Computer animation has been a popular research topic since 1970s, when the first parametric facial model is proposed[0]. In the recent few years, a lot of techniques are proposed to model and animate faces like physical modelling, motion capture, mesh deformation etc. However, most of them require burden work of artists and assistance of expensive model. Rigging is one kind of the most popular ...

In the 1960s the isolated tropical forest enclave of Quintana Roo was targeted by the Mexican Government to serve as the cornerstone for launching what is now considered to be one of Mexico’s most successful economic development strategies – Planned Tourism Development (PTD). This paper commences with a brief review of the role of state-driven PTD in Mexico’s national economic development agend...

Across two years, we examined the effects of teachers’ attempts to implement computer supported collaborative learning (CSCL) communities in classrooms in two high schools on students’ knowledge building, strategic learning, and perceptions of the classroom environment. In year one, 429 (fall) and 317 (spring) students in the classes of 8 teachers and in year two, 946 students in the classes of...

This paper examines the presence and distribution of plastic particles in waters off the NW Spanish Atlantic coast. A pilot sampling program was initiated in 2013 to study the presence of plastic particles in surface waters. A total of 41 neuston samples were collected using a manta trawl fitted with a 333 μm mesh (21 samples in 2013 and 20 samples in 2014). Several types of plastic particles w...

Natural dynamics can be exploited in the control of bipedal walking robots: the swing leg can swing freely once started; a kneecap can be used to prevent the leg from inverting; and a compliant ankle can be used to naturally transfer the center of pressure along the foot and help in toe off. Each of these mechanisms helps make control easier to achieve and results in motion that is smooth and n...

Structural tests using dynamic substructuring methods require a robust controller to synchronise the numerical and physical responses, and a stable and accurate algorithm to simulate the numerical components. The proposed new substructuring strategies use real-time finite element methods to guarantee modelling accuracy and output-based controllers to achieve robust synchronisation. Output-based...
