A variety of policies to encourage carpooling in high-occupancy vehicle (HOV) lanes have been adopted by state and local governments in the US. These policies can either increase or decrease total congestion depending on whether congestion relief in mainline lanes outweighs increased HOV lane congestion. We estimate congestion cost functions for mainline and HOV lanes in Los Angeles and find co...

Home-based care of patients is increasing in importance in many societies, particularly where health facilities are overwhelmed by human immune deficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) and patients are returned to their homes to be cared for or to await death. Care is mostly provided by close family members who have no formal training in health care, though in some cases t...

Pierre-Gerlier Forest has put forward the case that we are on the brink of a revolution in health policy that will be the result of the interplay of five factors. I would not challenge any of them but would emphasize the need to address socio-economic health inequalities, which have the potential to become a major cost driver in a time of growing economic inequality. To Dr. Forest’s list, I wou...

A many-to-many k-disjoint path cover of a graph joining two disjoint vertex subsets S and T of equal size k is a set of k vertex-disjoint paths between S and T that altogether cover every vertex of the graph. It is classified as paired if each source in S is required to be paired with a specific sink in T , or unpaired otherwise. In this paper, we develop Ore-type sufficient conditions for the ...

This paper aims to introduce the issues related to the syntactic alignment of a dependency-based multilingual parallel treebank, ParTUT. Our approach to the task starts from a lexical mapping and then attempts to expand it using dependency relations. In developing the system, however, we realized that the only dependency relations between the individual nodes were not sufficient to overcome som...

This work presents a grapheme-based approach of English-to-Chinese (E2C) transliteration, which consists of many-to-many (M2M) alignment and conditional random fields (CRF) using accessor variety (AV) as an additional feature to approximate local context of source graphemes. Experiment results show that the AV of a given English named entity generally improves effectiveness of E2C transliteration.

The functioning of a multimodal integration system requires metadata, such as ontologies, that describe media resources and media components. Such metadata are generally application and domain dependent, which causes difficulties when media need to be shared across domains. Thus, there is a need for a mechanism that can relate the key terms and/or media components in data from different sources...

Learning Decompositional Shape Models from Examples Alex Levinshtein Master of Science Graduate Department of Computer Science University of Toronto 2005 We present an algorithm for automatically constructing a decompositional shape model from examples. Unlike current approaches to structural model acquisition, in which one-to-one correspondences among appearance-based features are used to cons...

Besides lectures of theoretical foundations, contemporary teaching and learning concepts for first semester students consider more and more practically motivated courses. In this context, a new first-year student introduction course in practical engineering is established in the first semester curriculum of Electrical Engineering at RWTH Aachen University, Germany. Based on a threefold learning...
