The Unbalanced Linguistic Aggregation Operator in Group Decision Making
2012
Published version of an article in the journal: Mathematical problems in engineering. Also available from Hindawi: http://dx.doi.org/10.1155/2012/619162 Many linguistic aggregation methods have been proposed and applied in the linguistic decision- making problems. In practice, experts need to assess a number of values in a side of reference domain higher than in the other one; that is, experts use unbalanced linguistic values to express their evaluation for problems. In this paper, we propose a new linguistic aggregation operator to deal with unbalanced linguistic values in group decision making, we adopt 2-tuple representation model of linguistic values and linguistic hierarchies to expres…
Approximate analytic and numerical solutions to Lane-Emden equation via fuzzy modeling method
2012
Published version in the journal: Mathematical Problems in Engineering. Also available from the publisher: http://dx.doi.org/10.1155/2012/259494 A novel algorithm, called variable weight fuzzy marginal linearization VWFML method, is proposed. Thismethod can supply approximate analytic and numerical solutions to Lane-Emden equations. And it is easy to be implemented and extended for solving other nonlinear differential equations. Numerical examples are included to demonstrate the validity and applicability of the developed technique.
D-Optimal Design for Parameter Estimation in Discrete-Time Nonlinear Dynamic Systems
2012
Published version of an article from the journal: Mathematical Problems in Engineering. Also available from the publisher:http://dx.doi.org/10.1155/2012/296701 An optimal input design method for parameter estimation in a discrete-time nonlinear system is presented in the paper to improve the observability and identification precision of model parameters. Determinant of the information matrix is used as the criterion function which is generally a nonconvex function about the input signals to be designed. To avoid the locally optimizing problem, a randomized designmethod is proposed bywhich a globally optimizing test plan other than input signals may be obtained. Then the randomized design ca…
Landing gear suspension control through adaptive backstepping techniques with H∞ performance
2011
Author's version of a chapter published in the book: Proceedings of the 18th IFAC World Congress 2011. Also available from the publisher at: http://dx.doi.org/10.3182/20110828-6-IT-1002.00589 Landing gear suspension systems fulfill the tasks of absorbing the vertical energy of the touch-down as well as providing passenger and crew comfort with a smooth ground ride before take-off and after landing. They are also designed to have optimal performance in the case of a hard landing. In general, the tasks of aircraft landing gears are complex and sometimes lead to a number of contradictory requirements. Although there are existing modifications of aircraft shock absorbers to reduce the problem, …
Balansen mellom kontekstuelle krav og pasientenes behov : ergoterapeuters erfaringer knyttet til eldre pasienters overgangsfase fra sykehus til eget …
2014
Background and aim: Coping in daily activities when discharged from hospital to own home can be challenging for older people. Internationally, there is a number of studies on this topic, but similar studies in Norway and Nordic countries seem to be scarce. The aim of this study was to illuminate occupational therapists’ experiences of how to promote coping of daily activities in older patients who are discharged from hospital to home. Methods: A qualitative design with individual interviews was used. A purposive sample of eight occupational therapists were included, four worked in hospitals and four in community health services, respectively. Initially the interviews had an open form, but a…
Is It Possible to Predict an Athlete’s Behavior? The Use of Polar Coordinates to Identify Key Patterns in Taekwondo
2019
Elite sport psychologists help athletes develop planned competition strategies from a technical-tactical perspective, through the observation and analysis of previous performances. The aim of this study was to analyze the behavioral patterns used to score points in the 2012 London Olympic Games, by using a mixed observational methodology through a polar coordinate analysis. This analysis is a representation made into four quadrants of the relationships found between focal behavior [i.e., giving score points, (SC)] and conditioned behaviors considered as key factors in taekwondo, occurring before and after the focal behavior (i.e., retrospective/prospective behavior as indicated for each qua…
Valuing American Options with Implementation
2017
Master's thesis Business Administration BE501 - University of Agder 2017 This master thesis aims to value American put options by using di erent numerical methods. Three valuation methods for valuing an American put option will be pre- sented and analyzed; the binomial method, the implicit nite di erence method and the least squares Monte Carlo approach (LSM). Due to the opportunity of early exercise of American option contracts, our goal is to nd the optimal exercise strategy which maximizes the payo by using numerical methods. We provide examples of how to implement each algorithm in di erent types of software. A comparison of the methods are given at the end.
