This study aims to determine the planting density and amount of fertilizers being suitable for growing, well-developed, high-yielding in Thua Thien Hue province. Research results shown that planting density and fertilization did not significantly affect the germination rate and growth time of sunflower in the winter crop season. The density did not affect the number of green leaves on the plant, the diameter of the calyx, the diameter of the flower, and the durability of flowers. At the fertilization level of 90 kg N + 60 kg P2O5 + 90 kg K2O per one hectare had the highest numbers of green leaves per plant and the diameter of calyx, flower diameter, and flower durability were highest. Planting density and fertilization had an interaction affect on the plant growth and yield. The largest stem diameter was at t...

Firstly, the analytical expressions of the system performance in term of outage probability (OP) and the system throughput (ST) are analyzed and derived in both amplify-and-forward (AF) and decode-and-forward (DF) modes. After that, we verify the correctness of the analytical analysis by using Monte-Carlo simulation in connection with the primary system parameters. From the numerical results, we can see that all the analytical and the simulation results are matched well with each other.

In this paper, we propose and investigate a Non-Orthogonal Multiple Access (NOMA) of energy harvesting (EH) relay assisted system over Block Rayleigh Fading Channel. In order to evaluate the performance of the proposed system, the integral expression of the outage probability is analyzed and derived. Numerical results confirm that our derived analytical results match well with the Monte Carlo simulations in connection with all possible system parameter.
