User manipulation of assembly models can provide insight during the early, formulative design stages into kinematic and dynamic characteristics of a mechanism. We present the advantages of kinematic representation of constraint equations in fully Cartesian coordinates, a departure from standard practice for interactive mechanical assembly at interactive rates. Formulations of a surface rolling ...

When natural language processing tasks overlap in their linguistic input space, they can be technically merged. Applying machine learning algorithms to the new joint task and comparing the results of joint learning with disjoint learning of the original tasks may bring to light the linguistic relatedness of the two tasks. We present a joint learning experiment with dependency parsing and semant...

This paper presents a set of tools based on explanations for constraint programming. These tools exploit k-relevant explanations which enable us to use several explanations, which can sometimes leads to better diagnosis. k-relevant explanations are introduced and used to provide: diagnosis tools (state analysis, contradiction analysis, constraint impact analysis), interaction tools (dynamic con...

Satisfactory performance of the transverse joints is crucial for achieving the intended service life of jointed plain concrete pavement. An accurate prediction of joint opening and movement is desired in order to quantify the effects of the environment, base type, concrete material constituents, and slab geometry on the concrete pavement responses. In this paper, an analytical model based on el...

Constraint Programming is a powerful programming paradigm with a great impact on a number of important areas such as logic programming [45], concurrent programming [42], artificial intelligence [12], and combinatorial optimization [46]. We believe that constraint programming is also a rich source of many challenging algorithmic problems, and cooperations between the constraint programming and t...

We examined the visual perception of joint actions, in which two individuals coordinate their body movements in space and time to achieve a joint goal. Animations of interacting action pairs (partners in human interactions) and non-interacting action pairs (individual actors sampled from different interaction sequences) were shown in the experiment. Participants were asked to rate how likely th...

Hierarchical coalitions are organisations whose components carry out different planning and plan execution activities at each level. One of the principal aims of knowledgebased tools for coalitions is to support such components so that they are able to work synergically together, each of them accounting for part of the planning and execution process. The use of planning assistant agents is an a...

Introduction: Proper anteroposterior (AP) joint displacement is an important indicator of good clinical outcome following total knee arthroplasty (TKA). Although anesthesia would tend to exclude the contributions of voluntary soft tissue tension, its effect on knee-joint displacement has not been studied in TKA, although it has been studied in the repair of the anterior cruciate ligament. Addit...

In this paper, by utilizing fixed-time control technique and a leader-follower scheme, three-dimensional (3-D) cooperative guidance law is developed to tackle impact angle constrained simultaneous arrival problem. Firstly, in the line-of-sight (LOS) direction, command for leader put forward make time error converge zero fixed such that capable of reaching target at prespecified time. Then, each...
