Article Gezegensel Siyaset Manifestosunun ardından yeşil teorinin uluslararası ilişkilerdeki konumu(Uluslararası İlişkiler Konseyi Derneği, 2022) Buhari Gülmez, Didem; Aydın Dikmen, BengüThis article sheds light on the current debates on the Planetary Politics Manifesto in order to better locate Green Theory in International Relations. In particular, it aims to go beyond the problem-solving vs critical theories binary that is observed in the studies on the location of Green Theory in the discipline. Therefore, rather than comparing Green Theory with the mainstream theories of International Relations, it focuses on the complex relationship between Green Theory and major critical theories such as Constructivism, Normative Theory, Poststructuralism, Critical Theory, Postcolonialism and Feminism from the perspective of the Planetary Politics Manifesto.Article Citation - WoS: 3Citation - Scopus: 2Prediction of Microdrill Breakage Using Rough Sets(Cambridge University Press, 2011) Sevil, Hakkı Erhan; Özdemir, SerhanThis study attempts to correlate the nonlinear invariants’ with the changing conditions of a drilling process through a series of condition monitoring experiments on small diameter (1 mm) drill bits. Run-to-failure tests are performed on these drill bits, and vibration data are consecutively gathered at equal time intervals. Nonlinear invariants, such as the Kolmogorov entropy and correlation dimension, and statistical parameters are calculated based on the corresponding conditions of the drill bits. By intervariations of these values between two successive measurements, a drop–rise table is created. Any variation that is within a certain threshold (+-20% of the measurements in this case) is assumed to be constant. Any fluctuation above or below is assumed to be either a rise or a drop. The reduct and conflict tables then help eliminate incongruous and redundant data by the use of rough sets (RSs). Inconsistent data, which by definition is the boundary re-gion, are classified through certainty and coverage factors. By handling inconsistencies and redundancies, 11 rules are ex-tracted from 39 experiments, representing the underlying rules. Then 22 new experiments are used to check the validity of the rule space. The RS decision frame performs best at predicting no failure cases. It is believed that RSs are superior in dealing with real-life data over fuzzy set logic in that actual measured data are never as consistent as here and may dominate the monitoring of the manufacturing processes as it becomes more widespread.
