Active harmonic filtering using current-controlled, grid-connected DG units with closed-loop power control
Renewable energy sources such as solar, wind are becoming more popular to generate power. These renewable energy based power generation systems generate DC power output. An inverter is needed to convert DC power from renewable energy sources into AC power. These renewable energy sources are connected to the grid through interfacing converters which supply active and reactive powers to the main grid. Inverters are either be connected in standalone or in grid connected mode. In the case of grid-connected mode, the output voltage and frequency of inverter should be same as grid voltage and frequency. If loads connected to the grid are non-linear in nature, then it can introduce power quality problems such as harmonic distortions in grid voltage.

Bio-metric authentication using non-expanded inverted share image visual cryptography
A biometric authentication system operates by acquiring raw biometric data from a subject e.g., fingerprint and iris images. This original raw data is stored in the central database. Preserving the privacy of this digital biometric data has become very important. Visual cryptography can be applied to securing this information. The proposed work preserves the privacy fingerprint and iris-based authentication using Inverted Share image Visual Cryptography (ISVC). In ISVC, we invert one share image and stack it with another shared image to obtain the extra confidential data that can be used for authentication. In traditional visual cryptography, the size of the recovered image is expanded because of pixel expansion during encryption. This also leads to recovered image distortion. Therefore, the proposed scheme combines a non-expanded scheme with the extra ability to hide biometric data, such as fingerprint and iris image, in some cover image to maintain privacy. This will also solve the pixel expansion as seen in traditional visual cryptography

Flexural retrofitting of geopolymer RC beam with ferrocement laminates
The present paper deals with the experimental investigation carried out to study the effect of Ferrocement laminates on the strengthening of Geopolymer reinforced concrete rectangular beams. Various rehabilitation techniques have been proposed yet but among these techniques, external strengthening provides a practical and cost-effective solution when compared to other repair methods. Reinforced concrete components are formed to exhibit distress and get deteoriated due to various factors and hence need strengthening. Ferro cement is most commonly used as retrofitting material due to their easy availability durability and their property of being cast to any shape without needing significant formwork. In this investigation, we examined the performance of R.C. beam strengthened by Ferro cement, 15 beams of the rectangular cross-section were cast using m20 grade concrete and were tested for collapse load. Further beams were stressed up to 70%, 80% &90% respectively. The investigation shows that up to 80% of the pre-damaged beams can be strengthened using Ferro cement. The need for the construction industry to look for a reliable and cheaper strengthening component for reinforced concrete structure has led to the usage of Ferrocement which proves to be a promising solution. In this paper, reinforced concrete beams strengthened with Ferrocement laminates attached to the soffit of the beams and control beam are observed through experimental study. Experimental results show that the strengthened beams and control beam are observed through experimental study. Experimental results show that the strengthened beams have increased ultimate moment capacity and also, it shows better serviceability performances in terms crack control and deflection.

Experimental investigation on flexural behaviour of various steel fibre reinforced concrete beam
The performance of concrete made with commercially available steel fibres has been investigated. In this study examines the flexural strength of concrete with two different types of steel fibre, short crimped of length 15 mm, another of long hooked ends of length 30 mm and were used in the present study. The overall volume fractions of steel fibres were restricted to 1 percent by the volume of concrete. M25 grade of concrete was used to cast the specimens. Reinforced concrete beams of 1.5 m length and 100 x 150 mm in cross-section were cast with different percentages of micro and macro steel fibres and the specimens were tested under single point loading after 28 days of curing. The results are to be compared between conventional concrete to fibre reinforced concrete.

Automatic wall painting robot
The painting chemicals are found very much harmful to human painters which were causes the problem to eyes and respiratory system of a human being. Also, the nature of the painting process that requires habitual work and hand rising makes it boring, time and effort consuming. To overcome these problems the proposed system has developed. The belt drive mechanism based systems used to drive the roller up, down, left and right for painting on the wall. And the sensor is using to detect the presence of wall

Development of village as a smart village –A case study on Ponkurichi village
“The Future of India lies in its villages” Mahatma Gandhiji. A smart village knows about its citizen, available resources, applicable services, and schemes. It knows what it needs and when it needs. The concept of the smart village makes the villages self-sufficient in respect of their needs. This study was carried out with the main focus to develop the Ponkurichi village into a smart village. The household survey was carried out throughout the Ponkurichi village to understand the needs of the residents and to provide the basic amenities like educational facilities, health care center, rainwater harvesting, transportation facilities, agriculture, water facilities, waste disposal, recreation area, etc. result of the survey and other secondary data collection, the immediate needs and other infrastructural requirements required for the Ponkurichi village are identified. The future land use pattern of the Ponkurichi village is proposed with the recommendations of basic infrastructural facilities to the Ponkurichi village to develop it into a smart village.
