In order to improve the performance of a mini-type air-cooled diesel engine in terms overall efficiency and emissions, swirl chamber variable cross-section dual-channel model was developed. This study proposed nine turbulent chambers with for combustion solution, which applied insert between original main chamber. Model-based design, simulation experiments were as feasible approach address this...

High-quality predictions for neutrino-nucleus cross sections are needed for use in ongoing experimental studies of neutrino oscillations at GeV energies, where a fully relativistic treatment of the neutrino-nucleus scattering is mandatory, but hard to achieve. Of course any reliable calculation for neutrino scattering should first be tested against electron scattering in the same kinemati-cal c...

We present a calculation of the next-to-leading order cross section for the inclusive hadroproduction of D and B mesons as a function of the transverse momentum and the rapidity in a massive variable flavor number scheme. We compare our numerical results with recent data from the CDF Collaboration at the Fermilab Tevatron for the production of D0, D⋆+, D+, and Ds mesons at center-of-mass energy...

A new version of the time-dependent close-coupling method is used to calculate the single and double photoionization of the Be and Mg atoms. Total cross sections are calculated using an implicit time propagator with a core orthogonalization method on a variable radial mesh. The double to single photoionization cross section ratios are found to be in good agreement with experiment for both Be an...

The aim of this paper is to study the cross-sectional effects present in the market using a new framework based on graph theory. Within this framework, we represent the evolution of a dynamic portfolio, i.e. a portfolio whose weights vary over time, as a rank-based factorial model where the predictive ability of each cross-sectional factor is described by a variable. Practically, this modeling ...

The present study addresses optimal design of reinforced concrete (RC) columns based on equivalent equations considering deformability regulations of ACI318-14 under axial force and uniaxial bending moment. This study contrary to common approaches working with trial and error approach in design, at first presents an exact solution for intensity of longitudinal reinforcement in column section by...

We study precise calculation of neutralino relic density in the minimal supergravity model. We compare the exact formula for the thermal average of the neutralino annihilation cross section times relative velocity with the expansion formula in terms of the temperature, including all the contributions to neutralino annihilation cross section analytically. We confirm that the expansion formula fa...

In this paper we consider a simultaneous system of spatially interrelated cross sectional equations. Our speci...cation incorporates spatial lags in the endogenous and exogenous variables. In modelling the disturbance process we allow for both spatial correlation as well as correlation across equations. The data set is taken to be a single cross section of observations. The model may be viewed ...

The study of top quark pair production at the Tevatron is now entering the realm of precision physics. With 2.8 fb−1 of CDF data there are over 1200 reconstructed tt̄ events in the lepton + jets channel. As the integrated luminosity increases, it is possible to improve not only measurements of the properties of the top quark but also maybe to search for new physics by comparing the tt̄ cross sect...
