Escape planning in realistic fire scenarios with Ant Colony Optimisation
2014
Published version of an article from the journal:Applied Intelligence Also available on Springerlink: http://dx.doi.org/10.1007/s10489-014-0538-9 An emergency requiring evacuation is a chaotic event, filled with uncertainties both for the people affected and rescuers. The evacuees are often left to themselves for navigation to the escape area. The chaotic situation increases when predefined escape routes are blocked by a hazard, and there is a need to re-think which escape route is safest. This paper addresses automatically finding the safest escape routes in emergency situations in large buildings or ships with imperfect knowledge of the hazards. The proposed solution, based on Ant Colony …
Climate Change and Childhood Respiratory Health: A Call to Action for Paediatricians
2020
Climate change (CC) is one of the main contributors to health emergencies worldwide. CC appears to be closely interrelated with air pollution, as some pollutants like carbon dioxide (CO2), nitrogen oxides (NOx) and black carbon are naturally occurring greenhouse gases. Air pollution may enhance the allergenicity of some plants and, also, has an adverse effect on respiratory health. Children are a uniquely vulnerable group that suffers disproportionately from CC burden. The increasing global warming related to CC has a big impact on plants’ lifecycles, with earlier and longer pollen seasons, as well as higher pollen production, putting children affected by asthma and allergic rhinitis at ris…
A Comparison of Multi-objective Algorithms for the Automatic Design Space Exploration of a Superscalar System
2013
In today’s computer architectures the design spaces are huge, thus making it very difficult to find optimal configurations. One way to cope with this problem is to use Automatic Design Space Exploration (ADSE) techniques. We developed the Framework for Automatic Design Space Exploration (FADSE) which is focused on microarchitectural optimizations. This framework includes several state-of-the art heuristic algorithms.
Planck-scale effects on WIMP dark matter
2014
There exists a widely known conjecture that gravitational effects violate global symmetries. We study the effect of global-symmetry violating higher-dimension operators induced by Planck-scale physics on the properties of WIMP dark matter. Using an effective description, we show that the lifetime of the WIMP dark matter candidate can satisfy cosmological bounds under reasonable assumptions regarding the strength of the dimension-five operators. On the other hand, the indirect WIMP dark matter detection signal is significantly enhanced due to new decay channels.
Limits on the parameters of the equation of state for interacting dark energy
2010
Under the assumption that cold dark matter and dark energy interact with each other through a small coupling term, $Q$, we constrain the parameter space of the equation of state $w$ of those dark energy fields whose variation of the field since last scattering do not exceed Planck's mass. We use three parameterizations of $w$ and two different expressions for $Q$. Our work extends previous ones.
Green Chemistry in Higher Education: State of the Art, Challenges, and Future Trends
2018
Nowadays, there is increasing interest in global sustainability, and thus, university students would like to know how human actions affect the health status of our planet. This is mainly due to their basic knowledge of problems such as global warming and greenhouse gases. Students would like to gain knowledge on how to safeguard the earth for future generations. This must involve changes in education programs at interested institutions and universities. To ensure that future generations of chemists are equipped with proper knowledge, significant efforts are needed. Thus, this article aims to present the history of green chemistry, its milestones, and ideas on how to teach this subject. A di…
The Warm Water in my Heart - The Meanings of Love among the Finnish Country Population in the Second Half of the 17th Century
2011
This article examines the meanings and contents given to the emotion called love in early modern Finnish culture. The study takes as its starting point three distinct love affairs found in the district court records. These cases violated the boundaries between the estates, for the women were of noble birth and the men came from peasant backgrounds. Historical love is here approached using the theories of Catherine A. Lutz, Carol & Peter Stearns and Barbara Rosenwein. Following these scholars, love is seen as a cultural and social phenomenon, bound up with the culture and mentalities of the era. In early modern times marriage was the basis of society and promoted by both the state and the ch…
Extremely rapid acclimation of Escherichia coli to high temperature over a few generations of a fed-batch culture during slow warming
2014
This study aimed to demonstrate that adequate slow heating rate allows two strains of Escherichia coli rapid acclimation to higher temperature than upper growth and survival limits known to be strain-dependent. A laboratory (K12-TG1) and an environmental (DPD3084) strain of E. coli were subjected to rapid (few seconds) or slow warming (1 degrees C 12 h(-1)) in order to (re) evaluate upper survival and growth limits. The slow warming was applied from the ancestral temperature 37 degrees C to total cell death 46-54 degrees C: about 30 generations were propagated. Upper survival and growth limits for rapid warming (46 degrees C) were lower than for slow warming (46-54 degrees C). The thermal l…
Long-term changes of precipitation in Latvia
2010
This study investigated long-term variability and trends in Latvia's annual, seasonal, monthly and daily precipitation using data from 10 meteorological stations for the period 1925–2006 and from station Riga University for the period 1850–2006. The obtained results indicate that during the 20th century a significant increase in precipitation has occurred in the cold season while the warm period showed a decreasing tendency. The annual precipitation totals showed a slight decrease, at half of the studied stations, due to opposite tendencies in cold season and warm season. The long-term trend in the annual precipitation in Riga (from 1850) was positive with large interannual and interdecadal…
