چکیده
Actor: Entity (human or computer) possessing a capability to act intelligently and process specific assignments (activities/tasks). Atomic task: Task that can be handled by an individual actor. CAS: Collective adaptive system. Collaboration system (platform): Information system supporting execution of collaborative processes. Collaborative process (collaboration): Joint effort of a (limited) number of actors with the goal of performing a task. A collaborative process has a limited duration and requires coordination among actors (due to task dependencies). Composite task: Task that must be handled by multiple actors due to size or complexity. A composite task can be broken down into atomic tasks. CSCW: Computer-supported cooperative work. HBS: Human-based service. Metric: Precisely defined, context-specific measure of some properties. QoD: Quality of data. QoS: Quality of service. SOA: Service-oriented architecture. SOC: Service-oriented computing. Task assignment: The art to divide a (composite) task into (sub)tasks and assign

The design of many information processing systems rely on representative samples of data. Such data may not be readily available due to the cost of acquiring the data or due to privacy concerns. This situation can be alleviated by constructing representative samples from available data sets. This can be done by applying appropriate transformations, e.g., injecting noise, that preserve semantic ...
متن کاملExtrapolation of vector valued rearrangement operators
Given an injective map τ : D → D between the dyadic intervals of the unit interval [0, 1), we study extrapolation properties of the induced rearrangement operator of the Haar system IdX ⊗ Tp,τ : L p X,0([0, 1)) → L p X([0, 1)), where X is a Banach space and L p X,0 the subspace of mean zero random variables. If X is a UMD-space, then we prove that the property that IdX ⊗ Tp,τ is an isomorphism ...
متن کاملExtrapolation of vector-valued rearrangement operators II
We determine the extrapolation law of rearrangement operators acting on the Haar system in vector valued H spaces: If 0 < q ≤ p < 2, then, ‖Tτ,q ⊗ IdX‖ q 2−q q ≤ A(p, q)‖Tτ,p ⊗ IdX‖ p 2−p p . For a fixed Banach space X, the extrapolation range 0 < q ≤ p < 2 is optimal. If, however, there exists 1 < p0 < ∞, so that ‖Tτ,p0 ⊗ IdE‖L0 E < ∞, for each UMD space E, then for any 1 < p < ∞, ‖Tτ,p ⊗ IdE‖...

In this paper we give estimates of tails and moments of multidimensional chaoses P ai1,...,idX (1) i1 · · ·X id (ai1,...,id ≥ 0) generated by positive random variables X (1) i1 , . . . , X (d) id with logarithmically concave tails. The estimates are exact up to constants depending only on the dimension d.
