Completely randomized RRT-connect: A case study on 3D rigid body motion planning

2015

Nowadays sampling-based motion planners use the power of randomization to compute multidimensional motions at high performance. Nevertheless the performance is based on problem-dependent parameters like the weighting of translation versus rotation and the planning range of the algorithm. Former work uses constant user-adjusted values for these parameters which are defined a priori. Our new approach extends the power of randomization by varying the parameters randomly during runtime. This avoids a preprocessing step to adjust parameters and moreover improves the performance in comparison to existing methods in the majority of the benchmarks. Our method is simple to understand and implement. …

A Priori Methods

1998

In the case of a priori methods, the decision maker must specify her or his preferences, hopes and opinions before the solution process. The difficulty is that the decision maker does not necessarily know beforehand what it is possible to attain in the problem and how realistic her or his expectations are. The working order in these methods is: 1) decision maker, 2) analyst.

Approximate solution of the Fokker-Planck-Kolmogorov equation

2002

The aim of this paper is to present a thorough investigation of approximate techniques for estimating the stationary and non-stationary probability density function (PDF) of the response of nonlinear systems subjected to (additive and/or multiplicative) Gaussian white noise excitations. Attention is focused on the general scheme of weighted residuals for the approximate solution of the Fokker-Planck-Kolmogorov (FPK) equation. It is shown that the main drawbacks of closure schemes, such as negative values of the PDF in some regions, may be overcome by rewriting the FPK equation in terms of log-probability density function (log-PDF). The criteria for selecting the set of weighting functions i…

Häälehtien nais- ja mieskuva

2011

Pro gradu -tutkielma käsittelee häälehtien nais- ja mieskuvaa. Tarkastelun kohteena on kaksi suomalaista häälehteä, Häät ja Mennään naimisiin, joiden sana-aineiston perusteella kartoitetaan sitä, miten naisista ja miehistä lehdissä puhutaan. Ensisijaisen mielenkiinnon kohteena ovat naisiin ja miehiin viittaavat nimitykset sekä heitä kuvailevat adjektiivit ja partisiipit. Tutkimusta taustoittavat erilaiset kriittisen tekstintutkimuksen teoriat, jotka toisaalta ohjaavat kiinnittämään huomiota tekstin sananvalintoihin, toisaalta käsittelemään sanoja osana niiden laajempia käyttöyhteyksiä, konteksteja. Odotuksenmukaisesti häälehdistä piirtyy kuva varsin morsiankeskeisenä mediana. Tähän vaikutta…

Multi-model ensemble simulations of olive pollen distribution in Europe in 2014

2017

Abstract. A 6-models strong European ensemble of Copernicus Atmospheric Monitoring Service (CAMS) was run through the season of 2014 computing the olive pollen dispersion in Europe. The simulations have been compared with observations in 6 countries, members of the European Aeroallergen Network. Analysis was performed for individual models, the ensemble mean and median, and for a dynamically optimized combination of the ensemble members obtained via fusion of the model predictions with observations. The models, generally reproducing the olive season of 2014, showed noticeable deviations from both observations and each other. In particular, the season start was reported too early, by 8 days …

Pathways of Innovation: The I-District Effect Revisited

2018

The I-district effect establishes the existence of dynamic efficiency in Marshallian industrial districts in the form of a positive innovative differential comparing to the average of the economy. The hypothesis has been empirically validated for the case of technological innovation using patent indicators. Empirical research has assumed that all types of patentable figures (utility models, national patents, EPO, WIPO) have the same weight regardless of its actual or expected market value, which may be questionable given the differences in coverage, protection and cost of each figure. In this article, we question the existence of the I-district effect when each patent is weighted by its exp…

Single-shot, dual-mode, water-immersion microscopy platform for biological applications

2018

A single-shot water-immersion digital holographic microscope combined with broadband (white light) illumination mode is presented. This double imaging platform allows conventional incoherent visualization with phase holographic imaging of inspected samples. The holographic architecture is implemented at the image space (that is, after passing the microscope lens), thus reducing the sensitivity of the system to vibrations and/or thermal changes in comparison to regular interferometers. Because of the off-axis holographic recording principle, quantitative phase images of live biosamples can be recorded in a single camera snapshot at full-field geometry without any moving parts. And, the use o…

Assessment of environmental impacts with life cycle methods in nanotechnology industry

2013

This thesis inspected how nanotechnology companies in Finland have been assessing the environmental impacts of their products and processes. The research focused on using life cycle based methods that take into account the environmental impacts during the whole lifetime of a product. The subject was studied mainly through three qualitative case studies. Millidyne Oy, Vaisala Oyj and UPM-Kymmene Oyj were interviewed. Also quantitative research was used to some extend in the form of a company questionnaire. This research showed that only 13 % of nanotechnology companies in Finland have done environmental assessments with life cycle methods, and that even this figure is likely to be biased and…
