One of the exemplary domain is genomics – a new branch of science that developed rapidly in the last decade. As the genome research is very complex, it must be supported by professional informatics. In a microarray field the following steps cannot be performed without computational work: design of probes, quantitative analysis of hybridization results, post-processing, and finally data storage and management. Here, the general aspects of virtual laboratory systems are presented together with perspectives of their implementation in genomics in order to automate and facilitate this area of research

The Deployment of Remote Instrumentation Infrastructure (DORII) project aims at setting up an advanced Grid-based e-Infrastructure specifically oriented to the support of remote instrumentation devices on Grid extending the level of scientific instruments' exploitation. The paper highlights the main application areas and usage scenarios, key tasks of the Remote Instrumentation Infrastructure’s deployment and presents the joint research architecture for DORII in terms of advanced middleware solutions addressing the main tasks of identified applications

However, this paradigm does not only apply to large-scale laboratories and devices, but it can be fruitfully employed even with smaller and relatively widespread measurement instrumentation adopted in engineering applications. In this context, we consider the case of telecommunication measurements, and of their execution within the eInfrastructure, by using a subset of the service capabilities. We highlight some specific aspects of this environment, and we present an application example and some performance evaluation results

Material and Methods: Material consists of 50 pairs of intra-oral radiographs taken in 50 patients during normal oral clinical treatment. Two programs invented by the authors of this article: ToothVis 1.4 (TV) and DentalStudio 2.0 (DS) software were used in this study. Images obtained by two methods of DSR (cut and divide) and geometrically aligned with four methods were compared with the use of the peak signal to noise ratio (PSNR). Results: Analyzing the PSNR, it was observed that for cut subtraction its values ranged from 37.93 dB to 39.99 dB. For divide subtraction the PSNR values varied between 39.00 dB (03_pt_DS vs 10_pt_TV) and 47.73 dB (03_pt_TV vs 10_pt_TV). The PSNR achieved higher values for divide than for cut subtraction. Comparing cut and divide subtraction, the PSNR was the lowest for 3-point geometric alignment. Conclusion: Geometric alignment with the ToothVis software combined with divide subtraction gives the best quality of a subtracted image
