The primary goal of data visualization is to communicate information clearly and efficiently via statistical graphics, plots and information graphics.Data visualization helps us to communicate our insights quickly and effectively. Any type of data, which is represented by a visualization allows users to compare the data, generate analytic reports, understand patterns and thus helps them to take the decision. Data visualizations can be interactive, so that users analyze specific data in the chart. Well, Data visualizations can be developed and integrated in regular websites and even mobile applications using different JavaScript frameworks.What is D3.js?D3.js is a JavaScript library used to create interactive visualizations in the browser. The D3.js library allows us to manipulate elements of a webpage in the context of a data set. These elements can be HTML , SVG , or Canvas elements and can be introduced, removed, or edited according to the contents of the data set. It is a library for manipulating the DOM objects. D3.js can be a valuable aid in data exploration, it gives you control over your data's representation and lets you add interactivity.Why Do We Need D3.js?D3.js is one of the premier framework when compare to other libraries. This is because it works on the web and its data visualizations are par excellence. Another reason it has worked so well is owing to its flexibility. Since it works seamlessly with the existing web technologies and can manipulate any part of the document object model, it is as flexible as the Client Side Web Technology Stack (HTML, CSS, and SVG). It has a great community support and is easier to learn.D3.js FeaturesD3.js is one of the best data visualization framework and it can be used to generate simple as well as complex visualizations along with user interaction and transition effects. Some of its salient features are listed below:∙Extremely flexible. ∙Easy to use and fast. ∙ Supports large datasets.1.D3.js∙Declarative programming.∙Code reusability.∙Has wide variety of curve generating functions.∙Associates data to an element or group of elements in the html page.D3.js BenefitsD3.js is an open source project and works without any plugin. It requires very less code and comes up with the following benefits:∙Great data visualization.∙It is modular. You can download a small piece of D3.js, which you want to use. No need to load the whole library every time.∙Easy to build a charting component.∙DOM manipulation.In the next chapter, we will understand how to install D3.js on our system.6D3.js 7In this chapter, we will learn how to set up the D3.js development environment. Before we start, we need the following components:∙D3.js library ∙Editor ∙Web browser ∙ Web serverLet us go through the steps one by one in detail.D3.js LibraryWe need to include the D3.js library into your HTML webpage in order to use D3.js to create data visualization. We can do it in the following two ways:∙Include the D3.js library from your project's folder. ∙ Include D3.js library from CDN (Content Delivery Network).Download D3.js LibraryD3.js is an open-source library and the source code of the library is freely available on the web at https:/// website. Visit the D3.js website and download the latest version of D3.js (d3.zip). As of now, the latest version is 4.6.0.After the download is complete, unzip the file and look for d3.min.js . This is the minified version of the D3.js source code. Copy the d3.min.js file and paste it into your project's root folder or any other folder, where you want to keep all the library files. Include the d3.min.js file in your HTML page as shown below.Example: Let us consider the following example.2.D3.js is a JavaScript code, so we should write all our D3 code within “script” tag. We may need to manipulate the existing DOM elements, so it is advisable to write the D3 code just before the end of the “body” tag.Include D3 Library from CDNWe can use the D3.js library by linking it directly into our HTML page from the Content Delivery Network (CDN). CDN is a network of servers where files are hosted and are delivered to a user based on their geographic location. If we use the CDN, we do not need to download the source code.Include the D3.js library using the CDN URL https:///d3.v4.min.js into our page as shown below.Example: Let us consider the following example.8D3.js EditorWe will need an editor to start writing your code. There are some great IDEs (Integrated Development Environment) with support for JavaScript like –∙Visual Studio Code∙WebStorm∙Eclipse∙Sublime TextThese IDEs provide intelligent code completion as well as support some of the modern JavaScript frameworks. If you do not have fancy IDE, you can always use a basic editor like Notepad, VI, etc.Web BrowserD3.js works on all the browsers except IE8 and lower.Web ServerMost browsers serve local HTML files directly from the local file system. However, there are certain restrictions when it comes to loading external data files. In the latter chapters of this tutorial, we will be loading data from external files like CSV and JSON. Therefore, it will be easier for us, if we set up the web server right from the beginning.You can use any web server, which you are comfortable with – e.g. IIS, Apache, etc.Viewing Your PageIn most cases, we can just open your HTML file in a web browser to view it. However, when loading external data sources, it is more reliable to run a local web server and view your page from the server (http://localhost:8080).93.D3.jsD3.js is an open source JavaScript library for –∙Data-driven manipulation of the Document Object Model (DOM).∙Working with data and shapes.∙Laying out visual elements for linear, hierarchical, network and geographic data.∙Enabling smooth transitions between user interface (UI) states.∙Enabling effective user interaction.Web StandardsBefore we can start using D3.js to create visualizations, we need to get familiar with web standards. The following web standards are heavily used in D3.js.∙HyperText Markup Language (HTML)∙Document Object Model (DOM)∙Cascading Style Sheets (CSS)∙Scalable Vector Graphics (SVG)∙JavaScriptLet us go through each of these web standards one by one in detail.HyperText Markup Language (HTML)As we know, HTML is used to structure the content of the webpage. It is stored in a text file with the extension “.html”.Example: A typical bare-bones HTML example looks like thisDocument Object Model (DOM)When a HTML page is loaded by a browser, it is converted to a hierarchical structure. Every tag in HTML is converted to an element / object in the DOM with a parent-child hierarchy. It makes our HTML more logically structured. Once the DOM is formed, it becomes easier to manipulate (add/modify/remove) the elements on the page.Let us understand the DOM using the following HTML document:The document object model of the above HTML document is as follows,11Cascading Style Sheets (CSS)While HTML gives a structure to the webpage, CSS styles makes the webpage more pleasant to look at. CSS is a Style Sheet Language used to describe the presentation of a document written in HTML or XML (including XML dialects like SVG or XHTML). CSS describes how elements should be rendered on a webpage.Scalable Vector Graphics (SVG)SVG is a way to render images on the webpage. SVG is not a direct image, but is just a way to create images using text. As its name suggests, it is a Scalable Vector. It scales itself according to the size of the browser, so resizing your browser will not distort the image. All browsers support SVG except IE 8 and below. Data visualizations are visual representations and it is convenient to use SVG to render visualizations using the D3.js.Think of SVG as a canvas on which we can paint different shapes. So to start with, let us create an SVG tag:The default measurement for SVG is pixels, so we do not need to specify if our unit is pixel. Now, if we want to draw a rectangle, we can draw it using the code below:13We can draw other shapes in SVG such as – Line, Circle, Ellipse, Text and Path.Just like styling HTML elements, styling SVG elements is simple. Let us set the background color of the rectangle to yellow. For that, we need to add an attribute “fill” and specify the value as yellow as shown below:JavaScriptJavaScript is a loosely typed client side scripting language that executes in the user's browser. JavaScript interacts with HTML elements (DOM elements) inorder to make the web user interface interactive. JavaScript implements the ECMAScript Standards , which includes core features based on ECMA-262 specifications as well as other features, which are not based on the ECMAScript standards. JavaScript knowledge is a prerequisite for D3.js.D3.jsSelections is one of the core concepts in D3.js. It is based on CSS selectors. It allows us toselect one or more elements in a webpage. In addition, it allows us to modify, append, or remove elements in a relation to the pre-defined dataset. In this chapter, we will see how to use selections to create data visualizations.D3.js helps to select elements from the HTML page using the following two methods:∙select() – Selects only one DOM element by matching the given CSS selector. If there are more than one elements for the given CSS selector, it selects the first one only. ∙selectAll() – Selects all DOM elements by matching the given CSS selector. If you are familiar with selecting elements with jQuery, D3.js selectors are almost the same.Let us go through each of the methods in detail.The select() methodThe select() method selects the HTML element based on CSS Selectors. In CSS Selectors, you can define and access HTML-elements in the following three ways:∙ Tag of a HTML element (e.g. div, h1, p, span, etc.,) ∙ Class name of a HTML element ∙ID of a HTML elementLet us see it in action with examples.Selection by TagYou can select HTML elements using its TAG. The following syntax is used to select the “div” tag elements, Example: Create a page “select_by_tag.html” and add the following changes, 4.By requesting the webpage through the browser, you will see the following output on the screen:Selection by Class nameHTML elements styled using CSS classes can be selected by using the following syntax.Create a webpage “select_by_class.html” and add the following changes:By requesting the webpage through the browser, you will see the following output on the screen.Selection by IDEvery element in a HTML page should have a unique ID. We can use this unique ID of an element to access it using the select() method as specified below.Create a webpage “select_by_id.html” and add the following changes.By requesting the webpage through the browser, you will see the following output on the screen.Adding DOM ElementsThe D3.js selection provides the append() and the text() methods to append new elements into the existing HTML documents. This section explains about adding DOM elements in detail. The append() MethodThe append() method appends a new element as the last child of the element in the current selection. This method can also modify the style of the elements, their attributes, properties, HTML and text content.Create a webpage “select_and_append.html” and add the following changes:17Requesting the webpage through browser, you could see the following output on the screen,Here, the append() method adds a new tag span inside the div tag as shown below:The text() MethodThe text() method is used to set the content of the selected / appended elements. Let us change the above example and add the text() method as shown below.1819Now refresh the webpage and you will see the following response.Here,the above script performs a chaining operation. D3.js smartly employs a technique called the chain syntax , which you may recognize from jQuery . By chaining methods together with periods, you can perform several actions in a single line of code. It is fast and easy. The same script can also access without chain syntax as shown below.Modifying ElementsD3.js provides various methods, html(), attr() and style() to modify the content and style of the selected elements. Let us see how to use modify methods in this chapter.The html() MethodThe html() method is used to set the html content of the selected / appended elements. Create a webpage “select_and_add_html.html” and add the following code.20By requesting the webpage through the browser, you will see the following output on the screen.The attr() MethodThe attr() method is used to add or update the attribute of the selected elements. Create a webpage “select_and_modify.html” and add the following code.21End of ebook previewIf you liked what you saw…Buy it from our store @ https://22。

At just 14 years old, Heman Bekele emerged as the victor of the 2023 Young Scientist Challenge, standing out among the ten finalists with his innovative creation known as the Skin Cancer Treating Soap (SCTS).Bekele’s brilliant concept centers on the development of a soap that is not only affordable, but also has the potential to reactivate the body’s natural defenders of the skin to stop skin cancer. In Bekele’s own words, “Curing cancer, one bar of soap at a time. ”He always has endless passion for biology and technology, and the Young Scientist Challenge just provided him with the perfect platform to display his ideas. Reflecting on his inspiration, Bekele shared that his childhood played a significant role in shaping his innovative thinking. Having witnessed people work tirelessly under the sun, he couldn’t help but wonder how many were aware of the risks associated with constant sun exposure.“I wanted to make my idea not only scientifically exceptional but also accessible to a broad audience,” Bekeleexpressed during an interview with the media. He received invaluable guidance from Deborah Isabelle, a product engineering specialist, who connected him with other scientists to aid him in reaching his ambitious plans.During his presentation, Bekele passionately expressed his vision of turning the soap into “a symbol of hope, accessibility, and a world where skin cancer treatment is within reach for all.”Over the coming five years, Bekele longs to perfect his invention and establish a nonprofit organization devoted to distributing his innovative creation to more places including undeveloped communities, offering hope and a practical solution in the fight against skin cancer.4. What made Bekele an instant hit?A. Starting a soap fashion.B. Overcoming skin cancer.C. Being the youngest scientist.D. Creating a soap against skin cancer.5. What inspired Bekele to invent SCTS?A. His concern for others.B. His adventure in childhood.C. His enthusiasm for technology.D. His interest in medical knowledge.6. What will Bekele do in the near future?A. Obtain official approval.B. Visit undeveloped areas.C. Increase the availability of the soap.D. Update the facilities of production.7. Which of the following can best describe Bekele?A. Inspiring and modest.B. Humorous and positive.C Creative and considerate. D. Curious and independent..CIn the animal world, speed is king. Fast animals have a leg up in outrunning other animals, which puts them high on the food chain. It would seem that all animals would go for speed, but then there’s the sloth (树懒). While a lion can go from 0 to 60 miles an hour in only five seconds, it takes a sloth all day to cover no more than 50 meters.Sloths live entirely in trees on a diet of leaves. And for this, they are extremely rare. While most of the land world is covered in trees, there are very few vertebrates (脊椎动物) that call the tree home. The aim of a 2016 study, says Jonathan Pauli, a University of Alabama professor of forest and wildlife ecology, was to help uncover why sloths are indeed so unique. “Among vertebrates, this is the rarest of lifestyles”, says Pauli. “When you picture animals that live off plant leaves, they are almost all big-things like deer. What’s super interesting about sloths is that they can’t be big.”For their research, Pauli and his Wisconsin team studied wild sloths at a field site. When the researchersmeasured the energy use of sloths, they found a wildly low burning of as little as 110 calories of energy a day. And for this, they take the cake: it is the lowest measured energetic output for any mammal (哺乳动物).“The measurement was intended to find out what it cost sloths to live over a day,”says Pauli, who adds that a diet of little but leaves lacks nutritional value and the animal’s small size doesn’t allow for overeating-so sloths need to find ways to make the most of their diets, which means using tiny amounts of energy, dramatic control of body temperature and living at an extremely slow pace.Their reward? A wonderfully widespread ecological system to call their own, one slow inch at a time.8. Why is a lion mentioned in Paragraph 1?A. To admire lions’ speed.B. To state sloths’ weakness.C. To confirm lions’ lead position.D. To highlight sloths’ uniqueness.9. What is the 2016 study mainly about?A. The lifestyle of sloths.B. The diet of vertebrates.C. The species of rare animals.D. The energy use of creatures.10. What does the underlined part “take the cake” in Paragraph 3 probably mean?A. Break down.B. Keep on.C. Stand out.D. Grow up.11. What can be inferred about sloths from Pauli’s words?A. Their slow pace is a balanced choice.B. They are in face of possible extinction.C. Their slow pace decides a tiny appetite.D. They suffer a lot against natural enemies.DFrom the day we’re born, curiosity becomes a primary driving force that motivates us to explore unknown ideas and territories in search of answers and stimulations. Human beings have an inborn desire to close the “curiosity gap” every day.A recent study found that curiosity can be a highly effective way to lead people to make smarter and healthier lifestyle choices. Evan Polman, assistant professor of marketing at the University of Wisconsin-Madison, said, “Our research shows that fueling people’s curiosity can influence their choices by turning them away from inviting desires, like unhealthy foods or taking the elevator, and toward less inviting but healthier options, such as buying more fresh produce or taking the stairs.”To prove the positive potential of the curiosity gap, Polman and his team conducted a series of experiments designed to test how curiosity affected the choices people made positively. In each study, arousing curiosityresulted in noticeable behavior change. For example, in one of the experiments, Polman increased the number of participants who chose to watch a video of academic nature by promising that they would reveal the secret behind a magic trick at the end of the video.The results of the field studies on curiosity were particularly convincing to Polman. In one field study, the researchers created a 10 percent increase in the use of stairs in a university building by posting trivial (琐事) questions near the elevators and posting the answers in the stairwell. In another, they increased the purchase of fresh produce by placing a joke on the posters describing the fruit or vegetable.Polman was surprised by the degree that taking advantage of the curiosity gap could motivate people to automatically make healthier lifestyle choices. He concluded, “Our results suggest that using interventions based on curiosity gaps has the potential to increase participation in desired behaviors for which people often lack motivation.

Facebook then attempts to make money by selling their data to advertisers that want to send targeted messages.Most Facebook users don't realize this is happening. Even if they know what the company is up to，they still have no idea what they're paying for Facebook，because people don't really know what their personal data is worth.The biggest problem，however，is that the company keeps changing the rules. Early on，you could keep everything private. That was the great thing about Facebook⼀-you could create your own little private network. Last year，the company changed its privacy rules so that many things-your city，your photo，your friends' names-were set，by default(默认)，to be shared with everyone on the Internet.According to Facebook's vice-president Elliot Schrage，the company is simply making changes to Im proveIts servIce，and if people don't share information，they have a "less satisfying expenence."Some critics think this is more about Facebook looking to make more money. Its original business model，which involved selling ads and putting them at the side of the page，totally failed. Who wants to look at ads when they're online connecting with their friends?The privacy issue has already landed Facebook in hot water in Washington. In April，Senator Charles Schumer called on Facebook to change its privacy policy. He also urged the Federal Trade Commission to set guidelines for social-networking sites. "I think the senator rightly communicated that we had not been clear about what the new products were and how people could choose to use them or not to use them，" Schrage admits.I suspect that whatever Facebook has done so far to invade our privacy，it's only the beginning.Which is whyI'm considering deactivating(撤销) my account. Facebook is a handy site，but I'm upset by the idea that my information is in the hands of people I don't trust. That's too high a price to pay.11. What do we learn about Facebook from the first paragraph?A. It is a website that sends messages to targeted users.B. It makes money by putting on advertisements.C. It pro v ide s load s of information t o it s u se r s.D. It profits by selling its users' personal data.12.What does the author say about most facebook users ?A. They care very little about ttheir personal information.B. They are reluctant to give up their personal information.C. They don't know their personal data enriches Facebook.D. They don't identify themselves when using the website.13. Why does Facebook make changes to its rules according to Elliot Schrage?A. To conform to the Federal guidelines.B. To improve its users' connectivity.C. To render better service to its users.D. To expand its scope of business.14. What does Senator Charles Schumer advocate?A. Setting guidelines for advertising on websites.B. Formulating regulations for social-networking sites.C. Banning the sharing of users' personal information.D. Removing ads from all social-networking sites.15. Why does the author plan to cancel his Facebook account?A. He finds many of its users untmstworthy.B. He is upset by its frequent rule changes.C. He doesn't want his personal data abused.D. He is dissatisfied with its current service.第三部分:概括段落⼤意和补全句⼦。

huge amount of data in a centralized way is ineffective due to extensive access latency and load on the central server.Data Grids aggregate a collection of distributed resources placed in different parts of the world to enable users to share data and resources.Data replication is an important technique to manage large data in a distributed manner.There are three key issues in all the data replication algorithms which are replica placement, replica management and replica selection.Meanwhile, even though the memory and storage size of new computers are ever increasing, they are still not

from replication as well as reducing storage cost and mean job execution time.Data replication is a key optimization technique for reducing access latency and managing large data by storing data in a wise manner.Effective scheduling in the Grid can reduce the amount of data transferred among nodes by submitting a job to a node where most of the requested data files are available.Effective scheduling of jobs is necessary in such a system to use available resources such as computational, storage and network efficiently.Storing replicas close to the users or grid computation nodes improves response time, fault tolerance and decreases bandwidth consumption.The files of Grid environments that can be changed by Grid users might bring an important problem of maintaining data consistency among the various replicas distributed in different machines.So the sum of them along with the proper weight (w1,w2) for each factor yields the combined cost (CCi,j) of executing job i in site j.A classification of file placement and replication methods on grids--- Future Generation Computer Systems encounter, slightly, simplistic, clairvoyance, deploy, stringent, concerning, properly,

entirely known to the file placement algorithm.Cooperation between data placement and job scheduling can improve the overall transfer time and have a significant impact on the application makespan as shown in.We conclude that replication policies should rely on a-priori information about file accesses, such as file type or workflow relation.Dynamic replica placement and selection strategies in

are used in data grid to reduce makespan, storage consumption, access latency and network bandwidth.Data replication enhances data availability and thereby increases the system reliability.Managing dynamic architecture of the grid, decision making of replica placement, storage space, cost of replication and selection are some of the issues that impact the performance of the grid.Benefits of data replication strategies include availability, reliability, scalability, adaptability and improved performance.As the name indicates, in dynamic grid, nodes can join and leave the grid anytime.Any replica placement and selection strategy tries to improve one or more of the following parameters: makespan, quality assurance, file missing rate, byte missing rate, communication cost, response time, bandwidth consumption, access latency, load balancing, maintenance cost, job execution time, fault tolerance and strategic replica placement.Identifying Dynamic Replication Strategies for a

bandwidth consumption and access latency in high performance “data grids” where users require remote access to large files.A data grid connects a collection of geographically distributed computer and storage resources that may be located in different parts of a country or even in different countries, and enables users to share data and other resources.The main aims of using replication are to reduce access latency and bandwidth consumption. Replication can also help in load balancing and can improve reliability by creating multiple copies of the same data.Group-Based Management of Distributed File Caches--- Distributed Computing Systems, 2002 mechanism, exploit, inherent, detrimental, preempt, incur, mask, fetch, likelihood, overlapping, subtle,in spite ofcontend withfar enough in advancetake sth for granted(be) superior toDynamic file grouping is an effective mechanism for exploiting the predictability of file access patterns and improving the caching performance of distributed file systems.With our grouping mechanism we establish relationships by observing file access behavior, without relying on inference from file location or content.We group files to reduce access latency. By fetching groups of files, instead of individual files, we increase cache hit rates when groups contain files that are likely to be accessed together.Further experimentation against the same workloads demonstrated that recency was a better estimator of per-file succession likelihood than frequency counts.Job scheduling and data replication on data grids--- Future Generation Computer

time consuming.If a job is scheduled to a site where the required data are present, the job can process data in this site without any transmission delay for getting data from a remote site.RADPA: Reliability-aware Data Placement Algorithm for large-scale network storage systems--- High Performance Computing and Communications, 2009 ever-going, oblivious, exponentially, confront,as a

depicted in Fig.1et al.The volume of data is measured in terabytes and some time in petabytes in many fields.Data replication allows speeding up data access, reducing access latency and increasing data availability.How many suitable replicas of each data should be created in the cloud to meet a reasonable system requirement is an important issue for further research.Where should these replicas be placed to meet the system task fast execution rate and load balancing requirements is another important issue to be thoroughly investigated.As the system maintenance cost will significantly increase with the number of replicas increasing, keeping too many or fixed replicas are not a good choice.Where should these replicas be placed to meet the system task fast execution rate and load balancing requirements is another important issue to be thoroughly investigated.We build up five objectives for optimization which provides us with the advantage that we can search for solutions that yield close to optimal values for these objectives.The shortcoming of them is that they only consider a restricted set of parameters affecting the replication decision. Further, they only focus on the improvement of the system performance and they do not address the energy efficiency issue in data centers.Data node load variance is the standard deviation of data node load of all data nodes in the cloud storage cluster which can be used to represent the degree of load balancing of the system.The advantage of using simulation is that we can easily vary parameters to understand their individual impact on system performance.Throughout the simulation, we assumed "write-once, read-many" data and did not include the consistency or write and update propagations costs in the study.Distributed replica placement algorithms for correlated data--- The Journal of Supercomputing yield, potential, congestion, prolonged, malicious, overhead, conventional, present, propose,

applications are all moving toward serving widely distributed users.Replication techniques have been commonly used to minimize the communication latency by bringing the data close to the clients and improve data availability.Thus, data needs to be carefully placed to avoid unnecessary overhead.These correlations have significant impact on data access patterns.For structured data, data correlated due to the structural relations may be frequently accessed together.Assume that data objects can be clustered into different classes due to user accesses, and whenever a client issues an access request, it will only access data in a single class.One challenge for using centralized replica placement algorithms in a widely distributed system is that a server site has to know the (logical) network topology and the resident set of all structured data sets to make replication decisions.We assume that the data objects accessed by most of the transactions follow certain patterns, which will be stable for some time periods.Locality-aware allocation of multi-dimensional correlated files on thecloud platform--- Distributed and Parallel Databases enormous, retrieve, prevailing, commonly,

platform has attracted devoting research efforts.Currently, most prevailing Cloud file systems allocate data following the principles of fault tolerance and availability, while inter-file correlations, i.e. files correlated with each other, are often neglected.There is a trade-off between data locality and the scale of job parallelism.Although distributing data randomly is expected to achieve the best parallelism, however, such a method may lead to degraded user experiences for introducing extra costs on large volume of remote accesses, especially for many applications that are featured with data locality, e.g., context-aware search, subspace oriented aggregation queries, and etc.However, there must be several application-dependent hot subspaces, under which files are frequently being processed.The problem is how to find a compromised partition solution to well serve the file correlations of different feature subspaces as much as possible.If too many files are grouped together, the imbalance cost would raise and degrade the scale of job parallelism;if files are partitioned into too many small groups, data copying traffic across storage nodes would increase.Instead, our solution is to start from a sub-optimal solution and employ some heuristics to derive a near optimal partition with as less cost as possible.By allocating correlated files together, significant I/O savings can be achieved on reducing the huge cost of random data access over the entire distributed storage network.Big Data Analytics framework for Peer-to-Peer Botnet

Hadoop, Hive and Mahout to provide a scalable implementation of quasi-real-time intrusion detection system.As per the current knowledge of the authors, the area of network security analytics severely

Since ANNs are the best classifiers to model such nonlinear systems, PD patterns can be recognized suitably by ANNs.In other words, when classifier is trained after initial sophistications based on the PRPD patterns extracted from some objects including artificial defects, it can be efficiently used in practical fields to identify the exactly same PD sources by new test data without any iterative process.In pulse shape characterization, some signal processing methods such as Wavelet or Fourier transforms are usually used to extract some features from PD waveshape. These methods are affected by noise and so it is necessary to incorporate some de-noising methods into the pattern recognition process.PD identification is usually performed using PRPD recognition which is not influenced by changing the experimental set up.Partial Discharge Pattern Recognition of Cast Resin CurrentTransformers Using Radial Basis Function Neural Network--- Journal of Electrical Engineering & Technology propose, novel, vital, demonstrate, conduct, significant,This paper proposes a novel pattern recognition approach based on the radial basis function (RBF) neural network for identifying insulation defects of high-voltage electrical apparatus arising from partial discharge (PD).PD measurement and pattern recognition are important tools for improving the reliability of the high-voltage insulation system.。
