The capability test of electronic tag
This paper introduces problems of electronic tag in actual application and the essentiality of capability test for electronic tag. We have established a test platform which is based on radio frequency and worked out some related schemes, which has laid the experimental foundations for further researching environmental influence factor in electronic tag in future.
On the read zone analysis of radio frequency identification systems with transponders oriented in arbitrary directions
One of the most important characteristics of a Radio Frequency IDentification (RFID) system is its "read zone", which is defined as the volume inside which the base station can communicate with the transponders (or, tags). This paper presents a systematic approach to analyzing the read zone of an RFID system where the base station antennas are a pair of switchable circularly polarized antennas and the transponder antennas are linearly-polarized and oriented in arbitrary directions.
Social Health Insurance Reforms—Mid-Term Experiences of Poland and Russia
As a result of transition process to market economy, Poland and Russia have come a long way from a centrally planned budget for social security to an insurance-type model in the social sphere. After more than two decades of reforms, it seems essential to compare and evaluate the policy solutions introduced in terms of the reform goals achieved and exposure to current challenges. The paper presents an analysis and comparison of social health insurance reforms conducted in Poland and Russia since the beginning of the 1990s. Moreover, the current problems of and future challenges for health care financing systems are identified. The varied experiences of Poland and Russia over more than 20 years show mid-term lessons which could be useful to other countries, especially those that face socio-economic transformation, in their choice of strategy and the practice of similar reforms.
