Renewable energy resources (RES) are being increasingly connected in distribution systems utilizing power electronic converters. This paper presents a novel control strategy for achieving maximum benefits from these grid -interfacing inverters when installed in 3-phase 4-wire distribution systems. The inverter is controlled to perform as a multi-function device by incorporating active power filter functionality. The inverter can thus be utilized as power converter to inject power generated from RES to the grid, and as a shunt APF to compensate current unbalance, load current harmonics, load reactive power demand and load neutral current. This new control concept is demonstrated with extensive MATLA B/Simulation.

Social Media is growing dynamically, but in academics social media is considered to be the deteriorating agent. Social Media has deep rooted in almost all industries including Higher education and have been adopted it. Social Media has become a Buzz word among the people in the society due to its immense and pool of benefits of it. Through Social Media platform like Face book, Twitter, LinkedIn etc. the younger generation is getting engaged with their peer group in order to share their views towards the happenings in the Society as well as to generate, dissipate the knowledge, content to others.

Due to recent technological development, a huge amount of data generated by social networking, sensor networks, Internet, healthcare applications and many other companies, which could be structured, semi-structured or unstructured, adds more challenges when performing data storage and processing tasks. During Privacy Preserving Data Processing (PPDP), the collected data may contain sensitive information about the data owner. Directly releasing this information for further processing may violate the privacy of the data owner, hence data modification is needed in such a way that it does not disclose any personal information about the owner. On the other hand, the modified data should still be useful, not to violate the original purpose of data publishing. The privacy and utility of data are inversely related to each other. Existing privacy preserving techniques like k-anonymity, t-closeness are focusing on anonymization of data which have a fixed scheme with a small number of dimensions. There are various types of attacks on the privacy of data like linkage attack, homogeneity attack and background knowledge attack. To provide an effective technique in big data to maintain data privacy and preventing linkage attacks, this paper proposes a privacy preserving protocol - UNION, for multi-party data provider with KCL anonymization. Experiments show that this technique provides a better data utility to handle high dimensional data, and scalability with respect to the data size compared with existing anonymization techniques.

Bolted and riveted joints are important for machines and structure for the satisfactory performance. When such joints are used the plate or other member being joined will be weakened because of the holes needed to be drilled. The strength reduction depends on the diameter of drilled hole. Larger the diameter of holes drilled, greater will be the strength reduction. In the conventional design, irrespective of arrangement of bolts or rivets all bolts/rivets are considered to share same amount of load. During this work experimental investigation is carried out to estimate load shared by each rivets in different rivet arrangement. This paper presents the experimental results of loads shared by rivets in different joints. Experiments are conducted on four type of symmetric butt joint of different rivet orientation that is 0˚ 30˚ 60˚ and 90˚ from the horizontal axis. Test specimens are made of aluminium plates fastened by 6 mild steel rivets. Between each pair of rivets a pre-tensioned aluminium strip is fixed firmly and on the centre of the strip strain gauge is mounted and this specimen subjected to tensile load. By using the strain obtained from the strip load taken by each pair of rivet is determined. Results obtained for different rivet arrangements are compared. It is observed that load carried by each pair of rivets depends on rivet arrangement. Rivet closer to the central axis of plate take up more load and the rivets farther away takes up less load. This reduction in load carried depends on orientation arrangement of rivets. That is, when the rivets are arranged in 0˚ orientation (perpendicular to loading axis), all rivets share equal amount of load. Further when orientation angle are changed from 0˚ to 30˚, it observed that there is a 4-5% difference in load distribution among the rivets, also as the angle increases to 60˚ and 90˚, it observed that there is difference of 7-8% and 11- 12% of load distribution respectively.

The aim of this research is to understand the factors behind laptop purchase decisions of consumers. Nowadays companies make use of various strategies in order to attract new customers, retain existing customers and differentiate their products from those of their competitors. Perhaps, the most important and effective strategy to influence consumer behavior in the product selection is emphasizing the “brand name” of the products. Aim in this paper is to investigate how Laptop brands can influence consumer’s loyalty and Commitment. Brand equity is a set of brand assets and liabilities linked to a brand name and symbol, which add to or subtract from the value provided by a product or service. It enhances the customer’s ability to interpret and process information, improves confidence in the purchase decision and affects the quality of the user experience. Using this construct widely discussed in the literature, we use and build our hypothesis including independent variables as Perceived quality, Brand awareness, Brand association and Brand trust and Purchase intention with taking dependent variables as Customer Loyalty and Customer Commitment. In this study five laptop brand have been considered namely Apple, HP, Dell, Lenovo and Samsung and given sixth option as other brand to make a choice. The study involved a questionnaire administered to 98 respondents. Findings indicates that a majority of the Laptop buyers’ decisions are mainly influenced by Brand Association, Brand awareness and Perceived quality. Purchase intention and Brand trust do not seem to influence Customer Loyalty and Commitment for the sample of this study.

IoT (Internet of Things) is a fast growing technology, helping lots of devices to connect to the Internet. With this outbreak, attackers have been observed to take advantages of the numerous security holes in the system. This weakness can be used to exploit the core Internet infrastructure- DNS (Domain Name Service). The DNS system is choked under control of single organization and also the existing Public Key Infrastructure (PKI) needs to be overhauled. There is a need for more open distributed, decentralized model. The proposed model, utilizes the blockchain technology to implement the record storage as well as an secure open book system. Further, various cloud entities can also implement their DNS service making it distributed. An algorithm has also been devised to reduce the resolution times for the user, making it fast as well as secure. The system proposed here is an attempt to make the existing DNS infrastructure more secure, thereby reducing the risk of the Internet connected devices.

The present study is undertaken to create awareness among the methods of corrosion prevention and control the use of organic inhibitors is one of the most practiced one.

Concrete is the most widely used man-made construction material in the world. Various required performance attributes of concrete includes strength, workability and durability.To attain these characteristics, it is imperative to emphasize the mix design, which generates the above characteristics with the conservation of energy and materials. Self-Compacting Concrete (SCC) growth has become a revolutionary milestone in the history of the construction industry. SCC is a flowing concrete mixture that is able to consolidate under its own weight. The highly fluid nature of SSC makes it suitable for placing in difficult conditions and in section with congested reinforcement. Fine aggregate content is increased higher than coarse aggregates to make concrete highly flowable. It is desirable to replace river sand by M-Sand due to high fine aggregate content. In this paper, High Volume Fly ash Self-Compacting Concrete (HVFASCC) of M30 grade was designed based on Nan-Su trial and error mix design procedure. HVFASCC differs from normal SCC since the fly ash content varies from 50 to 80%. The fresh properties of SCC were characterised by EFNARC guidelines. Here Ordinary Portland Cement is replaced with 50% of fly ash. Basalt fibers were added in the mix by 0%, 0.25%, 0.5%, 0.75%, 1% of its total volume of concrete and optimum fiber content was found out. Compressive and flexural strengths were determined for all percentages of basalt fibers. The experimental test results showed marginal increase in compression and considerable increase in flexural strength. To understand basalt fiber influence on durability characteristics Rapid Chloride Permeability Test (RCPT) was carried out for 28 days cured specimens. The present work also deals with the effect of elevated temperature on Rebound Number (RN) and Ultrasonic Pulse Velocity (UPV).The exposure temperatures were 2000C and 4000C for two hours duration. The results revealed the reduction in rebound number and ultrasonic pulse velocity.

The paper design to overcome the losses of life from fire and smoke, proposed models for fire and smoke detection using image processing is provided without using additional sensors. The proposed solution is based on dynamic image processing using different mosaics pattern for both fire and smoke. The retrieve and analysis of mosaics are valuated using a statistical analysis of samples getting from different video frames and images. The proposed models can be used to detect the complete fire and smoke. It is focus to solve the issues in large areas. Past research works focused on developing the detection algorithms for processing video captured at real-times and also with sensor devices, it is required a huge amount of data storage and large scale processing therefore the complexity of algorithms is increases. The proposed method based on map-reduce function that clean and pre-process the large area video captured from the local site video devices. It basically works on frames of the video data of central cloud.

High strength self-compacting concrete (HSSCC) has gained popularity in the recent years as it can flow and fill up gaps under its own self-weight without the need of any vibration. Workability, strength and durability are the major attributes of concrete used in the construction industry. For concrete to be accepted as SCC it must satisfy certain guidelines in its fresh state which are provided by EFNARC. The flowability required for HSSCC can be achieved by increasing the powder content and thus reducing the volume of aggregates in the concrete, which means the cement content required is more and hence the heat of hydration is more which may cause shrinkage cracks. To avoid this cement is partly replaced with mineral admixtures. For the concrete to be termed as high volume fly ash self-compacting concrete the replacement of cement must be greater than 50%. In this study M60 grade self-compacting concrete was designed, where in 50% of cement replaced with fly ash. This type of concrete is termed high volume fly ash high strength self-compacting concrete (HVFAHSSCC). River sand is the most commonly used fine aggregate in concrete, in due to the boom construction activity there is a scarcity of natural sand. For strength and workability, 30% replacement of river sand by M-Sand was found to be optimum. Steel fibers were incorporated in the mix and varied in terms of volume fraction from 0.5% to 2% at an interval of 0.5%. Non-destructive tests were conducted on the specimens. Further, rapid chloride penetration test (RCPT) was also performed, and it observed that the penetration of chloride ions is reduced with increase in volume fraction of steel fibers as compared to reference mix. All specimens showed very less penetration (<1000 Coulombs) values. The concrete specimens were tested for compressive strength at various temperatures (200°C and 400°C), for a duration of 2 hours. It was observed that all specimens suffered reduction in strength at elevated temperatures.
