In this paper we introduce the optimal solution for a simple and yet practical inventory policy with the important characteristic which eliminates the uncertainty in demand for suppliers. In this new policy which is different from the classical inventory policies, the time interval between any two consecutive orders is fixed and the quantity of each order is one. Assuming the fixed ordering cos...

Multichannel techniques offer advantages in noise reduction and overall output signal quality when compared to the well studied mono approaches. In this paper we present an original multichannel psychoacoustically motivated noise reduction algorithm that naturally extends the single channel psychoacoustic masking filter previously studied in the literature [1]. The optimality criterion is desig...

Bio-logging is a useful technique for obtaining information on foraging behaviour, physiology, and environmental conditions from animals in marine ecosystems. By integrating this information, researchers can investigate the ecology of general prey-predator system in terms of their optimal behaviour with the help of theoretical models. In the present study, I analyse the diving behaviour of two ...

We generalized a modified exponentialized estimator by pushing the robust-optimal (RO) index λ to −∞ for achieving robustness to outliers by optimizing a quasi-Minimin function. The robustness is realized and controlled adaptively by the RO index without any predefined threshold. Optimality is guaranteed by expansion of the convexity region in the Hessian matrix to largely avoid local optima. D...

We investigate the general multi-armed bandit problem with multiple servers. We determine a condition on the reward processes su1⁄2cient to guarantee the optimality of the strategy that operates at each instant of time the projects with the highest Gittins indices. We call this strategy the Gittins index rule for multi-armed bandits with multiple plays, or brie ̄y the Gittins index rule. We show...

The main objective of this paper is to propose a more efficient, distributed, and multi-objective billing model that can be implemented in every smart meter the grid for achieving optimality fairness. First, we develop new evaluation index evaluate such as not only addressing fairness but also minimize cost reduce Peak-to-Average Ratio (PAR) load demand subsequently bill each customer. Then, st...

the realization optimality theory is a recent development in the original optimality theory which is proposed to deal with morphological issues especially the inflectional ones. its main idea is to consider the morphological realization rules as ranked violable language-specific constraints that control the realization processes and provide phonological information of grammatical morphemes. thi...

Partial clique covering is one of the most basic coding schemes for index coding problems, generalizing clique and cycle covering on the side information digraph and further reducing the achievable broadcast rate. In this paper, we start with partition multicast, a special case of partial clique covering with cover number 1, and show that partition multicast achieves the optimal broadcast rate ...
