  2. 1. Track circuits’ robustness : Modeling, measurement and simulation

    Author : Emilio Rodriguez; Ajit Kumar Verma; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Track circuit; Relay; False positive signals; Signalling in railway; Modelling; Simulation; Testing; Robustness; Interoperability; Reliability; Railway Infrastructure; Drift och underhållsteknik; Operation and Maintenance Engineering;

    Abstract : In countries with rough weather conditions, frequent delays cause railway companies to waste time and money. Many of these delays are related to the train detection systems, as the old DC track circuits are still used in some countries, including Sweden, our case study. READ MORE

  4. 2. Software Robustness: From Requirements to Verification

    Author : Ali Shahrokni; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; robustness; quality requirements; requirements patterns; robustness testing; requirements specification; non-functional requirements; requirements refinement;

    Abstract : The importance of software quality increases as software products become more intertwined with our everyday lives. A critical software quality attribute is robustness, i.e. that the software shows stable behavior in stressful conditions and when receiving faulty inputs. READ MORE

  5. 3. Maximum a posteriori deconvulution of ultrasonic data with applications in nondestructive testing : Multiple transducer and robustness is

    Author : Tomas Olofsson; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Ultrasonic pulse-echo testing; nondestructive testing; maximum a posteriori estimation; linear minimum mean squared error estimation; robust filtering; multivariable filtering; sparse deconvolution; Materialvetenskap; Materials science; Teknisk materialvetenskap; Signal Processing; signalbehandling;

    Abstract : In the thesis, various aspects of deconvolution of ultrasonic pulse-echo signals in nondestructive testing are treated. The deconvolution problem is formulated as estimation of a reflection sequence which is the impulse characteristic of the inspected object and the estimation is performed using either maximum a posteriori (MAP) or linear minimum mean square error (MMSE) estimators.

  6. 4. Model-Implemented Fault Injection for Robustness Assessment

    Author : Rickard Svenningsson; Martin Törngren; Sasikumar Punnekkat; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fault Injection; Model-Implemented Fault Injection; Robustness; Assessment; ISO 26262; ISO 61508; Software;

    Abstract : The complexity of safety-related embedded computer systems is steadilyincreasing. Besides verifying that such systems implement the correct functionality, it is essential to verify that they also present an acceptable level of robustness. READ MORE

  7. 5. Tooth Interior Fatigue Fracture&Robustness of Gears

    Author : Magnus MackAldener; KTH; []
    Keywords : Gear; TIFF; FEM; Taguchi Method; Robustness; Interior Crack; Idler;

    Abstract : The demands the automotive gear designer has to considerduring the gear design process have changed. To design a gearthat will not fail is still a challenging task, but now lownoise is also a main objective. Both customers and legalregulations demand noise reduction of gears. Moreover, thequality of the product is more in focus than ever before. READ MORE
