In this work, we present a method for estimating the parameters detailing an unknown number of linear chirp signals, using an iterative sparse reconstruction framework. The proposed method is initiated by a re-weighted Lasso approach, and then use an iterative relaxation-based refining step to allow for high resolution estimates. The resulting estimates are found to be statistically efficient, ach

Accidents and injuries caused by electricity are work environment risks for electricians. About a 100 cases are reported annually to the Swedish Work Environment Authority. The safety culture at the electricians’ workplaces can affect the successfulness of safety management and the prevention of injuries. This paper presents preliminary questionnaire and interview findings on the perceived workpla

The organisational network of global environmental governance (GEG) mirrors the complexity of the planet's manifold and overlapping ecosystems. Bursting onto the international stage in the 1970s, environmental issues began to be addressed by a series of new international organisations, most of them affiliated with the United Nations. Some of them, such as the United Nations Environment Programme (

This paper discusses the problem of tolerance management in the construction industry. Despite industrialized building having increased the demand for higher precision, the problem of tolerance management still occurs. Selecting appropriate tolerances is an optimization problem, where the cost of accuracy and the costs due to lack of tolerance need to be balanced. Problems of tolerance management,

Research in service management and marketing has in the past decade highlighted the concept of value creation. In service organizations value creation is described as a process in which the customer uses a company's value proposition in a meaningful way. However, research has tended to ignore the contextual meaning, and few empirical studies have shown how context is relevant. Therefore, the aim o

The purpose of this paper is to provide an ex-post evaluation of the effectiveness of the South Korean Green New Deal (GND) as an instrument to deliver both an economic recovery and improved environmental performance. We use the energy sector as the main scope for our analysis when measured against climate-related indicators (e.g. CO2 emissions, energy intensity, share of renewable energy in suppl

The subject of this thesis is the clinical use of the oesophageal electrode in electrocardiology. The three areas covered are oesophageal electro- cardiography, the biophysics of transoesophageal atrial stimulation (TAS) and the clinical utility of TAS. The literature is reviewed with respect to these areas. TAS was performed in 64 patients with documented supraventricular tachycardia (SVT) or a

The aim of the current project (“Swedish Phonetics ’39-‘69”) is to provide an account of the historical, social, discursive, and rhetoric con-ditions that determined the emergence of pho-netic science in Sweden between 1939 and 1969. The inquiry is based on a investigation in four areas: how empirical phonetic data were analysed in the period, how the discipline gained new knowledge about phonetic

I denna bok utforskas den rättsliga hanteringen av duellbrott som ärekränkningar och dueller med dödlig utgång under stormaktsväldets slutskede. Med inspiration från New Cultural History och teorier om manlighet och våld analyseras lagtexter, rättsfall, prästers och rättslärdas skrifter samt anklagade duellanters brev och nådeansökningar. Studien fokuserar på hur den rättsliga diskursen kring duelThis dissertation examines duelling crimes in Sweden during the first half of the 18th century. During this period such crimes could involve verbal insults concerning honour as well as duelling, resulting in death. Inspired by the methods and perspectives of New Cultural History and by theories of masculinity the study argues that masculine violence is a cultural category that is historically deve

An antenna system is disclosed that includes two or more antennas and an impedance matching network. The antennas of the antenna system are closely separated, such as by a distance of no more than a wavelength of received signals divided by two. The impedance matching network is adapted to respond to and counteract performance degradation resulting from cross coupling between the antennas. Related
