    Content: Das Mobilfunksystem GSM (Global System for Mobile Communication) wurde von Anfang an sehr erfolgreich in ganz Europa und auch in vielen außereuropäischen Ländern eingesetzt. Es ist mittlerweile zu einem wirklich globalen System herangewachsen - der GSM-Anteil am Weltmarkt der digitalen Mobilfunksysteme betrug Ende 1998 über 60% und die Teilnehmerzahlen hatten sich innerhalb eines Jahres verdoppelt. Das Buch stellt auf der Grundlage der europäischen GSM-Standards die technischen Grundlagen und die Systemarchitektur von GSM vor. Dabei liegen die Schwerpunkte auf der Darstellung der Protokolle, der Mobilvermittlungstechnik und der Dienstrealisierung. Die wichtigsten Prinzipien der GSM-Übertragungstechnik werden ebenfalls behandelt. Die erweiterte und aktualisierte Neuauflage enthält zusätzlich vor allem eine ausführliche Beschreibung des General Packet Radio Service (GPRS) und einen aktuellen Überblick zum Stand der Entwicklung der dritten Mobilfunkgeneration UMTS/IMT-2000. Angesprochen sind Studierende der Elektrotechnik, Informationstechnik und Informatik von Universitäten und Fachhochschulen, Anwender und Praktiker aus der Industrie, von Netzbetreibern und aus der Forschung, die sich einen fundierten Einblick in die Funktionsweise des komplexen Systems GSM verschaffen wollen und vor allem am Zusammenspiel der verschiedenen Funktionen interessiert sind.

    Content: Wo und wie schnell nehmen Wurzeln Wasser auf? Obwohl diese Frage in Pflanzen- und  Bodenwissenschaften von großer Bedeutung ist, gibt es nur wenige experimentelle Daten darüber, an welcher Stelle der Wurzeln eine transpirierende Pflanze das Wasser aus dem Boden erhält. Die Antwort auf diese Frage erfordert direkte und in-situ Messungen des lokalen Wasserflusses in die Wurzel hinein. Ziel dieser Arbeit war es, eine neue Methode zu entwickeln und anzuwenden, um den lokalen Wasserfluss in unterschiedliche Segmente der Pflanzenwurzeln zu quantifizieren. Dabei wurde Neutronenradiographie eingese...
    Content: Where and how fast do roots take up water? Despite its importance in plant and soil sciences, there is limited experimental information on the location of water uptake along the roots of transpiring plants growing in soil. The answer to this question requires direct and in-situ measurement of the local flow of water into the roots. The aim of this study was to develop and apply a new method to quantify the local fluxes of water into different segments of the roots of intact plants. To this end, neutron radiography was used to trace the transport of deuterated water (D2O) into the roots of l...

    Combined impact of soil heterogeneity and vegetation type on the annual water balance at the field scale (18)

    Content: The hydraulic behavior of soil is determined by its hydraulic properties and their variability in space. In agricultural soils, this heterogeneity may stem from tillage or may have natural origin. The root distribution of plants will adapt to some extent to this soil heterogeneity. However, the combined impact of soil heterogeneity and root water uptake (RWU) on long-term soil water budgets has not received much attention. Numerical experiments helped identify how soil heterogeneity affects plant transpiration, soil evaporation, and groundwater recharge. Two-dimensional virtual soils with hierarchical heterogeneity, both natural and tillage induced, served as a basis for modeling soil water dynamics for a 10-yr climate record from two weather stations in Germany that vastly differ in annual precipitation. The complex interactions between soil and vegetation were explored by (i) comparing different RWU strategies (depth-, structure-, and time-dependent root profiles), (ii) land use types (perennial grass and annual winter crops), (iii) a combination of textures (silt above sand and sand above loam), and (iv) RWU with or without a compensation mechanism. The simulations were repeated with one-dimensional, effective representations of these virtual soils. In the framework of hydropedology, this study shed some light on the interaction between plants and pedological features and its impact on the macroscopic soil water budget. We demonstrated that land use has a major impact on the annual water balance through the partitioning of evapotranspiration into bare soil evaporation and plant transpiration. Compensational RWU becomes important for the annual water balance when the root zone comprises contrasting materials with respect to water holding capacity. Soil heterogeneity has in fact a minor impact on long-term soil water budgets. As a consequence, the relative contribution of plant transpiration, soil evaporation, and groundwater recharge to the total soil water loss was well reproduced by simulations in one-dimensional effective soil profiles. This advocates the application of one-dimensional soil-atmosphere-vegetation transfer (SVAT) models at larger scales. These findings only hold for assumptions made in our numerical simulations including flat area without lateral flow and no macropore flow.

    Direct measurement of unsaturated conductivity including hydraulic nonequilibrium and hysteresis (26)

    Content: The unsaturated hydraulic conductivity function is the dominant material property for modeling soil water dynamics. Because it is difficult to measure directly, it is often derived from the water retention characteristic combined with a geometric model of the pore space. In this study, we developed an automated, simple multistep flux (MSF) experiment to directly measure unsaturated conductivities, K(ψm), at a number of water potentials, ψm, using the experimental setup of classical multistep outflow (MSO) experiments. In contrast to the MSO experiment, the MSF experiment measures the conductivity directly at a spatially constant water potential assuming macroscopically homogeneous materials. Additionally, the proposed method reveals the hysteresis of K(ψm) with respect to increasing and decreasing water potentials as well as the temporal dynamics of K(ψm) during transient-flow conditions. This temporal behavior is explained by the dynamics of fluid configurations at the pore scale during drainage and imbibition leading to hydraulic nonequilibrium. It may provoke a systematic underestimation of hydraulic conductivity using inverse optimization of K(ψm) based on classical MSO experiments. The new approach will improve the determination of K(ψm) and it provides an experimental tool to quantify the effects of hydraulic nonequilibrium under transient conditions.
