Density fluctuations in traffic current are studied by computer simulations using the deterministic coupled map lattice model on a closed single-lane circuit. By calculating a power spectral density of temporal density fluctuations at a local section, we find a power-law behavior, ∼ 1/f, on the frequency f , in non-congested flow phase. The distribution of the headway distance h also shows the ...

During the COVID-19 lockdown prolonged closure of sport facilities is causing Legionella growth in system. Based on an in-house developed simulation tool, L. pneumophila concentration predicted dynamically throughout system and restart guidelines are evaluated.

For a given bounded connected domain in IR, the issue of computing the observability constant associated to a wave operator, an observation time T and a generic observation subdomain constitutes in general a hard task, even for one-dimensional problems. In this work, we introduce and describe two methods to provide precise (and even sharp in some cases) estimates of observability constants for ...

For high speed wireless communication, data are transmitted with high spectral efficiency, high data rate and reliability. But due to Rayleigh fading, the channels suffer from lot of attenuation resulting in the reduction of Energy Efficiency (EE) and Spectral Efficiency (SE). The proposed system consists of MIMO using Closed Form Approximation (CFA) method. Multiple input Multiple Output (MIMO...
