Recently, ParaExp was proposed for the time integration of linear hyperbolic problems. It splits the time interval of interest into sub-intervals and computes the solution on each sub-interval in parallel. The overall solution is decomposed into a particular solution defined on each sub-interval with zero initial conditions and a homogeneous solution propagated by the matrix exponential applied...

In this paper we investigate the effects of the asynchronism of user signals in the uplink of a spread spectrum multi-carrier multiple access (SS-MC-MA) system. Different propagation delays due to different distances between the mobile transmitters and their base station cause asynchronous arrivals of the uplink signals in addition to multipath propagation. The proposed uplink SS-MC-MA scheme u...

The low conversion efficiency of solar cells produces large amounts of thermal energy to the cells, and with an increase in the temperature of solar cells, their electrical efficiency decreases. Therefore, a hybrid photovoltaic thermal system improves the overall efficiency of the system by adding thermal equipment to the solar cell and removing excessive heat from these cells. In this paper, w...

This study measures the efficiency of energy consumption in residential sector Slovenia. It extends existing research on estimation electricity by considering multiple sources used households. The detailed disaggregated data from two cross-sectional surveys conducted years 2010 and 2014, resulting a sample 6882 Slovenian households, is estimation. includes services stochastic frontier framework...

The present work evaluates the performance of solar collector using Al2O3-C2H6O2-H2O nanofluid as a working fluid through both experimental and CFD analysis. Ethylene-glycol water mixture (40:60 v/v) is used as base fluid, where α-Al2O3 nanoparticle of 20 nm average size is dispersed for the preparation of nanofluid of four different volumetric concentration (vol. conc.) of 0.05, 0.075, 0.1 and...

background and objectives: nowadays herbicide reduction and different approaches leading to this goal like split application have been brought to attention. at split application, recommended or reduced doses divided in such a way which half of dose applied at one growth stage and the other half will use at next growth stage and finally all used doses are equal to recommended or any other reduce...
