On algebraic array theories

Viktor Kuncak, Rodrigo Raya

Automatic verification of programs manipulating arrays relies on specialised decision procedures. A methodology to classify the theories handled by these procedures is introduced. It is based on decomposition theorems in the style of Feferman and Vaught. T ...

Bit-Line Computing for CNN Accelerators Co-Design in Edge AI Inference

David Atienza Alonso, Giovanni Ansaloni, Alexandre Sébastien Julien Levisse, Flavio Ponzina, Marco Antonio Rios

By supporting the access of multiple memory words at the same time, Bit-line Computing (BC) architectures allow the parallel execution of bit-wise operations in-memory. At the array periphery, arithmetic operations are then derived with little additional o ...

JET ILA full array and polychromatic operation

Paulo Giovane Paschoali Pereira Puglia

The JET ILA is an Ion Cyclotron Resonance Heating (ICRH) antenna composed of four resonant double loops (RDLs) arranged in a 2 toroidal by 2 poloidal compact array. It has been operated in a range of frequencies from 29 to 51 MHz, but mostly on half array. ...

Full key recovery side-channel attack against ephemeral SIKE on the Cortex-M4

Aymeric Genet, Novak Kaluderovic

This paper describes the first practical single-trace side-channel power analysis of SIKE. While SIKE is a post-quantum key exchange, the scheme still relies on a secret elliptic curve scalar multiplication which involves a loop of a double-and-add procedu ...

Origin of enhancement in Raman scattering from Ag-dressed carbon-nanotube antennas: experiment and modelling

Olivier Martin

The D- and G-band Raman signals from random arrays of vertically aligned, multi-walled carbon nanotubes are significantly enhanced (up to ∼14×) while the signal from the underlying Si substrate is simultaneously attenuated (up to ∼6×) when the nanotubes ar ...

Turbulent Flows within Random Arrays of Rigid and Emergent Cylinders with Varying Distribution

Mário Jorge Rodrigues Pereira Da Franca, Ana Margarida Da Costa Ricardo

The spatial distribution of emergent vegetation in rivers is frequently nonuniform. Here, spatial nonuniformity is simulated in the laboratory by varying longitudinally the stem areal number density (m). Time- and space-averaged flow variables, correspondi ...

Optical Design of Multisource High-Flux Solar Simulators

Sophia Haussener

We present a systematic approach to the design of a set of high-flux solar simulators (HFSSs) for solar thermal, thermochemical, and materials research. The generic simulator concept consists of an array of identical radiation modules arranged in concentri ...

The terms of turbulent kinetic energy budget within random arrays of emergent cylinders

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Ana Margarida Da Costa Ricardo

This article is aimed at quantifying and discussing the relative magnitude of key terms of the equation of conservation of turbulent kinetic energy (TKE) in the inter-stem space of a flow within arrays of vertical cylinders simulating plant stems of emerge ...

Large Arrays Of Inkjet-Printed Mems Microbridges On Foil

Nico de Rooij, Danick Briand, Francisco Molina Lopez

This works describes the fabrication process of an array of printed MEMS microbridges on polymeric foil, performed in only four easy steps. Each functional material was deposited exclusively by inkjet-printing technique, compatible with large-area fabricat ...

Turbulent flow within a random array of rigid, emergent stems : Laboratory characterization of the drag coefficient

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Ana Margarida Da Costa Ricardo

Within the bioengineering framework, designing a non-erodible channel is a complex fluid dynamics problem as it involves knowing the drag exerted on the boundary, the drag exerted on the plant stems and the overall friction slope. Most of the existing desi ...

Optimal polarization synthesis of arbitrary arrays with focused power pattern

Benjamin Fuchs, Benjamin Fuchs

The joint synthesis of the spatial power pattern and polarization of arbitrary arrays is addressed. Specifically, the proposed approach gives the solution to a frequently encountered problem, namely the array design (i.e., the determination of the radiatin ...

Another Glance at Double-Length Hashing

Martijn Stam, Onur Özen

We propose a novel framework for blockcipher-based double-length hash functions by extending the recent generalization presented by Stam at FSE '09 for single-call hash functions. We focus on compression functions compressing 3n bits to 2n bits that use on ...
