Abstract. The TOPAS (Tikhonov regularised Ozone Profile retrievAl with SCIATRAN) algorithm to retrieve vertical profiles of ozone from space-borne observations in nadir-viewing geometry has been developed at the Institute of Environmental Physics (IUP) of the University of Bremen and applied to the TROPOspheric Monitoring Instrument (TROPOMI) L1B spectral data version 2. Spectral data between 270 and 329 nm are used for the retrieval. A recalibration of the measured radiances is done using ozone profiles from MLS/Aura. Studies with synthetic spectra show that individual profiles in the stratos

Abstract:

The voice range profile (VRP) is a display of vocal intensity range versus fundamental frequency (F 0 ). Past measurements have shown that the intensity range is reduced at the extremes of the F 0 range, that there is a gradual upward tilt of the high- and low-intensity boundaries with increasing F 0 , and that a ripple exists at the boundaries. The intensity ripple, which results from tuning of source harmonics to the formants, is more noticeable at the upper boundary than the lower boundary because higher harmonics are not energized as effectively near phonation threshold as at maximum lung

Abstract:

Hyperspectral LiDAR (HSL) has been utilized as an efficacious technique in object classification and recognition based on its unique capability to obtain ranges and spectra synchronously. Different kinds of HSL prototypes with varied structures have been promoted and measured its performance. However, almost all of these HSL prototypes employ complex and large spectroscopic devices, such as an Acousto-Optic Tunable Filter and Liquid-Crystal Tunable Filter, which makes this HSL system bulky and expensive, and then hinders its extensive application in many fields.

Spectral pyrometry was used to determine the surface temperature distribution of Si, Nb, Cu, and graphite samples when they were locally heated by continuous radiation of an Nd:YAG laser (λ = 1.064 μm).

The thermal spectra were recorded with a small spectrometer in the visible range in the temperature range above 850 K.

A unified approach is developed for calculating the spectral line profiles of atoms in an alternating electric field based on the diagonalization of the energy matrix of an atom in the field. To calculate the Stark profile of the spectral line, a formula is proposed in which the profile width contains an explicit dependence on the electric field parameters. The algorithm of the method is implemented in the StarkD software package written in FORTRAN and Maple. Within the framework of the proposed approach, computer modeling of the spectral line profiles of He, Ne, and Ar atoms in terahertz elec

Abstract The pulsar profile is characterized by two distinct emission components, the core and the cone. The standard model of a pulsar radio emission beam originating from dipolar magnetic fields places the core at the center surrounded by concentric layers of inner and outer conal components. The core emission is expected to have steeper spectra compared to the cones. We present a detailed analysis of the relative differences between the spectra of the core and conal emission from a large sample of 53 pulsars over a wide frequency range between 100 MHz and 10 GHz.

However, recent studies have indicated that children with dyslexia often exhibit combinations of deficits across different cognitive domains.

The temporal profile of mid- and far-infrared light pulses can thus not be measured directly using a conventional streak camera.
