Melatonin affects a variety of circadian processes such as behavior and neurotransmitter release in vertebrates. Crayfish melatonin production occurs in the eyestalks, and the cycle of production may change seasonally. To date, however, melatonin's roles and mechanisms of action in crustacean physiology are unclear. We injected melatonin or saline into(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)
The purpose of this study is to provide a new method for detecting fetal QRS complexes from non-invasive fetal electrocardiogram (fECG) signal. Despite most of the current fECG processing methods which are based on separation of fECG from maternal ECG (mECG), in this study, fetal heart rate (FHR) can be extracted with high accuracy without separation of(More)

Distributed and dynamic nature of Grids causes the probability of failure is great in such systems. So fault tolerance has become a crucial area in computational Grid. In this paper, we propose a new Genetic Algorithm that used RFOH for having reliable job scheduling in computational Grid. This strategy maintains the fault occurrence history of resources in(More)
The paper addresses a new QRS complex geometrical feature extraction technique as well as its application for supervised electrocardiogram (ECG) heartbeat type classification. Toward this objective, after detection and delineation of major events of the ECG signal via an appropriate algorithm, each QRS region and also its corresponding discrete wavelet(More)
