Cables have always been under consideration as a structural element because of important features such as large strength to weight ratios and long spans. Their equilibrium analysis is an important issue in this regard. But this analysis involves highly nonlinear equations arising from large deformations and material nonlinearity. Different methods have been under use for numerical analysis of s...

Abstract: Parenteral Nutrition Formulae in Iranian Generic Project were studied in 31 patients hospitalized in ten major general hospitals in Tehran and Shiraz. Estimated theoretical energy (Calculated Energy Value or CEE) using Harris- Benedict equations and applying the Cerra stress factor was compared with the amount of energy estimated via indirect calorimetric technique (Measured Energy ...

It is shown that consistent with Heisenberg's statistical theory of turbulence, equations of motion for a turbulent flow can be derived. These equations are linear integro-differential equations expressing the non-local interaction of eddies with different wave numbers on the basis of Heisenberg's statistical theory. The nonlocal terms in these equations of motion for turbulent flow have to be ...

Although, the Stirling engine (SE) was invented many years ago, the investigation on SE is still interesting due to variety of energy resources can be applied to power it (solar energy, fossil fuel, biomass and geothermal energy). In this paper, the thermodynamic cycle of SE is analyzed by employing a new analytical model and a new method is presented to evaluate output power and efficiency of ...

the study examined gender analysis of energy use for rice production in north central nigeria using a sample of 60 rice farmers. an analysis of gender relations provides the information on the different conditions men and women face, and the different effects that policies and programs may have on them. simple descriptive statistics were used to analyze the data. energy efficiency and energy pr...

This paper addresses the validity of radiative transfer equations as a model for the energy density of waves propagating in highly heterogeneous media. Comparisons between acoustic wave simulations over domains of size comparable to 500 wavelength in two space dimensions and Monte Carlo simulations of radiative transfer equations are performed. In the so-called weak coupling regime, the agreeme...

In this article, finite difference method (FDM) is used to solve sixth-order derivatives of differential equations in buckling analysis of nanoplates due to coupled surface energy and non-local elasticity theories. The uniform temperature change is used to study thermal effect. The small scale and surface energy effects are added into the governing equations using Eringen’s non-local elasticity...

The fundamental solution of the system of differential equations in bio-thermoelasticity with dual phase lag (DPL) in case of steady oscillations in terms of elementary function is constructed and basic property is established. The tissue is considered as an isotropic medium and the propagation of plane harmonic waves is studied. The Christoffel equations are obtained and modified with the ther...

The way Energy, Economy and Environment systems correlate along with the appropriate policy will bring about a countries sustainable growth and economic development (E3 Models). The models deals with the relation between these aspects are generalized versions of economic growth models which take into account the energy and environmental factors. This research analyses concurrent efffect of ene...
