This paper analyzes the performance of unbuffered Delta networks under a nonuniform (“hot-spot”) traffic pattern. Particular attention is paid to characterizing the overflow traffic of unsuccessfully transmitted packets. Analytic techniques are used to show that the overflow traffic from an unbuffered packet-switched Delta network is (fractionally) hotter than the offered load. Simulation techn...

Neuropeptide Y (NPY) is a cotransmitter with norepinephrine (NE) and ATP in sympathetic nerves. There is evidence for increased activity of the sympathetic nervous system and the renin-angiotensin system (RAS), as well as a role for NPY in the development of hypertension in experimental animal models and in humans. Angiotensin II (ANG II) is known to facilitate sympathetic neurotransmission, an...

The present study was undertaken to look for the effect of chloroethylclonidine (CEC) on prejunctional alpha-2 autoreceptors of the canine saphenous vein. The effect was tested on tritium overflow evoked by electrical stimulation from tissues preloaded with 0.2 microM 3H-norepinephrine. Yohimbine (3-300 nM) and CEC (1-125 microM) increased and UK-14,304 reduced the overflow of tritium evoked by...

abstract weirs are the most common structures for discharge measurement in engineering research. streamline curvature, non hydrostatic pressure distribution on weir and nappe adherence to the weir lead to differences between calculated and measured discharges. thus discharge coefficient, which is the ratio of real and theoretic discharges, is usually less than unity. in circular weirs the press...

Simulation of large scale networks can be very time and resource-consuming. It is hard to predict when the amount of data collected from a simulation is enough and the measurement is accurate enough for the parameter of interest. In this paper, we study the planning of simulation run length, and investigate how many cycles of overflow / non-overflow are needed for the packet loss probability to...

A GI/G/1 queueing system with finite capacity il studied. The first overflow time, which means the time when the number of customers first exceeds the capacity, is analyzed by diffusion approximation. Approximate expressions for the distribution and moments of the first overflow time are derived explicitly. These results are modified so as to be more accurate for an M/G/I system or a system wit...

Motor overflow is extraneous movement in a limb not involved in a motor action. Typically, overflow is observed in people with neurological impairments and in healthy children and adults during strenuous and attention-demanding tasks. In the current study, we found that young infants produce vast amounts of motor overflow, corroborating claims of symmetry being the default state of the motor sy...

Multiple motor abnormalities have been identified in some children with Attention Deficit/Hyperactivity Disorder (ADHD). These include persistence of overflow movements, impaired timing of motor responses and deficits in fine motor abilities. Motor overflow is defined as co-movement of body parts not specifically needed to efficiently complete a task. The presence of age-inappropriate overflow ...

Overflow occurs when a value is represented in binary using an insufficient number of bits. Values that lie outside the bit range are misinterpreted as values within the bit range. Continuous signals that suffer from integer overflow can be correcting using unwrap functions, but this correction fails when significant noise is present. A new method of correcting signals is proposed which uses mo...
