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...

The hopping machine considered in this paper is like a pogo-stick; it has a small foot and a leg spring. Unlike a pogo-stick which uses a mechanical spring, the spring for the hopper is pneumatic. The controller is based on Raibert’s three-part control system [1]. Raibert controlled hopping height by delivering a specified thrust value during stance. This paper describes a model-based height co...

in this paper, the dynamic simulation for a high pressure regulator is performed to obtain the regulator behavior. to analyze the regulator performance, the equation of motion for inner parts, the continuity equation for diverse chambers and the equation for mass flow rate were derived. because of nonlinearity and coupling, these equations are solved using numerical methods and the results are ...

in this paper the design of a biped robot actuated with shape memory alloy (sma) springs with minimum degrees of freedom is presented. sma springs are a class of smart materials that are known for their high power to mass and volume ratios. it was shown that utilizing spring type of smas have many advantages as large deformation, smooth motion, silent and clean movement compared to ordinary typ...

A fiber-optic accelerometer based on extrinsic Fabry-Perot interferometer (EFPI) is reported. The sensor adopts flywheel diaphragm structure as a sensitive element, where the mass block bonded in center, while beam of acts spring. element forms single degree freedom spring-mass-damper system. parameters are designed finite simulation (FEM), and transfer function established by numerical simulat...

In this paper, the architecture, processing errors analysis and optimization method of a dual-mass silicon micro-gyroscope are presented. The dual-mass silicon micro-gyroscope consists of two identical single mass gyroscopes and a lever mechanism. Driving decoupling springs and sensing decoupling springs are key components to achieve motion decoupling. The processing error analysis indicates th...

Results, and Innovations in Nutrition Globally (SPRING) project that use secondary analysis of Demographic and Health Survey data to determine barriers to distribution and consumption of iron–folic acid (IFA) through antenatal care systems in a range of countries. This brief describes key characteristics of and barriers to successful IFA supplementation in Senegal. SPRING NUTRITION TECHNICAL BRIEF
