...le producing a signal to noise ratio of > 4.0 for detection of ~ 1,000, R. typhi cells. Titration experiments conducted in buffer revealed a limit of detection between 100 and 1,000 R. typhi cells per ml. The Rt-18R aptamer detected only one band at ~ 84 kD in R. typhi lysates on aptamer Western blots. While the homogeneous Rt-18R fluorescent sandwich aptamer-magnetic bead assay did not cross-react with comparable concentrations of E...

ROBUST MULTIMODAL FACE RECOGNITION WITH PRE-PROCESSED KINECT RGB-D IMAGES
...epth maps have holes and noise induced from camera
sensors, therefore we process them to remove these distortions and then we apply the face recognition algorithm.
Experimental results reveal that the accuracy of face recognition can be increased by combining RGB and depth

determined through analysis of variance approach. The results showed that the penetration depth and bead width
were increased with increase in current and decrease with increase in torch speed. It was concluded that the arc
current is the significant factor for both the response parameters while torch angle is significant only for bead width.

STUDY OF OCCUPATIONAL HEALTH SAFETY IN STEEL RE-ROLLING MILL WITH REFERENCE TO HIGH NOISE LEVEL AND TEMPERATURE
...o assess the exposure to noise and temperature in a steel re- rolling mill. The measured noise and temperature values were then compared with international standards set by Occupational Safety and Health Administration (OSHA). Our results indicate that temperature level was high at two places of the mill i.e. furnace and re-rolling mill sections with the average value of 67 °C and 39°C respectively, which exceeds OSH...

COMPARATIVE STUDY OF RELAY PROTOCOLS USING SIMULATION
...ious ranges of signal-to-noise ratio (SNR) probabilities. A three node system i.e. source, relay and destination, placed on the edges of equilateral triangle, has been proposed using Maximal ratio Combiner (MRC) method by combining signals from source and relay at destination point. The transmission path is modeled as a frequency non-selective Rayleigh fading in the presence of additive white Gaussian noise

DYNAMIC MODELING AND CONTROLLER DESIGN FOR NUCLEAR POWER PLANT
...d in order to reduce the noise sensitivity. The problems of noise sensitivity and poor output error dynamics are addressed and a multi-objective optimization problem is solved using LMI (Linear Matrix Inequalities) formulation. Fast output feedback gains are computed using LMI tool for MATLAB. An advanced fast output sampling controller is evaluated for power maneuvering from 270 MWth to 310 MWth on the n...

This entails expediting the decision-making process as well as to instill intelligence in the approach to reduce subjectivity to a greater extent. To harness the high computational power offered by commodity graphics processing units (GPU) and accomplish the decision-making in real-time has gained traction in a gamut of recent biomedical applications. This review a...

The aim of this research is to integrate the signal processing technique Discrete Wavelet Transform (DWT) with different versions of Mann-Kendall (MK) trend tests for investigating the dominant climate systems characterizing the long-term time-series of the two most important meteorological parameters: mean air temperature (oC) and total rainfall (mm) for the different stations lying in the upper Indus River basin of ...
Effects of Flight Disturbance on Bird Communities at Airports: Predatory Birds Rise to the Challenge

...fects of aircraft flight noise disturbance on airport bird communities, the composition and diversity of airport bird communities on flight and non-flight days were investigated using a line transect sampling method at the eastern airport of Hebei Province from June to August, 2019. In total, 36 species belonging to 11 orders and 22 families of birds were recorded. Disturbances such as noise from aircraft flights affected th...
