[ 1 ] - تخمین بدون کاف فشارخون مبتنی بر ویژگیهای زمانی سیگنال نبض
Blood pressure is one of the vital signs. Specially, it is crucial for some cases such as hypertension patients and it should be monitored continuously in ICU/CCU. It must be noted that current systems to measure blood pressure, often require trained operators. As an example, in post-hospital cares, blood pressure control is difficult except with the presence of a nurse or use of a device that ...
[ 2 ] - Design and Implementation of an Automated Dispensing Device for Reducing Methadone Therapy Misuse
Introduction: A variety of (deliberate or inaccurate) errors in drug rehabilitation clinics may occur due to use of addictive drugs. Automated drug distribution systems play a significant role in reducing drug medication errors. Method: Firstly, according to the addiction rehabilitation centers requests, the design and construction of the device was performed. The prototype systems were examin...
[ 3 ] - Optimized Blood Volume Monitoring during Hemodialysis Procedure based on Ultrasonic Speed Measurement
Fast reduction of blood water volume due to ultra-filtration via hemodialysis machine and critical threshold of blood water volume can result in clinical complications such as hypotension. When blood water volume reduces during hemodialysis process, the concentration of blood forming elements will increase. One of the methods for the monitoring of the concentration changes is ultrasonic speed m...
[ 4 ] - Classification of EEG Signals for Discrimination of Two Imagined Words
In this study, a Brain-Computer Interface (BCI) in Silent-Talk application was implemented. The goal was an electroencephalograph (EEG) classifier for three different classes including two imagined words (Man and Red) and the silence. During the experiment, subjects were requested to silently repeat one of the two words or do nothing in a pre-selected random order. EEG signals were recorded by ...
