This paper summarize about the auxiliary electrode measured a ground resistance The method to measure a ground resistance is the fall-of-potential method to using an auxiliary electrode. And an auxiliary electrode must be set up on the ground. Today it is so difficult to set up the auxiliary electrode on the ground because of many concrete building and many paved roads. So this paper is regarding of the ground resistance measurement by the substitute auxiliary electrode. It substituted a iron structure around the building, a wire net for auxiliary electrode. This information is confirmed by compared with the measurement value.

We conducted a study on a regression spline estimator with a few pre-specified auxiliary variables. For the implementation of the proposed estimators, we adapted a coordinate descent algorithm. This was implemented by considering a structure of the sum of the residuals squared objective function determined by the B-spline and the auxiliary coefficients. We also considered an efficient stepwise knot selection algorithm based on the Bayesian information criterion. This was to adaptively select smoothly functioning estimator data. Numerical studies using both simulated and real data sets were conducted to illustrate the proposed method's performance. An R software package psav is available.

Korean auxiliary verbs are often used in Korean sentences in spite of the small number of the auxiliary verbs, However. the incorrect processing of the verbs concept leads to the poor translation quality. To solve the problems of the auxiliary verb processing. the paper proposes a description of the auxiliary verbs based on Conceptual Graph (CG), For the description of the auxiliary verbs within CG. we first collect 40 Korean auxiliary verbs and example sentences from papers and a Korean dictionary, Next, we perform the analysis of the Korean auxiliary verbs through a classification: perfective, progressive, benefactive, attemptive, emphatic, desirable, retentive, and presumptive. Then we depict the eight meanings based on CG. In the experiment. the paper implements the program that translates sentences included in the auxiliary verbs into CG and explains the experimental results.

The purpose of this study is to analyze and compare of the structure of auxiliary schedules using in DDC, UDC, CC and BC. Auxiliary schedule whish are a n.0, ppended to schedule of all schemes of classification. They consist of items of form of presentation relationship, time, place, languages, racial, ethnic, national groups and persons and phase relation and the symbols of the different items can be added to classification numbers.

For estimating the mean of a finite population, three classes of estimators using multi-auxiliary information with unknown means using two phase sampling in presence of non-response have been proposed with their properties. Asymptotically optimum estimator(AOE) in each class has been identified along with their mean squared error formulae. An empirical study is also given.

This study aims to derive practical suggestions to apply application methods by auxiliary costs, especially application of logistics and customs clearance areas in order to establish EPS support system of auxiliary cost occurred from export/import. For the propose, this study has analyzed types and situation of auxiliary costs, application method by auxiliary costs, payment situation of logistics auxiliary costs and clearance auxiliary costs and suggested the relevant problems and their application methods. Especially, in case of logistics auxiliary costs through connection to the attached general documents required for negotiation by reflecting characteristics of B2B transactions. In addition, it has suggested that those services by the said system should be conveniently used commonly by the export companies and logistics companies through provision of various payment measures, support of foreign currency payment, etc. and security of reliability/system stability, etc. for the compatible payment with other systems as the prerequisite for the successful settlement of the auxiliary costs EPS. It is expected that satisfaction of the uTradeHub users such as export/import companies and logistics companies will be increased, user-oriented customized information services such as raw cost prediction service through calculation of auxiliary costs could be available in the future and efficiency of work processes related to auxiliary costs will be increased, by providing the EPS through various single window based payment measures through establishment of the export/import auxiliary costs payment system.

In this study, a new dual-active soft-switching converter is proposed to improve conversion efficiency and extend the load range for an MTEM electromagnetic transmitter in geological exploration. Unlike a conventional DC/DC converter, the proposed converter can operate in passive soft-switching, single-active soft-switching, or dual-active soft-switching modes depending on the change in load power. The main switches and lagging auxiliary switches of the converter can attain soft-switching over the entire load range. The conduction and switching losses are greatly reduced compared with those of ordinary converters under the action of the cut-off diodes and auxiliary windings coupled to the main transformer in the auxiliary circuits. The conversion efficiency of the proposed converter is significantly improved, especially under light-load conditions. First, the working principle of the proposed converter is analyzed in detail. Second, the relationship between the different operating modes and the load power is given and the design principle of the auxiliary circuit is presented. Finally, the Saber simulation and experimental results verify the feasibility and validity of the converter and a 50 kW prototype is implemented.

Most sentiment analysis systems count the number of occurrences of sentiment expressions in a text, and evaluate the text by summing polarity values of extracted sentiment expressions. However, linguistic contexts of the expressions should be taken into account in order to analyze sentimental orientation of the text meticulously. Korean auxiliary predicates affect meaning of the main verb or adjective in some ways while attached to it in their usage. In this paper, we introduce a new approach that handles Korean auxiliary predicates in the light of sentiment analysis. We classify the auxiliary predicates according to their strength of impact on sentiment polarity values. We also define compositional rules of auxiliary predicates to update polarity values when the predicates appear along with sentiment expressions. This approach is implemented to a sentiment analysis system to extract opinions about a specific individual from review documents which were collected from various web sites. An experimental result shows approximately 72.6% precision and 52.7% recall for correctly detecting sentiment expressions from a text.

This paper presents numerical analysis of measurement errors of ground electrode using the fall-of-potential method. In order to analyze ground resistance error according to the positions of auxiliary probes, firstly, national and international standards were researched. Secondly, numerical ground resistance error of hemispheric electrode was analyzed according to the locations of auxiliary probes and the angle between probes. Then, error-reduced positions of auxiliary probes were shown according to the distance to auxiliary current probe versus ground electrode size. Finally, error compensation method was presented. The results presented in this paper provide useful information regarding ground resistance error of alternative positions of auxiliary probes in case that the auxiliary probes could not be located at the proper position in such cases as there are buildings, roadblock or underground metallic pipe at that position.

The transition of auxiliary lines for transmitting coding information has been one of the major obstacles to restricting the scalability of Sequence Switch Coding (SSC) algorithms. A new design of SSC which does not use auxiliary lines is presented in this paper. The new design makes overhead transitions far less than the previous designs that use auxiliary lines. By applying the new technique, more than 50% of overhead transitions have been reduced, leading to the increase of 30% of the overall efficiency of SSC algorithm.
