Corrosion is one of the most universal major defects in structured systems and can cause many safety risks if proper treatment and maintenance is not done. Robotic systems such as drones with integrated machine vision modules for real-time corrosion monitoring have the potential to significantly decrease the inspection time, unreliability of inspection procedures. This study investigates the use of bag of key points method for visual categorization of corroded and non-corroded images. The notion behind bag of key points method is that an image can be represented as a histogram that counts the occurrences of visual words. These visual words are obtained by clustering feature vectors of key points in the training images. We have used SIFT (Scale Invariant Feature Transform) descriptors to represent key points and used the following algorithms for classification after clustering the descriptors and generating features of fixed size: SVM, Decision Tree, Random Forest, KNN, ANN. We present results for corrosion identification problem and the results reveal that the method proposed is robust and produces good performance measures.
In this study, we present a scheme that combines LSB (Least Significant Bit) DWT (Discrete Wavelet Transform) watermarking techniques. Data compression has rapidly evolved due to variable mobile terminals and the vast amount of images and video. It is necessary to prevent access to and maintain the confidentiality of data. LSB and wavelet watermarking methods have arisen to address this need. However, unlike the LSB insertion method, the proposed scheme is effective against several attacks. The scheme first inserts a watermark using LSB in a test image, and 3-level DWT decomposition is implemented for robustness and security. We measured the Mean Squared Error (MSE) and Peak Signal to Noise Ratio (PSNR) to validate the scheme and acquired reasonable results. This study highlights the hierarchical structure of the LSB and wavelet-based watermarking technique.
The savings in power electricity consumption should be done in order to be enjoyed by many people. Method lowering the location of the point of the lamp can increase the intensity of illumination and can increase the ability of the power of view from the eye. The length decreases the lamp point depending on the size of the subject anthropometry stood up hands grasping. From 6 lamps TL2x18 watt which mounted, generating intensity of illumination about 336.43 lux on the decline throughout the 90 cm and 344 luces along 99 cm. In Table 1 it appears that the intensity of illumination 344 lux and 336.43 lux can see with bright the letter height 2.2 cm and a width of 1 cm as far as 488 cm. This method can be used anywhere and can help in saving energy.
Recently there has been an increasing demand of an automated system for animal species identification, where it needs a perfect good knowledge, understanding of the nature under vision and proper efficient system design. Embedded systems nowadays are offering a brilliant solution. Based on nature of economic and feasibility of advanced, embedded technology is chosen. This paper proposes a design of real-time portable bioacoustics species identification system. It contains two major correlated modules apart, the identification module and the system control module. The identification module is to be implemented in FPGA hardware to achieve species identification process while the system control module will manage and control the entire system. The proposed system is a combination of hardware, software development and operating system customization. It is designed to be decentralize, therefore the need of any server is eliminated. It can be placed anywhere, can be viewed and accessed from anywhere through a web server built-in.
Effects of quarry dust and polypropylene fiber on compaction properties, shear strength parameters, and California bearing ratio (CBR) of a fly ash have been discussed in this paper. Quarry dust was added to a fly ash from 0 to 60% at an increment of 10%, compaction and soaked CBR tests were conducted on fly ash-quarry dust mixes and the optimum percentage of quarry dust was found out to be 40%. Polypropylene fiber was added to fly ash stabilized with optimum percentage of quarry dust, from 0 to 1.5% at an increment of 0.25%. Compaction, shear strength and soaked CBR tests were conducted on fly ash-quarry dust-polypropylene fiber mixes. From the test results the optimum percentage of polypropylene fiber was found out to be 1%. At the optimum percentage addition of quarry dust and polypropylene fiber there is slight decrease in maximum dry density and optimum moisture content, 28% increase in cohesion, 45% increase in angle of internal friction, and 597% increase in soaked CBR of the fly ash.
