Title of Dissertation: Privacy Preserving Distributed Data Mining based on Multi-objective Optimization and Algorithmic Game Theory Kamalika Das, Doctor of Philosophy, 2009 Thesis directed by: Dr. Hillol Kargupta Professor Department of Computer Science and Electrical Engineering Use of technology for data collection and analysis has seen an unprecedented growth in the last couple of decades. I...

Left ventricular (LV) epicardial pacing acutely reduces wall thickening at the pacing site. Because LV epicardial pacing also reduces transverse shear deformation, which is related to myocardial sheet shear, we hypothesized that impaired end-systolic wall thickening at the pacing site is due to reduction in myocardial sheet shear deformation, resulting in a reduced contribution of sheet shear t...

let $g$ be a finite group‎. ‎we say that $g$ has emph{spread} r if for any set of distinct non-trivial elements of $g$ $x:={x_1,ldots‎, ‎x_r}subset g^{#}$ there exists an element $yin g$ with the property that $langle x_i,yrangle=g$ for every $1leq ileq r$‎. ‎we say $g$ has emph{exact spread} $r$ if $g$ has spread $r$ but not $r+1$‎. ‎the spreads of finite simple groups and their decorations ha...

Using a low-temperature conductive-tip atomic force microscope in cross-section geometry we have characterized the local transport properties of the metallic electron gas that forms at the interface between LaAlO3 and SrTiO3. At low temperature, we find that the carriers do not spread away from the interface but are confined within approximately 10 nm, just like at room temperature. Simulations...

This paper examines the implications of utilizing decision support systems (DSS) in the public sector based on a DSS developed and implemented for a community mental health system. The DSS includes a multiple objective (goal programming) allocation model and encompasses a multiple party decision process. The experiences and insights acquired during the development and implementation are relevan...

This paper highlights the capabilities and significance of a new e-learning tool developed at Informatics and Process Control research group. The main objective is to facilitate the students in simulating and experimenting different subject concepts in a new e-learning environment. It also aims at teaching students to make use of simple, economical and easily accessible spreadsheet tool like MS...

Chitosan/silk fibroin (CS/SF) blend films were prepared and evaluated for feasibility of using the films as biomaterial for skin tissue engineering application. Fourier transform infrared spectroscopy and differential scanning calorimetry analysis indicated chemical interaction between chitosan and fibroin. Chitosan enhanced β-sheet conformation of fibroin and resulted in shifting of thermal de...

MASTER, the Muttenzer Assistant for Simulation Tasks with Expert Reasoning, is a hybrid simulation environment under development at the Basle Institute of Technology. MASTER should allow experienced, occasional or even unexperienced user to perform efficient simulation studies. In order to achieve this aim its architecture combines ’in parallel’ a powerful general-purpose simulation language (S...

The ratio of observed-to-expected deaths is considered a measure of hospital quality and for this reason will soon become a basis for payment. However, there are drivers of that metric more potent than quality: most important are medical documentation and patient acuity. If hositals underdocument and therefore do not capture the full "expected mortality" they may be tempted to lower their obser...
