Introduction: Acute myocardial infarction is one of the major causes of mortality in developing countries such as Iran. One of the most important progresses in acute myocardial infarction is early administration of therombolytic agents such as streptokinase. This study was performed to determine the time interval from patients’ referral to the emergency wards to the introduction of thrombolytic...

Unlike the existing views that was introduced the existence of delay caused by the transmission of wide area measurement system data (WAMS) into the controllers input of the power oscilation damping (POD) by communication networks as a reason for poor performance of the POD controllers. This paper shows that the presence of time delay in the feedback loop may improve the performance of a POD co...

Background: Delay in diagnosis and treatment of TB is a critical component in TB control program which thereby spreading illness in the community. Sicnce Golestan province has the high risk with high rates of tuberculosis in the country, therefore, the analysis of the factors associated with treatment delay in this province for effective interventions and proper planning is considered necessary...

This paper presents a digitally programmable delay line intended for use as timing generator in a RADAR ranging system. Traditional delay lines are realized selecting the delayed signal from a tap in a cascade of delay elements, resulting in a delay resolution limited by the matching errors between the delay elements. The architecture of the programmable delay line presented in this paper uses ...

Delay-based transmission control protocols need to separate round-trip time (RTT) measurements into their constituting parts: the propagation and the queueing delays. We consider two means for this; the first is to take the propagation delay as the minimum observed RTT value, and the second is to measure the queueing delay at the routers and feed it back to the sources. We choose FAST-TCP as a ...

This paper presents an ultra-wide-range all-digital delaylocked loop (DLL). The proposed DLL uses a novel delay circuit which uses the transistor’s leakage current in advanced CMOS process to generate a very large propagation delay. Thus, the proposed DLL can operate at very low frequency with small chip area and low power consumption. The proposed DLL can operate from 600 kHz to 1.2GHz in the ...

in this paper, a new t-s fuzzy hyperbolic delay model for a class of nonlinear systems with time-varying delay, is presented to address the problems of stability analysis and feedback control. fuzzy controller is designed based on the parallel distributed compensation (pdc), and with a new lyapunov function, delay dependent asymptotic stability conditions of the closed-loop system are derived v...

objective neurodevelopmental disability is one of the most common problems of children referred to  pediatric neurology clinics. these children may suffer from speech delay, intellectual deficiency and behavioral disorder. some patients with neurodevelopomental delay, especially those with intellectual disability and speech problems, have abnormal electroencephalograms, without clinical seizure...
