Background. The EORTC IN-PATSAT32 questionnaire was developed by the EORTC Quality of Life (QL) Group to assess the satisfaction of patients affected by cancer and hospitalized in oncology centers. The aim of this study is to assess the psychometric properties of the EORTC IN-PATSAT32 administered to Moroccan patients. Methods. A total of 133 hospitalized patients affected by cancer in differen...

BACKGROUND Quality of life (QOL) improvement is the main objective of treating patients with irritable bowel syndrome (IBS). This study aimed to assess the validity, reliability, and factor analysis of IBS-QOL-34 questionnaire as a common transcultural instrument for Iranian IBS patients. MATERIALS AND METHODS Two hundred and forty patients with IBS (based on gastroenterologists' diagnosis ac...

When the goal is to achieve the best correct classification rate, cross entropy and mean squared error are typical cost functions used to optimize classifier performance. However, for many real-world classification problems, the ROC curve is a more meaningful performance measure. We demonstrate that minimizing cross entropy or mean squared error does not necessarily maximize the area under the ...

BACKGROUND Men, much like women, are faced with age-related menopause-like symptoms as they age. In recent years, increasing attention has been drawn to clinical research into elderly men and their health-related quality of life. The Aging Male Scales (AMS) questionnaire is an international tool for assessing the health-related quality of life in elderly men. Hence far this questionnaire has no...

BACKGROUND Infertility and its treatment can have a considerable effect on a person's quality of life (QoL). The Fertility QoL (FertiQoL) questionnaire is currently the most frequently used instrument to measure QoL in people with fertility problems. This study aims to examine the reliability and validity of the FertiQoL in infertile Iranian women. MATERIALS AND METHODS This cross-sectional s...

--Image Quality assessment plays an important role in various image processing applications. It is still an active area of research. A great deal of effort has been made in recent years to develop objective image quality metrics that correlate well with perceived human quality measurement or subjective methods. Most full reference(FR) technique were derived based on pixel to pixel error such as...

This study aims to present an adaptive audio watermarking method using ideas of wavelet-based entropy (WBE). The method converts low-frequency coefficients of discrete wavelet transform (DWT) into the WBE domain, followed by the calculations of mean values of each audio as well as derivation of some essential properties of WBE. A characteristic curve relating the WBE and DWT coefficients is als...

Future communication networks would be required to deliver data on a far greater scale than is known to us today, thus mandating the maximal utilization of the available radio spectrum using cognitive radios. In this paper, we have proposed a novel cooperative spectrum sensing approach for cognitive radios. In cooperative spectrum sensing, the fusion center relies on reports of the cognitive us...

Many performance metrics have been introduced in the literature for the evaluation of classification performance, each of them with different origins and areas of application. These metrics include accuracy, macro-accuracy, area under the ROC curve or the ROC convex hull, the mean absolute error and the Brier score or mean squared error (with its decomposition into refinement and calibration). ...
