In this study, experimental investigations on a Phase Change Material (PCM) based thermal energy storage system (TES) were carried out. The TES was designed and tested as first step of developing potential product which can be integrated with commercially available ventilation (VEX308) to provide cold intake air for space cooling applications. consisted wedge-shaped flow regions before after an...

This work presents the solutions adopted for the design and the implementation of an autonomous wheeled robot developed for the exploration and mapping of air ventilation ducts. The hardware is based on commercial off-the-shelf devices, including sensors, motors, processing devices and interfaces. The mechanical chassis was designed from scratch to meet a trade-off between small size and availa...

ventilation tube (vt) insertion is the most common otologic operations performed in children, which has great importance in recovery and prevention of hearing loss in children with eustachian tube dysfunction in critical ages of growth development. the location of the vt insertion varies in different studies; the differences are in recovery rates and sequelae of vt insertion. this study is perf...

Memory-augmented neural networks equip a recurrent network with an explicit memory to support tasks that require information storage without interference over long times. A key motivation for such research is perform classic computation tasks, as parsing. However, memory-augmented are notoriously hard train, requiring many backpropagation epochs and lot of data. In this paper, we introduce the ...

conclusions pressure support ventilation, but not spontaneous breathing, induces a significant redistribution of ventilation towards the ventral region. the sensitivity of the support trigger appears to influence the distribution of ventilation only during the early phase of inspiration. background in supine position, pressure support ventilation causes a redistribution of ventilation towards t...
