A&met-Wang alebra is defined by three rules: i) go =yx; ii) x + x = 0; and iii) xx =O. K. T. Wang showed that these rules give a shortcut method for finding tbe joint resistance (or driving point reshance) of an electrical network. However, there are electrical systems more general than the KIrckhoff network. For these system regular matroids repiace‘ networks. It is shown in this paper that Wa...

After being affected by naturally low temperature (-4~0°C), the changes of relative electrical conductivity and MDA content of 11 fennel varieties were tested. The experiment studied the relationship between the cold resistance and changes of relative electrical conductivity and MDA content of varieties. The results showed that the relative electrical conductivity and MDA content were higher th...

The ability to fine-tune feature size in nanostructured thin films is critical, as many desirable properties of these materials are dictated by their nanostructure. Accordingly, there is a need for techniques that allow for modifying nanostructure while monitoring the morphological changes in situ. Here, we demonstrate a closed-loop electro-annealing system which enables in situ monitoring of m...

The efficacy of laser annealing for the thermal annealing of nanocrystalline gold nanowires is evaluated. Continuous laser illumination at 532 nm, focused to a 0.5 μm diameter spot, was rastered perpendicular to the axis of nanocrystalline gold nanowire at ∼2 kHz. This rastered beam was then scanned down the nanowire at velocities from 7 to 112 nm/s. The influence on the electrical resistance o...

Using an atomic force microscope (AFM) at a controlled contact force, we report the electrical signal response of multi-walled carbon nanotubes (MWCNTs) disposed on a golden thin film. In this investigation, we highlight first the theoretical calculation of the contact resistance between two types of conductive tips (metal-coated and doped diamond-coated), individual MWCNTs and golden substrate...

Circuit Breakers (CBs) are critical components in power system for reliability and protection. To assure their accurate performance, a comprehensive condition assessment is of an imminent importance. Based on dynamic resistance measurement (DRM), this paper discusses a simple yet effective fuzzy approach for evaluating CB’s electrical contacts condition. According to 300 test results obta...

anxiety disorders are the most common reasons for referring to specialized clinics. if the response to stress changed, anxiety can be greatly controlled. the most obvious effect of stress occurs on circulatory system especially through sweating. the electrical conductivity of skin or in other words galvanic skin response (gsr) which is dependent on stress level is used; beside this parameter pe...

Electrical circuit analysis was used to study the structural development of occluding junctions (OJs) in cultured monolayers composed to T84 cells. The magnitude of the increments in transepithelial resistance predicted by such analysis was compared with the magnitude of the measured increments in resistance. Confluent sheets of epithelial cells were formed after cells were plated at high densi...

During the process of death the electrical conductivity of many tissues undergoes a change in electrical resistance by means of which the process may be followed with considerable precision. This may be utilized to measure injury and recovery. 1 An illustration of this is seen in Fig. 1, which shows the gradual fall in resistance 2 of Lamlnaria placed in 0.52 ~t NaC1. 8 After an exposure of 5.2...
