Rate of Change: The speed at which a variable changes over a specific period of time. It is often used when speaking about momentum, and it can generally be expressed as a ratio between a change in one variable relative to a corresponding change in another. Graphically, this ratio is repre...
For example, the US-SPF asks for density forecasts of the annual rate of GDP deflator inflation in the year of the survey relative to the previous year and of the next year relative to the current year, that is, of the percentage rate of change in the annual GDP deflator between years....
At higher than 30 m/s, the momentum effects become significant to affect the flow distribution. By making the inlet and outlet of double size, the flow distribution deviation reduced four times while doubling the length of the flow channels reduced the standard deviation by a factor of 1.7. ...
merchants accepting bitcoins often pay fees of 0% to less than 2% of the total purchase. Despite the fourfold increase in the number of merchants accepting bitcoin in 2014, the cryptocurrency did not have much momentum in retail transactions. The European Banking Authority and other sources have ...

of mutual funds over the same period. We anticipate this strong momentum to persist, driven by two key factors: (1) the potential expansion into fixed-income assets which remain underrepresented in ETFs. For example, in the US, ETFs accounted for 13% of total equity assets, but only 2.8%...
The main obstacle to the formation of second-generation (2g) BHs via hierarchical mergers is the high relativistic kick that the merger remnant receives at birth because of radiation of linear momentum through beamed GW emission (e.g., [90,91,92,93]). This kick can be up to several ...
A first-order reaction is a chemical reaction in which the rate of the reaction is directly proportional to the concentration of the reactants. Put another way, the rate of a first-order reaction only changes when the concentrations of reactants change. If more reactants are added, the ra...
At present, our country is in the middle period of industrialization, automobile, steel, machinery, tooling, electronics, chemical and other a group with heavy industry as the foundation of the high growth momentum of development of the industry is strong, the future market of machine tool especi...
The direct method is accomplished by measuring the momentum, Coriolis force and other parameters which are directly related to mass flow, the representative devices are angular momentum meter, Coriolis mass flow meter (CMFM), gyroscopic mass meter. Unlike the direct method, the thermal method ...
