Scalable architecture for context-aware activity-detecting mobile recommendation systems
In this paper we describe the implementation of a mobile recommender system for leisure activities, codenamed Magitti, which was built for commercial deployment under stringent scalability requirements.

An integrated approach to qualitative model-based diagnosis
In this paper we propose a first step towards developing a more integrated multi-faceted approach to qualitative model-based reasoning.

Understanding the efficiency of social tagging systems using information theory
We analyze a social tagging site, namely del.icio.us, with information theory in order to evaluate the efficiency of this social tagging site for encoding navigation paths to information sources.

Using utility and microutility to manage resources in vehicle ad hoc networks
In this paper we describe how sources can model the potential usefulness of their information using utility functions that describe where and at what data rates the information will be…

Using utility and microutility to manage resources in vehicle ad hoc networks
We describe an approach to propagating streams of information in Vehicle Ad-Hoc Networks (VANETs) based on sources of information predicting where the information will be useful---information is pushed "based on…

Low cost, membrane-less water purification
PARC has developed a compact, low-cost purification system that reduces maintenance down-time, increases throughput, decreases power consumption, and shrinks real estate requirements.

Matching Vehicles Under Large Pose Transformations Using Approximate 3D Models and Piecewise MRF Model
We propose a robust object recognition method based on approximate 3D models that can effectively match objects under large viewpoint changes and partial occlusion.

Systematic Biological Prioritization After a Genome-Wide Association Study: an Application to Nicotine Dependence
We introduce a method for systematically prioritizing single nucleotide polymorphisms (SNPs) for further study after a GWAS. The method combines evidence across multiple domains including statistical evidence of genotype–phenotype correlation,…

Building Segmentation for Densely Built Urban Regions Using Aerial LIDAR Data
We present a novel building segmentation system for densely built areas, containing thousands of buildings per square kilometer.
