In epidemiological studies there exists the evidence of relationship between socio-economic status (SES) and health. The suspicious cause of these differences is life-style. The aim of the presented study was to identify the relationship between SES, demographic characteristics and the life-style in an industrial region. A structured questionnaire was distributed to a random sample of some 3,00...

In this paper, a novel method of relevance feedback is presented based on Support Vector Machine learning in the content-based image retrieval system. A SVM classifier can be learned from training data of relevance images and irrelevance images marked by users. Using the classifier, the system can retrieve more images relevant to the query in the database efficiently. Experiments were carried o...

In recent years multimedia researchers have attempted to design content-based image retrieval systems. However, despite the development of these systems, the term "content" has still remained rather ill defined, and this has made the evaluation of such systems problematic. This paper proposes a method for the creation of a test set of images in which the similarity of each image pair is estimat...

Automated detection of anomalous events plays an important role in video surveillance systems in practice. This task, however, requires to deal with three challenging problems of the lack of annotated training data, the inexact description of what to be “abnormal” and the expensive feature engineering procedure. Most anomaly detection systems are only able to satisfy some of these challenges. I...

This paper presents a mesh adaptation method for higher-order (p > 1) discontinuous Galerkin (DG) discretizations of the two-dimensional, compressible Navier–Stokes equations. A key feature of this method is a cut-cell meshing technique, in which the triangles are not required to conform to the boundary. This approach permits anisotropic adaptation without the difficulty of constructing meshes ...

The effects of thermally accelerated ageing in irradiated and unirradiated 1310nm InGaAsP edge-emitting lasers and InGaAs p-i-n photodiodes are presented. 40 lasers (20 irradiated) and 30 photodiodes (19 irradiated) were aged for 4000 hours at 80°C. Periodic measurements were made of laser threshold and efficiency, and pi-n leakage current and photocurrent. There were no sudden failures and the...

In this paper we present a novel approach to shape similarity estimation based on ordinal correlation. The proposed method operates in three steps: object alignment, contour to multilevel image transformation and similarity evaluation. This approach is suitable for use in CBIR. The proposed technique produced encouraging results when applied on the MPEG-7 test data.

We report on the automatic testing of the control software of the Oosterschelde kering, a storm surge barrier. The automatic testing includes automatic test case derivation and automatic test execution. This project is a joint effort of CMG and the computer science group “Formal Methods and Tools” at the university of Twente. We introduce the way we currently test at the Formal Methods and Tool...

We identified that virtual worlds that rely on user generated content often lack accurate metadata for their objects. The apparent lack of metadata is a problem for users who are visually impaired, as they rely upon textual descriptions of objects to be present for accessing virtual worlds using assistive technology, such as a screen reader or tactile display. This paper presents a scavenger-hu...

Subjective memory ratings provide information that is distinct from objective memory performance, and there is a need for reliable and valid metamemory measures. The Multifactorial Memory Questionnaire (MMQ), developed to assess separate dimensions of memory ratings that are applicable to clinical assessment and intervention, includes scales of Contentment (i.e., affect regarding one's memory),...
