It has been shown that computational hardness of cognitive tasks affects people’s effort and ability to solve problems reliably. However, prior empirical studies lack generality. They quantify based on particular algorithms or for specific problems. Here, we propose a set measures individual instances task in way is independent any algorithm model can be generalized other Specifically, introduc...

This paper offers a detailed analysis as well tuning and discretization approach of the presented frequency-fixed dual second order generalized integrator based phase-locked loop (FFDSOGI-PLL) for three-phase power systems. The method combines different single- PLL approaches by ensuring high phase- frequency tracking properties. comparison with standard frequency-variable DSOGI-PLL three recen...

This study is concerned with the formulation of three dimensional mapped infinite elements with 1/r and 1/ decay types. These infinite elements are coupled with conventional finite elements and their application to some problems of soil structure interaction are discussed. The effeciency of the coupled finite-infinite elements formulation with respect to computational effort, data preparation a...

A fast and accurate model of the transformer leakage inductance is crucial for optimization-based design galvanically isolated converters. Analytical models are fastly executable, therefore, especially suitable such optimizations. This article compares several analytical per unit length with respect to accuracy computational effort. The considered applicable E-Core U-Core transformers. 2D FEM s...

Medicinal chemistry depends on many other disciplines ranging from organic chemistry andpharmacology to computational chemistry. Typically medicinal chemists use the moststraightforward ways to prepare compounds. The validation of any design project comes from thebiological testing.Studies of the binding site of vinblastine by a single cross—linking experiment identified it asbeing between resi...

This paper attempts to improve the computational efficiency of the well known particle swarm optimization (PSO) algorithm for tackling discrete sizing optimization problems of steel frame structures. It is generally known that, in structural design optimization applications, PSO entails enormously time-consuming structural analyses to locate an optimum solution. Hence, in the present study it i...

A model based structural recognition approach is used for 3D detection and localization of vehicles. It is theoretically founded by syntactic pattern recognition using coordinate grammars and depicted by production nets. The computational effort significantly depends on certain tolerance parameters and the distribution of input data in the attribute domain. A brief theoretical survey of these i...

In this contribution we take a look at the computational effort statistics as described by Koza. We transfer the notion from generational genetic programming to tournament-selection (steady-state) GP and show why, in both cases, the measured value of the effort often differs from its theoretical counterpart. It is discussed how systematic estimation errors are introduced by a low number of expe...
