In this work, we propose a highly efficient binary tree‐based anti‐collision algorithm for radio frequency identification (RFID) tag identification. The proposed binary splitting modified dynamic tree (BS‐MDT) algorithm employs a binary splitting tree to achieve accurate tag estimation and a modified dynamic tree algorithm for rapid tag identification. We mathematically evaluate the performance of the BS‐MDT algorithm in terms of the system efficiency and the time system efficiency based on the ISO/IEC 18000‐6 Type B standard. The derived mathematical model is validated using computer simulations. Numerical results show that the proposed BS‐MDT algorithm can provide the system efficiency of 46% and time system efficiency of 74%, outperforming all other well‐performed algorithms. 相似文献

Semi-refined carrageenan (SRC) production from decolourised Kappaphycuz alvarezii treated by chemicals (CaCO3) drives the search for ‘greener’ decolourisation methods to sustainably supply cheaper and energy efficient products. Therefore, a decolourisation method of low-salinity seawater (LSS) (3, 9 and 15 g/L) was investigated to replace CaCO3. In addition, decolourised seaweed colour powder (DSP) and SRC colour, yield, viscosity and gel strength were used to screen the salinity treatments. SRC prepared from LSS (3 g/L) treatment demonstrated similar colour and physical properties to CaCO3 treatments, which indicated low-salinity seawater (3 g/L) could replace CaCO3 as a decolourising agent. Moreover, purity of SRC (3 g/L salinity) were confirmed by x-ray diffraction (XRD), scanning electron microscopy-energy-dispersive x-ray (SEM-EDX), and its functional group by fourier transform infrared (FTIR). In this study, waste seawater from LSS (3 g/L) exhibited radical scavenging properties. This decolourising method could be easily adopted by smallholder seaweed farmers in low- and middle-income countries. 相似文献
