    Abstract : Popular Abstract in Swedish Hos järnvägsfordon ger den låga friktionen mellan hjul och räls upphov till långa bromssträckor, i allmänhet längre än lokförarens siktsträcka. Om föraren påbörjar en inbromsning först när han ser ett hinder på spåret kan det vara för sent. READ MORE

  3. 3. Deterministic Silicon Pillar Assemblies and their Photonic Applications

    Abstract : Popular Abstract in English What is a photographic camera flash good for? The easy answer is “to illuminate”. There is more to it though: the duration of a camera flash is usually much shorter than the shutter speed of the camera. This allows us to take sharp pictures of fast objects with an inexpensive camera. READ MORE
