Abstract

The speed of sound in metallic glasses and the permittivity of dielectric alumina layers show the typical low-temperature behavior of amorphous solids. Acoustic measurements from a few kHz to GHz show the influence of the conduction electrons in a massive bulk metallic glass. Measurements of the permittivity at a few kHz surprisingly show an influence of the electrons on the properties of an insulating layer.

Abstract

Curable nanocomposites were developed to fabricate fused silica glass. During a thermal debinding and sintering step a transparent fused silica glass is received. These nanocomposites can be structured using stereolithography or replicative processes. PMMA prepolymers were developed which can be structured using lithography in a few seconds. PFPEs were established as a stereolithography material.

Abstract

AlSi12-based metal matrix composites using metallic glass Ni??Nb??Ta?? as reinforcement were produced via gas pressure melt infiltration technique. Comprehensive investigations were performed to determine the composite´s microstructural, mechanical and thermal properties as well as damage mechanisms. The results contribute to a better understanding on the material´s processing-structure-property relations.

Abstract

Monitoring of vegetation structure and functioning is critical to modeling terrestrial ecosystems and energy cycles. In particular, leaf area index (LAI) is an important structural property of vegetation used in many land surface vegetation, climate, and crop production models. Canopy structure (LAI, fCover, plant height, and biomass) and biochemical parameters (leaf pigmentation and water content) directly influence the radiative transfer process of sunlight in vegetation, determining the amount of radiation measured by passive sensors in the visible and infrared portions of the electromagnetic spectrum. Optical remote sensing (RS) methods build relationships exploiting in situ measurements and/or as outputs of physical canopy radiative transfer models. The increased availability of passive (radar and LiDAR) RS data has fostered their use in many applications for the analysis of land surface properties and processes, thanks also to their insensitivity to weather conditions and the capability to exploit rich structural and textural information. Data fusion and multi-sensor integration techniques are pressing topics to fully exploit the information conveyed by both optical and microwave bands.

Abstract

Quantitative land remote sensing has recently advanced dramatically, particularly in China. It has been largely driven by vast governmental investment, the availability of a huge amount of Chinese satellite data, geospatial information requirements for addressing pressing environmental issues and other societal benefits. Many individuals have also fostered and made great contributions to its development, and Prof. Xiaowen Li was one of these leading figures. This book is published in memory of Prof. Li. The papers collected in this book cover topics from surface reflectance simulation, inversion algorithm and estimation of variables, to applications in optical, thermal, Lidar and microwave remote sensing. The wide range of variables include directional reflectance, chlorophyll fluorescence, aerosol optical depth, incident solar radiation, albedo, surface temperature, upward longwave radiation, leaf area index, fractional vegetation cover, forest biomass, precipitation, evapotranspiration, freeze/thaw snow cover, vegetation productivity, phenology and biodiversity indicators. They clearly reflect the current level of research in this area. This book constitutes an excellent reference suitable for upper-level undergraduate students, graduate students and professionals in remote sensing.
