Semantic incompatibility is a conflict that occurs in the meanings of data. In this paper, we propose an approach for data cleaning by resolving semantic incompatibility. Our approach applies a dynamic and incremental enhancement of data quality. It

Trajectories of people contain a vast amount of information on users' interests and popularity of locations. To obtain this information, the places visited by the owner of the device on such a trajectory need to be recognized. However, the location i

Suppression of 18F-FDG Myocardial Uptake Using a Fat-Allowed, Carbohydrate-Restricted Diet

Autor: Thomas Pol, Freerk-Jan Flokstra, Mark Roef, Hans Balink, Evelien Hut

Publikováno v: Journal of nuclear medicine technology. 39(3)

Patients prepared by the generally used fasting protocol show variable myocardial (18)F-FDG uptake, which may result in difficult interpretation of mediastinal (18)F-FDG uptake. This retrospective study described the effect of a 1-d fat-allowed, carb

Publikováno v: IEEE transactions on knowledge and data engineering, 4(6), 541-554. IEEE Computer Society

PRISMA/DB, a full-fledged parallel, main memory relational database management system (DBMS) is described. PRISMA/DB's high performance is obtained by the use of parallelism for query processing and main memory storage of the entire database. A flexi

A wideband 100 kHz-4 GHz power sensor, of which the basic design was presented recently by L. J. Fernandez et al. (2004), was successfully realized. The sensor is based on sensing the electrical force between the RF signal line and a suspended membra

We present the first measurement results of a power sensor for radio frequency (rf) signals (50 kHz - 40 GHz) with almost no dissipation during the measurement. This sensor is, therefore, a 'through' power sensor, that means that the rf signal is ava
