Opis:: In this paper, the temperature distribution in fiber lasers pumped by multi diode bars located in out-of-fiber axis has been investigated semi-analytically. For this reason, we consider heat deposition in fiber lasers due to pump and the nonhomogeneous heat conduction equation has been solved by using Green function method in a cylindrical coordinate system. Our model has been used for single, double and multi pumped configuration and, for a typical fiber lasers, the results have been plotted and discussed.

Opis:: An improved simple method is presented for calculation of the detonation velocity of CHNO and CHNOFCl explosives, as well as non-ideal explosives containing aluminum (Al) and ammonium nitrate (AN) additives. In contrast to the available complex computer codes, where the estimated detonation velocities of non-ideal explosives for equilibrium and steady state calculations show significant differences from the measured data, this simple method gives more reliable results. Suitable decomposition paths are suggested in which the partial interaction of Al with the gaseous products and the decomposition of AN are assumed for composite explosives containing Al/AN additives. The predicted detonation velocities using the new method are good compared to those from one of the well-known empirical methods and from computer codes using full and partial equilibrium of Al/AN.

Opis:: A novel method is introduced for the reliable prediction of the condensed phase (solid or liquid) heat of formation (Δf H θ (c)) of triazolium-based energetic ionic salts (EISs) at 298.15 K. It is based on the influence of some specific elemental compositions of cations and anions as additive parts. Two correcting functions, as non-additive quantities, are also used to adjust the first part. The coefficients of the specific elemental compositions of cations and anions in the new correlation, with a negative sign as well as a negative correcting function in the triazolium-based EISs, can decrease the value of Δf H θ (c) for the corresponding EISs. The reported Δf H θ (c) values of 57 different triazolium-based EISs were used to derive the new model. For 34 triazolium-based EISs, where the outputs of quantum mechanical methods were available, the Root Mean Squared Error (RMSE) of the new model was 156.0 kJ/mol. Meanwhile, the RMSE of complicated quantum mechanical methods is very large, i.e. 298.0 kJ/mol. The high reliability of the new model was also confirmed for a further 5 complex triazolium-based EISs as compared to the results of quantum mechanical calculations.
