  text: Application of prognostics and health management (PHM) in the field of Proton
    Exchange Membrane (PEM) fuel cells is emerging as an important tool in increasing
    the reliability and availability of these systems. Though a lot of work is currently
    being conducted to develop PHM systems for fuel cells, various challenges have
    been encountered including the self-healing effect after characterization as well
    as accelerated degradation due to dynamic loading, all which make RUL predictions
    a difficult task. In this study, a prognostic approach based on adaptive particle
    filter algorithm is proposed. The novelty of the proposed method lies in the introduction
    of a self-healing factor after each characterization and the adaption of the degradation
    model parameters to fit to the changing degradation trend. An ensemble of five
    different state models based on weighted mean is then developed. The results show
    that the method is effective in estimating the remaining useful life of PEM fuel
    cells, with majority of the predictions falling within 5\% error. The method was
    employed in the IEEE 2014 PHM Data Challenge and led to our team emerging the
    winner of the RUL category of the challenge.

  text: This paper proposes a quality driven, simulation based approach to functional
    design verification, which applies mainly to IP-level HDL designs with well specified
    test instruction format and is evaluated on a soft microprocessor core MB-LITE
    [5]. The approach utilizes mutation analysis as the quality metric to steer an
    automated simulation data generation process. It leads to a simulation flow with
    two phases towards an enhanced mutation analysis result. First in a random simulation
    phase, an in-loop heuristics is deployed and adjusts dynamically the test probability
    distribution so as to improve the coverage efficiency. Next, for each remaining
    hard-to-kill mutant, a search heuristics on test input space is developed to iteratively
    locate a target test, using a specific objective cost function for the goal of
    killing HDL mutant. The effectiveness of this integrated two-phase simulation
    flow is demonstrated by the results with the MB-LITE microprocessor IP.

  text: HDL-mutation based fault injection and analysis is considered as an important
    coverage metric for measuring the quality of design simulation processes [20,
    3, 1, 2]. In this work, we try to solve the problem of automatic simulation data
    generation targeting HDL mutation faults. We follow a search based approach and
    eliminate the need for symbolic execution and mathematical constraint solving
    from existing work. An objective cost function is defined on the test input space
    and serves the guidance of search for fault-detecting test data. This is done
    by first mapping the simulation traces under a test onto a control and data flow
    graph structure which is extracted from the design. Then the progress of fault
    detection can be measured quantitatively on this graph to be the cost value. By
    minimizing this cost we approach the target test data. The effectiveness of the
    cost function is investigated under an example neighborhood search scheme. Case
    study with a floating point arithmetic IP design has shown that the cost function
    is able to guide effectively the search procedure towards a fault-detecting test.
    The cost calculation time as the search overhead was also observed to be minor
    compared to the actual design simulation time.
