Combustion modeling based on a multi-step global reaction mechanism [1] is applied to CFD (Computational Fluid Dynamics) analysis of a scaled swirl-stabilized 4th generation premixed DLE (Dry Low Emission) burner for gas turbines. The flexi-fuel burner consists of a MAIN premixed flame, a premixed PILOT flame and a confined RPL (Rich Pilot Lean) flame. Both steady-state RANS (Reynolds Averaged Nav
In this paper the problem of tracking multiple objects in image sequences is studied. A Hidden Markov Model describing the movements of multiple objects is presented. Previously similar models have been used, but in real time system the standard dynamic programming Viterbi algorithm is typically not used to find the global optimum state sequence, as it requires that all past and future observation
Popular Abstract in Swedish Cytokromer är hem-innehållande proteiner som transporterar elektroner. Hem är den järninnehållande molekyl som binder syre i hemoglobin i de röda blodkropparna i blodet hos t ex människor. Cytokromer har viktiga funktioner i olika typer av organismer: bakterier, växter och djur. Genom att studera vilka gener som behövs för syntesen av cytokromer i bakterien Bacillus subCytochromes are heme-containing proteins that function in electron transfer reactions, e.g. respiration and photosynthesis. There are several different types of cytochromes. C-type cytochromes differ from other types of cytochromes in that the heme group is covalently attached to the polypeptide via thioether bonds to two cysteinyl residues in a consensus motif, Cys-Xaa-Yaa-Cys-His. Cytochrome c o
Popular Abstract in Swedish En betydande del av kemin i naturen och inom industrin äger rum i en omgivning av andra molekyler. Reaktioner, övergångar, interaktioner och andra kemiska processer påverkas nästan alltid utav omgivningen. Dessa modifikationer eller omgivningseffekter beror i grund och botten på växelverkan mellan molekylerna, den så kallade intermolekylära växelverkan. Det speciella faA considerable part of chemistry in nature and industry, takes place in an environment of other molecules. Reactions, transitions, interactions or other chemical processes are almost always modified by the environment. These modifications or environment effects depend ultimately on the interactions between the molecules, the so called intermolecular interactions. The special case of effects induce
During recent years, mobile phone companies have experienced market-related difficulties that result in increasing competition globally. In an attempt to maintain or increase their market share, enterprises reorganize their resources and employ new technologies to sharpen their competitive edges. Moreover, with the globalization, more and more companies become multi-sited. Efficient and timely col
Energy efficiency has gained attention as an important means of ensuring energy supply, fostering countries’ competitiveness and cost-effectively mitigating CO2 emissions. Yet, evaluations of energy efficiency policies are often lacking or insufficient. Moreover, researchers have tended to overlook these types of policies in non-OECD countries, although at this very moment many of these countries
Massive MIMO is considered a key technology for the future wireless communication systems. The promising properties in terms of higher spectral and transmit-energy efficiency are brought by the large number of antennas at the base station (BS). As the number of antennas increases, the aperture of the BS antenna array may become much larger, as compared to today's antenna arrays. In this case, mobi
Introduction For the future conservation, restoration and daily maintenance the need for developing non-destructive and in-situ investigations is vital. At Lund University in Sweden an interdisciplinary research project is being held aiming at, with the help of a mobile system of remote fluorescence lidar, survey and study the facades of historic monuments, and to develop the method and its applic
In this work we compare channel estimation algorithms for use in an iterative CDMA receiver in a block fading environment. The receiver consists of a soft multiuser data estimator, a bank of single user decoders, and a multiuser channel estimator. The multiuser data estimator is implemented as parallel interference canceler with unconditional post-MMSE filtering (PIC-MMSE) and the decoder is a sof
Being able to orient in the vicinity of the home and independently go shopping or visiting a friend can become increasingly difficult when a person suffers from memory decline. The adaption of traditional navigation apps based on satellite positioning could provide an aid, but there are several questions to investigate related to the design and function of such an app. These questions include how
