Autonomous vehicles learn to find the best path

Kristoffer Bergman, doctoral student in Automatic Control, describes in his licentiate thesis methods to enable autonomous vehicles find the fastest or most energy-efficient path from starting point to a destination, even if obstacles are in the way.

Flying vehicles find their own path

Flying vehicles, manned and unmanned, are today equipped with large numbers of sensors. The vehicles are still controlled manually, but WASP doctoral student Per Boström-Rost shows in his licentiate thesis how the control can be made more autonomous.

Andreas Nobel celebrates eco-friendly wood

Nothing beats wood for the manufacture of furniture, says Andreas Nobel, newly inaugurated professor of furniture design at Malmstens Linköping University.

LiU’s Tetralith ranks 74th in TOP500 list

Two supercomputers in Sweden are among the world’s most powerful supercomputers. The 2019 TOP500 list is dominated by the United States and China, but Sweden also appears, with Tetralith at National Supercomputer Centre, NSC, and Beskow at KTH.

Self-injuring young girls overestimate negative feedback in social media simulation

Adolescent girls who self-injure feel that they receive more negative feedback than they actually receive, and are more sensitive to thumbs down responses, compared to other girls. These are the findings presented by Irene Perini, researcher at CSAN.

The interlayers help perovskite crystallisation for light-emitting diodes

Scientists at LiU working with colleagues from China have shown how to achieve efficient perovskite light-emitting diodes (LEDs). In an article in Nature Communications, they provide guidelines on fabricating high-quality perovskite light emitters.

Pain signalling in humans more rapid than previously known

Pain signals can travel as fast as touch signals, according to a new study. The discovery of a rapid pain-signalling system challenges our current understanding of pain.

Biogas can increase the capacity of pulp and paper mills

The wastewater streams from kraft mills have been considered to be too difficult to digest for biogas production, despite containing large quantities of organic substances. Eva-Maria Ekstrand reveals a solution in her doctoral thesis.

Unclear regulations lead to misleading reports

The accounting standard IAS 10 is ambiguous, and may lead to the annual reports of companies giving a misleading picture. The standard should be thoroughly revised. Jan Kellgren, professor at LiU, makes these points in a newly published article.

Biogas production can be more efficient, with the right choice of organic material

Luka Šafarič doctoral thesis shows that the organic material that is fed into the reactor affects the thickness of the sludge, and ultimately, the reactor’s efficiency.

Multiresistant bacteria spread widely in Vietnamese hospitals

Around half of patients admitted to hospital in Vietnam are carriers of multiresistant intestinal bacteria. The longer the patients are in hospital, the greater is the risk that they have been infected by these bacteria.

Big city growth escalates the urban-rural divide

Microdata from Swedish population registers provide new insights into cities' economic growth paths. The data reveal a surge in regional inequality, with more and more resources flowing to cities atop the urban hierarchy.

Mistra to continue funding research into circular economy transition

The Swedish Foundation for Strategic Environmental Research has granted SEK 47 million for four years to Mistra REES. The aim of the programme is to facilitate the transition by Swedish manufacturing industry to a circular economy.

Artificial muscles powered by glucose

Artificial muscles made from polymers can now be powered by energy from glucose and oxygen, just like biological muscles. This advance may be a step on the way to future autonomous microrobots powered by biomolecules in their surroundings.

Helping elderly hear better

Hearing researchers at Linköping University are addressing the hearing problems of the elderly. The aim is to improve the quality of life of the millions of elderly who suffer from hearing loss.

LiU doctoral student to meet Nobel laureates

Tim Cornelissen, IFM, is one of the young researchers invited to this year’s Lindau Nobel Laureate Meeting in Germany. 580 undergraduates, doctoral students, and postdocs will have the opportunity to meet and discuss science with Nobel laureates.

Sustainable food production and the art of expanding the ecosystem

Global food needs are increasing. In the short term, agriculture requires better conditions. In the long term, we must transform how business is done for a sustainable society – with green services, according to LiU researchers in business marketing.

He prevents the spread of infection

An outbreak of an infectious animal disease can have disastrous consequences for the complete social economy of a country. LiU researcher Tom Lindström has the task of improving preparedness for such an outbreak in the US.

New ways to stop tuberculosis

Maria Lerm, newly installed professor at Linköping University, wants to find out whether it is possible to strengthen the body’s own protection against tuberculosis. Tuberculosis is the deadliest bacterial disease in the world.

Food production with greater sustainability – how?

The food we eat has a profound effect on the world. Researchers at LiU have examined possible measures to increase sustainability in Swedish food production.

Dogs mirror owner’s stress

The levels of stress in dogs and their owners follow each other, according to a new study. The scientists believe that dogs mirror their owner’s stress level, rather than vice versa.
