The effect of the nucleon recoil for antikaon-deuteron scattering is investigated in the framework of effective field theory. In particular, we concentrate on the calculation of the nucleon recoil effect for the double-scattering process. It is shown that the leading correction to the static term that emerges at order ξ with ξ = MK/mN vanishes due to a complete cancellation of individually larg...

The publication updates the issue of wagon repair in modern conditions and highlights main problems associated with method organization work. Low productivity is due to outdated equipment worn-out rolling stock, poor training staff involved. article contains provisions changing repair, calculating possibility loading production positions, program repairing wagons, determining number ways their ...

In a sampled data system, frequency components greater than half the sampling rate "alias" (shift) into the frequency band of interest. Most of the time, aliasing in an undesirable side effect, so the "undersampled" higher frequencies are simply filtered out before the A/D stage. But sometimes, the undersampling is deliberate and the aliasing causes the A/D system to function as a mixer. This a...

car body acceleration is an important factor affecting track safety and ride comfort, which are two primary aspects of railway systems. though track level is an important source of wagon body acceleration, no quantitative relation between them is available and the aim of this paper is to propose a method to address this issue. to do so, car body acceleration is determined using a 10 dof simulat...

energy consumption is very high in greenhouses mainly due to off-season production. the main source of its energy supply is fossil fuels. due to the disadvantages of fossil fuels consumption and preventive laws in the incoming years, study on reducing consumption and replacing a part of them with renewable energy is essential. in this research, a solar heating system, equipped with a concentrat...

Urban transport problems in Pakistan are managed by building larger and better roads. By contrast, the principles of sustainable transport encourage using lowcost public transport that could perform well in mixed land use and high density Pakistani cities. The purpose of this paper is to provide a critical overview of public transport policy in Pakistan from the British India period through to ...
