The parameters of PMSM with inter-turn fault are identified using a time-stepping finite element method (FEM). Analytical expressions (AE) uses the estimated parameters for fault analysis similar to FEM analysis. The fault waveforms, terminal voltages, obtained from the AE models are used for inter turn fault (ITF) detection, using Stator Flux Linkage DC offset (SFDO). A comparison is made between
The effect of airborne particulate matter on human health is today of considerable research interest. Essential parameters include elemental composition sampling with low pressure cascade impactors and analysis by particle induced x-ray emission spectroscopy (PIXE). It is shown that the aerosol generated by arc welding operations is several orders of magnitude denser than aerosols in ambient air.
Det är statens suveräna rätt att reglera utlänningars närvaro inom dess territorium. Denna rätt är däremot inte utan begränsningar. Artikel 1 i protokoll nr. 7 till Europeiska konventionen om skydd för de mänskliga rättigheterna säkerställer rättssäkerhetsgarantier i samband med utvisningen av utlänningar. Dessa rättssäkerhetsgarantier måste tillgodoses vid utvisningsförfarandet i de medlemsstaterIt is the sovereign prerogative of the state to regulate the presence of aliens within its territory. This right, however, is not without limits. Article 1 of Protocol No. 7 to the European Convention on Human Rights ensures procedural safeguards relating to the expulsion of aliens. These safeguards must be considered in expulsion proceedings by those Member States having ratified the protocol.
The amount of carbon uptake by vegetation is an important component to understand the functioning of ecosystem processes and their response/feedback to climate. Recently, a new diagnostic model called the Southampton Carbon Flux (SCARF) Model driven by remote sensing data was developed to predict terrestrial gross primary productivity (GPP) and successfully applied in temperate regions. The model
Dissolved organic carbon (DOC) loading is rarely estimated in tropical watersheds. This study quantifies DOC loading in the Rukarara River Watershed (RRW), a Rwandan tropical forest and agricultural watershed, and evaluates its relationship with hydrological factors, land use and land cover (LULC), and topography to better understand the impact of stream DOC export on watershed carbon budgets. The
This work deals with the problem of direction of arrival estimation of interferometric synthetic aperture radar (InSAR) signals in presence of layover. The focus here is on realistic acquisition systems with a low number of phase centres and nonuniform array geometry. An interpolated array approach is proposed, in order to apply spectral estimation techniques designed for uniform linear arrays. In
A new generalized bimodal traffic stream model deriving theoretically (i.e., via some underlying model of driver behavior) from (local) equilibrium solutions of a kinetic equation of vehicular traffic is presented and shown to have the correct flow behavior at jam density. This bimodal traffic stream model depends not only on parameters such as the desired speed w, the headway σ(0) at jam density
This paper presents a study with the intent to examine the opportunities provided by creating and using simulation models of software development processes. A model of one software development project was created through means of system dynamics, with data collected from documents, interviews and observations. The model was simulated in a commercial simulation tool. The simulation runs indicate th
Our existing urban environment has a significant potential to increase the use of renewable energy, mainly by using solar irradiation for heat and electricity. Quantification of the solar potential by means of a solar map is the first step in the acceleration process for using more solar energy in our urban environments. A solar map is a GIS system providing the annual solar irradiation on buildin
Computer-based design analysis is nowadays of utmost importance for most engineering design projects. However, this brings some challenges, among them that of the collaboration between engineering designers and design analysts. Since they work with, and are responsible for, different areas, they do not necessarily have full insight into each other’s way of working. The issue of integration between
It is well documented that human modification of the hydrological cycle has profoundly affected the flow of liquid water across the Earth's land surface. Alteration of water vapor flows through land-use changes has received comparatively less attention, despite compelling evidence that such alteration can influence the functioning of the Earth System. We show that deforestation is as large a drivi
Children can and should be encouraged to take an active part in their own care. With the introduction of online health care centers, where the main interaction is provided through digital consultations, the process for including the child must be revised. In addition to the medical and legal challenges, the digital interface needs to be designed so that the parent is encouraged to involve the chil
The dedicated production of biomass crops and the collection of residues in agriculture and forestry can lead to undesirable negative impacts and it is crucial that practices are found that ensure that these impacts are avoided or mitigated as far as possible. This chapter concerns the use of biomass for energy and the connection between increased bioenergy use and land use change (LUC). Land use
This chapter presents an assessment of green house performance (GHG) performance of current and prospective Swedish ethanol production and outlines a strategy for improving the GHG performance on an expanding ethanol market. Calculations are presented that consider process integration and establishment of biocombines producing multiple products, the use of a broader resource base including lignoce
Five students of a rescue training school cycled at 50 W for 20 minutes at 20 °C before walking up to 30 minutes in a climatic chamber at 55 °C and 30 % relative humidity. Four different types of clothing ensembles were used differing in terms of thickness and thermal insulation value were tested on separate days. All subjects completed 28-30 minutes in light clothing, but quitted after 20-27 minu
In the paper, we consider the problem of routing and bandwidth allocation in networks that support elastic traffic. We assume that the bandwidth demand between each source-destination (S-D) pair is specified in terms of a minimum and maximum value, and a set of flows between each S-D pair is allowed to realize these demands. (We say that a set of flows realizes the demand associated with an S-D pa
Two different approaches for developing virtual environments (VE) for brain injury rehabilitation are described and discussed. The two VEs are built with the VR software World Up in the form of virtual vending and automatic service machines. The result from the first approach is a virtual cash dispenser that has been tested on five patients with brain injury. Improving the VE according to the test
Approaches to determining the factuality of diagnoses and findings in clinical text tend to rely on dictionaries of marker words for uncertainty and negation. Here, a method for semi-automatically expanding a dictionary of marker words using distributional semantics is presented and evaluated. It is shown that ranking candidates for inclusion according to their proximity to cluster centroids of se
Poor acoustic conditions in learning spaces have a detrimental effect on the speaker's health and constitute a risk factor for voice disorders. Previous research indicates that an acoustic refurbishment of the learning space has the potential to increase well-being and decrease voice-related health problems among teachers, but the research is scarce. In this study, we aim to investigate how differ
