We are developing a far field gain and an antenna factor estimation method for EMI broadband antennas using the amplitude center distance and time frequency analysis technique. Our method is using an amplitude center modified Friis transmission formula. In this paper, we show the measurement results of far field antenna factor of log-periodic dipole array antenna on an open area test site. In the...
A purpose of this research is to improve a user's balance of income and expenditure by forecasting and presenting future consumption from past purchase information. First, we recorded various purchase information by scanning a large number of receipts and applying them to OCR (Optical Character Recognition). We named this system “Receiptlog”. From data of Receiptlog, we found out cycles of time and...
