We present a model that can automatically learn alignments between high-dimensional data in an unsupervised manner. Learning alignments is an ill-constrained problem as there are many different ways of defining a good alignment. Our proposed method casts alignment learning in a framework where both alignment and data are modelled simultaneously. We derive a probabilistic model built on non-para...

This paper describes a STLTSA-based framework to analyze and decompose human motion for synthesis. In this work, we mainly intend to extend a manifold learning method, local tangent space alignment, to a spatio–temporal version for manifold analysis and offer an effective method of estimating the intrinsic dimensionality of motion data. Based on an assumption that a long sequence of motion is c...

Accurate image alignment is needed for computing three-dimensional reconstructions from transmission electron microscope tilt series. So far, the best alignment results have been obtained by using colloidal gold beads as fiducial markers. If their use has not been possible for some reason, the only option has been the automatic 2D-crosscorrelation-based registration methods. However, since the ...

introduction: acinetobacter baumannii is associated with hospital-acquired infections. outer membrane protein a of a.baumannii (abompa) is a well-characterized virulence factor which has important roles in pathogenesis of this bacterium. methods: based on our pcr-sequencing of ompa gene in the clinical isolates, abompa protein can be categorized into two types, named here type-1 and type-2. we ...

BACKGROUND Articulated or hinged ankle-foot orthosis (AFO) allow more range of motion. However, quantitative investigation on articulated AFO is still sparse. OBJECTIVE The objective of the study was to quantitatively investigate effects of alignment and joint types on mechanical properties of the thermoplastic articulated AFO. STUDY DESIGN Tamarack dorsiflexion assist flexure joints with t...

Achieving business-IT alignment is one of the main purposes and also challenges of organizations. Many studies have indicated the importance of aligning information systems (IS) function with other business functions. The main purpose of this survey is evaluating business-IT alignment focusing on social and technical dimensions of business-IT alignment in Bank Mellat. The data was collected thr...

bioinformatics, through the sequencing of the full genomes for many species, is increasingly relying on efficient global alignment tools exhibiting both high sensitivity and specificity. many computational algorithms have been applied for solving the sequence alignment problem. dynamic programming, statistical methods, approximation and heuristic algorithms are the most common methods applied t...

Many application areas such as semiconductor manufacture, precision optics alignment, and microbiological cell manipulation require ultraprecision positioning systems with a high positioning resolution and large motion range. This article describes the development of a compact high precision linear piezoelectric stepping positioner for precision alignment of optical elements. The positioner is ...
