Turbojet engines have a slow response and require mechanical assistance to perform vertical take-offs landings. In this paper, we propose take-off landing (VTOL) aircraft that contains one-dimensional thrust vectoring nozzle modules solve the problem of dependence on turbojet. The turbojet engine is placed horizontally in module, rotational speeds are fixed, force along axis remains constant as...

We discuss restrictions of two-dimensional translation-invariant Gibbs measures to a one-dimensional layer. We prove that there exists a translation invariant a.s. absolutely convergent potential making these restrictions into weakly Gibbsian measures. We discuss the existence of the thermodynamic functions for this potential and the variational principle for the weakly Gibbsian measures.

A new NMR experiment for correlating diffusion coefficients and chemical shifts is presented. This experiment provides the same information as the conventional DOSY experiment, but only requires a single dimension because a nonuniform magnetic field gradient is used to encode the diffusion information into the lineshapes of the peaks in the chemical shift dimension. By fitting the resulting lin...

For a long time, lower bounds on the difficulty of estimation have been constructed by showing that estimation was difficult even in certain 1-dimensional subproblems. The logical extension of this is to identify hardest one dimensional subproblems and to ask whether these are, either exactly or approximately, as difficult as the full problem. We do this in three settings: estimating linear fun...

Based on reasonable assumptions and mathematical approximations a one dimensional, analytical model for solar quiescent prominences is constructed, which is in both magnetohydrostatic and thermal equilibrium. Thermal equilibrium here is a balance among thermal conduction, radiation and wave heating. The wave heating (H) is assumed to be equal to a constant (EH ) times the product of pressure (p...
