Paper Towels on Trial essays

Paper Towels on Trial essays Paper Towels On Trial Have you ever wondered what the best brand of paper towels is? Or what "the best" actually means? Well, our group adventured out to find "the best" paper towel! We tested seven different brands of paper towels. We did 3 different controlled experiments to collect data. The data will help to determine the best paper towel out of the seven brands we tested. The brands we tested were: Bounty, Scott, Viva, Home Best, Strong n' Thirsty, Good Day, and Green Forest. The materials we used for our controlled experiments included: a tub(to hold water), a dropper(for the absorbency test), a cup, seven brands of paper towels, a few flasks, a triple beam balance scale, water, our chart(to record the data), our hands(for the absorbancy test), and our groups table. Here are the tests, and our steps we used to obtain the data. 1. Two people hold the paper towel tightly about 6 inches above the table. 2. One person cups their hands underneath the center of the paper towel. 3. One person drops the water onto the paper towel with the dropper. 4. The person dropping water counts how many drops it takes before it drops throught the paper towels. 1. One person soaks a paper towel in water. 2. Another person times, with a watch, the time it takes for the paper towel to rip. 3. One person rubs the paper towel back and forth on the table with their fingertips until it rips. 1. Set the water tub on the table with a little bit of water in it. 2. Two people hold a soaked paper towel tightly over the tub. 3. One person gently sets a flask on top of the paper towel. They fill the flask with water until the paper towel breaks. 4. When it breaks, someone goes and weighs the flask, and we record the weight for the strength test. There was more than one brand that won in the absorbancy test. They were Sc ...

Summary of the Battle of Stamford Bridge

Summary of the Battle of Stamford Bridge The Battle of Stamford Bridge was part of the invasions of Britain following the death of Edward the Confessor in 1066 and was fought September 25, 1066. English Army Harold Godwinson7,000 men Norwegian Army Harald HardradaTostig Godwinson7,500 men Battle of Stamford Bridge Following the death of King Edward the Confessor in 1066, succession to the English throne fell into dispute. Accepting the crown from the English nobles, Harold Godwinson became king on January 5, 1066. This was immediately challenged by William of Normandy and Harald Hardrada of Norway. As both claimants began building invasion fleets, Harold assembled his army on the south coast with the hope that his northern nobles could repel Hardrada. In Normandy, Williams fleet gathered, but was unable to depart St. Valà ©ry sur Somme due to adverse winds. In early September, with supplies low and his troops obligations expiring, Harold was forced to disband his army. Shortly thereafter, Hardradas forces began landing at Tyne. Aided by Harolds brother, Tostig, Hardrada sacked Scarborough and sailed up the Ouse and Humber Rivers. Leaving his ships and part of his army at Riccall, Hardrada marched on York and met the Earls Edwin of Mercia and Morcar of Northumbria in battle at Gate Fulford on September 20. Defeating the English, Hardrada accepted the citys surrender and demanded hostages. The date for the surrender and hostage transfer was set for September 25 at Stamford Bridge, just east of York. To the south, Harold received news of the Viking landing and attacks. Racing north, he gathered a new army and arrived at Tadcaster on the 24th, after marching nearly 200 miles in four days. The next day, he advanced through York to Stamford Bridge. The English arrival caught the Vikings by surprise as Hardrada had expected Harold to stay in the south to confront William. As a result, his forces were not prepared for battle and much of their armor had been sent back to their ships. Approaching Stamford Bridge, Harolds army moved into position. Before the battle commenced, Harold offered his brother the title of earl of Northumbria if he would desert. Tostig then asked what Hardrada would receive if he withdrew. Harolds reply was that since Hardrada was a tall man he could have seven feet of English earth. With neither side willing to yield, the English advanced and began the battle. The Viking outposts on the west bank of the River Derwent fought a rearguard action to allow the rest of the army to prepare. During this fight, legend refers to a single Viking berserker who single-handedly defended Stamford Bridge against all odds until stabbed from below the span by a long spear. Though overwhelmed, the rearguard provided Hardrada time to assemble his forces into a line. In addition, he dispatched a runner to summon the rest of his army, led by Eyestein Orre, from Riccall. Pushing across the bridge, Harolds army reformed and charged the Viking line. A prolonged melee ensued with Hardrada falling after being struck by an arrow. With Hardrada slain, Tostig continued the fight and was aided by Orres reinforcements. As sunset approached, both Tostig and Orre were killed. Lacking a leader the Viking ranks began to waver, and they fled back to their ships.   Aftermath and Impact of the  Battle of Stamford Bridge While exact casualties for the Battle of Stamford Bridge are not known, reports suggest that Harolds army suffered a large number of killed and wounded and that Hardradas was nearly destroyed. Of the approximately 200 ships the Vikings arrived with, only around 25 were needed to return the survivors to Norway. While Harold had won a stunning victory in the north, the situation in the south was deteriorating as William began landing his forces in Sussex on September 28. Marching his men south, Harolds depleted army met William at the Battle of Hastings on October 14. In the battle, Harold was killed and his army defeated, opening the way for the Norman conquest of England.

History 3 - Essay Example Despite enjoying all these earthly pleasures, the merchants and samurai who enjoyed the floating world felt that their lives were meaningless. The floating world came about due to the emphasis on formal education, literature and philosophy. The participants of the floating world culture included, sumo wrestlers, theater actors, prostitutes, geisha the samurai and the wealthy merchants. The more people were more knowledgeable after going through formal education, their social lives mainly revolved around the floating world. Tokugawa Leyasu assumed power after he was able to defeat the Hideyori (the son of Hideyoshi) loyalist and some of his other western rivals in the battle of Sekigahara in 1600 (Bentley & Ziegler 2011). This is after Hideyoshi had died in the year 1598. In the year 1603 Tokugawa Leyasu was appointed shogun by the then emperor. In the year 1615 Tokugawa Leyasu captured the Osaka castle. By capturing the Osaka castle this meant that he had no more rivals. Immediately after assuming power in 1600, Tokugawa Leyasu distributed gained land to the daimyo. Leyasu put in place a law that required the daimyo to spend every second year in Edo. Through these strategies the shoguns were able to control the daimyo as this made sure that daimyo were not financially stable. Tokugawa Leyasu promoted foreign trade with the English and the Dutch. However, Leyasu forbade the locals from travelling and abroad. This isolated japan from the rest of the world. During this time domestic trade and agriculture greatly improved. Another factor that led to the economic and population growth under the shoguns period was peace. Tokugawa was able to take control of warring states. Political stability also led to economic and population growth. The Qing dynasty ruled the Chinese empire from 1964 to 1912 (Bentley & Ziegler 2011). The Qing dynasty rose into power after the fall of the Ming dynasty. With the help of General Wu Sangui

Furthermore, for configuring multiple operating system environments on active directory, a domain server must be placed in Georgia, India, California, Canada and New York. As all applications are hosted on the Phoenix site, they should be configured on HTTPS and must use a VPN tunnel for exchanging data with the other 4 sites. Moreover, for adding an extra layer of security, MAC addresses should be linked with WAN IP addresses requesting access to one of the hosted applications. Access Control policy should be drafted that will address access to whom and why. A responsible, Accountable, Consulted and Informed (RACI) chart should be developed, as it will define roles and responsibilities for each user permitted to access web based applications. 2 Blowfish Encryption Algorithm for NextGuard As per computer desktop encyclopedia Blowfish encryption algorithm is defined as â€Å"A secret key cryptography method that uses a variable length key from 32 to 448 bits long. It uses the block cipher method, which breaks the text into 64-bit blocks before encrypting them. Written by Bruce Schneier, as a free replacement for DES or IDEA, it is considered very fast and secure† and as per network dictionary, it is defined as â€Å"Blow?sh is an encryption algorithm that can be used as a replacement for the DES or IDEA algorithms. It is a symmetric (that is, a secret or private key) block cipher that uses a variable-length key, from 32 bits to 448 bits, making it useful for both domestic and exportable use†. Blowfish is an encryption algorithm that was invented by Bruce Schneier in 1993 (Pachghare, 2009). It is constructed on a variable length key ranging from 32 buts to 448 bits that is considered to be perfect for both local and international use along with a solid enc ryption algorithm. After its recognition to be relatively solid encryption algorithm, it is gradually gaining acceptance. Some of the core features of blowfish algorithm include (Pachghare, 2009): Blowfish has a block cipher of block consisted of 64 bit The length of the key can be up to 448 bits BladeCenter web interface: MM Control, Login Profiles page. (n.d.) On 32 bit microprocessor architecture, data encryption is supported at a rate of 18 clock cycles on every byte that is much quicker than DES and IDEA encryption. It is still free to use and is not patented Memory requirements for blowfish are less than 5 kilobytes of memory The semantics are simplified and is relatively easy to deploy The design requirements for a blowfish encryption algorithm incorporates robust, simple to code, compact, easily modifiable and flat key space features (Anderson, 1994). Likewise, flat key space facilitates random strings to be considered as a possible key from a required length. Moreover, it d eploys data in massive byte size blocks and incorporates 32 bits blocks where applicable (Anderson, 1994). Key ranges, as mentioned earlier are from 32 to 448 bits and operations are common that are supported by microprocessors such as XOR, table lookup etc. furthermore, pre-computable sub keys are applicable with variable iterative numbers. These sub keys are massive and must be pre-calculated prior to encryption or decryption process carries out. In an example below, let’s assume that P is pre-calculated array consisting of 18, 32 bit sub keys from P1, P2†¦ till P 18. In addition, there are S boxes (32 Bit) indicated by S with entries equal to 256 each (John Rittinghouse & Hancock, 2003). S1, 0, S1, 1†¦S1, 255; S2, 0, S2, 1†¦.S2, 255; S3, 0, S3, 1†¦

Wk 1 Case Study Essay Example for Free

Wk 1 Case Study Essay Economic development in the midsouth did not always have reliable access to transportation. This was devastative because much of their growth depended heavily on transportation. Midsouth Chamber of Commerce, MSCC, was formed by a group of legislators who wanted to push for more access to transportation. Midsouth Chamber of Commerce started off strong. They were an aggressive advocacy for their business community. Their growth over the years helped them turn their organization into a business, hitting the million dollar mark. It wasn’t long, however, before their growth took a turn. The company relied heavily on the sales and marketing functions. MSCC lost many contracts with corporations because they could not keep up with the wide spread use of the internet. That was when MSCC decided to hire Leon Lassiter to take control of their sales and marketing functions. Leon Lassiter joined the MSCC in the year 2000. According to the case study â€Å"Midsouth Chamber of Commerce (A): The Role of the Operating Manager in Information Systems† Lassiter’s first task when joining the team was to review all of the programs, processes, and procedures of the company (par. 9). Right away he noticed that the information system was so  limited no one had access to do anything but the limited amount required by their job function. â€Å"No staff member had access to all the data necessary to operate the marketing and sales activities† (par. 9). Processes were done in steps starting from the lowest job level and then working its way to the top. To get one data request it would take approximately three days. Lassiter began to work with Wilson who was in charge of the operations division at MSCC. Though they did not agree with each other’s proposed plans for how the financial division should run, they both agreed to control costs. As time passed, the information systems of the company Kissell 3 grew. This brought necessary organizational changes. Staff changes were made to fall in line with the informational upgrades throughout the company. When this happened, the concern for top management arose. Lassiter and Wilson agreed that they would invest in the new information system created by a former consultant named Kovecki. Management and staff took well to the new work station arrangements. The new system, UNITRAK, helped reduce the costs of software. Unfortunately, this did not last long. They system continued to need upgrading and was never able to be implemented into the business. Lassiter continued to see disappointment with the UNITRAK. The time spent training employees on the system cost thousands of dollars, just for the materials to be forgotten. This case outlines the importance of a business and its technology. A company should always be prepared for change. MSCC did not seem like they were readily able to adapt to the change in information systems. The current situation is that the company is losing money each day the new software is not implemented. Kovecki is currently looking for a new job, but was hired by MSCC to build the companies new information system. In the future if MSCC continued to wait on Kovecki’s information system, money would be wasted. He was given months to provide MSCC with a process that worked, but has only been breaking down and not staying up to date. With the rate that MSCC is losing clients and money, waiting on Kovecki would be a mistake. He is clearly looking for a new job which implies that he has no interest in helping MSCC. It would he highly recommended that Lassiter and Wilson review their contract with Kovecki. If Kovecki does not complete the requested upgrade of the information software, they Kissell 4  will need to terminate working with Kovecki and look to a new informational software. MSCC was not prepared for the wide use of the internet. They used old processed from the time they originated which caused them to lose money. Although it was costly to implement a new information software, Lassiter was looking toward the best interest of MSCC’s future.

Benifits Of Technology Essay -- essays research papers

Man, powered by his imagination and inquisitive character, has wondered he mechanisms of Nature since time infinite. This quest for the truth, the ways in which his surrounding works, has led to many a scientific discoveries and innovations. Since the art of making fire and creating handcrafted tools, our civilization has come a long way. Science and Technology are making advances at an amazing rate. From telephones to the Internet, calculators to computers, cars to rockets and satellites, we are submerged in a sea of discoveries and inventions made possible by Science. Fields like Medicine and communications have made inroads into our cultures and thus our lifestyles. So vast is the impact of Science in our lives, that people fear the unthinkable. It leads them to accusations such as Science tries to play God. However, according to Hume, God is part of the order that exists in the universe. If so, then Science is just helping us discover the Almighty, which most people perceive as the Ultimate Truth. To quote Charles Pierce, ""There is one thing even more vital to science than intelligent methods; and that is, the sincere desire to find out the truth, whatever it may be." Repeatedly, it is also heard that we are so dependent on Science and Technology that we who create it are nothing but mere puppets. How can we be the slaves of this great resource? In fact, it would not be wrong to term Science as a friend of Humanity. This faithful friend has come through many a times. We have reaped innumerable benefits out of this friendship. In return, the sacrifices we had to make constituted just a small price in return. This price can be termed as a small token of appreciation for our friend, Science. According to an existential argument, existence precedes essence. If so, then human existence is absurd and unjustified. The goal of a human being then is to justify his existence. We humans tried to take charge of our own lives by choosing to justify its cause. According to Mahlotra, a person who is aware of the fact that by the freedom of choice we have, we are responsible for our actions and performs those actions acknowledging freedom of others too, is the one who shall find meaning in his life. Satre points out for us that a man is nothing else than a series of undertakings, that he is a sum, the organization, the ensemble of the relationsh... ... thus shrink of a thought of war on an enemy. In my opinion, Technology and Science like most things have both the good and the bad side to it. There are definitely certain ethical and legal issues associated with it. However, looking more closely at our world, we find ethics in most of the disciplines including Religion. People can take advantage of any field if they wish to, but our social and political ties prevent most of us from acting in manners considered as taboos. Some people who yet work in ways to disrupt the social structure are often times rejected. Further there are laws in place to guarantee that no one’s right to freedom of choice is infringed upon. Douglas Shrader tries to explain through the Utilitarianism Principle that if an act produces more good than harms for a society, it can be reasoned out as a right thing to do for the society as a whole. Similarly, if we take a balance and weigh the benefits and costs of Science and Technology, we would find that the case is not even close. The benefits far outweigh any costs connected with Technology and Science. In fact, it seems almost impossible now to imagine a world living without its Science and Technology.
