Investigation of the Ni3Al-Fe alloys by resistivity measurements and differential thermal analysis
A series of iron-doped Ni3Al ternary alloys is investigated by resistivity measurements and differential thermal analysis. Temperatures of phase transformations and disordering onset are determined. A hysteresis phenomenon is observed in the liquid state in polytherms of resistivity upon heating the alloy under study to the critical temperature. © 2013 Allerton Press, Inc
Reducing digger energy consumption by improving the walking mechanism
To evaluate the energy to move the excavator body, we calculated the effort involved in the hydraulic cylinders of the walking mechanism. Unlike man, "pacing" the excavator is on a "drawing", in which the housing pulls the excavator walking mechanism in the direction of the reference points. As a result, the kinematic and dynamic study of the process of pacing is reduced to the analysis of speeds and loads for the simplest of mechanisms, known since ancient times as the slider-crank mechanism. Analysis of the motion of this mechanism can be carried out by conventional (calculated for one position) or by modern analytical methods. Modern methods of analytical studies of the mechanisms permit a computer calculation of the full cycle of movement of the excavator in a single step and to evaluate the stresses produced in the hydraulic cylinders. A variety of design solutions based on different positions of the connecting joints is recorded during the test set kinematics and, accordingly, an amount in the results is obtained. Power movement by one step excavator is theoretically estimated as the amount of work the forces acting on the mechanism during this step undertake. A design that corresponds to the minimum energy consumption should be considered optimal for this type of walking mechanism. The authors of this paper analyzed the performing over thirty different types of mechanisms of pacing. Recommendations for optimizing their designs are formulated for each of these, which not only reduces the power consumption excavator, but also reduces its price. © 2014 WIT Press
Impacts of Risk Perceptions on Foreign Direct Investment in Energy Generation and Transmission Projects in Russia
This paper deals with an issue relevant for Russia’s energy policy, namely, the need to attract private investment, including foreign direct investment, in renovation and upgrading of energy infrastructure. Based on the survey that involved private investors from several countries, the paper addresses the question of how investors perceive private investment risks existing in Russia. Further, the conclusions are made about how these perceptions might affect private investment in energy systems projects in Russia. The results demonstrate that improvements in policy and institutional frameworks are needed in order to attract private investment, especially, in such projects with medium and long-term planning horizon and return of investment as deployment and upgrading of energy generation and transmission infrastructure in Russia
