MAPPING AND SIMULATING SYSTEMATICS DUE TO SPATIALLY VARYING OBSERVING CONDITIONS IN DES SCIENCE VERIFICATION DATA

Spatially varying depth and the characteristics of observing conditions, such as seeing, airmass, or sky background, are major sources of systematic uncertainties in modern galaxy survey analyses, particularly in deep multi-epoch surveys. We present a framework to extract and project these sources of systematics onto the sky, and apply it to the Dark Energy Survey (DES) to map the observing conditions of the Science Verification (SV) data. The resulting distributions and maps of sources of systematics are used in several analyses of DES–SV to perform detailed null tests with the data, and also to incorporate systematics in survey simulations. We illustrate the complementary nature of these two approaches by comparing the SV data with BCC-UFig, a synthetic sky catalog generated by forward-modeling of the DES–SV images. We analyze the BCC-UFig simulation to construct galaxy samples mimicking those used in SV galaxy clustering studies. We show that the spatially varying survey depth imprinted in the observed galaxy densities and the redshift distributions of the SV data are successfully reproduced by the simulation and are well-captured by the maps of observing conditions. The combined use of the maps, the SV data, and the BCC-UFig simulation allows us to quantify the impact of spatial systematics on N(z), the redshift distributions inferred using photometric redshifts. We conclude that spatial systematics in the SV data are mainly due to seeing fluctuations and are under control in current clustering and weak-lensing analyses. However, they will need to be carefully characterized in upcoming phases of DES in order to avoid biasing the inferred cosmological results. The framework presented here is relevant to all multi-epoch surveys and will be essential for exploiting future surveys such as the Large Synoptic Survey Telescope, which will require detailed null tests and realistic end-to-end image simulations to correctly interpret the deep, high-cadence observations of the sky.
Relevance feature discovery for text analysis

It is a big challenge to guarantee the quality of discovered relevance features in text documents for describing user preferences because of the large number of terms, patterns, and noise. Most existing popular text mining and classification methods have adopted term-based approaches. However, they have all suffered from the problems of polysemy and synonymy. Over the years, people have often held the hypothesis that pattern-based methods should perform better than term- based ones in describing user preferences, but many experiments do not support this hypothesis. This research presents a promising method, Relevance Feature Discovery (RFD), for solving this challenging issue. It discovers both positive and negative patterns in text documents as high-level features in order to accurately weight low-level features (terms) based on their specificity and their distributions in the high-level features. The thesis also introduces an adaptive model (called ARFD) to enhance the exibility of using RFD in adaptive environment. ARFD automatically updates the system's knowledge based on a sliding window over new incoming feedback documents. It can efficiently decide which incoming documents can bring in new knowledge into the system. Substantial experiments using the proposed models on Reuters Corpus Volume 1 and TREC topics show that the proposed models significantly outperform both the state-of-the-art term-based methods underpinned by Okapi BM25, Rocchio or Support Vector Machine and other pattern-based methods.
Temperament in Adults-Reliability, Stability, and Factor Structure of the EAS Temperament Survey

We assessed the factor structure and psychometric properties of the Emotionality, Activity, and Sociability (EAS) Temperament Survey (Buss & Plomin, 1984) for adults using a longitudinal sample of adult women. The stability estimates of the EAS instrument were assessed over a period of 3 years. The results indicated an acceptable fit for the basic theoretical EAS model, implying that the scale is functioning satisfactory. However, the results also suggest that the measure could be improved. Across time, latent stability factors explained within-scale covariances. Both latent stability factors and time-specific factors accounted for cross-sectional covariances between subscales. Additional research is warranted to guide the further development of the EAS model.
Enzymic Analysis of Feruloylated Arabinoxylans (Feraxan) Derived from Zea mays Cell Walls : II. Fractionation and Partial Characterization of Feraxan Fragments Dissociated by a Bacillus subtilis Enzyme (Feraxanase).

Structural features of feruloylated arabinoxylan (feraxan) present in Zea mays L. (hybrid B 73 x Mo 17) coleoptile cell walls have been studied using a purified feraxan-dissociating enzyme (feraxanase) and an alpha-arabinofuranosidase. This experimental approach has demonstrated the following. (a) Feraxanase dissociated ca. 20% (dry weight basis) of the maize wall preparation. The predominant oligosaccharides enzymically liberated were allocated into seven major subfractions designated A-1 (0.8%), B-1 (1.6%), B-2 (2.4%), B-3 (4.6%), C-1 (1.0%), C-2 (4.2%), and C-3 (0.3%). Values in parentheses reflect the percentage of the wall associated with each subfraction. Subfractions represent samples enriched in different degrees of polymerization, sugar composition, linkage arrangements, and phenolic acid content. (b) B-1, B-2, and B-3 fractions are not feruloylated and have smaller molecular mass (less than 10(4) kilodaltons) and consist chiefly of t-arabinosyl-5-arabinosyl, 4-xylosyl, 2,4/3,4-xylosyl, and glucuronosyl residues, suggesting that these fragments constitute nonferuloylated regions of arabinoxylan. (c) C-2 and C-3 fractions contain ferulic acid (6.2% and 12.1%, respectively) and are similar to the B series in their sugar linkage arrangements but were derived from feruloylated regions. (d) Alkali treatment of the C-2 fraction decreases the molecular size of the fragment and liberates phenolic acids. The results suggest the presence of alkaline-labile links, probably diferulate bridges. (e) A-1 and C-1 fractions are larger (more than 5 x 10(5) kilodalton) and contain t-galactosyl-, 4-galactosyl, 2,4-rhamnosyl-residues, galacturonic acid, and the sugar linkage arrangements common to other fractions. The A-1 fraction is not feruloylated, whereas C-1 fraction contains 0.5% ferulic acid. The presence of galactose, rhamnose, and galacturonic acid suggests that pectic polymers, probably homopolygalacturonans and rhamnogalacturonans, are linked to nonferuloylated and feruloylated segments of arabinoxylans.
STUDIES OF BASIN STRUCTURES ALONG THE EASTERN FRONT OF THE SIERRA NEVADA , CALIFORNIAt ]

A seismic and gravity survey along the eastern front of the Sierra Nevada, California, between southern Owens Valley and the Garlock fault, outlines a series of basins with maximum depths ranging from 5,000 to 9,000 ft. These basins follow the front of the Sierra Nevada in a continuous chain with one interruption of about 10 miles near Little Lake. The gravity anomalies indicate that the basins are bounded by a series of high-angle faults rather than a single large fault. The seismic velocities in the basin deposits appear to correlate with the stratigraphy of the section exposed in the El Paso Mountains. A comparison of Bouguer anomalies with seismic depths indicates a density contrast of 0.35 g/cc in basins less than 3,000 ft deep, and an average but widely varying density contrast of 0.25 g/cc in basins 4,000 to 8,000 ft deep. A digital-computer program for automatic computation of basin depths from gravity anomalies was evaluated and found to be useful in this type of analysis. Changes in the depth to the Mohorovicic discontinuity cannot produce regional gradients as large as the regional gradients observed in the area of the survey. Either structure on an intermediate crustal boundary or lateral changes in crustal densities, or a combination of these, is required to explain the gravity data.
Professional knowledge and skills on addictions brief intervention by distance training

Translational research represents a sequence of events where the professional learn to apply their knowledge until get measure from the effects of the treatment on the clients [1,2]. On this matter, Dissemination refers to create a technology from an innovation to facilitate the distribution of the information process. In second place, Implementation represents a group of designed specific activities to put an innovation in use, and promote the needed resources to actual and potential applications. Finally, the Diffusion is the process that allows the adoption of new practices and decision-making based on empirical evidence. So the dissemination of the information makes possible the health professional’s transformation to develop the interventions adoption based on evidence [3]. Then, there is necessary to find effective ways of disseminate the procedures to assure health care [4]. The information and communication and technologies (ICT) use constitute the tools to disseminate the information to solve significant social and health problems as drugs dependence [5]. So, the use of ICT is a tool to train professionals to use based evidence practices in clinical settings.

This paper presents a load flow solution for three phase unbalanced radial distribution feeder using MATLAB/Simulink software. Further a comparison between Simulink load flow analysis and solution provided by IEEE distribution system analysis subcommittee for various configurations has been done. Newton-Raphson method for load flow analysis has been used. The IEEE 13 and 34 node test feeder models are used for comparison purposes because these models includes all possible practical configurations and load profiles such as three phase asymmetry, single phase lateral and distributed loads, among others. Results show the voltage magnitude and voltage angle at various load buses with minimum losses.

Controller augmentation and test point insertion at RTL for concurrent operational unit testing

Test point insertion methods to reduce the number of test patterns at register transfer level are required for the adaptability of traditional VLSI design flows and the reduction of time to search test point locations. In this paper, we propose a design-for-testability method at register transfer level to enable operational units as many as possible to be concurrently tested in scan testing. Using test point insertion and controller augmentation, the proposed design-for-testability method allocates input test registers and an output test register to inputs and an output of each operational unit in a data-path, respectively. Test compaction efficiency becomes high by enabling effective concurrent testing for operational units. Experimental results on high-level benchmark circuits show that our proposed method reduced the number of test patterns by 20% with 6.5 % area overhead on average.
Development of usability and context-of-use taxonomies, integration with techniques for the study of usability and application to real-world intelligent systems

Un importante obstaculo para la implantacion del Diseno Centrado en el Usuario en el mundo real es que no existe una definicion del concepto de usabilidad que sea precisa y comunnmente aceptada y aplicada en la practica. La literatura tiende a definir la usabilidad en terminos demasiado escuetos y ambiguos, y a describir su aplicacion en terminos informales. Identicas criticas pueden hacerse al concepto del contexto de uso, al cual la usabilidad es siempre relativa. Como consecuencia de esto, las tecnicas ad hoc predominan en las metodologias de usabilidad. Esta tesis propone taxonomias detalladas para los conceptos de usabilidad y contexto de uso. Las taxonomias estan organizadas jerarquicamente y contienen descripciones precisas de sus atributos y subatributos. Para ilustrar la utilidad practica de las taxonomias, se describe como fueron integradas en el ciclo de vida de desarrollo de dos productos reales en el campo de los Sistemas Inteligentes. Concretamente, un dispositivo de Adaptacion Inteligente de la Velocidad y un generador automatico de interfaces de usuario. En un punto especifico de cada proyecto se realizo un estudio de usabilidad, usando las taxonomias para estructurar y guiar actividades de usabilidad como el analisis de los requisitos de usabilidad, la evaluacion heuristica y el analisis subjetivo.
A burst search for gravitational waves from binary black holes

Compact binary coalescence (CBC) is one of the most promising sources of gravitational waves. These sources are usually searched for with matched filters which require accurate calculation of the GW waveforms and generation of large template banks. We present a complementary search technique based on algorithms used in un-modeled searches. Initially designed for detection of un-modeled bursts, which can span a very large set of waveform morphologies, the search algorithm presented here is constrained for targeted detection of the smaller subset of CBC signals. The constraint is based on the assumption of elliptical polarization for signals received at the detector. We expect that the algorithm is sensitive to CBC signals in a wide range of masses, mass ratios and spin parameters. In preparation for the analysis of data from the fifth LIGO-Virgo science run (S5), we performed preliminary studies of the algorithm on test data. We present the sensitivity of the search to different types of simulated binary black hole waveforms. Also, we discuss how to extend the results of the test run into a search over all of the current LIGO-Virgo data set.
Small Square Monopole Antenna With Enhanced Bandwidth by Using Inverted T-Shaped Slot and Conductor-Backed Plane

We present a novel printed monopole antenna for ultra wideband applications. The proposed antenna consists of a square radiating patch with an inverted T-shaped slot and a ground plane with an inverted T-shaped conductor-backed plane, which provides a wide usable fractional bandwidth of more than 130% (2.91-14.1 GHz). By cutting a modified inverted T-shaped slot with variable dimensions on the radiating patch and also by inserting an inverted T-shaped conductor-backed plane, additional resonances are excited and hence much wider impedance bandwidth can be produced, especially at the higher band. The designed antenna has a small size of 12 × 18 mm2 . Simulated and experimental results obtained for this antenna show that it exhibits good radiation behavior within the UWB frequency range.
The 21st Century Campus Map: Mapping the University of Wisconsin-Madison

Abstract We present two interactive, online maps of the University of Wisconsin-Madison campus: The University of Wisconsin-Madison Interactive Campus Map (http://map.wisc.edu) and the Lakeshore Nature Preserve Interactive Map (http://www.lakeshorepreserve.wisc.edu). Although these two projects represent the same university campus, the former follows a wayfinding-based model of campus mapping while the latter follows an atlas-based model of campus mapping. The purpose of the University of Wisconsin-Madison Interactive Campus Map is to search for, navigate to, and retrieve information about specific features on campus. The purpose of the Lakeshore Nature Preserve Campus Map is to present the rich history and unique geography of the University's Lakeshore Nature Preserve. Both maps were produced by the University of Wisconsin-Madison Cartography Laboratory and developed primarily in Flash 8 using ActionScript 2.0. We hope that the University of Wisconsin-Madison Interactive Campus Map and Lakeshore Nature Preserve Interactive Map provide guidance through example for those undertaking similar projects
Pharmaceutical formulation of a fixed-dose anti-tuberculosis combination.

SETTING Department of Pharmacy and Pharmacology, University of the Witwatersrand. Despite the availability of highly effective treatment regimens for tuberculosis (TB), the cure rate still remains relatively low. This may be attributed to the high incidence of patient non-compliance, which subsequently leads to the emergence of multidrug-resistant TB (MDR-TB). To avoid the problem of further creation and propagation of MDR-TB, it may be proposed that patients should be given fixed-dose combinations of anti-tuberculosis drugs whenever self-administration is permitted. OBJECTIVE To optimise an anti-tuberculosis extemporaneous powder formulation for suspension in order to develop a fixed combination of rifampicin, isoniazid, pyrazinamide and ethambutol hydrochloride as a powder to be reconstituted with water by the patient prior to administration. METHODS Different suspending agents were evaluated for their influence on powder flow properties, and sediment volume on the powder blends. Sodium starch glycolate was selected as the suspending agent because of its favourable powder flow properties and sediment volume produced. The dissolution characteristics of the extemporaneous powder for suspension were also compared to the dissolution profiles of commercially available anti-tuberculosis tablet dosage forms. RESULTS The powder for suspension for rifampicin, isoniazid, pyrazinamide and ethambutol hydrochloride all compared favourably to the dissolution rate from the commercially available tablet dosage forms.
Medição do teor de humidade em materiais de construção

A humidade e uma das principais causas de patologias em edificios. Neste trabalho pretende-se sensibilizar os intervenientes da construcao para a importância do teor de humidade de materiais de construcao e para a sua determinacao experimental.O teor de humidade e um parâmetro importante para a engenharia civil, requer cuidados em projecto, na execucao e no controlo de qualidade. A sua especificacao em projecto e o seu controlo na execucao sao decisivos, pelo que e necessario o conhecimento das propriedades fisicas e higrotermicas dos materiais de construcao, de forma a evitar a sua degradacao precoce. Nao e admissivel que os actores da construcao continuem a usar materiais dos quais desconhecem as propriedades.Apresentam-se as diferentes formas de expressao do teor de humidade, bem como as definicoes dos diferentes niveis de teor de humidade que um material pode atingir. Elaborou-se um quadro com as propriedades dos materiais de construcao correntes (valores de referencia), baseadas nas escassas referencias bibliograficas disponiveis, o que demonstra claramente a necessidade de investigacao nesta area. Estabeleceu-se a ligacao entre o teor de humidade e a simulacao numerica, pois os programas de calculo automatico sao ferramentas essenciais para a investigacao de novos materiais, ou simplesmente para simular o comportamento dos materiais face a diferentes solicitacoes.Na parte principal deste trabalho apresentam-se onze tecnicas de ensaio para a determinacao do teor de humidade, cada uma com as suas vantagens e inconvenientes. Apresenta-se o principio de medicao (fisica), o equipamento experimental e a sua calibracao, bem como o procedimento de ensaio e os erros de medicao associados. Salienta-se que a maioria dos equipamentos apresentados nao esta disponivel no Laboratorio de Fisica das Construcao da Faculdade de Engenharia da Universidade doPorto (LFC - FEUP) e sao pouco conhecidos em Portugal. Assim sendo, o trabalho desenvolvido procura melhorar os conhecimentos ligados a determinacao experimental do teor de humidade.Realca-se que a escolha da tecnica adequada, depende do material/ elemento a analisar e da precisao pretendida.Tendo em conta a necessidade crescente de utilizacao de equipamentos de medicao do teor de humidade, propoe-se um modelo de fichas de ensaio para poderem ser aplicadas em obra ou em laboratorio, que explicam de forma sucinta como realizar o ensaio, quais os equipamentos necessarios e como interpretar os resultados obtidos. As fichas estao organizadas e redigidas de modo a que qualquer utilizador, independentemente do nivel de formacao, interpreta a informacao disponibilizada.Finalmente, com alguns dos equipamentos de medicao disponiveis no LFC realizou-se um ensaio muito simples com provetes de pedra calcaria, que permitiram a familiarizacao com os aparelhos ecom as dificuldades de medicao e manuseamento que estes envolvem, bem como a interpretacao dos resultados obtidos.PALAVRAS-CHAVE: Tecnicas experimentais, Teor de humidade.
