Vent opening hazard models are routinely used as inputs for assessing distal volcanic hazards (lava flows, tephra fallout) in distributed fields. These vent have traditionally relied on the location of mapped vents; seldom they taken into account how vents linked space and time. We show that needed to appropriately model fundamentally different than thoses required near-vent (ground deformation...

Skin cancer has become the most common type. Research applied image processing and analysis tools to support improve diagnose process. Conventional procedures usually centralise data from various sources a single location execute tasks on central servers. However, centralisation of medical does not often comply with local protection regulations due its sensitive nature loss sovereignty if provi...

The algebra for distributed data sources includes standard operations on sets which evolved from the relational and nested-relational algebras, the operations for querying the conceptual schemata, and the operations which allow for the manipulation of distributed objects. The algebra serves as the basis for the prototype implementation of the query optimizer for distributed data sources. The de...

Abstmet-ost array pmcsssing algorithms are based on the assumption that the signals are generated by point munxs. Tbis is a mathematical constraint that is not sattpeed in mnny applications In thh paper, we consider situations where the sources are distributed in space with a parametric angular c m correlation kernel. We propose an algorithm that estimates the parameters of thh model using a...
