Modeling every building in America starts with Chattanooga

Buildings use 40 percent of America's primary energy and 75 percent of its electricity, which can jump to 80 percent when a majority of the population is at home using heating or cooling systems and the seasons reach their ...

New exploration method for geothermal energy

Where to drill? This is the basic question in the exploration of underground energy resources, such as geothermal energy. Water in rocks flows along permeable pathways, which are the main target for geothermal drilling. Borehole, ...

New technique lets researchers map strain in next-gen solar cells

People can be good at hiding strain, and we're not alone. Solar cells have the same talent. For a solar cell, physical strain within its microscopic crystalline structure can interrupt its core function—converting sunlight ...

Robotics

Assembler robots make large structures from little pieces

Today's commercial aircraft are typically manufactured in sections, often in different locations—wings at one factory, fuselage sections at another, tail components somewhere else—and then flown to a central plant in ...

Structure

Structure is a fundamental and sometimes intangible notion covering the recognition, observation, nature, and stability of patterns and relationships of entities. From a child's verbal description of a snowflake, to the detailed scientific analysis of the properties of magnetic fields, the concept of structure is an essential foundation of nearly every mode of inquiry and discovery in science, philosophy, and art.

A structure defines what a system is made of. It is a configuration of items. It is a collection of inter-related components or services. The structure may be a hierarchy (a cascade of one-to-many relationships) or a network featuring many-to-many relationships.
