Phycocyanin-specific absorption coefficient: Eliminating the effect of chlorophylls absorption
The applicability of algorithms for estimation of phycocyanin (PC) concentration based on light spectral reflectance heavily depends on the specific absorption of the pigment. But the determination of PC-specific absorption coefficient is not a straightforward task, as PC optical activity is overlapped by absorption of chlorophylls. The aim of our study was to determine a PC(625)—the specific a...
متن کاملVariability of BAC/BrAC, BAC/SAC and SAC/BrAC Ratios During Absorption and Elimination of Alcohol
A group of 38 volunteers participated in 74 experiments with multiple collection of blood and saliva samples and simultaneous breath testing. BAC/BrAC, BAC/SAC and SAC/BrAC ratios were calculated for every sampling time for each examined person in each experiment. It gave 975 values of the distribution ratio of ethanol for each system. The mean values of BAC/BrAC ratio calculated for absorption...
متن کاملRegularity of the Interband Light Absorption Coefficient
In this paper we consider the Interband Light Absorption Coefficient (ILAC), in a symmetric form, in the case of random operators on the d-dimensional lattice. We show that the symmetrized version of ILAC is either continuous or has a component which has the same modulus of continuity as the density of states.
متن کاملAn alternative coefficient for sound absorption
The acoustic absorption coefficient is a number that indicates which fraction of the incident acoustic power impinging on a surface is being absorbed. The incident acoustic power is obtained by spatial integration of the incident intensity, which is (classically) defined as the time-averaged intensity associated with the incident sound field. The measurement of the effective, in situ, sound abs...
متن کاملRobust Speech Recognition Using Wavelet Coefficient Features
We propose a new vein of feature vectors for robust speech recognition that use denoised wavelet coefficients. Greater robustness to unexpected additive noise or spectrum distortions begins with more robust acoustic features. The use of wavelet coefficients is motivated by human acoustic process modelling and by the ability of wavelet coefficients to capture important time and frequency feature...
