U-shaped learning deals with a learner first having the correct hypothesis, then changing it to an incorrect hypothesis and then relearning the correct hypothesis. This phenomenon has been observed by psychologists in various studies of children development. In this survey talk, we will discuss some recent results regarding U-shaped learning and related crtieria.

A compact ultra wideband (UWB) monopole antenna with dual band-notched characteristics is presented. The antenna consists a square radiating patch with L shaped slots on the radiation patchand a U shaped slot as the feedline. By cutting two C-shaped slots in the ground plane, additional resonance is excited and hence much wider impedance bandwidth can produced, especially at the higher band, wh...

To meet the stated climate change targets and to ensure capability of meeting current future energy demands, there is an urgent need develop renewable sources, such as geothermal systems. If systems are be cost-efficient enjoy public confidence, it essential that they designed installed in accordance with prevailing site-specific conditions. A thorough understanding thermal behaviour surroundin...
