TL;DR: In this paper, a feedback-oscillator type active antenna using RF BJT with floating base terminal has been demonstrated for the first time, which has potential for future optical sensing and control circuitry, since the floating base is light sensitive.
Abstract: A feedback-oscillator type active antenna using RF BJT with floating base terminal has been demonstrated for the first time. Other than simplifying bias connections, which is important for large arrays and power combining, this has potential for future optical sensing and control circuitry, since the floating base is light-sensitive.

TL;DR: Radon transform (RT) is proposed to be used for feature extraction after obtaining the spectrogram from the speech sample and the performance of the proposed method has been compared for existing identification techniques in the field of language and speaker identification.
Abstract: Spoken language and speaker identification has been attracting the researchers across the globe for past several decades. Language identification shares certain similarities with speaker identification; however they both differ from each other in certain aspects. Both language identification and speaker identification problems have till now been dealt with feature extraction techniques like MFCC, PLP, LPCC etc. In this paper, a new feature extraction technique is proposed. Radon transform (RT) is proposed to be used for feature extraction after obtaining the spectrogram from the speech sample. PCA has been used to achieve dimension reduction and to reduce the computational complexity. The performance of the proposed method has been compared for existing identification techniques in the field of language and speaker identification.
