In this paper, bit error performance evaluation of chaotic sequences is presented. Performance of chaotic sequences is evaluated on multiple access spread spectrum system model for USRP software defined radio. LabVIEW is used to perform numerical simulations and bit error rate analysis. Chaotic sequences of different lengths are generated using one-dimensional, two-dimensional, and three-dimens...

It is more common for educational and psychological data to be non-normal than to be approximately normal. This tendency may lead to bias and error in point estimates of the Pearson correlation coefficient. In a series of Monte Carlo simulations, the Pearson correlation was examined under conditions of normal and non-normal data, and it was compared to its major alternatives, including the Spea...

planned human resource development is critical to educating a skilled and efficient workforce. the present study aimed at identifying the main factors of planned human resource development in iranian social security organization hospitals. the study is done through analysis of a questionnaire designed after identification of the main variables. iran social security organisation hospitals (the m...

BACKGROUND Currently, the longitudinal validity (validity over time) and responsiveness (ability to measure change over time) of the Food Allergy Quality of Life Questionnaire-Adult Form (FAQLQ-AF), the Food Allergy Quality of Life Questionnaire-Teenager Form (FAQLQ-TF), and the Food Allergy Quality of Life Questionnaire-Child Form (FAQLQ-CF) are unknown. Additionally, the self-reported impact ...

Background. Protein dihedral angles provide a detailed description of protein local conformation. Predicted dihedral angles can be used to narrow down the conformational space of the whole polypeptide chain significantly, thus aiding protein tertiary structure prediction. However, direct angle prediction from sequence alone is challenging. Method. In this study, we present a novel method to pre...

A Collaborative Filtering was successfully implemented using the computer programming language Java to produce recommendations between users such that only similar users were considered. Both Mean Squared Difference (MSD) and Pearson Correlation Coefficient (PCC) were used and evaluations carried out on each. The metric which performed best on the u.data file was PCC with L = 0. Conversely, the...

BACKGROUND Assessment of treatment response by measuring tumor size is known to be a late and potentially confounded response index. Serial diffusion MRI has shown potential for allowing earlier and possibly more reliable response assessment in adult patients, with limited experience in clinical settings and in pediatric brain cancer. We present a retrospective study of clinical MRI data in chi...
