The impressive results of the 2007 DARPA Urban Challenge showed that fully autonomous vehicles are technologically feasible with current intelligent vehicle hardware. It is natural to ask how current transportation infrastructure can be improved when most vehicles are driven autonomously in the future. Dresner and Stone proposed a new intersection control mechanism called Autonomous Intersectio...
The DARPA Urban Challenge required robotic vehicles to travel more than 90 km through an urban environment without human intervention and included situations such as stop intersections, traffic merges, parking, and roadblocks. Team VictorTango separated the problem into three parts: base vehicle, perception, and planning. A Ford Escape outfitted with a custom drive-by-wire system and computers ...
Analysis of the transcriptome of the kleptoplastic sea slug, Elysia chlorotica, has revealed the presence of at least 101 chloroplast-encoded gene sequences and 111 transcripts matching 52 nuclear-encoded genes from the chloroplast donor, Vaucheria litorea. These data clearly show that the symbiotic chloroplasts are translationally active and, of even more interest, that a variety of functional...
Stigmatized organizations are generally assumed to face a variety of unique operational challenges. This paper examines the survival stigmatized in light such Specifically, we investigate how patterns opposition and support from multiple external stakeholders audiences affect organizational within context abortion provision United States. We use fuzzy-set qualitative comparative analysis (fsQCA...
While the discussion on the integrity of data obtained from Webdelivered experiments is mainly about issues of method and control (Mehler, 1999; McGraw et al., 2000; Auditory, 2007), this comment stresses the potential that Webbased experiments might have for studies in music perception. It is argued that, due to some important advances in technology, Web-based experiments have become a reliabl...
Sacoglossan sea slugs are the only metazoans known to perform functional kleptoplasty, the sequestration and retention of functional chloroplasts within their digestive gland cells. Remarkably, a few species with this ability can survive starvation periods of 3-12 months likely due to their stolen chloroplasts. There are no reports of kleptoplast transfer from mother slug to either eggs or juve...
The Defense Advanced Research Project Agency’s (DARPA) Urban Challenge, a contest that pitted robots against each other for 6 h without human intervention, was aimed at advancing the state-of-the-art in research for perception, planning, sensors, and situational awareness with the goal of military application. The event was a success, gaining national media attention for DARPA and robotics; but...
We evaluate and partially challenge the household leverage view of Great Recession. In data, employment consumption declined more in U.S. states where debt more. study a model monetary union composed many regions which liquidity constraints shape response to changes debt. estimate with Bayesian methods combining state aggregate data. Changes credit explain 40% differential rise fall across stat...
This paper presents a vision-based color segmentation algorithm suitable for urban environments that separates an image into areas of drivable and non-drivable terrain. Assuming that a part of the image is known to be drivable terrain, other parts of the image are classified by comparing the Euclidean distance of each pixel’s color to the mean colors of the drivable area in real-time. Moving th...
Twelve species of Dibrachys Förster are studied from China, of which four new species, Dibrachys golmudica Jiao & Xiao, sp. n., Dibrachys kunmingica Jiao & Xiao, sp. n., Dibrachys liaoi Jiao & Xiao, sp. n. and Dibrachys qinghaiensis Jiao & Xiao, sp. n., and four newly recorded species, Dibrachys braconidis (Ferrière & Faure), Dibrachys confusus (Girault), Dibrachys hians Bouček and Dibrachys ma...
