Biological pairwise sequence alignment can be used as a method for arranging two biological characters to identify regions of similarity. This operation has elicited considerable interest due its significant influence on various critical aspects life (e.g., identifying mutations in coronaviruses). Sequence over large databases cannot yield results within reasonable time, power, and cost. heuris...

BACKGROUND While trying to integrate multiple data sets collected by different researchers, we noticed that the sample names were frequently entered inconsistently. Most of the variations appeared to involve punctuation, white space, or their absence, at the juncture between alphabetic and numeric portions of the cell line name. RESULTS Reasoning that the variant names could be described in t...

A new technique for measuring the elastic-plastic properties of porous thin films by means of nanoindentation is proposed. The effects of porosity on indentation hardness and modulus are investigated through finite element analyses based on the Gurson model for plastic deformation of ductile porous materials. Intrinsic mechanical properties of the thin film are obtained by eliminating both subs...

Algorithm and scoring parameters Eg ”best” Two methods for searching protein and DNA Evolution of protein and DNA sequence is done using database. 1. Local comparison i) Ignoring difference-outside most similar region ii) Find similarity between two sequence 2. Gobal Comparison. More appropriate when homology has been established when Building evolutionary trees comparison methods are preferred...

The local approach to fracture (LAF) is a methodology aimed to calculate macroscopic fracture properties of a body, from the knowledge of the local stress strain field at the fracture site, and the modeling of the acting fracture mechanisms. In the present work, this method was applied to a CF8M steel, aged 30000 h at 325 °C, in order to elucidate if LAF could be able to describe the measured f...

We present a new machine learning approach to the inverse parametric sequence alignment problem: given as training examples a set of correct pairwise global alignments, find the parameter values that make these alignments optimal. We consider the distribution of the scores of all incorrect alignments, then we search for those parameters for which the score of the given alignments is as far as p...

Both in interactive music listening, and in music performance research, there is a need for automatic alignment of different recordings of the same musical piece. This task is challenging, because musical pieces often contain parts that may or may not be repeated by the performer, possibly leading to structural differences between performances (or between performance and score). The most common...

We present a general algorithm to align two protein sequences that uses the concept of don't care regions. It is based on the classical Needleman-Wunsch dynamic programming method using aane penalty functions. We tested the algorithm on two problems, comparing it against the standard dynamic programming algorithm. Results were not consistently or signiicantly better, suggesting that reenements ...

The continuous and rapid advent in mobile and communications technology opens the way for new research areas and new applications. Moving Object Databases(MODs) are among the emerging research topics that are attracting many work due to their vital need in many applications. Generally, MODs deal with geometries changing over time. In this paper we study an interesting point in moving object dat...
