    ABSTRACT: The problem of order-preserving matching has gained attention lately. The text and the pattern consist of numbers. The task is to find all the substrings in the text which have the same length and relative order as the pattern. The problem has applications in analysis of time series. We present a new sublinear solution based on filtration. Any algorithm for exact string matching can be used as a filtering method. If the filtration algorithm is sublinear, the total method is sublinear on average. We show by practical experiments that the new solution is more efficient than earlier algorithms.

    ABSTRACT: Over the past few years, shared spaces for students, entrepreneurs and faculty have become popular on university campuses. This study aims at increasing understanding on how a new co-working space is developed on campus, and what the different stakeholders’ roles are in the development process. The single case study is a recently emerged ‘learning, networking, and innovation platform’ for energy, named the Energy Garage. The Energy Garage is available to all university students, faculty, and businesses with an interest in energy related topics. Using archived material and interviews with key stakeholders, the study analyses the development path of the Energy Garage, placing special focus on the role of students during the different phases. The study finds that, while the initiative for Energy Garage came from faculty, students have successfully been given a major role in the planning and operational management of the space. The findings provide an insight into other similar initiatives, which continue to gain popularity on university campuses.

    ABSTRACT: The effect of hydrogen charging on twinning stress and surface microstructure was investigated in 10M Ni-Mn-Ga ferromagnetic shape memory alloy. During hydrogen charging on the bulk sample, cross-like pits formed which gradually evolve into diamond shaped cracks on the surface. The cell boundaries are well visible and there is about 20μm wide area next to the cell boundary is less cracked. The evolution of the microstructure before and after hydrogen charging is also studied by transmission electron microscope (TEM). There is no visible change in the average twinning stress during hydrogen charging even if the surface is dramatically covered with pits and micro cracks.
