Abstract Funding Acknowledgements Type of funding sources: None. Introduction Insufficient lesion depth and discontinuity lines are reasons for reconnections after point-by-point radiofrequent pulmonary vein isolation (PVI). Different technologies have shown to be useful prediction effective lesions. Measurement the magnitude local tissue impedance drop (LID) calculation size index (LSI) based ...

A low-to-medium cohesionless soil with low fines content was predominantly observed at the surfaces of Yogyakarta International Airport (YIA). The condition exposed subsoil YIA to Liquefaction in addition its location on a high seismic zone which has increased likelihood massive ground shaking. This means it is necessary improve and vibro-replacement using stone column selected as appropriate m...

BACKGROUND Musculoskeletal physiotherapists routinely assess lumbar segmental motion during the clinical examination of a patient with low back pain. The validity of manual assessment of segmental motion has not, however, been adequately investigated. METHODS In this prospective, multi-centre, pragmatic, diagnostic validity study, 138 consecutive patients with recurrent or chronic low back pa...

In this paper we present experiments for global polarity classification task of Spanish tweets for TASS 2015 challenge. In our methodology, tweets representation is focused on linguistic and polarity features such as lemmatized words, filter of content words, rules of negation, among others. In addition, different transformations are used (LDA, LSI, and TF-IDF) and combined with a SVM classifie...

In this research, a systematic study is conducted of four dimension reduction techniques for the text clustering problem, using five benchmark data sets. Of the four methods -Independent Component Analysis (ICA), Latent Semantic Indexing (LSI), Document Frequency (DF) and Random Projection (RP) -ICA and LSI are clearly superior when the k-means clustering algorithm is applied, irrespective of t...
