The Piraeus AIS dataset for large-scale maritime data analytics.

The advent of Big Data and streaming technologies has resulted in a swarm of voluminous, heterogeneous information, especially in the domains of Internet of Things (IoT) and transportation. Focusing on the maritime field, in this paper, we present a dataset that contains vessel position information transmitted by vessels of different types and collected via the Automatic Identification System (AIS). The AIS dataset comes along with spatially and temporally correlated data about the vessels and the area of interest, including weather information.

A pattern similarity scheme for medical image retrieval.

In this paper, we propose a novel scheme for efficient content-based medical image retrieval, formalized according to the PAtterns for Next generation DAtabase systems (PANDA) framework for pattern representation and management. The proposed scheme involves block-based low-level feature extraction from images followed by the clustering of the feature space to form higher-level, semantically meaningful patterns. The clustering of the feature space is realized by an expectation-maximization algorithm that uses an iterative approach to automatically determine the number of clusters.

A seroepidemiological study of toxoplasma gondii infection in children of northern Greece.

The aims of this study were to determine the incidence of toxoplasmosis in children ofthe northern Greece region through the evaluation of serologic examination. Sera of 486 children, aged between 6 months and 15 years, suffering from different clinical entities, were tested for anti-Toxoplasma gondii specific IgG antibodies, using an ELISA (enzyme linked immunosorbent assay) technique. In this survey, a high percentage (11.

Leishmania antibodies in children’s serum samples in correlation with the disease in dogs.

Sera of 489 children from Northern Greece aged between 6 months and 15 years of age and aflicted with different clinical entities, were tested for anti – Leishmania infantum specific IgG and IgM antibodies, using an ELISA (enzyme linked immunosorbent assay) technique. In this survey, a remarkably high percentage (8.5%) of hospitalized children reacted positively to this method.
