In wireless sensor networks, it is crucial to support the collected data of sensor nodes with position information. One of the promising ways to acquire the position of unknown nodes is using a mobile anchor node that traverses throughout the network, stops at determined points, and sends its position to aid in obtaining the location of other unkno...

Nowadays, there are millions of people around the world suffer from the disability caused by big stroke. In recent years we have seen a rising interest in brain computer interface (BCI) systems that help those patients to practice their normal lives. Therefore, this work presents a GUI application based on an offline BCI system to test their mental...
Conference Paper
Full-text available
Classification of EEG signals is one of the biggest problems in Brain Computer Interface (BCI) systems. This paper presents a BCI system based on using the EEG signals associated with five mental tasks (baseline, math, mental letter composing, geometric figure rotation and visual counting). EEG data for these five cognitive tasks from one subject w...

This paper provides a new technique of multi-sensor data fusion to achieve an optimal spatial design and power operation of integrated Renewable Energy Grids (REG). This new approach depends on making a sensor data fusion system depending on the spatial concepts for measuring the important climate parameters, which have a great effect on the perfor...
Conference Paper
Iris recognition is one of the most reliable biometric technologies. In order to improve the accuracy of iris recognition systems, and according to the variations in iris data, due to noises of the eyelids and eyelashes or inappropriate image acquisition environment, multiple iris images per person are enrolled. Therefore, these systems suffer from...

Clusters of microcalcifications in mammograms are an important early sign of breast cancer in women. Comparing with microcalcifications, the breast background tissues have high local self-similarity, which is the basic property of fractal objects. A fast fractal modeling method of mammograms for detecting the presence of microcalcifications is prop...
