Simulation Scheme

The accuracy of multislice high-resolution transmission electron microscopy (HRTEM) simulation can be improved by calculating the scattering potential using density functional theory (DFT) Gemming, T.; Möbus, G.; Exner, M.; Ernst, F.; Rühle, M. J. Microsc. 1998, 190, 89–98. doi:10.1046/j.1365-2818.1998.3110863.xDeng, B.; Marks, L. D. Acta Crystallogr., Sect. A 2006, 62, 208–216. doi:10.1107/S010876730601004X. This approach accounts for the fact that electrons in the specimen are redistributed according to their local chemical environment. This influences the scattering process and alters the absolute and relative contrast in the final image. For light element materials with well defined geometry, such as graphene and hexagonal boron nitride monolayers, the DFT based simulation scheme turned out to be necessary to prevent misinterpretation of weak signals, such as the identification of nitrogen substitutions in a graphene network. Furthermore, this implies that the HRTEM image does not only contain structural information (atom positions and atomic numbers). Instead, information on the electron charge distribution can be gained in addition. In order to produce meaningful results, the new input parameters need to be chosen carefully. Here we present details of the simulation process and discuss the influence of the main parameters on the final result. Furthermore we apply the simulation scheme to three model systems: A single atom boron and a single atom oxygen substitution in graphene and an oxygen adatom on graphene.

For the problems of few current defogging effect evaluation methods and limited evaluation methods, it proposes an image clarity effect evaluation method: the method combined with relative contrast and edge similarity. This is because: the contrast degree of fog image and non-fog image is obviously different. While improving image contrast degree, it should also try to make the edge structure of recovery image and reduced image consistent to prevent the recovery image from distorting. The experiment proves that this method can effectively evaluate the clarity effect of each algorithm, and the evaluation result and the subjective feelings of the human eyes are consistent. Compared with the existing evaluation methods, it obtains overall evaluation conclusion and also has a good practicability and reliability.

Political Party Affiliation

Chapter 4 investigates Armenians’ stance in the 1957 elections and in the ‘general’ Lebanese and the intra-Armenian mini-civil war of 1958. Armenian parties participated in, and contributed to, political tensions in Lebanon. Simultaneously, they used their position in the Lebanese political system to jostle for power within their own community – a development that turned violent and ended only in December 1958, almost two months after the Lebanese mini-civil war had ended. This tension and violent confrontation between Armenian parties and their armed men had a crucial spatial effect: it unprecedentedly territorialized certain neighborhoods of Beirut. Whereas parts of Lebanon were organized by sects and classes, by relative contrast, it was according to political party affiliation that in 1957/1958 many Armenians of Mar Mikael, Sin el Fil, Bourj Hamoud, and Corniche el-Nahr were re-sorted and relocated, often by force. Lebanese Armenians aligned along the right-left fault lines that divided Lebanese politics and society— more than other confessions, indeed. Vice versa, the Lebanese state was Armenianized, as it were, in that it started to pay more attention to Armenian matters than before, intervening directly and by military force in Armenian neighborhoods in order to finally end the internecine Armenian confrontation.
