This paper presents the design of a subarray module for the implementation of phased array of antennas at 38GHz. In particular, two antenna ports are created to provide the possibility of implementing self-sufficient independent beam-forming networks for the transmitting and receiving systems by embedding a circulator. The radiation pattern of the module is properly designed to avoid the appearance...
The strong momentum of key-value store applications drives the commercialization of key-value-specific hard disk drives. To achieve higher degree of performance, the specific flash-based solid state drives would be also commercialized for key-value store applications in the foreseeable future. However, the existing fixed-sized management strategies of flash-based devices would potentially result in...
Vessel-source air pollution may have a major impact on the marine environment and ecosystem. In this study, a method based on vessel activity intensity was adopted to estimate the emission of air pollutants generated by the consumption of fuel oils from merchant vessels in the Port of Kaohsiung in 2013. The vessel activities were determined by using the vessel automatic identification system (AIS)...
