The article represents results of a physical simulation of incomplete upward leader discharges induced on air transmission lines’ elements, using charged artificial thunderstorm cells of negative polarity. The influence of such discharges on closely located model sensors (both of rod and elongated types) of digital monitoring systems, as well as on the models of receiver-transmission systems of local data collection (antennas), was determined. Effect of heterogeneity of electromagnetic field caused by incomplete upward discharges on frequency specter of signals generated on sensors and antennas was estimated. Wavelet analysis was carried out to determine the basic frequency diapasons of such signals. Based on experimental data obtained, suppositions about the extent of influence of nearby incomplete leader discharges on the functioning of currently used systems of transmission lines’ monitoring were made.

Experimental Data Collection

Abstract Background Data handling in clinical bioinformatics is often inadequate. No freely available tools provide straightforward approaches for consistent, flexible metadata collection and linkage of related experimental data generated locally by vendor software. Results To address this problem, we created LabPipe, a flexible toolkit which is driven through a local client that runs alongside vendor software and connects to a light-weight server. The toolkit allows re-usable configurations to be defined for experiment metadata and local data collection, and handles metadata entry and linkage of data. LabPipe was piloted in a multi-site clinical breathomics study. Conclusions LabPipe provided a consistent, controlled approach for handling metadata and experimental data collection, collation and linkage in the exemplar study and was flexible enough to deal effectively with different data handling challenges.

Overhead Power Transmission Line

Methodology provided summarizes published, original and foreign theoretic and experimental data on the subject of heating and cooling of standard and shaped conductors of overhead power transmission line and uses those of them which are most affected to fundamental heat-transfer laws. Computation surface area of standard and shaped wire formulas are given. The common formula of convection heat transfer coefficient is provided, based on wind speed and direction, concerning antiicing mode. Parameters of this formula do not coincide with those existing, as they are based on experimental data on standard and shaped conductors but not on round tubes. Formula of computation of heat transfer power under the influence of solar radiation is given. Summarized formula of admissible continuous current computation is given, all the components have detailed description in the article.

A measure is proposed for the information content of data with respect to models. A model, defined by a set of parameter values in a mathematical framework, is considered a point in a hyperspace. The proposed measure expresses the information content of experimental data as the contribution they make, in units of information bits, in defining a model to within a desired region of the hyperspace. This measure is then normalized to conventional statistical measures of uncertainty. It is shown how the measure can be used to estimate the information of newly planned experiments and help in decisions on data collection strategies.

During this time many people were found to achieve the required high learningachievement intellectual intelligence (IQ) is also high. However, EQ good can determine thesuccess of individuals in learning achievement in building a successful career, and can reducethe aggressiveness, especially among teenagers purpose of this study was to determinewhether there is a relationship of emotional intelligence toward student learning achievementProdi DIII Midwifery Curup Semester II and IV. This research was conducted in the ProdiDIII Midwifery Curup from July to August 2016, with the number of respondents, thisresearch is descriptive analytic, data collection using a scale based on the theory of emotionalintelligence Daniel Goleman; to measure student achievement used methods of examinationof documents by the second half saw the value of IP, IV and population II and IV semesterstudent, taken by total population, the data was analyzed by univariate and bivariate. Theresults of the analysis of experimental data showed correlation coefficient of 0.635 with p0.005 (<0.05), the Ha accepted. This means that there is a significant relationship betweenemotional intelligence and academic achievement of students Prodi DIII Midwifery Curup IIand IV semester of 2016. To develop and optimize the emotional intelligence plays a role instudent success both in school and in the surrounding environment, it is recommended to thecampus, especially the lecturer-dosenagar incorporate elements emosioal intelligence inpresenting the material as well as the emotions involved in the learning process
