In this work, we consider the coupled systems of linear unsteady partial differential equations, which arise in the modeling of poroelasticity processes. Stability estimates of weighted difference schemes for the coupled system of equations are presented. Approximation in space is based on the finite element method. We construct splitting schemes and give some numerical comparisons for typical ...

We present Aidloc, an acoustic indoor localization system based on acoustic ranging which is very convenient for smartphone positioning. An Aidloc demo system consists of 5 acoustic beacons and a smartphone. Beacons are deployed in different hight to establish a beacon space. This gives a 3D relative coordinate for 3D target localization. A combined localization approach of TDOA and TOA is used...

We have computed a grid of chemical evolution models for a large set of spiral and irregular theoretical galaxies of different total mass. In our models, the gas phase has two components, the diffuse and the molecular one (H2). It is possible, therefore, to follow the time (or redshift) evolution of the expected density of the H2 phase. We will show the predictions of this gas density at hight ...

Background Prevalence of obesity in children and adolescent has significantly increased, it becomes a serious problem because of the overreleasing of interleukin-6 (IL-6), disruption on the oxidative balance, risk factor of getting cardiovascular disease with typically marked by elevation of the hight sensitivity C-Reactive Protein (hsC-RP). On the way to decrease IL-6 release from the visceral...

9 To provide stable and high data rate wireless access for passengers in the train, it is necessary to 10 properly deploy base stations along the railway. We consider this issue from the perspective of service, 11 which is defined as the integral of the time-varying instantaneous channel capacity. With large-scale 12 fading assumption, it will be shown that the total service of each base statio...
