Improving prediction performance of stellar parameters using functional models

Improving the performance of financial forecasting using different combination architectures of ARIMA and ANN models

Despite several individual forecasting models that have been proposed in the literature, accurate forecasting is yet one of the major challenging problems facing decision makers in various fields, especially financial markets. This is the main reason that numerous researchers have been devoted to develop strategies to improve forecasting accuracy. One of the most well established and widely use...

Improving the GPU performance prediction models to design space exploration

Recently, GPUs have also been used plenty in the scientific calculations for high-performance in parallel computing power and low energy consumption. Offering GPU performance prediction models base on Micro-architecture parameters to optimal design in the hardware process of the GPU, has been the subject of prior works. In this article, we defined design space NVIDIA Fermi GPU bigger than the p...

Relativistic Stellar Models with Quadratic Equation of State

In this paper, we have obtained and presented new relativistic stellar configurations considering an anisotropic fluid distribution with a charge distribution and a gravitational potential Z(x) that depends on an adjustable parameter. The quadratic equation of state based on Feroze and Siddiqui viewpoint is used for the matter distribution. The new solutions can be written in terms of elementar...

Performance Prediction in Cycling Using Antagonistic Models

Two antagonistic models are used to model the training-performance relationship during an eight week cycling training, with a prediction of the performances in the last week of training. Results indicated different qualities of the model fits for the test data for both models. Mean differences between predicted and real performances were 2.39% for the Fitness-Fatigue-Model and 4.43% for the Per...
