-In this paper, a Catmull-Rom spline based lane model which described the perspective effect of parallel lines was proposed for generic lane boundary. As Catmull-Rom spline can form arbitrary shapes by control points, it can describe a wider range of lane structures than other lane models such as straight and parabolic model. It formulates the lane detection problem in the form of determining t...

A two-port memory contains two duplicated sets of address decoders, which operate independently. Testing such memories requires the use of single-port tests as well as special two-port tests; the test strategy determines which tests have to be used. Many two-port memories have ports which are read-only or write-only; this impacts the possible tests for single-port and two-port memories, as well...

Recently, push-based delivery has attracted considerable attention as a means of disseminating information to large client populations in both wired and wireless environments. In this paper, we address the problem of ensuring the consistency and currency of client's read-only transactions in the case of updates. Our approach is based on broadcasting invalidation reports and is scalable, i.e., i...

The microphase separated morphology of a melt of a specific class of comb-coil diblock copolymers, consisting of an AB comb block and a linear homopolymer A block, is analyzed in the weak segregation limit. On increasing the length of the homopolymer A block, the systems go through a characteristic series of structural transitions. Starting from the pure comb copolymer the first series of struc...

This paper empirically compares three estimation methods—regression, calibration, and principal person— used in a household survey for post-stratification. Posttratification is important in many household surveys to adjust for nonresponse and the population undercount that esults from frame deficiencies. The correction for population undercoverage is usually achieved by adjusting estimated peop...
