IS THERE AN EFFECT OF MACULAR PIGMENT DENSITY ON DISCOMFORT GLARE IN INDOOR DAYLIGHT CONDITIONS?

Marilyne Andersen, Jan Wienold, Caroline Karmann, Sneha Jain

Discomfort glare from daylight can lower productivity and hinder effective use of daylight in buildings. Existing glare prediction models have limitations in accounting for the large inter-individual differences, mainly due to unknown physiological factors ...

A system design for elastically scaling transaction processing engines in virtualized servers

Anastasia Ailamaki, Angelos Christos Anadiotis, Raja Appuswamy, Hillel Avni

Online Transaction Processing (OLTP) deployments are migrating from on-premise to cloud settings in order to exploit the elasticity of cloud infrastructure which allows them to adapt to workload variations. However, cloud adaptation comes at the cost of re ...

A Minimally Intrusive Low-Memory Approach to Resilience for Existing Transient Solvers

Allan Svejstrup Nielsen

We propose a novel, minimally intrusive approach to adding fault tolerance to existing complex scientific simulation codes, used for addressing a broad range of time-dependent problems on the next generation of supercomputers. Exascale systems have the pot ...

Challenges of Memory Management on Modern NUMA Systems

Baptiste Joseph Eustache Lepers, Mohammad Dashti Rahmat Abadi

The latency of memory access times is hence non-uniform, because it depends on where the request originates and where it is destined to go. Such systems are referred to as nonuniform memory access (or NUMA). Current x86 NUMA systems are cache coherent (cal ...

Microhydration Effects on the Encapsulation of Potassium Ion by Dibenzo-18-Crown-6

Thomas Rizzo, Yoshiya Inokuchi

We have measured electronic and conformer-specific vibrational spectra of hydrated dibenzo-18-crown-6 (DB18C6) complexes with potassium ion, K+center dot DB18C6 center dot(H2O)(n) (n = 1-5), in a cold, 22-pole ion trap. We also present for comparison spect ...

Human needs as a driver for lighting design

Marilyne Andersen

Thanks to fundamental discoveries from neuroscience, biology and others, we have achieved a deeper understanding of how we interact with our environment. It is time to bring this knowledge back to architecture: we have access to the essential ingredients o ...
