OBJECTIVES Underweight, overweight, and obese women aged 18-34 years were compared with normal weight women of the corresponding age according to socioeconomic, psychosocial, health behaviour, self reported global and psychological health, and locus of control characteristics. METHODS The 2000 public health survey in Scania is a cross-sectional study. A(More)
OBJECTIVE To investigate the association between psychosocial work conditions and unemployment, and low leisure-time physical activity. DESIGN/SETTING/PARTICIPANTS/MEASUREMENTS The 2000 public health survey in Scania is a cross-sectional postal questionnaire study with a 59% participation rate. A total of 5,180 persons aged 18-64 years who belonged to the(More)
This longitudinal study investigates the impact of social participation, trust and the combinations of social participation and trust on the incidence of first time acute myocardial infarction (AMI) in the population of Scania, southern Sweden. It is based on the cross-sectional 2000 public-health survey in Scania with a 59% participation rate and 13,604(More)
OBJECTIVES To investigate gender differences in daily smoking prevalence in different age groups in southern Sweden. METHODS The 2004 public-health survey in Skane is a cross-sectional study. A total of 27,757 persons aged 18-80 years answered a postal questionnaire, which represents 59% of the random sample. A logistic regression model was used to(More)
AIMS To investigate the association between socioeconomic status, unemployment and self-rated psychological health, taking economic stress and horizontal trust into account. DESIGN/SETTING/PARTICIPANTS/MEASUREMENTS The 2008 public health survey in Skåne is a cross-sectional postal questionnaire study with a 55% participation rate. A random sample was(More)
State-of-the-art texture descriptors typically operate on grey scale images while ignoring color information. A common way to obtain a joint color-texture representation is to combine the two visual cues at the pixel level. However, such an approach provides sub-optimal results for texture categorisation task. In this paper we investigate how to optimally(More)
A significantly increased water regime can lead to inundation of rivers, creeks and surrounding floodplains- and thus impact on the temporal dynamics of both the extant vegetation and the dormant, but viable soil-seed bank of riparian corridors. The study documented changes in the soil seed-bank along riparian corridors before and after a major flood event(More)
In this paper, we consider a system of cognitive radios that collaborate with each other with the aim of detecting the random waveforms being emitted from licensed users. We study the problem of fusing the statistics from collaborating sensors, assuming that they send their statistics to a base station, where the final decision is made. The main(More)
On the basis of the use of the generalized likelihood ratio test (GLRT) and model order selection techniques, an improved event detector is proposed herein by incorporating the spatial correlation existing in measurements coming from neighboring wireless sensors. Such a spatial dependence is proposed to be extracted through the use of the so-called(More)
In collaborative spectrum sensing, spatial correlation in the measurements obtained by sensors can be exploited by adopting Generalized Likelihood Ratio Test (GLRT). In this process the GLRT provides a test statistics that is normally based on the sample covariance matrix of the received signal samples. Unfortunately, problems arise when the dimensions of(More)
