The wheel-legged hybrid structure has been utilized by ground mobile platforms in recent years to achieve good mobility on both flat surface and rough terrain. However, many designs of the obstacle-crossing part transformation driving this is highly coupled, which limits its optimal performance aspects. This paper presents a novel robot with rim shape changeable wheels, bi-directional smooth ab...

Several studies have considered the auditory identification of foreign-accented/nonnative speech. Here, a finer-grained alternative to the traditional definition of speech based on the usual criterion of birthplace alone, yet accommodates complexities which arise when dealing with speakers from countries which are historically diverse, ethnically. Using the foregoing construct, this study exami...

This study presents a framework for coordinating multi-area optimal power flow with adjustable network topology in an electric power system. The modelling is accomplished in a coordinated but not a centralised fashion. Each regional operator dispatches its own generation and switches its own transmission network to reach its optimal benefits. The proposed model uses augmented Lagrangian relaxat...

In a (r, n)-threshold secret sharing scheme, no group of (r − 1) colluding members can recover the secret value s. However, the number of colluders is likely to increase over time. In order to deal with this issue, one may also require to have the ability to increase the threshold value from r to r′(> r), such an increment is likely to happen several times. In this paper, we study the problem o...

The variation of photonic orbital angular momentum at Compton scattering is 7 characterized. We determine scattering matrix of a twisted light based on the fundamental 8 conservation of orbital angular momenta. Numerical values for two different twisted light modes: 9 Laguerre Gaussian and Bessel Gaussian, are generated and illustrated. Our analysis indicate that 10 states of photonic orbital a...

Agent technology is often suggested as a tool for developing software that is more adaptive in the face of changes in its environment. In agent-based approaches, complex automated systems are built from components that communicate with each other. To enable adaptive behaviour, both the components themselves and the communication architecture should be easily changeable. This paper presents the ...

Predicting real-time movement trace of remote objects or the control points of objects when delay-jitter occurs is a critical and challenging issue in most Internet-based collaborative graphics editing systems. This paper presents two novel algorithms: Machine Learning algorithm and Changeable Scale algorithm. Related experiments were carried out to test the effectiveness of the algorithms. Res...

introduction: with the increasing role of the internet as one of the most important sources of information on the one hand, and the enhancement of its usability on the other, it is necessary for web designers and developers to be familiar with the criteria that make a website usable. therefore, this paper aimed to provide knowledge about the interactivity, changeability , and non-textual conten...
