Polarization Capacity

In this paper, we address one of the most important topics in the field of Social Networks Analysis: the community detection problem with additional information. That additional information is modeled by a fuzzy measure that represents the risk of polarization. Particularly, we are interested in dealing with the problem of taking into account the polarization of nodes in the community detection problem. Adding this type of information to the community detection problem makes it more realistic, as a community is more likely to be defined if the corresponding elements are willing to maintain a peaceful dialogue. The polarization capacity is modeled by a fuzzy measure based on the JDJpol measure of polarization related to two poles. We also present an efficient algorithm for finding groups whose elements are no polarized. Hereafter, we work in a real case. It is a network obtained from Twitter, concerning the political position against the Spanish government taken by several influential users. We analyze how the partitions obtained change when some additional information related to how polarized that society is, is added to the problem.

Measurements have been made of the capacitance and conductance at 200 c.p.s. of a series of potassium bromide crystals doped with divalent anion and cation impurities. The dependence of the space-charge polarization capacity, caused by blocking of current carriers at the electrodes, on the conductivity and diffusion coefficient of carriers has been established. It is concluded that linearized theories of space-charge polarization cannot explain the experimental results.

1. The specific capacity of a suspension is that capacity which) combined in parallel with a certain resistance, electrically balances 1 cm. cube of the suspension. 2. The following formula holds for the specific capacity of a suspension of spheroids, each of which is composed of a well conducting interior surrounded by a thin membrane of a comparatively high resistance: See PDF for Equation C, specific capacity of suspension; Co, static capacity of one sq. cm. of membrane; r, r1 specific resistances respectively of suspension and of suspending liquid; 2 q major axis of spheroid, α constant tabulated in Table I. 3. The following formula holds practically for any suspension whatever the form of the suspended particle. See PDF for Equation C = C100 being the specific capacity of a suspension with a concentration of 100 per cent. Formulæ (1a) and (1b) hold only for the case, when the frequency is so low, that the impedance of the static capacity of the membrane around a single particle is high as compared with the resistance of the interior of the particle. The formulae hold also for a suspension of homogeneous particles, when polarization takes place at the surface of each particle, provided the polarization resistance is low as compared with the impedance of the polarization capacity. 4. A description is given of a method for measuring the capacity of a suspension at frequencies between 800 and 4½ million cycles. By means of a specially designed bridge, a substitution method is employed, by which in the last analysis the suspension is compared with the suspending liquid which is so diluted as to have the same specific resistance as the suspension, consecutive measurements being made in the same electrolytic cell. 5. Formula (1b) is verified by measurements of the capacity of suspensions of varying volume concentrations of the red corpuscles of a dog. 6. By means of the above measurements, the value of Co is calculated by equation (1a). 7. It is found that Co is independent of the frequency up to 4½ million cycles and that it is also independent of the suspending liquid. These results furnish considerable evidence of the validity of the theory, that Co represents the static capacity of a corpuscle membrane. 8. On this assumption and using a probable value for the dielectric constant of the membrane, the thickness of the membrane is calculated to be 3.3·10–7 cm.

Technical Solutions

The paper discusses new circuit solutions in the practice of electrochemical protection of pipelines. The aim of the work is to develop methods for measuring the polarization potential between the two control and measuring points of the pipeline under study. The main measurement methods are considered, a new method for measuring the polarization potential is proposed, based on local polarization current deviation using switched resistive circuits with subsequent mathematical processing of clock measurements. When implementing this method, it is possible to obtain additional information about the absolute value of the resistance of the soil in the control zone. In this paper, a new method of topographical referencing of the detected defect locations to the length of the pipeline under study is considered. Feature differences of the method are the use of a screened cable as a portable cable drum wire, the central core of which is used for galvanic connection of the pipeline with a voltmeter, and a braid for measuring the distance from the measuring point to the current position of the operator, as well as using a single time scale based on two Glonass / GPS receivers located respectively in the control and measuring point and the voltmeter carried by the operator. The proposed method is positioned a pipeline defect with a resolution of 0.1 m.
