PAMDI is an electromechanical music controller based on an expansion of the common metal music boxes. Our system enables an augmentation of a music box by adding different musical channels triggered and parameterized by natural gestures during the “performance”. All the channels are generated from the original melody recorded once at the start. We made a platform composed of a metallic structur...

In the field of e-learning, a popular solution to make teaching material reusable is to represent it as learning object (LO). However, building better adaptive educational software also takes an explicit model of the learner’s cognitive process related to LOs. This paper presents a three layers model that explicitly connect the description of learners’ cognitive processes to LOs. The first laye...

Virtualization can provide significant benefits in data centers by enabling virtual machine migration to eliminate hotspots. We present Sandpiper, a system that automates the task of monitoring and detecting hotspots, determining a new mapping of physical to virtual resources and initiating the necessary migrations. Sandpiper implements a black-box approach that is fully OSand application-agnos...

Military Operations Research makes extensive use of large complex simulation models. These simulation models are often black-boxes; i.e. they are opaque and incomprehensible. A considerable effort is involved in commissioning a new model into service. We characterise this activity as the construction of gray-box approximate causal models of the functional behaviour of black-box simulation softw...

introduction: rural areas are affected by globalization and one of the globalization commitments. wto accession creates both benefits and expenditures for countries especially rural societes in new member, but preponderance of created benefits and expenditures depends on country bargaining power in negotiation process and agreement acceptation. as there is not independent and separate agreement...
