Most developers use default properties of ASP.NET server controls when developing web applications, which allows for rapid development of workable applications. However, creating a high-performance, multi-user, and scalable web application requires enhancement of server controls using custom-made code. In this empirical study we evaluate the impact of various technical approaches for paging and sorting functionality in data-driven ASP.NET web applications: automatic data paging and sorting in web server controls on web server; paging and sorting on database server; indexed and non-indexed database columns; clustered vs. non-clustered indices. We observed significant performance improvements when custom paging based on SQL stored procedure and clustered index is used.

TRANSMIT (Training Research and Applications Network to Support the Mitigation of Ionospheric Thr... more TRANSMIT (Training Research and Applications Network to Support the Mitigation of Ionospheric Threats) project is a Marie Curie Initial Training Network (ITN) funded by the European Commission. The final goal of the project is to develop integrated state of the art tools to mitigate ionospheric threats to Global Navigation Satellite Systems (GNSS) and several applications that rely on these systems. In particular, “Scientific and Industrial Applications Reliant on GNSS” is the TRANSMIT sub-project dedicated to the assessment of ionospheric effects on GNSS and related applications and aimed to develop countermeasures to mitigate them at receiver level. In this context, a processor has been designed and implemented with the purpose to process both GPS and GALILEO signals using different receiver tracking architectures/configurations and provide scintillation monitoring capabilities. The processor, described in this paper, includes three different tracking architectures, a traditional ...

Data from nearly 7000 energy meters at low–voltage consumers are processed, statistically reliable daily load curves are obtained and their characteristics are listed. Typical load duration curves of months belonging to winter and summer season are formed on the basis of daily load curves and depicted in the paper. These seasonal load duration curves of different load classes at low voltage are mutually compared. The influence of different number of working days, Saturdays and Sundays on monthly load duration curves is discussed, and corresponding load factors and loss factors for winter and summer months are statistically analysed.

Such emissions can be looked at under two aspects: the emissions might interfere with other equipment in the vicinity causing potential malfunction (EMC aspect), or might be considered with regard to human exposure (EMF aspect). Limitation of such emissions related to the EMC aspect

The impact of space weather events on satellitebased technologies (e.g. satellite navigation and ... more The impact of space weather events on satellitebased technologies (e.g. satellite navigation and precise positioning) is typically quantified on the basis of the total electron content (TEC) and temporal fluctuations associated with it. GNSS (global navigation satellite systems) TEC measurements are integrated over a long distance and thus may include contributions from different regions of the ionised atmosphere which may prevent the resolution of the mechanisms ultimately responsible for given observations. The purpose of the experiment presented here was to compare TEC estimates from EISCAT and GPS measurements. The EIS-CAT measurements were obtained along the same line of sight of a given GPS satellite observed from Tromsø. The present analyses focussed on the comparison of temporal fluctuations in the TEC between aligned GPS and EISCAT measurements. A reasonably good agreement was found between temporal fluctuations in TEC observed by EISCAT and those observed by a co-located GPS ionospheric monitor along the same line of sight, indicating a contribution from structures at E and F altitudes mainly to the total TEC in the presence of ionisation enhancements possibly caused by particle precipitation in the nighttime sector. The experiment suggests the great potential in the measurements to be performed by the future EISCAT 3D system, limited only in the localised geographic region to be covered.

When replacement takes place, one needs to migrate the data from the old database into the new database, so the new application can replace the old application. Student administration application (SAA) currently used by European University (EURM) has been outgrown by the university, and needs replacement. iKnow application developed as part of the iKnow Tempus project is scheduled to replace the existing Student Administration application at EURM. This paper describes the problems that were encountered while migrating the data from the old databases of SAA to the new database designed for the iKnow application. The problems were resolved using the well-known solutions typical for an ETL process, since data migration can be considered as a type of ETL process. In this paper we describe the solutions for the problems that we encountered while migrating the data.
