This paper reviews different encoding schemes for reduction of power dissipation, crosstalk noise and delay. Crosstalk is aggravated by enhanced switching activity which is often main cause for the malfunctioning of any VLSI chip. Consequently, delay and power dissipation also increases due to enhanced crosstalk. Reduction in switching activities through coupled transmission line results in eno...

The loading of web servers can be very heavy and a delay in accessing certain Web sites can be substantial. Hence, the reduction of web delay is one of the important topics of research for improving the quality of service of Web pages. Thus, in this paper, we propose the web delay analysis and the web delay reduction by using load balancing coupled with the dispatcher-based approach. First, we ...

designing wireless sensor networks should meet appropriate parameters such as quality of service (qos) defined by different users. the variable physical conditions of the environment, processing and transmission power limitations and limited communication capabilities are the most important obstacles that influence qos parameters such as throughput, delay, reliability and network lifetime. the ...

Speed reduction strategies have proved to be useful to recover delay if air traffic flow management regulations are cancelled before initially planned. Considering that for shorthaul flights the climb and descent phases usually account for a considerable percentage of the total trip distance, this paper extends previous works on speed reduction in cruise to the whole flight. A trajectory optimi...

Air Traffic Flow Management (ATFM) regulations, such as ground holdings, are often cancelled before their initially planned ending time. This early cancellation leads to an unnecessary ground delay and a misuse of airport or airspace resources. In previous publications, the authors have suggested a speed reduction strategy aiming at splitting the assigned ATFM delay between ground delay and air...

Balanced truncation is a standard and very natural approach to approximate dynamical systems. We present a version of balanced truncation for model order reduction of linear time-delay systems. The procedure is based on a coordinate transformation of the position and preserves the delay structure of the system. We therefore call it (structure preserving) position balancing. To every position we...

A method is presented to divide the measured total congestion in any freeway section into three ‘slices’: (1) the delay that collisions cause; (2) the potential reduction in delay at bottlenecks that ideal ramp metering can achieve; and (3) the remaining delay, due mainly to excess demand, but also to all other causes, including non-collision incidents, lane closures, and weather. The method in...

STUDY OBJECTIVE To measure the pre-hospital delay times in patients with proven acute myocardial infarction (AMI) and to identify possibilities for reduction of treatment delay. DESIGN Descriptive three centre study. SETTING One university teaching hospital and two regional hospitals in Groningen, the Netherlands. PATIENTS 400 consecutive confirmed AMI patients, age below 75 years, admitt...

In mobile terminals speech quality is often degraded by acoustic echo and noise. Existing approaches to tackle these problems involves separated solutions. However, combined solution have been proposed recently. Low signal delay and reduced computational load are the main arguments in favor of joint noise and echo processing. Most such algorithms operate in the frequency domain. In recent works...
