We present a theoretical model describing the dynamics of the electromagnetic field in an optical resonator undergoing refractive index changes. We use an operator formulation of Maxwell’s equations with a standard timedependent perturbation theory to derive the dynamic mode-amplitude equations that govern the response of a resonator to a perturbing dipole-moment density. We show that in the ca...

Since the introduction of the h-index in 2005 (Hirsch, 2005), many h-type indices have been proposed. In this short note, we propose yet another h-type index, which differs from other proposals in the way that it takes recent change in the value of the h-index into account. As such, we are convinced that this proposal is more useful for hiring purposes than the lifetime-achievement h-index. For...

A new dynamic multi-dimensional index structure called RSR-tree is proposed, in which splitting operations of leaf nodes and non-leaf nodes are performed separatively. RSR-tree retains the sequence ordering of index records in a leaf node of RS-tree and thus reduces the addressing time cost of disk access while reading data files. In addition, it integrates the characteristic of reducing the ov...

Baltic Exchange Dry Index (BDI) is an independent response of maritime market information for the trading and settlement of physical and derivative contracts. In this paper, we propose fuzzy set theory and grey system for modeling the prediction of BDI, and employ the ARIMA model for the calibration of the data structure to depict the trend. The empirical results indicate that for both short-te...

The problem of indexing multidimensional objects is considered. First, a classification of existing methods is given along with a discussion of the major issues involved in multidimensional data indexing. Second, a variation to Guttman’s R-trees (R+-trees) that avoids overlapping rectangles in intermediate nodes of the tree is introduced. Algorithms for searching, updating, initial packing and ...

We present a new technique for measuring refractive index changes using the technique of phase-shift keying of holographic gratings. Based on this technique, we have realized an holographic interferometer to gauge refractive index variations in gases. We present experimental data for standard atmosphere under laboratory conditions and theoretical calculations for the measured transfer function ...

Taiwan’s special climate and landforms are affected by summer typhoons, with 78% of its rainfall occurring during the summer and autumn months. The range and the severity of disasters has increased in recent years, thanks in part to climate change, which has caused an unstable rainfall. Accurate rainfall predictions help to forecast rivers’ water levels. This study proposes a new rainfall predi...

This paper presents a brief introduction to the emerging research field of multi-armed restless bandits (MARBs), which substantially extend the modeling power of classic multi-armed bandits. MARBs are Markov decision process models for optimal dynamic priority allocation to a collection of stochastic binary-action (active/passive) projects evolving over time. Interest in MARBs has grown steadil...

This paper presents a realistic study of applying a gene regulatory model to financial prediction. The combined adaptation of evolutionary and developmental processes used in the model highlight its suitability to dynamic domains, and the results obtained show the potential of this approach for real-world trading.
