entities are objects outside the system‚ with which the system communicates. External entities are sources and destinations of the system’s inputs and outputs. 1.b) ENTITY RELATIONSHIP DIAGRAM Entity–relationship model (ER model) in software engineering is an abstract way to describe a database. This article refers to the techniques proposed in Peter Chen’s 1976 paper.An ER model is an abstract way to describe a database. There are three basic elements in ER models: Entities are the "things"

Tissue engineering By Nathan. F Introduction Tissue Engineering is the use of a combination of cells‚ engineering and materials methods‚ and suitable biochemical and physio-chemical factors to improve or replace biochemical functions. The objective of tissue engineering is to create living body parts that will fully integrate with the recipient’s body. Tissue engineering mostly associated with applications that repair or replace portions of or whole tissues. For example bone‚ cartilage

Gerica Roberts 822 January 4‚ 2012 Ms. Buie Genetic Engineering Genetic engineering is a laboratory technique used to change or modify the DNA of any subject to create a new substance or functions. This method changes the genes‚ in which was passed down from the biological parents. These modified test subjects might not become super objects but they sure are wired and fixed different from the rest of the naturally made things. Techniques allows scientist to determine the charac

Genetic Engineering The engineering of deoxyribonucleic acid (DNA) is entirely new‚ yet genetics‚ as a field of science‚ has fascinated mankind for over 2‚000 years. Man has always tried to bend nature around his will through selective breeding and other forms of practical genetics. Today‚ scientists have a greater understanding of genetics and its role in living organisms. Unfortunately‚ some people are trying to stop further studies in genetics‚ but the research being conducted today will serve

Virtues in Engineering William F. May said of the expert: “He had better be virtuous. Few may be in a position to discredit him. The knowledge explosion is also an ignorance explosion; if knowledge is power‚ then ignorance is powerlessness” (Harris 30). In the context of engineering‚ this places engineers in a very special position. Because of this power‚ which few may ever possess‚ it becomes necessary for engineers to be virtuous or posses certain attributes for the welfare of the public

Computer Engineering As we know‚ "Computer engineers are involved in the design and development of operating systems‚ compilers and other software that requires efficient interfacing with the components of the computer" [1]. Computer Engineering is most appropriate for my future plans. It will challenge my skills to learn how to design and develop hardware and software. Even though there are disadvantages pursuing a career in Computer Engineering‚ there are also advantages such as what it

Chemical Engineering In the future I would like to become a chemical engineer. I really enjoy chemistry and hands on work “Chemical engineering is the application of chemistry to large scale industrial systems.” (Chemical engineering). I enjoy helping build different things like skateboards‚ ramps and‚ fixing parts on different things. When I took the sixteen personality quiz it said I was a virtuoso. The virtuoso likes hands on work and exploring ideas which I think fits my personality perfectly
