Predicting stiffness and strength of birch pulp:Polylactic acid composites

2016

This paper studies failure of birch pulp–polylactic acid composites. Stiffness and strength are calculated using the theory of short fibre composites and the results are compared to experimental data. The results differed from the experimental values by 0–6%. With less aligned fibres the short fibre theory is not feasible. The performance of the 40 wt% birch pulp – polylactic acid composite is predicted with X-ray microtomography based finite element modelling, and the results are compared with experiments. Stiffness results differed from experiments by 1–17% . By adding into the models a third material phase representing the interface between the fibres and the matrix, the stress–strain c…

Images of Japan and the Japanese : the representations of the Japanese culture in the popular literature targeted at the Western World in the 1980s-1…

2002

This study draws together a number of popular issues: images, intercultural communication and Japan. In particular, Japan has been a popular topic for at least the last three decades. The Japanese Economical Miracle awoke a real boom in the Western literature at the end of 1970s, and in the 1980s the Miracle became a fashionable topic in the Western world. Because of this a great amount of studies, books and articles is available for those who want to learn about this nation. The aim of this study is to examine “images of Japan and the Japanese in the Western world” on the basis of the literature targeted at Western audiences during the big boom.

Effects of pyrolysis temperature on the hydrologically relevant porosity of willow biochar

2018

Biochar pore space consists of porosity of multiple length scales. In direct water holding applications like water storage for plant water uptake, the main interest is in micrometre-range porosity since these pores are able to store water that is easily available for plants. Gas adsorption measurements which are commonly used to characterize the physical pore structure of biochars are not able to quantify this pore-size range. While pyrogenetic porosity (i.e. pores formed during pyrolysis process) tends to increase with elevated process temperature, it is uncertain whether this change affects the pore space capable to store plant available water. In this study, we characterized biochar poro…

Interpretation of journalistic photographs as an instrument of visual literacy education

2016

Images are produced, used and distributed on an enormous scale. However, the skills of understanding, interpreting and using images as well as thinking and learning in terms of images are taken for granted, and thus, they are not sufficiently taught and developed, especially in higher education. The need for introducing visual literacy into the curriculum was identified in late 1960s, but no concrete guidelines have followed. This study proposes to apply interpretation of journalistic photographs as an instrument of visual literacy education. The main focus is on the image interpretation process and the kinds of meanings viewers apply to a photograph in the interpretation process. In each o…

Analyysi Helsingin Sanomien romanikerjäläiskuvista

2012

Romanikerjäläiset muodostavat sekä Suomessa että muualla Euroopassa syvälle ja laajalle ulottuvan yhteiskunnallisen kysymyksen, jonka monimutkaisuus juontuu osaltaan romanikansan raskaasta historiasta. Tässä tutkimuksessa lähestyn romanikerjäläisiä koskevaa keskustelua tulkitsemalla visuaalista aineistoa. Selvitän ensinnäkin sitä, miten romanikerjäläisiä esitetään sanomalehtikuvissa. Toiseksi tarkastelen, millaista todellisuutta tätä kautta tuotetaan. Näkökulmani kumpuaa siitä lähtökohdasta, että kuvilla on huomionarvoista vaikutusta uutisoinnin kokonaisuudessa. Tutkimusaineisto muodostuu Helsingin Sanomista vuonna 2010 kerätyistä köyhyyteen ja kärsimykseen liittyvistä kuvista, joista tutki…

Tuulivoimaloiden hyväksyttävyys maisemaelementtinä

2011

Maisema koostuu luonnonympäristöstä ja rakennetusta ympäristöstä ja se muuttuu koko ajan luonnollisista ja ihmisten aiheuttamista syistä johtuen. Maisema rakentuu erilaisista objektiivisista elementeistä, mutta maisemakokemus on jokaisen katsojan henkilökohtai-nen näkemys. Tuulivoimala on nykyaikainen energiantuotantolaitos. Uusiutuvan energian tuotantoa pyri-tään Suomessa lisäämään reilusti lähivuosina. Tuulivoimalat tuottavat päästötöntä energi-aa, joten myös ilmastonmuutoksen hillitsemiseksi tuulivoimatuotannon lisääminen on tar-peellista. Suomessa on tuulivoimatuotannolle sopivia alueita runsaasti. Tuulipuistojen ra-kentaminen vaatii kuitenkin ympäristövaikutusten tarkastelua. Tuulivoim…

SLMotion - An extensible sign language oriented video analysis tool

2014

We present a software toolkit called SLMotion which provides a framework for automatic and semiautomatic analysis, feature extraction and annotation of individual sign language videos, and which can easily be adapted to batch processing of entire sign language corpora. The program follows a modular design, and exposes a Numpy-compatible Python application programming interface that makes it easy and convenient to extend its functionality through scripting. The program includes support for exporting the annotations in ELAN format. The program is released as free software, and is available for GNU/Linux and MacOS platforms. peerReviewed
