Multi-Pitch Estimation and Tracking Using Bayesian Inference in Block Sparsity

n this paper, we consider the problem of multi-pitch estimation and tracking of an unknown number of harmonic audio sources. The regularized least-squares is a solution for simultaneous sparse source selection and parameter estimation. Exploiting block sparsity, the method allows for reliable tracking of the found sources, without posing detailed a priori assumptions of the number of harmonics for

The precondition of success in Iran’s water resources management: easy access to hydro-climatic data

Abstract in Uncoded languagesEasy access to hydro-climatic data is a necessary precondition for the progress and success of any water resources research project. Without (easy) access to these data, realistic and reliable assessment of a catchment under study is impossible. The aim of this note is not to discuss the importance of the collection of hydro-climatic data but to emphasise the worthines

Högsta förvaltningsdomstolen och principföljsam prjeudikatbildning i skattemål

I artikeln analyseras Högsta förvaltningsdomstolens roll och ansvar att bevilja prövningstillstånd och bilda prejudikat. Betydelsen av god prejudikatbildning lyfts fram och ett urval av avgöranden illustrerar hur domstolen kan skapa prejudikat för konkreta rättsfrågor, men också av mer generell art. Det finns ett antal exempel på hur domstolen har tagit tillfället i akt att göra detta, men författ

Action spectroscopy in biology

Action spectroscopy is a method for identifying the light-absorbing chromophore in a photobiological or biochemical process by comparing the efficiency of radiation of different wavelengths in driving the process. This chapter explains the principle and gives several ex-amples from the history of biology of what has been achieved using this technique.

Logistics Management in Practice - towards theories of complex logistics

Purpose – The purpose of this paper is to present findings concerning what logistics managers perceive as being difficult and challenging, and what implications this may have for further advances in the logistics discipline. Design/methodology/approach – The point of departure for this study was to reflect on perceived problems, uncertainties, trends, and solutions in logistics, and how they are h
