Non-WSSUS Vehicular Channel Characterization at 5.2 GHz - Spectral Divergence and Time-Variant Coherence Parameters

The scattering environment in vehicle-to-vehicle communication channels at 5.2 GHz changes rapidly. Hence the wide-sense stationary (WSS) uncorrelated scattering (US) assumption for the fading process is valid for short time intervals only. We characterize the spectral divergence of the local scattering function (LSF) sequence in order to assess the non-WSSUS characteristics in different scenarios

Perception verbs revisited

This paper will present some very general descriptions of language-specific conceptualization of visual perception in English and Lithuanian, and will focus on some basic structure-dependent types of meaning of the see and seem type perception verbs in English and Lithuanian. For this purpose, the hierarchical structure of the clause and the typology of perception verb complements proposed by Simo

Modelling of Microturbine systems

The paper describes the development of a dynamic model of amicroturbine system. The paper was done in close cooperation with the gas turbine manufacturer Turbec AB and the model was tuned and verified against theirmicroturbine system T100. The microturbine unit consists of a compressor and a turbine connected on a single shaft to a high-speed generator.The model includes all the main thermodynamic
