Ecological security is an important research topic, especially urban ecological security. As highly populated eco-systems, cities always have more fragile ecological environments. However, most of the research on urban ecological security in literature has focused on evaluating current or past status of the ecological environment. Very little literature has carried out simulation or prediction ...

Composite Stock Price Index (IDX) shows the movement of stock prices used by investors to determine their investment strategy. IDX is influenced macroeconomic factors such as money supply and inflation, so regression analysis relationship between variables. Based on scatterplot, known a parametric predictor variable it has linier line patterned scatterplot inflation nonparametric random semipar...

In this paper, we present an iterative Kalman smoother (IKS) for robust 3D localization and mapping, using visual and inertial measurements. Contrary to extended Kalman filter (EKF) methods, smoothing increases the convergence rate of critical parameters (e.g., IMU’s velocity and camera’s clock drift), improves the positioning accuracy during challenging conditions (e.g., scarcity of visual fea...

the acute ecotoxicity of a set of mixture samples (washing powders, wastes, fuel extracts etc.) was assessed using four acute ecotoxicity assays with aquatic organisms (daphnia magna, poecilia reticulata, artemia salina and desmodesmus subspicatus). the experimental concentration-response curves were fitted by seven two-parameter sigmoid equations using non-linear regression. the regression pe...

The aim of the present study was to validate the Glucoday continuous interstitial ambulatory glucose-monitoring device (AGD) against plasma glucose measured from arterialised venous (AV) and glucose from capillary whole blood (finger prick, FP) in non-diabetic subjects in response to an oral glucose tolerance test. Fifteen healthy overweight men (age 30-49 years, BMI 26-31 kg/m2) participated. ...

Atypical observations hidden in the data may play quite an disastrous role in a tted regression, especially when commonly used outlier detection techniques like computing leverages, Mahalanobis distances, ordinary and studentized residuals, DFFits, cross-validations { do not detect them. However (multivariate) outliers can be detected quite easily by graphical techniques , e.g. scatterplot matr...

In this extended abstract we introduce a new method for eliciting experts, prior knowledge about the similarity of the roles of features in the prediction task. The key idea is to use an interactive multidimensional-scaling-type scatterplot display of the features to elicit the similarity relationships, and then use the elicited relationships in the prior distribution of prediction parameters. ...

OBJECTIVE To assess the association between first-trimester HbA(1c) (A1C) and the risk of adverse pregnancy outcomes in type 1 diabetic pregnancies. RESEARCH DESIGN AND METHODS We identified all pregnant diabetic women in a Danish county from 1985 to 2003. A1C values from first trimester were collected, and pregnancy outcome was dichotomized as good (i.e., babies surviving the 1st month of li...
