We analyze the convergence behavior of iteratively decoded coupled LDPC codes from a complexity point of view. It can be observed that the thresholds of coupled regular LDPC codes approach capacity as the node degrees and the number L of coupled blocks tend to infinity. The absence of degree two variable nodes in these capacity achieving ensembles implies for any fixed L a doubly exponential decre

This thesis consists of experimental studies of the electronic of electronic structure of the transition metals Au and Pt, and the transition metal complexes, FeIn, PtLi, and AuLi in silicon. Fourier transform infrared spectroscopy, photoconductivity, uniaxial stress- and Zeeman spectroscopy are employed. The excitation spectrum of the FeIn pair in silicon is observed for the first time. Two sets
Although political governance guides education and research, there are options for researchers, educators and curators to act in the spirit of academic freedom. The deontological ethical guidelines stabilize the archaeological establishment no matter what kind of work. The utilitarian dimensions within archaeological research and higher education open up for critical thinking.Twisting and turning,
This chapter focuses on the cognitive and emotional mechanisms of understanding. We propose that understanding consists in seeing or, more generally, experiencing a pattern. Patterns can be experienced by all sensory modalities and in abstract thinking, but here the focus is primarily on the visual modality. We discuss how understanding by experiencing patterns can be achieved in learning process
