1. 1. Återkoppling i interaktion : En studie av klassrumsbaserad bedömning i frisörutbildningen

   Författare :Anna Öhman; Hector Pérez Prieto; Marie Tanner; Christian Lundahl; Karlstads universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Classroom assessment; feedback; vocational education; multimodal interaction; social semiotics; conversation analysis; Pedagogiskt arbete; Educational Work;

   Sammanfattning : The present dissertation concerns social organization of feedback in ongoing hairdressing education. The central aim is to explore feedback between teacher and student in multimodal interaction within classroom assessment, as co-production of action and student’s participation. LÄS MER

3. 2. Cykler och loopar i Salongen : En studie av återkoppling i frisörklassrummet

   Författare :Anna Öhman; Hector Pérez Prieto; Anna Lena Göransson; Marie Karlsson; Anders Jönsson; Karlstads universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Feedback; assessment; classroom; multimodal social semiotics; communication; vocational education; knowing; Återkoppling; bedömning; yrkesutbildning; multimodal socialsemiotik; kommunikation; kunnande; klassrum; Pedagogiskt arbete; Educational Work;

   Sammanfattning : The interest in this empirical study aims at assessment, more precisely feedback as part of ordinary activities within hairdressing education. The study investigates feedback practices related to assessment of knowing during production, with focus on communication between student and teacher. LÄS MER

4. 3. Relay Feedback and Multivariable Control

   Författare :Karl Henrik Johansson; Institutionen för reglerteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robotics; Automation; Frequency methods; Process control; Sequential control; Automatic tuning; Control education; Laboratory process; Performance limitations; Decentralized control; Multivariable zero; Multivariable systems; Hybrid control; Nonlinear dynamics; Limit cycles; Oscillations; Relay feedback; Sliding modes; control engineering; Automatiska system; robotteknik; reglerteknik;

   Sammanfattning : This doctoral thesis treats three issues in control engineering related to relay feedback and multivariable control systems. Linear systems with relay feedback is the first topic. Such systems are shown to exhibit several interesting behaviors. LÄS MER

5. 4. On Robot Feedback from Range Sensors : Reliable Control by Active Reduction of Uncertainty and Ambiguities

   Författare :Jonas Nygårds; John Hallam; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robot gripping and docking; LQG-feedback; posture estimation; Gaussian sum; optronic sensing; sheet of light range camera; time-of-flight laser; specular reflection s; multiple scattering; range ghosts ; active reduction of ambiguities; reliability; uncertainty; tolerances;

   Sammanfattning : This thesis is on modelling and experimental tests when non contact sensing isused for feedback control in robotics. The motion of the robot is to be controlled relative to objects in the surrounding workspace during operations like gripping/docking, surface following, shape measuring etc. LÄS MER

7. 5. Two strategies for dealing with uncertainty in social-ecological systems

   Författare :Åsa Svenfelt; Göran Finnveden; Karl-Henrik Dreborg; Rebecka Milestad; Philip J. Vergragt; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Futures studies; social-ecological systems; feedback loops; environmental policy; environmental quality objectives; participation; scenarios; Environmental engineering; Miljöteknik;

   Sammanfattning : The scale of environmental problems is increasing. Globalisation and trade haveweakened the links between the ecosystems in which goods are produced and thecommunities in which they are consumed. LÄS MER
