A novel non-contact vital-sign sensing algorithm for use in cases of multiple subjects is proposed.The approach uses a 24 GHz frequency-modulated continuous-wave Doppler radar 7gm pravana with the parametric spectral estimation method.Doppler processing and spectral estimation are concurrently implemented to detect vital signs from more than one su
Iradiasi gamma merupakan teknologi pengawetan pangan yang berpotensi untuk digunakan karena tidak menimbulkan perubahan sensoris seperti halnya pada pengawetan pangan konvensional (penggunaan panas).Teknologi ini mampu mereduksi bakteri patogen pada bahan pangan, seperti Escherichia coli, Staphylococcus aureus, Salmonella sp., Vibrio sp., dan Clost
In our previous paper, particle and temperature segregations in a fluidized bed of binary particle mixtures were experimentally examined, and heat transfer in the segregated fluidized read more bed was investigated.As the results, it was shown that the temperature segregation results mainly from low heat transfer coefficient through the interface l
