Hypoplasia is a defect of the teeth caused by defective enamel matrix formation. It is classified into several categories based on its root cause and the region of defect. In this study, we discuss the hypoplasia occurring in the enamel part of the teeth. Enamel hypoplasia occurring due to environmental factors is called Dental Fluorosis and which occurs due to hereditary problems is called Amelogenesis Imperfecta. Both AI and DF can be cured effectively if they are detected in the early stages of formation. The appearance of stains is similar in both cases which results in a diagnostic dilemma for the dentists. Currently, due to the technological advancements, different radiographs such as panoramic and periapical radiographs are used for diagnosis. Radiographs can provide accurate results, but the frequent exposure to radiation can result in some deterministic and stochastic health effects like cell killing, damage of tissues. Also, this process can be time-consuming for screening a large number of patients for epidemiological surveys.

Pin joints are structural elements which are extensively used in mechanical and structural design. Friction plays a significant role in fastener joints in redistributing the stress and there by affecting fatigue life. In the current this thesis lug joint with rigid and interference fit is considered¬¬. It is well known that as the load is increased on the interface, localised relative slip is initiated between the pin and the lug. This initiated slip is due to the shear forces on parts of interface overcoming the local frictional forces. Therefore the region of slip spreads non- linearly with the applied load. Slip amplitude for interference fit with infinite friction is determined by inverse technique. This slip region leads to high stress concentration at the edge of the hole influence difficulties in fretting damage, crack initiation crack growth life.

In this survey paper we can see the comparison of density and temperature for petrol, diesel and crude oil,. Density is the mass of any material per unit volume. Most of the materials have lower density of liquid than the solid but this is not true in all condition. Water has a higher density in the liquid state than the solid and the temperature is related to the average kinetic energy of the atoms or molecules within the substance and it is proved that volume is directly proportional to temperature by the equation PV=nRT.

Roads are vital for the transport of the goods and passengers. So roads should be durable and strong. The roads should be worthy for its construction cost. And also it should be suitable for all the weather condition prevailed in India. But the grade of bitumen produced in India without admixtures are not durable and strong. The next problem we are facing the waste management. By analysing these two issues, we discussed the addition of waste materials as an additive for improving the bitumen quality and strength. The major grade of bitumen used in India is 60/70. So we choose the same grade of bitumen for proceeding our project. We are using poly propylene, rice husk ash and the combination of glass powder and crumb rubber. These additives are added in different proportion and check the durability, penetration, stability, ductility, flow value. The aggregates and filler are taken as per the IRC recommendation. So by this experimental study we are scoping not only to improve the quality of Dense Bitumen Macadam (DBM) but also help in waste management.

In the current engineering scenario, brass and copper alloys are important class of materials suitable for journal bearing applications. Owing to the environmental laws and the increase in cost of copper, it is found necessary to replace the copper based materials with alternate materials. Through the literature review it is found that ZA 27 is a suitable alternative. The wear rate has been reported to be very less when compared with copper based materials and it has been found to posses higher tensile strength, lower specific weight and easy machinability characteristics. Moreover, it has been established that the working life is four to five times longer than that of phosphor bronze. Nano lubricants are recently being used in order to improve further the tribological characteristics of bearings. A nano lubricant is a new kind of engineering lubricant made of nanoparticles, dispersant and base lubricant. Thus a lubricant with both the combined properties of both the liquid and solid can be obtained. The concept behind the use of nano lubricant is that the liquid lubricant provides damping and low friction, and the nano particle acting as a solid provides load supporting strength. In this paper, the tribological characteristics of ZA 27 alloy is proposed to be studied under dry condition, lubricated condition and when lubricated with nano lubricant. Sliding wear tests are to be performed using a pin-on-disc apparatus under various conditions of load and sliding speed.

Leaf spots are round blemishes found on the leaves of many species of plants, mostly caused by parasitic fungi or bacteria. A typical spot is “zona”, meaning it has a definite edge and often has a darker border. When lots of spots are present, they can grow together and become blight or a blotch. Fungal spots are usually round or free-form in shape. In most cases, leaf spots are considered to be only a cosmetic problem, but they can have economic effects on nurseries or in floriculture. Recognition of plant leaf diseases along some automatic methods is useful as it decrease a huge effort of observing in large farms, and at initial phase itself it identify the signs of diseases. Plant leaf disease detection and identification includes the stages like image acquisition, image pre-processing, Image segmentation, feature extraction and classification.

This system actually finds out which consumer make tapping before the meter and use electricity without pay. This present the model of STATCOM which controllers the rotor angle deviation, voltage stability, transient stability for the improvement of power system stability. The development of the Morden power system has led to increase the complexity in the study of power system and also present new challenges to power system. The stability plays an important role to ensure the stable operation of power system in the occurrence of large disturbances and faults. The role of STATCOM will be mitigate the voltage problem like voltage sag, voltage swell which are generally occurs in power system during high voltage and low voltage condition. A power system network is considered which is simulated in phase simulation method and the network is simulated in 3 steps i.e. with and without STATCOM and with PSS. When the load increases suddenly the system has been disturbed so for greater performance STATCOM will be used

Surface Acoustic Wave (SAW) technology can be applied to create highly sensitive biosensors due to its extreme sensitivity to surface perturbation. The velocity of an acoustic wave depends upon the mass, density and stiffness of the piezoelectric substrate. The binding of antigens with antibodies, when immobilized in the path of the traveling wave, changes the mass of the biolayer. The mass loading effect perturbs the surface boundary which changes the velocity of the wave and consequently shifts the frequency of the traveling SAW. With a pair of transmitting and receiving Inter-Digitated Transducers (IDT), high frequency SAWs can be generated through radio frequency interrogation at the free surface of piezoelectric material. In the future, bio-molecule immobilization and optimization of the sensors are necessary to develop fully functional devices.

Translucent concrete is an integral part of transparent architecture and is an active research area in these days. The light transmitting media used are plastic or glass optical fibres, or epoxy resin. This media must run through the thickness of the wall so that as light strikes outer face of wall, inner face gets illuminated. This paper shows the construction of light transmitting concrete using plastic optical fibre (POF) and epoxy resin, and compares the parameters of light transmitting concrete with that of conventional concrete. Average 28 day compressive strength of conventional concrete block is found to be 24.22 kN/mm2. When using 1 to 4% of plastic optical fibre, the compressive strengths are found to be varying from 25.26 kN/mm2 to 22.82kN/mm2 with light transmitting ability varying from 40 lux to 122 lux. In case of epoxy resin block, translucency test was conducted both under laboratory and on field. For 0.5% and 1.8% epoxy used, light transmissivity under laboratory condition are found to be 320 lux and 880 lux respectively. On the other hand, light transmissivity in the field, under sun, for 0.5% and 1.8% epoxy used, are found to be 880 lux and 1396 lux respectively. The paper shows that the light transparent ability of these blocks can be utilized in the green building concept, where aim is to reduce negative environmental impact. Also, the substantial increase in the illuminance of translucent concrete, when using epoxy resin, is a promising result towards its use in interior design with demand for good visual acuity.

Jute fiber is natural resources which overcome this demand. In this analysis some amount of Jute fiber (0.5%, 1% and 1.5%) are added on the concrete. Different cubes were casted and gone through compressive strength test on 3rd, 7th and 28th day. On 7th day of casted 1.5% OJFRC possessed the least compressive strength; the addition of 0.5% jute gave the best result.

I. INTRODUCTION In India more than 24 million pieces of cattle hides, 22 million of buffalo hides, 106 million of goat skins and 37 million of sheep skins are processed in about 1600 tanneries. Approximately 2 lakhs tones of solid waste are generated annually from leather industry. In that around 110kgs of hairs are generated around 1- metric tons of raw hides/skins and this is utilised as a low value end products like painting brushes and woollen making etc.. The ultimate aim of this research is to develop dye fixatives from hairs which are generated in the unhairing operation. The leather manufacture is one of the oldest technologies. Its empirical development is shrouded in the antiquity of man’s history. Higher literacy, Fashion and improved economy of people brought in their wake inventions oriented to make life easier and fashionable.Coloring leathers intended to improve its aesthetic appeal and them sartiggy fashion demands necessarily results in increased sales value of the commodity, the ultimate goal of all technology.

Automated Warehouse Robots are the warehouse robots that are used for transporting products from source to destination in a warehouse. The present paper provides an overview of the literature that were surveyed and published in different papers over the past few years. A comprehensive explanation of the present state of the warehouse robots is provided with a varied range of applications such as travel time estimation, collision detection, product identification etc. First the robot identifies the product. Then using a suitable optimal path, it transports the product from the source to its respective assigned shelves. This process goes on till the robot transports all the products from the source to respective shelves assigned to it. But due to increasing demands in orders of products, a new model which is more dynamic should be developed to decrease the computation time for transporting products from source to destination in a warehouse and also decrease collisions. This is a literature survey where we are automating the warehouse robots.

In the present study an experimental investigation was carried out to determine the effect of grain refiner (Al-1Ti-3B) and or modifier (Al-10Sr) on the microstructure, hardness, tensile properties, impact strength and fracture toughness of near eutectic (Al-10Si) Al-Si alloy. The microstructures and fractured surfaces of tensile test specimens of Al-10Si alloy before and after melt treatment are characterized by optical metallurgical microscope /SEM analysis. The results suggest that, improvement in mechanical properties, fracture toughness and strength of Al-10Si alloy was observed with the addition of (Al-1Ti-3B) grain refiner and or (Al-10Sr) modifier when compared to the as cast condition.However, maximum improvement in mechanical properties and fracture toughness were observed with the combined addition of grain refiner and modifier to Al-10Si alloy.

Sustaining available resources is the most important issue faced globally. Increase in the population, urbanization and shortage of water due to less rainfall makes it difficult to provide fair distribution of water resource in real time. To solve this problem, we need an efficient system that provides better monitoring and controlling the consumption of water. Idea of IoT is used for uninterrupted monitoring and tracking of water consumption using Wi-Fi/LAN. Server collects readings of sensors showing the usage of water at every outlet through Wi-Fi/LAN. Users can continuously track the water usage in mobile application. The application can retrieve data stored in cloud and display it to users in a better format. Same application can be used to notify users if their water consumption exceeds a predefined range. This automation can help users to efficiently monitor the usage and keep track of the bills. Unknown leakage in distribution pipe is a major issue that adds up to wastage of water. Wireless Sensor Network Consisting of Water flow sensors can be used for leakage detection in pipes. Proposed system aims at notifying respective authorities whenever the leakage is detected so that immediate actions can be taken.
