Title: Sustainable irrigation through dynamically and mechanically of smart ramp pump water system
Abstract: Nowday the use of ramp pumps become more popular because the system fulfil the concept of sustainability. The basic principle of smart ramp pumps is to use a large amount of water falling pressurise a short distance, to pump a small amount of water by water hammer effect then pumping the water to a higher point at agricultural area. The development of ramp pump is consists of Poly Vinyl Chloride (PVC) conveyance piping, T-joints, threat joints and control valve which connected with smart reservoir system. Materials and Methods: Experiments were conducted with two variable water resources in common height between agricultural area with river stream which area two (2) feet. Results: Observation revealed that the ramp pump performance are depend on the height of water resource, height of delivery pipe, size of pipe and size of ramp pump. Estimation of 15.55 litres water is pumped to the delivery point while the wasted water that flows back into water stream is about 194.45 litres, mean that 92.59% from overall intake of water flow. While the percentage of 7.41% water is fed into conveyance system which suitable to irrigate the small farm area. Although the pumped water volume is low mechanically, but the amount of water is pumped continuously and the ramp pump operated sustainably without any fuel or electricity. Some adjustment for making ramp pump work at flat flow river stream dynamically, the pressurise delivery piping is designed which base on reducing diameter sizes of pump inlet. Conclusion: This technique on natural ramp pump application was comply in nowdays sustainable concept in agriculture. The water that naturally catch from water stream can be freely to be irrigate in plantation area that avoiding to depend on power electricity.

Title: Intelligent Hand-held Robotics for Microsurgery
Abstract: Precision, robustness, dexterity, and intelligence are the design indices for current generation surgical robotics. To augment the required precision and dexterity into microsurgical work-flow, hand-held robotic instruments are developed to compensate physiological tremor in real-time. The active compensation is challenging due to the time-varying unknown delay introduced by hardware (sensors) and software (causal linear filters) that adversely affects the device real-time performance. The current techniques for 3D tip position control rely on modeling and canceling the tremor in 3-axes (x, y, z) separately. Our recent findings show significant correlations in tremor across the three dimensions (x, y, z) and the grip force (f). This talk will first introduce the challenges and present our research efforts on multi-dimensional (3D and 4D) tremor modeling that show improved performance.
