Abstract

The maximum read range of a Radio Frequency Identification (RFID) system depends on a number of factors. In this paper, the maximum read ranges of an RFID system with a handheld RFID reader and another RFID system with a fixed RFID reader were tested when a tag was attached to different materials. Distinguishing factors that influence the maximum read range is important. A design of experiments (DOE) method was used to understand and quantify the relative influence of three factors (the antenna number, the tagged material, and the RF interference) on the maximum read range of the RFID system with a fixed RFID reader. The influences of the three factors and their interaction effects were classified by an order of importance. The methods in this paper also apply to the study of other RFID systems and determining the relative influences of other selected factors or parameters as well as other materials.DOI:http://dx.doi.org/10.11591/ijece.v4i1.5103

Abstract

The purpose of this study was to investigate the iris image quality and iris verification of eyes in brown, hazel, green, and blue, respectively, and the iris image quality and iris verification under different conditions such as the changed stand-off distances, the motions of the head and eyes, with glasses, and without glasses. A comparative study of three eye colors in brown, hazel, and green was conducted using a non-parametric method based on the H test. The H test results show that there is no significant difference in the iris image quality of eyes in brown, hazel, or green when the level of significance is 0.05.DOI:http://dx.doi.org/10.11591/ijece.v3i4.2769

Abstract

The purpose of this paper is to investigate fingerprint quality and quality problems due to nonlinear elastic distortion. The effect of force on fingerprint quality was studied using computation and analysis of the correlation coefficient r between the fingerprint quality score and force. The correlation analysis results show that fingerprint quality is significantly attributed to force. Based on the U test, a comparative study between male and female students about the fingerprint quality was conducted. At the 0.05 level of significance, there is a significant difference between male and female students in the fingerprint quality of the flat left thumb at a greater force level and in the fingerprint quality of the slap left fingers at all force levels.DOI:http://dx.doi.org/10.11591/ijece.v3i3.2489
