Estimating (co)variance parameters of a random regression model for test day yields of dairy cattle has been proven to be a challenging task due to the complexity of (co)variance structure of the test day yields. Two common approaches have been practised so far for the estimation of parameters: direct random regression model approach and indirect covariance functions (CF) approach. Animal genet...

Fourier decompositions are performed for the light curves of six RRab and 3 RRc field stars. These are added to previous work to form a sample of 61 RRab and 12 RRc pulsators. The RRab stars are divided into two groups-a short-period (SP) group with P < 0~575 and a long-period (LP) group with P > 0~575. The Fourier phase parameter CP21 is found to fall off very regularly with decreasing metalli...

Surface concentrations of particulate organic carbon (POC) in shallow inland lakes were estimated using MODIS Aqua data. A power regression model of the direct empirical relationship between POC and the atmospherically Rayleigh-corrected MODIS product (Rrc,645Rrc,1240)/(Rrc,859-Rrc,1240) was developed (R 2 = 0.72, RMSE= 35.86 μgL, p< 0.0001, N = 47) and validated (RMSE= 44.46 μgL, N= 16) with f...

Recently Titov et al [ApJ 693,(2009) and ApJ (2007)] have made use of a covariant model to investigate magnetic reconnection of astrophysical plasmas. Earlier R Ricca [Phys Rev A (1991)] has used another covariant formalism, to investigated vortex filaments and solitons. This formalism, called Ricci rotation coefficients (RRC), is applied here, to the Chui and Moffatt [PRSA (1995)] knotted magn...

In this work the main principles of radio resource sharing with UWB are stated. Specifically different possible network scenarios are considered and the relevant brought advantages are addressed in order to investigate and identify the most flexible network paradigm to exploit the advantages of UWB. Hence a model for the network architecture is proposed which is ad-ho oriented as well as able t...

We present V-band CCD photometry of 65 RR Lyr variables from the globular cluster M5. We have estimated the basic physical parameters for 16 RRc stars and 26 RRab stars using a Fourier decomposition of the light curves of the variables. The mean values of mass, luminosity, effective temperature and relative helium abundance for the RRc stars are measured to be M = 0.54 M ⊙ , log(L/L ⊙) = 1.69, ...

We discuss the largest and most homogeneous spectroscopic dataset of field RR Lyrae variables (RRLs) available to date. estimated abundances using both high-resolution low-resolution ({\Delta S} method) spectra for fundamental (RRab) first overtone (RRc) RRLs. The iron 7,941 RRLs were supplemented with similar literature estimates available, ending up 9,015 (6,150 RRab, 2,865 RRc). metallicity ...

This paper describes a deep reinforcement learning (DRL) approach that won Phase 1 of the Real Robot Challenge (RRC) 2021, and then extends this method to more difficult manipulation task. The RRC consisted using TriFinger robot manipulate cube along specified positional trajectory, but with no requirement for have any specific orientation. We used relatively simple reward function, combination...

The Fourier phase parameter ¢31 has been determined for RRc stars in five globular clusters NGC 6171 !"I 5, M.3, M?3, an~ M15. The results. indicate that the RRc. s!ars in a.given cluster show a seq~ence of ¢3: In~reasIn~ wIth penod, and that the hIgher !he cluster metalhclty, the higher the sequence lies in a plot of ¢31 wIth penod. The ¢31 values for the stars In NGC 6171 and M5 presented her...

Current LTE networks are experiencing significant growth in the number of users worldwide. The use data services for online browsing, e-learning, meetings and initiatives such as smart cities means that subscribers stay connected long periods, thereby saturating a signalling resources. One resources is Radio Resource Connected (RRC) parameter, which allocated to eNodeBs with aim limiting simult...
