Low-rank Kronecker-factored Approximate Curvature for Training Deep Neural Networks
(2022)Second-order optimization methods applied to train deep neural net- works use the curvature information of a loss function to enable much faster convergence in the number of steps than first-order methods. However, since the second-order methods need the curvature matrix and its inverse, they have a huge computational and memory overhead that negates the faster convergence in terms of time. For this reason, first-order optimization methods ...Bachelor Thesis -
Treelines in the Swiss Alps: Growth Dynamics and Forest Succession in a Changing Climate
(2017)The alpine treeline is one of the most prominent ecosystem boundaries in nature. The two ecosystems that are separated by this ecotone – the subalpine forest and the alpine tundra – provide essential ecosystem goods and services (EGS) in densely populated mountain regions like the European Alps. Ongoing global climate change with its temperature increase affects the major limiting factor of tree growth close to treeline. Moreover, mountain ...Doctoral Thesis -

Approaches to Crisis Prevention in Lean Product Development by High Performance Teams and through Risk Management
(2005)This thesis investigates crisis prevention in lean product development, focusing on high performance teams and risk management methods. Lean product development and the Munich Procedural Model (MPM) are the guiding frameworks for this thesis. From the MPM, team work and risk management are derived as important elements in crisis prevention, from lean product development, especially the notion of value is used to define basic types of ...Master Thesis -
Exploring the Potential of Blockchain and Cryptoeconomics for the Construction Industry
(2022)The construction industry needs to become more efficient and productive in order to cope with increasing housing and infrastructure demand, as well as problems associated with climate change. Digitalization is often seen as the solution for this transformative change, but so far, its anticipated impact did not materialize. The construction industry is complex and current project delivery fails to achieve the needed trusted collaboration, ...Doctoral Thesis
