Wearout-Aware Compiler-Directed Register Assignment for Embedded Systems

David Atienza Alonso

Although constant technology scaling has resulted in considerable benefits, smaller device dimensions, higher operating temperatures and electric fields have also contributed to faster device aging due to wearout. Not only does this result in the shortenin ...

Thermal boundary conductance of transition metals on diamond

Christian Monachon, Ludger Weber

An experimental process that was used to obtain a direct measurement of Thermal Boundary Conductance (TBC) between a diamond substrate and several transition metals, deposited by sputtering, is described. Using Time-Domain ThermoReflectance (TDTR), the cri ...

MATHICSE Technical Report : Convergence of quasi-optimal stochastic Galerkin methods for a class of PDES with random coefficients

Fabio Nobile, Lorenzo Tamellini

In this work we consider quasi-optimal versions of the Stochastic Galerkin Method for solving linear elliptic PDEs with stochastic coeffcients. In particular, we consider the case of a finite number N of random inputs and an analytic dependence of the solu ...

Influence of sample processing parameters on thermal boundary conductance value in an Al/AlN system

Christian Monachon, Ludger Weber, Mohamad Hojeij

The influence of sample processing parameters on the thermal boundary conductance (TBC) between aluminum and aluminum nitride has been investigated by transient thermoreflectance. An evaporated Al layer on the polished substrate yielded a TBC at ambient of ...

Thermal conductivity and interfacial conductance of AlN particle reinforced metal matrix composites

Andreas Mortensen, Christian Monachon, Ludger Weber, Masahiro Kida

Aluminum nitride (AlN) particle reinforced metal-matrix-composites produced by pressure infiltration are characterized in terms of their thermal conductivity. The composites are designed to cover a wide range of phase contrast between the dispersed particl ...

Thermal Modeling and Management of Liquid-Cooled 3D Stacked Architectures

David Atienza Alonso, Ayse Kivilcim Coskun

3D stacked architectures are getting increasingly attractive as they improve yield, reduce interconnect power and latency, and enable integrating layers manufactured with different technologies on the same chip. However, 3D integration results in higher te ...

In-situ testing of a heat exchanger pile

Lyesse Laloui

The behavior of a pile subjected to thermo-mechanical loadings was studied in situ with the aim of quantifying the thermal influence on the bearing capacity of heat exchanger piles. A pile situated in a building under construction was equipped with a chann ...

Convex-Based Thermal Management for 3D MPSoCs Using DVFS and Variable-Flow Liquid Cooling

Giovanni De Micheli, David Atienza Alonso, Francesco Zanini

In this work, we propose a novel online thermal management approach based on model predictive control for 3D multi-processors system on chip (MPSoCs) using microfluidic cooling. The controller uses dynamic voltage and frequency scaling (DVFS) for the compu ...

Review on the EFDA programme on tungsten materials technology and science

Nadine Baluc, Robin Schäublin, Lyubomira Veleva, Daniela Rupp

All the recent DEMO design studies for helium cooled divertors utilize tungsten materials and alloys, mainly due to their high temperature strength, good thermal conductivity, low erosion, and comparably low activation under neutron irradiation. The long-t ...
