Achieving the performance potential of an Exascale machine depends on realizing both operational efficiency and scalability in high performance computing applications. This requirement has motivated the emergence of several new programming models which emphasize fine and medium grain task parallelism in order to address the aggravating effects of asynchrony at scale. The performance modeling of...

Personalization and adaptivity of the Web as we know of today is often “closed” within a particular web-based system. As a result there are only a few “personalized islands” within the whole Web. Spreading the personalization to the whole Web either via an enhanced proxy server or using an agent residing on a client-side brings a challenge how to determine metadata within an open corpus Web dom...

[1] Monitoring of atmospheric methane (CH4) concentrations from space‐based instruments such as the Scanning Imaging Absorption Spectrometer for Atmospheric Chartography (SCIAMACHY) and the Greenhouse Gases Observing Satellite (GOSAT) relies on observations of sunlight backscattered to space by the Earth’s surface and atmosphere. Retrieval biases occur due to unaccounted scattering effects by a...

in this paper i develop a proxy means tests (pmt) model and examine several targeting lines based on 2008 household survey data to identify beneficiaries for a targeting subsidy scheme in iran. based on the findings of this study, setting a cut-off percentile of 40% is expected to provide compensation for almost 70 percent of the poorest households. this will result in the highest accuracy main...

We present a methodology for promoting situational awareness of an enterprise network using only network artifacts discernible from network protocol logs. We utilized latent Dirichlet allocation (LDA) over two corpora, the first composed of search queries and the second composed of external domain names issued by enterprise users through the network proxy of a mid-sized enterprise network. We n...

We identify structural vector autoregressive (SVAR) models by combining sign restrictions with information in external instruments and proxy variables. We incorporate the proxy variables by augmenting the SVAR with equations that relate them to the structural shocks. Our modeling framework allows to simultaneously identify different shocks using either sign restrictions or an external instrumen...

Landscapes and other natural scenes are easy to photograph but difficult to model and render. We present a proxy-guided pipeline which allows for simple 3D proxy geometry to be rendered with the rich visual detail found in a suitably pre-annotated example image. This greatly simplifies the geometric modeling and texture mapping of such scenes. Our method renders at near-interactive rates and is...
