On the Efficient Frequency Estimation of a Single Tone

The frequency estimation of a single tone corrupted by additive white Gaussian noise has received significant attention over the last decades due to its wide applicability in signal processing. In this paper, we propose a computationally fast and statistically improved hybrid single tone estimator which outperforms other recently proposed approaches, lowering the signal-to-noise ratio at which the

Den (o)hållbara förpackningen

I Den [o] hållbara förpackningen analyseras svenska konsumentförpackningar från 1930-talet fram till idag. Boken består av tre delar där läsaren först får lära känna mjölkförpackningarna, som är livsmedelsbranschens kanske vanligaste men samtidigt mest krävande förpackning. Därefter behandlas läkemedelsförpackningarna, en kategori som alltid har kännetecknats av ett högt säkerhetstänkande. Slutlig

Långvarig smärta

Vård och behandling av personer med långvarig smärta är en utmaning. Vården kan inte bara rikta sig mot smärtan i sig utan måste omfatta hela den komplexitet som uppstår när flera olika faktorer interagerar med såväl smärtan som varandra på olika sätt. Detta kräver god kunskap bland vårdpersonal och då inte bara om hur smärta kan lindras utan även om hur livet förändras vid långvarig smärta. Inne

Conceptual Metaphors of Science : Prolegomena to a Cognitive History of Science

The cognitive abilities explained by cognitive science and cognitive semantics can inform us concerning the use of metaphors in science. The thesis is that abstract ideas rest on experiences of the concrete world. In this paper I will explain the use of conceptual metaphors in science, with examples from the mechanistic worldview of the 17th and 18th century. If we proceed from the way people thin

Radiocesium in the forest and forest industry, Studies on the flow, occurrence and technological enhancement of radionuclides in the forest industry with emphasis on radiocesium.

In the aftermath of the nuclear weapons testing and as compared with agriculture, the forest industry has received relatively little attention in spite of its large-scale use of radiocesium- contaminated wood and water. After the Chernobyl nuclear power plant accident in 1986, numerous studies of the forest environment have been conducted with respect to radionuclide transfer through the forest ec

Molecular regulation of hematopoietic stem cells

Hematopoietic stem cells (HSCs) are ultimately responsible for the all mature blood cell production. They can primarily be found in the bone marrow (BM) at a low frequency (~0.02%). Unlike other blood cells, HSCs have a high degree of self-renewal capacity, the process where upon cell division, at least one daughter cell has the same properties as the stem cell it was generated from. In addition,
