Reflection Questions Assignment Example | Topics and Well Written Essays - 250 words

Reflection Questions - Assignment Example These weapons were devastating to soldiers as death tolls during the Great War’s massive battles resulted to horrific loss of life due to these new weapons. Civilian populations were mobilized to many industrial factories as these weapons were needed to be manufactured at both high rate and volume. While Russia’s initial involvement in the Great War was seen in a positive light, most Russian soldiers were conscripts who were not close to willing to join in. Coupled by the lack of effective logistics, poor leadership of Russia’s many officers, and the eventual staggering casualties and desertions; it would be no surprise that such news would increase the discontent in the already disillusioned Russian population to the point of revolt. As Trotsky (1930) observed, â€Å"the revolutionary elements, scattered at first, were drowned in the army almost without a trace, but with the growth of the general discontent they rose to the surface† (p.15). The withdrawal of Russia would lead to military and political changes in Europe afterwards. Howard (2002) posited that â€Å"by then the Russians might well be out of the war and the Germans able to concentrate all their forces on breaking the Western allies†, this would add military pressure to the Western Front which France and Great Britain were engaged in. Politically, Russia’s humiliating withdrawal would lead to the downfall of the Tsarist regime and pave way for the rise of the Communist Soviet Russia. The Russian Provisional Government under the Kerensky administration insisted on remaining in the Great War in was to adhere to its obligations with Russia’s wartime allies to continue the fight against the German and Austro-Hungarian Empires. This did not make the soldiers feel any better since such an objective showed less concern for the country’s welfare and situation. Vladimir â€Å"Lenin† Ulyanov and Lev Bronshtein,

Assignment 6 Essay Example | Topics and Well Written Essays - 1750 words

Assignment 6 - Essay Example We look to interpret that change in behavior and form an analysis based on our reading. For so many years that humans have evolved, they have become masters in reading their fellow beings behavior (Norman, 2004). We definitely need to take people’s feelings seriously especially as a producer or designer. A producer must keep in mind his consumers when producing something. If the product is well designed and everything works as expected from the product, then there will be a positive response coming out of consumers. They might add it as part of their daily, weekly or monthly purchase depending upon its usage and durability. On the other hand, if a product turns out to be undesirable or not what it promised, then there is a high possibility that the consumers might take out their frustration on it. It is very easy to blame the product if it does not meet out the requirement so the designer must consider people’s feeling before putting his heart and soul solely on the pro duct (Norman, 2004). Norman is of the opinion that machines in the future will need social interaction and a network of communication to get the job done. He is of course not kidding and why would he if he thinks that machines can perform faster and better with interaction among themselves. If they could be programmed to coordinate like human beings, then I think machines can do a better job simply because they do not fatigue out. They can continuously work for longer hours without any rest. To be honest, they do not even need lunch and tea breaks. It is a very good idea to make them work independently, without humans operating them. More and more machines and robots are being deployed to work in organizations, and it would be so much easier if these robots are made to communicate without a helping hand from us. Robots are now being used in dangerous jobs like fire fighting and in military for war purposes. Apart from this they are also used for house cleaning, delivering letters an d washing cars. Their role is expanding and to make way for them we need to program them with emotions. We need to make them wary of what basic emotions like pain are. We would not want to see them bumping to cars or people every now and then if we want to introduce them freely in this world. When they know what pain is they will automatically look to avoid smashing into things for their and our sake. I totally agree with Norman when he says that we could slowly distribute or install emotions in them. It is going to be a step by step process; for example, in the initial stage they could be taught what fear, satisfaction after achieving a certain goal, consistency in maintaining their work and obedience to their owners. Emotional interaction with robots will also give us an opportunity to know them better. We could penetrate if they are happy with their work or not, making progress or having difficulties. Then we could treat them according to their mood. We could also know what motiv ates them and reward them to work better and faster. There is so much room for improvement and with the pace science is making progress I believe one day robots will be a household name. The sooner we plan the better it is (Norman, 2004) 2. Witthower has been exemplary in his work on the iPod and the iPod’s implications. It looks like he has not missed a single point on the subject. It’s not only detailed, but it is also one of the most organized books to read. The book

Global Corporate Strategy Essay Example | Topics and Well Written Essays - 500 words

Global Corporate Strategy - Essay Example In an example, two airline companies might create a strategic alliance through bringing up their resources together to create a strong advertising website in order to develop a more effective marketing process. Strategic alliance is more effective in companies that have closely related products (Vedder, 2008). One of the major differences between strategic alliance and other joint ventures is that the business that forms an alliance remains independent. Alliances involve transfer of technologies, economic specialization and sharing of different expenses and risks. Types of strategic alliances include; Joint ventures, equity strategic alliances and global strategic alliances (Kleymann & Seristà ¶, 2010). Unlike strategic alliances where businesses involved in alliances remain independent, merging involves dissolution of both businesses’ activities to form a single entity. In mergers, businesses combine their transactions and form a single and more powerful business. With increased level of globalization that is being experienced currently, the level of competition has increased tremendously as multinational companies which have a powerful financial base have been able to invest in different countries. Airline industry has been one of the most hit organization an aspect that has made two or more airline industries coming together to form a strong organization (Kumar, 2012). One of the benefits of merging is increased competitiveness of the organization formed due to increased financial resources, technical resources and human resources. In addition, the level of competition between the companies forming a merger makes it easy for the company formed to make effective decision w ithout fear of intense competition. Some of examples of successful mergers include Pan Am and National alliances and Northwest Airline which merged with Delta to form one of the largest airline industry (Hecker, 2009). Acquisitions on the other hand, involve a corporate action by a

Functional Relationship Network Architecture

Functional Relationship Network Architecture A computer network, is referred to as a network, it is a harvest of computers and instruments interconnected via communication channels that enables communications among users and permits users to allocated resources. Networks may be classified according to a wide range of characteristics. A computer network permits sharing of resources and knowledge among interconnected devices. Fig1:Block diagram of computer network Connection method Computer networks can be classified according to the hardware and software engineering that is accustomed to interconnect the individual devices in the network, such as optical fiber, Ethernet, wireless LAN. Functional relationship (network architecture) Computer networks may be classified according to the functional relationships which exist among the elements of the network, e.g., active networking, client-server and peer-to-peer architecture. Network topology Computer networks may be classified according to the network topology upon which the network is grounded, such as bus network, star network, ring network, mesh network. Network topology is the coordination by which tools in the network are organized in their rational family members to one another, independent of physical arrangement. Even if networked computers are physically placed in a linear arrangement and are joined combined to a hub, the network has a star topology, alternatively a bus topology. In this regard the visual and operational aspects of a network are distinct. Networks may be classified grounded on the process of knowledge adapted to carry the data; these include digital and analog networks. Fig2. Mesh topology Fig3. Star Topology Fig4. Ring topology What is a firewall? Fig5. firewall A firewall is a component of a computer system or network that is arranged to avoid unauthorized access where letting agent communications. It is a implement or set of tools that is configured to sanction or turn down network transmissions grounded upon a set of administers and other criteria. Firewalls can be implemented in either hardware or software, or a combination of two. Firewalls are commonly adapted to prevent unauthorized Internet users from accessing private networks joined combined to the Internet, especially intranets. All messages entering or withdrawing the intranet surpass through the firewall, which inspects each outcome and prevents those that do not find the specified protection criteria. There are several types of firewall techniques: Packet filter: Packet filtering checks each packet that is passing through the network and accepts or refuses it based on particular IP addresses that is user defined. Although difficult to configure, it is effective and mostly transparent to its users. It is vulnerable to Internet Protocol spoofing. Fig6. Packet filters This type of packet filtering pays no heed to if a packet is part of an older stream of traffic (i.e. it stores no information on connection state). Instead, it filters each packet based only on information contained in the packet itself . TCP and UDP protocols consists most communication over the net, and because TCP and UDP traffic by convention uses well known ports for some types of traffic, a stateless packet filter can differentiate between, and hence control, those types of traffic (such as web browsing, remote printing, email transmission, file transfer), untill the machines on each side of the packet filter are both using the same non-standard ports. Packet filtering firewalls work mainly on the initial three layers of the OSI reference model, which means most of the work is done in between the network and physical layers, with a little bit of peeking into the transport layer to find out source and destination port numbers. When a packet originates from the sender and filters through a firewall, the device finds matches to any of the packet filtering rules that are configured in the firewall and removes or rejects the packet accordingly. When the packet goes through the firewall, it checks the packet on a protocol/port number basis (GSS). Application gateway: Applies security mechanisms to some applications, such as FTP server. This is effective, but can degrade the performance Fig7.OSI reference model The benefit of application layer filtering is that it can understand applications and protocols and it can also detect if an unwanted protocol is sneaking through on a non-standard port or if a protocol is being used in any harmful way. An application firewall more secure and reliable as compared to packet filter firewalls as it works on all 7 layers of the OSI reference model, from the application to the physical layer. This is similar to a packet filter firewall but here it also filters information on the basis of content. In 2009/2010 the focus of the best comprehensive firewall security vendors turned to expanding the list of applications such firewalls are aware of now covering hundreds and in some cases thousands of applications which can be identified automatically. Many of these applications can not only be blocked or allowed but copied by the more advanced firewall products to allow only certain functionally enabling network security administrations to give users functionality without enabling unnecessary vulnerabilities. As a consequence these advanced versions of the Second Generation firewalls are being referred to as Next Generation and bypass the Third Generation firewall. It is expected that due to malicious communications this trend will have to continue to enable organizations to be truly secure. Third generation: stateful filters Fig8. Stateful filter Third-generation firewalls, in addition to what first- and second-generation look for, regard placement of each packet within the packet series. This technology is generally referred to as a stateful packet inspection as it maintains records of all connections going through the firewall and is able to determine whether a packet is the start of a new connection, a part of an existing connection, or is an invalid packet. Though there is still a set of defined rules in such a firewall, the state of a connection can itself be one of the criteria which trigger specific rules. This type of firewall can actually be exploited by certain Denial-of-service attacks which can fill the connections with illegitimate connections. Circuit-level gateway: Applies security mechanisms when a TCP or UDP connection is established. Once the connection has been done, packets can go between the hosts without checking further. Stateful filters Fig8. Stateful filter Third-generation firewalls, in addition to what first- and second-generation look for, regard placement of each packet within the packet series. This technology is referred to as a stateful packet inspection as it maintains records of all connections going through the firewall and is able to determine whether a packet is the start of a new connection, a part of an existing connection, or is an invalid packet. Though there is still a set of static rules in such a firewall, the state of a connection can itself be one of the criteria which trigger specific rules. This type of firewall can actually be abused by some Denial-of-service attacks which can fill the connection tables with false connections. Proxy servers Checks all messages entering and leaving the network. The proxy server hides the right network addresses. Fig9.Proxy server In computer networks, a proxy server is a server that acts as an intermediary for requests from clients seeking resources from other servers. A client connects to the proxy server, asking for some service, such as a file, connection, web page, or other resource, available from a different server. The proxy server processes the request according to its filtering rules. For example, it may filter traffic by IP address. If the request is passed by the filter, the proxy provides the resource by connecting to the relevant server and requesting the service on behalf of the client. A proxy server may alter the clients request or the servers response, and sometimes it may pass the request without contacting the specified server. In this case, it caches responses from the remote server, and sends back subsequent requests for the same content directly. Types of proxy Forward proxies Fig10.Forward proxies A forward proxy taking requests from an internal network and forwarding them to the Internet. Forward proxies are proxies where the client server names the target server to connect to. Forward proxies are able to get from a wide range of sources. The terms forward proxy and forwarding proxy are a general description of behavior (forwarding traffic) and hence ambiguous. Except for Reverse proxy, the types of proxies described on this article are more specialized sub-types of the general forward proxy concepts. Open proxies Fig11.Open proxies An open proxy forwarding requests from and to anywhere on the Internet. An open proxy is a forward proxy server that is accessible by any Internet user. Gordon Lyon estimates there are hundreds of thousands of open proxies on the Internet. An anonymous open proxy allows users to conceal their IP address while browsing the Web or using other Internet services. Reverse proxies Fig12.Reverse proxies A reverse proxy taking requests from the Internet and forwarding them to servers in an internal network. Those making requests connect to the proxy and may not be aware of the internal network. A reverse proxy is a proxy server that appears to clients to be an ordinary server. Requests are forwarded to one or more origin servers which handle the request. The response is returned as if it came directly from the proxy server. Reverse proxies are installed in the neighborhood of one or more web servers. All traffic coming from the Internet and with a destination of one of the web servers goes through the proxy server. The use of reverse originates in its counterpart forward proxy since the reverse proxy sits closer to the web server and serves only a restricted set of websites. There are several reasons for installing reverse proxy servers: Encryption / SSL acceleration: when secure web sites are created, the SSL encryption is often not done by the web server itself, but by a reverse proxy that is equipped with SSL acceleration hardware. See Secure Sockets Layer. Furthermore, a host can provide a single SSL proxy to provide SSL encryption for an arbitrary number of hosts; removing the need for a separate SSL Server Certificate for each host, with the downside that all hosts behind the SSL proxy have to share a common DNS name or IP address for SSL connections. This problem can partly be overcome by using the SubjectAltName feature of X.509 certificates. Load balancing: the reverse proxy can distribute the load to several web servers, each web server serving its own application area. In such a case, the reverse proxy may need to rewrite the URLs in each web page (translation from externally known URLs to the internal locations). Serve/cache static content: A reverse proxy can offload the web servers by caching static content like pictures and other static graphical content. Compression: the proxy server can optimize and compress the content to speed up the load time. Spoon feeding: reduces resource usage caused by slow clients on the web servers by caching the content the web server sent and slowly spoon feeding it to the client. This especially benefits dynamically generated pages. Security: the proxy server is an additional layer of defense and can protect against some OS and Web Server specific attacks. However, it does not provide any protection to attacks against the web application or service itself, which is generally considered the larger threat. Extranet Publishing: a reverse proxy server facing the Internet can be used to communicate to a firewalled server internal to an organization, providing extranet access to some functions while keeping the servers behind the firewalls. If used in this way, security measures should be considered to protect the rest of your infrastructure in case this server is compromised, as its web application is exposed to attack from the Internet. VPN A virtual private network (VPN) is a computer network that uses a public telecommunication infrastructure such as the Internet to provide remote offices or individual users with secure access to their organizations network. It aims to avoid an expensive system of owned or leased lines that can be used by only one organization. It encapsulates data transfers between two or more networked devices which are not on the same private network so as to keep the transferred data private from other devices on one or more intervening local or wide area networks. There are many different classifications, implementations, and uses for VPNs. Fig13 VPN Vulnerabilities:- Unauthorized access: This simply means that people who shouldnt use your computer services are able to connect and use them. For example, people outside your company might try to connect to your company accounting machine or to your network file server. There are various ways to avoid this attack by carefully specifying who can gain access through these services. You can prevent network access to all except the intended users. Exploitation of known weaknesses: Some programs and network services were not originally designed with strong security in mind and are inherently vulnerable to attack. The BSD remote services (rlogin, rexec, etc.) are an example. The best way to protect yourself against this type of attack is to disable any vulnerable services or find alternatives. With Open Source, it is sometimes possible to repair the weaknesses in the software. Denial of service: Denial of service attacks cause the service or program to cease functioning or prevent others from making use of the service or program. These may be performed at the network layer by sending carefully crafted and malicious datagrams that cause network connections to fail. They may also be performed at the application layer, where carefully crafted application commands are given to a program that cause it to become extremely busy or stop functioning. Preventing suspicious network traffic from reaching your hosts and preventing suspicious program commands and requests are the best ways of minimizing the risk of a denial of service attack. Its useful to know the details of the attack method, so you should educate yourself about each new attack as it gets publicized. Spoofing: This type of attack causes a host or application to mimic the actions of another. Typically the attacker pretends to be an innocent host by following IP addresses in network packets. For example, a well-documented exploit of the BSD rlogin service can use this method to mimic a TCP connection from another host by guessing TCP sequence numbers. To protect against this type of attack, verify the authenticity of datagrams and commands. Prevent datagram routing with invalid source addresses. Introduce unpredictability into connection control mechanisms, such as TCP sequence numbers and the allocation of dynamic port addresses. Eavesdropping: This is the simplest type of attack. A host is configured to listen to and capture data not belonging to it. Carefully written eavesdropping programs can take usernames and passwords from user login network connections. Broadcast networks like Ethernet are especially vulnerable to this type of attack Here are a few examples of firewalls :- Untangle Fortiguard Netnanny Websense ClearOS These firewalls can be affected by the above vulnerabilities. One way how a firewall/web filter can be bypassed is by using VPN. As studied above we can VPN to some external network and use that network. So we can bypass the firewall by doing VPN to a remote network and using its default gateway. Below are the precise steps how to setup a VPN server, Client, AD and LB configurations.

Comparing Hurrican Hits England and Not my Business Essay -- Grace Nic

Comparing Hurrican Hits England and Not my Business The two poems I am to compare are Grace Nichols â€Å"Hurricane Hits England† a poem that shows that the whole world is one world and how a storm reminds a Caribbean woman of home. The author obviously misses her home country and feels it in the storm which she wrote about, the violence of the storm is harsh and causes some damage. The second poem, with which I will be comparing â€Å"Hurricane...† is Niyi Osundare’s â€Å"Not my Business†. This poem describes the violent and horrific nature in which the Nigerian Government treated those people who disagreed with the state. It describes the pain and suffering they forced upon these people and how the pain and suffering is then brought to the narrator. This poem is about shared responsibilities and the way that tyranny grows if no one opposes it. It is composed, simply, of three stories about victims of the oppressors, followed by the experience of the speaker in the poem, in which he has not done anything, but the fact that he knows makes him a target. The poet is Nigerian but the situation in the poem could be from many countries, there are words used like â€Å"yam†, and the names of the people which tell you this. The poem echoes, in its four parts, a statement by Pastor Martin Niemà ¶ller, who opposed the Nazis. Speaking later to many audiences he would conclude with these words, more or less: â€Å"First, they came for the socialists, and I did not speak out because I was not a socialist. Then they came for the trade unionists, and I did not speak out because I was not a trade unionist. Then they came for the Jews, and I did not speak out because I was not a Jew. Then they came for me, and there was no one left to speak... ...oem. The last lines of this poem emphasise the confusion surrounding why they are there. The line, â€Å"The jeep was waiting on my bewildered lawn† is personification which suggests that no-one, not even his lawn, knows why it’s happening. And then a repetition of the word â€Å"Waiting† makes it seem as though the men have to do a lot of waiting and that time maybe seems to go so slowly because of these things that are happening. Both of these poems are excellent at enforcing their own point in their own ways, â€Å"Hurricane†¦Ã¢â‚¬  through tactile emotional words and beautiful yet violent images of the storm, and â€Å"Not My Business.† through blatant disregard for human life depicted through the eyes of a hunted man, who is hunted because he knows what is going on. All in all two excellent and well thought out poems, each with their own perfectly presented message.

“Harrison Bergeron” Versus “2081” Essay

There are many similarities between Kurt Vonnegut’s short story â€Å"Harrison Bergeron† and Chandler Tuttle’s short film adaptation â€Å"2081†. Obviously the same basic idea and theme are prevalent throughout both the stories. They are both set in the future where everyone is made equal by being forced to wear handicaps where they might show strength. Both of the stories involve the same characters in the same settings under mostly the same circumstances. The short film adaptation may vary a little bit in some of the details but for the most part both of the stories are exactly the same. In the beginning of â€Å"2081† the narration of the story is exactly the same as the beginning of Harrison Bergeron. Chandler Tuttle took it word for word straight from the short story. There are many differences between â€Å"Harrison Bergeron† and â€Å"2081† but they are mostly small details and do not change the story much. The first difference that I noticed when I watched â€Å"2081† was that instead of wearing bags filled with lead balls around their necks, the characters wore futuristic computer devices with a flashing display on them. The next subtle detail that I noticed was when George, one of the main characters, heard a loud noise coming through his earpiece in the beginning, it was Hazel who had suggested that it had sounded like a milk bottle being stuck by a ball peen hammer instead of George. One of the bigger differences between the two stories is the conversation between George and Hazel in the beginning of the story. In â€Å"Harrison Bergeron† when Hazel suggests to George that he rest his handicap weights on the pillows for a while, George responds by saying that he doesn’t mind them because he has worn them f or so long that he’s become accustomed to them. He then proceeds to explain to Hazel that if he tried to get away with it then other people would try to get away with it as well, and that would lead to everyone being against each other again and eventually to the dark ages. Hazel resounds that she would hate it if that were the case. However in the short film â€Å"2081† when Hazel suggests that George rest his weights for a while, George responds only implying that he himself would not be equal to Hazel to which she responds she would hate that. Also in the short story Harrison is arrested at age fourteen and escapes at age fourteen but in the short film the story takes place six  years after Harrison was arrested. The final main difference between â€Å"Harrison Bergeron† and â€Å"2081† is the â€Å"bomb†. In the short film adaptation when Harrison escapes from jail and bursts into the ballet he claims that he has a bomb stored under the theater and the detonator in hand. When the H-G men cut off the broadcast to the incident, Harrison presses the detonator button, revealing to the audience that the bomb was in fact a device that sent out the television broadcast once again. In the short story there is never any mention of any such device. There are many differences and many similarities between the short story â€Å"Harrison Bergeron† and the short film â€Å"2081†. However, throughout both stories the same theme remains prevalent throughout the entire stories conveying to the audience the same message, showing the beauty and necessity of diversity.

The Wild History of Roller Skates

The Wild History of Roller Skates An overview of the evolution of dry land skating aka roller skates. Early 1700s - Skeelers In Holland, an unknown Dutchman decided to go ice skating in the summer, ice skating was the widespread method used in the Netherlands to travel the numerous frozen canals in winter. The unknown inventor accomplished dry land skating by nailing wooden spools to strips of wood and attaching them to his shoes. Skeelers was the nickname given to the new dry-land skaters. 1760 - Crashing the Masquerade Party A London instrument maker and inventor, Joseph Merlin, attended a masquerade party wearing one of his new inventions, metal-wheeled boots. Joseph desiring to make a grand entrance added the pizzazz of rolling in while playing the violin. Lining the huge ballroom was a very expensive wall-length mirror. The fiddling skater stood no chance and Merlin crashed solidly into the mirrored wall, as his roller skates crashed into society. 1818 - Roller Ballet In Berlin, roller skates made a more graceful entrance into society, with the premier of the German ballet Der Maler oder die Wintervergn Ugungen (The Artist or Winter Pleasures). The ballet called for ice-skating but because it was impossible at that time to produce ice on a stage, roller skates substituted. 1819 - First Patent In France, the first patent for a roller skate issued to a Monsieur Petibledin. The skate was made of a wood sole that attached to the bottom of a boot, fitted with two to four rollers made of copper, wood or ivory, and arranged in a straight single line. 1823 - The Rolito Robert John Tyers of London patented a skate called the Rolito with five wheels in a single row on the bottom of a shoe or boot. The Rolito was unable to follow a curved path, unlike the in-line skates of today. 1840 - Barmaids on Wheels In a beer tavern known as Corse Halle, near Berlin, barmaids on roller skates served thirsty patrons. This was a practical decision, given the size of beer halls in Germany, which gave dry land skating a publicity boost. 1857 - Public Rinks Huge public rinks opened in the Floral Hall and in the Strand of London. 1863 - Inventor James Plimpton American, James Plimpton found a way to make a very useable pair of skates. Plimptons skates had two parallel sets of wheels, one pair under the ball of the foot and the other pair under the heel. The four wheels were made of boxwood and worked on rubber springs. Plimptons design was the first dry-land skate that could maneuver in a smooth curve. This considered the birth of the modern four-wheeled roller skates, which allowed for turns and the ability to skate backwards. 1884 - Pin Ball-Bearing Wheels The invention of pin ball-bearing wheels made rolling easier and skates lighter. 1902 - The Coliseum The Coliseum in Chicago opened a public skating rink. Over 7,000 people attended the opening night. 1908 - Madison Square Gardens Madison Square Gardens in New York became a skating rink. Hundreds of rink openings in the United States and Europe followed. The sport was becoming very popular and various versions of the roller skating developed: recreational skating on indoor and outdoor rinks, polo skating, ballroom roller dancing and competitive speed skating. 1960s - Plastics Technology (with the advent of new plastics) helped the wheel truly come of age with new designs. 70s 80s - Disco A second big skating boom occurred with the marriage of disco and roller-skating. Over 4,000 roller-discos were in operation and Hollywood began making roller-movies. 1979 - Redesigning Roller Skates Scott Olson and Brennan Olson, brothers and  hockey  players who lived in Minneapolis, Minnesota, found an antique pair of roller skates. It was one of the early  skates  that used the in-line wheels rather than the four-wheeled parallel design of George Plimpton. Intrigued by the in-line design, the brothers began redesigning roller skates, taking design elements from the found skates and using modern materials. They used  polyurethane  wheels, attached the skates to ice hockey boots, and added a rubber toe-brake to their new design. 1983 - Rollerblade Inc Scott Olson founded Rollerblade Inc and  the term rollerblading  meant the sport of in-line skating because Rollerblade Inc was the only manufacturer of in-line skates for a long time. The first mass-produced rollerblades, while innovative had some design flaws: they were difficult to put on and adjust, prone to collecting dirt and moisture in the ball-bearings, the wheels were easily damaged and the brakes came from the old roller skate toe-brake and were not very effective. Rollerblade Inc Sold The Olson brothers sold Rollerblade Inc and the new owners had the money to really improve the design. The first massively successful Rollerblade skate was the Lightning TRS. In this pair of  skates  the flaws had vanished, fiberglass was used to produce the frames, the wheels were better protected, the skates were easier to put on and adjust and stronger brakes were placed at the rear. With the success of the Lightning TRS, other in-line skate companies appeared: Ultra Wheels, Oxygen,  K2  and others. 1989 - Macro and Aeroblades Models Rollerblade Inc produced the Macro and Aeroblades models, the first skates fastened with three buckles instead of long laces that needed threading. 1990 - Lighter Skates Rollerblade Inc switched to a glass-reinforced thermoplastic resin (durethan  polyamide) for their skates, replacing the  polyurethane  compounds previously used. This decreased the average weight of skates by nearly fifty percent. 1993 - Active Brake Technology Rollerblade, Inc. developed ABT or Active Brake Technology. A fiberglass post attached at one end to the top of the boot and at the other end to a  rubber-brake,  hinged the chassis at the back wheel. The skater had to straighten one leg to stop, driving the post into the brake, which then hit the ground. Skaters had been tilting their foot back to make contact with the ground, before ABT. The new brake design increased safety. Presently the best way for you to experience the latest inventions in the world of wheels is up-close and personal. Please do so, try in-line skating and keep rolling.

Free Essays on Fellowship Of The Craft Free Essays on Fellowship Of The Craft â€Å"The Fellowship of the Craft† The â€Å"fellowship of the craft† is truly the most important aspect of a crew, and therefore of their ship and her voyage. This fellowship or comradery is the tie that binds the men together, with common goals, views and especially the trust the afore mentioned bring, making the fellowship the life-blood of a vessel. Authors of sea literature illustrate and utilize this fellowship in numerous ways, helping to give the unknowing, unsea-worthy reader an opportunity to better understand this mystical connection. The fellowship of the craft is an extraordinarily complex inter-relationship of crew, captain & inevitably, the sea herself.
