Base isolators for seismic isolation of buildings, bridges, etc. Base isolators made of layers of neoprene and steel with a low horizontal stiffness are used to lower the natural frequency of the building. Some other base isolators are designed to slide, preventing the transfer of energy from the ground to the building. Tuned mass dampers
Temperature distribution in a thermal bridge This thermal image shows a thermal bridging of a high-rise building (Aqua in Chicago). A thermal bridge, also called a cold bridge, heat bridge, or thermal bypass, is an area or component of an object which has higher thermal conductivity than the surrounding materials, [1] creating a path of least resistance for heat transfer. [2]
The calculation of the heat loss due to linear thermal bridging is relatively simple, given by the formula below: [3] H T B = y ∑ A e x p {\displaystyle H_{TB}=y\sum A_{exp}} In the formula, y = 0.08 {\displaystyle y=0.08} if Accredited Construction details used, and y = 0.15 {\displaystyle y=0.15} otherwise, and ∑ A e x p {\displaystyle ...
Vehicle emissions control is the study of reducing the emissions produced by motor vehicles, especially internal combustion engines.The primary emissions studied include hydrocarbons, volatile organic compounds, carbon monoxide, carbon dioxide, nitrogen oxides, particulate matter, and sulfur oxides.
Highway engineering (also known as roadway engineering and street engineering) is a professional engineering discipline branching from the civil engineering subdiscipline of transportation engineering that involves the planning, design, construction, operation, and maintenance of roads, highways, streets, bridges, and tunnels to ensure safe and effective transportation of people and goods.
ATEGs allow the automobile to generate electricity from the engine's thermal energy rather than using mechanical energy to power an electric generator. Since the electricity is generated from waste heat that would otherwise be released into the environment, the engine burns less fuel to power the vehicle's electrical components, such as the ...
A regenerative thermal oxidizer (RTO) is an example of a waste heat recovery unit that utilizes a regenerative process. A waste heat recovery unit ( WHRU ) is an energy recovery heat exchanger that transfers heat from process outputs at high temperature to another part of the process for some purpose, usually increased efficiency.
Inherent fail-safes are common in medical equipment, traffic and railway signals, communications equipment, and safety equipment. The typical approach is to arrange the system so that ordinary single failures cause the mechanism to shut down in a safe way (for nuclear power plants, this is termed a passively safe design, although more than ...
