Soil moisture is a key limiting resource in arid and semi-arid environments for woody shrub species. We assessed if three arid communities differed in their level of dry season soil moisture content and if the dominant species in these communities differed in their ability to use soil moisture. Water potential of all of the dominant woody plant species occurring in chaparral, coastal sage, and ...

In drinking water (DW) and the distribution systems, bacterial growth and biofilm formation have to be controlled both for limiting taste or odour development and preventing clogging or biocorrosion problems. After a contamination with undesired bacteria, factors like nutrient availability and temperature will influence the survival of these invaders. Understanding the conditions enabling invad...

LMS (Lernmanagement-Systeme) beinhalten bei flächendeckendem Einsatz kursspezifische Informationen, die bei der Erstellung und der Verwaltung von Vorlesungsaufzeichnungen umfangreiche Automatisierungspotenziale bieten. Durch Ansteuerung der Vorlesungsaufzeichnung aus dem LMS können Metadaten automatisch in die Aufzeichnung einfließen. Auch die Ansteuerung der zur Aufzeichnung benötigten Hörsaal...

To assess the scope for enhancing productivity of soybean (Glycine max L. Merr.), the CROPGRO-Soybean model was calibrated and validated for the diverse soybean-growing environments of central and peninsular India. The validated model was used to estimate potential yields (water non-limiting and water limiting) and yield gaps of soybean for 21 locations representing major soybean regions of Ind...

In present study, using Least Squares (LS) method, we determine the position smoothing in GPS single-frequency receiver by means of pseudo-range and carrier phase measurements. The application of pseudo-range or carrier phase measurements in GPS receiver positioning separately can lead to defects. By means of pseudo-range data, we have position with less precision and more distortion. By use of...

We present a new approach to combine two approaches to three-dimensional reconstruction: silhouette-based and correspondence-based approaches. The two approaches have complementary costs and benefits. Silhouette-based approaches deliver volumetric descriptions which often have very few outliers, but they cannot reconstruct concave surfaces. Correspondence-based approaches give surface descripti...

The sensitivity and accuracy to be expected from the ALMA water vapour radiometers is estimated. Even with quite pessimistic assumptions about noise temperature and gain stability, it appears that the sensitivity of the present design is at least a factor of 2 better than the specifications. It is more difficult to predict the medium term stability and accuracy that will be achieved, but the in...

This paper discusses some asymptotic uniform linearity results of randomly weighted empirical processes based on long range dependent random variables+ These results are subsequently used to linearize nonlinear regression quantiles in a nonlinear regression model with long range dependent errors, where the design variables can be either random or nonrandom+ These, in turn, yield the limiting be...
