Mercury vapor lamps are so-called gas discharge lamps, which were already used in the first half of the 20th century. UV mercury vapor lamps were initially used in the non-destructive material testing, they were the basis of the NDT. Mercury vapor lamps – the previous standard If necessary, it can also climb and reach places and areas that could never be tested with a stationary UV lamp. Because if the tightness of pipes or the like has to be checked, the NDT user must be equipped with a light, handy UV flashlight. Mobile UV-LED flashlights are particularly suitable in industry for testing industrial plants. This allows the right UV flashlight to be supplied for every application for optimal results. UV flashlights are small and handy and are offered by SECU-CHEK in a wide variety of model variants. UV flashlight – mobile UV lights in many variations This allows for a completely new, improved and, above all, faster visual inspection. As a result, the UV LED can be switched on and off at any time and a so-called crossfade film can also be passed through with the patented automatically dimmable white light. Industrial users of UV-LED lamps benefit from the direct availability of the UV light source immediately after switching on. Furthermore, UV LEDs are characterized by a very long service life and a significantly lower sensitivity to impacts etc. In addition to the higher energy efficiency, which has a significantly lower energy consumption for UV LEDs, there is also a lower heat generation in the UV LEDs. In addition to the visual aspect, UV LED lamps also have some economical advantages. In this case, certain fluorenic dyes are often used to further increase the visual capacity. The long-wave black light of the UV LED provides improved visual display when inspecting safety-critical components. The use of UV LED in non-destructive material testing (NDT) offers some advantages over the previously commonly used mercury vapor lamps. UV LEDs are light-emitting diodes (LED) and work with ultraviolet radiation. UV LED in industrial use – these are the advantages SECU-CHEK, a manufacturer of special UV LED lamps, has revolutionised the possibilities of testing materials and provides a higher level of safety and better display during testing with various functions such as the dimmable white light for UV lamps. Thus, UV lamps are of enormous importance, as they prevent possible accidents and disasters. UV lamps are used to test the chassis of aircraft, as well as glass panes and paint coatings, for cracks and jumps. The NDT and thus UV-LED lamps have a great influence on the daily life of many people, without many people even being aware of this. This is called the Non-Destructive Testing (NDT). In the aviation industry, for example, tests are carried out with UV lamps for the quality control of engines and technical inspection of components in order to detect the smallest hair cracks and other defects. Especially in industry, UV lamps are now indispensable. Buy UV-LED lamp directly from the manufacturerĪ UV lamp or UV-LED lamp is used in a wide range of applications.

You cannot start traceSM and expect to see SIP packets that were sent prior to launching the tool. It’s important to know that traceSM is a real-time capture tool. Switch between SIP calls and display mode Switch between displaying RTP simulation or not Switch between displaying Names or IPs in the column headers Write the displayed (filtered) packets to a new file The SIP URI is highlighted in red, the SIP fields in blue and the content (e.g: SDP, xml) in green.ĭisplay the Filter window to view/change filters Move between different columns (IPs) when they don’t fit in the screenĭisplay the SIP/SM details. If the cursor is in the last packet while capturing packets, the screen will update with new arriving packets Or scroll a large SIP packet when displaying the details Since you are in a Telnet session, forget about using your mouse. It’s traceSM and never tracesm or Tracesm. TraceSM should be accessible through the default path, but in case you ever need to find it, look under /opt/Avaya/contrib/bin. However, Avaya advises against running multiple instance of traceSM in a production environment as it may cause performance problems. To invoke multiple instances, it must be run with the -m option. Personally, I use the TuTTy program, but you can accomplish the same thing with vanilla PuTTY.īy default, only one traceSM can be running on a Session Manager at any given time. To run traceSM you need to Telnet into an active Session Manager. Second, traceSM allows you to see Avaya specific data such as Personal Profile Manager (PPM) messages and Session Manager call flows. First off, it allows you to view SIP messages even if they have been encrypted with TLS. While not as powerful or versatile as wireshark, traceSM is absolutely essential when it comes to working with Avaya SIP. TraceSM is an interactive perl script that allows an administrator to capture, view, and save call processing activity on a Session Manager. Understanding Avaya’s Personal Profile Manager (PPM) The Steps Involved in Booting an Avaya SIP Telephone These two articles may help you better understand Avaya SIP and subsequently, traceSM. Therefore, I am documenting what I know in the hope that the next person who endeavors a search will find this blog article and have something to work with. I have also asked people who work with traceSM on a regular basis if they’ve found anything useful and I always come up empty. I would love to be proved inept in my efforts, but I’ve searched through every Session Manager document I can find. As hard as I’ve tried, I have yet to find a halfway decent manual that explains how to use what is perhaps the most important Session Manager debugging tool. Case in point is the Avaya utility, traceSM. Check the rules and regulations of the site before you book. Sitting around a firepit in the evening is a lovely part of camping, but not all sites permit people to have fires (often, for good reason, if pitches are close to one another). Plenty of commercial places pack lots of people into fairly featureless fields, but if you look around, you can usually find somewhere that offers at least the illusion of a wild experience, with trees and bushes creating a bit of privacy around your pitch. I still find scoping out an adventure one of the most exciting elements of the experience.ĭecide where you want to go and do some research into the nearby camping facilities. But, for your first outing under the stars, it’s well worth spending some time and making a proper plan. Once you’ve cracked it and have all the kit you need stashed somewhere easily accessible, camping is beautifully simple, and the ability to spontaneously decide to head off for the weekend to the coast or explore a wild area is a massive part of the appeal. Air tents are more of an investment, but they are really easy to assemble. (In fact, large tents get much colder during the night, so if you’re camping outside of summer, bear that in mind.) Tunnel tents are easy to put up, reasonably cheap to buy and can be found in a wide selection of sizes. Tip: Wet weather play – Take some playing cards and plenty of other games, just in case the weather turns against you.īigger isn’t necessarily better, though, and you don’t need a palatial tent that takes up half your car and requires hours of sweating and swearing to pitch in order to have a good time. You obviously need enough room for everyone to sleep comfortably, and if you’re car camping, then having a vestibule where you can eat and hang out if it rains is really important. There are myriad designs and all sorts of sizes out there – but for your first camping experience, keeping things simple is the secret to success. The single most important thing you need is, of course, a good tent (the best tent, even) that can house you and the crew. Here are a few gable roof photos, so you can see what they look like. Wikipedia describes a gable as “the triangular portion of a wall between edges of intersecting roof pitches.”Ī gable roof includes two sloping sides and at least one gable. The dictionary defines a gable as “the part of the wall that encloses the end of a pitched roof.” (Also known as a clipped-gable or jerkin head roof) HALF-HIP ROOF – this is an add-on to a gable roof, where the end of the gable includes a small hip roof section that slopes toward the ridge.DUTCH GABLE ROOF – a variation of the hip roof, that includes a small gable section on the upper portion of the roof.TENTED ROOF – a multi-sided (polygonal) hip roof with steeply pitched slopes that rise to a peak, similar to what you’d see on a church steeple.MANSARD ROOF – a type of hip roof, where each side includes two different sloping angles with the lower angle much steeper than the upper angle.PAVILION ROOF – a hip roof on a square structure, where all sides join to form a single peak.Here are a few hip roof pictures so you can see what they look like. Hip roofs are generally more costly to build than a gable roof. The “hip” refers to the external angle formed where two adjacent sides meet.ĭue to complexity of design and construction requirements. Or with the ends sloped inward toward a ridge formed by the adjacent sides (if the structure is rectangular). It is sloped on all sides, with the slopes meeting in a peak (if the structure is square). During the late 1800s, one of the most popular house styles was the gable front house, according to Artisans of the Valley. These surfaces meet along a central ridge at the top of a house, and in doing so create two gable ends, or triangular wall sections. What is a Hip Roof?Ī hip roof has no vertical ends. A gable roof is a type of roof structure that consists of two large, sloping surfaces. Others use a combination of both roof types to create unique roof designs. With lots of angles, valleys, varying pitches, dormers, etc.Īnd while many roofs are strictly hip roofs… Most residential roofs are sloped, so water runs down the slope into gutters or off the eaves. Check out our 51-point inspection guide for roof hail damage. The purpose of your home’s roof is to protect the entire structure (and you) from weather. A hip roof is a roof where all four sides of the roof slope downwards from the peak.

Khan Academy founder Salman Khan, a former hedge fund analyst, grew YouTube video tutoring sessions for his cousin in 2006 into what Forbes ' Michael Noer called "the largest school in the world"-a non-profit with ten million students and a reported $7 million annual operating budget (2012). In his 2010 TED Talk on crowd-accelerated innovation, TED curator Chris Anderson preliminarily noted that human brains are "uniquely wired" to decode high-bandwidth video, and that unlike written text, face-to-face communication of the type that online videos convey has been "fine-tuned by millions of years of evolution." Referring to several YouTube contributors, Anderson asserted that "what Gutenberg did for writing, online video can now do for face-to-face communication," that it's not far-fetched to say that online video will dramatically accelerate scientific advance, and that video contributors may be about to launch "the biggest learning cycle in human history." Salman Khan speaks at TED 2011 about the Khan Academy, which began on YouTube and became what was called "the largest school in the world". Conversely, individuals have partnered with advertisers to grow their own audiences, the "Partner Program" enabling individual content creators to monetize videos and even earn livelihoods directly from posting content, with top earners exceeding $30-50 million per year.Įffects on culture Education and proliferation of knowledge Celebrities and large companies, especially major music labels, have used YouTube as a focused advertising tool for targeted mass marketing and audience growth by placing banner ads and by contracting with video producers for embedded-product marketing. YouTube streaming data (video views) has been used to gauge consumer opinion for marketing decisions. Concurrently, the website has been criticized for inadequately policing against false or misleading political content. However, its recommendation algorithm has been shown to recommend extremist content, especially far-right and conspiracy propaganda, leading to claims that YouTube has been used as a tool for political radicalization. YouTube has affected conventional politics, becoming even more important than direct mail in political campaigning, with politicians and governments using the website to directly engage citizens and promote policies. YouTube has promoted democracy through free expression of individual political views, for example enabling Arab Spring protest videos to transcend national boundaries, causing certain regimes to censor or ban the website. Certain independent or alternative news organizations have established YouTube channels that reach a wider audience than traditional broadcast television. YouTube has become an important "visual journalism" platform, both for conventionally produced content from established news organizations and for citizen eyewitness contributions. Further, the website's recommendation algorithm has been found to recommend harmful content to children, and has promoted dangerous practices such as the Tide Pod Challenge. However, other videos have included potentially harmful content, such as those triggering self-harm, or inspiring additional bullying or suicides. Also, some YouTube videos increase awareness of social issues (such as bullying, suicide and LGBT issues), allow broadened social contact (especially important for the elderly or mobility-impaired), and overcome stereotypes of minorities and minority viewpoints. YouTube has facilitated engagement between institutions and individuals, such as between universities and prospective students, and between businesses and employees. Worldwide video access has spurred innovation by enabling geographically distributed individuals to build upon each other's work, to collaborate, or to crowdsource. adults, Ĭonstituting one of the world's most popular search engines, YouTube enables inexpensive distribution of educational content, including course material from educational institutions and "how to" videos from individuals. It the world's largest video hosting website and second most visited website both by Alexa Internet and Similarweb, and used by 81% of U.S. The American online video sharing and social media platform YouTube has had social impact in many fields, with some individual videos of the site having directly shaped world events. "An Anthropological Introduction to YouTube" To people we love, to people we want to love, or people we don't even know. The most public place in the world, from the privacy from our own homes: YouTube has been used for many things: a political soapbox, a comedian's stage, a religious pulpit, a teacher's podium, or just a way to reach out to the next door neighbor or across the world.
