In this paper we propose an approach for global vehicle localization that combines visual odometry with map information from OpenStreetMaps to provide robust and accurate estimates for the vehicle's position. The main contribution of this work comes from the incorporation of the map data as an additional cue into the observation model of a Monte Carlo(More)
Instrumental Variables are a popular way to identify the direct causal effect of a random variable X on a variable Y. Often no single instrumental variable exists, although it is still possible to find a set of generalized instrumental variables (GIVs) and identify the causal effect of all these variables at once. Till now it was not known how to find GIVs(More)
Ancestral graphs (AGs) are graphical causal models that can represent uncertainty about the presence of latent confounders, and can be inferred from data. Here, we present an algo-rithmic framework for efficiently testing, constructing , and enumerating m-separators in AGs. Moreover, we present a new constructive criterion for covariate adjustment in(More)
Instrumental variables (IVs) are widely used to identify causal effects. For this purpose IVs have to be exogenous, i.e., causally unrelated to all variables in the model except the explanatory variable X. It can be hard to find such variables. A generalized IV method has been proposed that only requires exogeneity conditional on a set of covari-ates. This(More)
Description A port of the web-based software 'DAGitty', available at <http://dagitty.net>, for analyzing structural causal models (also known as directed acyclic graphs or DAGs). This package computes covariate adjustment sets for estimating causal effects, enumerates instrumental variables, derives testable implications (d-separation and vanishing(More)
18 middle aged patients with primary hypertension stage I were treated with 75-100 mg Obsidan/d over a period of 6 months. After treatment a significant decrease of eicosapentaenoic acid was shown. This result is important because eicosapentaenoic acid belongs to omega-3-fatty acids, precursors of eicosanoids. They are playing a vasoprotective role and(More)
The influence of humoral and secretory antibodies as well as cell supplements on Nippostrongylus brasiliensis was tested in vitro. Adult Sprague-Dawley-rats approximately 12 weeks of age were used in these experiments. For the in vitro tests the following culture media were used: 25% chicken-embryo-extract, sodium casein, pig liver extract and rat serum for(More)
The behavior of the IFT serum titer in 80 guinea-pigs, experimentally infected with Trichinella spiralis, was tested before and after treatment with mebendazole for 6 months. For 14 consecutive days each animal was drenched with 40 mg mebendazole/kg bw on the 25th, 35th and 45th day after infection. After the 2 weeks therapy, living trichinella larvae were(More)
