    Asaf Hâlet Çelebi şiirlerinde ara konumda fantastik
    (2010) Akdeniz, Sıla
    Asaf Hâlet Çelebi, not being involved in any poetic movement, was considered to be “odd” or “extraordinary” in his time, and is still widely seen as such today. Due to the difference and peculiarity of his poetry, he was widely criticized and little appreciated. Studies of Asaf Hâlet Çelebi have mostly concentrated on the mystic elements used in his poetry. Elements that have been particularly focused upon have been the elements he acquired from Eastern culture and Islamic mysticism, the expressions from older civilizations that are commonly seen in his poetry, his direct use of phrases in diverse languages, and his allusions and references to a multiplicity of different texts. More recent studies of Asaf Hâlet Çelebi have pointed out his frequent use of fable, yet have done no more than point out his use of fable motifs and move on; no extensive research on the subject has been done thus far. In this study, however, it is the relationship between Asaf Hâlet Çelebi’s poetry and the fantastic that will be examined. “Abstraction”, the guiding principle of Çelebi’s poetry, will be examined in terms of its effect on “liminality”. Ultimately, it is the fantastic which emerges from or is approached in Çelebi’s poetry that is examined.

    A critical review of the approaches to optimization problems under uncertainty
    (2001) Gürtuna, Filiz
    In this study, the issue of uncertainty in optimization problems is studied. First of all, the meaning and sources of uncertainty are explained and then possible ways of its representation are analyzed. About the modelling process, different approaches as sensitivity analysis, parametric programming, robust optimization, stochastic programming, fuzzy programming, multiobjective programming and imprecise optimization are presented with advantages and disadvantages from different perspectives. Some extensions of the concepts of imprecise optimization are also presented.
