Solving the direct kinematics of parallel spherical mechanisms with l legs boils down to solving systems of l 1 second-order multinomials. This paper presents a recurrent expression for the control points of these multinomials when expressed in Bernstein form. This result allows us to propose a technique for solving the direct kinematics of these mechanisms that takes advantage of the subdivisi...

It has been shown that (i) dynamic constrained optimisation problems (DCOPs), a very common class of problems in real-world applications, have some special characteristics that make them very different from unconstrained dynamic problems and stationary constrained problems and (ii) some existing dynamic optimisation (DO) and constraint handling (CH) algorithms might not work effectively in solv...

This paper introduces a human-agent interaction framework that allows human and computational mechanisms to interact in a seamless manner to collaboratively perform problem solving tasks in the Semantic Web. The framework is based on a combination of services supported by intermediate domain ontologies and flexible mapping mechanisms that map agent and human internal representations and externa...

Greater skill in solving single-digit multiplication problems requires a progressive shift from a reliance on numerical to verbal mechanisms over development. Children with mathematical learning disability (MD), however, are thought to suffer from a specific impairment in numerical mechanisms. Here we tested the hypothesis that this impairment might prevent MD children from transitioning toward...

Differential equations, both fractional and ordinary, give key tools in understanding the mechanisms of physical systems solving various problems nonlinear phenomena [...]

Research in distributed problem solving in the last years focused on distributed applications which cooperate to accomplish a task. Another level of distributed problem solving is that of human teams which are distributed in space and cooperate in solving a problem. In this paper we will introduce distributed problem solving from the `human level', brie y present the accompanying research area ...
