Abstract: As consequence of global warming extreme weather events might become more frequent and severe across the globe. The evaluation of the impact of climate change on extremes is then a crucial issue for the resilience of infrastructures and buildings and is a key challenge for adaptation planning. In order to assess changes in extreme maximum a nd minimum air temperatures, Regional Climate Models outputs and observed data series have been analyzed and a new technique for the assessment of climate model uncertainty has been developed. Considering different radiation scenarios , s ome results are pre sented for the Italian Mediterranean region proving the ability of the method to define factors of change for climate extremes as well as to assess their evolution in time , allowing at the same time to estimate the uncertainty range of the model . Extending the analysis to different climate models it will be possible to take into account in climate change impact study also model uncertainty in

Abstract: The multi-wire sawing of silicon using a steel wire coated with diamond grits (diamond wire) is an important process in the semiconductor and photovoltaic industry. The cut is performed in the industry by pushing a silicon ingot against a diamond wire web that moves in a pilgrim-mode (forwards and backwards). As the cut direction and cutting speed of the wire change multiple times during the operation, it is very difficult to perform a proper investigation of the cutting process. In order to study the multi-wire sawing of monocrystalline silicon (mono-Si), a new experimental setup has been proposed. Based on literature research and industry know-how, the main features necessary for the proposed wafering test rig have been defined as follows: i) use of a short wire looped segment; ii) cut with controllable constant wire speed and iii) permit to track specific diamond grains after each cut for wear analysis. In order to fulfill these prerequisites, the first step is to butt-weld diamond
