For efficient firing in sloping grate bark furnaces, it is important to control the ash line position on the grate. The ash line is the border between burning fuel and fuel which is burned out (ash). Here, the problem of detecting the ash line with an image processing system is treated. The presentation of trend curves to the operator is of special interest. The process is slow and trend curves pr
Although Procellariiform nestlings develop independent endothermic thermoregulation at an early age, they may not be able to meet the high energetic costs of maintaining a constant high body temperature during prolonged periods of fasting or cold exposure. The ability to reduce body temperature and enter torpor could therefore represent an important survival strategy in the Procellariiformes. It i
There are many reasons why heat transfer and heat exchangers play a key role in the development of sustainable energy systems as well as in the reduction of emissions and pollutants. In general, all attempts to achieve processes and thermodynamic cycles with high efficiency, low emissions, low costs include heat transfer and heat exchangers to a large extent. It is known that sustainable energy de
Innovation och utveckling är viktigt för en dynamisk samhällsutveckling. Immaterialrättslig ensamrätt gör att individer och företag vågar satsa på nya idéer och under hela 1900-talet har skyddet successivt förstärkts. Lagstiftningsarbete pågår i det enskilda landet, på EG-nivå, men också internationellt. Det finns dock anledning att fråga sig om utvecklingen ibland drivs så hårt att andra väsentli
Focusing on the concept of competence, the paper proposes that the concept itself is engendered, i.e., it is a concept that is defined in male terms. As such it functions to define women as a group as lacking or devoid of the traits, characteristics and/or behaviors that are necessary for being "seen" and being perceived of as competent in educational settings and on the labour market. The paper i
The paper will give a brief overview of developments and strategies in the private education sector in the People's Republic of China. The focus of the presentation will be on the question of how globally migrating ideas about marketization and privatization of education are reflected, negotiated, and (partly) transformed in the Chinese context. It will be demonstrated that ideas and practices of
