A component is a self contained entity that interacts with its environment through well-definedinterfaces. The component library Fractive provides high level primitives and semantics for program-ming Java applications with distributed, asynchronous and hierarchical components. It also providesa separation between functional and non-functional aspects, the latter allows the execution...

Navigation Experiment: This research aims to investigate the possibility of using an alternative, infrared based sensor system, for planetary rovers required to operate autonomously in environments with challenging terrain. For this research, computer models of a planetary rover and Martian environment have been constructed using the ODE physics engine. The control system for the robot consists...

this systematic review intended to combine factors associated with tuberculosis treatment non-adherence and lost to follow up among tb patients with/without hiv in developing countries. comprehensive remote electronic databases (medline, (pmc, pub med central), google scholar and web of science) search was conducted using the following keywords: tuberculosis, treatment, compliance, adherence, d...

Within the framework of Supervisory Control Theory, synthesis algorithms enable automatic generation of control rules from behavioural models of the process to be controlled and of goals to be achieved. This paper talks about a pragmatic use of these algorithms within an automation engineering context and focuses on two key issues: process and goals modelling and supervisory controller implemen...

Novelty search is an algorithm which proposes open-ended exploration of the search space by maximising behavioural novelty, removing the need for an objective fitness function. However, we show that when applied to complex tasks, training through novelty alone is not sufficient to produce useful controllers. Alongside this, the definition of phenotypic behaviour significantly effects the strate...

This paper presents a solution for the behavioural animation of autonomous virtual agent navigation in virtual environments. We focus on using Dempster-Shafer’s Theory of Evidence in developing visual sensor for virtual agent. The role of the visual sensor is to capture the information about the virtual environment or identifie which part of an obstacle can be seen from the position of the virt...

In distributed computing, the leadership election has been used to distributively designate a node as the central controller (leader) of a network of nodes. The complexity of the algorithm arises due to the unawareness of every node of who the current leader is. After running the algorithm, however, a unique node in the network must be elected as the leader and recognized as so by the remaining...

During goal-directed decision-making, animals must integrate information from the external environment and their internal state to maximize resource localization while minimizing energy expenditure. How this complex problem is solved by the nervous system remains poorly understood. Here, using a combined behavioural and neurophysiological approach, we demonstrate that the mollusc Lymnaea perfor...

We present an extended framework for modelling agent-object interactions in virtual environments. Our framework is based on the concept of Smart Objects and provides agents with pre-programmed interaction information for the automatic generation of animations. The ability to generate such animations without human intervention is vital when constructing plausible, real-time agents. Unlike previo...
