Broken Roads and Broken Laws: How Infrastructure and Law Enforcement Shape Amazonian Deforestation Frontiers
(2020-06-29)Deforestation of tropical rainforests contributes significantly to global climate change and accelerated biodiversity loss. To mitigate these impacts, the goal of drastically reducing tropical deforestation has been a ... -
Ripening-delaying peptides and their applicability to steer quality development of climacteric fruits
(2020-06-24)Processes extending the shelf-life of climacteric fruits play an important role in increasing sustainability of global food supply. As consequence of uncontrolled ripening process, significant losses in quantity and quality ... -
Flächenhafte Deformationsanalysen mit terrestrischen und Nahbereichslaserscannern: eine Gegenüberstellung anhand von Beispielen
(2014)Dieser Beitrag stellt einen Überblick über den Ablauf einer flächenhaften Deformationsanalyse basierend auf terrestrischen Laserscannern (TLS) dar, wobei speziell auf die Datenerfassung, Vorverarbeitung und Auswertung ... -
Magnetic Field Sensor Calibration for Attitude Determination
(2014-05-29)The presented work aims to give an overview of different calibration methods for magnetic field sensors, which are used for attitude determination. These methods are applicable in the field without any additional equipment. ... -
Aiming at self-calibration of terrestrial laser scanners using only one single object and one single scan
(2014-12-05)When using terrestrial laser scanners for high quality analyses, calibrating the laser scanner is crucial due to unavoidable misconstruction of the instrument leading to systematic errors. Consequently, the development of ... -
Biased and unbiased estimates based on laser scans of surfaces with unknown deformations
(2014-10-02)The estimates based on laser scans of surfaces with unknown deformations are biased and not reproducible when changing the scanning geometry. While the existence of a bias is only disadvantageous at some applications, ... -
High-Precision Surface Inspection: Uncertainty Evaluation within an Accuracy Range of 15μm with Triangulation-based Laser Line Scanners
(2014-01-02)Triangulation-based range sensors, e.g. laser line scanners, are used for high-precision geometrical acquisition of free-form surfaces, for reverse engineering tasks or quality management. In contrast to classical tactile ... -
Automatic optimization of height network configurations for detection of surface deformations
(2013-05-18)Levellings are performed to observe height changes of different epochs at discrete surveying points. A reliable estimation of surface deformations by a bivariate polynomial needs a sufficient configuration of the underlying ... -
Optimization of point grids in regional satellite gravity analysis using a Bayesian approach
(2020-03-25)The subject of this thesis is the global and regional gravity field determination from GOCE data using the short arc approach. The focus is on the extension of the regional method regarding an adaption of the model resolution ... -
Influences on the activity and lying behavior of lactating dairy cows with particular attention to lameness
(2020-03-19)Lameness, which is usually the cause of a painful claw disease, continues to be the third most common reason for culling on dairy-producing farms in Germany. Claw diseases are not only painful, affecting both health and ... -
Regulation of branched-chain amino acid metabolism in major metabolic tissues of dairy cows during late pregnancy and early lactation
(2020-04-01)For dairy cows, the transition from late pregnancy to early lactation is characterized by dramatic changes in endocrine status, nutrient utilization as well as tissue metabolism. Specific metabolic processes, e.g., in ... -
Genetic analyses of piglet survival and postnatal growth
(2020-03-20)Piglet survival determines the success of piglet production. Decreased piglet survivability raises animal welfare concerns and increasing litter sizes intensified this situation. In the recent work, the prospects to select ... -
Interactive tillage & crop residue management effects on soil properties, crop nutrient uptake & yield in different weathered soils of West Africa: measurements, modelling & scenario simulations
(2020-04-22)Sustainable crop production intensification in West Africa is hampered by constraints such as soil degradation, mainly due to excessive mining of soil nutrients, topsoil loss by surface runoff, and climatic factors like ... -
Spatio-temporal landscape transformations in Southern Chile and its implications on ecosystem services supply and beneficiaries
(2020-03-10)Human-induced global change has driven drastic modifications of ecosystems that could lead to unexpected and unprecedented transformations in the present and future decades. Current systems modifications increased the need ... -
Changes of inner teat morphology caused by the milking process and by incomplete milking during dry-off as assessed by innovative technologies
(2020-03-03)In dairy farming, the timing of the lactation cycle and the way of milk removal differ considerably from the natural conditions. Ensuring good health and wellbeing of farm animals is of great interest from both an economic ... -
Automatische, hochaufgelöste 3D-Phänotypisierung von Trauben und Beeren der Weinrebe unter Feldbedingungen
(2020-03-03)Pilzwiderstandsfähige Sorten (PIWI) sind eine der Innovationen im Weinbau. Das Projekt Novel Viticulture Systems for sustainable production and products (NoViSys) kombiniert die PIWIs zur Effizienzsteigerung ... -
Studies on the effect of exogenous amino acid application on nematodes
(2020-03-02)Plant parasitic nematodes are considered as key pathogens in agricultural crop production. They cause substantial yield losses in numerous crops and across all climatic regions worldwide. Antagonistic effects on various ... -
Use of Black Soldier Fly (Hermetia illucens) in bioconversion and feed production
(2020-02-20)Population and economic growth, rapid urbanization and shifts in dietary preferences towards consuming more animal-derived products are some of the major challenges facing sub-Saharan Africa (SSA) today. Consequently, large ... -
Food Security Monitoring for Developing Countries in the Age of Big Data
(2020-02-10)Approximately 817 million people are currently estimated to be undernourished and 85 million people across 46 countries are estimated to be in need of food emergency assistance over the course of 2019. Conflict, migration ... -
Active 3D Reconstruction for Mobile Robots
(2020-01-13)Mapping the environment with the purpose of building a 3D model that represents it, is traditionally achieved by trained personnel, using measuring equipment such as cameras or terrestrial laser scanners. This process is ...
