Abstract We consider an experimental system consisting of a pendulum, which is free to rotate 360 degrees, attached to a cart. The cart can move in one dimension. We study the effect of friction on the design and performance of a feedback controller, a linear quadratic regulator, that aim to stabilize the pendulum in the upright position. We show that a controller designed using a simple viscou...

This paper explores a novel framework for building regression models using association rules. The model consists of an ordered set of IF-THEN rules, where the rule consequent is the predicted value of the target attribute. The approach consist of two steps: (1) extraction of association rules, and (2) construction of the rule-based regression model. We propose a pruning scheme for redundant and...

Cocaine- and amphetamine-regulated transcript (CART) encodes a neuropeptide precursor protein that is highly abundant in cells of the hypothalamus. To date, the major research focus into the function of CART peptides has been feeding behavior. However, CART mRNA is found in other areas of the brain as well as some peripheral tissues, suggesting possible broader functions of this peptide. In thi...

Abstract Sovereign credit ratings summarize the creditworthiness of countries. These have a large influence on economy and yields at which governments can issue new debt. This paper investigates use multilayer perceptron (MLP), classification regression trees (CART), support vector machines (SVM), Naïve Bayes (NB), an ordered logit (OL) model for prediction sovereign ratings. We show that MLP i...

To analyze contemporary costs of HIV health care and the cost distribution across lines of combination antiretroviral therapy (cART). To identify variations in expenditures with patient characteristics and to identify main cost determinants. To compute cost ratios between patients with varying characteristics.Empirical data on costs are collected in Germany within a 2-year prospective observati...

Emotion is an important element in expressive speech synthesis. The paper makes the brief analysis on prosody parameters, stresses, rhythms and paralinguistic information in different emotional speech, and labels the speech with rich annotation information in multi-layers. Then, a CART model is used to do the emotional prosody generation. Unlike the traditional linear modification method, which...

As more HIV patients start combination antiretroviral therapy (cART), the emergence of drug resistance (HIVDR) is inevitable. This will have consequences for transmission HIVDR, success ART, and nature trend epidemic. We recruited a cohort 223 starting or continuing their first-line cART in Tanzania towards end stavudine era 2010. Patients were then followed one year. Of those with viral load t...

PURPOSE Cocaine- and amphetamine-regulated transcript (CART) peptide exerts several regulatory functions acting both as neurotransmitter and hormone. We recently showed that CART is expressed in various neuroendocrine tumors, including small bowel carcinoids. The main objective of the present study was to examine whether CART expression is associated with survival in patients with small bowel c...

BACKGROUND Hepatitis B virus (HBV) vaccine antibody response has been associated with reduced risk of AIDS or death. However, it is unknown whether HBV vaccine responsiveness is associated with improved immune reconstitution during treatment with combination antiretroviral therapy (cART). We evaluated the relationship between HBV vaccine response status and CD4 reconstitution on cART in the U.S...
