The tip-speed ratio, λ, or TSR for wind turbines is the ratio between the tangential speed of the tip of a blade and the actual speed of the wind, v. The tip-speed ratio is related to efficiency, with the optimum varying with blade design. [1] Higher tip speeds result in higher noise levels and require stronger blades due to larger centrifugal ...
The definition of EVM depends heavily on the standard that is being used, for example in 3GPP LTE the relevant documents will define exactly how EVM is to be measured. There are discussions ongoing by academics as to some of the problems around EVM measurement. [3]
FTSE Russell is a subsidiary of London Stock Exchange Group (LSEG) that produces, maintains, licenses, and markets stock market indices. [1] The division is notable for the FTSE 100 Index in the UK and the Russell 2000 Index in the US, among others.
The relative gain array (RGA) is a classical widely-used [citation needed] method for determining the best input-output pairings for multivariable process control systems. [1] It has many practical open-loop and closed-loop control applications and is relevant to analyzing many fundamental steady-state closed-loop system properties such as ...

For example, corresponding to the S&P 500 index calculated by Standard and Poor's, there is the S&P 500 TR index. In the technology sector, a study has found that regardless of a company's size, the more diverse the portfolio, the more difficult it is to generate high TSR.
Consider another example to calculate the annualized ordinary rate of return over a five-year period of an investment that returns 10% p.a. for two of the five years and -3% p.a. for the other three. The ordinary time-weighted return over the five-year period is:
In high throughput sequencing, data obtained are typically transformed to relative abundances, rendering them compositional. In probability and statistics, a partition of the sampling space into disjoint events is described by the probabilities assigned to such events. The vector of D probabilities can be considered as a composition of D parts ...
