Understanding intentionality is a necessary feature of joint activities involving interdependent agents. This challenge has increased alongside the deployment of autonomous systems that are to some degree unsupervised. This research aims to reduce the number of intentionality recognition breakdowns between people and autonomous systems by designing systems to support the awareness of informatio...

During crisis situations, teams are more prone to coordination breakdowns that characterized by a temporary, diminished ability function effectively as team. However, team research currently lacks robust approaches for identifying transitions from effective functioning breakdowns. With the current study, we aimed develop such approaches, and deepen our understanding of how dynamics across vario...

Breakdowns have variantly been described as symptoms or causes of difficulties in the design process [4], instances that lead to the reframing of problems [3], or in a more general sense, as occurrences of object/idea emergence [7], to mention a few. They seem to play a large role in design behaviour. They directly affect the decision making process and subsequently the course of action, and vi...

This paper presents a comparative analysis of communicative breakdowns experienced by participants collaboratively performing a task in three communication environments: face-to-face, mediated by an audio connection, and mediated by both an audio and a video connection. A quantitative analysis showed significantly less breakdown in the copresent condition than in either of the two technological...

A single server finite population queueing model with compulsory server vacation and with fixed batch service has been considered. For this model the system steady state probabilities are obtained. Some performance measures are calculated and numerical examples are also given.  

in this paper a single server queuing production system is considered which is subject to gradual deterioration. the system is discussed under two different deteriorating conditions. a planning horizon is considered and server which is a d/m/1 queuing system is gradually deteriorates through time periods. a maintenance policy is taken into account whereby the server is restored to its initial c...

After giving an overview over various conservation law models for supply networks, this talk will focus on level set approaches to modeling scheduling policies in supply chains. The starting point is a rather high dimensional kinetic model for a density of parts / particles with multidimensional attributes. After deriving hyperbolic conservation laws for the level sets of all parts with equal s...

In this paper, we investigate human visual perception and establish a body of ground truth data elicited from human visual studies. We aim to build on the formative work of Ren, Eakins and Briggs who produced an initial ground truth database. Human subjects were asked to draw and rank their perceptions of the parts of a series of figurative images. These rankings were then used to score the per...
