Anisotropy of some physical parameters in As-prepared As2S3 bulk glass

When cooling a melt the cooling rate in different layers varies due to differences in heat transfer. These changes in cooling rate were determined experimentally for the As₂S₃ melt in a quartz ampoule with diameter of 17 mm. The cooling rate at air quenching varies from 1.36 K/s in the bulk middle to 2.11 K/s in the border layers, and from 3.54 to 38.80 K/s for water quenching, respectively. Further, the corresponding changes in the density, microhardness, glass-transition temperature and electrical conductivity in dependence on the choice of the measured sample from various parts of the bulk were found. The anomalous behaviour of these parameters in dependence on the cooling rate corresponds to the polymeric structure of the glass.     

State estimation for real-time monitoring of distribution systems

Utilities currently use historical customer load data to forecast the loads in their distribution feeders for real-time feeder analysis and control. In this paper a three-phase state estimation method is developed to increase the accuracy of this load data. The method is based on the weighted least square approach and uses a three-phase node voltage formulation. The method can handle power, voltage, and current measurements. Test results indicate that state estimation can improve the forecasted load data by using real-time measurements. The effectiveness of branch current measurements were also tested     

Differential diagnosis of the transplant rejection and herpesvirus-related infections in kidney transplant recipients

An algorythm of differential diagnosis conduction of the transplant rejection reaction and the diseases caused by herpes viruses in recipients after the kidney transplantation was elaborated, basing on the analysis of results of the clinical, laboratory, immunological and serological examination methods.     

ESMO 2003

This paper illustrates the development of an interface for the simulator EMTDC/PSCAD for integrating an agent-based distributed application into the simulation. The custom device modules the EMTDC supports have been used to provide a channel for the agents to communicate (send and receive data) with the simulator. The main advantage of this interface is that the agents now can be developed independently, as separate JAVA applications. The application used to illustrate the features of the interface is a pilot protection scheme over a line.
