[1] A series of flume experiments were conducted to study the effect of bed form dynamics on the flow over a gravel bed comprising a wide distribution of grain sizes. Instantaneous high‐frequency streamwise flow velocities were sampled using an acoustic Doppler velocimeter at a frequency of 200 Hz, while the simultaneous bed elevations were sampled using sonar transducers at a frequency of 0.2 ...

Leaf-cutting ants (Atta spp.) create physical pathways to support the transport of resources on which colony growth and reproduction depend. We determined the scaling relationship between the rate of resource acquisition and the size of the trail system and foraging workforce for 18 colonies of Atta colombica and Atta cephalotes. We examined conventional power-law scaling patterns, but did so i...

The cardiovascular system is an apparatus of mass convection, and changes in organismic size impart variables this system, namely scaling effects. Blood flow depends on pressure conductance, the maintenance results entropy production, that is, loss available work. In terms scaling, it well known blood kept constant while volume varies linearly with body mass. Yet, such expected rules have never...

We describe MPSE: a Multi-Perspective Simultaneous Embedding method for visualizing high-dimensional data, based on multiple pairwise distances between the data points. Specifically, MPSE computes positions points in 3D and provides different views into by means of 2D projections (planes) that preserve each given distance matrices. consider two versions problem: fixed variable projections. with...

We consider kernel estimation of marginal densities and regression functions of stationary processes. It is shown that for a wide class of time series, with proper centering and scaling, the maximum deviations of kernel density and regression estimates are asymptotically Gumbel. Our results substantially generalize earlier ones which were obtained under independence or beta mixing assumptions. ...

According to the process scaling, radiation-hard devices are becoming sensitive to soft errors caused by Multiple Cell Upset (MCUs). In this paper, the parasitic bipolar effects are utilized to suppress MCUs of the radiation-hard dual-modular flip-flops. Device simulations reveal that a simultaneous flip of redundant latches is suppressed by storing opposite values instead of storing the same v...

The goal of the DIII–D program is to provide the integrated basis for commercially attractive steady state fusion power plants. Significant progress toward this goal has been achieved, enabled by system improvements including an error field correction coil, an expanded diagnostic set, a digital plasma control system, and high power rf systems. Simultaneous improvements in both the confinement a...

This paper presents results on the typical number of simultaneous point-to-point transmissions above a minimum rate that can be sustained in a network with n transmitter-receiver node pairs when all transmitting nodes can potentially interfere with all receivers. In particular we obtain a scaling law when the fading gains are independent Rayleigh distributed random variables and the transmitter...

Measurement of soil saturated hydraulic conductivity, Ks, is normally affected by flow patterns such as macro pore; however, most current techniques do  not differentiate flow types, causing major problems in describing water and chemical flows within the soil matrix. This study compares eight models for scaling Ks and predicted matrix and macro pore Ks, using a database composed of 50 datasets...

Hans Bremermann was one of the pioneers of evolutionary computation. Many of his early suggestions for designing evolutionary algorithms anticipated future inventions, including scaling mutations to be inversely proportional to the number of parameters in the problem as well as many forms of recombination. This paper explores the gain in performance that occurs when Bremermann’s original evolut...
