2. 21. Optimization of Manufacturing Cells Using Discrete Event Models

   Author : Avenir Kobetski; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Flexible Manufacturing; Optimal Scheduling; Supervisory Control Theory; A*; Velocity Balancing; Discrete Events Systems; Mixed Integer Linear Programming; Timed Deterministic Finite Automata; Robot Coordination; Visibility Graphs;

   Abstract : As the name suggests, this thesis is concerned with flexible manufacturing systems (FMS) and their way of living. More specifically, the main objective of this workis to generate working schedules for the moving objects of the manufacturing cells. READ MORE

4. 22. From Words to Voids : Absencing and Haunting in Crimean Semiotic Landscapes

   Author : Natalia Volvach; Christopher Stroud; Caroline Kerfoot; Brigitta Busch; Stockholms universitet; []
   Keywords : HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; semiotic landscapes; linguistic landscapes; multilingualism; bilingualism; indexicality; semiosis; materiality; Linguistic Citizenship; in visibility; erasure; resemiotization; absence; trace; ghost; spectre; haunting; interdiscursivity; Crimea; Ukraine; tvåspråkighet; Bilingualism;

   Abstract : This thesis seeks to contribute to the body of ethnographically-oriented semiotic landscape research by addressing linguistic and non-linguistic signs in the landscapes of contemporary Crimea. It is based on research conducted in the region back in 2017 and 2019 after the Russian annexation but before the full-scale war against Ukraine, which started on 24 February 2022. READ MORE

5. 23. Optimal Coordination of Flexible Manufacturing Systems, with Automatic Generation of Collision- and Dealock-Free Working Schedule

   Author : Avenir Kobetski; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Visibility Graphs; Scheduling; A*; Mixed Integer Linear Programming; Discrete Event Systems; Velocity Balancing.; Robot Coordination; Supervisory Control Theory; Deterministic Finite Automata; Flexible Manufacturing;

   Abstract : The ever more rapidly changing markets pose high demands on the modern industry, often making it necessary to have varied and frequently updated product portfolios. As a consequence, modern industrial systems need to be easily adaptable to different kinds of products, which makes the use of flexible manufacturing systems (FMS) increasingly popular. READ MORE

6. 24. The dis/appearances of violence : When a 'peace-loving' state uses force

   Author : Tua Sandman; Ulrika Mörth; Cecilia Åse; Martin Hall; Stockholms universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Sweden; peace-enforcement; use of force; representation of violence; narrative structuration; identity and foreign policy; de politicisation; dislocation; in visibility; critical war studies; statsvetenskap; Political Science;

   Abstract : The research problem that this dissertation addresses is how and with what implications the use of force in ‘distant’ places is made seen and known at home. As practices change and ‘peacework’ is becoming increasingly violent, the book argues that it is imperative to examine how war ‘comes home’ and to what extent the narratives emerging in public discourse open up for public reflection and (re)consideration.

7. 25. Analysis of Retroreflection and other Properties of Road Signs

   Author : Roxan Saleh; Hasan Fleyeh; Darko Babić; Högskolan Dalarna; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Road traffic signs; retroreflective sheeting material; night-time visibility; supervised machine learning; principal component analysis; prediction; linear regression;

   Abstract : Road traffic signs provide regulatory, warning, guidance, and other important information to road users to prevent hazards and road accidents. Therefore, the traffic signs must be detectable, legible, and visible both in day and nighttime to fulfill their purpose. The nighttime visibility is critical to safe driving on the roads at night.
