In international pistol shooting competition the performance improvement needed to be able to move into a medal winning position in a final from fourth position is 1.5 points (Bedford et al., 2012). It may be expected therefore, that by providing a method of reducing tremor resulting in a corresponding performance improvement. This research consists of two studies investigating the physiological response and the shooting performance of elite pistol shooters.

The thesis is performed theoretically and experimentally. The theoretical studies on the dynamics of the single short pulse emission using transient cavity method and narrow linewidth and tunable wavelength generation using Littrow grating configuration were performed. On the other hand, the experimental investigations were carried out Experimental research was carried out based on the optimal results obtained by the theoretical studies.

The research in this thesis follows two directions: The first, using high performance computing currently available, we studied atomic and molecular emissions in astrophysical environment. The radiative transfer model was applied to explain the characteristics of the recombination line masers Hnα in the envelope of the star MWC 349A.

In Vietnam, currently the study of fuel cells is almost neglected and there is very little fundamental research on this issue. The research on fuel cells of our country is at innitial stage, mainly researching catalytic material in the laboratory and almost has not research in the technology of manufacturing fuel cell (stack).
