We demonstrate an optical Fabry-Perot interferometer fiber tip sensor based on an etched end of multimode fiber filled with ultraviolet adhesive. The fiber device is miniature and robust, in a convenient reflection mode of operation, has a high temperature sensitivity of 213 pm/°C within the range from 55 to 85°C, a good refractive index sensitivity of ∼−73.54 nm/RIU (refractive index unit) within...
As the neuro-fuzzy system is based on a feed forward network structure, it cannot effectively cope with dynamic processes such as space heating systems for the built environment. To overcome this problem, an improved version of the hybrid system is developed and presented in this paper. This system has self-feedback loops for the output that can model the dynamical behavior of the process. The developed...
Geyser-1 is a MIPS CPU which provides a fine-grained run-time power gating (PG) controlled by instructions. Unlike traditional PGs, it uses special standard cells in which the virtual ground (VGND) is separated from the real ground, and a certain number of the sleep transistors are inserted for quick power shut-down and wake-up. In Geyser-1, the fine-grained run-time PG is applied to computational...
Inferential sensors are used to infer the critical control variables that are otherwise difficult, if not impossible, to measure in broad range of engineering fields. All inferential sensors are based on an inferential modelling module that represents the dynamics between the inputs and the outputs. Two commonly used artificial intelligence based approaches for the development of the inferential modelling...
