Although regression quantiles (RQs) are increasingly becoming popular, they are still playing a second fiddle role to the ordinary least squares estimator like their robust counterparts due to the perceived complexity of the robust statistical methodology. In order to make them attractive to statistical practitioners, an endeavor to studentize robust estimators has been undertaken by some resea...

Abstract Besides information-seeking questions, there are all kinds of non-standard whose function is not to request information from the addressee, but rather convey about speaker’s epistemic or emotional state. These include rhetorical surprise incredulity etc. This paper focuses on questions (RQs), a sub-type non-canonical and presents first production experiment which has investigated them ...

This paper investigates how to reinitialize a modelbased face tracker after tracking failure. The information gathered in the original initialization is used to obtain a quick an reliable reinitialization. The color information of the model texture map is used to obtain a skin color model that is per definition adapted to the lighting, camera and the specific skin tone of the user. The search f...

The back-off methodology has been extensively developed and refined in the last 20 years and offers a systematic tool for solving the simultaneous design and control problem. Previous work has been based on linear process and control models that ensure quick determination of the optimal solution at the expense of potential loss in the accuracy due to nonlinear process characteristics. In this w...

This paper addresses the problem of self-location for a mobile robot equipped with a single camera moving in an indoor environment. The robot is provided with a twodimensional map where the position and some attributes of landmark points are stored. The proposed algorithm first determines the observation rays of vertical edges extractedfiom one image and then finds an interpretation for these r...

BACKGROUND Evidence supporting antibiotic treatment guidelines and respiratory quinolones (RQs) in community-acquired pneumonia (CAP) is limited. OBJECTIVE To study associations among guideline adherence, specific antibiotics, clinical outcomes and antibiotic costs. METHODS A retrospective cohort study in three tertiary care university teaching hospitals in Toronto, Ontario, studying CAP in...

Learning to program is hard and one major obstacle for students is getting to grips with the programming process itself: What do I do now, what are the next steps, and what end result do I want to achieve? Further complications arise as many, even simple, designs require quite a lot of code to be written that are just “stepping stones” on the path to a solution. Thus, instead of “writing the co...
