The administrator of current IT environments is facing a continuous increase in the complexity that s/he needs to handle. S/he can be compared to a power jet pilot sitting in front of a console with a plenty of gouges, leds, counters, each of them measuring or showing a particular part of the overall aircraft status. The pilot looks to all these indications, correlate each other these data sour...

In this article, the historical use of crafts in occupational therapy for the physically disabled patient is reviewed and the results of a survey aimed at describing current craft use is presented. A questionnaire was sent to a random sample of 250 occupational therapists throughout the United States who chose physical disabilities as their specialty section. Results demonstrated that, while mo...

O way to organize workers that lies between traditional assembly lines, where workers are specialists, and craft assembly, where workers are generalists, are “bucket brigades.” We describe how one firm used bucket brigades as an intermediate strategy to migrate from craft assembly to assembly lines. The adoption of bucket brigades led to a narrowing of tasks for each worker and thus accelerated...

Self propelled models under radio control have been used for many years to assess the manoeuvring and handling of ships, and occasionally small craft. The limitations for testing small, fast craft have been linked to the low model weight required and the ability to install enough power, as well as the cost of modelling. Recent advances in motor and battery technology, the availability of model ...

In this work we propose a family of trajectory tracking controllers for marine craft in the port-Hamiltonian (pH) framework using virtual differential passivity based control (v-dPBC). Two pH models of marine craft are considered, one in a body frame and another in an inertial frame. The structure and workless forces of pH models are exploited to design two virtual control systems which are rel...

Peer-to-Peer (P2P) can support service for lots of end users with little hardware investment, which suits for the efforts to lower down the service cost for Multiplayer Online Games (MOG). In this paper, we introduce PKTown, a P2P middleware inserted into Star Craft and the network layer. PKTown captures all packets generated by Star Craft. Application Layer Multicast (ALM) is a popular techniq...

The creation of useful artefacts with rich experiential qualities required quality driven interaction designers and programmers with the ability to simultaneous problem setting and problem solving. Interaction design is a design practice that defines the appearance and function of digital artefacts. Bridging interaction design and engineering is problematic because design and engineering have d...
