A new voting procedure for electing committees, called the minimax procedure, is described. Based on approval voting (AV), it chooses the committee that minimizes the maximum “Hamming distance” to all voters (minimax outcome). Such an outcome may be diametrically opposed to the outcome obtained from aggregating votes in the usual manner, which minimizes the sum of the Hamming distances to all v...

The effect of rare earth (RE) elements, including Ce and La, on the sorption properties of Zr-Co getters was investigated in this work. The phase evolution, microstructural characteristics of getter powders were studied by means of X-ray diffraction method, scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS). The nanostructured Zr3Co intermetallic compound has been...

Metallic coatings on the inner surfaces of vacuum chambers are widely used in accelerators but impact coating resistivity beam coupling impedance and dynamics is often not sufficiently evaluated. In this paper, it shown that, for usual thickness, electrical can have a strong microwave instability threshold. particular, using different nonevaporable getters as examples, regime which with lower p...

Collaborative robots are increasingly present in our lives. The KUKA LBR iiwa equipped with the KUKA Sunrise.OS controller is a good example of a collaborative/sensitive robot. This paper presents a MATLAB Toolbox, the KUKA Sunrise Toolbox (KST), to interface KUKA Sunrise.OS using MATLAB. The KST contains functionalities for networking, real-time control, point-to-point motion, setters and gett...

Plastic encapsulated microcircuits with aluminum triple track structures were exposed to mixed flowing gas conditions to simulate and accelerate possible environments during long-term storage. No increase in resistance was measured and no corrosion products were observed after 800 h of accelerated exposure. Further experimentation indicated that chloride gas reacts with surface moisture in micr...

In many accelerator storage rings running positively charged beams, multipactoring due to secondary electron emission (SEE) in the beam pipe will give rise to an electron cloud which can cause beam blow-up or loss of the circulating beam. A preventative measure that suppresses electron cloud formation is to ensure that the vacuum wall has a low secondary emission yield (SEY). The SEY of thin fi...
