Reducing the environmental impact of distribution centres: Designing green-enveloped biobased alternatives to compare with reference steel and concrete designs

The climate emergency calls for a global shift towards a low-carbon economy, to preserve natural resources and biodiversity, while limiting global warming and its consequences. This project focuses on the impact of distribution centres, intended for the storage of commercial goods. Warehouses are characterised by large flexible spaces and simple...

The density theorem for discrete series representations restricted to lattices

This article considers the relation between the spanning properties of lattice orbits of discrete series representations and the associated lattice co-volume. The focus is on the density theorem, which provides a trichotomy characterizing the existence of cyclic vectors and separating vectors, and frames and Riesz sequences. We provide an...

On sufficient density conditions for lattice orbits of relative discrete series

This note provides new criteria on a unimodular group G and a discrete series representation (π, H_π) of formal degree d_π> 0 under which any lattice Γ ≤ G with vol(G/Γ)dπ≤1 (resp. vol(G/Γ)dπ≥1) admits g∈ H_π such that π(Γ) g is a frame (resp. Riesz sequence). The results apply to all projective discrete...

Smooth lattice orbits of nilpotent groups and strict comparison of projections

This paper provides sufficient density conditions for the existence of smooth vectors generating a frame or Riesz sequence in the lattice orbit of a square-integrable projective representation of a nilpotent Lie group. The conditions involve the product of lattice co-volume and formal dimension, and complement Balian–Low type theorems for the...

Density conditions with stabilizers for lattice orbits of Bergman kernels on bounded symmetric domains

Let π_α be a holomorphic discrete series representation of a connected semi-simple Lie group G with finite center, acting on a weighted Bergman space Aα2(Ω) on a bounded symmetric domain Ω , of formal dimension dπα>0. It is shown that if the Bergman kernel kz(α) is a cyclic vector for the restriction π_α| _Γ...

Hotel Ciganlija: Frames of impermanence in Belgrade's periphery

The island of Ada Ciganlija is a popular destination for residents of Belgrade and surrounding cities wishing to engage in leisure activities in a domesticated natural environment. The intensity of use of this territory changes every season and so does its density of residents.<br/>In this context, the proposed intervention explores the...

Narrative and frame analysis: Disentangling and refining two close relatives by means of a large infrastructural technology case

Social science literature frequently conflates the concepts "narrative" and "frame." We argue not only that using the terms interchangeably is conceptually imprecise but also that analyses based on them actually produce different kinds of knowledge. A systematic disentanglement, contrast and refinement of both concepts benefits from a...

Three Polemics on the Frame: An architecture in praise of openness, ambiguity, and contingencies

We live in frames — societal frames, cultural frames, politico-economic frames, ideological frames, and physical, therefore, architectural frames. Evidently, frames manifest as abstract concepts as easily as they assume material forms. With the endless ways in which it can manifest come also a multiplicity of agencies, ways in which the frame...

Hybrid Frame: An urban program generator for a shrinking city

The design project based in Genova develops the possibility of reconnecting an urban void to the existing urban fabric, through the implementation of an architectural and infrastructural frame which is saturated with program, so that the new connection proposed becomes also a destination for the city.

Scale, Frame and Language: Highway community center in the periphery of Rome

The periphery of Rome in its chaotic sprawl created a condition of extremes. Trough time the distinction between private and public space, between low density and high density became blurred generating a condition where different scales of space and time cross each other. This thesis develops a process where this condition of constant limit is...
