Adaptive Neural Network Based Energy Management System for Grid Integrated Hybrid System
No full textRenewable energy sources play an important role in electrical energy generation. The drawbacks of Renewable energy sources have been overcome by the use of hybrid power generating unit. A typical hybrid renewable energy system (HRES) combines several renewable energy sources such as wind turbine (WT) and photovoltaic (PV) panels as primary energy sources and an energy storage system (ESS) based on fuel cell and battery. All of the energy sources are connected together to a central dc bus by means of power converters. This paper includes a supervisory control called adaptive neural network which determines the power that must be generated by/stored in the fuel cell and battery, taking into account the control demand by the grid, the offered power, the hydrogen reservoir point and the state-of-charge (SOC) of the battery. The proposed EMS is compared with classical EMS composed of state based supervisory control system based on states and inverter control system based on PI controller. Dynamic simulation results of the proposed EMS demonstrate the better performance than the classical EM
Secure & Optimal Resource Allocation in Cloud for Media Streaming Applications
No full textCloud computing is latest high-end technology that has enormous popular demand in cooperative and trade advertising operations. Cloud provider provides resources to organization to store their data and perform computational operations in order to minimize infrastructure cost and increases resources utilization. So that reduces the organization infrastructure investment by reusing existing resource instead of purchase individual license for product and maintenance. Pay as-you-go model is beneficial for organization for use of applications widely. The major region to improve cloud environment is security and Quality of service where delay should minimize by allocate resources for media streaming application in cloud efficiently. Demand of end users increases when trusted, reliable cloud is available. Paper studies on how to provide security and how to allocate resource with minimal cost and delay with optimal window size and reservation time. Security issues are solved by using Ping-Pong based algorithm where it is light weight algorithm. Moreover in our methodology use Ping-Pong by adding further user credentials for keeping user details secure in cloud. Media content provider load is reduce by adding demand forecast and predictive based resource allocation algorithm. Implementation of paper use Netbeans, myjelastic cloud plugin and performance graph represent analysis on cost with nonlinear time discount tariffs of resource allocation
An Enhancement for finding User Behavior on Progressive Data Using Weight Constraint
No full textEvery Organizations need to understand their customer’s behavior, preferences and future needs every time depend on past behavior. Web Usage Mining is an active research topic in which user session clustering is done to understand user’s activities. I am proposing an enhancement to the web log mining process based on online navigational pattern prediction. In this paper, I use Neural based approach Self Organizing Mapping for clustering of session as a trend analysis with some parameters. It depends on the performance of the clustering of the number of requests. Here I am using SOM algorithm in Frequent Sequential Traversal Pattern Mining called STPMW. By proceeding this way, first I use SOM algorithm and getting some cluster of web-logs. Here we load that web-log cluster which is nearly related to frequent pattern. After that I am applying Min-Max Weight of Page in Sequential Traversal Pattern. If given support comes between min and max of weight range so item is frequent else I check average weight. Finally I am establish good prediction with quantity of data and the quality of the results
Digital image watermarking based on canny edge detection and texture block in DWT
No full textA new digital image watermarking algorithmbased on texture block and canny edge detection in thediscrete wavelet domain is proposed in order to balancebetween the invisibility and robustness and improve theability of resisting to geometric attacks of the digital imagewatermark. In the algorithm, the texture blocks are extractedafter the edge detection for the original image with thecanny operator by using the masking property of humanvisual system, in which the watermark is embeddedadaptively both in the low-frequency sub-band and the highfrequencysub-band in the discrete wavelet domain. Theexperiment result shows the watermark has good invisibilityand robustness as well as the ability of resisting to geometricattacks by using the algorithm proposed in this paper. At thesame time three keys generated in the embedding processthat can raise the security of the watermark.Rapid evolution of digital technology has improved the easeof access to digital information enabling reliable, faster andefficient storage, transfer and processing of digital data. Italso leads to the consequence of making the illegalproduction and redistribution of digital media easy andundetectable. Hence, the risk of copyright violation ofmultimedia data has increased due to the enormous growthof computer networks that provides fast and error freetransmission of any unauthorized duplicate and possiblymanipulated copy of multimedia information. Apreprocessing step before the watermark extraction has beenproposed which makes the algorithm resilient to geometricattack i.e. RST attack. Performance of this watermarkingscheme has been analyzed by evaluating the robustness ofthe algorithm against geometric attack including rotation,scaling, translation (RST) and some other attacks.Experimental results have been compared with existingalgorithm which seems to be promisin
Light Fidelity At Some Inclined Angle
No full textNowadays people prefer wireless network to wired network, though the network speed is not constant they use wireless network because they provides us many benefits like portability and flexibility. We have Wi-Fi hotspots at home, coffee shops, airports, hotels and even cities. Due to this, Radio spectrum is getting clogged day by day and demand for wireless network is increasing drastically every year. An emerging technology using Visible Light Communications (VLC) for high speed wireless communications is Light Fidelity commonly known as Li-Fi. Li-Fi uses light as a carrier signal instead of radio frequency as in Wi-Fi. Li-Fi is a technology that uses LED's to transmit data without wire. LED is the key component in this data transmission as LED has the capacity of fast switching ON and OFF. The major problem faced in Li-Fi technology is, if the receiver or the photo detector is inclined at some angle then it doesn‟t have the capacity to receive the particular light signal that consist of the data that is being transmitted by the Li-Fi LED bulbs. The main objective of this paper is to implement the absorption concept i.e. using high sensitive photo detector when it is inclined to some angle it must start absorbing the light that is being transmitted by the LED bulb
Study on the anti histaminic activity of Achyranthes aspera L. and Tephrosia L. on experimental rats
No full textThis presence of histamine which causes burning, sensation, redness and inflammation of tissue during allergic response. However when histamine is released, it triggers a series of dramatic actions. The blood vessels become larger and the speed of the blood flowing through them slow. These changes in size, volume of cells and blood vessels allow fluid to leak through cell walls. This fluid causes swelling of the surroundings tissues. The inflamed tissue become irritated and swollen. Histamine also cause smooth muscles to contract. Asthma is covered by over secretion of histamine from the mast cells. There are number of histamine blockers which may inhibit the release of histamine. The plant products in the form of secondary metabolites particularly 'saponins' when given to the experimental animals inhibit histamine by suppressing the H1 and H2 receptors. Therefore the problem will provide in-vivo mechanism of histamine blockers and will help us to understand the histological details of the mechanism
IMPACT OF GLOBLIZATION ON RETAIL MARKETING IN INDIA” [WITH SPECIAL REFRENCE OF INDORE]
No full textThe Indian retail industry is only now beginning to evolve in line with the transformation that has swept other large economies. Fifty years of restricting the consumer goods industry, a national mindset which favored denial over indulgence, and a fractured supply chain for agricultural products have all contributed to prevent the development of modem tenants based on scale advancements and consumer preferences
Incorporating Logical Computation on Stochastic bit streams
No full textMost advanced frameworks work on a positional representation of information, for example, double radix. A positional representation is a smaller approach to encode sign qualities: in parallel radix, 2n unique qualities can be spoken to with n bits. Notwithstanding, working on it requires complex rationale: in every operation, for example, expansion or duplication, the sign must be "decoded," with the higher request bits weighted more than the lower request bits. We advocate an option representation: irregular bit streams where the sign quality is encoded by the likelihood of acquiring an one Vs a zero. That shows is a great deal less minimal than paired radix. Notwithstanding, complex operations can be performed with extremely straightforward rationale. For example, duplication can be performed with a solitary AND door. Furthermore, in light of the way that the representation is uniform, with all bits weighted compared and it is very tolerant of delicate blunders (i.e., bit flips). In this paper, we introduce a general strategy for combining advanced hardware that registers on such stochastic bit streams. Our strategy can be utilized to combine discretionary polynomial capacities. Through polynomial estimates Investigates it can likewise be utilized to combine non-polynomial capacities capacities utilized as a part of picture handling demonstrate that our system produces circuits that are exceedingly tolerant of data mistakes. The precision corrupts nimbly with the mistake rate. For applications that command basic equipment, creating generally low exactness calculation dependably, our technique is a winning suggestion
Design and Verification of AXI OCP Bridge Supporting Out-of-Order Transactions for achieving Dead Lock Free Communication
No full textModern on-chip communication protocols such as advanced eXtensible interface and open core protocol support advanced transactions to improve communication efficiency. Out-of- order transactions that allow responses to be returned in an order different from their request order play an important role in this improvement. However, a deadlock situation may occur if these transactions are not properly manipulated. In this paper, we address the deadlock problem in an onchip bus system supporting out-of-order transactions. We present a graphic model that can well represent the status of a bus system and show that a cycle exists in the graph if and only if the bus system is in an unsafe state that may lead to a bus deadlock. Based on this model, we propose a novel bus design technique that can efficiently resolve the bus deadlock problem. Experimental result show that buses with the proposed technique can be up to 3.3 times faster than those with the currently available techniques
