Minkowski space is locally the Noldus limit of Poisson process causets

A Poisson process P-lambda on R-d with causal structure inherited from the the usual Minkowski metric on R-d has a normalised discrete causal distance D-lambda (x, y) given by the height of the longest causal chain normalised by lambda(1/d)c(d). We prove t ...

Compact Microwave Cavity with Increased Magnetic Field Homogeneity

Anja Skrivervik, Anton Evgeniev Ivanov

In this study we aim at improving the homogeneity of the magnetic field inside a microwave resonator cavity designed in line with the development of a novel, high performance frequency standard. We study the effect of modified boundary conditions applied t ...

Design of Compact Air-Vias-Perforated SIW Horn Antenna With Partially Detached Broad Walls

Lei Wang

A novel substrate-integrated waveguide (SIW) horn antenna with partially detached broad walls is designed and analyzed. The conventional SIW horn antenna suffers from narrow-operating bandwidth, which mainly results from the mismatch at the horn aperture b ...

Effects of urban compactness on solar energy potential

Jean-Louis Scartezzini, Jérôme Henri Kämpf, Govinda Upadhyay, Nahid Mohajeri Pour Rayeni, Dan Assouline

Compactness is a major urban form parameter that affects the accessibility of solar energy in the built environment. Here we explore the relation between various compactness indicators and solar potential in the 16 neighbourhoods (11,418 buildings) constit ...

Sequences with Minimal Time-Frequency Uncertainty

Martin Vetterli, Yann Barbotin, Reza Parhizkar

A central problem in signal processing and communications is to design signals that are compact both in time and frequency. Heisenberg's uncertainty principle states that a given function cannot be arbitrarily compact both in time and frequency, defining a ...

Maximizing the displacement of compact planar dielectric elastomer actuators

Samuel Rosset, Herbert Shea, Oluwaseun Adelowo Araromi

We present a model and its experimental validation for the optimization of the in-plane displacement of a rigid platform mounted on a compact dielectric elastomer actuator. Unlike the situation in which the mechanical prestretch of the membrane is maintain ...
