In this study, we have introduced an open-source program that can be used for the detection and analysis of different waves in the ECG signal. The effect of noise is first reduced by applying an adaptive least-squares method to the signal using a sliding window. The maximums and minimums of the signal are determined, and the R-waves are then detected using(More)
Congestion occurs in wireless sensor networks (WSNs) when nodes are densely distributed, and/or the application produces high flow rate near the sink due to the convergent nature of upstream traffic. Congestion can lead to packet losses, delay, and energy waste due to a large number of packet drops and retransmissions. Therefore it is necessary to carry out(More)
Nowadays, car following models, as the most popular microscopic traffic flow modeling, are increasingly being used by transportation experts to evaluate new Intelligent Transportation System (ITS) applications. This paper presents a car-following model that was developed using an adaptive neuro fuzzy inference system (ANFIS) to simulate and predict the(More)
The control of car following is essential to its safety and its operational efficiency. For this purpose, this paper builds a linear, continuous and time-delay model of car following. And then, presents a controller based on an adaptive network fuzzy inference system (ANFIS) for the car-following collision avoidance system to adaptively control the speed of(More)
Reliable event detection at the sink is based on collective information provided by source nodes and not on any individual report. Reliable data gathering and transmission are important in wireless sensor networks. While node redundancy in WSNs, increases the fault tolerance, no guarantees on reliability levels can be assured. Furthermore, the frequent node(More)
OBJECTIVE To evaluate the effectiveness of cyclophosphamide and methylprednisolone pulse therapy in the prevention of pulmonary fibrosis due to paraquat poisoning in rats. METHODS This study was carried out in Sina Hospital, Tabriz, Iran, between February and August 2009. Acute poisoning in rats was induced by intraperitoneal injection of Paraquat (15(More)
In this study, a mathematical model is developed based on algebraic equations which is capable of generating artificially normal events of electrocardiogram (ECG) signals such as P-wave, QRS complex, and T-wave. This model can also be implemented for the simulation of abnormal phenomena of electrocardio-graphic signals such as ST-segment episodes (i.e.(More)
