Abstract:

Reputation-based trust models are widely used in E-Commerce applications, and feedback ratings are aggregated to compute sellers reputation trust scores. Based on the observation that buyers often express opinions openly in free text feedback comments, it have proposed Comm Trust, a multi-dimensional trust evaluation model, for computing comprehensive trust profiles for sellers in E-Commerce applications. Different from existing multi-dimensional trust models, here compute dimension trust scores by extracting dimension ratings from feedback comments. Based on the dependency relation parsing technique, it have proposed DR-mining approaches to mine feedback comments for dimension rating profiles. Also when a new product arrives in the E-Commerce application, it doesn’t have any feedback associated with it. Hence it also introduces fuzzy logic into rule definition for preferences of venders and designs a novel agent-based decision system using fuzzy rules and reasoning mechanisms to find the right product from a trustworthy vender according to users preferences.

I. INTRODUCTION

There has been a tremendous growth in E-Commerce applications, where buyers and sellers conduct transactions on the web. Users are attracted to online-shopping not only due to the convenience in accessing the information of items on-sold, but also because of the availability of other buyers feedback on their purchasing experience, item-related and/or seller-related. All major online-shopping websites encourage buyers to provide feedback, often in the form of ratings along with some textual comments, to facilitate potential transactions..View more

Abstract:

What have we done to our environment? Everyone should ask this question to themselves. Due to increasing demand of energy, the world is leading towards the depletion of carbon fuel. Today the need of the hour is the correct transformation of energy and reuse of energy. Fossil fuel based power generating technologies have much large amount of carbon emission leading to climate change. Today the need of century is to move towards carbon free energy and find every possible way to do so. One of the possible implementation is what we have done in our research. We at Maharaja Agrasen College, University Of Delhi, have tried to use Piezoelectricity, which is a charge that accumulates in certain solid materials (such as crystals, certain ceramics, and biological matter such as bone, DNA and various proteins) in response to applied mechanical stress, pressure and vibrations. We came up with an idea to convert pressure and mechanical stress into electricity in Metro stations. The energy people apply in walking on metro station platforms is converted into electric charge which is converted into electric voltage required to charge the battery using the piezoelectric transducer generators.

I. INTRODUCTION

Daily, about 2.70 million people travel in Delhi metro. These 2.70 million riders, you see as humans, we see them as power sources and are huge power assets. We aim to quantify the mechanical energy that is generated by humans daily but gets wasted. We will install piezoelectric transducer generators on the floor of metro stations which produce electric charge whenwe apply pressure on them. This electric charge can be used to generate an electric voltage which can be used to charge batteries. Now, let’s see how piezoelectric transducer generators actually work does.

Piezoelectricity (also called the piezoelectric effect) is the appearance of an electrical potential (a voltage, in other words) across the sides of a crystal when you subject it to mechanical stress (by squeezing it). In practice, the crystal becomes a kind of tiny battery with a positive charge on one face and a negative charge on the opposite face; current flows if we Piezoelectric effect is the generation of electric charge when mechanical strain is applied on piezoelectric materials.

A. Piezoelectric Generator:

Piezoelectric effect is employed in manufacturing sensors. The piezoelectric materials are both natural and artificially made. 

Quartz is a natural piezoelectric material while Lead ZirconateTitanate (PZT) is an artificial piezoelectric material.

#ijsrd What is an electronic journal ?

What is an electronic journal?

An electronic journal is a periodical publication which is published in electronic format, usually on the Internet.
Electronic journals have several advantages over traditional printed journals:

1. You can search the contents pages and/or the full text of journals to find articles on a certain subject.
2. You can read journal articles on your desktop, you don't have to be in the Library.
3. You can e-mail articles to yourself or download them for printing.
4. The article that you want to read will always be available, even when the Library is closed.
5. Hypertext links allow you to move to different sections within individual journals or articles and can link you to related resources on the Internet.
6. Journals can include more images and audio-visual material.
7. Journals can be interactive - you can e-mail the author or editor with your comments.

Many electronic journals which are available are electronic versions of journals which exist in print. For example, if you wanted to see the journal called "Man" this journal is available physically on Level F in the Library, but is also available to SOAS users in electronic format.
Some journals are only available in electronic format and although some of these journals are of a high "academic" quality, please be aware that not all of them have gone through the same process of academic peer review as traditional print journals.

When Big Data Is Watching You

Is the answer to our feeble human minds needing to grapple with increasing quantities of big data to stand in a purpose built room immersed in complex data visualisations while wearing an array of sensors that track our physiological reactions? A group of European Commission-backed scientists believe so.
They’re attempting to quantify — and, they claim, enhance — cognition by building a sensor-based data visualisation system that dynamically changes the complexity level of the data on display in response to human triggers, such as gestures, eye movements and heart rate.
The basic concept underpinning this research, which has attracted €6.5 million in European Union funding under the Future and Emerging Technologies Scheme, is that a data display system can be more effective if it is sensitive to the human interacting with it, enabling it to modify what’s on display based on tracking and reacting to human stress signifiers.

CFD Simulation of Compact Type Mini Channel Heat Exchanger by Using of Water

Abstract—A heat exchanger is a device that is used to transfer thermal energy (enthalpy) between two or more fluids, between a solid surface and a fluid, or between solid particulates and a fluid, at different temperatures and in thermal contact. In the conventional heat exchangers, pipes are larger in size which makes heat exchanger bulky. But in some typical applications such as closed loop gas turbine heat exchangers, cryogenic applications, heat exchangers used in PWR power plants, nuclear submarines, etc., size and weight are critical design constraints on the heat exchanger. Also for high pressure applications tubes are subjected to high bending stresses. To overcome these difficulties, compact heat exchangers can be employed. Mini channels heat exchanger is a type of compact heat exchanger in which mini channels are machined on metal plates and then such plates are bonded together. Such an arrangement provides high strength so that it can be used for high pressure applications. It has been observed that in mini channels, convective heat transfer coefficient is more than the tubes used in conventional heat exchangers. Hence, the length for same heat transfer is greatly reduced which results in reduced overall size and weight of the heat exchanger. Electronic device are in heavy demand for computer processor applications and generate large amount of heat. These high power device can be cooled off very effectively by either liquid or gas coolant flowing through micro or mini channels. Continuous research work is ongoing for developing high speed processor which generate high amount of heat. Cooling of such particular systems requires high amount of mass flow rate and compactness is also required. In present work, a mini channel heat exchanger is designed with assuming inlet and outlet of hot temperature, inlet of cold water temperature and also the mass flow rates of cold and hot water. This compact heat exchanger can be used for cooling purpose of electronics device like silicon chip which would be used for microprocessor. In order to cool down silicon chip, it is kept in place of hot fluid plate. Cooling of silicon chip is required to prevent from damage and subsequently failure. The heat exchanger is designed for obtaining 10°C of hot fluid.

Optimization of Machining Parameters in CNC Turning Using Firefly Algorithm

Abstract— now a day’s machining is done through various automated machines. One of the widely used machines is CNC. Even though the automated machines are used, the quality of the work is determined by parameters used. The cutting parameters of the CNC machine determine the productivity, surface finish, machining time and other qualities of the product. This study involves the optimization of those cutting parameters. In order to get optimized CNC parameters for a specific tool-work combination, Firefly Algorithm (FA) is used to compute the best parameters based on the experiments conducted on a CNC Turning center. The three cutting parameters are cutting speed (V), feed (f), and depth of cut (d). The practical constraints have been considered during both practical and experimental approaches.  The result reveals that FA is very well suited in solving parameters selection problems.

An Automatic CAN or Plastic Bottle Crusher Machine

Abstract :

Crushers are major size reduction equipment used in mechanical and allied industries which crushes different types of soft and hard materials. The can or bottle crusher machine is widely used in beverage industries or in scrap dealers shop (Bhangarwala) to reduce the volume of the cans/bottles solely to increase the transportation volume and thus to reduce the transportation cost. Hence in this design and analysis of various parts are necessary. This paper focuses on review of a work carried out by researchers on analysis and design of various parts due to which the design quality of that parts will be improved. There are so many researchers who have done work on design and analysis, but still there are so many areas of scope regarding this design and analysis. The Electric Motor and a microcontroller make up the backbone for this project. Overall, this project involves processes like design, fabrication and assembling procedures. Even though there are many types of the can crusher machine in the market, the completion of this new model provides a more practical usage than previous one.

Performance of Multiple symbol representation with clipping scheme for PAPR reduction in OFDM systems

Abstract :

OFDM is one of the multicarrier modulation technique used in various communication systems. The major problem one faces while implementing this system is the high peak to average power .For an efficient OFDM system this PAPR should be low. In this paper a hybrid PAPR (peak to average power ratio) reduction technique for the OFDM (orthogonal frequency division multiplexing) signal which combines a multiple symbol representations method with a signal clipping method is proposed. In multiple symbol representations alternative signaling points are used to represent one symbol and PAPR is further reduced with the clipping scheme. The performance of the hybrid scheme is compared with the partial transmit sequence which is one of the other PAPR reduction scheme. In partial transmit sequence the input data is divided in to disjoint blocks transformed in to time domain sequence and rotated by phase factors. Theoretical analysis and simulation results validate that the proposed scheme has the ability to provide large PAPR reduction, low bit error rate. Performance analysis is also done with the partial transmit sequence scheme.

#IJSRD Cloud data Protection

#IJSRD E-JOunral

Protection of the privacy of the cloud Data through Multiple clouds

==============================================================

The main goal of the “Protection of the privacy of the cloud data through multiple clouds” is to identify and understand the risks associated with the cloud data and propose a distributed architecture to eliminate the risks. In particular, in current cloud architecture a client entrusts a single cloud provider with his data. It gives the provider and outside attackers having unauthorized access to cloud, an opportunity of analyzing client data over a long period to extract sensitive information that causes privacy violation of clients. Hence to overcome this we propose a distributed architecture. The distributed approach to the cloud eliminates the disadvantage of storing all data of a client to the same provider. In this approach the data sent by the client is split into different number of chunks and is distributed among multiple cloud providers. Our system consists of two major components: Cloud data distributor and Cloud providers. The Cloud Data Distributor receives the data in the form of files from many clients, splits each of the files into much number of chunks and distributes these chunks among appropriate cloud providers. Another major component which is Cloud Providers, store these chunks and responds to the chunk requests by providing the chunks.

Area-Efficient VLSI Implementation for Parallel Linear-Phase FIR Digital Filters

---------------------------------------------------------------------------------

To design an efficient integrated circuit in terms of Area, Power and speed is one of the challenging task in modern VLSI design field. In the past decade numbers of research have been carried out to optimize design based on area, speed and power utilization. In this paper performance analysis of different available adder architectures has been carried out and then we proposed a Heterogeneous architecture, which composed of four different sub adders to design an adder unit in order to demonstrate trade-offs between performance parameters i.e. Area, Power and speed. In proposed approach the symmetric coefficients of FIR filter area taken into consideration to implement parallel (L=3) FIR filter.

IJSRD Research Paper For Security Privacy in system

Research Paper On :

PRIVACY PRESERVING AGAINST NETWORK INTRUSION DETECTION IN VIRTUAL NETWORK SYSTEM

---------------------------------------------------------------------------------

Authors :

SHRUTHI S , RNS INSTITUTE OF TECHNOLOGY

Description :

Cloud security is one of most important issues that has attracted a lot of research and development effort in past few years. Particularly, attackers can explore vulnerabilities of a cloud system and compromise virtual machines to deploy further large-scale Distributed Denial-of-Service(DDoS). DDoS attacks usually involve early stage actions such as multi-step exploitation, low frequency vulnerability scanning, and compromising identified vulnerable virtual machines as zombies, and finally DDoS attacks through the compromised zombies. Within the cloud system, especially the Infrastructure-as-a-Service (IaaS) clouds, the detection of zombie exploration attacks is extremely difficult. This is because cloud users may install vulnerable applications on their virtual machines. To prevent vulnerable virtual machines from being compromised in the cloud, we propose a multi-phase distributed vulnerability detection, measurement, and countermeasure selection mechanism called NICE, which is built on attack graph based analytical models and reconfigurable virtual network-based countermeasures.
