Damage identification by Lévy ant colony optimization

2010

This paper deals with the identification of incipient damage in structural elements by non-destructive test based on experimentally measured structural dynamical response. By applycation of the Hilbert transform to the recorded signal the so-called phase of the analytical signal is recovered and a proper functional is constructed in such a way that its global minimum gives a measure of the damage level, meant as stiffness reduction. Minimization is achieved by applying a modified Ant Colony Optimization (ACO) for continuous variables, inspired by the ants’ forageing behavior. The modification consists in the application of a new perturbation operator, based on alpha stable Lévy distribution…

Invalid Syntax: NooJ Assisted Automatic Detection of Errors in Auxiliaries and Past Participles in Italian

2017

The work targets two areas of Italian morphosyntax: auxiliary selection (AS) and past participle agreement (PPA). In selecting such inflectional morphemes, learners of Italian commit frequent errors, even after a long period of constant study. We aim to enclose AS and PPA within the boundaries of NLP in order that a tool can be developed with a twofold purpose: first, it helps experts to build specific computer drills regarding AS and PPA; second, it assists self-taught learners in verifying whether their periphrastic sentences in Italian are well-turned. This area of Computer-Assisted Language Learning is currently poorly investigated. Further research might substantiate the importance of …

The Effectiveness of LDOCE Definitions for Concrete and Abstract Nouns in Headword- and Picture-Identification Tasks

2021

Abstract LDOCE uses a defining vocabulary to make their definitions intelligible to the user. Critics claim this policy may result in imprecise definitions, something especially noticeable in certain concrete and abstract words that are difficult to define by a definition only. This paper examines to what extent LDOCE definitions of such words help learners identify the objects and words being defined. In our experiment on 381 learners of English as a foreign language, three groups of participants viewed different definition types: simplified definitions of LDOCE, unsimplified definitions of MWC, and definitions written in the learners’ mother tongue (UDPL/TR). The results show that the LDO…

PROMOTING THE REGIONAL COMPETITIVENESS THROUGH CLUSTERS‘ APPROACH: CASE OF THE LATVIAN INFORMATION TECHNOLOGY CLUSTER

2018

The purpose of this research is to contribute to the debate on regional competitiveness concept by evaluating genesis of the studies of concept development, and the impact assessment. This paper also presents the impact of clusters on regional competitiveness through the experience of the Latvian Information Technology (IT) cluster. The methods used in the research are literature analysis, correlation and statistical analysis. The main tasks include: (i) the usage of competitiveness concept to describe main factors of regional competitiveness, (ii) identification of the role of clusters for regional competitiveness by testing the linkage between regional competitiveness and state of cluster…

Unsupervised clustering method for pattern recognition in IIF images

2017

Autoimmune diseases are a family of more than 80 chronic, and often disabling, illnesses that develop when underlying defects in the immune system lead the body to attack its own organs, tissues, and cells. Diagnosis of autoimmune pathologies is based on research and identification of antinuclear antibodies (ANA) through indirect immunofluorescence (IIF) method and is performed by analyzing patterns and fluorescence intensity. We propose here a method to automatically classify the centromere pattern based on the grouping of centromeres on the cells through a clustering K-means algorithm. The described method was tested on a public database (MIVIA). The results of the test showed an Accuracy…

EPA-0552 – Social rehabilitation and employment of people with intellectual disabilities

2014

Background Experience in the field of professional and social activation and employment of people with moderate and severe intellectual disabilities indicates the need to seek specific strategies for solving problems on the way into the labor market of people recruited from this social group. The analysis of the limitations and difficulties in recruiting these people, and based on samples taken before employing them on the open market, gave birth to the concept of developing an innovative system to support candidates for employment. Methods The development of the Project’Our work - preventing discrimination against disabled people in access to work, preceded by a very detailed analysis of t…

Experimental analysis of "bovedas tabicadas"

2012

A particular type of vaulted structures, known as bóvedas tabicadas (Catalan vaults), made with alternate layers of bricks and mortar and characterized by a very low thickness in comparison to the other two dimensions, are studied. The research has been faced under the historical aspect as well as under the mechanical one, developing experimental and numerical analysis regarding real existing structures. In particular, the experimental analysis, performed by effecting compression and bending tests on samples taken from a real structure, has been devoted to the constitutive material identification and the characterization is made by considering the material as an ideal homogeneous; further e…

New Tools for Streamlined In Vivo Homing Peptide Identification

2021

In vivo peptide-phage display is an unbiased technique for mapping of the vascular diversity and identification of homing peptides. This chapter is intended to serve as a structured practical guide to execute in vivo T7 phage biopanning and data analysis experiments. We discuss experimental designs and protocols with emphasis on application of high-throughput sequencing-based technologies for streamlined in vivo biopanning and validation of homing peptides.
