The APD statistical analysis of the high-speed system electromagnetic noise
This paper mainly discusses the power network offline noise of high-speed railway system, and uses the MATLAB simulation analysis on its amplitude probability distribution. The results show that the characteristics of the noise mentioned in this article is consist with the theoretical model of the high-speed railway system. It can be used to study the effects of such noise on the high-speed system.
On the Relation Between the Amplitude Probability Distribution of Noise and Bit Error Probability
In the paper entitled "Relation Between the Amplitude Probability Distribution of an Interfering Signal and Its Impact on Digital Radio Receivers," a formula for estimating the bit error probability of an interfered digital wireless receiver was presented in terms of the amplitude probability distribution of the noise. This formula is very useful for predicting the impact of interfering signals on digital wireless systems and for defining appropriate limits for the interfering signal level to protect wireless systems. However, the formula must be corrected so that it is valid for modulation schemes, such as quadratic-amplitude modulation and multiple phase-shift keying.
The politics of becoming bodies: Sex, gender and intersubjectivity in motion
Abstract This paper presents readers with one (research) story about (sexed and gendered) bodies not as objects with inherent boundaries and properties but as material-discursive phenomena. In telling such a story I examine the role that the screendance, Becoming Bodies , has played in knowledge production and argue for a less ontologically ‘old fashioned’ view of what counts as ‘evidence’. Throughout the paper I draw from a range of feminisms: biological, phenomenological, poststructural, psychoanalytical, and post humanist and performative scholarship of sex and gender. These discourses contest nature/nurture, male/female, body/mind dualisms, and take the political and ethical view that bodies are not neutral; that sex and gender, being a woman or a man are both socially and biologically constructed forms of identity (similar to class and race) that are acquired and learned through socio-cultural regimes of discipline and intersubjective bodily practices. Building on this dynamic and developmental bio-psycho-social view I discuss selected aspects of interview data: (1) the material-discursive tensions and contradictions of sexing and gendering bodies and (2) troubling the intersubjective implications of this for clinical practices.
