The problem of bicriterion scheduling of jobs with identical processing times by uniform processors is considered. The first criterion is the minimization of either total or maximum costs, the second one is the minimization of maximum cost with different cost functions. Polynomial time algorithms are presented to determine all efficient solutions and the optimal solution for a given global crit...

In many global optimization problems motivated by engineering applications, the number of function evaluations is severely limited by time or cost. To ensure that each of these evaluations contributes to the localization of good candidates for the role of global minimizer, a sequential choice of evaluation points is usually carried out. In particular, when Kriging is used to interpolate past ev...

Data-based control design methods most often consist of iterative adjustment of the controller’s parameters towards the parameter values which minimize an H2 performance criterion. Typically, batches of input-output data collected from the system are used to feed directly a gradient descent optimization no process model is used. A limiting factor in the application of these methods is the lack ...

Wiener amalgam spaces are a class of spaces of functions or distributions defined by a norm which amalgamates a local criterion for membership in the space with a global criterion. Versions of such amalgam spaces have arisen independently many times in the literature, and often provide a natural and compelling context for formulating results. As one illustration of the shortcomings of the usual...

Suucient conditions of existence and global asymptotic stability of a limit cycle induced by a relay with hysteresis feedback in a linear time-invariant stable system are derived. The criterion is based on inspection of the open loop step response, combined with estimations of certain measures of its variance. Unlike the well-known describing functions method, the proposed approach yields a rig...

In this paper, we introduce Quasi Serializability, a correctness criterion for concurrency control in heterogeneous distributed database environments. A global history is quasi serializable if it is (conflict) equivalent to a quasi serial history in which global transactions are submitted serially. Quasi serializability theory is an extension of serializability. We study the relationships betwe...
