Thermal performance of five bicycle helmets was evaluated with a thermal manikin head with six zones. Evaluation was made with physical and virtual experimental methods. Ambient temperature maintained at 24 °C and surface temperature of the thermal manikin head was set to 34 °C. Experiments were performed for air velocities of 1.6 m/s and 6 m/s. Heat transfer (W) of four thermal zones was recorded
A maximum likelihood methodology for the parameters of models with an intractable likelihood is introduced. We produce a likelihood-free version of the stochastic approximation expectation-maximization (SAEM) algorithm to maximize the likelihood function of model parameters. While SAEM is best suited for models having a tractable "complete likelihood" function, its application to moderately comple
Detta är den sjätte årsrapporten från Svensk Dagfjärilsövervakning, ett nationelltmiljöövervakningsprogram som koordineras av Lunds universitet på uppdrag avNaturvårdsverket sedan 2010. Svensk Dagfjärilsövervakning är ett samarbete mellan Sveriges Entomologiska Förening, Naturvårdsverket, Lunds universitet, Sveriges lantbruksuniversitet och Länsstyrelserna. Verksamheten möjliggörs av frivilliga laThis is the sixth annual report of the Swedish Butterfly Monitoring Scheme, a national monitoring programme coordinated by Lund University for the Swedish Environmental Protection Agency since 2010. The programme is a partnership between the Entomological Society of Sweden, the Swedish Environmental Protection Agency, Lund University, the Swedish University of Agricultural Sciences and the Swedish
Objectives: In this substudy of the DETO2X-AMI (An Efficacy and Outcome Study of Supplemental Oxygen Treatment in Patients With Suspected Myocardial Infarction) trial, the authors aimed to assess the analgesic effect of moderate-flow oxygen supplementation in patients with suspected acute myocardial infarction (AMI) treated with percutaneous coronary intervention (PCI) and to study the effect of o
Structural interactions between the endoplasmic reticular (ER) and mitochondrial membranes, in domains known as mitochondria-associated membranes (MAM), are crucial hubs for cellular signaling and cell fate. Particularly, these inter-organelle contact sites allow the transfer of calcium from the ER to mitochondria through the voltage-dependent anion channel (VDAC)/glucose-regulated protein 75 (GRP
Event detection is a challenging stage in eye movement data analysis. A major drawback of current event detection methods is that parameters have to be adjusted based on eye movement data quality. Here we show that a fully automated classification of raw gaze samples as belonging to fixations, saccades, or other oculomotor events can be achieved using a machine-learning approach. Any already manua
In iterative receiver structures, soft information becomes available after the decoding stage in the first iteration. This information is used to enhance the quality of the channel estimates for the next iteration. Channel estimation plays a crucial role in multi-user detection because the effective identification sequence for each user strongly depends on the channel characteristics. To combine d
Data from 3 whole body manikins, 2 babies and an adult, were used in the study. All the manikins used the same computer program and similar measuring and control units. No special measurements were made for baby and adult manikin comparison, but available data from earlier measurements was used. The conditions involved air layer insulation measurements (AL), laying on back on an insulating surface
Web sites are exposed to high rates of incoming requests. The servers may become overloaded during temporary traffic peaks when more requests arrive than the server is designed for. An admission control mechanism rejects some requests whenever the arriving traffic is too high and thereby maintains an acceptable load in the system. This paper presents how admission control mechanisms can be designe
Particle-gammagamma and gammagamma-coincidences of the reaction Ni-58(Ar-36, 4 pn)89Mo have been used to gain more information about high spin states in 89Mo and to establish the yrast sequence up to 7.6 MeV excitation energy and probable spin 37/2 h. Spins and parities were assigned on the basis of DCO-ratios measured with the OSIRIS spectrometer and a large volume Ge detector placed at 162-degre
The effect of ultraviolet radiation (UV) (255-325 nm) on stomatal closure was investigated on tef (Eragrostis tef (Zucc) Trotter) in the presence of white light (ca 50 .mu.mol m-2 s-1). The action spectrum showed that UV (ca 2 .mu.mol m-2 s-1, half band width about 10 nm) of 285 nm or shorter wavelengths was very efficient in causing stomatal closure. The effectiveness decreased sharply towards lo
Capsule Nest survival rates could not be explained by distance to habitat edges or other features used by predators. Aims To investigate if predation on Redshank nests was affected by habitat characteristics at a local scale. Methods We examined survival rates of Redshank nests on coastal meadows on the Baltic island of Gotland, Sweden, over two breeding seasons. We analysed nest survival rates
