Advection-diffusion model for the simulation of air pollution distribution from a point source emission

Wahidin, Wahidin

Advection-diffusion model is one of the mathematical models, which can be used to understand the distribution of air pollutant in the atmosphere. It uses the 2D advection-diffusion model with time-dependent to simulate air pollution distribution in order to find out whether the
pollutants are more concentrated at ground level or near the source of emission under particular atmospheric conditions such as stable, unstable, and neutral conditions. Wind profile, eddy diffusivity, and temperature are considered in the model as parameters. The model is solved by using explicit finite difference method, which is then visualized by a computer program developed using Lazarus programming software. The results show that the atmospheric conditions alone influencing the level of concentration of pollutants is not conclusive as the parameters in the model have their own effect on each atmospheric condition.

Improving Performance and Size Reduction of Truncated Microstrip Antenna Using U Slot for LTE Application

Alam, Syah

This paper proposed new design of truncated microstrip antenna with U slot for LTE application at work frequency of 2300 MHz. The addition of slot with U shape aims to reduce return loss and VSWR from antenna, beside that giving U slot also can reduce the dimension of antenna to be more compact. The proposed antenna have been design. The proposed antenna, designed and realized using a FR4 Epoxy substrate with a dielectric constant (εr) of 4.3, a thickness (h) of 1.6 mm and a loss tan (tan α) of 0.0265 . From the measurement result obtained return loss of -22.95 dB and VSWR of 1.1.5 at working frequency of 2300 MHz with bandwidth of 250 MHz (2100 -2350 MHz). The addition of U slot has been successfully improved the value of return loss until 43 % and VSWR until 15 % compared with truncated microstrip antenna without U slot. Beside that, the dimension of microstrip antenna have been reduced until 17.87 % after using U slot.
