The detection limit is conventionally defined as field blank + 3σ, where σ is the standard deviation of the field blank value signal (IUPAC definition).

Mathematically and statistically, the width or risk of a variable can be measured through several different statistics, including the range, standard deviation (σ), variance, coefficient of variation, and percentiles.

Summation of changes in private housing rentals for all floor area types in the simulated CSSA rent index.

Our practice in the company's operations is generally a widespread adoption of internationally recognized (example: 6 σ, CMMI, etc.) or software vendor recommended (such as Microsoft Sure Step, etc.) standards, which are properly tailored based on the actual implementation of each project environment, project situation and customer requirements to develop high efficiency, high-quality, and in line with the client’s best interests.

The AD7176-2 is a fast settling, highly accurate, high resolution, multiplexed Σ-Δ analog-to-digital converter (ADC) for low bandwidth input signals.

Sangwoo Lee was awarded for the thesis entitled "Structure and Dynamics of Block Copolymer Based Soft Materials" for "the discovery of sigma phases of block co-polymers, which combine features of crystallinity and glass-like behavior, and characterizing these novelphases exhaustively.

Audio equipment should not be installed directly onto the architectural structure. It is advised to apply vibration isolation materials, and the specifications for such vibration isolation materials are: transfer ratio (T) of 0.01~0.05, vibration isolation efficiency (η) of 95~99%, frequency ratio (f/fo－the ratio between fixed frequency of vibration isolation system and driver frequency of vibration equipment) of 5.5~15.

η——for centralized heating system, η refers to coefficient for loss of hot water during transportation and distribution as well as power consumption; for home air-conditioners in winter, η refers to the coefficient of performance of air-conditioning system in winter.

While calculating the energy quality coefficient of primary energy sources, it is necessary to consider energy losses in the dynamic devices, such as the heat transfer caused by temperature difference and loss of dynamic power, which means considering the average energy conversion efficiency η. For gas, fuel oil, and coal, η＝0.8.

(b) with deletions made in accordance with the instructions specified in those provisions as marked with an asterisk (*), a gamma (γ), a beta (β), a theta (θ), a pi (π), a sigma(Σ), an omega (Ω) or a psi (Ψ).

It is advised to apply vibration isolation materials, and the specifications for such vibration isolation materials are: transfer ratio (T) of 0.01~0.05, vibration isolation efficiency (η) of 95~99%, frequency ratio (f/fo－the ratio between fixed frequency of vibration isolation system and driver frequency of vibration equipment) of 5.5~15.

To compute the volatility (σ) used in an equivalent computation (regardless of whether it is used in simulation, lattices, or closed-form models because these three approaches require the Brownian Motion as a fundamental assumption), a natural log is used.
