The focus of this article is on implementation of real time combustion control by using an FPGA. The feedback used for the controller is the heat release. Due to the desire to avoid using division on the FPGA an alternative way of calculating the polytropic exponent is investigated. When this method is compared against using a constant exponent it shows less fluctuations in regards to cycle to cyc
We here show simulation results that by including a small InAsP heterostructure barrier inside the channel of a InAs nanowire transistor it is possible to increase both the sub threshold slope and on-off ratio with only a modest decrease in the drive current for a fixed gate overdrive. The design is based on the fact that the sharp InAsP heterostructure induces a small barrier in the conduction ba
Popular Abstract in Swedish I många organisationer och företag har vi idag allt äldre medarbetare. Detta kommer troligen att bli ett bekymmer en bit in på 2000-talet, då medarbetare och chefer blir allt äldre eller går i pension. Rekryteringen av nya medarbetare innebär att man får in unga människor, som ofta är mer välutbildade och som har andra värderingar och attityder till arbete och styrning.Research has indicated that there is a growing tendency for young, well-educated people to hold different values toward work and management of work than previous generations. Thus managerial difficulties can arise when these different generations collaborate at work. In order to survive organisations and companies need a managerial leadership that knows how the younger workers view leadership, how
The composition of the labour force is an important economic factor for a country. Often the changes in proportions of different groups are of interest. In this paper we study a monthly compositional time series from the Swedish Labour Force Survey from 1994 to 2005. Three models are studied: the ILR-transformed series, the ILR-transformation of the compositional differenced series of order 1, and
The purpose of the study is to offer an interpretation of surrealism as lived experience or, more exactly, an interpretation of the ways in which the Surrealists themselves respond to and conceive of this experience. Thus, emphasis is put on surrealism as event and process, not as a historically limited phenomenon. The prime source of knowledge about this kind of experience, however, remains Surre

We describe a new method to convert English constituent trees using the Penn Treebank annotation style into dependency trees. The new format was inspired by annotation practices used in other dependency treebanks with the intention to produce a better interface to further semantic processing than existing methods. In particular, we used a richer set of edge labels and introduced links to handle lo
The Nordic Symposium on Building Physics started in Lund in 1987 on an initiative by the Moisture Research Centre in Lund and has been arranged every third year. The venues of the previous symposia were Lund (1987), Trondheim (1990), Copenhagen (1993), Espoo (1996), Gothenburg (1999), Trondheim (2002), Reykjavik (2005), Copenhagen (2008), and Tampere (2011). Now it is organized for the 10th time a
The mechanical stress build up in fibre handling, the dynamical frictional phenomena between fibres and curves surfaces and formation of dust have been studied. Typical are stick slip behaviour and threshold stress levels for formation of dust. The emissions of dust can be limited by electrostatic charging. The measured coefficients of friction of the fibres depend on the mechanical properties, mi
One of the major challenges in analytical chemistry is to find techniques and methods for determinations of low abundance compounds in complex sample matrices. This thesis describes the development of new miniaturised analytical techniques comprising capillary electroseparation combined with mass spectrometric detection. The techniques are rapid, sensitive, efficient, and suitable even for analyte
