Computational models of protein structures were proved to be useful as search models in Molecular Replacement (MR), a common method to solve the phase problem faced by macromolecular crystallography. The success of MR depends on the accuracy of a search model. Unfortunately, this parameter remains unknown until the final structure of the target protein is determined.

This paper proposes an analytical model which covers full specification of IEEE 802.11e EDCA. To reduce the complexity, the model is simplified by decomposing the problem in two models based on Markov chain that can be easily solved by numerical method. The proposed model is presented in the theoretical aspect as well as numerical results to clarify its accuracy.

The field of packet classification speed enhancement has attracted a significant number of researchers. In this paper, we propose a packet classification algorithm based on the idea of priority trie and multi-way trie. The accuracy and efficiency of the proposed algorithm are both theoretically and experimentally proved.

Several important tendencies have been emerging recently in the NLP community. First of all, work on corpora tends to become the norm, which constitutes a fruitful convergence area between taskdriven, computational approaches and descriptive linguistic ones. On corpora validation becomes more and more important for theoretical models, and the accuracy of these models can be evaluated either with regard to their ability to account for the reality of a given corpus (pursuing descriptive aims), either with regard to their ability to analyse it accurately (pursuing operational aims). ...

Previous studies of data-driven dependency parsing have shown that the distribution of parsing errors are correlated with theoretical properties of the models used for learning and inference. In this paper, we show how these results can be exploited to improve parsing accuracy by integrating a graph-based and a transition-based model.

This book presents a mathematical development of a recent approach to the modeling and simulation of turbulent flows based on methods for the approximate solution of inverse problems. The resulting Approximate Deconvolution Models or ADMs have some advantages (as well as some disadvantages) over more commonly used turbulence models: ADMs are supported by a mathematically rigorous theoretical foundation. ADMs are a family of models of increasing accuracy O(δ2N+2), where δ is the averaging (or filter) radius...

Calibration is the most important step in bioactive compound analysis. A good Precision and accuracy can only be obtained when a good calibration procedure is adopted. In the Spectrophotometric methods, the concentration of a sample cannot be measured directly, but is determined using physical measuring quantity ‘y’ (absorbance of a solution). An unambiguous empirical or theoretical relationship can be shown between this quanity and the concentration of an analyte.

This volume aims to provide the fundamental knowledge to appreciate the advantages of the J-matrix method and to encourage its use and further development. The J-matrix method is an algebraic method of quantum scattering with substantial success in atomic and nuclear physics. The accuracy and convergence property of the method compares favourably with other successful scattering calculation methods. Despite its thirty-year long history new applications are being found for the J-matrix method.
