1Measurement of Plasma Parameters of Calcium and Silicon in a Rock Sample Using Laser Induced Breakdown Spectroscopy显示文摘Laser Induced Breakdown Spectroscopic(LIBS)technique was used to detect calcium and silicon in an unknown sample.In this method plasma was generated by Nd∶YAG laser of wavelength 1 064 nm with energy 400 mJ and pulse duration between 5~10ns.The method was applied for the qualitative as well as quantitative analysis.In the qualitative analysis,the electron number density(Ne)of plasma containing calcium and silicon is determined showing that Neof neutral particles is equivalent to 1016(cm-3)whereas for ionized particles it is 1017(cm-3).Plasma temperature is measured using Boltzmann plot method which must be greater than 10 000 k.Intensity ratio method is used for the quantitative analysis shows various elements in abundance with calcium and silicon in majority.Uzma G M.Junaid Khalid Alamgir T Samina 2017光谱学与光谱分析2017,37,10:4
2On Almost Controllability of Dynamical Complex Networks with Noises显示文摘This paper discusses the controllability problem of complex networks.It is shown that almost any weighted complex network with noise on the strength of communication links is controllable in the sense of Kalman controllability.The concept of almost controllability is elaborated by both theoretical discussions and experimental verifications.CAI Ning HE Ming WU Qiuxuan KHAN M.Junaid 2019Journal of Systems Science & Complexity2019,32,4:2
3A Modified Non-Uniform DMT Transceiver for the Digital Subscriber Line显示文摘A Non-Uniform Discrete-Multitone(DMT) transceiver can help mitigate the channel-noise enhancement,attributed to zero-forcing equalization (ZFE) technique,by splitting the channel frequency response into octave spaced subbands.This paper presents a novel quantitative analys is of the channel-noise enhancement in different subbands of the Non-Uniform DMT system.In order to improve the bit error rate(BER) performance,a modified Non-Uniform DMT transceiver is proposed.The BER performance of the modified Non-Uniform DMT system is compared with that of the Non-Uniform DMT and conventional DMT systems in a Digital Subscriber Line(DSL).Sobia Baig M.Junaid Mughal 2007China Communications2007,4,4:0
