  • Kalman filter for adaptive learning of two-dimensional look-up tables applied to OCV-curves for aged battery cells
  • 2019
  • Ingår i: Control Engineering Practice. - 0967-0661. ; 84, s. 230-237
  • Tidskriftsartikel (refereegranskat)abstract
    • In online automotive applications it is common to use look-up tables, or maps, to describe nonlinearities in component models that are to be valid over large operating ranges. If the component characteristics change with aging or wear, these look-up tables must be updated online. For 2-D look-up tables, the existing methods in the literature only adapt the observable parameters in the look-up table, which means that parameters in operation points that have not been visited for a long time may be far from their true values. In this work, correlations between different operating points are used to also update non-observable parameters of the look-up table. The method is applied to Open Circuit Voltage (OCV) curves for aged battery cells. From laboratory experimental data it is demonstrated that the proposed method can significantly reduce the average deviation from an aged OCV-curve compared to keeping the OCV-curve from the beginning of the cell's life, both for observable and non-observable parameters.

  • Spatio-temporal aspects of the interplay of cancer and the immune system
  • 2019
  • Ingår i: Journal of Biological Physics. - 0092-0606 .- 1573-0689. ; 45:4, s. 395-400

    • The conventional mean-field kinetic models describing the interplay of cancer and the immune system are temporal and predict exponential growth or elimination of the population of tumour cells provided their number is small and their effect on the immune system is negligible. More complex kinetics are associated with non-linear features of the response of the immune system. The generic model presented in this communication takes into account that the rates of the birth and death of tumour cells inside a tumour spheroid can significantly depend on the radial coordinate due to diffusion limitations in the supply of nutrients and/or transport of the species (cells and proteins) belonging to the immune system. In this case, non-trivial kinetic regimes are shown to be possible even without appreciable perturbation of the immune system.

  • Prenatal essential fatty acid deficiency in mice results in long-term gender-specific effects on body weight and glucose metabolism
  • 2011
  • Ingår i: Molecular Medicine Reports. - 1791-2997. ; 4:4, s. 731-737
  • Tidskriftsartikel (refereegranskat)abstract
    • Essential fatty acids are important for normal growth and development in early life. However, the long-term effects of prenatal essential fatty acid deficiency (EFAD) on the adult metabolism remain to be determined. The aim of this study was to investigate the effects of an EFAD diet given to mice during late gestation on body weight and body composition, and metabolism in the adult offspring. Pregnant dams were given an EFAD or a control diet during the last 10 days of gestation. After delivery, all mice were fed normal chow and the body weight of the offspring was measured weekly. Furthermore, food intake, energy expenditure and intraperitoneal glucose tolera-nce were analysed in the adult offspring in addition to body composition (analysed by dual-energy X-ray absorptiometry), plasma levels of leptin, triglycerides and cholesterol. The body weight was lower in the EFAD offspring as compared to the controls during the first 4 weeks of age, and remained lower in the females throughout the study. Lean body mass and plasma leptin levels were also lower in the female EFAD offspring as compared to the controls. Male EFAD offspring were found to have higher fasting glucose and insulin levels as well as higher insulin levels during the glucose tolerance test compared to the controls. However, no differences were found in blood lipids, food intake or energy expenditure between EFAD and control mice of either gender. These results demonstrate that an EFAD diet given during the last 10 days of gestation results in long-term gender-specific effects on body weight and insulin sensitivity in the adult offspring.

  • A pattern recognition framework for detecting dynamic changes on cyclic time series
  • 2015
  • Ingår i: Pattern Recognition. - Elsevier. - 0031-3203 .- 1873-5142. ; 48:3, s. 696-708
  • Tidskriftsartikel (refereegranskat)abstract
    • <p>This paper proposes a framework for binary classification of the time series with cyclic characteristics. The framework presents an iterative algorithm for learning the cyclic characteristics by introducing the discriminative frequency bands (DFBs) using the discriminant analysis along with k-means clustering method. The DFBs are employed by a hybrid model for learning dynamic characteristics of the time series within the cycles, using statistical and structural machine learning techniques. The framework offers a systematic procedure for finding the optimal design parameters associated with the hybrid model. The proposed  model is optimized to detect the changes of the heart sound recordings (HSRs) related to aortic stenosis. Experimental results show that the proposed framework provides efficient tools for classification of the HSRs based on the heart murmurs. It is also evidenced that the hybrid model, proposed by the framework, substantially improves the classification performance when it comes to detection of the heart disease.</p>

  • An Automatic Tool for Pediatric Heart Sounds Segmentation
  • ????
  • Annan publikation (övrigt vetenskapligt)abstract
    • <p>In this <sub>paper,</sub> we present a novel algorithm for pediatric heart sound segmentation, incorporated into a graphical user interface. The algorithm employs both the Electrocardiogram (ECG) and Phonocardiogram (PCG) signals for an efficient segmentation under pathological circumstances.First, the ECG signal is invoked in order to determine the beginning and end points of each cardiac cycle by using wavelet transform technique. Then, first and second heart sounds within the cycles are identified over the PCG signal by paying attention to the spectral properties of the sounds. The algorithm is applied on 120 recordings of normal and pathological children, totally containing 1976 cardiac cycles. The accuracy of the segmentation algorithm is 97% for S1 and 94% for S<sub>2</sub> identification while all the cardiac cycles are correctly determined.</p>
