Recall that a model in the context of games with reachability objectives is a marked graph G = ((S,E), (S1, S2)), where S is the finite set of states, E the set of edges and S1 and S2 partition S. We abbreviate n = |S| and m = |E|. For any s in S, let E(s) = {s′ ∈ S | (s, s′) ∈ E} and assume that for all s in S, E(s) 6= ∅. T ⊆ S denotes the set of target states. Intuitively1 player 1 and player...

This Note proposes a novel radial-thrust combo metal mesh foil bearing (MMFB). Although MMFBs have advantages such as higher stiffness and damping over conventional air foil bearings, studies related to MMFBs have been limited to radial MMFBs. The novel combo MMFB is composed of a radial top foil, thrust top foils, and a ring-shaped metal mesh damper--fabricated by compressing a copper wire mes...

We discuss practical aspects of Kelvin probe force microscopy ~KFM! which are important to obtain stable images of the electric surface potential distribution at high spatial resolution ~,100 nm! and high potential sensitivity ~,1 mV! on conducting and nonconducting samples. We compare metal-coated and semiconducting tips with respect to their suitability for KFM. Components of the metal coatin...

Two extraction procedures for ecologically relevant elements present in automotive brake linings (Sb, Bi, Pb, Cd, Cr (total), Co, Cu, Mo, Ni, Sr, V, Zn, Sn) were developed and validated, applying a high pressure asher (HPA-S) and microwave extraction, respectively. Both of these methods allowed for the quantitative analysis of the extracted elements by inductively coupled plasma optical emissio...

Research into the use of eco-friendly materials, such as natural fibers, in brake pads has gained momentum last few decades. This can be attributed to potential fibers replace traditional materials tribological applications braking pads. The harmful impact commonly-used pad metal and mineral on human health environment necessitates development alternatives. Natural banana peels, palm kernels, s...

Abstract Miniaturized, microfabricated microelectromechanical systems-based wafer probes are used here to evaluate different contact pad metallization at low tip forces (<mN) and skate on the on-wafer pads. The target application is force RF for measurements which cause minimal damage both Low enables use of softer, more conductive metallisation. We have studied four thin film metals based t...

introduction: careful planning on health care may prevent the spread of disease and reduce the expense for treatment. regarding the importance of health care in the clinical centers including physiotherapy clinics, this study was designed to investigate the rate of bacterial contamination of electrotherapy’s pads which use in the physiotherapy clinics of semnan university of medical sciences (i...
