Open Loop Control of a Novel Power Converter for FuelCell assisted Photovoltaic Power Systems[ ]


A novel DC-DC converter is proposed in the work carried out powered from multiple sources such as PV and Fuel Cell while the Battery is used as the Back-Up source.The power conversion circuit consists of less number of active power switches with associated passive components. By adjusting the duty-ratio of the active power switch, the power sharing between sources as well as the output voltage regulation can be made.According to various situations, the operational states of the proposed converter can be divided into three states based on battery utilization .In order to ensure that the system operates with high efficiency, this paper proposes a power management control scheme, which controls the bidirectional converter operating under boost mode according to the operation condition of the PV/Fuel Cell, so that the battery can be charged or discharged. The system performance under different solar Irradiance has been verified by carrying out simulation studies using a load demand of 2.5 KW.The integration of the hybrid renewable power system is implemented and simulated using MATLAB/SIMULINK.

Effect of Salt-Contaminated Mixing Water and Aggregates on Time-to-Initiate Rebar Corrosion in Concrete[ ]


Durability problems occurring in reinforced concrete structures have become a major concern to end-users. Particularly, structures that are built near shoreline normally suffer premature deterioration due to corrosion of their reinforcing steel bars which is caused by continuous ingress of chlorides from seawater into the concrete cover. Making this problem more serious is the use of salt-contaminated mixing water and sea-based aggregates in making concrete - a very common practice in coastal rural areas where concrete ingredients are taken from near-shoreline sources. This study was conducted in order to quantify the effect of salt-contaminated aggregates and water on the time-to-initiate corrosion of steel bars in concrete. Six types of concretes was used: a control sample, concrete containing salty aggregates, concrete mixed on seawater, and concretes mixed with 10%, 20% and 30% salt solution, respectively. Corrosion monitoring was done via impressed current where the corrosion activity on steel bars was monitored by a Silver-Silver Chloride Electrode (SCE) under laboratory controlled conditions. Results have showed that concrete mixed with salt-contaminated aggregates and mixing water, produced a faster corrosion of steel bars than the normal concrete.

The Effect of the Right-Wing Media on Public Knowledge of the Affordable Care Act (ACA)[ ]


Bill Hicks, a famous comedian known for his abrasive, acerbic style of humor, argued in the 1990s that the Media was working against the public's interest by spinning and misrepresenting data. This is evident in the modern day as public knowledge of the Affordable Care Act (ACA) is distorted and misrepresented by the misinformation presented by the right-wing media through psychological framing. The conclusion is not only corroborated by specific cases of conservative vitriol but also by the statistics showing the knowledge base of each news network's audience demographic. The "information process" as outlined by Hicks can be delineated into three separate parts, and it is through this course that we find Hicks' argument truly manifest in the modern day. Because of the misinformation phenomenon found in the ACA, it is possible that the very purpose of democracy is being countered as voter bases are acting against their own best interests.

JANUS: The Protector of Virtual Machine Networks[ ]


Developing a virtual machine security tool manually is generally believed to be a tedious, time consuming, and error-prone process because of the large semantic gap. Recent advances in the field of virtualization show that we can largely narrow this semantic gap. But still there is no completely automated tool for VM security. In this paper, we present JANUS, an entirely new technique for VM security that can automatically bridge the semantic gap. The key idea is that, through oursystem, we will automatically redirect all the requests coming into the virtual machine network to our monitoring machine which will identify the valid or authentic requests and redirect them to the respective machines after they have been logged in the database. This system acts as a gateway for the VM network and offers a number of new features and capabilities. Particularly, it automatically enables inspection of every single request coming into the network and hence ensures high security. We have tested our system on several commonly used utilities on top of different kernels. The experimental results show that our technique is general (largely OS-agnostic), and it introduces 9.3X overhead on average for the redirected requests as compared to the native non-redirected ones.

Comparative Analysis and Evaluation of Critical Success Factors and Barriers of Power Quality Programme Implementation Failure in Developing Countries[ ]


The aim of this paper is to study the implementation of a Power Quality Programme (PQP) framework, and the obstacles and barriers faced by Libyan Distribution Networks (LDNs) in implementing a PQP. Firstly, to identify the most critical success factors that would have a major impact on PQP implementation in LDNs. Five Critical Success Factors (CSFs) for PQP were identified to examine the level of power quality in LDNs. They are PQ awareness, PQ disturbances, PQ management commitment, PQ employee's participation and training and PQ customers' satisfaction. It revealed that all five CSFs were significantly affected by the level of PQ awareness, and the suspension of PQP implementation. An appropriate PQP framework was developed for the purpose of this study to guide LDNs as a case study on developing countries. The proposed PQP framework model was validated based on the identified CSFs, and the barriers and benefits of PQP, which were analysed using different techniques based on both SPSS and NVivo software. The PQP framework was developed from the findings based on the responses of 397 PQ survey participants, and supported by 44 face-to-face semi-structured interviews conducted with professionals and expert LDNs staff. Out of 16 PQP barriers, 13 were statistically significant, which indicated that Libya distribution systems have already surmounted various barriers to implementing a PQP effectively. This framework encourages and guides the implementation teams to have an obvious and clear awareness and vision of how to prevent existing obstacles from reappearing in different forms, leading to long-term PQP improvements. There were 11 overall benefits of PQP implementation, which would have a positive impact on LDNs.

Awareness on Confidentiality in Social Networking Sites[ ]


Privacy concerns with social networking sites have become a controversial topic since the evolution of Bebo, Friendster, My Space, Orkut and Facebook. With the increasing popularity certain issues related to stalking, identity theft, sexual predators, phishing and employment are consistently on the higher side. Also in social networking sites the ethics regarding data storage, management and sharing of data is still a big concern. A security issue occurs when a hacker gains unauthorized access to a site's protected coding. The potential harm to an individual depends on how much a user engages in social networking site and the amount of private information he shares. It is possible to identify the risks and design preventive measures to protect our confidential data in social networking sites. We therefore need to improve the safety measures regularly in line with the latest technological development like maintaining physical, electronic and procedural safeguards or computer safeguards such as firewall and data encryption.

Parallelizing Digital Library Search[ ]


Digital libraries today are expected to store millions of articles or items of interest. Inexpensive and efficient access to this information becomes critical for success of digital libraries. In order to keep the costs of maintaining digital libraries low, computer programs are taking on the tasks that were traditionally carried out by skilled professional such as librarians. Such tasks often include selection, cataloging and indexing of items in the digital library. Once articles in a digital library are indexed with a set of keywords, computer programs are efficient at retrieving articles that are of interest to a digital library user by resorting to keyword searches of the index database based on user specified keywords. Our research work is investigating ways to speed up implementation and improve experience of using digital libraries. As part of this effort we are investigating ways to use new language extensions such as the Intel Cilk Plus extensions to C and C++ from Intel Corporation that offer a quick, easy and reliable way to improve the performance of programs on multi core processors. Multi core systems are now becoming prevalent on desktops, servers and even laptops. In this paper, we present the results from our work using the Cilk Plus extensions to parallelize digital library searches for articles of interest.

Hierarchical Privacy Preserving Distributed Frequent Itemset Mining Over Verically Distributed Dataset[ ]


The process of defining association rules is dependent of frequent itemsets. Distributed data mining is a significant scenario due to the fact of large quantity of data and adaptive resource sharing between networks that provides computational strength. In this context data that is high in volume need to be distributed to various computational clients to perform data mining in distributed manner, which is scalable in regard to computation and process time. Henceforth it become a serious issue to protect the privacy of the data that distributed for mining. Here in this paper we explored a novel perturbation technique called connected guassian approach (CGA) to protect the data privacy that distributed and a distributed frequent itemset mining modal. The model here we proposed is referred as hierarchical privacy preserving distributed frequent itemset mining (HPPDFIM) that applied on vertically partitioned data tuples. The other underlying goal of the proposed model is that achieving privacy by using one way digestive standard during communication between distributed computational resources involved in DDM. The experiments revealed that the model is scalable and accurate unlike other perturbation standards. In a glance the goals of the proposed HPPDFIM is (i) protecting privacy during the distribution of the vertically partitioned data tuples even distributed computational resources compromised, (ii) achieving privacy during the conversations between participant distributed computational resources, (iii) and the frequent itemset mining should be done such that each node of the network that participating in mining process should not aware of the transaction elements of the other nodes that are involving in data mining process.

Enhancement of dc ionic conductivity with particle size of dispersoid in XKNO3 - 1-X Ba(NO3)2 [ ]


The ionic conductivity of XKNO3 -1-XBa(NO3)2 mixed crystals, sx, has been measured from nearly 360K to close to their melting points. The conductivity in the extrinsic region of Ba(NO3)2 increased as the m/o of KNO3 is increased up to 91m/o and then for 95 m/o the conductivity falls. The further enhancement in conductivity of about three orders is found with the dispersion of Al2O3 to the 91 m/o of KNO3 in Ba(NO3)2. DSC and XRD studies reveal that no new phase is formed. The enhanced conductivity is attributed to the excess cation vacancies generated in the space charge region of the matrix phase surrounding the alumina particles as a consequence of stabilization of cations at the dispersoid surface due to internal absorption.
