O presente trabalho mostra um estudo sobre a presença de pares de íons de CN- - Cu+ e OCN- -Cu+, em cristais de KCl, usando técnicas de medidas de corrente de despolarização termoestimulada (I.T.C.) e Absorção óptica. A detecção destes pares foi feita através de um estudo sistemática de correlação entre as diferentes amostras aqui usadas: KCl + 1% KCN; KCl + 1% CuCl; KCl + 1% KOCN; KCl + 1% KOCN + 1% CuCl e KCl + 1% KCN + 1% CuCl. Deve ser ressaltado que a última amostra apresenta um tipo de impureza não intencional OCN- , cuja associação com o íon Cu+ também é observada. Na absorção ótica observamos bandas à temperatura ambiente em 210, 228, 242, 252, 260 e 290 nm para o cristal de KCl + 1% CuCl + 1% KCN, sendo que para o cristal de KCl + 1% KOCN + 1% CuCl não foi observado o último pico. As diferentes bandas são atribuídas às possíveis interações entre Cu+ e CN-, bem como Cu+ e OCN-. Quanto à técnica de ITC, as curvas obtidas por esta, para os três últimos cirstais citados acima, foram melhor ajustadas pela somatória de duas curvas singulares de ITC, cujas temperaturas de pico estão nas posições de 53 e 55 K; 54,3 e 56,6 K; 53,3 e 56,1 K, respectivamente. Em KCl + 1% KOCN a curva de mais baixa temperatura (curva 1) de ITC é atribuída à molécula (16O12C14N-) e a curva de mais alta temperatura (curva 2) é atribuída à molécula isotrópica (18O12C14N-). Para as amostras de KCl + 1% KOCN + 1% CuCl a curva 1 foi atribuída ao OCN- isolado e a curva 2 ao Cu+ perturbado pela presença do OCN-. Quanto ao cristal de KCl + 1% KCN + 1% CuCl, as duas técnicas propostas não foram suficientes para identificar a presença de pares Cu+ - CN-, necessitando, desta maneira, da utilização de outra técnica experimental, como por exemplo a da luminescência. A correlação dos resultados experimentais foi feita através dos parâmetros determinados do momento de dipolo (p), energia de ativação (Ea&#8727) e a temperatura de pico (Tm&#8727) / The present work gives a study on CN- - Cu+ and OCN- -Cu+ coupled pairs doped KCl single crystal, by using Ionic Thermal Current (I.T.C.) and Optical absorption techniques. These pairs were detected through a systematic correlation study between different samples: KCl + 1% KCN; KCl + 1% CuCl; KCl + 1% KOCN; KCl + 1% KOCN + 1% CuCl and KCl + 1% KCN + 1% CuCl, were the last sample shows unporposely doping OCN-, compled with Cu+. The observed optical absorption bands, at room temperature, were in 210, 228, 242, 252, 260 and 290 nm for KCl + 1% CuCl + 1% KCN crystal. Only the last absorption band was not seen in KCl + 1% KOCN + 1% CuCl samples. Diferent bands are associated with possible interactions between Cu+ and CN-, as also Cu+ with OCN-. The ITC curves for the last three crystals were better fitted with two single ITC´s curves, whose temperature peaks are at 53 and 55 K; 54,3 and 56,6 K; 53,3 and 56,1 K, respectively. The lowest temperature ITC band (curve 1) in KCl + 1% KOCN is attributed to the (16O12C14N-) molecule and the highest temperature ITC band (curve 2) is due to the (18O12C14N-) isotropic molecule. For KCl + 1% KOCN + 1% CuCl samples curve 1 was associated with isolated OCN- and curve 2 with Cu+ perturbed with OCN-. With KCl + 1% KCN + 1% CuCl, the two techniques were not good enough to identify Cu+ - CN-, compling, it should be necessary to apply another type of techniques, like luminescence. The correlations of the experimental results were done through the determination electric dipole moment (p), activation energy (Ea&#8727) and temperature peak (Tm&#8727) parameters

<p>The purpose of this report is to implement and evaluate parts of the simulation software used in the SoCBUS project. In order to complete and evaluate the entire software package, a traffic model and a stimuli generator must be implemented. They are implemented and evaluated together with the entire simulator software. The purpose of the Traffic model is to model communication traffic as good and descriptive as possible. The output of the Traffic model is called a test case, which works as input for the Stimuli generator. The Stimuli generator computes and creates an event list for the Simulator. This report will investigate and motivate the presented traffic model and stimuli generator in detail. The simulator software is then tested with two separate test cases in order to investigate if the simulator software works properly. The results are promising and the simulator software behaves as expected.</p>
