84-567: Clients: Same as Google Chrome Google Native Client ( NaCl ) is a discontinued sandboxing technology for running either a subset of Intel x86 , ARM , or MIPS native code, or a portable executable, in a sandbox. It allows safely running native code from a web browser , independent of the user operating system , allowing web apps to run at near-native speeds, which aligns with Google's plans for ChromeOS . It may also be used for securing browser plugins , and parts of other applications or full applications such as ZeroVM . To demonstrate

168-488: A "tips" section that displays hints and tricks for using the browser. Starting with Google Chrome 3.0, users can install themes to alter the appearance of the browser. Many free third-party themes are provided in an online gallery, accessible through a "Get themes" button in Chrome's options. Chrome includes a bookmarks submenu that lists the user's bookmarks, provides easy access to Chrome's Bookmark Manager, and allows

252-498: A browser, Native Client is much more interesting as something that started out as a really pretty darn clever x86 hack in the way that they could sandbox all of this in user mode interestingly. It's now dynamic recompilation, but something that you program in C or C++ and it compiles down to something that's going to be not your -O4 optimization level for completely native code but pretty damn close to native code. You could do all of your evil pointer chasings, and whatever you want to do as

336-502: A built-in ability to enable experimental features. Originally called about:labs , the address was changed to about:flags to make it less obvious to casual users. The desktop edition of Chrome is able to save pages as HTML with assets in a "_files" subfolder, or as unprocessed HTML-only document. It also offers an option to save in the MHTML format. Chrome allows users to make local desktop shortcuts that open web applications in

420-404: A continuous-time model of the actuator hydraulics, allowing the study of switching transients. In signal processing based FDI, some mathematical or statistical operations are performed on the measurements, or some neural network is trained using measurements to extract the information about the fault. A good example of signal processing based FDI is time domain reflectometry where a signal

504-600: A criticism for this change since it limits the number of rules and types of expressions that may be checked by adblockers. Additionally, the prohibition of remotely-hosted code will restrict the ability for adblocking filter lists to be updated independently of the extension itself. The JavaScript virtual machine used by Chrome, the V8 JavaScript engine, has features such as dynamic code generation , hidden class transitions , and precise garbage collection . In 2008, several websites performed benchmark tests using

588-1068: A few feature values from signals, causing a dimensionality reduction from the original signal . By using Convolutional neural networks , the continuous wavelet transform scalogram can be directly classified to normal and faulty classes. Such a technique avoids omitting any important fault message and results in a better performance of fault detection and diagnosis. In addition, by transforming signals to image constructions, 2D Convolutional neural networks can be implemented to identify faulty signals from vibration image features. Deep belief networks , Restricted Boltzmann machines and Autoencoders are other deep neural networks architectures which have been successfully used in this field of research. In comparison to traditional machine learning , due to their deep architecture, deep learning models are able to learn more complex structures from datasets , however, they need larger samples and longer processing time to achieve higher accuracy. Fault Recovery in FDIR

672-458: A license to all content transferred via the Chrome browser. This passage was inherited from the general Google terms of service. Google responded to this criticism immediately by stating that the language used was borrowed from other products, and removed this passage from the Terms of Service. Chrome quickly gained about 1% usage share. After the initial surge, usage share dropped until it hit

756-658: A low of 0.69% in October 2008. It then started rising again and by December 2008, Chrome again passed the 1% threshold. In early January 2009, CNET reported that Google planned to release versions of Chrome for macOS and Linux in the first half of the year. The first official macOS and Linux developer previews of Chrome were announced on June 4, 2009, with a blog post saying they were missing many features and were intended for early feedback rather than general use. In December 2009, Google released beta versions of Chrome for macOS and Linux. Google Chrome 5.0, announced on May 25, 2010,

840-538: A major future update to Chrome's extension API , known as "Manifest V3" (in reference to the manifest file contained within extensions). Manifest V3 is intended to modernize the extension architecture and improve the security and performance of the browser; it adopts declarative APIs to "decrease the need for overly-broad access and enable more performant implementation by the browser", replaces background pages with feature-limited "Service Workers" to reduce resource usage, and prohibits remotely-hosted code. Google faced

924-463: A more simplified 3 dot menu. Starting with Google Chrome 4.1, the application added a built-in translation bar using Google Translate . Language translation is currently available for 52 languages. When Chrome detects a foreign language other than the user's preferred language set during the installation time, it asks the user whether or not to translate. Chrome allows users to synchronize their bookmarks, history, and settings across all devices with

1008-597: A new platform – or porting an old platform into the web [...] it will bring in complexity and security issues, and it will take away focus from the web platform." The second generation of sandboxing developed in Google is gVisor . It is intended to replace NaCl in Google Cloud , to be more exact in Google App Engine . Google has also been promoting WebAssembly . Google Chrome Google Chrome

1092-513: A number of other open-source projects. The V8 JavaScript virtual machine was considered a sufficiently important project to be split off (as was Adobe /Mozilla's Tamarin ) and handled by a separate team in Denmark coordinated by Lars Bak . According to Google, existing implementations were designed "for small programs, where the performance and interactivity of the system weren't that important", but web applications such as Gmail "are using

1176-521: A rotating machine are strongly related to its rotational speed, it can be said that they are time-variant signals in nature. These time-variant features carry the machine fault signatures. Consequently, how these features are extracted and interpreted is important to research and industrial applications. The most common method used in signal analysis is the FFT , or Fourier transform. The Fourier transform and its inverse counterpart offer two perspectives to study

1260-548: A score of 600+ failed, while Internet Explorer 10 had a score of 7 failed. In 2011, on the official CSS 2.1 test suite by standardization organization W3C , WebKit, the Chrome rendering engine, passed 89.75% (89.38% out of 99.59% covered) CSS 2.1 tests. On the HTML5 web standards test, Chrome 41 scored 518 out of 555 points, placing it ahead of the five most popular desktop browsers. Chrome 41 on Android scored 510 out of 555 points. Chrome 44 scored 526, only 29 points less than

1344-466: A signal: via the time domain or via the frequency domain. The FFT -based spectrum of a time signal shows us the existence of its frequency contents. By studying these and their magnitude or phase relations, we can obtain various types of information, such as harmonics , sidebands , beat frequency , bearing fault frequency and so on. However, the FFT is only suitable for signals whose frequency contents do not change over time; however, as mentioned above,

1428-470: A software demonstration that pushed Schmidt into making Chrome a core business priority, which resulted in commercial success. Because of the proliferation of Chrome, Google has expanded the "Chrome" brand name to other products. These include not just ChromeOS but also Chromecast , Chromebook , Chromebit , Chromebox , and Chromebase . Google chief executive Eric Schmidt opposed the development of an independent web browser for six years. He stated that "at

1512-452: A to-the-metal game developer." Other IT professionals were more critical of this sandboxing technology as it had substantial or substantive interoperability issues. Mozilla 's vice president of products, Jay Sullivan , said that Mozilla has no plans to run native code inside the browser, as "These native apps are just little black boxes in a webpage. [...] We really believe in HTML, and this

1596-418: A version of Chrome for augmented reality and virtual reality devices. Google Chrome features a minimalistic user interface, with its user-interface principles later being implemented into other browsers. For example, the merging of the address bar and search bar into the omnibox or omnibar Chrome also has a reputation for strong browser performance. The first release of Google Chrome passed both

1680-418: A version of Chrome on Windows which added hardware-accelerated H.264 video decoding. In October 2013, Cisco announced that it was open-sourcing its H.264 codecs, and it would cover all fees required. On February 7, 2012, Google launched Google Chrome Beta for Android 4.0 devices. On many new devices with Android 4.1 or later preinstalled, Chrome is the default browser. In May 2017, Google announced

1764-499: A window separate from Chrome, and look more like native applications. Announced on December 7, 2010, the Chrome Web Store allows users to install web applications as extensions to the browser, although most of these extensions function simply as links to popular web pages or games, some of the apps like Springpad do provide extra features like offline access. The themes and extensions have also been tightly integrated into

1848-429: Is 0x7F 'E' 'L' 'F', which is ELF . In Chrome, they are translated to architecture-specific executables so that they can be run. NaCl uses software fault detection and isolation for sandboxing on x86-64 and ARM. The x86-32 implementation of Native Client is notable for its novel sandboxing method, which makes use of the x86 architecture's rarely used segmentation facility . Native Client sets up x86 segments to restrict

1932-530: Is a web browser developed by Google . It was first released in 2008 for Microsoft Windows , built with free software components from Apple WebKit and Mozilla Firefox . Versions were later released for Linux , macOS , iOS , iPadOS , and also for Android , where it is the default browser. The browser is also the main component of ChromeOS , where it serves as the platform for web applications . Most of Chrome's source code comes from Google's free and open-source software project Chromium , but Chrome

2016-678: Is a cross-platform API for Native Client-secured web browser plugins, first based on Netscape's NPAPI , then rewritten from scratch. It was used in Chromium and Google Chrome to enable the PPAPI version of Adobe Flash and the built-in PDF viewer. On 12 August 2009, a page on Google Code introduced a new project, Pepper, and the associated Pepper Plugin API (PPAPI), "a set of modifications to NPAPI to make plugins more portable and more secure". This extension

2100-689: Is a field of mechanical engineering concerned with finding faults arising in machines. A particularly well developed part of it applies specifically to rotating machinery, one of the most common types encountered. To identify the most probable faults leading to failure, many methods are used for data collection, including vibration monitoring, thermal imaging , oil particle analysis, etc. Then these data are processed utilizing methods like spectral analysis , wavelet analysis , wavelet transform, short term Fourier transform, Gabor Expansion, Wigner-Ville distribution (WVD), cepstrum, bispectrum, correlation method, high resolution spectral analysis, waveform analysis (in

2184-410: Is also dominant on smartphones. With a market share of 65% across all platforms combined, Chrome is the most used web browser in the world today. Google Chief Executive Eric Schmidt was previously involved in the " browser wars ", a part of U.S. corporate history , and opposed the expansion of the company into such a new area. However, Google co-founders Sergey Brin and Larry Page spearheaded

2268-478: Is an architecture-independent version. PNaCl apps are compiled ahead-of-time . PNaCl is recommended over NaCl for most use cases. The general concept of NaCl (running native code in web browser) has been implemented before in ActiveX , which, while still in use, has full access to the system (disk, memory, user-interface, registry, etc.). Native Client avoids this issue by using sandboxing. An alternative by Mozilla

2352-400: Is designed specifically to ease implementing out-of- process plugin execution. Further, the goals of the project are to provide a framework for making plugins fully cross-platform. Topics considered include: The Pepper API also supports Gamepads (version 19) and WebSockets (version 18). As of 13 May 2010, Google's open source browser, Chromium , was the only web browser to use

2436-457: Is internally tested with unit testing , automated testing of scripted user actions, fuzz testing , as well as WebKit's layout tests (99% of which Chrome is claimed to have passed), and against commonly accessed websites inside the Google index within 20–30 minutes. Google created Gears for Chrome, which added features for web developers typically relating to the building of web applications, including offline support. Google phased out Gears as

2520-548: Is licensed as proprietary freeware . WebKit was the original rendering engine , but Google eventually forked it to create the Blink engine; all Chrome variants except iOS used Blink as of 2017. As of April 2024 , StatCounter estimates that Chrome has a 65% worldwide browser market share (after peaking at 72.38% in November 2018) on personal computers (PC), is most used on tablets (having surpassed Safari ), and

2604-505: Is sent down a cable or electrical line and the reflected signal is compared mathematically to original signal to identify faults. Spread Spectrum Time Domain Reflectometry, for instance, involves sending down a spread spectrum signal down a wire line to detect wire faults. Several clustering methods have also been proposed to identify the novel fault and segment a given signal into normal and faulty segments. Machine fault diagnosis

2688-408: Is that instead of finding the most likely model, these techniques omit the models, which are not compatible with data. The example shown in the figure on the right illustrates a model-based FDI technique for an aircraft elevator reactive controller through the use of a truth table and a state chart. The truth table defines how the controller reacts to detected faults, and the state chart defines how

2772-537: Is used on large datasets . Since k NN is not able to automatically extract the features to overcome the curse of dimensionality , so often some data preprocessing techniques like Principal component analysis (PCA), Linear discriminant analysis (LDA) or Canonical correlation analysis (CCA) accompany it to reach a better performance. In many industrial cases, the effectiveness of k NN has been compared with other methods, specially with more complex classification models such as Support Vector Machines (SVMs), which

2856-413: Is where we want to focus." Mozilla's Christopher Blizzard criticized NaCl, claiming that native code cannot evolve in the same way that the source code-driven web can. He also compared NaCl to Microsoft's ActiveX technology, plagued with DLL Hell . Håkon Wium Lie , Opera's CTO, believed that "NaCl seems to be 'yearning for the bad old days, before the web'", and that "Native Client is about building

2940-416: Is widely used in this field. Thanks to their appropriate nonlinear mapping using kernel methods , SVMs have an impressive performance in generalization, even with small training data. However, general SVMs do not have automatic feature extraction themselves and just like k NN , are often coupled with a data pre-processing technique. Another drawback of SVMs is that their performance is highly sensitive to

3024-659: The Acid1 and Acid2 tests. Beginning with version 4.0, Chrome has passed all aspects of the Acid3 test. As of May 2011 , Chrome has very good support for JavaScript/ ECMAScript according to Ecma International 's ECMAScript standards conformance Test 262 (version ES5.1 May 18, 2012). This test reports as the final score the number of tests a browser failed; hence lower scores are better. In this test, Chrome version 37 scored 10 failed/11,578 passed. For comparison, Firefox 19 scored 193 failed/11,752 passed and Internet Explorer 9 had

3108-524: The GNU toolchain , specifically GNU Compiler Collection (GCC), GNU Binutils , and LLVM . Native Client is licensed under a BSD-style license . Native Client uses Newlib as its C library , but a port of GNU C Library (GNU libc) is also available. NaCl denotes sodium chloride , common table salt ; as a pun , the name of pepper was also used. Pepper API is a cross-platform, open-source API for creating Native Client modules. Pepper Plugin API, or PPAPI

3192-842: The Google Chrome web browser since version 14, and has been enabled by default since version 31, when the Portable Native Client (PNaCl, pronounced: pinnacle) was released. An ARM implementation was released in March 2010. x86-64 , IA-32 , and MIPS were also supported. To run an application portably under PNaCl, it must be compiled to an architecture-agnostic and stable subset of the LLVM intermediate representation bytecode . The executables are called PNaCl executables (pexes). The PNaCl Toolchain makes .pexe files; NaCl Toolchain .nexe files. The magic number of .nexe files

3276-800: The Omnibox . The Omnibox is a URL box that combines the functions of both the address bar and search box. If a user enters the URL of a site previously searched from, Chrome allows pressing Tab to search the site again directly from the Omnibox. When a user starts typing in the Omnibox, Chrome provides suggestions for previously visited sites (based on the URL or in-page text), popular websites (not necessarily visited before – powered by Google Instant ), and popular searches. Although Instant can be turned off, suggestions based on previously visited sites cannot be turned off. Chrome will also autocomplete

3360-619: The SunSpider JavaScript Benchmark tool as well as Google's own set of computationally intense benchmarks, which include ray tracing and constraint solving . They unanimously reported that Chrome performed much faster than all competitors against which it had been tested, including Safari (for Windows), Firefox 3.0 , Internet Explorer 7 , Opera, and Internet Explorer 8 . { However, on October 11, 2010, independent tests of JavaScript performance, Chrome has been scoring just behind Opera's Presto engine since it

3444-412: The user interface chrome . The browser was first publicly released, officially as a beta version , on September 2, 2008, for Windows XP and newer, and with support for 43 languages, and later as a "stable" public release on December 11, 2008. On that same day, a CNET news item drew attention to a passage in the Terms of Service statement for the initial beta release, which seemed to grant to Google

3528-449: The Chrome spirit – to make the web quicker, lighter, and easier for all." On January 11, 2011, the Chrome product manager, Mike Jazayeri, announced that Chrome would remove H.264 video codec support for its HTML5 player, citing the desire to bring Google Chrome more in line with the currently available open codecs available in the Chromium project, which Chrome is based on. Despite this, on November 6, 2012, Google released

3612-631: The Google Chrome Extensions Gallery beta began with approximately 300 extensions. It was launched on January 25, 2010, along with Google Chrome 4.0, containing approximately 1500 extensions. In 2014, Google started preventing some Windows users from installing extensions not hosted on the Chrome Web Store. The following year Google reported a "75% drop in customer support help requests for uninstalling unwanted extensions" which led them to expand this restriction to all Windows and Mac users. In October 2018, Google announced

3696-464: The Google Chrome Extensions Gallery. Some extensions focus on providing accessibility features. Google Tone is an extension developed by Google that when enabled, can use a computer's speakers to exchange URLs with nearby computers with an Internet connection that have the extension enabled as well. On September 9, 2009, Google enabled extensions by default on Chrome's developer channel, and provided several sample extensions for testing. In December,

3780-480: The New Tab Page was updated to allow users to hide thumbnails they did not want to appear. Starting in version 3.0, the New Tab Page was revamped to display thumbnails of the eight most visited websites. The thumbnails could be rearranged, pinned, and removed. Alternatively, a list of text links could be displayed instead of thumbnails. It also features a "Recently closed" bar that shows recently closed tabs and

3864-729: The URLs of sites visited often. If a user types keywords into the Omnibox that do not match any previously visited websites and presses enter, Chrome will conduct the search using the default search engine. One of Chrome's differentiating features is the New Tab Page , which can replace the browser home page and is displayed when a new tab is created. Originally, this showed thumbnails of the nine most visited websites, along with frequent searches, recent bookmarks, and recently closed tabs; similar to Internet Explorer and Firefox with Google Toolbar , or Opera's Speed Dial . In Google Chrome 2.0,

3948-421: The bearing's damaged state is not enough for precision maintenance purposes. The root cause needs to be identified and remedied. If this is not done, the replacement bearing will soon wear out for the same reason and the machine will suffer more damage, remaining dangerous. Of course, the cause may also be visible as a result of the spectral analysis undertaken at the data-collection stage, but this may not always be

4032-520: The browser installed by sending and receiving data through a chosen Google Account, which in turn updates all signed-in instances of Chrome. This can be authenticated either through Google credentials, or a sync passphrase. For web developers, Chrome has an element inspector which allows users to look into the DOM and see what makes up the webpage. Chrome has special URLs that load application-specific pages instead of websites or files on disk. Chrome also has

4116-732: The browser. The browser, when opened in this way, contains none of the regular interface except for the title bar, so as not to "interrupt anything the user is trying to do". This allows web applications to run alongside local software (similar to Mozilla Prism and Fluid ). This feature, according to Google, would be enhanced with the Chrome Web Store , a one-stop web-based web applications directory which opened in December 2010. In September 2013, Google started making Chrome apps "For your desktop". This meant offline access, desktop shortcuts, and less dependence on Chrome—apps launch in

4200-545: The case. The most common technique for detecting faults is the time-frequency analysis technique. For a rotating machine, the rotational speed of the machine (often known as the RPM ), is not a constant, especially not during the start-up and shutdown stages of the machine. Even if the machine is running in the steady state, the rotational speed will vary around a steady-state mean value, and this variation depends on load and other factors. Since sound and vibration signals obtained from

4284-399: The comic available on Google Books , and mentioned it on their official blog along with an explanation for the early release. The product was named "Chrome" as an initial development project code name , because it is associated with fast cars and speed. Google kept the development project name as the final release name, as a "cheeky" or ironic moniker, as one of the main aims was to minimize

4368-448: The complex relations (which generally exist inherently in fault detection and diagnosis problems) and are easy to operate. Another advantage of ANNs is that they perform automatic feature extraction by allocating negligible weights to the irrelevant features, helping the system to avoid dealing with another feature extractor. However, ANNs tend to over-fit the training set, which will have consequences of having poor validation accuracy on

4452-407: The controller switches between the different modes of operation (passive, active, standby, off, and isolated) of each actuator. For example, if a fault is detected in hydraulic system 1, then the truth table sends an event to the state chart that the left inner actuator should be turned off. One of the benefits of this model-based FDI technique is that this reactive controller can also be connected to

4536-403: The cost of what is to be avoided in the first place, requires an effective scheme of applying them. This is the subject of maintenance, repair and operations ; the different strategies include: In fault detection and diagnosis, mathematical classification models which in fact belong to supervised learning methods, are trained on the training set of a labeled dataset to accurately identify

4620-511: The end of 2020. By January 2021, Adobe Flash Player, Google Chrome, Firefox, Safari, and Windows received updates disabling or entirely removing Flash. One website used NaCL on the server to let users experiment with the Go programming language from their browsers. Some groups of browser developers supported the Native Client technology while others did not. Chad Austin (of IMVU ) praised

4704-452: The evolution of the conventional FFT , then quadratic time frequency analysis would be the power spectrum counterpart. Quadratic algorithms include the Gabor spectrogram, Cohen's class and the adaptive spectrogram. The main advantage of time frequency analysis is discovering the patterns of frequency changes, which usually represent the nature of the signal. As long as this pattern is identified

4788-486: The fault detection and diagnosis in industries such as gearbox , machinery parts (i.e. mechanical bearings ), compressors , wind and gas turbines and steel plates . With the research advances in ANNs and the advent of deep learning algorithms using deep and complex layers, novel classification models have been developed to cope with fault detection and diagnosis. Most of the shallow learning models extract

4872-472: The frequency contents of the sound and vibration signals obtained from a rotating machine are very much time-dependent. For this reason, FFT -based spectra are unable to detect how the frequency contents develop over time. To be more specific, if the RPM of a machine is increasing or decreasing during its startup or shutdown period, its bandwidth in the FFT spectrum will become much wider than it would be simply for

4956-517: The initial parameters, particularly to the kernel methods , so in each signal dataset , a parameter tuning process is required to be conducted first. Therefore, the low speed of the training phase is a limitation of SVMs when it comes to its usage in fault detection and diagnosis cases. Artificial Neural Networks (ANNs) are among the most mature and widely used mathematical classification algorithms in fault detection and diagnosis. ANNs are well-known for their efficient self-learning capabilities of

5040-470: The machine fault associated with this pattern can be identified. Another important use of time frequency analysis is the ability to filter out a particular frequency component using a time-varying filter. In practice, model uncertainties and measurement noise can complicate fault detection and isolation. As a result, using fault diagnostics to meet industrial needs in a cost-effective way, and to reduce maintenance costs without requiring more investments than

5124-703: The maximum score. By default, the main user interface includes back, forward, refresh/cancel and menu buttons. A home button is not shown by default, but can be added through the Settings page to take the user to the new tab page or a custom home page. Tabs are the main component of Chrome's user interface and have been moved to the top of the window rather than below the controls. This subtle change contrasts with many existing tabbed browsers which are based on windows and contain tabs. Tabs, with their state, can be transferred seamlessly between window containers by dragging. Each tab has its own set of controls, including

5208-542: The memory range that the sandboxed code can access. It uses a code verifier to prevent use of unsafe instructions such as those that perform system calls. To prevent the code from jumping to an unsafe instruction hidden in the middle of a safe instruction, Native Client requires that all indirect jumps be jumps to the start of 32-byte-aligned blocks, and instructions are not allowed to straddle these blocks. Because of these constraints, C and C++ code must be recompiled to run under Native Client, which provides customized versions of

5292-498: The new browser plug-in model. As of 2020, Pepper is supported by Chrome, Chromium and Blink layout engine-based browsers such as Opera and Microsoft Edge. In August 2020, Google announced that support for PPAPI would be removed from Google Chrome and Chromium in June 2022. Firefox developers stated in 2014 that they would not support Pepper, as there were no full specification of the API beyond its implementation in Chrome, which itself

5376-459: The new store, allowing users to search the entire catalog of Chrome extras. The Chrome Web Store was opened on February 11, 2011, with the release of Google Chrome 9.0. Browser extensions are able to modify Google Chrome. They are supported by the browser's desktop edition, but not on mobile. These extensions are written using web technologies like HTML , JavaScript, and CSS . They are distributed through Chrome Web Store, initially known as

5460-563: The quadratic method describes the energy distribution of a signal in the joint time frequency domain, which is useful for analysis, classification, and detection of signal features, phase information is lost in the quadratic time-frequency representation; also, the time histories cannot be reconstructed with this method. The short-term Fourier transform ( STFT ) and the Gabor transform are two algorithms commonly used as linear time-frequency methods. If we consider linear time-frequency analysis to be

5544-518: The readiness of the technology, on 9 December 2011, Google announced the availability of several new Chrome-only versions of games known for their rich and processor -intensive graphics , including Bastion (no longer supported on the Chrome Web Store ). NaCl runs hardware-accelerated 3D graphics (via OpenGL ES 2.0), sandboxed local file storage, dynamic loading , full screen mode, and mouse capture. There were also plans to make NaCl available on handheld devices. Portable Native Client (PNaCl)

5628-487: The redundancies, faults and anomalous samples. During the past decades, there are different classification and preprocessing models that have been developed and proposed in this research area. K -nearest-neighbors algorithm ( k NN) is one of the oldest techniques which has been used to solve fault detection and diagnosis problems. Despite the simple logic that this instance-based algorithm has, there are some problems with large dimensionality and processing time when it

5712-514: The same functionality became available in the HTML5 standards. In March 2011, Google introduced a new simplified logo to replace the previous 3D logo that had been used since the project's inception. Google designer Steve Rura explained the company reasoning for the change: "Since Chrome is all about making your web experience as easy and clutter-free as possible, we refreshed the Chrome icon to better represent these sentiments. A simpler icon embodies

5796-473: The second quarter of 2019, it has been removed in June 2022 (together with Chrome Apps ). Native Client was an open-source project developed by Google . Games such as Quake , XaoS , Battle for Wesnoth , Doom , Lara Croft and the Guardian of Light , From Dust , and MAME , as well as the sound processing system Csound , have been ported to Native Client. Native Client has been available in

5880-440: The steady state. Hence, in such a case, the harmonics are not so distinguishable in the spectrum. The time frequency approach for machine fault diagnosis can be divided into two broad categories: linear methods and the quadratic methods. The difference is that linear transforms can be inverted to construct the time signal, thus, they are more suitable for signal processing, such as noise reduction and time-varying filtering. Although

5964-442: The system is used to decide about the occurrence of fault. The system model may be mathematical or knowledge based. Some of the model-based FDI techniques include observer-based approach, parity-space approach, and parameter identification based methods. There is another trend of model-based FDI schemes, which is called set-membership methods. These methods guarantee the detection of fault under certain conditions. The main difference

6048-499: The time domain, because spectral analysis usually concerns only frequency distribution and not phase information) and others. The results of this analysis are used in a root cause failure analysis in order to determine the original cause of the fault. For example, if a bearing fault is diagnosed, then it is likely that the bearing was not itself damaged at installation, but rather as the consequence of another installation error (e.g., misalignment) which then led to bearing damage. Diagnosing

6132-409: The time that Google was hiring former Microsoft web developers among others. It also came shortly after the release of Mozilla Firefox 1.0, which was surging in popularity and taking market share from Internet Explorer , which had noted security problems.

6216-440: The time, Google was a small company", and he did not want to go through "bruising browser wars". Company co-founders Sergey Brin and Larry Page hired several Mozilla Firefox developers and built a demonstration of Chrome. Afterwards, Schmidt said, "It was so good that it essentially forced me to change my mind." In September 2004, rumors of Google building a web browser first appeared.

6384-523: The validation set. Hence, often, some regularization terms and prior knowledge are added to the ANN model to avoid over-fitting and achieve higher performance. Moreover, properly determining the size of the hidden layer needs an exhaustive parameter tuning, to avoid poor approximation and generalization capabilities. In general, different SVMs and ANNs models (i.e. Back-Propagation Neural Networks and Multi-Layer Perceptron ) have shown successful performances in

6468-401: The way Native Client can bring high-performance applications to the web (with about 5% penalty compared to native code) in a secure way, while also accelerating the evolution of client-side applications by giving a choice of the programming language used (besides JavaScript ). Id Software 's John D. Carmack praised Native Client at QuakeCon 2012, saying: "if you have to do something inside

6552-638: The web browser to the fullest when it comes to DOM manipulations and JavaScript", and therefore would significantly benefit from a JavaScript engine that could work faster. Chrome initially used the WebKit rendering engine to display web pages. In 2013, they forked the WebCore component to create their own layout engine Blink. Based on WebKit, Blink only uses WebKit's "WebCore" components, while substituting other components, such as its own multi-process architecture, in place of WebKit's native implementation. Chrome

6636-565: Was asm.js , which also allows applications written in C or C++ to be compiled to run in the browser and also supports ahead-of-time compilation, but is a subset of JavaScript and hence backwards-compatible with browsers that do not support it directly. On 12 October 2016, a comment on the Chromium issue tracker indicated that Google's Pepper and Native Client teams had been destaffed. On 30 May 2017, Google announced deprecation of PNaCl in favor of WebAssembly . Although initially Google planned to remove PNaCl in first quarter of 2018, and later in

6720-493: Was "largely developed" in Google's Kitchener office. The release announcement was originally scheduled for September 3, 2008, and a comic by Scott McCloud was to be sent to journalists and bloggers explaining the features within the new browser. Copies intended for Europe were shipped early and German blogger Philipp Lenssen of Google Blogoscoped made a scanned copy of the 38-page comic available on his website after receiving it on September 1, 2008. Google subsequently made

6804-521: Was designed for use with Blink layout engine only, and had private APIs specific to the Flash Player plugin which were not documented. In October 2016 Mozilla announced that it had re-considered and was exploring whether to incorporate the Pepper API and PDFium in future releases of Firefox, however no such steps were taken. In July 2017, Adobe deprecated Flash and announced its end-of-life in

6888-529: Was representative of real programs. He stated that Firefox 3.0 performed poorly on recursion -intensive benchmarks, such as those of Google, because the Mozilla team had not implemented recursion-tracing yet. Two weeks after Chrome's launch in 2008, the WebKit team announced a new JavaScript engine, SquirrelFish Extreme , citing a 36% speed improvement over Chrome's V8 engine. Fault detection and isolation In model-based FDI techniques some model of

6972-435: Was the first stable release to support all three platforms. Chrome was one of the twelve browsers offered on BrowserChoice.eu to European Economic Area users of Microsoft Windows in 2010. Chrome was assembled from 25 different code libraries from Google and third parties such as Mozilla 's Netscape Portable Runtime , Network Security Services , NPAPI (dropped as of version 45), Skia Graphics Engine , SQLite , and

7056-427: Was updated in version 10.5. On September 3, 2008, Mozilla responded by stating that their own TraceMonkey JavaScript engine (then in beta), was faster than Chrome's V8 engine in some tests. John Resig , Mozilla's JavaScript evangelist, further commented on the performance of different browsers on Google's own suite, commenting on Chrome's "decimating" of the other browsers, but he questioned whether Google's suite
