A novel image and infrared data-based application to assist visually impaired (VI) users in detecting and avoiding obstacles in their path while independently navigating indoors is proposed. The application will be developed for the recently introduced Google Project Tango Tablet Development Kit equipped with a powerful graphics processor and several sensors which allow it to track its motion a...

• A CFD model to predict aeration of spillway flow. Highly economical approach combining VOF with explicit modelling air entrainment. Tested at four different step Froude numbers and validated by experimental data. Model implemented within the framework OpenFOAM. This work considers application entrainment developed in [P. Lopes et al. Int. J. Nonlin. Sci. Num., vol. 18, pp. 559-574, 2017] simu...

This paper describes a virtual historically simulated environment with inbuilt evaluation mechanisms to test the effect of various levels of interactivity on user engagement and immersion in a foreign cultural environment. The proposed evaluation mechanisms are computer scripted agents, dynamic physical environments, culturally situated tasks and artifacts, and multi-layered ‘memento maps’. As ...

Abstract The current paper deals with the performance evaluation of application three soft computing algorithms such as adaptive neuro-fuzzy inference system (ANFIS), backpropagation neural network (BPNN), and deep (DNN) in predicting oxygen aeration efficiency (OAE20) gabion spillways. Besides, classical equations, namely multivariate linear nonlinear regressions (MVLR MVNLR), including previo...
