We use a Spectral Clustering model to formulate a distributed implementation using SPARK of Laplacian Eigenmaps that we call Distributed Spectral Dimensionality Reduction (DSDR). We evaluate DSDR to visualize conceptual clusters of terms in textual data from 2149 short documents written by online contributors to a State Department website. We compare DSDR with PCA, MultiDimensional Scaling, ISO...

PURPOSE. To compare the subjective outcome of acromioclavicular joint (ACJ) reconstruction using the modified Weaver-Dunn procedure versus the Surgilig synthetic ligament. METHODS. 55 patients aged 19 to 72 (mean, 42) years underwent ACJ reconstruction of Rockwood grade 3 (n=38), grade 4 (n=8), and grade 5 (n=9) using the modified Weaver-Dunn procedure (n=31) or the Surgilig synthetic ligament ...

Abstract With increasing digitization, new opportunities emerge concerning the availability and use of data in energy sector. A comprehensive literature review shows an abundance available unsupervised clustering algorithms as well internal, relative external cluster validation indices (cvi) to evaluate results. Yet, comparison different results on same dataset, executed with a specific practic...

OBJECTIVE To compare the existence of radiographic abnormalities in two groups of patients, those with and without hip pain. METHODS A total 222 patients were evaluated between March 2007 and April 2009; 122 complained of groin pain, and 100 had no symptoms. The individuals in both groups underwent radiographic examinations of the hip using the following views: anteroposterior, Lequesne false...

In this paper I show, with a rich and systematized diet of examples, that many contra-classical logics can be presented as variants FDE, obtained by modifying at least one the truth or falsity conditions some connective. Then argue using Dunn semantics provides clear understanding source contra-classicality, namely, connectives have either classical condition another This requires fine-grained ...
