Contours of pacificism: Ramsden Balmforth's advocacy of peace in the Union of South Africa and beyond by F. Hale

“… Among the many dimensions of Christian pacifism in South Africa which remain underexplored is the ministry of the Unitarian minister Ramsden Balmforth (1861-1941). For approximately four decades beginning shortly after his arrival in Cape Town in 1897, this Christian socialist devoted part of his time to efforts to promote peace both in southern Africa and on a broader, almost global, scale. …”

RELIABILITY ANALYSIS OF MECHANISM OVER-CENTER LOCKING CONSIDERING WEAR AND CLEARANCE by QIN Qiang, LI TingTing, FENG YunWen, XUE XiaoFeng

“…Depending on the form of mechanism,the hinge wear and rod end bearing wear are considered respectively,and the self-lubricating rod end bearing wear model are established.Then the over-center locking reliability analysis model of four bar linkage mechanism is built under the "effective lever length theory"and "continuous contact model"hypothesis,besides,a reliability analysis method of over-center locking considering the initial clearance and wear is presented.The results show that the failure probability of mechanism over-center locking will rapidly increase after a certain number of cycles; the reliability of mechanism over-center locking will be significantly improved by using self-lubricating rod end spherical plain bearing.…”

I manoscritti etiopici della Biblioteca Statale di Montevergine a Mercogliano, Avellino by Alessandro Bausi

“…The manuscripts date to the nineteenth (non post 1895 CE, Cod. 24, Praise of Mary and Gate of Light) and to the beginning of the twentieth century (1907/1908 CE, Ms. 3, Image of the Twenty-Four Heavenly Priests and Ethiopian Psalter). The first manuscript was apparently taken from the field tent of Rās Mangašā after the Battle of Saganayti, on 15 January 1895, and eventually donated on 27 November 1900 by Daǧāzmāč Mikāʾel to the Italian colonial officer Ilario Capomazza. …”

New SNR estimation algorithm based on relevance vector machine by Bo HAN, Jie WU, Hua XU, Hai-ou SHEN, Peng LI

“…A new SNR estimation algorithm based on relevance vector machine (RVM) was proposed,it can not only be used under the flat fading channel,but also meet the request of larger estimation range and higher estimation accuracy of PSK.The estimation model was created by using RVM,based on the relation between the SNR and the two-order moments and four-order moments,and the reliable weights of the model can be figured out by straining and studying.Simulation results show that this algorithm has lots of advantages,for example,it uses less data and has larger estimation range than general algorithm,in addition,its estimation accuracy becomes higher in the effective estimation rang,and it is applicable to more modulation signals.…”
