Abstract We apply the concept of servo constraints to end-effector trajectory tracking control parallel robots with structural link flexibilities. Such deliver inverse robot model where solution approaches via projections are proposed, which transform resulting differential-algebraic equations ordinary differential equations. The applicable process depends on existence and stability internal dy...

Many CSPs can be effectively represented and efficiently solved using matrix models, in which the matrices may have symmetry between their rows and/or columns. Eliminating all such symmetry can be very costly as there are in general exponentially many symmetries. Cost-effective methods have been proposed to break much of the symmetry, if not all. In this paper, we continue with this line of res...

We review research on the ̄uency heuristic as a basis for the subjective experience of familiarity. Then, we explore the links between the construct of ̄uency and the automatic versus consciously controlled memory processes that are estimated using the process dissociation procedure, and the phenomenological experiences studied using ``Remember'' and ``Know'' judgements. Although the ̄uency tha...

In this paper, finding Dynamic Load Carrying Capacity (DLCC) of flexible link manipulators in point to-point motion was formulated as an optimal control problem. The finite element method was employed for modelling and deriving the dynamic equations of the system. The study employed indirect solution of optimal control for system motion planning. Due to offline nature of the method, many diffic...

One of the objectives for conducting research in the field of design is to increase the knowledge about the design processes and that could to lead to more satisfactory products. In this paper we will look at some examples that seem to have had influence from research. Some of these examples show success and others were not so successful. This is a very complex and large field and the ambition ...

A low-level flexible-structure control is proposed for designing control systems capable of efficiently handling constraints on the manipulated variables of heat exchanger networks (HENs). Flexible-structure refers to the capability of the resulting control system to switch from one closed-loop structure to another in order to keep regulation, and low-level means that it can be configured in mo...

Rational choice when preferences are not required to be transitive and complete has been discussed in the literature for years. In this article transitivity and completeness of the preference relation is also not assumed. It will be shown that nevertheless the existence of a competitive equilibrium can be proven when those properties are replaced by a domination property which allows that there...

We present a comprehensive study of the use of value precedence constraints to break value symmetry. We first give a simple encoding of value precedence into ternary constraints that is both efficient and effective at breaking symmetry. We then extend value precedence to deal with a number of generalizations like wreath value and partial interchangeability. We also show that value precedence is...

Human learning, although highly flexible and efficient, is constrained in ways that facilitate or impede the acquisition of certain systems of information. Some such constraints, active during infancy and childhood, have been proposed to account for the apparent ease with which typically developing children acquire language. In a series of experiments, we investigated the role of developmental ...
