Sac metal kalıplarının optimizasyonu ve uygulaması

Yüksek Lisans TeziTezde sac metal kesme ve sıvama kalıplarının dizaynı, üretim aşaması, montajı (toplanması), makineye bağlanması, üretimi, diğer yöntemlere göre farkları incelenecektir. Bununla beraber kesme kalıplarının optimizayonu baş etken olacaktır. Kısaca bir kalıp yapılırken en az fire vererek ve birkaç farklı numuneyi aynı kalıpta toplama aşamalarını inceleyeceğiz ve bununla birlikte gerekli olan hesaplamaları yapacağız.AbstractIn this thesis, design of sheet metal cutting and forming dies, processing steps, concerned with quality of the machines, mold production, differences compared to other methods. Using different materials for the mold should be obtained collectively establish the structure of system properties examined. Both system design implementation flow of material examined the mold, the mold system will be established. Sheet metal cutting and forming patterns thesis design, manufacturing process, assembly (collection), concerned with the machine, the production and the differences compared to other studied methods. The results of mold making should be obtained after the application of scientific and material alternatives then will focus on the new model of data as a result. These alternatives are evaluated according to the methods of production of new materials’ propertie

Entropy Production in Non-Markovian Collision Models: Information Backflow vs. System-Environment Correlations

We investigate the irreversible entropy production of a qubit in contact with an environment modelled by a microscopic collision model in both Markovian and non-Markovian regimes. Our main goal is to contribute to the discussions on the relationship between non-Markovian dynamics and negative entropy production rates. We employ two different types of collision models that do or do not keep the correlations established between the system and the incoming environmental particle, while both of them pertain to their non-Markovian nature through information backflow from the environment to the system. We observe that as the former model, where the correlations between the system and environment are preserved, gives rise to negative entropy production rates in the transient dynamics, the latter one always maintains positive rates, even though the convergence to the steady-state value is slower as compared to the corresponding Markovian dynamics. Our results suggest that the mechanism underpinning the negative entropy production rates is not solely non-Markovianity through information backflow, but rather the contribution to it through established system-environment correlations
