This paper introduces a fuzzy sensor validation and fusion methodology and applies it to sensor data from a gas turbine power plant. The FUSVAF (Fuzzy Sensor Validation and Fusion) algorithm tackles two problems: (1) It filters out noise from measurements provided as input to a gas turbine controller to maximize power plant performance. (2) It compensates for sensor failure to allow the power p...

The effect of diet on the lethality of 1, 2-dimethylhydrazine (DMH) injec tions was investigated using Swiss mice. Mortality was highest when mice were fed a nutrient-dilutealfhigh-fat diet, was intermediate with a nutrientdilutealflow-fat diet and was lowest with laboratory chow. Wheat bran was not protective. Mice developed tolerance to DMH after receiving several injections of progressively ...

BACKGROUND Whether Folic acid is a potential drug that may prevent the progression of colorectal carcinoma and when to use are important healthy issues we focus on. Our study is to examine the effect of folic acid on the development of the CRC and the optimal time folic acid should be provided in a mouse-ICR model induced by 1, 2-Dimethylhydrazine. Also, we investigated the gene expression prof...

Morphology transformation and crystal growth strategies of metal oxide semiconductors are still extensively studied in material science recently, because the morphology crystallinity significantly affect physicochemical characteristics nanomaterials. However, understanding changes ?-MoO3 induced by annealing is a challenge. Herein, nanostructure transition temperature carefully investigated via...

Wang). ted equally to this Abstract Compared with conventional Ohmic-contact nanosensors, Schottky-contact has been introduced as a fundamentally new design for much enhanced sensitivity and improved responsive time of onedimensional nanostructure based sensors. Here we demonstrate ZnO micro/nanowire sensors for hydrogen (H2)...

A novel pressure sensor is investigated numerically. Operation of this sensor is determined by mechanical stresses and heat exchange. Estimation of deformations and heat transfer was done using programs ANSYS and ANSYS CFX. Numerical model was calibrated to fit experimental results. Conclusions about significance of heat exchange, thermal stresses and overall action of sensor were made. 1. Gene...

5-fluorouracil is a widely used anticancer drug with many side effects on humans, and hence its analysis in biological samples is very important. Accordingly, a novel sensitive electrochemical approach was fabricated by incorporating graphene quantum dots (GCD) and 1-butylpyridinium bromide (BPBr) in the formulation of a carbon paste electrode (GQD/BPBr/CPE). The GQD was synthesized and charact...

In this study, an organic-inorganic semiconductor gas sensor was fabricated to detect ammonia gas. An inorganic semiconductor was a zinc oxide (ZnO) nanowire array produced by atomic layer deposition (ALD) while an organic material was a p-type semiconductor, poly(3-hexylthiophene) (P3HT). P3HT was suitable for the gas sensing application due to its high hole mobility, good stability, and good ...

One concern in using photonic band-gap fiber (PBGF) as a gas sensor is the response time. In this type of the gas sensors, response time is the time required for gas to diffuse into the hollow-core. So considering a large hollow-core PBGF (HC-PBGF), the response time can be significantly reduced. But in the large HC-PBGF, the fundamental issue is the presence of higher order modes (HOMs). Somet...
