Robust time series analysis for forecasting photovoltaic energy yield [PDF]

E3S Web of Conferences
This study introduces an approach to forecasting the power output of a photovoltaic (PV) system by employing an ARIMA-based algorithm. Two distinct ARIMA models were designed – one generated via SPSS and one selected by the researchers.

Parallel Algorithm Configuration [PDF]

, 2012
State-of-the-art algorithms for solving hard computational problems often expose many parameters whose settings critically affect empirical performance. Manually exploring the resulting combinatorial space of parameter settings is often tedious and unsatisfactory.

Parallelization of the IDEA Algorithm [PDF]

, 2004
In this paper, we present results of parallelizing the International Data Encryption Algorithm (IDEA). The data dependence analysis of loops was applied in order to parallelize this algorithm. The OpenMP standard is chosen for presenting the parallelism of the algorithm. The efficiency measurement for a parallel program is presented.

Second-Order L1 Schemes for Fractional Differential Equations

Fractal and Fractional
Difference schemes for the numerical solution of fractional differential equations rely on discretizations of the fractional derivative. In this paper, we obtain the second-order expansion formula for the L1 approximation of the Caputo fractional ...
