Atlas Vernaculi: An Operational Classification for the Representation of Vernacular Architecture

Poster presented at the ENAC Research Day EPFL, CH, 08.09.2025 The primary aim of this “atlas” is to offer a systematic “anatomy” of the architectural book and its representation of vernacular architecture. A consistent analytical framework is applied to all the studied works, ensuring a methodical and comparative examination. The books selected are shown in scale with respect to one another (1:2 scale), and their content are sorted according to the representation tools and types of drawing used: text, pho

Ensuring Stability in Bilinear Structured State-Space Models via IQCs: A Free Parameterisation Approach

Recently, a novel class of Recurrent Neural Networks (RNNs) known as Structured State-space Models (SSMs) has emerged, leveraging dynamical system properties. While most SSM architectures use linear time-invariant systems as the recurrent unit, bilinear systems offer a more expressive alternative. Although existing studies impose structural restrictions on the bilinear systems, stability is not guaranteed, potentially leading to unstable or ill-posed training. This paper introduces a generic bilinear system

Information exchanges for the diffusion of energy technologies: the role of trust, frequency of interaction and proximity

The diffusion of renewable energy technologies in society is relevant in advancing the energy transition. Information exchange among the members of a social system is key to influencing the adoption-decision of innovations. Although multiple studies have identified proximity effects– the influence of close people on an individual’s behaviour – as relevant for the diffusion of energy technologies, few have focused on understanding the characteristics of the information exchange situations that affect adoptio

Provision of housing services within planetary limits: A methodological framework for the urban circular economy

The provision of decent housing for all is a core sustainable development goal (SDG) and a fundamental human right. However, the construction sector is the world's largest consumer of raw materials, and 40% of global CO2 emissions are attributed to housing and construction. The challenge of providing decarbonised and decent housing differs per urbanisation context. In rapidly developing cities, there is the question of how to build decent, affordable housing that meets human needs without locking the city i

Aesthetics – as a dimension of society and a component of spatial theory

The title of this paper suggests three things. First, that society’s issues are multidimensional i.e. society being a multidimensional system in a way that each dimension undergo the totality of society’s. These dimensions hold together social systems of various kinds and it is mistaken for a researcher to privilege any particular dimension (biological over cultural, or economic over political). Second, aesthetic, as the realm of cognitive and subjective, is one of society’s dimensions. This allows us, for

The energy transition – an integrative analysis

The ongoing energy transition is seen as a key component for the transition towards a more sustainable society. An important component in the move towards a sustainable energy system is the transition from a mainly centralized, fossil-fuel system to a more localized, renewable one. This transition, however, requires not only the development of new energy technologies but also radical, systemic shifts in deeply held values and beliefs, in patterns of social behavior, and in governance regimes. Thereby the ec

The Impact of Liars on Reputation in Social Networks

Jean-Yves Le Boudec

We consider a closed social network with a certain proportion of liars who are trying to influence their peers reputation about some subject. Each persons reputation about this subject is based on both own direct experience and second hand information from their peers which cannot be verified. Given certain assumptions on when people believe or do not believe second hand information, we investigate the liars impact on their peers reputation about the subject. We present a mathematical model for this sit

Motility: Mobility as capital

Vincent Kaufmann

Social and territorial structures form intricate relations that transcend a social stratification or spatial focus. Territorial features and geographic displacements are structuring principles for society, as societal features and social change effect the structure and use of territory. Based on our examination of the conceptual and theoretical links between spatial and social mobility, we propose a concept that represents a new form of inequality. Termed 'motility', this construct describes the potential a

Virtual Round Table on ten leading questions for network research

The following discussion is an edited summary of the public debate started during the conference "Growing Networks and Graphs in Statistical Physics, Finance, Biology and Social Systems" held in Rome in September 2003. Drafts documents were circulated electronically among experts in the field and additions and follow-up to the original discussion have been included. Among the scientists participating to the discussion L. A. N. Amaral, A. Barrat, A. L. Barabasi, G. Caldarelli, P. De Los Rios, A. Erzan, B. Ka

A modular software package for the analysis of power networks and electrical drives

Jean-Jacques Simond, Alain Sapin

This paper deals with a software package for the numerical analysis in transient and steady-state modes of power electrical networks or variable speed drives with arbitrary topologies. The package is composed of a series of units, each representing a specific cell in the network : voltage supply, electrical machine, mechanical system, transmission line, circuit-breaker, phase shifting transformer, static converter with control and command organ, regulator, etc. SIMSEN is highly flexible and efficient. It is
