Using mobile devices enhances overall collaboration and communication between team workers. Co-workers can collaborate and share content regardless of their location. Workflow management is a widely accepted technology that supports collaboration; however, existing workflow approaches provide only a limited support for content management. Moreover, constantly changing collaborators’ contexts an...

An efficient probabilistic algorithm for the concurrent mapping and localization problem that arises in mobile robotics is presented. The algorithm addresses the problem in which a team of robots builds a map on-line while simultaneously accommodating errors in the robots’ odometry. At the core of the algorithm is a technique that combines fast maximum likelihood map growing with a Monte Carlo ...

We present a distributed planar object manipulation algorithm inspired by human behavior. The system, which we call pusher-watcher, enables the cooperative manipulation of large objects by teams of autonomous mobile robots. The robots are not equipped with gripping devices, but instead move objects by pushing against them. The pusher robots have no global positioning information, and cannot see...

Nowadays, process-aware information systems (PAISs) are widely used for the management of “administrative” processes characterized by clear andwell-defined structure. Besides such scenarios, PAISs can be used also in mobile and pervasive scenarios, such as in coordinating operators during emergency situations [1]. In these pervasive settings, due to highlymobility, operators have to be equipped...

The objective of this study was to describe our NICU’s (neonatal intensive care unit) experience with mobile surgical team and to demonstrate its effectiveness. Method: We analyzed the data of 17 consecutive very low birth weight and extremely low birth weight infants over 3 years who underwent 22 procedures (19 emergency and 3 elective). The gestational age at birth was a median of 25 weeks (r...

Globalization, customer-specific bundling of expertise and the consideration of expertise as “intellectual assets” are taking place in the financial sector all together. This enables new forms of mobile workspaces, which cover the whole value chain from the formation of a service team within an organization, the generation of information to solve problems and the seamless support for the expert...

The paper deals with appropriate calibration of multispectral vision systems and evaluation of the calibration and data-fusion quality in real-world indoor and outdoor conditions. Checkerboard calibration pattern developed by our team for multispectral calibration of intrinsic and extrinsic parameters is described in detail. The circular object for multispectral fusion evaluation is described a...

We consider a team of mobile robots equipped with sensors and wireless network cards and the task of navigating to a desired location in a formation. We develop a set of algorithms for (a) discovery; (b) cooperative localization; and (c) cooperative control. Discovery involves the use of sensory information to organize the robots into a mobile network allowing each robot to establish its neighb...

In this paper we extend our results (as given in [PHE+07]) concerning the layered architecture for modeling workflows in Mobile Ad-Hoc NETworks (MANETs) using algebraic higher order nets. MANETs are networks of mobile devices that communicate with each other via wireless links without relying on an underlying infrastructure. Workflows in MANETs can be adequately modeled using a layered architec...

CONTEXT Our medical team of 12 people conducted a series of mobile health clinics sponsored by an indigenous relief organization in rural Ethiopia. Coordinating with local health authorities, the purpose of these clinics was to provide acute care medical treatment and public health teaching. ISSUE Initially, we used a 'pre-triage' process that had evolved over a series of previous rural mobil...
