Focus particles interact with the focused constituent in a sentence. The particle only presents a challenge to formalizing this relationship as while it commonly precedes the focused constituent, only can also follow it. A syntactic account of these constructions is presented that captures the unique properties of only’s distribution within the framework presented in Kayne (1998) and offers sup...

This paper describes a system for detecting and estimating the properties of multiple travel lanes in an urban road network from calibrated video imagery and laser range data acquired by a moving vehicle. The system operates in real-time in several stages on multiple processors, fusing detected road markings, obstacles, and curbs into a stable non-parametric estimate of nearby travel lanes. The...
