Comparison Between Ordinary Methods (LS,IV) and Robust Methods (2SWLS,LTS,RA) to estimate the Parameters of ARX(1,1,1) Model for Electric Loads
...Show More Authors

 

Abstract:

The models of time series often suffer from the problem of the existence of outliers ​​that accompany the data collection process for many reasons, their existence may have a significant impact on the estimation of the parameters of the studied model. Access to highly efficient estimators  is one of the most important stages of statistical analysis, And it is therefore important to choose the appropriate methods to obtain good  estimators. The aim of this research is to compare the ordinary estimators and the robust estimators of the estimation of the parameters of the Autoregressive with exogenous variable (ARX) model with the order of (1,1,1) using real data containing outliers, the order (1,1,1) has been used based on a number of criteria for determining the rank, which were explained in the thesis under construction. The study showed that the method employed The Least Trimmed Squares (LTS) method is the best method of estimation. The comparison was done using the Root Mean Square Error (RMSE), Mean Absolute Percentage Error (MAPE) and Expected Error Percentag (EEP), A test was also carried out to ascertain the accuracy of the model reached and then used to predict future values.

Retina Based Glowworm Swarm Optimization for Random Cryptographic Key Generation
...Show More Authors

The biometric-based keys generation represents the utilization of the extracted features from the human anatomical (physiological) traits like a fingerprint, retina, etc. or behavioral traits like a signature. The retina biometric has inherent robustness, therefore, it is capable of generating random keys with a higher security level compared to the other biometric traits. In this paper, an effective system to generate secure, robust and unique random keys based on retina features has been proposed for cryptographic applications. The retina features are extracted by using the algorithm of glowworm swarm optimization (GSO) that provides promising results through the experiments using the standard retina databases. Additionally, in order t
