Stratification and weighting via the propensity score in estimation of causal treatment effects: A comparative study
 Statistics in Medicine
, 2004
"... Estimation of treatment effects with causal interpretation from observational data is complicated because exposure to treatment may be confounded with subject characteristics. The propensity score, the probability of treatment exposure conditional on covariates, is the basis for two approaches to ad ..."

Practical techniques for language design and prototyping
 In Dagstuhl Seminar 05081 on Foundations of Global Computing. February 20 – 25, 2005. Schloss Dagstuhl
, 2005
"... Abstract. Global computing involves the interplay of a vast variety of languages, but practially useful foundations for language specification and prototyping at the semantic level are lacking. In this paper we present a systematic approach consisting of three techniques: 1. A generic calculus of e ..."

On the Tradeoff between Effectiveness and Scalability of MeasurementBased Admission Control
, 1999
"... The key problem to be solved in MBAC is to efficiently utilise the information provided by the sources and measured by the network. There is a direct relationship between the amount of information available and the resulting effectiveness of the admission algorithm. In this paper we analyse the trad ..."

Lump Circuits Elements Values Extraction of Acoustic Transducers Using Impedance Measurement Approach
"... Abstract: Acoustic transducers are the popular elements for sonar array. The transducer of the simplify electrical equivalent circuit is discussed, and a impedance measurement system is developed to estimate the elements value of transducer’s lump circuit model at or near resonance. For practial ap ..."

How to Uniformly Specify Program Analysis and Transformation with Graph Rewrite Systems
 Compiler Construction (CC
, 1996
"... . Implementing program optimizers is a task which swallows an enourmous amount of manpower. To reduce development time a simple and practial specification method is highly desirable. Such a method should comprise both program analysis and transformation. However, although several frameworks for pro ..."

Generalizations of the floor and ceiling functions using the SternBrocot tree
"... We consider a fundamental number theoretic problem where practial applications abound. We decompose any rational number a b in c ratios as evenly as possible while maintaining the sum of numerators and the sum of denominators. The minimum � � a b c and maximum � � a of the ratios b c give rational ..."

Transforming Ordered Constraint Hierarchies into Ordinary Constraint Systems
 In Jampel et al
, 1996
"... In this paper, we propose ordered constraint hierarchies and a nontrivial error function to model and solve overconstrained realworld problems adequatly. We substantiate our proposition by an example. Then we present a new method to transform constraint hierarchies into equivalent ordinary constr ..."

constraint systems. For practial applications, we present a modified algorithm based on an incomplete finite domain constraint solver. We conclude with a prototype implementation of the method and some aspects about our future work. 1 Introduction In realworld applications, constraints represent conditions
Improved Melanoma Diagnosis Support System Based on Fractal Analysis of Images
"... Abstract Computational intelligence is finding more and more applications in computer aided diagnostics, helping doctors to give the right decicisions. In dermatology it is extremely difficult to perform automatic diagnostic differentiation of malignant melanoma basing only on dermatoscopic images. ..."

Next we present a practial approach of using fractal methods in skin lesion analysis. At the end results and comparison of skin lesions analasis are given.
CEC2013 Congress on Evolutionary Computation, IEEE Parallelization Strategies for Evolutionary Algorithms for MINLP
"... Abstract — Two different parallelization strategies for evolutionary algorithms for mixed integer nonlinear programming (MINLP) are discussed and numerically compared in this contribution. The first strategy is to parallelize some internal parts of the evolutionary algorithm. The second strategy i ..."

that the first parallelization strategy represented by arGA is inferior to the serial version of MIDACO, even though if massive parallelization via GPGPU is used. In contrast to this, theoretical and practial tests demonstrate that the parallelization strategy of MIDACO is promising for cputime expensive MINLP
Size of OBDD representation of 2level redundancies functions
, 2000
"... We consider an explicit boolean function depending on n = (i + 1) j variables encoding 2level cascade redundancies in critical systems. We establish lower and upper bounds on the size of its OBDD representation. The exact lower bound of this function is comprised between e min( i 2 ; j 2 ) ..."
