psychological and educational findings show that preschool years play a very important role in educating and developing children. one of the dimensions of development is motor development. the survey of motor performance with respect to anthropometric characteristic is of utmost importance. thus, the aim of this study was to survey the relationship between dimensional anthropometric characteris...

hydraulic jump on adverse stilling basin is an unstable phenomenon which causes some complexities in controlling of the   jump. this paper considers the stability of free hydraulic jump on adverse stilling basins from a theoretical point of view. a minimum value of upstream froude number is needed to produce the free hydraulic jump on adverse stilling basins which was presented by a theoretical...

In this work we consider the relation between the jump length probability density function and the line shape function in resonance radiation trapping in atomic vapors. The two-sided jump length probability density function suitable for a unidimensional formulation of radiative transfer is also derived. As a side result, a procedure to obtain the Maxwell distribution of velocities from the Maxw...

conclusions the he jump mat can be recommended in relation to the validity of constraints. in this study, only a part of the quality criteria were examined. for the final recommendation it is advised to examine the he jump mat on the other quality criteria (test-retest reliability, sensitivity change). background in the field of vertical jump diagnostics, force plates (fp) are the reference sta...

Forced hydraulic jump in a horizontal stilling basin with one and two continuous sills at the downstream end of an ogee standard weir was investigated. Experiments were completed on sills of five different heights which were fixed at two different distances from the toe of the weir. The main characteristics of the jump such as the sequent depth ratio, relative roller &#10length, and relative en...

background: physical exercises can influence some anthropometric and fitness components differently. the aim of present study was to evaluate how a relatively long‑term training program in 11‑14‑year‑old male iranian students affects their anthropometric and motor performance measures. methods: measurements were conducted on the anthropometric and fitness components of participants (n = 28) pri...

Quantum jump codes were introduced by Alber et al. (2001). Quantum jump codes have a close connection with combinatorial designs called t-SEED (t-spontaneaus emission error design). In this paper, we give a brief survey of a quantum jump code together with some new results. Firstly, fundamental properties of a terror correcting quantum jump code are described. Secondly, a few examples of jump c...
