In this paper, the complex conductivity including all Landau levels is calculated in a layered superconductor under magnetic field in the vortex liquid phase by using TDGL approach with thermal fluctuations modelled by the Langevin white noise. We obtain an expression summing all Landau levels in an explicit form. The rest of the paper is organized as follows. In section 2, the Lawrence-Donich model in its time dependent form is briefly recalled and the main assumptions are specified.

The time-dependent Ginzburg-Landau (TDGL) equation with thermal noise is used to calculate the complex fluctuation conductivity in high-Tc superconductor in three dimensional (3D) model at zero magnetic field. The nonlinear interaction term in the TDGL is treated within self-consistent Gaussian approximation we go beyond the often used lowest Landau level approximation.

The paper introduces an extension to a widely studied framework of opinion modelling, which adds agent mobility inspired by psychological and sociological studies. As described in Alraddadi et al. (2019), we evaluate and discuss the impact of different types of mobility on the nature of consensus that emerges. In addition, in this paper we have extended the model by incorporating noise in order to investigate robustness under uncertainty.

Junction temperature is the final temperature of any device, after that device became dead. In this paper, junction temperature of target device i.e. Pseudo Noise sequence random generator based optical transmitter is controlled using heat sink profile and airflow. Heat sink and airflow are the cooling techniques for thermal efficient design on FPGA. We operated target device at high speed transceiver logic (HSTL) on FPGA at 1, 10,100 and 1000 (GHz) operating frequency

We investigate effect of higher Landau levels on the transverse thermoelectric conductivity αxy, describing the Nernst effect in high-Tc superconductors, by using the time-dependent Ginzburg-Landau theory in two-dimensional model with thermal noise. The transverse thermoelectric conductivity is calculated in the self-consistent Gaussian approximation. Our results indicate that the contribution of higher Landau levels is less than that of lower Landau levels to the transverse thermoelectric conductivity. Our results are in good agreement with experimental data on high-Tc superconductor.

Thermal noise from optical coatings is a growing area of concern, and overcoming limits to the sensitivity of high-precision measurements by thermal noise is one of the greatest challenges faced by experimental physicists. In this timely book, internationally renowned scientists and engineers examine our current theoretical and experimental understanding. Beginning with the theory of thermal noise in mirrors and substrates, subsequent chapters discuss the technology of depositing coatings and state-of-the-art dielectric coating techniques used in precision measurement.

Digital images and video, acquired by still cameras, consumer camcorders, or even broadcast-quality video cameras, are usually degraded by some amount of blur and noise. In addition, most electronic camerashavelimitedspatial resolutiondeterminedbythecharacteristicsof thesensorarray. Common causes of blur are out-of-focus, relative motion, and atmospheric turbulence. Noise sources include filmgrain, thermal, electronic, and quantization noise.
