Environmental pollution and emissions, along with the increasing production and distribution of goods, have placed the future of humanity at stake. Today, measures such as the extensive reduction in emissions, especially of CO2 and CO, have been emphasized by most researchers as a solution to the problem of environmental protection. This paper sought to explore production routing pro...

The cosmological vacuum, which is perfectly uniform, dominates by density over all the forms of cosmic matter. It makes the Universe be actually more uniform than it could be seen from the visible picture of the highly non-uniform matter distribution , especially inside the observed cell of uniformity (100 − 150 Mpc). This uniformity reveals itself in the structure of the Hubble matter flow whi...

Robust synchronization is indispensable for stable operation of a power grid. Recently, it has been reported that a large number of decentralized generators, rather than a small number of large power plants, provide enhanced synchronization together with greater robustness against structural failures. In this paper, we systematically control the spatial uniformity of the geographical distributi...

We study the multiply-with-carry family of generators proposed by Marsaglia as a generalization of previous add-with-carry families. We define for them an infinite state space and focus our attention on the (finite) subset of recurrent states. This subset will, in turn, split into possibly several subgenerators. We discuss the uniformity of the d-dimensional distribution of the output of these ...

This paper represents a new region-based active contour model that can be used to segment images with intensity non-uniformity and high-level noise. The main idea of our proposed method is to use Gaussian distributions with different means and variances with incorporation of intensity non-uniformity model for image segmentation. In order to integrate the spatial information between neighboring ...

Assessing how uniform the light distribution is throughout an illuminated target is important in many applications, but traditional methods do not quantify the variability of illuminance as the human visual system (HVS) does. Considering that most light patterns are intended for humans, I propose a simple metric that assesses the uniformity in a similar way as humans do. This uniformity indicat...

Field measurement results of the air slot type dipole magnet are presented. The vacant portion, called the air slot, located in the iron core controls the flow of the magnetic flux and improves uniformity of the magnetic field. This magnet realizes a better magnetic field distribution over a wide range of field strengths. The prototype of the magnet had been fabricated and tested to verify the ...

the non-uniformity factor is used for correction of the formulas obtained from the one-dimentional fluid flow method in a centrifugal impeller pump. the variations of radial velocity at the outlet of five centrifugal impellers with the specific speed of about ns =50 are calculated at design point by using two-dimentional potentional flow method for an invisid fluid. on the other hand~ the varia...

We have quantified the distribution of filament sizes and filament separation in internal Sn type Nb3Sn strand manufactured to ITER specification. In Nb-Ti strand for the SSC we had found a clear relationship between filament cross-sectional uniformity in a given cross-section and the n-value for an entire strand, but for the Nb3Sn we are not able to find one. In these Nb3Sn strands, however, t...

Reverberation chambers are commonly used in industry for measuring electromagnetic interference because they are cost-effective. We attempt to stir modes more evenly inside reverberation chambers by introducing passive field uniformity enhancement (PFUE) structures. These structures augment the existing rotating stirrers. Measured results for a 2.445 Х 2.475 Х 3.72 m reverberation chamber are p...
