the fuzzy logic controller towards the PLL locking range. In order to achieve excellent speed regulation, PLL control replaces the FLC when speed error is within the locking range of PLL. When the system operates in the phase locked...

...Thursday, May 07, 2015 1:31 PM This assignment involves solving problems by using various discrete techniques to model the problems at hand. Quite often, these models form the foundations for writing computer programming code that automate the tasks. To carry out these tasks effectively, a working knowledge of sets, relations, graphs, finite automata structures and Grammars is necessary. Part I: Set Theory Look up a roulette wheel diagram. The following sets are defined: •A = the set of red numbers •B = the set of black numbers •C = the set of green numbers •D = the set of even numbers •E = the set of odd numbers •F = {1,2,3,4,5,6,7,8,9,10,11,12} From these, determine each of the following: •A∪B •A∩D •B∩C •C∪E •B∩F •E∩F Part II: Relations, Functions, and Sequences The implementation of the program that runs the game involves testing. One of the necessary tests is to see if the simulated spins are random. Create an n-ary relation, in table form, that depicts possible results of 10 trials of the game.

...Chapter 10 Transaction Management and Concurrency Control Discussion Focus Why does a multi-user database environment give us a special interest in transaction management and concurrency control? Begin by exploring what a transaction is, what its components are, and why it must be managed carefully even in a single-user database environment. Then explain why a multi-user database environment makes transaction management even more critical. Emphasize the following points: • A transaction represents a real-world event such as the sale of a product. • A transaction must be a logical unit of work. That is, no portion of a transaction stands by itself. For example, the product sale has an effect on inventory and, if it is a credit sale, it has an effect on customer balances. • A transaction must take a database from one consistent state to another. Therefore, all parts of a transaction must be executed or the transaction must be aborted. (A consistent state of the database is one in which all data integrity constraints are satisfied.) All transactions have four properties: Atomicity, Consistency, Isolation, and Durability. (These four properties are also known as the ACID test of transactions.) In addition, multiple transactions must conform to the property of serializability. Table IM10.1 provides a good summary of transaction properties. Table IM10.1 Transaction Properties. |Multi-user | |Single-user | |atomicity:...

...Comparing Short Stories: A Rose for Emily and The Yellow Wallpaper Both Emily from Faulkner's A Rose for Emily and the female narrator from Gilman's The Yellow Wallpaper experience extreme internal dramas. The women's internal conflicts cause both characters to lose sight of sanity and react in odd and different ways. These gothic tales both present ideas of women subornation, tradition, and the power of death. Nevertheless, they do so in different ways, and with very different stories. Both stories contain timely examples of women subornation with men overpowering and belittling their counterparts. In The Yellow Wallpaper, the narrator is a prisoner, and simply remains a second class citizen. Treated as a child, locked away in a room, her...

...AIFS’ business of sending students abroad and the timing difference between when the prices were set and when payment was received created transaction exposure. Guaranteeing that prices of the trips would not change prior to the release of the next catalog was a major table stake of the company’s business, and very important to maintaining a loyal customer base. Given this, movements in the cost basis caused by fluctuations in exchange rates could not be passed onto customers. When combined with the fact that there was a relatively long lead time between when prices were locked in and when the payment from students was received (over a year in the college student program) resulted in a significant amount of uncertainty regarding the company’s primary operating cost. The potential variance in the annual volume of students enrolled in the company’s programs also created issues with currency exposure. Hedging based on projected sales totals is difficult, especially when certain events that can materially impact volumes are well beyond the company’s control. If no hedging was done, the company would be fully exposed to the movements in exchange rates after each price was set/catalog was issued. The magnitude and direction of the movements from when the price was locked in would determine the gain or loss on each individual trip that was booked. This would cause the company’s cash flows to be quite volatile, and this uncertainty would create a litany of problems for the company....

...The weaknesses in internal control over cash disbursements at Idaho Company are; 1. Checks are not pre-numbered, 2. More than one person is authorized to issue checks, 3. Unissued checks are not locked in a safe or locked cabinet. My recommendations to improve company procedures for internal control over cash disbursements are; there should only be one specified individual such as a treasurer authorized to sign checks. There should never be two people authorized for check signing. Make sure to assign a different person to each of these tasks; 1. Approving items for payment, 2. Paying the items, 3. Recording the payment. Use pre-numbered checks and accounting for all checks, with each check supported by an approval invoice. Always store blank checks in a safe or a locked cabinet or drawer with restricted access and use a machine to print the amounts on the checks. Compare each check with the approved invoice before issuing the check and make monthly reconciliations of bank and book balances. After payment stamp each approved invoice paid. The principles of internal control are; establishment of responsibility, segregation of duties, documentation procedures, physical, mechanical, and electronic controls, independent internal verification, and other controls. Now that Guard dog company’s checks are pre-numbered and they are using the new check writer these two things fall under Documentation procedures and physical, mechanical and electronic controls.

...CS4321 Project 5: Transaction Processing System November 21, 2012 This project is due on November 29th, at 23:59pm via CMS. It is worth a total of 100 points. It counts for 25% of your grade. Read the whole assignment carefully, and review the relevant textbook materials, before you start implementing. The relevant material for this assignment can be found in Chapter 16 and 17 of the course textbook. The Big Picture Figure 1: A Simple Transaction Processing System 1 Overview In this assignment, you will implement a transaction processing system. The aim of the project is not to design a completely generic transaction processing engine but rather to give you a taste of the design decisions and challenges involved in doing so. You will be implementing transactions which can read, write and update values in a key-value store. As shown in gure , transactions access the key-value data stored in a "data page" through a linear hash index. The hash index in turn uses the bu er manager to fetch the appropriate pages from the disk. We will provide you with a implementation of a linear hash index in the form of a library. Note that as long as the interface for the index is the same, the linear hash index may as well be replaced by a B+-tree index like the one which you implemented in the previous assignment. However, the B+-tree assignment you implemented does not support concurrent modi cation and hence cannot be used here directly. The linear hash index which is provided...

...1. Define why change control management is relevant to security operations in an organization. • Change control is a precision arrangement of managing every change made to a system. This is to ensure that no unneeded changes are done, that every change is documented, and that no service is disrupted unless absolutely necessary, and that all resources efficiently used. 2. What type of access control system uses security labels? • A LBA C Label Base Access Control 3. Describe two options you would enable in a Windows Domain password policy. • Password must meet complexity requirements • Minimum Password length 4. Where would patch management and software updates fall under in security operations and management? • Procedures/ The SA or other personnel to be the responsible authority in informing all local authorities about patches that are related to software packages included on the entire inventory of the organizations software. • • Also in Procedures/ Additionally, any post-patch update distributions to the Database/Management Configuration Plan will be executed immediately after any patching has been done. 5. Is there a setting in your GPO to specify how many logon attempts will lock out an account? Yes, The Account Lockout Threshold can be set, this policy determines the number of failed attempts to logon, before the users’ account becomes locked. Once locked, it can not be...

...complex prison system but is in great need of reform. The michigan Prison system costs tax payers over 2 billion a year and has nearly 47 percent more prisions than other great lake states. The costs of the michigan prison system makes up more than 20 percent of the state budget. The state is in despereate need of reform or change to keep there prison system running. One key promblem in the prison system is the rapid boom in prison population. since 1960 the population in the prisons have grown from 9,000 inmates to over 50,000 inmates. Michigan on avergae keeps prisoners locked up a year longer than other states. Michigan also has more prisoners locked up past there proale date than other states do. What is being done about this promblem, well not alot. Governor Jennifer Grandholm of michigan had promised reform in the prison system. She closed 20 small prison camps which will save the state of michigan over 1 billion dollars over a ten year period. She also spoke about reducing prison population however most michigan inmates served there full sentence or ever longer. On average one inmate costs the state of michigan 33,000 dollars to keep locked up. The solution would seem to be to release inamtes early however this is not an idea the public typically likes. The taxpayers desparatly want lower taxes but do not want criminals on the street. However when Gov. Grandholm closed prison camps the crime acually went...

One of the necessary tests is to see if the simulated spins are random. Create an n-ary relation, in table form, that depicts possible results of 10 trials of the game. Include the following results of the game: * Number * Color * Odd or even (note: 0 and 00 are considered neither even nor odd.) Also include a primary key. What is the value of n in this n-ary relation? The primary key is the trial attempts, the reason for this is because only one attempt can be linked to that trial attempt, therefore making it unique. The value of n is four.

...Number 40 In the story Number 40, it is clear that it is a third person point of view. The narrator talks about the main character as "she" and her by her name. We see that in following quotes, "Melissa hated forgetting things" (p. 1 l. 1) and "She watched raindrops chase each other down the bus window". This is two quotes where the narrator clearly uses third person of the main character. This is something that happens through the whole story, so the point of view doesn't change. Furthermore me can say that it is a limited narrator in some ways, because we don't know how the main characters deep emotions. On the other side we know how she is as a person, that she is forgetful and how she feel about her living fellow Simon, talking to the other girl Emma or Emily, who she clearly had forgot the name of because she is this forgetful. If we look on the setting, I will start give a characterizing of both Melissa and Simon. Melissa is confused and forgetful. She is also a bit jealous on Simons friend Emma or Emily from work. Furthermore you can say that she might be full of fantasy because she suddenly can't find her house or might even live in a fantasy world. On the other hand there is Simon, he is presented as superior, in that way he knows better, and she will always call him if there is something she can't remember, we see that in following quote "But couldn't remember the name. if she'd had her phone she would have called Simon, because he was good at things like that'...
