energy consumption is very high in greenhouses mainly due to off-season production. the main source of its energy supply is fossil fuels. due to the disadvantages of fossil fuels consumption and preventive laws in the incoming years, study on reducing consumption and replacing a part of them with renewable energy is essential. in this research, a solar heating system, equipped with a concentrat...

The world's first Liquefied Hydrogen (LH2) Carrier which will transport LH2 from Australia to Japan has been built. At Japanese port, reducing the tank pressure be required for safe operation. However, reduction cause flashing, leading an excess of venting capacity or liquid leakage. Hence, purpose this research is clarify rate and behavior through experimental numerical approaches respectively...

Packed-bed single-tank thermocline system with reduced cost is an alternative to the conventional two-tank for thermal energy storage. This work systematically explores wall impact on behavior of packed-bed tanks. For this purpose, adapted transient models were developed and fully exploited first time. Two tank configurations investigated compared: a high-temperature pilot-scale steel low-tempe...

The multi-scale modelling of process systems using hierarchical coloured Petri nets for diagnostics is investigated in this report. A case study is used to systematically show the modelling approach using an illustrative example of a tank reactor with cooling jacket. This form of representation shows how CPNs can provide a hierarchically structured framework for advanced fault diagnosis. Resear...

We describe Hidden Semi-Markov Support Vector Machines (SHM SVMs), an extension of HM SVMs to semi-Markov chains. This allows us to predict segmentations of sequences based on segment-based features measuring properties such as the length of the segment. We propose a novel technique to partition the problem into sub-problems. The independently obtained partial solutions can then be recombined i...

Efficient hydrogen storage methods are crucial for the large-scale application of energy. This work studied effects fin structure and injection tube on system performance a tank packed with LaNi5 alloy. An axisymmetric finite element model metal hydride was established. The were added to tank, location efficiency safety during hydriding analyzed. A parametric study wall has been carried out opt...
