A renewed reading of Kurt Lewin’s “Kriegslandschaft” (War Landscape): Personal experience, phenomenology and concept construction

The phenomenological essay “Kriegslandschaft” (War landscape) was Lewin’s first learned endeavour after his thesis and builds on his experiences as an artillery foot soldier during WW 1. In the present paper earlier readings by Heider and Bronfenbrenner are reviewed with a view to nuclei of phenomenological concepts, such as i.a. boundary, direction and zone, later to be developed in Lewin’s writi

Some paradoxes associated with a recent sum rule in scattering theory

This paper reports on some peculiarities associated with a recently published summation rule for scattering of electromagnetic waves. The summation rule states that the extinction cross section integrated over all frequencies is equal to the low-frequency response of the target. Although the summation rule is intriguing by itself, it becomes even more paradoxical when a static conductivity model o

Dynamic Scheduling and Control-Quality Optimization of Self-Triggered Control Applications

Time-triggered periodic control implementations are over provisioned for many execution scenarios in which the states of the controlled plants are close to equilibrium. To address this inefficient use of computation resources, researchers have proposed self-triggered control approaches in which the control task computes its execution deadline at runtime based on the state and dynamical properties

Non-Gods and Gods: A Cosmontological Treatise

Incorporating the conceptual resources of the ontological argument for the existence of God into the underlying rationale of the cosmological ditto, I here present and defend a ‘cosmontological’ synthesis: an a posteriori argument for the existence of an all-perfect GOD: a being who, in virtue of being whatever it is better to be than not to be, is that than which a greater cannot be thought. Cent

Engineering Saccharomyces cerevisiae for mixed-sugar fermentation

Efficient fermentation of all the monomeric sugars derived from lignocellulose is crucial to increase the economy of bioethanol production, since they can account for a considerable fraction of the fermentable sugars in the raw material. This thesis describes the engineering of Saccharomyces cerevisiae strains for improved xylose, galactose and/or arabinose utilization. S. cerevisiae is the prefer

R-hadron Searches and Charged Pion Spectra at High Transverse Momentum in Proton-Proton Collisions at the LHC using the ALICE Detector

With the start-up of the Large Hadron Collider (LHC), a new energy regime has opened up. The Standard Model (SM) can be ``rediscovered'' and new theories can be tested. ALICE, the dedicated heavy-ion experiment at LHC, will also record proton-proton (pp) collisions. Even though the main goal of the ALICE proton program is to provide the baseline measurements for interpreting the heavy-ion data,
