Environmental regulations are continuously pushing lower emissions with an impact on the combustion process in gas turbines (GTs). As a consequence, GT combustors operate in very lean regimes (i. e., at relatively low temperature) to reduce NOx formation. Unfortunately, stabilization becomes a challenge for these lean premixed flames. The extremely unsteady dynamics of swirl stabilized flames pres

Denna antologi innehåller ett slumpmässigt urval av helt vanliga kinesers opublicerade livsberättelser, författade mellan 1950 och 1981. Originalberättelserna har snappats upp på loppmarknader i Beijing, Shanghai och Nanjing och har här översatts till svenska av studenter vid Språk- och litteraturcentrum vid Lunds universitet. De skildrar inte bara nio liv som kontrarevolutionär, arkivarie, teknik

This chapter proposes a novel offline text dependent writer verification method based on Gray Level Co-occurrence Matrix (GLCM). The method is used to combine the result of Dual Tree Complex Wavelet Transforms (DT-CWT) and GLCM features to enhance the GLCM feature performance. The texture is a very important characteristic, which is used to verify the known writer from unknown writers. We have use

Review of a book on pietism in Sweden in the 1720s.

Large eddy simulations (LES) are performed for single and multiphase jets in crossflow (JICF). The multiphase JICF are compared to the single-phase case for the same momentum and mass flow ratios but with droplets of different sizes. Multiphase JICF have stronger counterrotating vortex pairs (CVPs) than a corresponding single-phase JICF. Moreover, their trajectories are higher and their induced wa

Pixel classification of watershed satellite image is a challenging task in remote sensing. Uses of Particle Swarm Optimisation and Cellular Automata are significant methods in watershed image segmentation. This paper proposes a method of pixel classification using a new hybrid Particle Swarm Optimization-Cellular Automata approach. The proposed unsupervised method identifies clusters using 2-Dimen

Skogar täcker ca 31% av jordens landyta och lagrar stora mängder kol i biomassa och i marken. I klimatavtalet från Paris 2015 lyfts skogars roll som sänkor och reservoarer av kol fram och undertecknande länder uppmanas att implementera strategier för hållbart skogsbruk som ytterligare förstärker skogars roll som sänkor av växthusgaser. Ett aktivt skogsbruk påverkar klimat och miljö på många olika Forest ecosystems cover 31% of the terrestrial land area and store large amounts of carbon in biomass and in soils. The 2015 Paris Agreement recognizes the importance of sinks and reservoirs of greenhouse gases (GHGs) in forests and the importance of enhancing them through sustainable forest management policies. Managing forests for climate mitigation purposes is, however, complex since management
