  1. 1. A Transformation of Controlled Natural Language Behavioural Requirements into Modal Sequence Diagram Simulation Models for Requirement Conflict Detection

    University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

    Author : Alexander Styre; [2017-06-21]
    Keywords : model-driven engineering MDE ; requirements engineering RE ; model-driven requirements engineering MDRE ; ScenarioTools; scenario markup language SML ; scenario description language SDL ; modal sequence diagram MSD ; message sequence chart MSC ; live sequence chart LSC ; controlled natural language CNL ; deterministic transformation;

    Abstract : PURPOSE: Specifying requirements in a semi-formal notation, such as a controlled natural language(CNL), allows reduction of ambiguity and underspecification in requirement specifications, as the notationuses well defined semantics and enforces consistency and conformance to syntactical rules. Contradictingrequirements can be problematic to detect in practice depending on the size and complexity of therequirement specification. READ MORE

  2. 2. Robust Design and Analysis of Automotive Collision Avoidance

    University essay from Göteborgs universitet/Institutionen för matematiska vetenskaper

    Author : Anders Sjöberg; [2017-02-10]
    Keywords : Simulation-based optimization; response surface methodology; radial basis functions; multi-objective optimization; Pareto optimal solutions; trigger edge; tunable parameters; false intervention; robustness; positive and negative performance scenarios.;

    Abstract : Automotive collision avoidance systems help the driver to avoid or mitigate a collision. The main objective of this project is to find a methodology to improve the performance of Volvo's automotive collision avoidance system by optimizing its configurable parameters. READ MORE

  3. 3. A new approach to simulating the draping of prepreg composites manufactured by hand layup

    University essay from KTH/Lättkonstruktioner

    Author : Vincent Maymard; [2017]
    Keywords : ;

    Abstract : Kinematic drape simulations, of applying woven reinforcements to complex geometries, have to date largely focused on characterising the ply shape and the deformations from fitting it to the surface of a mould; amongst other manufacturing management outputs. This is increasingly unsatisfactory: it does not allow for any prediction into the effect of geometry and changes on the layup; does not realistically simulate the draping process as achieved by operators; instruct on the process of how to manipulate a ply to achieve the deformations required, or; enable the information gathered to be exploited in simple useful formats.

  4. 4. Application and Control of Robotic Manipulator through PLC

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Andreas Fredmer; [2017]
    Keywords : Robotics; Automation; PLC;

    Abstract : This thesis analyses the background of the kinematics and control of an articulated robotic arm in order to control it’s motor controllers with a custom controller using PLC programming. The goal was to create a MATLAB simulation of a manipulator and then establish a working configuration. READ MORE

  5. 5. The thermal comfort of the cockpit: A pilot's experience

    University essay from KTH/Optimeringslära och systemteori

    Author : Emma Johansson; [2017]
    Keywords : ;

    Abstract : Saab takes great measures to ensure that the cockpit is a great working environment for the pilot. This paper aims to expand the knowledge of thermal comfort by assembling Saab’s atmosphere-, cabin and pilot-models. In order to ensure the viability of the assembled model, a qualitative study was performed with test pilots. READ MORE
