Kinect Based Physical Player Interactive Game Using Mealy Model in Unity K-Infinite Runner
Abstract: AbstractRecently, game structures are designed using NFA (Non-Deterministic Finite Automata) and DFA (Deterministic Finite Automata). NFA can reside at the same time in multiple states and hence it must be converting into DFA and then we used DFA to implement the game design. Conversion takes extra efforts and sometimes leads to ambiguous states. In our proposed modeled game, we used a Mealy machine to implement a game design which describes …

Predicting the Physical Property of Asphaltene Molecule using Fuzzy System
Abstract: Asphaltenes — the heaviest and most aromatic compounds of crude oil— have a strong tendency to aggregate in solution to form complex colloidal structures. They generally impede producing, transporting and refining of crude oil resources. An indepth knowledge of the physical behavior of asphaltenes is needed to mitigate these effects. Predicting the physical behavior of asphaltene such as density is complex and nonlinear as it is a complex molecular mixture …
