This paper investigates a fundamental problem of determining the position, orientation, and velocity field of the Gulf Stream in time-varying imagery. We propose an approximation method to characterize the deformation of these image motions for the purpose of estimating the velocity field of these images. The technique is focused on the interpretation of the change in the extracted features of ...

With the increasing use of sensor devices, machine-to-machine communications, and social networks there are large volumes of real world data that are multi-modal, dynamic and heterogeneous. Among the main challenges of the Internet of Things, Social Media Analytics and their blending in CyberSocial-Physical Systems is how to deal with large volumes of sensory and social data, and how to extract...

Exercise I. Optimization of a heater. We want to optimize the temperature T of a room Ω by the mean of a heater ω whose heat flux v ∈ L(ω) is controlled. An air stream of velocity u fills the room. We assume that the air is incompressible, that is u is assumed to be divergence free. Moreover, u is also assumed to be regular. The temperature on the boundary of the room is equal to the external t...

the present paper deals with the prediction of three-dimensional fluid flow and heat transfer in rib-roughened ducts of square cross-section. such flows are of direct relevance to the internal cooling system of modern gas turbine blades. the main objective is to assess how a recently developed variant of a cubic non-linear model (proposed by craft et al. (1999)), that has been shown to produce ...

The flow of a gaseous fluid past a rigid, smooth half-plane, parallel to the asymptotic velocity of the stream, is studied. The edge of the half-plane (leading edge) is assumed to be orthogonal to the stream, and, in addition, it is assumed that the flow is everywhere "turbulent". The motion within the boundary layer is investigated in an attempt to clarify many of the assumed and conjectured f...

background : the application of ventilation systems in industries and workplaces is with the aim of improving environmental conditions for employees. the lack of appropriate ventilation system components design and control methods result in the production of sound and vibration in most components. the purpose of this study was to determine the role of the pad isolator in controlling vibration a...

Exercise I. Optimization of a heater. We want to optimize the temperature T of a room Ω by the mean of a heater ! whose heat flux v ∈ L(!) is controlled. An air stream of velocity u fills the room. We assume that the air is incompressible, that is u is assumed to be divergence free. Moreover, u is also assumed to be regular. The temperature on the boundary of the room is equal to the external t...

Pc3 geomagnetic ®eld ̄uctuations detected at low latitude (L'Aquila, Italy) during the passage of a high velocity solar wind stream, characterized by variable interplanetary magnetic ®eld conditions, are analyzed. Higher frequency resonant ̄uctuations and lower frequency phenomena are simultaneously observed; the intermittent appearance and the variable frequency of the longer period modes can ...
