Stabilized mud block as a substitute for conventional brick block[ ]


The development of many alternative building materials will be of immersive benefit to minimize the impact on the environment pollution. There are few undesirable properties such as loss of strength when saturated with water erosion due to wind or driving rain and poor dimensional stability. Hence a study was conducted to determine the characteristic of stabilized compressed earth block. In this contribution, the stabilized mud block is mixed with 7% of cement 5% cement and 2%. The experiments on the compression and water absorption were made which allow us to determine the characteristics of earth block. Comparisons between the two mixes are discussed. It was found that water absorption is less and dry compressive strength of cement as stabilizer with 7% is higher when compared to cement and lime (5% +2%). Hence the cement with 7% as a stabilizing agent is found to be good compared to other.

Experimental Investigation of Sustainable Concrete Using GGBS and Recycled Coarse Aggregate[ ]


Concrete Consumption is increasing every year. For sustainability reduction of cement and aggregates are necessary. For sustainable con-struction the only way is to reduce the cement and aggregate consumption. Alternative cementations materials like GGBS can be used as a replacement for cement and recycled aggregates for natural aggregates. This study deals with usage of ground granulated blast furnace slag as an alternative for cement and recycled coarse aggregate for natural coarse aggregate. Experimental investigation is carried out with a conventional M25 mix, mixes by replacing with 10 percent, 20 percent, 30 percent, 40 percent and 50 percent of cement with ground granulated blast furnace slag (GGBS). Mix with 60 percent of cement when replaced with 40 percent GGBS gave better performance compared to M25 conventional mix when tested for fresh and mechanical properties. For further study mix was made with 10, 20, 30, 40 and 50 percent replacement of cement with slag and 0, 25, 50, 75 and100 percent replacement of coarse aggregate with 100, 75, 50, 25 and 0 percent recycled coarse aggregate. Its fresh and mechanical properties were then compared with M25 mix. Fresh properties were studied using slump test and compaction factor test. Mechanical properties studied were compressive, flexural and splitting tensile strengths. Mix with GGBS and recycled aggregates gave a satisfactory performance compared to M25 conventional mix.

Mining User Opinions on Different Product Aspects from Online Product Reviews[ ]


Product Manufacturer expects the customer to review their product once they have purchased. Due to the popularity gain in the e-commerce the reviews of the product is also increasing day by day in large number. There is no limitation in writing the reviews by the customer it all depends on the customer satisfaction and their likes. This makes it difficult for a product manufacturer to read the reviews, analyze the opinions and to keep track of product opinions. Thus, we aim to mine the product opinions with respect to its attribute and then rate the aspect. Most of the works before were using document level or sentence level of opinion mining. This work makes use of aspect based opinion mining (phase level or word level). It mainly focuses on mining user opinions on different product aspects from online product reviews and to identify whether the opinions are positive or negative. The methodology we present here will enhance effectiveness of the time efficiency of aspect orientation.

Face Detection based Locker Security System using Raspberry Pi[ ]


In current scenario, bank and locker robberies are frequently happening this means our locker is vulnerable to theft since it has no ulti-mate protection rather than a lock and key. Currently, most of the banks use two keys to open the lockers. One key is with the customer and another key is with the bank manager. This system is having some drawbacks. There is a possibility of losing the key which make the system to be insecure and duplication of keys may lead to unauthorized access of the locker. So in order to overcome that we are introducing Locker Security System based on Face Recognition and GSM (Global System for Mobile) technology, which can be used in Banks, Security Offices and Homes for giving protection to expensive possessions. In this system, only the authorized person can access the valuable things like money, licenses and jewels from locker. Face Recognition is done by using active appearance model algorithm with Bayesian classifier, which is used to identify the persons and verify their identity with the Raspberry Pi processor. RFID (Radio-frequency identification) and GSM technology are combined together for accessing the locker securely. When an authorized person tries to access the locker, the system will generate a one-time password and send to the registered mobile number of that person. If the password entered by him is correct, then only he will be allowed to access the locker. If he does any offensive acts on the locker, it will be sensed by the vibration sensor and the sensor will send the control signal to Raspberry pi processor and it will generate alarm sound.

FORMING OPINOIN VIA TRUSTED FRIENDS IN E-COMMERCE USING SOCIAL NETWORK[ ]


In this dynamic era, online shopping and associated recommendation systems become essential ingredients of web based systems. The global ratings provided by each online portal are not trustworthy, because it is possible to give some level of rating for each product by them. Most of the existing work only considers the ratings at the current time slot. In real life, a user’s opinion evolves over time, since he receives the influence of different opinions sequentially.So we are using a social network for connecting the trusted friends such that shopping through this network provide a trusted rating along with the global rating which provided by the portals. That means we will get multiple ratings from multiple user in a single point of view. To reach these ends we propose a new model, FluidRating which uses fluid dynamics theory to reveal the time-evolvingformulation process of human opinions.Here we compare the user as container such that several containers are connected through pipes which are influence relations such as “persistency”,“persuasiveness” and “forgetting”.So the final decision by the user can take from an analysis based on Global rating, Buyer and Non-buyer trusted friends rating through this social network.

Feasibility Evaluation of Short Time Generation Rescheduling Considering Power System Uncertainties and Generator Ramp Constraints[ ]


Renewable energy penetrations and load fluctuations in the grid pose serious threats of uncertainty in the power system. The existing Lambda Iteration method does not take into account the uncertainties and the generator ramp constraints while scheduling the thermal generators for optimal dispatch of power to reduce the supply demand mismatch that is a common phenomenon in the present power scenario. This paper proposes an algorithm with modification in the lambda iteration method to account for these uncertainties and the generator ramp constraints to achieve short time generation rescheduling. The method is technically feasible and is suitable for high-speed online application due to fast and steady computation time.

Hybrid Buck Boost Converter For Simultaneous DC And AC Applications[ ]


This work proposes a family of hybrid converter topologies which can supply simultaneous dc and ac loads from a single dc input. These topologies are realized by replacing the controlled switch of single-switch boost converters with a voltage-source-inverter bridge network. The resulting hybrid converters require lesser number of switches to provide dc and ac outputs with an increased reliability, resulting from its inherent shoot-through protection in the inverter stage. Such multi outputconverters with better power processing density and reliability can be well suited for systems with simultaneous dc and ac loads, e.g., nanogrids in residential applications. The proposed converter, studied in this paper, is called boost-derived hybrid converter (BDHC) as it is obtained from the conventional boost topology. The steady-state behavior of the BDHC has been studied in this work,and it is compared with conventional designs. A suitable pulse width modulation (PWM) control strategy, based upon unipolar sine-PWM, is described. A DSP-based feedback controller is designed to regulate the dc as well as ac outputs. A 600-W laboratory prototype is used to validate the operation of the converter. The proposed converter is able to supply dc and ac loads at 100 V and 110 V (rms), respectively, from a 48-V dc input. The performance of the converter is demonstrated with inductive and nonlinear loads. The converter exhibits superior cross-regulation properties to dynamic load-change events. The proposed concept has been extended to quadratic boost converters to achieve higher gains.

Design & Simulation Of New Converter Topology For Solar Power Generation System[ ]


A new solar power generation system is composed of a dc/dc power converter and a new seven-level inverter. The dc/dc power converter integrates a dc–dc boost converter and a transformer to convert the output voltage of the solar cell array into two independent voltage sources with multiple relationships. This new seven-level inverter is configured using a DC-DC converters and a full-bridge power converter, connected in cascade. The DC-DC converters converts the two output voltage sources of dc–dc power converter into a three-level dc voltage, and the full-bridge power converter further converts this three-level dc voltage into a seven-level ac voltage. In this way, the proposed solar power generation system generates a sinusoidal output current that is in phase with the utility voltage and is fed into the utility. The salient features of the proposed seven-level inverter are that only seven power electronic switches are used i.e., three switches and three dc sources to generate three level dc voltage and one bridge circuit to convert this three level dc voltage to seven level ac voltage. Where in conventional converter three bridge circuit along with three dc sources are required to generate seven level voltage.

Magnetic Technology In Computers To Reduce Power Consumption[ ]


In the recent years there is a growing demand of power consumption, which is the measure of prosperity. To fulfil this growing energy demand it is to either increase the generation of energy or reduce the energy losses or consumption in the devices. Recently the trend is switching towards the reduction of energy consumption in the devices and also to reduce the size of the components using modern fabrication technology. One of such is the improvement in fabrication technology of magnets leading to the replacement of electronics circuit in chip by Nano-magnets which helps in reducing the power consumed by the electronic circuits. The work on replacement of the electronic circuits by magnets and designing the computer using array of quantum dots was started an era back but due lack in fabrication technology this seemed a difficult task. Now with the help of improved fabrication technology the idea of making computers by using arrays of quantum dots is possible. The computation time taken is slightly more than electronic circuits though the major advantage of reduced power consumption compensates it.

Self-Healing In Electrical Domain[ ]


This paper deals with the survey conducted for self-healing of underground insulation cables for high voltage system. The internal damages in the composites is extremely difficult to detect and also to repair. Therefore the self-healing technique provides a direct re-sponse to its degradation. This can be very useful in challenging environments. This deals with the concept of self-healing during the occurrence of electrical treeing which results in degradation of the material and therefore shorten its service lifetime. Monomers are filled in the microcapsules which are placed in the thickness of the insulation. When electrical treeing occurs, the capsules rupture and the liquid monomer (healing agent) fills the cracks, stopping the progression of electrical treeing. The final process is polymerization of the monomer which occurs when the monomer reacts with the catalyst which is also added to the insulation material. One of the branches of the tree is likely to break the capsule and since all the branches are interconnected, the entire tree fills up with the healing agent. The experimental setup provides the propagation of the phenomenon and also the direct attraction of the tree with the capsule using an optical microscope.

Robust face detection and person recognition using gabor texture and multi block LBP features[ ]


By means of increasing security concerns, surveillance cameras are have an important role in the society and face recognition in mass is gaining more importance than ever.To identify people in unconstrained video, one has to come across at the identity information in multiple frames and the additional dynamic signature. These identity cues including face, body, and motion. The proposed project approach is based on video-data base due to the huge application available for large intra person variation in video and limited information content in still images. Video- data base is to completely encode temporal, pose, and lighting information. In order to make a fully automated system that analyzes the information in face images, there is a need for robust and efficient face detection algorithms. The proposed work is divided into two phases, i.e. Training and testing. In training phase, preprocess the extracted frames which include resize and color conversion. These extracted features are stored in a database. In testing phase, by taking input video and extract the frames followed by preprocessing. For face part detection, from the extracted frame using adaboost approach and extract the features from the detected image. These features are stored using Support Vector Machine (SVM). Finally recognize the person using stored features. The proposed work deals with video based face recognition and person identification, using adaboost technology to extract feature of the person and identification. Also adapting a gabor coefficient filter to get effective results.

Substation Automation system[ ]


Green and sustainable power is the need of the day. With widening supply and demand gap, power management has become one of the most critical areas of concern all over the world. India’s energy consumption is increasing at one of the fastest rates in the world. Hence, we require Substation Automation Systems in the present day substations to efficiently control and deliver power. The main objective is to create a SCADA system for the desired substation. Power automation serving electric supply locations often require special protection against the effects of fault-produced. Protection relays need to function immediately when a faulty condition occurs. This is why Intelligent Electronic Devices (IED’s) are brought in for safe operation of switchyard devices, which can prevent disasters to energy supply and help in human safety. With the introduction of IEC 61850, utility communication will be used for substation automation and also for protection purposes within a substation and between substations. A Substation Automation System (SAS) provides facility to control and monitor all the equipment in the substation locally as well as remotely. A Supervisory Control & Data Acquisition (SCADA) system provides users with a Human Machine Interface (HMI) which can be used for controlling, monitoring and protection of devices. This saves us cost and time. Substations are key components of the power grid, facilitating the efficient transmission and distribution of electricity .Substation automation systems make their control and monitoring possible in real time and help maximize availability, efficiency, reliability, safety and data integration.

Quadcopter for pesticide spraying[ ]


In agricultural fields, the use of pesticides is necessary for better crop yields. The use of aircrafts and drones has become common for carrying out this operation mainly because of its speed and effectiveness in the spraying operation. The disadvantages of manual spraying is that some factors may reduce the yield, or even cause damage (e.g. some crop areas may not be covered in the spraying process, overlapping spraying of crop areas, applying pesticides on the outer edge of the crop). Climatic condition, such as the intensity and direction of the wind while spraying add further complexity to the control problem.An Automated Aerial Pesticide Sprayer is basically Quad copter with pesticide spraying mechanism. This project is to mainly overcome the ill-effects of pesticides on human beings (manual pesticide sprayers) and also to cover larger areas of fields while spraying pesticides in a short span of time when compared to a manual sprayer.

Sea Ice Floe Detection and Classification using Adaptive Clustering[ ]


Detection and classification of sea ice floe is very important for understanding physical process in the polar regions. Important thing is to know the shapes, sizes and spatial distribution of ice floes for understanding the physical process. Several image processing algorithms have been applied to samples of sea ice images in order to extract useful information. In this paper we are proposing a method for detecting and classifying the sea ice floe using adaptive clustering technique, which helps in identifying the classification of images which are done with segmentation that is done by adaptive histogram equalization. In order to improve cluster quality adaptive clustering uses external feedback that improves the execution time. Detect the edge of the ice floes by Canny image edge detection method and extract the features and compare the query image features with knowledge base features and classify the result that is done by SVM classifier. Good experimental results demonstrate the feasibility and effectiveness of the proposed method.

Effect of Tool holder over hang & Feed on Surface roughness in Turning application – an experimental approach[ ]


Manufacturing of machine parts and automobile parts are required to be carried out in various machines. The machining operation is done to convert raw material in to a finished part. Further, to carry out machining operation a cutting tool is to be used having proper tool signature. A tool intended for high production machining process should be amply strong, rigid, and the cutting tool should produce required surface finish on the component which is accepted to the end user, and also convenient to use. The length by which the cutting tool extends from the Tool post or Turret is a variable that can be decided by the machining process. But there is also a certain relationship between product quality in terms of surface roughness and cutting tool over hang. Thus the present paper presents the influence of tool holder over hang and feed rate on the surface roughness while machining Al6061 and fly ash composite. The work material having 15% fly ash and the machining parameters were cutting speed of 300 m/min to 600m/min, feed of 0.05mm/rev to 0.15mm/rev. Tool holder overhang of 35 mm to 65 mm keeping depth of cut of 0.5mm. The experimental results shown increased tool holder overhang of the cutting tool from the carrier body and feed of the cutting tool resulted in higher surface roughness. Hence the feed rate and the cutting tool overhang were considered as a main cutting factor during machining.
