This paper presents an adaptive peak frequency estimation method using a database that stores PARCOR coefficients as key attributes and the corresponding peak frequencies as nonkey attributes. The least-square lattice algorithm is used to recursively estimate the PARCOR coefficients to adapt to changing circumstances. The nearest neighbor to the current PARCOR coefficient is retrieved from the ...

In recent years a swarm-based optimization methodology called Particle Swarm Optimization (PSO) has developed. If one wants to apply PSO one has to specify several parameters as well as to select a neighborhood topology. Several topologies being widely used can be found in literature. This raises the question, which one fits best to your application at hand. To get rid of this topology selectio...

Many problems reduce to the fixed-point problem of solving x = T (x), where T is a mapping from a Hilbert space to itself. To this problem, we apply the coordinate-update algorithms, which update only one or a few components of x at each step. When each step is cheap, these algorithms are faster than the full fixed-point iteration (which updates all the components). In this paper, we focus on c...

The impact of an amino acid replacement on the organism's fitness can vary from lethal to selectively neutral and even, in rare cases, beneficial. Substantial data are available on either pathogenic or acceptable replacements. However, the whole distribution of coefficients of selection against individual replacements is not known for any organism. To ascertain this distribution for human prote...

In this paper, we propose a real-time adaptive prediction method to calculate smooth and accurate haptic feedback in complex scenarios. Smooth haptic feedback is an important task for haptic rendering with complex virtual objects. However, commonly the update rate of the haptic rendering may drop down during multi-point contact in complex scenarios because high computational cost is required fo...

Large populations with extensive breeding distributions may sustain greater genetic variability, thus producing a positive relationship between genetic variation and population size. Levels of genetic variability may also be affected by sexual selection, which could either reduce levels because a small fraction of males contribute to the following generation, or augment them by generating genet...

Several XML update languages have been developed in recent years, trying to fill a gap that was left behind by XML query and transformation languages. XML Update languages provide both an efficient and comfortable way of updating XML data, for which XML transformation languages are not feasible. One of them is the update language introduced as a part of the reactive language XChange. XChange’s ...
