A surface-micromachined capacitive-type micro electro-mechanical system (MEMS) acoustic sensor with 0.8 μm CMOS impedance transducer is presented. This sensor chip is composed of a surface-micromachined MEMS microphone with X-shape bottom electrode anchors and a simple monolithic integrated impedance transducer based on 0.8 μm CMOS process (1 poly-2 metals), where Metal 2 in...
This paper mainly focuses on the research of the time-delay impact on electrical response of the proton exchange membrane fuel cell (PEMFC) system. Firstly, original static stack voltage and pressure models are proposed. Then, time-delay is discussed and analyzed. Thirdly, a time-delay mathematical model based on previous analysis is proposed and combined with the original model of PEMFC. After that,...
This paper presents a dynamic multi-input multi-output (MIMO) model of PEM fuel cells and a nonlinear control approach appropriate for this model based on exact linearization. Since large deviations of pressures between anode and cathode gases can cause severe membrane damage in fuel cells, it is necessary to design a corresponding controller so that the deviation can be kept as small as possible...
ErbB overexpression is linked to carcinogenesis. It is hypothesised that this is due to increased receptor density and receptor clustering, leading to increased receptor dimerisation and activation. Herein, spatial stochastic simulations have been performed to shed light receptor dimerisation processes. First, ligand- independent homodimerisation, is considered, based upon constitutive oligomerisation...
