1. 1. A Step Towards the Design of Collaborative Autonomous Machines : A Study on Construction and Mining Equipment

   Författare :Martin Frank; Tobias Larsson; Christian Johansson Askling; Åsa Ericson; Blekinge Tekniska Högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Fully autonomous construction and mining machines are not science fiction anymore. For special applications, these types of machinery are well known for several years. The construction and mining industries are ripe for innovative product and service offers, including automated and fully autonomous machines at a larger scale. LÄS MER

3. 2. Chinese women and consumer culture : discourses on beauty and identity in advertising and women's magazines 1985-1995

   Författare :Perry Johansson; Frank Dikötter; Stockholms universitet; []
   Nyckelord :HUMANITIES and RELIGION; HUMANIORA och RELIGIONSVETENSKAP; sinologi; Sinology;

   Sammanfattning : Chinese women and consumer culture are studied through semiotics and discourse analysis of advertisements and beauty editorials from women's magazines. The trajectory of Chinese consumption and advertising development during the last two decades is outlined and the changing notions of female beauty after Mao is examined, describing the resurfacing gender differences and the renewed importance of body and gender, together with the commodification of women and female beauty.

4. 3. Predator effects on behaviour and life-history of prey

   Författare :Tomas Brodin; Frank Johansson; Bradley Anholt; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; activity; behaviour; behavioural syndromes; damselfly; development; growth; life-history; predator-prey interaction; predation risk; thinning; Freshwater ecology; Limnisk ekologi;

   Sammanfattning : In this thesis I investigate predator-induced effects on behavioural and life-history characteristics of prey. At any moment a given predator is capable of attacking a small number of prey. LÄS MER

5. 4. Safe Autonomy under Uncertainty: Computation, Control, and Application

   Författare :Yulong Gao; Karl H. Johansson; Lihua Xie; ‪Frank Allgöwer; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Safe autonomy; shared autonomy; probabilistic controlled invariant set; invariant cover; linear temporal logic; temporal logic tree; safe teleoperation; automated car overtaking; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Safety is a primary requirement for many autonomous systems, such as automated vehicles and mobile robots. An open problem is how to assure safety, in the sense of avoiding unsafe subsets of the state space, for uncertain systems under complex tasks. LÄS MER

7. 5. Sub-lethal Effects of Anthropogenic Contaminants on Aquatic Invertebrates

   Författare :Warren Kunce; Frank Johansson; Jan Örberg; Sarah Josefsson; Jes Rasmussen; Uppsala universitet; []
   Nyckelord :ecotoxicology; sub-lethal; behavior; biomarkers; thermal tolerance; pesticides; pyrethroids; neonicotinoids; pharmaceuticals; antihistamines; microplastics; mixtures; freshwater; invertebrates; chironomids; damselflies; snails; Biology with specialization in Animal Conservation; Biologi med inriktning mot zoologisk bevarandebiologi;

   Sammanfattning : Anthropogenic contaminants are considered to play a substantial role in the decline of freshwater invertebrate diversity. Sub-lethal effects of many of these contaminants on behaviour and life-history traits of aquatic invertebrates may contribute to their decline. LÄS MER
