Steady-state fluorence imaging and time-resolved fluorescence imaging are two important areas in fluorescence imaging research. Fluorescence lifetime imaging is an absolute measurement method which is independent of excitation laser intensity, fluorophore concentration, and photobleaching compared to fluorescence intensity imaging techniques. Time-gated fluorescence lifetime imaging microscopy ...

Accurate density functional calculations are performed to investigate the structure and vibrational dynamics of carbon monoxide adsorbed to the (100) surface of copper. The adsorbate and substrate are considered as a unified system, with atoms of each treated on an equal footing. Coupling between the two components is found to have a significant effect. In particular, frustrated translational m...

This paper presents an analysis technique that can be used to compute the harmonic and intermodulation distortion levels of a sampled-data circuit directly from a SPICE transient analysis. It is useful for analyzing the non-linear behavior of switched-capacitor and switched-current circuits at the transistor level. The approach is valid for all input signal levels, makes no assumption of the un...

Due to the lower tool as the research object to analyze the vibration of the drill string, causes the loss of the low order natural frequency of the drill string and the inherent vibration mode, give rise to the distortion and error of the result from the transient analysis of the drill string. For this purpose, the whole drill string of the deep wells is studied in the article, build the mecha...

Linguistics: towards metatheorising organisational discourse Nur in einer Sprache can ich etwas mit etwas meinen. (It is only in a language that I can mean something by something.) Wittgenstein, L. Philosophical Investigations 1.0 Introduction Over the past two decades or so, changes in society, the sciences and technology have induced a significant shift in knowledge production, not only in th...

This paper presents a particle swarm optimization (PSO)-based neuro-sliding mode controller for the transient stability enhancement of multimachine power systems with unified power flow controller (UPFC). The UPFC is modeled as controllable loads. These controllable parameters are obtained using the sliding mode control (SMC) strategy. A PSO-based single neuron controller is used to adapt the p...

This paper presents a time-varying sliding mode adaptive controller in order to handle the stick-slip oscillation of nonlinear rotary drilling system. The time-varying sliding mode controller with strong robust has two time-varying sliding surfaces, one of them induced time-varying integral sliding mode control can control the transient stage of the rotary drilling system and ensure the system ...

A number of authors have recently proposed a future for science where the traditional academic mode of knowledge production, primarily organised on disciplinary lines, is largely replaced by a different mode of knowledge production that is more transient in its organisational forms. If correct, the new mode of knowledge production has implications for the research cultures of universities, gove...

An adaptive reconfigurable flight control system using the mode switching of multiple models is studied. The conventional mode switching method may not guarantee the stability and the performance of the system. In this study, modified adaptive mode switching and decision logic are proposed to improve the adaptiveness of the transient dynamics of a system while maintaining the stability of the c...
