Low-Cost and open-source solutions for automated image orientation --- a critical overview

Abstract: The recent developments in automated image processing for 3D reconstruction purposes have led to the diffusion of low-cost and open-source solutions which can be nowadays used by everyone to produce 3D models. The level of automation is so high that many solutions are black-boxes with poor repeatability and low reliability. The article presents an investigation of automated image orientation packages in order to clarify potentialities and performances when dealing with large and complex datasets.

A review of occupant control on natural ventilation

Abstract: According to IPCC (Intergovernmental Panel on Climate Change), the largest use of energy in commercial buildings is space heating in colder climates and air conditioning in hot climates. In Europe, the Directive on the energy performance of buildings EPBD (European Energy Performance of Buildings Directive) [1] provides a framework for national building performance regulations and calculation procedures. However, there are often large discrepancies between calculated and measured energy performance of buildings. One main reason is the behaviour of occupants, which is often not reflected in calculation models. This paper presents a literature review of various parameters influencing the effectiveness of occupant controlled natural ventilation. Additionally possibilities to implement these influences into calculation procedures/building simulation and adaptive thermal comfort evaluation are discussed.

Distance as asset? Knowledge collaboration in hybrid virtual communities

Abstract: This article takes issue with the reification of proximity in the current debates about the geographies of knowledge production. It aims at developing a more differentiated view on the spatialities of learning by focussing on knowledge practices in which neither physical nor relational proximity are available. More specifically, the article explores on the basis of a ‘netnographic approach’ interactive knowledge collaboration in nine ‘hybrid virtual communities’ that reflect a broad spectrum of organizational set-ups from firm hosted over firm related to independent communities. Our empirical analysis reveals that hybrid virtual communities even in the absence of physical or relational proximity are able to produce economically useful knowledge; that despite the low importance of proximity the physical and material conditions play a crucial role for knowledge collaboration in hybrid virtual communities; and that hybrid virtual communities afford unique technical opportunities and social dynamics that foster learning processes unattainable in face-to-face contexts.
