Graphic Techniques and Fundamental of the Next Generation CAD/E System Computer-Aided Design also known as CAD has become very popular since the early 1990s. CAD drawings are designed to help engineer physically visualize the solutions for our everyday problems. We are going to look over some the fundamentals of the next generation CAD and engineer systems‚ as well as some new techniques and methods to construct a more detailed and advanced graphics with CAD softwares. The first article I reviewed

Inquiry Method Steps 1. Ask a question or identify the problem – What do you want to learn about? This question forms the starting point for inquiry. Example: You may be interested in discovering what methods of studying lead to better exam results. 2. Develop a hypothesis – A hypothesis is possible answer to your research question. Your hypothesis gives you direction. It helps you to determine what needs to be tested and which research method you will use. Example: You may hypothesize that

Different assessment methods available within NVQ’s in the transport industry. Most of my job requires me to record evidence of a person carrying out their daily work routine and sees me recording them doing it using a range of assessment methods. The main assessment method that I prefer to use is Holistic. The reason I prefer using this method above other methods available to me is because it allows me to record any evidence as I see it occur in the workplace naturally. As no two assessments

“We are a bunch of pussies‚” replied Justin Singh-Courtney‚ a freshman at University California‚ Davis‚ to a very simple question: Is our (current college students) generation more sensitive than our parents’ generation? As high schools and college have begun incorporating more trigger warnings‚ diversity trainings‚ and awareness days it has become a pressing issue as to the line where sensitivity ends and coddling begins. Greg Lukianoff and Jonathan Haidt wrote a piece for The Atlantic claiming

In the article “ The Distracted Generation” written by Simon Sinek‚ claims are made that millennials are trying to do multiple things at once and would preferably give little efforts to multiple things rather than focus all their efforts on one thing. Sinek believe that this “need” to multitask leads to unhappy teenagers because of how alone this type of system can make one feel. Sinek also writes that this is happening because technology is making millennials believe that we are better at multitasking

The First Generation of Computers The first generation of computers‚ beginning around the end of World War 2‚ and continuing until around the year 1957‚ included computers that used vacuum tubes‚ drum memories‚ and programming in machine code. Computers at that time where mammoth machines that did not have the power our present day desktop microcomputers. In 1950‚ the first real-time‚ interactive computer was completed by a design team at MIT. The "Whirlwind Computer‚" as it was called

Describe the scientific method of research. Be sure to identify the key components‚ providing examples of each. Use external sources to support your answer. The methods of science are the methods of all correct thinking. In all thinking we are concerned with getting and organizing knowledge‚ or with testing‚ applying‚ and developing the knowledge we have already acquired (Jones‚ 1909). According to Zikmund‚ Babin‚ Carr‚ and Griffin‚ “the scientific method is a set of prescribed procedures for
