Over two decades, a problem of location dependent has been focused for improving the communication Bandwidth-Power Efficiency of homogeneous networks. The efficiencies of communication links are weakened by the Hidden Terminal Problem.  Thus we propose a Fine – Tune Strategy for analyzing the On-Off communication region. We were observed that the proposed technique had been able to track and mo...

Fast Congestion Notification (FN) is one of the proactive queue management mechanisms that practices congestion avoidance to help avoid the beginning of congestion by marking/dropping packets before the router’s queue gets full; and exercises congestion control, when congestion avoidance fails, by increasing the rate of packet marking/dropping. Technically, FN avoids the queue overflows by cont...

The aim of the present study was to identify the total drop-out rate and drop-out reasons for a group of promising track and field athletes. 202 males and 98 females, aged 16 ±2 years, took part in this study. Questionnaires were administrated in 1975, 1983, and 1989. In-depth interviews were conducted in 1989 and in 2000. A chi-square test was administrated to test the difference between males...

We consider the problem of efficiently and fairly allocating bandwidth at a highly congested link to a diverse set of flows, including TCP flows with various Round Trip Times (RTT), non-TCP-friendly flows such as Constant-Bit-Rate (CBR) applications using UDP, misbehaving, or malicious flows. Though simple, a FIFO queue management is vulnerable. Fair Queueing (FQ) can guarantee max-min fairness...

This paper proposed a preferential dropping algorithm and a tagging algorithm. The proposed twin RIO algorithms use two sets of parameters, one set for in packets and one for out packets. As in RED, RIO has three phases to determine dropping in the routers, normal operation, congestion avoidance and congestion control. The paper designed a TSW tagger, which is a profile meter for bulk-data tran...

KEY FINDINGS Monitoring sexual activity and contraceptive use among U.S. adolescents is important for understanding differences in their risk of pregnancy. In 2013, the U.S. birth rate for teenagers aged 15-19 dropped 57% from its peak in 1991 (1), paralleling a decline in the teen pregnancy rate (1-2). But these rates are still higher than those in other developed countries (3-4). Using data f...

This user study investigated how rendering quality contributes to the sense of presence and level of task performance of participants in a virtual environment. Fiftyfive participants performed the task of dropping four objects in a two-room, virtual environment which was drawn with varying degrees of texture and lighting quality. Their physiological reactions were measured along with their accu...
