This paper unifies the analytical models used widely but thus far mostly separately for electrical and optical small amplitude perturbation measurements of nanostructured electrochemical dye solar cells (DSC): electrochemical impedance spectroscopy (EIS), intensity-modulated photocurrent spectroscopy (IMPS) and intensity-modulated photovoltage spectroscopy (IMVS). The models are linked by expre...

Many common tasks compromise arm stability along specific directions. Such tasks can be completed only if the impedance of the arm is sufficient to compensate for the destabilizing effects of the task. During movement, it has been demonstrated that the direction of maximal arm stiffness, the static component of impedance, can be preferentially increased to compensate for directionally unstable ...

An innovative method is presented to measure the mechanical driving point impedance of biological structures up to at least 40 kHz. The technique employs an atomic force cantilever with a ferromagnetic coating and an external magnetic field to apply a calibrated force to the cantilever. Measurement of the resulting cantilever velocity using a laser Doppler vibrometer yields the impedance. A key...

m ABSTRACT A method derived' for calculation of electromagnetic fields of a point charge moving along an axis of cylindrically symmetric structures is applied here to cavities and collimators with side tubes. The longitudinal impedance for such structures is calculated. In particular, the impedance for a pipe loaded with a thin washer is also calculated. It is shown that for large particle ener...

In a "classical" model of the cochlea the response is controlled by a local parameter function, for instance, the BM impedance. In a non-classical model, the response is controlled by parameters that are distributed over space. In this note it is shown to which extent classical and non-classical models are equivalent. To each non-classical model there exists one classical model that yields the ...

The black-box impedance model of voltage source inverters (VSIs) can be measured at their terminals without access to internal control details, which greatly facilitate the analysis inverter-grid interactions. However, VSI is dependent on its operating point and have different profiles when changed. This letter proposes a method for identifying under wide range points. approach based artificial...

Conventionally, human-robot communication and robot-robot communication are dealt with in different manners in general. From the viewpoint of cooperation between human staff and robots as a heterogeneous group, however, it is natural and desirable that all of the communication within the group is performed based on a uniform communication manner. In this study, we deal with a communication meth...
