Automatic adjustment of chopping-modulated defibrillation pulses to patient transthoracic resistance

A 60kV/6kW full-digital high voltage power supply for electronic beam welder (EBW) is designed. The power is composed of DSP, CPLD, IPM etc. It has realized the automatic adjustment of high voltage, over-voltage and over-current protection, and rapid recovery from high voltage self-discharge. The test proves that high voltage power supply has reached design goal and satisfied the actual requirements of welding technology.

Final Alignment

Ontology matching plays an important role in the integration of heterogeneous data sources that are described by ontologies. In order to determine correspondences between ontologies, a set of matchers can be used. After the execution of these matchers and the aggregation of the results obtained by these matchers, a final alignment method is executed in order to select appropriate correspondences between entities of compared ontologies. The final alignment method is an important part of the ontology matching process because it directly determines the output result of this process. In this paper we improve our iterative final alignment method by introducing an automatic adjustment of final alignment threshold as well as a new rule for determining false correspondences with similarity values greater than adjusted threshold. An evaluation of the method is performed on the test ontologies of the OAEI evaluation contest and a comparison with other final alignment methods is given.

Reserve Ratio

The specific design of the Bulgarian currency board arrangement (CBA), which provides an opportunity for the Bulgarian government to conduct discretionary monetary policy by changes in the fiscal reserve, was analyzed. The impact of government deposit fluctuations on the dynamics of reserve money and interbank interest rates was investigated. The hypotheses of an automatic adjustment mechanism and a liquidity effect under the Bulgarian currency board arrangement were tested. The methodology employed was a vector autoregression, which included the following variables: MB – monetary base; BP – the balance of payments; GD – government deposit on the balance sheet of the Issue Department of the Bulgarian National Bank; MRR – minimum required reserve ratio of commercial banks. The target variable was MB. Monthly data for the period of January 1998 - December 2018 were used. The study results did not provide evidence of a statistically significant impact of changes in government deposit on reserve money and interbank interest rates. The hypotheses for the existence of an automatic adjustment mechanism and a liquidity effect did not find an empirical confirmation.
