The metallic photonic crystals (MPC) in gallium nitride (GaN) light-emitting diodes (LED) can exhibit photonic crystal band gaps and surface plasmon resonance (SPR) phenomena. The simulation results are presented by using finite-different time-domain (FDTD) method. We designed the two-dimensional (2D) triangular arrays of metallic photonic crystals that are located on the p-GaN surface, ITO surface,...
Initial experimental work has demonstrated that x-ray bombardment of organic-based photocells (specifically P3HT:PCBM-based) leads to a reduction in the open-circuit voltage (Voc) without apparent change in the carrier relaxation time. The variation of Voc was suggested to be due to the injection and trapping of holes near the anode, which resulted in a decrease in the built-in potential. We have...
This work develops an efficiently low-complexity method to compute a 2-dimensional inverse integer transform in H.264/AVC. First, the end-of-block points in 4 × 4 and 8 × 8 blocks are computed and then used to select one of 7 and 15 operation modes for each block, respectively. Second, the computation order of row-after-column and column-after-row used for 1-dimensional inverse integer transforms...
We developed an intelligent agent, RoboLeader, that could assist human operators in route planning for a team of ground robots. We compared the operators' target detection performance in the 4-robot and 8-robot conditions. Results showed that the participants detected significantly less targets and had significantly worse situation awareness when there were 8 robots compared to the 4-robot condition...
The cell process is the main part of thin-film transistor liquid-crystal display (TFT-LCD), and can be divided into front-end process and back-end process. Since the production machines of the cell process are the critical resources, maximizing the machine utilization and minimizing the loss of capacity become the major concern for production planning. This research studies the scheduling of machine...
This study investigated the performance and workload of the combined position of gunner and robotics operator in a simulated military multitasking environment. Specifically, we investigated how aided target recognition (AiTR) capabilities for the gunnery task with imperfect reliability (false-alarm-prone vs. miss-prone) might affect the concurrent robotics and communication tasks. Additionally, we...
We simulated a military mounted environment and examined the performance of the combined position of gunner and robotics operator and how aided target recognition (AiTR) capabilities (delivered either through tactile or tactile + visual cueing) for the gunnery task might benefit the concurrent robotics and communication tasks. Results showed that participants' teleoperation task improved significantly...
