    The aim of this work is to present a semi-analytical light curve modeling code which can be used for estimating physical properties of core collapse supernovae (SNe) in a quick and efficient way. To verify our code we fit light curves of Type II SNe and compare our best parameter estimates to those from hydrodynamical calculations. For this analysis we use the quasi-bolometric light curves of five different Type IIP supernovae. In each case we get appropriate results for the initial pre-supernova parameters. We conclude that this semi-analytical light curve model is useful to get approximate physical properties of Type II SNe without using time-consuming numerical hydrodynamic simulations.Comment: accepted for publication in Astronomy \& Astrophysics; corrected Fig.2, 3,

    Post Occupancy Evaluation of Sustainable Schools and Children\u27s ways of Knowing: New Directions in Teaching and Research

    Architecture is now more than ever dominated by scientific method. This paper examines what is really at stake when designing sustainable architecture. It is a methodological study and focused on science as understood in Post Occupancy Evaluation (POE) of sustainable buildings, specifically school buildings. Questions raised in this paper include the very real problem of designing for children’s comfort and education in school architecture, but also much wider issues than simply those of the design of children’s environments

    Plant ethics or an environment for the birth of a new human? An exploration in radical ethics for sustainable architecture.

    This paper critically examines literature concerned with an ethics in the multiplicity of different approaches to the design of sustainable architecture. Sustainable design theorists commonly argue for the need to perceive the world differently, to find new ways to live, to create new values to replace old: questions of ethics are implicit in such explorations

    “I enter a building, see a room, and…” Peter Zumthor writes, “in a fraction of a second I have this feeling about it” (Zumthor 2006: 13). As an immediately grasped judgment of environmental character, atmosphere has been described as a collaboration of an infinite number of multisensory factors: a non-material experience, contrasting centuries of tradition understanding architecture as material artefact experienced through the limitation of vision (Pallasmaa 2014: 20)
