Improved Non-Linear Solution Of Dip Coating Flow, Omar Bin Yusuf
Improved Non-Linear Solution Of Dip Coating Flow, Omar Bin Yusuf
Electronic Thesis and Dissertation Repository
A thin layer of film is developed on the surface of a substrate in the dip coating process where the substrate is initially immersed into the coating fluid and then withdrawn continuously from the coating fluid bath. In this study a two dimensional flow of the thin film for a Newtonian fluid is examined theoretically by dividing the film into three separate regions. A general formulation is developed for a thin film flow, which then simplifies for each region upon considering appropriate assumptions to each region. The influence of inertia and surface tension in the presence of gravity is investigated …
Fuzzy Differential Evolution Algorithm, Dejan Vucetic
Fuzzy Differential Evolution Algorithm, Dejan Vucetic
Electronic Thesis and Dissertation Repository
The Differential Evolution (DE) algorithm is a powerful search technique for solving global optimization problems over continuous space. The search initialization for this algorithm does not adequately capture vague preliminary knowledge from the problem domain. This thesis proposes a novel Fuzzy Differential Evolution (FDE) algorithm, as an alternative approach, where the vague information of the search space can be represented and used to deliver a more efficient search. The proposed FDE algorithm utilizes fuzzy set theory concepts to modify the traditional DE algorithm search initialization and mutation components. FDE, alongside other key DE features, is implemented in a convenient decision …
