Abstract:

An isotopic fission yield calculation method for fast energy spectrum of neutron has been proposed. This method was derived from a systematic of fission mass yield and a nuclei decay probability. The decay probability was calculated from the level density parameters that derived from a new potential function in combining with the shell correction. The potential function is a modified Wood-Saxon potential that we have called as an extended-Wood-Saxon potential. We have employed the data from RIPL-2 (Reference Input Parameter Library-2) in calculating the level density parameter. The calculation

The limit state of circular arches of constant and variable stiffness is considered. The material of the arches is elastic-plastic and has different yield points in tension and compression. The reinforcement of the section is also taken in the form of an elastic-plastic material with the same yield points in tension and compression. The use of two factors in the calculations is considered - longitudinal force and bending moment. To determine the ultimate load, the limit equilibrium method is used with the involvement of the strength region of the cross-section of the arch. The strength region

Application of The Torsion Test in Calculating The Extrusion ForceThe paper deals with the calculation of the extrusion force using the results of the torsion test of aluminium alloy EN AW-2014. The mathematical model for the calculation of the extrusion force requires the knowledge of the functional relationship between the yield stress and the temperature, the deformation and the deformation rate. Based on the proposed mathematical model for the calculation of the yield stress, the functional relationship was derived to determine the extrusion force in the hot extrusion of semi-products of a

In the design of steel structures, the main value of the steel elements in the yield strain point is taken into account in the calculations. Over time, corrosion occurs on steel structures, indicating a negative influence. When a steel element is subjected to corrosion in a particular corrosion category, its mechanical properties change. Although there are many studies in the field of change, there is no uniform formula or equation that can be used to calculate the possible change in the value on yield strain.

In order to derive the burnup of spent nuclear fuel from the concentration of selected fission products (typically the Nd isotopes and 137Cs), their irradiation-averaged fission yields need to be known with sufficient accuracy, as they evolve with the changes in the actinide vector over the irradiation history. To obtain irradiation-averaged values, radiochemists often resort to robust generic methods – i.e., based on simple mathematical relations – that weight the fission yields according to the actinides contributing to fission, without performing core physics calculations.

Abstract:

The programming (simulation) of yield in the area of “risky farming” that Belarus belongs to according to data from a single-factor experiment considering only the food mode, can lead to unacceptably large errors in the calculations. These errors can easily be avoided by increasing the factorality of agronomic experiment by using standard meteorological data processed using mathematical model of crop yields. A mathematical model of environmental factors effect on crop yields is proposed and tested. It is shown that the accuracy of yield simulation (calculation) increases with the growing numbe

Abstract:

The axial compressive experiments were carried out on 21 welded composite T-shaped concrete-filled steel tubular columns, and 395 finite element models were established for parameter calculation. The calculating formula of axial compressive bearing capacity of welded composite T-shaped concrete-filled steel tubular columns is established. The results show that three typical failure modes were found: middle buckling, end local buckling, and integral bending. When the slenderness ratio λ exceeds the elastic instability limit λp, the axial stress of steel is lower than yield strength fy, and the

Abstract:

One of the most important diseases of wheat in Turkey is yellow rust. The severe epidemic in the 1997–1998 growing season, which caused significant yield reductions, and the absence of infection at the Hamidiye Substation of the Anatolian Agricultural Research Institute made it possible to calculate the yield losses due to stripe rust. This calculation was based on yield differences between genotypes at infected and disease-free locations using various methods.Using the method suggested by Campbell et al. (1975) the calculated yield loss due to stripe rust varied among genotypes and locations

Abstract:

Generally, many high-strength alloy materials used in aerospace, power and chemical industries have strength differential effect in tension and compression (SD effects). Usually, in mechanical calculations of sheet metal forming, Treasca yield criterion and Mises yield criterion are applied. Because the yield criterions don’t take SD effects into consideration, the calculation result may have errors for certain materials. However, generalized twin shear stress yield criterion, which takes into account the influence of the intermediate principal stress, is more suitable for most metal materials

Abstract:

The fundamentals of bond pricing revolve around the present value of future cash flows generated by the bond. Calculating Bond Pricing could be tedious as well as complex, especially when differences in terminologies like Face value of the Bond and Current Price of the bond, Coupon rate and Yield are not clear. Understanding bonds and bond pricing is crucial for investors to make informed investment decisions. In this paper, we would study different parameters impacting Bond Price calculation, a simplified formulae to calculate current Price of the Bond with some assumptions and some examples

We report here an R-matrix study of electron collision with the BeO+ molecular ion in its X 2Π ground state and at a single bond length, namely its equilibrium Re=2.7023 a0. Firstly, a good quality configuration interaction calculation is performed for the BeO+ ground and excited states. We then perform scattering calculations using the R-matrix method to yield the cross-section for electronic excitation to several of its excited states. The electron impact dissociation of BeO+ through the two lowest dissociation channels, namely the Be+(2Sg) + O(3Pg) and Be+(2Sg) + O(1Dg) dissociation channel

Abstract:

Glacier snow line altitude (SLA) at the end of the ablation season is an indicator of the equilibrium line altitude (ELA), which is a key parameter for calculating and assessing glacier mass balance. Here, we present an automated algorithm to classify bare ice and snow cover on glaciers using Landsat series images and calculate the minimum annual glacier snow cover ratio (SCR) and maximum SLA for reference glaciers during the 1985–2020 period in Google Earth Engine. The calculated SCR and SLA values are verified using the observed glacier accumulation area ratio (AAR) and ELA. We select 14 ref

Eight clones of sweetpotato [Ipomaea batatas (L.)

There were significant genotypic differences for all NUE components and the variables used for calculation. When total marketable yield was used in calculating NUE, utilization efficiency was always more important than uptake efficiency in accounting for NUE variati

Abstract:

A new digital method for assessing the effect of fertilizers with different NPK ratios on winter wheat yield in field experiments is presented; the validity of the statement is presented: yield and yield increase from fertilizers increase with increasing NPK dose and are proportional to the amount of yield that has not reached the maximum (limit) value, and also proportional to the possible value of yield above some minimum (initial) value of yield, so the change in yield increase is determined by the first-order differential equation in ordinary derivatives. In order to estimate the effect of
