4.1 Time step and spring constant For the integration time step the value of spring constant has often been reduced drastically several order of magnitude from the realistic ones without changing the macroscopic bed behavior as long as the maximum particle deformation remains small. Tsuji et al. [...
Data used in this work data were obtained from a single route (the Blue Loop) operated by the Centre Area Transportation Authority (CATA) in State College, PA for the time period between Spring 2013 and Fall 2014. All buses are equipped with Automatic Vehicle Location (AVL) and Automated Pa...
We spent a month in the preparation and planning of the shoot to ensure that we would be able to deliver the best results as well as address the ever evolving ideas. The spot was shot in the Mojave desert outside Los Angeles over a four day period and was as much fun to shot as it...
where m is lumped effective mass, c is damping coefficient of system, \(k_1\) is linear spring constant, \(k_3\) is nonlinear spring constant which controls dynamic behavior of the beam, \(\omega \) is driving frequency, F is harmonic force using the electrostatic drive. This higher-...
(i.e., early or late spring depending on the biome), characterized by a starch accumulation in plant organs lasting 51 days (average across biomes) (Fig.2). A second period (i.e., late spring or early summer depending on the biome), with low concentrations of soluble sugars, lasting...
For a function to be periodic, having a non-zero constant p, it should satisfy its definition : f(x+p) = f(x) This is the periodic function formula If this property is satisfied by any positive constant p, it is referred to as the fundamental period / primitive period. Hence, a fun...
Interestingly, the large drop in PA at age 10 and 15 years seems to coincide with a period of intense competitive exclusion between trees at this age, perhaps exacerbated by the relatively narrow tree spacing (2.5 × 2.5 m). The observed extent of PA for tree height was comparable with ...
