1. 1. !secure(system) <=?=> !safe(system) : On Security and Safety of Industrial Software Systems

   Författare :Marcus Lindner; Per Lindgren; Valeriy Vyatkin; Knut Åkesson; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; embedded systems; hard real-time; concurrency; model of computation; safety-critical; safety; security; industrial automation; RTFM; real-time for the masses; Embedded Systems; Inbyggda system;

   Sammanfattning : The focus of our research work is on readily accessible, embedded, real-time development with concurrency support. To this end, we develop the Real-Time For the Masses (RTFM) programming framework with a model of computation based on tasks and resources and that stipulates a timing semantics. LÄS MER

3. 2. Towards a Safe System Approach to Prevent Health Loss among Motorcyclists

   Författare :Matteo Rizzi; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stability; ABS; Safe System; Motorcycle; Powered Two Wheelers; Antilock Brakes;

   Sammanfattning : Health loss among motorcyclists is a global road safety problem for which innovative countermeasures are needed. While the traditional motorcycle safety approach has focused on protective gear and rider education, the Safe System approach adopted in Sweden and other countries implies that the road, the vehicle and the road user, in conjunction with a safe speed limit, should interact to create a safe road transport system.

4. 3. A Computational Framework for Control of Machining System Capability : From Formulation to Implementation

   Författare :Andreas Archenti; Cornel Mihai Nicolescu; Mamoru Mitsuishi; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machining system; Stability; Statistical Dynamics; Elastic Linked System ELS ; Operational Dynamic Parameters ODP ; Loaded Double Ball Bar LDBB ; Virtual Machining System Engine VMSE ; Contactless Excitation and Response System CERS .; SRA - Production; SRA - Produktion;

   Sammanfattning : Comprehensive knowledge and information about the static and dynamic behaviour of machine tools, cutting processes and their interaction is essential for machining system design, simulation, control and robust operation in safe conditions. The very complex system of a machine tool, fixture and cutting tools during the machining of a part is almost impossible to model analytically with sufficient accuracy. 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. Probabilistic System Effects in Timber Structures

   Författare :Martin Hansson; Avdelningen för Konstruktionsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggnadsteknik; Building construction; Anläggningsteknik; Construction technology; first order reliability method; Monte Carlo simulation; system effect; sheathed parallel member system; structural timber; roof truss;

   Sammanfattning : The main purpose of the performed research presented in this thesis is to increase the understanding of the effect of variability of strength properties on the reliability of timber structural systems. Compared to other structural materials such as steel and concrete, structural timber has a considerably higher variability of strength both within and between members. LÄS MER
