In this paper, we elaborate on the issue of analysis-synthesis consistency in sinusoidal coding. Our analysis is based on windowed sinusoids, and uses the same amplitude-complementary window as is used in the overlap-add synthesis. Reconstructions of the neighboring segments are taken into account when forming a particular analysis segment. Sinusoidal estimation is based on a perceptual criterion.
Being able to predict temperature rise inside a machine is as important as predicting its performance and life. Because temperature measurements and computational thermal simulations can be time consuming, thermal paths inside the through-flow universal motor were described by means of simple lumped parameter thermal network. Once the model was built, its unknown convection coefficients were tuned
In Ref. [1], Spencer and Soldatos proposed an enhanced modelling approach for fibre-reinforced composites which accounts for the fibre-bending stiffness in addition to the directional dependency induced by the fibres. Although analytical solutions for simple geometries have been derived over the past years, often subject to specific assumptions such as small deformation kinematics, the application

UNLABELLED: We addressed the questions of how cerebral glucose transport and phosphorylation change under acute hypoglycemia and what the underlying mechanisms of adaptation are.METHODS: Quantitative (18)F-FDG PET combined with the acquisition of real-time arterial input function was performed on mice. Hypoglycemia was induced and maintained by insulin infusion. PET data were analyzed with the 2-t
This paper presents an evaluation of the Swedish pension system, using performance measures that accounts for higher moments of the distribution. The aim of this study is to analyze the relationship between the classical Sharpe ratio and more sophisticated measures, while specifically focusing on the outcome of the default fund in the system. These additional measure consists of the ASSR which acco
Vombsänkan is one of the largest groundwater aquifers in Sweden, it can be divided into a southeastern part with a limestone aquifer and a northwestern part with an aquifer in soil. The limestone aquifer is confined, since it’s overlain by low-permeability soils. All wells for irrigation and municipal purposes are drilled into the limestone rock. The goal is to establish a hydraulic groundwater mo

Efficient use of industrial robots requires a strong interplay between user level commands, the motion control system, and external equipment. It should also be possible for an experienced application engineer to tailor the motion control to a specific application in a convenient way, instead of deficient utilization of the device or tricky user programming which is often the case today. A layered
The hydrologic assessment of a lake water budget can be helpful in achieving proper water management and sustainable water use. A model to analyze a lake water budget was developed and verified for Lake Ikeda, Japan. Lake evaporation was estimated by numerical analyses of lake water temperature and the lake energy budget. Inflow from the lake catchment area and leakage from the lake bottom were es
Compact dual-polarization doppler X-band weather radars (X-WRs) have recently gained attention in Scandinavia for sub-km and minute scale rainfall observations. This study develops a method for merging data from two X-WRs in Dalby and Helsingborg, southern Sweden (operated at five and one elevation angle levels, respectively) to improve the accuracy of rainfall observations. In total, 87 rainfall

Genom Sveriges implementering av EU:s 2014 års upphandlingsdirektiv innehåller svensk rätt sedan år 2017 såväl fakultativa som obligatoriska bestämmelser om ställandet av arbetsrättsliga villkor i offentliga upphandlingar. Denna uppsats identifierar dock flera praktiska svårigheter gällande användandet av dessa bestämmelser på grund av den svenska arbetsmarknadsmodellens särdrag. I brist på en lagThrough Sweden's implementation of EU’s 2014 public procurement directives the Swedish legal system contains since 2017 optional and mandatory statutes regarding specific labour law requirements in public procurement. This thesis however identifies several practical difficulties regarding the use of these statutes because of the characteristics typical for the Swedish labour market model. The

BACKGROUND: The nearly neutral theory of molecular evolution predicts that the efficacy of natural selection increases with the effective population size. This prediction has been verified by independent observations in diverse taxa, which show that life-history traits are strongly correlated with measures of the efficacy of selection, such as the dN/dS ratio. Surprisingly, avian taxa are an excep
Climate change poses one of the most substantial threats to humanity today global greenhouse gas emissions are not reduced drastically in the near future, it can lead to severe consequences worldwide. To address this issue, global and national goals have been developed which aim to foster climate-neutral societies and industries. Since emissions from the construction industry are shown to have a s
The aggregation of the most common natural cyclodextrins (α-, β-, and γ-) in aqueous solutions is addressed by studying the CD-CD interactions using deuterium relaxation rates for deuterium labeled CDs. Relaxation times (T1) and their corresponding relaxation rates (R1 = 1/T1) provide information about the rotational correlation times of CDs and serve as a proxy for solute-solute interactions. Mea
