For example, a heat source is required when experimenting on Heat Transfer and an electric source for basic DC/AC study, Ohm's Laws e.t.c. Many laboratories use batteries for all those experiments, with well-known effects of their consumption to the environment, This study is based on the idea of discovering a way to produce the electricity that is required for all these experiments with the use of Renewable Energy Sources. We herein present one of the devices of that prototype Laboratory.

Although MBL-effects upon student learning and conceptual development in undergraduate course of physics are un-doubtful, there are certain constraints in Hellenic schools, that eliminate those advantages. Our study aims to propose an innovative and utilitarian approach for the Hellenic Physics' Lab curriculum that will provide pupils with hands-on inquiring activities with the use of Video-Based Labs (VBLs).

The design bases on a parallel memory organization minimizing the resources required to support integer and sub-pixel modes of search, while it sustains the required throughput of pixels to the SAD calculator. A speculative execution technique improves the number of cycles required by the search process. The architecture is programmable including an instruction set for actions common to all the block-matching techniques, while circuits introduced at compile time accommodate individual actions of the most demanding algorithms such as MVFAST and PMVFAST. A FPGA implementation validates HDTV video performance.
