Lab testing data or data from product use in the field can be used to further refine your MTBF analysis. As more and more data is acquired, the failure rate assessments will become more accurate. The minimum you need to start your MTBF analysis is a listing of components, which is commonly available from BOMs.Īs data parameters become finalized during the design stage, the Reliability Prediction analysis can be updated. When using Reliability Prediction software, accepted default values are used for unknown data parameters. It is important to note that detailed data such as operating stresses of all the system components is not required in order to begin MTBF analysis. Much of this data can be obtained from product design drawings, BOMs (Bill of Materials), or from design engineers. If available, lab test data and/or field data (such as accumulated in CAPA or FRACAS).The operating stresses of the components, such as operating voltages and currents.The operating conditions for your product, such as the environment and temperature.The components that are included in each subsystem or unit of your product.The overall structure or design of the system or product you are analyzing.To evaluate your system MTBF using Reliability Prediction techniques, the first step is to acquire all the necessary information about your product or system. Select which Reliability Prediction standard to use.The six-step process for MTBF analysis is: This step-by-step process can also be done iteratively, so that as the product under analysis evolves and changes, the same steps can be repeated to refine the MTBF results. When using Reliability Prediction software tools for MTBF analyses, there is a straightforward, step-by-step process to follow. What are the Steps for Performing MTBF Analysis? Most commonly, the term MTBF analysis is used in reference to the analysis performed using Reliability Prediction standards, which will be the focus of this article. Notably, Reliability Block Diagram (RBD) uses high-powered mathematical techniques to model complex systems using block diagrams. For example, Weibull analysis predicts failure trends based on life data and ALT (Accelerated Life Testing) analysis predicts failure trends based on test data. Other reliability engineering tools also provide valuable ways to assess MTBF. Reliability Prediction software is the most effective way to calculate failure rate and MTBF. Because MTBF analysis using Reliability Prediction is a detailed, mathematical-based methodology, software tools are key to efficient analyses. Reliability Prediction analysis is almost exclusively performed using a software package expressly designed for that purpose. The results of Reliability Prediction analyses are failure rate, MTBF, and other related reliability metrics. Reliability Predictions are used to predict the failure profiles of devices in the constant failure rate portion of the product lifecycle. Reliability Predictions are often used in product design and development as part of reliability and quality continuous improvement efforts. This is why Reliability Prediction analysis is a valuable method for performing MTBF analysis. The most well-known and widely used approach for failure rate analysis is Reliability Prediction. Failure rates of electromechanical systems can be computed using analytical techniques and methodologies well-known and established in the reliability engineering field. How is MTBF Calculated?ĭue to the relationship between failure rate and MTBF, techniques that compute failure rates can be used for MTBF analysis. So, if I know the failure rate of my system is 500 FPMH (failures per million hours), then the MTBF of my system is equal to 1 / 500 failures / 1,000,000 hours, or 2000 hours. In other words, if the failure rate is known, then MTBF is equal to 1 / failure rate. In this timeframe, there is a relationship between MTBF and failure rate: MTBF is the inverse of failure rate. The useful life section is the central and longest portion of the product lifecycle as described by the bathtub curve. MTBF can be computed using the failure rate of a system in its useful life period, or the part of the product lifecycle where the failure rate of the system is constant. However, this is just a predicted or estimated value, it does not indicate that the system will fail precisely at 1000 hours! What is MTBF? For example, an MTBF of 1000 hours indicates that a system, on average, will successfully operate for 1000 hours before experiencing a failure. It is commonly expressed in terms of hours. It is the average amount of time a repairable system can be expected to operate between failures. MTBF is a useful unit of measure for evaluating failure characteristics. MTBF analysis is used to assess the MTBF, or Mean Time Between Failures, of a system or product.

"Only scribes and painters of exceptional skill would have been entrusted with its use," says Alison Beach of Ohio State University, a historian on the project. The use of ultramarine pigment made from lapis lazuli was reserved, along with gold and silver, for the most luxurious manuscripts. "Based on the distribution of the pigment in her mouth, we concluded that the most likely scenario was that she was herself painting with the pigment and licking the end of the brush while painting," states co-first author Monica Tromp of the Max Planck Institute for the Science of Human History. "We examined many scenarios for how this mineral could have become embedded in the calculus on this woman's teeth," explains Radini. Careful analysis using a number of different spectrographic methods - including energy dispersive X-ray spectroscopy (SEM-EDS) and micro-Raman spectroscopy - revealed the blue pigment to be made from lapis lazuli. "It came as a complete surprise - as the calculus dissolved, it released hundreds of tiny blue particles," recalls co-first author Anita Radini of the University of York. The only remarkable aspect to her remains was the blue particles found in her teeth. She had no particular skeletal pathologies, nor evidence of trauma or infection. She was 45-60 years old when she died around 1000-1200 AD. One woman in the cemetery was found to have numerous flecks of blue pigment embedded within her dental calculus. The monastery is believed to have housed approximately 14 religious women from its founding until its destruction by fire following a series of 14th century battles. The earliest known written records from the monastery date to 1244 AD. Few records remain of the monastery and its exact founding date is not known, although a women's community may have formed there as early as the 10th century AD. Their analysis suggests that the woman was likely a painter of richly illuminated religious texts.Īs part of a study analyzing dental calculus - tooth tartar or dental plaque that fossilizes on the teeth during life - researchers examined the remains of individuals who were buried in a medieval cemetery associated with a women's monastery at the site of Dalheim in Germany. Follow him on Twitter at on Faceboo k.In a study published in Science Advances, an international team of researchers led by the Max Planck Institute for the Science of Human History and the University of York shed light on the role of women in the creation of such manuscripts with a surprising discovery - the identification of lapis lazuli pigment embedded in the calcified dental plaque of a middle-aged woman buried at a small women's monastery in Germany around 1100 AD. 1450)īased in Seoul, Colin Marshall writes and broadcasts on cities and culture.

How the Brilliant Colors of Medieval Illuminated Manuscripts Were Made with Alchemyīehold the Beautiful Pages from a Medieval Monk’s Sketchbook: A Window Into How Illuminated Manuscripts Were Made (1494) To fully understand the making of the devices we use to read electronically today would require years and years of study, and so there’s something satisfying in the fact that we can grasp so much about the making of illuminated manuscripts with relative ease: see, for example, the two-minute Getty video just above, “The Structure of a Medieval Manuscript.” A fuller understanding of the nature of illuminated manuscripts, both in the sense of their construction and their place in society, makes for a fuller understanding of how rare the chance was to own beautiful books of their kind in their own time - and how much rarer the exact combination of skills needed to create that beauty. Most of us in the developed world can now buy one of those, but the non-institutional patrons willing and able to commission the most splendid illuminated manuscripts in the Middle Ages and early Renaissance included mostly “society’s rulers: emperors, kings, dukes, cardinals, and bishops.” Some illuminated manuscripts also bear elaborate cover designs sculpted of precious metal, but even without those, these elaborate books - what with all the art and craft that went into them, not to mention all those pricey materials - came out even more valuable, at the time, than even the most coveted laptop, phone, reader, or other consumer electronic device today.

I don’t know if it’s a bug or what but if you want to create a component of a not 3D object like a surface or coplanar lines you must group them first and then create a component. We've got here a door that opens and closes, a window that slides open, and a this 3d n. Learn how to then make the new object and. What I’d like to do is put a chart in the file. Learn how to duplicate the existing dynamic component and make the new instance and any component children unique. If you want, you can double-click your new layer to rename it. Click the Add Layer button to add a new layer to the Layers list. They come in about 8 colors and have options like toe-kicks and different marble tops. Follow these steps to add a layer to your SketchUp file: Choose WindowLayers. I searched quite a bit about spreadsheets and Excel, etc., and couldn’t find what I’m looking info on. Also on the components tray you will find the components you create on your file, even if you’ve deleted them, as long as you haven’t purged your model. In this video I teach you how to make these three dynamic components. I’m new to SketchUp so I don’t yet know it’s more sophisticated capabilities. Select the group or component and open Entity Info to check that the selection is a solid. When you finished with that you accept and close the window the cube you created is still on your workspace but now it’s a component, you can check that by selecting it and verifying on the entity info tray. All SketchUp groups and components should form watertight solids. When you create a component on your workspace it stays there, if you make a cube for example, select it and create a component, a window will pop up, there you can rename the component, it is named as component 1, 2, 3… by default depending on the components you’ve created using the default name, you can also change the origin of the component among other settings. I have colors on all four sides, a pattern on two sides, and on one of the non-pattern / non-end sides I want to draw an arrow that will grow or shrink proportionately to the size of the component. When you close a component you’ve made how do you add it into the drawing you making? I’m creating a simple rectangular solid in SketchUp Pro 2022 (think: rectangular box) and want to make it a dynamic component so I can change the X/Y/Z dimensions on the fly. The rear of the handset is home to the 8.1 megapixel camera, which also support video recording at resolutions of up to 720p (HD). There are plenty of other apps, including a uPnP media server that allows you to share content from the phone over Wi-Fi with other devices like Sony TVs and the PS3, as well as apps for Sony’s Qriocity Music and Movie subscription services. In fact, Facebook integration is tightly woven into the phone, as friends’ birthdays and other events are automatically added to your calendar. This is essentially a graphical, unified inbox that shows Facebook updates, missed calls and text messages as a 3D picture stack with text superimposed over the top.Īnother neat feature is the way the phone’s media gallery pulls in pictures and videos from Facebook and displays them alongside content that’s stored locally. You’ll also find Sony Ericsson’s Timescape application in the App Drawer. For example, in this app the Now Playing screen has a Like button that lets you post music recommendations to your Facebook page or you can hit the infinity icon to search for lyrics or call up the artist’s Wikipedia page. These include a much better music player than the standard Android version. Sony Ericsssn has added a number of its own apps into the mix. A button on the bottom left also lets you automatically sort them by alphabetical order, most used or most recently installed. Apps are arranged across a series of sliding panels, and if you press the a button in the bottom right hand corner they start to jiggle, indicating that you can now move them around to re-arrange them as you like. Tap the menu button and you’re taken to the app drawer, which has had a bit of a make over. As with the vanilla version of Android, there are a number of homescreen panels that you move between by swiping let or right, and these can be populated with a range of different widgets. Like the other models in the Xperia stable, this phone runs on version 2.3 of Android, and Sony Ericsson has added its own custom user interface over the top.įor example, you unlock the home screen by swiping a slide switch from left to right, in much the same way as you do on the iPhone. However, Sony Ericsson does include a 4GB microSD memory card as part of the pack, which provides enough room for storing music and video files. There’s 1GB of storage built-in, although only around 300MB of this is free for you to use, as the rest is taken up by the pre-installed apps and other gubbins. Speed certainly isn’t an issue as it zips through most tasks with ease. The ray runs on a 1Ghz Snapdragon processor and has 512MB of RAM. You can easily change this in the Settings page, but the full portrait Qwerty keyboard is tricky to type on due to the limited space available. The onscreen keyboard is also very cramped in portrait mode – so cramped in fact, that by default Sony Ericsson has set it to a numerical-style keypad. The ray has a 3.3inch capacitive display, but while its resolution of 854×480 pixels ensures text and graphics do look very sharp and crisp, on a display this ‘small’, its narrowness makes using the web browser feel quite awkward, and in portrait mode columns of text look just a little bit too thin. The narrower form factor does help the phone look and feel quite small and slim, but it’s a bit of a problem when it comes to the screen. On the plus side, though, there is a standard headphone jack at the top, while charging and syncing are via a normal micro USB port. Sadly there’s no dedicated camera button, which is a bit of a shame. On the right hand side you’ll find a volume rocker switch, while the front houses the home button as well as touch buttons for the back and menu controls. Naturally, the phone is driven primarily by its touchscreen, but there are a few physical controls dotted around the edge including the power button at the top, which also double up as a lock switch. As a result it feels very much like a traditional candybar handset when you hold it in your hand, which is a positive in our book. The handset is quite narrow by smartphone standards, measuring just 53mm wide. The gold colour is used on the battery cover as well as the two vertical edges, while the rest of the phone is finished in glossy black. We had the gold version in for review and while it definitely looked quite bling, it managed to not overstep the mark too much. The handset is available in four colours: Gold, Black, Pink and White. It’s also smaller than many of its rivals, so is it worth splashing your hard earned cash on? The Sony Ericsson Xperia ray is the company’s latest mid-range Android Smartphone, but it boasts some impressive specs including an 8.1 megapixel camera that allows you to shoot videos in high definition. On Windows, type \\RETROPIE into the computer folder.Naturally both your PC and Pi will need to be connected to the same network via Ethernet or Wifi in order to successfully transfer your files. Samba is a software suite that allows you to access file systems over the network. Once you've enabled SSH and connected to your chosen client, you can simply drop the files in the ~/RetroPie/roms/$CONSOLE folder, where $CONSOLE is the name of the target console, e.g. SFTP/SSH connection instructions are available on the SSH page. SFTP (Secure File Transfer Protocol) is a network protocol that allows you to securely transfer files over the internet or locally on the same network when both the PC and RetroPie system are connected to the same router via ethernet or wifi. The transferred games should now be visible within EmulationStation.Refresh the game listing in EmulationStation by pressing F4, or press Start on your controller > Quit > Restart EmulationStation.The ROMs have now been transferred from the USB to the RetroPie system's SD card If the USB stick has an activity light, wait for it to finish blinking, else wait (with many GBs of ROMs, wait several hours) Plug it back into the RetroPie system.Add the ROMs to the USB stick inside their respective folders within the retropie/roms/$CONSOLE folder, where $CONSOLE is the name of the target console, e.g.Remove the USB stick and plug it into the computer containing the ROMs.If the USB stick has an activity light, wait for it to finish blinking, else wait a few minutes Create a folder called retropie on the USB stick.Ensure that the USB stick is formatted to FAT32 or exFAT, and that the SD card has enough free space to hold all ROMs.There are three main methods of transferring ROMs: via USB stick, via SFTP, and via Windows (Samba) shares. That being said, in the search of your childhood - Google is your friend. There are many issues involving copyright laws regarding the usage of ROMs, so in order to preserve the integrity and longevity of the RetroPie project, the download locations of ROMs will not and cannot be added to the Wiki. In a RetroPie context, ROMs are digital copies of games which can be run on emulators (software that mimics your old gaming consoles). Universal Controller Calibration There’s also an SOS/Panic button that kids can push when they think they’re in danger, and parents will know where to find them, thanks to location tracking. You can block apps, create website and internet filters, and set up alerts for when certain people contact your child. The app works with Android or iOS operating systems, and you can link up to five devices to an account.Īs great as all of the time management features are on their own, the app does offer additional features. We particularly love how the app encourages kids to sign off early to save up and bank some of their minutes to use later as “fun time” (which parents also have full control over). Parents can use the app to do everything from setting screen time limits to creating internet time blocks to freezing their child’s phone remotely. If you’re looking for a parental control app to help you manage your child’s screen time, you can’t go wrong with FamilyTime. There are three options, ranging from five to 15 devices, starting at under $60 for a year's coverage. The app is free for one device, but you’ll need to purchase a plan if your child has multiple devices. Qustodio works on phones and tablets with Android or iOS operating systems, Windows computers, Mac computers, Chromebooks, and Kindles. Parents also get daily, weekly, and monthly activity reports as well as real-time alerts when their child may be in a dangerous situation. Qustodio can block inappropriate and potentially dangerous content and apps, send parents alerts when their child tries to access a blocked website, track device location, and monitor calls and SMS texts. Parents can limit their child’s screen time with this app and monitor how they spend time on their devices-including everything from browsing history to time spent on individual apps to YouTube views and more.Īnd that’s just scratching the surface of what this app can do. While there are a lot of great parental control apps on the market, Qustodio stands out because it allows parents to keep tabs on all of their kids’ devices no matter where they are. To help you narrow down your options, we researched over a dozen highly rated parental control apps and ranked our top choices below, based on their pricing, plans, and helpful features. The best parental control apps are affordable and bring peace of mind by offering features like location tracking, real-time alerts, call and text message monitoring, and even screen time management. Unlike a parental control router, which allows parents to control what websites kids can and can’t access when using their home wifi network, parental control apps let parents keep an eye on what their kids are doing on their devices wherever they’re at home, school, or anywhere else. Parental control apps allow parents to monitor and restrict what their children can do on their devices. Unfortunately, along with the educational, resourceful, and fun content online comes concerning and potentially dangerous apps, websites, and interactions. Between tablets, phones, and laptops, many kids have access to all corners of the internet starting at a very young age. TuneCore's reputation in the music industry In short, you come to the base for the distribution, but you stay for all the additional benefits, as TuneCore likes to say. Later in this test, we will detail all of TuneCore's services outside of distribution. In addition to offering the usual digital distribution services, TuneCore provides a number of tools that can benefit modern musicians such as personalized mastering, licensing of your covers, promotion on social media, feedback allowing you to hear the sincere opinion of your fans, and much more. Signing up and distributing through the TuneCore portal gives you access to over 150 music platforms around the world, from the most powerful in the industry like Spotify and Apple Music to some you probably haven't heard of before. What TuneCore doesĪlthough the company has diversified in recent years to offer more services, TuneCore's core business remains online music distribution. In 2019, the company announced that its artists had taken a symbolic milestone of reaching $ 1.5 billion in revenue, thanks to the growing popularity of genres such as heavy metal and J-pop. TuneCore's list of artists is impressive with 250K of them across the world. At the start of 2019, their artists totaled 200 billion plays and downloads, a figure representing an incredible 83% increase from their results the previous year. TuneCore ran into financial difficulties that we heard a lot about in 2012, but they have since rebounded in a spectacular way as reports show that the income brought by their artists is higher every year. That year we were talking about Tunecore in World News Tonight on the ABC channel, the Daily Mirror, and Pitchfork, because digital distribution was still in its infancy and because their first client was none other than Pixies frontman Frank Black. It is also established that the Nine Inch Nails went through TuneCore for the distribution of their album Ghosts I – IV on the Amazon digital platform a few years later. TuneCores' historyįounded in Brooklyn, TuneCore debuted in digital music distribution, publishing, and licensing in 2005. In this review, we'll tell you everything you need to know about TuneCore, from the history of the company to what it can do for independent musicians. TuneCore is a major player in digital music distribution, but that doesn't mean they are in a monopoly position, in a market with an exponential number of competitors who stand out by innovating and offering more affordable fees for clients. The company has been around for fifteen years and allows independent musicians who want to reach an audience to stream their music on platforms such as Spotify, Apple Music, Deezer, or TIDAL. A true pioneer in its field and with a solid reputation, TuneCore is a major company in the world of digital music distribution.
