Complex topography

We thank W. Fellin from the Institute for Geotechnique and Tunnel Engineering, University of Innsbruck, Austria for the discussions concerning the pressure dependences of the internal and bed friction angles, Financial support was provided by the Deutsche Forschungsgemeinsch-aft through the project - Hu 412/33-1 Avalanche Dynamics in Complex Topography ... 

Turbulent flow in canopies on complex topography and the effects of stable stratification... 

The theory reviewed and discussed here has already found a number of practical applications, particularly in the meteorology of forests and complex topography, Chapter 5, the hydraulics of open water flows, Chapter 6, the thermal performance of spraying coolers, Chapters 1 and 3 and the mitigation of large fire danger, Chapter 8 as well as in urban air pollution, emergency preparedness and prediction of urban climate, Chapter 9. 

Dr. John Finnigan from Australian Commonwealth Scientific and Industrial Research Organization (CSIRO), Australia in his chapter extends his analysis of the eddy structure of canopy winds to include the effects of complex topography. He shows that there are special features of airflow through forests and over hills that significantly affect the weather and the ecology in these very common situations. 

The EMEP model overestimates the measurements for the territory of Slovakia, possibly due to the very complex topography. The correlation of calculated and measured concentrations decreases with altitude.

Interpolation of ground and upper air observations (objective analysis). These are the simplest methods, but the quality of their results depends critically on the spatial and temporal density of ob.servations. Results are often erroneous in areas without observations or of complex topography. 

The use of more complex systems such as ternary blends allows the functionalization of the surfaces with varies chemical functionalities. For instance a PS matrix was mixed with two block copolymers, a hydrophobic (PS-b-P5FS) and an amphiphilic polystyrene-b-poly[poly(ethylene glycol) methyl ether methacrylate] (PS-6-P(PEGMA)) copolymer [96], The chemical distribution of the resultant surface pattern implies an enrichment of the holes in the amphiphilic copolymer with an external surface mainly functionalized in the fluorinated copolymer with low surface energy (Scheme lO.lg). Other ternary blends combining incompatible copolymers and homopolymers have been reported leading to more complex topographies and chemical distributions [148],... 

As a close related compound to the chemiluminescence systems, the anthracene-9,10-endoperoxide has been used to describe the complex topography which characterises the region of crossing between the ground and excited state PESs in the 0-0 photolysis. Four eleetronic states involving different electron occupations of the aoo> < oo ... 

The successful photoresist materials benefit from dividing the roles of the resist between two components. The polymeric resin endows the necessary etch resistance, adhesion and film-forming properties whilst the sensitiser is largely responsible for the resist s sensitivity. Even so, the photoresists are being driven to their limits in terms of resolution over more and more complex topographies which makes it ever more difficult for any single resist film to meet all the requirements. 

Another consequence of a complex topography is mechanical interlocking between the adhesive and substrate. This is analogous to fastening with a hook and eye or with Velcro , where a resistance to separation is present without... 

In the condensation reaction between a trifunctional alcohol and a difunctional isocyanate, gel formation is marked by significant changes in the velocity and attenuation in the MHz region. The relaxation in the isolated monomers can be ascribed to a combination of intra- and inter-molecular processes. Intermolecular relaxation occurs in the hydrogen-bonded structure formed as a result of hydroxyl interactions. Reaction between the isocyanate and alcohol leads to the possibility of normal mode contributions to the relaxation spectrum and consequent increase in the ultrasonic attenuation. Detailed analysis of the data is difficult because of the complex topography generated by the reaction of di- and tri-functional monomers. This study does however once more illustrate the possibility of using ultrasonic techniques to monitor polymerization processes.
