Artifact-centric workflows describe possible executions of a business process through constraints expressed from the point of view of the documents exchanged between principals.
This model helps in assessing tactical decisions through constraints that force each collection area to be capacitated enough to fit the expected waste to be directed to that area, while taking into account Quality of Service constraints from the citizens' point of view.
In [15], the authors proposed to perform power control following an probabilistic interference constraint, which is derived from the point of long term statistics of the interference power.
This analysis is performed in relation with some ergonomic constraints from the operator point of view.
Optimal power allocation at the senor transmitters for such outage minimization under various types of transmit power constraints is an important problem from the point of view of reducing energy consumption in sensor networks, or equivalently, prolonging the lifetime of the network.
From the point of view of constraint conditions, it is in fact a mathematical program with equilibrium constraints (MPEC) [10 13].
From the point of view of constraint conditions, it is not easy to get solutions due to the equilibrium constraints, as well as the discontinuous objective function.
Then, from the point of the practical constraints of a GNSS receiver on the earth surface, a new formula for the specific minimum of GDOP together with the design matrix is derived.
Co-variation among life-history traits has been the centre of much research in the past decades in the context of adaptive evolution as well as from the point of view of constraints on this evolution due to trade-offs between traits [ 24- 29], and the existence of syndromes encapsulating dispersal strategies has been hypothesized [ 21, 23, 30, 31].
From the point of view of the two main challenges, intensified environmental constraints and systemic crisis, results are below expectations.
