  2. 11. Experimental Observations and Theoretical Modeling of Lightning Interaction with Tall Objects

    Author : Helin Zhou; Rajeev Thottappillil; Gerhard Diendorfer; Daohong Wang; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tall objects; Upward lightning initiation; Charge density distribution; Upward positive lightning; Upward bipolar lightning;

    Abstract : This thesis investigates various discharge processes associated with upward lightning initiated from tall objects, both experimentally and theoretically, trying to bridge the knowledge-gap in understanding the mechanisms of the phenomena.Upward lightning initiation has attracted a great deal of interest during recent years due to the proliferation of tall communication towers and wind turbines.

  5. 13. An Observer-Based Technique with Trace Links for Requirements Validation in Embedded Real-Time Systems

    Author : Jiale Zhou; Kristina Lundqvist; Kristian Sandahl; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer Science; datavetenskap;

    Abstract : With the growing complexity of embedded real-time systems, requirements validation becomes an ever-more critical activity for developing such systems. Studies have revealed that most of the anomalies, discovered in the development of complex systems, belong to requirement and specification phases. READ MORE

  6. 14. An Ontological Approach to Safety Analysis of Safety-Critical Systems

    Author : Jiale Zhou; Kristina Lundqvist; Ibrahim Habli; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hazard analysis; ontologies; safety-critical systems; safety requirements elicitation; Computer Science; datavetenskap;

    Abstract : Safety-critical systems (SCSs) have become an intrinsic part of human dailylife in multiple domains, such as automotive, avionics, and rail industries. Such systems are not only required to implement the functionality they should provide, but also have to satisfy a set of safety requirements in order to ensure the mitigation of hazardous consequences.

  7. 15. Genes and proteins controlled by cGMP-PKG during retinal degeneration

    Author : Jiaming Zhou; Lund Oftalmologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; retinal degeneration; cell death; cGMP-PKG; organotypic explant culture; RNA sequencing; mass spectrometry;

    Abstract : prevalence was reported as 1:3000-4000 worldwide, making it the main reason for blindness in the working population in industrial countries. The mutations of over 70 genes have been related to this genetic disorder, and there is generally no effective treatment, except for gene therapy for the RPE65 mutations. READ MORE
