Two new cell structures for optical compensated bend were proposed. There are two groups of slit electrodes, which are driven by two different signals corresponding to the entire electrode as common electrode. The transmittance was enhanced without increasing the response time and light leakage. Compared with the traditional OCB mode, the increment of the transmittance of each kind is about 90% and 30%.

In this paper, a micromachined millimeter-wave end-gap band-pass filter (BPF) is presented. The millimeter-wave BPF is designed using 3D design software, Zeland IE3D with the center frequency of 60 GHz, band width of 3 GHz, ripple of 1㏈ and insertion loss of 2.5dB. This type of micromachined BPF can be used in millimeter-wave circuit.

The 6- inch electrowetting display (EWD) can be successfully developed by ink jet printing (IJP) technique. Due to the drop-on-demand characteristic of IJP technology, colored oil can be precisely dosed into the unit pixel. Here, we present the active matrix EWD in this article. By adopting this technique to dose different colored oils, single layer Multi-color EWD without adopting color filter can be achieved in the future.

The Sembilan Archipelago is famous for its great biodiversity, in which the humphead wrasse (Cheilinus undulatus) (locally named Napoleon fish) is the primary commodity (economically important), and currently, the environmental degradation occurs due to anthropogenic activities. This study aimed to examine the eco-environmental parameters and assess their influence on the abundance of humphead wrasse and other coral reef fish compositions in the Sembilan Archipelago. Direct field monitoring was performed using a visual census throughout an approximately one km transect. Coral cover data collection and assessment were also carried out. A coastal water quality index (CWQI) was used to assess the water quality status. Furthermore, statistical-based analyses [hierarchical clustering, Pearson's correlation, principal component analysis (PCA), and canonical correspondence analysis (CCA)] were performed to examine the correlation between eco-environmental parameters. The Napoleon fish was only found at stations 1 and 2, with a density of about 3.8 Ind/ha, aligning with the dominant composition of the family Serranidae (covering more than 15% of the total community) and coinciding with the higher coral mortality and lower reef fish abundance. The coral reef conditions were generally ideal for supporting marine life, with a living coral percentage of about > 50% in all stations. Based on CWQI, the study area is categorized as good and excellent water quality. Of the 60 parameter values examined, the phytoplankton abundance, Napoleon fish, and temperature are highly correlated, with a correlation coefficient value greater than 0.7, and statistically significant (F < 0.05). Although the adaptation of reef fish to water quality parameters varies greatly, the most influential parameters in shaping their composition in the study area are living corals, nitrites, ammonia, larval abundance, and temperature.
