Measurement of surface roughness of any machining process is crucial for obtaining a component or part of the correct size and surface finish in the first instance, in order to minimize the manufacturing cost. In-process monitoring of machining processes based on an estimation of the surface roughness using the cutting parameters is inaccurate. In this investigation, a fuzzy inference system based on an intelligent sensor fusion model has been developed for the purpose of in-process indirect measurement of surface roughness for a machining process. In the proposed technique, measurement of the Speed Force component, Radial Force component, Feed Force component, Vibration, and Acoustic Emission sensor inputs from a turning process have been considered as the inputs. The results have been compared with the surface roughness estimated with a second order regression model using cutting parameters as inputs. The proposed method has shown considerable improvement in the surface roughness estimation in a simulation environment.

In this paper, we have developed a hetero-core structured fiber optic Fabry-Perot (FP) sensor. The hetero-core interface is simply made by fusion splicing two fibers with different core diameters. The hetero-core insertion length plays a role as a FP cavity length. The cavity length could be easily tuned by the insertion length of the hetero-core fiber. Additionally, the sensor has smooth-faced reflector on the hetero-core interface due to fabrication process comprised of cleaving and fusion splicing. Firstly, in order to evaluate the characteristic of the hetero-core structured FP sensor, we carried out the refractive index change experiment with water and glycerin solution. As a result, we can experimentally obtain the refractive index sensing ability of the proposed hetero-core FP sensor. Secondly, we carried out the hydrogen detection experiment by the hetero-core fiber FP sensor which has the 5-nm Pd thin film. We also confirmed that the H2 gas detection by the proposed sensor could be achieved based on the amplitude change in the FP fringe.

Surface Plasmon Resonance (SPR) has become a popular method for the analysis of molecular interaction. There are many different approaches for the detection of SPR, however, the Phase detection method is quite sensitive in that it shows a much sharper change under SPR compared with other alternatives such as intensity and angle interrogation techniques. The SPR phase sensor can detect very low concentration levels of Glycerin that is not possible with intensity and angle based detection methods. Experimental results obtained from Glycerin-Water mixture show that SPR Phase interferometer with continuous phase change allows the detection of very low levels of Glycerin concentrations. Such an improvement in SPR Phase sensor can make it a more suitable option for biomedical applications.

This paper proposes a fast and robust real-time object tracking technique in a ball and beam system following the concept of rotating frame (to be called as rotating ball and beam system). The technique uses a standard contact free video camera which is placed at a static position and allows the sensor to capture the entire dynamic motion of the system. Since the captured image is in the world coordinates, instead of the rotating beam coordinates, the position of the object is easily extracted using either of the two projective transform methods such as Hue, Saturation and Value (HSV) or Hue, Saturation (HS). Experimental results on a prototype ball and beam system demonstrate that performance of HS based object localization, which ignores the light intensity, is better compared with HSV based method.

Using more and more sensors, an increase in complexity and quantity of wiring is the consequence. This can be solved by using wireless sensors which are powered by energy harvesting. For this purpose, thermal energy harvesting by using atmospheric temperature variations is investigated by using a test setup in a climate cabin with a 65 minutes temperature cycle with minimum temperature of -40°C for 6 minutes. The results shown a maximum reached temperature difference is 37.5 K which results in 6 mW electrical power the chosen thermos-electric generator (TEG) produces. Utilizing an energy-harvesting power management unit to the setup results in a maximum electrical energy conversion efficiency of 92% and a maximum electrical storage power in a supercapacitor of 5.5 mW. The overall electrical energy the TEG generates is 8.85 J. The total energy that is stored in the supercapacitor is 7.85 J, which is an overall energy conversion efficiency of 89%. The results of using two identical TEGs parallel in the same thermic setup shows the limitation of this.

Tea taste sensing is a very complex activity usually carried out by industry experts. There have been numerous approaches to develop an electronic tongue in order to automate this process. This paper describes an experimental approach based on electrochemical impedance spectrometry of black tea. The initial experimentation illustrates that the Nyquist plots of the liquid tea display significant differences between the considered various types of black tea. They can easily be categorized into different groups or clusters depending on the real and imaginary impedance at different frequencies as well as their temperature dependencies.

We presented here the findings of linear and nonlinear excitation of an optical fluorescence sensor enhanced with chitosan-based thin films coated on tapered optical fiber for detecting of dinitrobenzene solution compound. The absorbance peak of linear excitation at 441.2 nm shows a small shift to from 540.8 nm to 541.3 nm when 0.003g/ml dinitrobenzene was diluted in acetone. Time resolved fluorescence resulting in decreasing of fluorescence intensities was recorded for both linear and nonlinear excitation. Both showed an agreement of quenching of fluorescence up to 30% of its initial fluorescence due to the free electron transfer from chitosan thin film to the dinitrobenzene. Nonlinear excitation gives more rapid time-resolved florescence after 4 minutes compared to 6 minutes in linear excitation.

Digital color images, in three color channels, are capable of presenting hue, saturation, and intensity perceptions to the human visual system. Improvement on color images quality should therefore be considered to simultaneously enhance all these attributes. An efficient approach was here developed aiming at mitigating the heavy computational burden, in conventional approaches, arising from the need to transform the source color space into an alternative working space. Color correction based on the white-point assumption is first carried out, and then enhancement is derived from an intensity-guided operation that simultaneously improves the contrast and saturation qualities. Experiments were conducted using a collection of real-world images captured under various environment conditions and enhancements were obtained both in subjective viewing and metrics in colorfulness, saturation and contrast.
