Consider the quadratic family Ta(x) = ax(1-x) for x ∈ [0, 1] and mixing Collet-Eckmann (CE) parameters a ∈ (2, 4). For bounded φ, set φ˜a := φ-∫ φ dμa, with μa the unique acim of Ta, and put (σa(φ))2 := ∫ φ˜2a dμa + 2Σ i>0 ∫ phi;˜a(φ˜a o T1a) dμa. For any mixing Misiurewicz parameter a∗, we find a positive measure set Ω∗ of mixing CE parameters, containing a∗ as a Lebesgue density point, such that

Dominance by cyanobacteria hampers human use of lakes and reservoirs worldwide. Previous studies indicate that excessive nutrient loading and warmer conditions promote dominance by cyanobacteria, but evidence from global scale field data has so far been scarce. Our analysis, based on a study of 143 lakes along a latitudinal transect ranging from subarctic Europe to southern South America, shows th

The Urban Systems and Dynamics group, led by Prof. Nik, advances the boundaries of Building Physics to explore the complex interactions between buildings, urban systems, and climate. Our research focuses on designing and optimizing strategies for buildings and urban systems (with a big focus on energy systems) that drive the sustainable urban transition and enhance the built environment's resilienThe Urban Systems and Dynamics group, led by Prof. Nik, advances the boundaries of Building Physics to explore the complex interactions between buildings, urban systems, and climate.

Datorspel är idag en mångmiljardbransch och den fortsätter att växa, men tyvärr har den grafiska utvecklingen i stor utsträckning lämnat synskadade utanför. Känselgränssnitt erbjuder en fascinerande form av interaktion med virtuella världar. Framförallt gör dessa gränssnitt det lättare för synskadade att tillgodogöra sig virtuella miljöer. I takt med att nya, mer avancerade gränssnitt når konsumen

The principle of force feedback is to design a sensor as a feedback system where the action of the measured variable is compensated by a force generated by feedback. Force feedback has contributed significantly to improve the quality of sensors. A characteristic feature of MEMS devices is that they are subject to random disturbances, such as Brownian motion, Johnson-Nyquist noise, and tunneling no

Feedback controllers are typically applied to computing systems by acting on some quantities ("tunable parameters" in the computer science lexicon, think e.g. of a packet drop rate) in order to attain some goal (e.g., a required bandwidth allocation). In other words, control loops are closed around the computing system, that exposes tunable parameters as control actuators, and allows to measure so

Sown flower strips are increasingly implemented within agri-environment schemes (AES) to increase functional biodiversity and ecosystem services such as pollination or natural pest control, but their effectiveness in achieving these goals remains poorly studied. We tested the performance of experimentally sown annual flower strips specifically designed to promote natural enemies of aphids a

Air emissions are becoming a larger problem in today’s society and therefore the limits are getting stricter. This means that chemical-producing industries which create multiple byproducts, acting like air pollutants, requires to improve their emission limiting systems. Johnson Matthey Formox AB is a company who sells licenses and catalysts for formaldehyde production by the FORMOXTM process. Prod

Pollinators provide valuable ecosystem services to agricultural landscapes; however, they are threatened by several factors of decline. Particularly for wild pollinator species, the effects of stressors neither individually nor in interaction with each other are well understood. Pesticide use is known to impart various lethal and sublethal effects on pollinator populations, and this use is likely

Diesel engines are by far the most common means of propulsion aboard ships. It is estimated that around half of their fuel energy consumption is dissipated as low-grade heat. The organic Rankine cycle technology is a well-established solution for the energy conversion of thermal power from biomass combustion, geothermal reservoirs, and waste heat from industrial processes. However, its economic fe
