CO2 emissions in relation to street-network configuration and city size

Nahid Mohajeri Pour Rayeni

The street-network efficiency of tens of British cities in relation to transport fuel consumption and CO2 emissions are analyzed. The results show a strong linear positive correlation between length entropy and average street length, and a negative correla ...

Experimental Study on Wave Propagation Across a Rock Joint with Rough Surface

Xin Chen, Jian Zhao, Yang Zou

Joints are an important mechanical feature of rock masses. Their effect on wave propagation is significant in characterizing dynamic behaviors of discontinuous rock masses. An experimental study on wave propagation across artificial rock joint was carried ...

Ramsey-Type Results For Semi-Algebraic Relations

János Pach

A k-ary semi-algebraic relation E on R-d is a subset of R-kd, the set of k-tuples of points in R-d, which is determined by a finite number of polynomial inequalities in kd real variables. The description complexity of such a relation is at most t if d, k < ...

Strength of glass determined by the relation of the critical flaw to the fracture mirror

Jean-Paul Lebet, Maria Lindqvist

Tensile strength of structural glass elements is highly influenced by flaws. For this paper, the study concentrates on the fracture origin i.e. the critical flaw, situated at the edge of a glass element. In the current study the influence of two different ...

Reversible Sesqui-Pushout Rewriting, Graph Transformation

Sandro Stucki

The paper proposes a variant of sesqui-pushout rewriting (SqPO) that allows one to develop the theory of nested application conditions (NACs) for arbitrary rule spans; this is a considerable generalisation compared with existing results for NACs, which onl ...

SPBC: Leveraging the Characteristics of MPI HPC Applications for Scalable Checkpointing

André Schiper, Thomas Ropars

The high failure rate expected for future supercomputers requires the design of new fault tolerant solutions. Most checkpointing protocols are designed to work with any message-passing application but suffer from scalability issues at extreme scale. We tak ...

Linear Function Computation in Networks: Duality and Constant Gap Results

Michael Christoph Gastpar

In linear function computation, multiple source nodes communicate across a relay network to a single destination whose goal is to recover linear functions of the original source data. When the relay network is a linear deterministic network, a duality rela ...

Ramsey-type results for semi-algebraic relations

János Pach

A k-ary semi-algebraic relation E on R^d is a subset of R^{kd}, the set of k-tuples of points in R^d, which is determined by a finite number of polynomial equations and inequalities in kd real variables. The description complexity of such a relation is at ...

Discussion of three definitions of spatial justice in the writing of Jacques Lévy

Ana Moura Bastos de Fernandes Póvoas

This text address the challenge of answering to two inseparable question: What is a just territory ? and What can we do to approach more just territories? The first section of this text explores three approaches of spatial justice as deployed by Jacques Lé ...
