Effect of Cover Crops, and the Management Thereof, on the Weed Spectrum in a Drip-irrigated Vineyard: 2. Weeds Growing From Grapevine Berry Set to Post-harvest

A five-year trial (2009 to 2013) was executed in a drip-irrigated seven-year-old Shiraz/101-14 Mgt vineyard established on a sandy to sandy clay loam soil at Blaauwklippen Farm (33°58’S, 18°50’E) near Stellenbosch, South Africa. Fourteen treatments, consisting of two management practices applied to five cover crop species, as well as winter-growing weeds (no cover crop) and winter-growing weeds (no cover crop) with nematicide applied in the vine row, were applied. The weeds and cover crop species were eithercontrolled chemically (CC) or mechanically (MC) during grapevine bud break, followed by full-surface chemical control during berry set (for both CC and MC treatments). Rhynchelytrum repens (Natal redtop)dominated the post-harvest pre-treatment weed spectrum in all the treatments except Eruca sativa cv. Nemat (Nemat) (MC). This species lost its post-harvest dominance from 2010 onwards. It seems that the relatively low summer rainfall during the 2010/2011 season allowed Anagallis arvensis to appear in April 2011 and dominate some of the treatments, which coincided with the disappearance of Cynodon dactylon (common couch) and Polygonum aviculare (prostrate knotweed). Digitaria sanguinalis, common couch and prostrate knotweed seemed to establish better during late summer where MC was applied. The pre-treatment average post-harvest weed stand of 5.53 t/ha was reduced to 0.53 t/ha within one season, illustrating the benefit of full-surface chemical weed control applied during grapevine berry set

A dual process account of creative thinking

This article explicates the potential role played by type 1 thinking (automatic, fast) and type 2 thinking (effortful, logical) in creative thinking. The relevance of Evans's (2007) models of conflict of dual processes in thinking is discussed with regards to creative thinking. The role played by type 1 thinking and type 2 thinking during the different stages of creativity (problem finding and conceptualization, incubation, illumination, verification and dissemination) is discussed. It is proposed that although both types of thinking are active in creativity, the extent to which they are active and the nature of their contribution to creativity will vary between stages of the creative process. Directions for future research to test this proposal are outlined; differing methodologies and the investigation of different stages of creative thinking are discussed. © Taylor & Francis Group, LLC

Unterstützung kommunalplanerischer Prozesse mit CityGLM-basierter Anbindung Modelica-getriebener Quartierssimulationen

Eine integrale Planung städtischer (Energie-)Systeme bedarf einer planungsbegleitenden Unterstützung durch IT-basierte Planungs- und Simulationswerkzeuge. Die durchgängige Anwendung dieser digitalen Planungshilfsmittel wird allerdings bislang insbesondere durch den sehr hohen Aufwand bei der Spezifizierung und Erfassung benötigter Datengrundlagen sowie eine mangelhafte Interoperabilität zwischen den Systemen gehemmt. Im Rahmen eines Forschungsverbundprojektes wird dieses Problemfeld mittels praxisbezogener Prozessanalysen genauer spezifiziert und die technische und fachliche Integration durch die prozessbezogene Spezifikation relevanter Informationsbedarfe sowie die Entwicklung einer darauf aufbauenden, bidirektionalen Schnittstelle auf Basis des etablierten virtuellen Stadtmodellstandards CityGML verbessert. Als exemplarisches Anwendungsszenario innerhalb kommunaler Planungsprozesse wurde die Ausweisung von Vorranggebieten der Fernwärmenutzung basierend auf einer räumlichen Analyse des Wärmebedarfs für verschiedene Entwicklungsszenarien mittels einer bidirektionalen standard-basierten Koppelung von CityGML und Modelica ausgearbeitet

Numerical Weather Prediction (NWP) and hybrid ARMA/ANN model to predict global radiation

We propose in this paper an original technique to predict global radiation using a hybrid ARMA/ANN model and data issued from a numerical weather prediction model (ALADIN). We particularly look at the Multi-Layer Perceptron. After optimizing our architecture with ALADIN and endogenous data previously made stationary and using an innovative pre-input layer selection method, we combined it to an ARMA model from a rule based on the analysis of hourly data series. This model has been used to forecast the hourly global radiation for five places in Mediterranean area. Our technique outperforms classical models for all the places. The nRMSE for our hybrid model ANN/ARMA is 14.9% compared to 26.2% for the na\"ive persistence predictor. Note that in the stand alone ANN case the nRMSE is 18.4%. Finally, in order to discuss the reliability of the forecaster outputs, a complementary study concerning the confidence interval of each prediction is proposedComment: Energy (2012)
