This paper gives a survey of the deployment of ideas from the area of real-time, active and heterogeneous database systems in the years from 1991 to 2010 as they have been embraced by IT industry. During that time the Database and Distributed Systems group (DVS) led by Alejandro Buchmann has made lots of contributions to the development of those ideas by many research projects. After 20 years i...

Several caching schemes for realtime multimedia systems have been proposed but they have only concentrated on the hit ratio as a performance metric without providing any means to utilize the disk bandwidth gained through cache hits. A high cache hit ratio alone does not capture the eeectiveness of a caching scheme for such systems unless hiccup-free service is guaranteed. We evaluate four cachi...

The main goal of this paper is to provide an overview of a variety of methods for synthesis of eroded terrain for use in computer games, VR worlds and the like. Traditionally, such software uses either predefined terrains or runtime generated data based on simple fractal noise techniques. In recent years, the advances in processing power of average home computers have made it possible to simula...

INTRODUCTION Human papillomavirus (HPV) testing has become an essential part of current clinical practice in the management of cervical cancer and precancerous lesions. We reviewed the most important validation studies of a next-generation real-time polymerase chain reaction-based assay, the RealTime High Risk HPV test (RealTime)(Abbott Molecular, Des Plaines, IL, USA), for triage in referral p...

BACKGROUND Pneumococcal serotyping is usually performed by Quellung reaction, considered the gold standard test. However the method cannot be used on culture-negative samples. Molecular methods can be a useful alternative. The aim of the study was to evaluate the use of Multiplex-sequential-PCR (MS-PCR) or Realtime-PCR on blood samples for diagnosis and serotyping of invasive pneumococcal disea...
