The discrete-ordinates method is formulated to solve transient radiative transfer with the incorporation of a transient term in the transfer equation in two-dimensional rectangular enclosures containing absorbing, emitting, and anisotropically scattering media subject to diffuse and/or collimated laser irradiation. The governing equations resulting from the discrete-ordinates discretization of ...

Using slope enclosures may provide sharper bounds for the range of a function than using enclosures of the derivative. Hence, slope enclosures may be useful in verifying the assumptions for existence tests or in algorithms for global optimization. Previous papers by Kolev and Ratz show how to compute slope enclosures for convex and concave functions. In this paper, we generalize these formulas ...

Mariculture of tropical sea cucumbers is promising, but the nursery rearing of juveniles is a bottleneck for farming and sea ranching. We conducted four medium-scale experiments lasting 3-6 weeks, using thousands of cultured juvenile sandfish Holothuria scabra, to optimise nursery rearing in mesh enclosures in earthen seawater ponds and to test rearing in enclosures in the sea. In one experimen...

In this paper a parallel evolutionary algorithm (PEA) for coloring graph vertices is investigated. In the algorithm we apply a diffusion model of parallelism (DM). Evolutionary computations are performed in a regular mesh with either a constant size global population or a constant subpopulation in a single node. The performance of the PEA-DM is verified by computer experiments on standard DIMAC...

We describe a strategy for rigorous arbitrary-precision evaluation of Legendre polynomials on the unit interval and its application in the generation of Gauss-Legendre quadrature rules. Our focus is on making the evaluation practical for a wide range of realistic parameters, corresponding to the requirements of numerical integration to an accuracy of about 100 to 100 000 bits. Our algorithm com...

The shielding effectiveness (SE) measurements on enclosures with various apertures by both reverberation chamber (RC) and GTEM cell (GC) methodologies are presented. Furthermore, computer simulation through commercial software (CST) is used to compare with the experimental data. Our results show that the SE of the rectangular enclosure with five different apertures from RC is usually larger tha...

! , to occur in the function expression of the underlying function. Furthermore, we allow the function expression to contain functions given by two or more branches. By using interval arithmetic, second-order slope tuples provide verified enclosures of the range of the underlying function. We give some examples comparing range enclosures given by a second-order slope tuple with enclosures from ...

The most interesting feature discovered in Domasław’s burial ground is the ditched enclosures complex of a funeral character. oldest with ring trench was dated to middle Bronze Age (HaA2). This custom reaches its apogee early Iron (HaC). A total 26 chamber graves encircled by trenches, as well another ditch without probably also from this period, were cemetery. At end Early Age, practices withi...

Abstract Natural circulation loops are systems used to transport heat by the free convection of a working fluid in closed thermo-hydraulic circuit. Many examples Lattice Boltzmann method applied can be found literature, but most them limited model simple enclosures. This work is one first approaches an engineering system as Circulation Loops using this numerical method. study describes implemen...
