Modification of an organism or its parts that makes it more fit for existence under the conditions of its environment.
The gaseous envelope of a celestial body (such as a planet).
Any technique that uses living organisms, or part of organisms, to make or modify products, improve plants and animals, or to develop micro organisms for specific uses.
The average course or condition of the weather at a place, usually over a period of years as exhibited by temperature, wind velocity, and precipitation.
The successful transmission of information through a common system of symbols, signs, behavior, speech, writing, or signals.
A material capable of transmitting another form of energy (such as heat or sound).
A limit to the design process caused by such things as appearance, funding, space, materials, and human capabilities.
The systematic act or process of building or erecting buildings, roads or other structures.
An organism requiring complex organic compounds for food which it obtains by preying on other organisms or consuming particles of organic matter.
Any of various organisms (as with many bacteria and fungi) that return constituents of organic substances to ecological cycles by feeding on and breaking down dead protoplasm.
An iterative decision-making process that produces plans by which resources are converted into products or systems to meet human needs or wants or to solve problems.
Design Brief
A written plan that identifies a problem to be solved, its criteria, and its constraints. The design brief is used to encourage thinking of all aspects of a problem before attempting a solution.
Design Principle
Design rules regarding rhythm, balance, proportion, variety, emphasis, and harmony, used to evaluate existing designs and guide the design process.
The complex of a community of organisms and its environment functioning as an ecological unit.
Electric Circuit
The complete path of an electric current including usually the source of the electric energy.
Electric Current
A flow of electric charge.
The capacity for doing work.
A person who is trained in and uses technological and scientific knowledge to solve practical problems.
The profession of or work performed by an engineer. Engineering involves the knowledge of the mathematical and natural sciences (biological and physical) gained by study, experience and practice that are applied with judgment and creativity to develop ways to utilize the materials and forces of nature for the benefit of human kind.
Engineering Design
The systematic and creative application of scientific and mathematical principles to practical ends such as design, manufacture, and operation of efficient and economical structures, machines, processes and systems.
The complex of physical, chemical and biotic factors (such as climate, soil and organisms) that act upon an organized ecological community and ultimately determine its form and survival.
The gradual wearing away of rock or soil by physical breakdown, chemical solution, and transportation of material as caused, for example, by water, wind or ice.
