In this paper,a low-pressure capacitively coupled plasma discharge sustained in an argonoxygen mixture was studied in order to evaluate its properties in terms of inactivation of Staphylococcus *** plasma parameters as electron temperature and plasma density were measured by the Langmuir probe(Ne≈1015 m^-3,Te≈1.5 eV),while the neutral atom density was in the range of 1021 m^-*** the plasma phase,oxygen radicals were taken as reference of the reactive species with antimicrobial activity,and oxygen spectral lines,over a range of plasma process parameters,were investigated by the optical emission *** plasma conditions were found,and a count reduction of 4 log in a few minutes of the bacterium proves the potentiality of an industrial grade plasma reactor as a sterilization agent.

Enabling Flexible Packet Filtering Through Dynamic Code Gene...

2008 IEEE International Conference on Communications(ICC 2008)

作者： O.morandi F.Risso m.Baldi A.Baldini Dipartimento di Automatica e Informatica Politecnico di Torino Torino Italy Cisco Systems San Jose CAUSA

Despite its efficiency, the general approach of hardcoding protocol format descriptions in packet processing applications suffers from many limitations. Among the others, the lack of flexibility when needing to extend the software for supporting new protocols, and the proliferation of modules with similar functionality between different applications, resulting in decreased maintainability. The NetPDL language was defined for overcoming such limitations, allowing decoupling applications from the knowledge of the format of protocol headers. The main criticism to NetPDL relates to its supposed performance penalties;this paper demonstrates that this language can be effectively used for the dynamic generation of optimized, i.e. efficient and fast, packet-processing code, and presents the architecture of a compiler implemented for such purpose.

多年前,笔者在罗马的Via del Babuino街上散步,这条街在当时是古董街。笔者带着好奇心偶然在Valdese教堂旁边发现了Querzola古董书店橱窗里的一幅版画。一张小卡片上写着这幅画的创作者是一位名叫乔治·莫兰迪(Giorgio morandi)的艺术家,当时笔者对这个名字还很陌生。那是一幅静物版画,画中的各个物体都通过黑白色调和半色调的平面产生模糊而强烈的对比。
