In this paper, as an application in biometrics, the electrical capacitance of normal and cancerous blood samples is experimentally determined in order to test the null hypothesis that the electrical capacitance of the two samples differs. The samples taken from healthy donors and patients diagnosed with different types of hematologic cancer are examined by a cylindrical capacitor with blood as its dielectric. The capacitance of these samples is measured at room temperature and a single frequency of 120 Hz, well below the frequency where β-dispersion starts, using a simple LCR meter device. The measurements indicate that the capacitance of the blood increases under applied electric field for... 

Treatment of cancer involves many invasive procedures that could be a source of distress in kids suffering from cancer. Distress itself can be an important obstacle in patients' acceptance of treatment and their adaptation to it, consequently reducing its efficiency. Distress symptoms, in a spectrum from mild to critical, are shown to be widespread in children struggling with cancer. In recent years to alleviate this psychological condition, researchers have proposed and examined several methods such as relaxation, hypnosis, desensitization, and distraction. This study presents a new approach to explore the impact of utilizing a humanoid robot as a therapy-assistant in dealing with patients'...
