    Abstract: Electricity is one of the most important source of energy in our everyday lives. We use it every day in different situations and circumstances. However, it is also the most used and most expensive energy that we always use. This study will determine which region in the Philippines consumed the most and least electricity. It will also study the rela... Show More

    Abstract: Any machine-tool or manufacturing process designed by engineers is not as excellent as plants, animals or processes occurring in natural surroundings, which have been designed by The NATURE in evolution process. The bridge between solutions occurring in natural surroundings and technique create the BIONIC. The bionic (from Greece words “bios – life... Show More

    Abstract: Reinforced concrete (RC) panels are widely used in the prevention and control of rockfall disasters in mountainous areas. In order to avoid the rigid damage caused by rockfalls that directly impact RC panels, the energy dissipation layer is often added to cushion the impact of rockfalls. In order to study the dynamic response of RC panels to differ... Show More

    Abstract: Aiming at the crack damage of concrete in GFRP tubular concrete column, a method based on piezoelectric wave method was developed to monitor the crack damage. By transmitting and receiving stress waves from a pair of piezoelectric ceramic sensors embedded in GFRP tubular concrete, the damage degree of GFRP tubular concrete columns was evaluated by ...
