In this thesis, we propose an improved exchange rate forecasting model based on neural network, stationary wavelet transform and statistical time series analysis techniques. We compare the new model's performance with pure neural network forecasting model, wavelet/wavelet-packet-denoising-based forecasting models and the methods used in nine previous(More)
As the rates of market change accelerate and customer expectations grow, product development becomes an increasingly important activity. In this environment, the performance of the product development process and the impact of product design on costs are critical factors for organizational success. To respond, firms are adding resources such as(More)
Here three subwavelength multiband receiving antennas have been designed using corrugated ring resonator printed on a thin dielectric substrate with spiral-shaped defect ground structure (DGS). Numerical simulations verified that these multiband antennas have multiband with a small size of only 0.1λ*0.1λ. In addition, a 2*2 antenna array has(More)
Specific to the maximization of the system throughput, the joint resource allocation schemes for Device-to-Device (D2D) communication are proposed. Another purpose of the joint resource allocation schemes is to avoid the strong interference between cellular communication and the D2D communication. The core strategy of the algorithm is to establish a(More)
