A compact low-stiffness six degrees of freedom compliant precision stage statically balanced (i.e. near zero stiffness) to neutralize the gravity force and cancel out the stiffness due to the compliant design of the structure... AG Dunning,N Tolou,JL Herder - 《Precision Engineering》 被引量...
There are various facilities around the world implementing different technologies and strategies for on-ground emulation of in-orbit operations for different orbital scenarios, that represent micro-gravity at different degrees of freedom (DoF). Some facilities [7], [8], [9], [10] use robotic arm...
When buildings account for around one-third of global energy consumption and 20 percent of CO2emissions (as much as 50 percent in major cities2), anything we can do to make them more efficient is positive. To reach the Paris target of limiting global warming to 1.5 degrees Celsius, however...
Lendlease has embarked on a series of partnerships to help the industry limit global warming to 1.5 degrees Celsius.
As mentioned before, most practical control systems have plants with nonzero relative degrees, i.e., plants with strictly proper transfer functions. For these systems, the Nyquist contour of the plant 𝐺𝑝(𝑠) (and, hence, 𝐺𝑚(𝑧)) tends toward point (0,0) of the complex plane...

Biomass is mainly used in pulp and paper industries and in sawmills, while electricity is used in most sectors to various degrees. Fossil fuels are mainly used for production of steel from iron ore, production of cement, and production of olefins in the petrochemical industry. These are all ...
This happens by no chance: in the case of heat exchanger design, examined in this work, the specifications are quite stringent, and if additional symmetries are imposed by the selection of the device shape, the number of “design degrees of freedom” drops to zero. This does not imply that...

shadow Saas applications may not be encrypted, patched rarely, or audited for vulnerabilities; they hence expose themselves to far greater degrees of cyber-attacks as a result. Global Zero Trust Security Market Ecosystem Analysis By vertical, the IT&ITeS segment is to account for a larger market...
