Antipodal Vivaldi Antenna to Detect UHF Signals That Leaked Out of the Joint of a Transformer

In recent years, extensive research has been conducted on the ultrahigh-frequency (UHF) method. Considering that acquiring a partial discharge UHF signal is the first step in a series of tasks, such as fault diagnosis and defect location, the UHF sensor plays an important role in the UHF method. An antipodal Vivaldi antenna installed at a transformer’s joint is designed in this study according to the structural features of 750 kV transformers in China. Several effective structures, such as linear gradient microstrip and slot edge, are employed to improve the return loss and radiation characteristics. A metal box is designed after analyzing the influence of the metal around the antenna. The metal box can effectively shield against electromagnetic interference and does not deteriorate the performance of the antenna significantly. Experimental data show that this antenna is much more sensitive than the rectangular plane spiral antenna. The proposed antipodal Vivaldi antenna is suitable for detecting partial discharge in large transformers.
Parts and Packets Unification for Construction Automation and Robots

This paper proposes a method of configuration of database system for parts oriented construction. In parts oriented construction, robots acquire information related to the tasks from the server through ID attached to the construction components. This system aims (1) simplification in motion planning of the construction robots using information attached to components, (2) reconfiguration of data structure for process of construction tasks. The robot performs the tasks according to local planning based on the local information. The operation server reconfigure parts information based on task result by robots so that the next robot can obtain the required information from the composed components in the next phase. We call the parts integrated information “packets”, and call our idea “parts and packets unification. ” The feasibility of our proposed method is also shown in the preliminary experiments where an RFID tag attached to a component is applied for data exchange.
Automatic Extraction of Tissue Form in Brain Image

For simulation of surgical operations, extraction of selected regions from MR images requires a high level of skill and experience from the physicians. We have developed a unique automatic extraction algorithm for extracting three dimensional brain parenchyma from MR head images. This method has advantages compared with the morphological filtering (S ERRA, 1982, 1986; HARALIK et al., 1987) and the region growing method. As first step, this method was applied to binarized images, but there were some problems in that the results of extraction varied much with the value of the threshold level (SATO et al., 1997). As second step, the method was applied to gray scale image, but misextraction was caused because density in the contour of object change, locally. Finally, images having information corresponding to the property of human tissues, respectly, are introduced. The characteristics of this method is that an extracted form is not an exterior of the object, but the form of a set of picture element having a physical property. We could improve extraction accuracy. As a results, the over extracted ratio was improved by 36%, and the under extracted ratio was improved by 20%.
Evaluation of Tomato (Lycopersicon esculentum Mill) and Maize (Zea mays L.) Intercropping System for Profitability of the Crops in Wolaita Zone, Southern Ethiopia

Food shortage is known to have been caused by limiting factors such as inappropriate planting time, diseases and insect pests, use of low yielding varieties, etc in Ethiopia. In areas facing food insecurity, such as Africa, farmers have practiced intercropping since old times. The study was aimed to improve productivity and profitability of tomato/maize intercropping by determining their best compatible combination and right intercropping time for sustainable production of the crops in the area. Treatments consisted of factorial combinations of three component populations of tomato (T) and maize (M) i.e. (100T:50M, 67T:33M and 50T:50M) and five maize intercropping dates (30 DBTT, 15 DBTT, ATT, 15 DATT and 30 DATT) together with their respective sole crops and laid out as Randomized Complete Block Design (RCBD) with three replications. Determinate tomato and early maturing maize were used for the intercropping system. The highest total LER value of 2.06, with GMV of 171,077.73 Birr/ha and MA of 88,030.29 Birr/ha was obtained from component populations of 100T:50M. However, the highest GMV of 216,065.00 Birr/ha and MA of 144,044.00 Birr/ha was obtained from sole tomato crop. Although, sole tomato production would be beneficial in the study area, the 100% tomato population with 50% maize by intercropping maize 15 days after transplanting of tomato is a promising treatment in order to minimize risks where farmers fear risk of sole crop due to disease or market conditions.

Signatures of the self-affinity of fracture and faulting in pre-seismic electromagnetic emissions

Abstract. Of particular interest is the detection of precursors of an impending rupture. Theoretical, numerical studies along with laboratory experiments indicate that precursory signs of an impending failure are the sudden drop of fractal dimension and entropy, along with the anticorrelated, for large system sizes, rising of Hurst exponent and drop of a frequency–size power-law scaling exponent. Based on the widely accepted concept of the self-affine nature of faulting and fracture, we examine whether these precursory signs exist in the fracto-electromagnetic emissions resulting from the activation of a single fault.
Essays on Intermediation, Advertisement and Platform innovation

This thesis comprises three chapters in the area of intermediation, advertisement and platform innovation. Chapter 1, Quality Uncertainty, Uninformative Advertising and Intermediation Margins, works two contributions. First, we modify Milgrom and Roberts (1986) model of price and advertising as possible signals of an experience good quality, in such a way to rule out the possibility of price signalling alone. Second, the resulting, more tractable, model is then used to contrast the potential benefits of advertisement and intermediation, modelled as quality certification, as alternative ways to overcome information asymmetries on the quality of new experience goods. We show conditions under which intermediation can be a better way of revealing a product's true quality than advertising. Chapter 2, Platform innovation in a two-sided market, studies dynamic innovation incentives in two-sided markets. We present a monopoly platform model with service quality innovations and innovation models of competing platforms. We show that, in a non-tournament duopoly model, platforms will end up in a prisoners' dilemma equilibrium where they conduct same positive R & D, even if their profit will be higher without R & D investments. This result is derived assuming perfect ex-ante symmetry of the platform, and focusing on an ex-post symmetric equilibrium. We then present three extensions with asymmetric network externalities, platform exogenous specialization in side innovations, and innovation tournament model. Chapter 3, A note on Armstrong (2006) monopoly platform model, shows that the set of assumption in Armstrong (2006) monopoly platform model is not sufficient to guarantee the existence of an interior equilibrium with positive demands. We then show that the problem can be fixed by assuming that platform connections generate direct intrinsic value to the connected agents.
Chapter 7 TWO TYPES OF R I SK

The risk encountered in many environmental problems appears to exhibit special “two-sided” characteristics. For instance, in a given area and in a given period, farmers do not want to see too much or too little rainfall. They hope for rainfall that is in some given interval. We formulate and solve this problem with the help of a “two-sided loss function” that depends on the above range. Even in financial portfolio optimization a loss and a gain are “two sides of a coin”, so it is desirable to deal with them in a manner that reflects an investor’s relative concern. Consequently, in this paper, we define Type I risk: “the loss is too big” and Type II risk: “the gain is too small”. Ideally, we would want to minimize the two risks simultaneously. However, this may be impossible and hence we try to balance these two kinds of risk. Namely, we tolerate certain amount of one risk when minimizing the other. The latter problem is formulated as a suitable optimization problem and illustrated with a numerical example.
A PHOTOMETRIC STUDY OF FIVE OPEN CLUSTERS IN THE SDSS

We present a photometric study of five open clusters (Czernik 5, Alessi 53, Berkeley 49, Berkeley 84, and Pfleiderer 3) in the Sloan Digital Sky Survey. The position and size of these clusters are determined using the radial number density profiles of the stars, and the member stars of the clusters are selected using the proper motion data in the literature. We estimate the reddening, distance and age of the clusters based on the isochrone fitting in the color-magnitude diagram. The foreground reddenings for these clusters are estimated to be E(B - V ) = 0.71 - 1.55 mag. The distances to these clusters are derived to be 2.0 - 4.4 kpc, and their distances from the Galactic center range from 7.57 kpc to 12.35 kpc. Their ages are in the range from 250 Myr to 1 Gyr. Berkeley 49 and Berkeley 84 are located in the Orion spur, Czernik 5 is in the Perseus arm, and Pfleiderer 3 and Alessi 53 are located beyond the Perseus arm.
The Association between Anxiety and Professionalism in Residents of ENT Specialist Training Program in the Faculty of Medicine, Gadjah Mada University, Indonesia

Background: Professionalism has become a compulsory component of medical education, particularly due to the emergence of malpractice lawsuits. During specialist training programs, anxiety is one of the factors that affects education in professionalism. Anxiety is closely associated with stressors during training programs. The ear, nose and throat (ENT) specialist training program in the Faculty of Medicine Gadjah Mada University is known to be highly demanding with a heavy load of stressors. The broad area of competence and professionalism demand in ENT training made its residents prone to anxiety, which in turn affects their professionalism. In this study we measured professionalism and anxiety of residents in the ENT specialist training program and the association between them. Methods: This was a cross-sectional study. The subjects were active residents in the Department of Ear, Nose, and Throat, Faculty of Medicine, Gadjah Mada University who fulfilled the inclusion and exclusion criteria (n = 39). Professionalism was measured using the Resident Professionalism Inventory (RPI). Anxiety was measured using the Hamilton Anxiety Rating Scale (HARS). Data was coded and statistically analyzed using SPSS version 17. Statistical significance was defined as P < 0.05. Results: The prevalence of anxiety was very low. Most subjects reported insufficient professionalism (53.8%; 95% CI = 0.372–0.699). The results showed no association between anxiety and professionalism (P > 0.05). Conclusion: Anxiety was not associated with professionalism in ENT training program residents. Further study in other departments is required to confirm these results.
ETHNOZOOLOGICAL REMEDIAL USES BY THE INDIGENOUS INHABITANTS IN ADJOINING AREAS OF THE POBITORA WILDLIFE SANCTUARY, ASSAM, INDIA

Objective: To comprehend the traditional knowledge on zootherapeutic remedies used by indigenous people inhabiting in adjoining areas of the Pobitora wildlife sanctuary located in the Morigaon district of Assam State, India. Methods: [d1] The adjoining villages of this wildlife sanctuary are inhabited by different indigenous communities and tribal groups of which Nath community and Karbis constitute the main population. In the present study, field survey was carried out from October 2014 to March 2015 by performing personal interviews through semi-structured questionnaires and in some cases where respondents were uncomfortable with the questionnaires, informal interviews and group discussions were conducted with a total of 50 respondents (33 male and 17 female), who provided the information regarding various uses of animals and their products (local name of animal, mode of preparation, application, etc) in their traditional medicine. Results: A total of 26 ethnomedicinal animals and animal products that are used for the treatment of various ailments including asthma, jaundice, chicken pox, pneumonia, anemia, etc. were recorded. Some protected wild species like the golden jackal ( Canis aureus ), rhino ( Rhinoceros unicornis ) and Indian crested porcupine ( Hystrix indica ) were also mentioned to have important medicinal uses. The highest percentage of animals used for traditional treatment is mammals (~34.62 %) followed by fishes (~30.77 %) and birds (~15.38 %). Most of the information are generally provided by the elderly person in the age group above 50 y. Conclusion: The information on the remedial uses of different animals were collected from Nath community and Karbis who use a variety of zootherapeutic medicines for curing different ailments in their own ways. Such kind of information and documentation should be very helpful in the formulation of strategies on sustainable management and conservation of bio-resources so that the medicinal values of these traditional remedies would go a long way and may lead to novel drug(s) discovery.

LUX-ZEPLIN (LZ) is a next-generation dark matter direct detection experiment that will operate 4850 feet underground at the Sanford Underground Research Facility (SURF) in Lead, South Dakota, USA. Using a two-phase xenon detector with an active mass of 7 tonnes, LZ will search primarily for low-energy interactions with weakly interacting massive particles (WIMPs), which are hypothesized to make up the dark matter in our galactic halo. In this paper, the projected WIMP sensitivity of LZ is presented based on the latest background estimates and simulations of the detector. For a 1000 live day run using a 5.6-tonne fiducial mass, LZ is projected to exclude at 90% confidence level spin-independent WIMP-nucleon cross sections above 1.4×10-48 cm2 for a 40 GeV/c2 mass WIMP. Additionally, a 5σ discovery potential is projected, reaching cross sections below the exclusion limits of recent experiments. For spin-dependent WIMP-neutron(-proton) scattering, a sensitivity of 2.3×10-43 cm2 (7.1×10-42 cm2) for a 40 GeV/c2 mass WIMP is expected. With underground installation well underway, LZ is on track for commissioning at SURF in 2020.
Paternal Support of Emergent Literacy Development: Latino Fathers and Their Children

58 COPYRIGHT 2011 BY PSI CHI, THE INTERNATIONAL HONOR SOCIETY IN PSYCHOLOGY (VOL. 16, NO. 2/ISSN 1089-4136) Faculty Mentor: Gigliana Melzi ABSTRACT. Despite growing evidence supporting the notion that fathers influence their children’s education, few studies have examined the intersection of involvement and emergent literacy development. The present study explored the ways fathers (N = 12) support children’s literacy skills in a low-income Latino community. After completing self-report measures of daily involvement and home literacy, fathers shared a wordless book with their children. Fathers reported engaging in a variety of involvement activities, lending support to the study of fathering as a multifaceted construct. Furthermore, fathers provided rich linguistic environments during book-sharing. Trends among narrative participation scores support past literature suggesting cultural differences in narrative styles. Results provide important contributions to the limited literature on Latino parenting. Paternal Support of Emergent Literacy Development: Latino Fathers and Their Children Jackson J.

Some aspects of the crystal-chemistry of apatites

Abstract Twenty-four apatite (Ap) samples mainly from carbonatite and alkaline rocks were studied by electron microprobe, IR spectroscopy and X-ray powder diffraction. The crystal structures of six were refined using single crystal X-ray diffraction data to R = 1.7-2.5%. The generally high Si content of Ap from carbonatite and alkaline rock has been related to the presence of characteristic Si-O absorptions in IR spectra. Bands, whose intensities change with Si content, were observed at 520, 650, 930 and 1160 cm-1. The IR absorption features of v3 CO3 mode of Ap from carbonatite are different from those of v3 CO3 mode of Ap from sedimentary rock. This phenomenon is probably due to the different effects of F and OH on the CO3 substitution for PO4. The structural refinements yield more information on the CO3=PO4 substitution, which is now supported also by the geometrical evolution of the tetrahedron with increasing CO3 content: the tetrahedral size decreases and the angle distortion increases with C-content. It is likely that the triangular planar CO3 group is disordered on the four faces of PO4 3-tetrahedron. It was observed also that Ap from early-stage carbonatite is OH-dominant with considerable LREE, Si, CO3 and negligible Mn, Fe, Mg, K, S and C1 contents. They have high Sr/Mn, Si/S and C/S ratios.
Visco-plastic models of isothermal lava domes

The dynamics of expanding domes of isothermal lava are studied by treating the lava as a viscoplastic material with the Herschel–Bulkley constitutive law. Thin-layer theory is developed for radially symmetric extrusions onto horizontal plates. This provides an evolution equation for the thickness of the fluid that can be used to model expanding isothermal lava domes. Numerical and analytical solutions are derived that explore the effects of yield stress, shear thinning and basal sliding on the dome evolution. The results are briefly compared with an experimental study. It is found that it is difficult to unravel the combined effects of shear thinning and yield stress; this may prove important to studies that attempt to infer yield stress from morphology of flowing lava.
A comparative analysis of different procedures for measuring speech recognition threshold in quiet

In Slovenia, the adapted Freiburg Monosyllabic Word Test (FT-SI) has been used to assess the communication function in an audiology patient. To measure the speech recognition threshold (SRT), the ascending procedure that is applied in FT-SI may be very time consuming. The aim of our study was to compare several adaptive procedures with the FT-SI ascending procedure. Based on the analysis of comprehensibility and commonness of stimuli used in FT-SI, the most appropriate words were selected and used in three adaptive procedures: two variants of a descending procedure, both recommended by the ISO 8523-3 standards for measuring an SRT, and the staircase method. On a normal-hearing sample (N = 36 in test measurement and N = 24 in retest measurement), comparable SRTs were obtained with the adaptive procedures, whereas the FT-SI ascending procedure yielded slightly higher SRTs. When a selected pool of words was used in FT-SI, SRTs became more comparable to the results of the adaptive methods. The study therefore showed that the pool of words used in FT-SI should be revised. Considering relatively short administration time, satisfactory convergent validity, precision and test-retest reliability, the staircase method seems to be the best alternative to the FT-SI ascending procedure.
A new approach to the assessment of stochastic errors of radio source position catalogues

Assessing the external stochastic errors of radio source position catalogues derived from VLBI observations is important for tasks such as estimating the quality of the catalogues and their weighting during combination. One of the widely used methods to estimate these errors is the three-cornered-hat technique, which can be extended to the N-cornered-hat technique. A critical point of this method is how to properly account for the correlations between the compared catalogues. We present a new approach to solving this problem that is suitable for simultaneous investigations of several catalogues. To compute the correlation between two catalogues A and B, the differences between these catalogues and a third arbitrary catalogue C are computed. Then the correlation between these differences is considered as an estimate of the correlation between catalogues A and B. The average value of these estimates over all catalogues C is taken as a final estimate of the target correlation. In this way, an exhaustive search of all possible combinations allows one to compute the paired correlations between all catalogues. As an additional refinement of the method, we introduce the concept of weighted correlation coefficient. This technique was applied to nine recently published radio source position catalogues. We found large systematic differences between catalogues, that significantly impact determination of their stochastic errors. Finally, we estimated the stochastic errors of the nine catalogues.
Cointegration and co-feature analysis on electricity consumption and economic growth in China

The paper applies the cointegration theory to examine the causal relationship between electricity consumption and real GDP (Gross Domestic Product) for China during 1978-2004. Our estimation results indicate that real GDP and electricity consumption for China are cointegrated and there is only unidirectional Granger causality running from electricity consumption to real GDP but not the vice versa. Then H-P filter is applied to decompose the trend and cycle component of the GDP and electricity consumption series. The estimation results indicate that there is cointegration between not only the trend components, but also the cycle components of the two series, which implies that, the Granger causality is related with the business cycle. Then Granger causality between the cycle components indicates that there is bidirectional causality between them. The estimation results are of policy implication to the development of electric sector in China.
