Packet Tracer uses two representation schemes to represent a network: logical workspace and physical workspace. In this paper, our implementation uses these two schemes to build networks and to demonstrate our experiments. Logical workspace is used to build a logical topology and physical workspace is used to arrange devices physically. Packet Tracer as demonstrated in this paper has an operati...

Most interfaces for switching between tasks require slow, visual searches of candidates, where each candidate must be scanned in turn. We developed a logging tool for task switching actions and undertook a log-based study with eleven participants to empirically characterise task-switching behaviour, finding Zipfian distributions for window and application switching, and significant differences ...

Doty Professor in Electrical Engineering 515 Weil Hall Machine Intelligence Laboratory Department of Electrical Engineering University of Florida Gainesville, FL 32611 Telephone: (904)392-4951 email: [email protected] email: [email protected] ABSTRACT This paper develops a symbolic method for calculating a manipulator’s singularity manifold in configuration space. The concept of spatial ...

In this paper, evolving takagi-sugeno fuzzy models are applied to model a dynamic system, e.g. a six degrees of freedom robotic manipulator. In recent years the dynamic model was obtained off-line, but when the robot performs tasks away from the modeled workspace, it fails in achieve the goal. Then, the models must evolve when the robot moves to a previously un-modeled workspace. The models wer...

It has been hypothesised that a global neuronal workspace underlies the brain's capacity to process information consciously. This paper describes a significant variation on a previously reported computer simulation of such a global neuronal workspace, in which competition and broadcast were realised through reverberating populations of spiking neurons. In the present model, unlike the previous ...

Workspace awareness has emerged as a new coordination paradigm in software configuration management systems, enabling the early detection of potential conflicts by providing developers with information of relevant, parallel activities. The focus of our particular research in workspace awareness has been on detecting and mitigating both direct and indirect conflicts by unobtrusively sharing info...

We dispel with “street wisdom” regarding the practical implementation of Strassen’s algorithm for matrix-matrix multiplication (DGEMM). Conventional wisdom: it is only practical for very large matrices. Our implementation is practical for small matrices. Conventional wisdom: the matrices being multiplied should be relatively square. Our implementation is practical for rank-k updates, where k is...

Computer simulations aimed at assessing functional characteristics of the graphic workspace are presented. The simulations involve a 10-df kinematic model of the distal part of the writing arm, and yield the effective workspace of the pen tip under two types of kinematic constraints. The first constraint involves fixing the forearm under various pronation angles, the second governs the protrusi...

Nowadays, many teams collaborate via shared workspace environment which offer a suite of services supporting the group interaction. The needs for an effective group interaction vary over time and are dependent of the current problem and group goal. An ideal shared workspace environment has to take this into account and offer means for tailoring the offered the services to meet the current needs...

In this paper, we study the design and workspace of a 6–6 cable-suspended parallel robot. The workspace volume is characterized as the set of points where the centroid of the moving platform can reach with tensions in all suspension cables at a constant orientation. This paper attempts to tackle some aspects of optimal design of a 6DOF cable robot by addressing the variations of the workspace v...
