CAD-Computer Aided Design :: Computer Science

CAD-Computer Aided Design Computer Aided Design systems make it easy to create a picture of a new design, then you are able to change the picture on the computer. This saves time because you don’t have to re draw everything from the way it was originally started of with. It is also quicker to evaluate. There are many different types of CAD programs available to the industries and designers. They are concerned with either the visual appearance of the product or the technical details and difficulties. Computers have become as integral part of the design. They can dramatically cut down on labour and time and also costs. Garments have to have production patterns made. From these you can then alter the sizes, shapes, styles etc The process of changing a pattern size is called â€Å"Grading.† Grading is mathematical and involves working out smaller measurements, having to make each pattern piece bigger or smaller. Computers are used to do this because it makes the process much quicker and accurate Cad has a number of advantages -Data from pattern-making programs can be used to instruct machines to cut pieces out from lengths of fabric -Drawings or designs can be scanned into the computer and a wide range of repeat patterns and colour options generated in minutes. -The finished fabrics can be chosen from the screen by a client or customer and then printed using a digital printer. This is a big advantage for companies or industries using a one-off production, where they are making a garment to meet the standards and desirable needs of one particular customer. Them being able to choose their desired fabric/material is an advantage for the company as they are making something the customer chose themselves. -Changes can be made quickly as a customer waits. -Designs can be stored at a late date is then changed -Images can be sent electronically, directly to the client to view and have their opinions towards it. Disadvantages -There is an initial training period before the software can be used. -The software is also expensive. Therefore, other clients or factories may not have the same software. -If there is a problem with the computers, then all the work Is on hold, until an engineer is present to fix the problem. CAD helps speed up the entire design, manufacturing and retail process. The more new styles mean more sales are generated. Some stores want a new garment produced for them every month to maximise variety. More ICT in the Textiles Industry Using the internet, textile companies can now receive information and daily industry news 24 hours a day, from around the world.

How Information Flows Within An Organization Essay

Information Flow Must Be Relevant and Specific Although there exists an age-old saying â€Å"too much information is never enough,† specific need must be established in order to disseminate information properly. Without specific guidelines, information flood inhibits the ability to tailor the data for use and brings up privacy issues, which must ultimately be addressed and mitigated. In the military, there exists a multitude of data and information that is passed on a daily basis. From supply and logistics information, medical and dental information, and tactical and technical information, the information needed to operate and maintain a small piece of the military is exponential. Without clear and structured guidelines on how that information is collected and used, our military would be faced with an inordinate amount of data, but with no real method of using the information. The information must also be stored within systems that provide access to relevant information, and at the same time ensure that the contents of those systems are able to withstand any and all attempts to circumnavigate the security measures within the system. Within the organization, there are a different types of information. One such type is personal information dealing with individuals. Sensitive information like medical history, dental history, and current prescriptions is information that must be limited to the service providers, while still maintaining the privacy and security of the individual. For that reason, systems are developed to run on an independent network that limits medical facilities and their providers with this  information. From the doctor or nurse’s input into the system, this information is maintained on databases and servers that are secured, allowing access only to those systems that have a vested interest in the patient. Departments such as pharmacy, appointment scheduling, and referrals will all be allowed some access to an individual’s information. The delineating factor in providing this information is the ability to limit these different systems to only the information necessary to provide proper care. One example is a pharmacy knowing what type of medication a person needs without the entire medical history being on display for all within the pharmacy to view. Another example is information about specific, day-to-day operations. Within an organization, even a secure facility, information that is discussed and passed does not always warrant access by everyone within the facility. That is why classifications exist, in order to minimize the access of information to only those who are authorized while keeping records of where the information has been. With classified information, the method must also exist to transport the information using today’s technologies. A secure, independent network exists within the military that provides a transport strictly for secure and classified information called The Secret Internet Protocol Router Network (SIPRNet, or SIPR). Another system, used for less sensitive information, is called The Non-Classified Internet Protocol Router Network (NIPRNet, or NIPR). NIPR is divided internally in the organization through the use of different Virtual Local Area Networks (VLAN’s) to allow different departments within the organization to communicate with each other without fear of overlapping their information with other agencies. NIPR is also widely known as the typical internet for the military since normal internet access is located within NIPR. Collectively, these two systems provide the military and its organizations to function and communicate on a daily basis, allowing the required departments and personnel access to relevant information without fear of privacy concerns. It can be argued that today’s society is dependent on information and that too much information is never enough. Some would argue that with more information at its disposal, companies, products and governments could provide better support and a higher standard of living for all. However, it is inherent on organizations with desires of a multitude of information to limit their scope of to the necessary information, in  order to prohibit information from being used in a hurtful or destructive manner. Ultimately, information flow starts and ends with the individual. It is the individual that provides information, transports information, and ultimately accesses information. It is the individual that must be the one who ensures that information is being handled in methods that serves its purpose, but does not infringe on the privacy of others.

Scythians in the Ancient World

Scythians -- a Greek designation -- were an ancient group of people from Central Eurasia distinguished from others of the area by their customs and their contact with their neighbors. There appear to have been several groups of Scythians, who were known to the Persians as Sakas. We dont know where each group lived, but they lived in the area from the Danube River to Mongolia on the East-West dimension and southward to the Iranian plateau. Where the Scythians Lived Nomadic, Indo-Iranian (a term that also covers inhabitants of the Iranian plateau and the Indus Valley [e.g., Persians and Indians]) horsemen, archers, and pastoralists, depicted wearing pointed hats and trousers, the Scythians lived in the Steppes northeast of the Black Sea, from the 7th-3rd century B.C. Scythia also refers to a region from the Ukraine and Russia (where archaeologists have unearthed Scythian burial mounds) into Central Asia. Eurasian Map showing Steppe tribes, including SythiansRelated map showing location in Asia, as well The Scythians are closely associated with horses (and the Huns). [The 21st-century movie Attila showed a starving boy drinking the blood of his horse to stay alive. However much this might be Hollywood license, it conveys the essential, survival bond between the steppe nomads and their horses.] Ancient Names of the Scythians The greek epic poet Hesiod called the northern tribes hippemolgi mare milkers.The Greek historian Herodotus refers to the European Scythians as Scythians and the eastern ones as Sacae. Beyond the Scythians and other Steppe tribes was supposed to be Apollos sometimes home, among the Hyperboreans.The name Scythians and Sacae applied to themselves was Skudat archer.Later, the Scythians were sometimes called Getae.The Persians also called the Scythians Sakai. According to Richard N. Frye (The Heritage of Central Asia; 2007) of these, there wereSaka HaumavargaSaka Paradraya (beyond the sea or river)Saka Tigrakhauda (pointed hats)Saka para Sugdam (beyond Sogdiana)Scythians, who attacked the kingdom of Urartu in Armenia, were called Ashguzai or Ishguzai by the Assyrians. The Scythians may have been the Biblical Ashkenaz. Legendary Origins of the Scythians A rightly skeptical Herodotus says the Scythians claimed the first man to exist in the region -- at a time when it was desert and about a millennium before Darius of Persia -- was named Targitaos. Targitaos was the son of Zeus and the daughter of the river Borysthenes. He had three sons from whom the tribes of the Scythians sprang.Another legend Herodotus reports connects the Scythians with Hercules and Echidna. Tribes of the Scythians Herodotus IV.6 lists the 4 tribes of the Scythians: From Leipoxais sprang the Scythians of the race called Auchatae;from Arpoxais, the middle brother, those known as the Catiari and Traspians;from Colaxais, the youngest, the Royal Scythians, or Paralatae.All together they are named Scoloti, after one of their kings: the Greeks, however, call them Scythians. The Scythians are also divided into: Sacae,Massagetae (may mean strong Getae),Cimmerians, andGetae. The Appeal of the Scythians The Scythians are connected with a variety of customs that interest modern people, including the use of hallucinogenic drugs, fabulous gold treasures, and cannibalism [see Cannibalism in ancient myth]. They have been popular as the noble savage from the 4th century B.C. Ancient writers eulogized the Scythians as more virtuous, hardy, and chaste than their civilized contemporaries.
