Highlights of last month's discussion topics (previous)
We browsed the last month's 40 messages, which were really not many. Also most of it was advertising and web page announcements. With the NDTnet Forum we don't want to make any competition, but there we had 80 messages and the question is allowed - Is the NDTnet Forum more attractive then the Newsgroup?

Highlights of last month's discussion topics (previous) We browsed the last month's about 75 messages. As usually advertising and web page announcements was a big part of it. I will try to cover the main topics here (in my opinion), in this review, as well some major keywords are listed in the right hand frame. You can brows topics of your choice by clicking the "Show all March Posts" button on this page.

Highlights of last month's discussion topics By Rolf Diederichs With 135 posts a very active discussion took place during August 1999, although many messages have been posted multiple. The topic "ASNT" and "Technology from Russia" was a big part of it. Joe Buckley covered on a web page a part of the ASNT story, with comments and downloads in PDF format of some newsgroup attachments. For more information you may search the Newsgroup Archive. |
Highlights of last month's discussion topics By Rolf Diederichs After only 40 messages during June, 100 messages were posted during July. Unfortunately banal, repetitious advertising was a big part of it. (e.g. Tracor/Spectrace XRF5000E X-ray Florescence Spectrometer $8900. This started a debate about appropriate posts. Over the last 3 years, I remember seeing this same argument a number of times. Here Jay L. Fisher, from SwRI, tries to find a consensus. 1999/07/19. In my opinion the newsgroup is bothered more by the NDT trade companies than from real spam. In Site for Commercial Advertisement William E. Blum recommended the use of NDTnet's Classified Ads Board. Anyway, we did have some good topics - they're listed in the right hand frame. Some of the most interesting topics are listed below with a link to the full message. Remember, to see all replies, you cannot rely on the "View Thread" link at the Deja Database. You'll need to browse the subject line for the entire month to find all related replies. Also there are posts from job seekers and employers. NDT manufacturers will find some posts which seem to be serious inquiries. Inspection of Parts in Inconel 1999/07/31]. Aerospace parts in AMS5662E Inconel 718 and 625, which contain 55% and 61% nickel respectively. The material will be heat treated/precipitation hardened to achieve high strength properties.

Highlights of last month's discussion topics By Rolf Diederichs A traffic of only 40 messages during June shows that the Newsgroup started already a summer break.

Highlights of last month's discussion topics. By Rolf Diederichs Before we start our review I would like to mention some new features of the Deja Newsgroup Database which you may like to check out. But take care: There is always a mix-up of the thread of messages, this may happen since some of the posts are forwarded by the SWRI mailing list. That means you cannot rely on "View Thread" or "Track Thread" functions. You need to browse the subject line to find the corresponding topic posted as "Re: Subject" at another date and perhaps another thread starts again. The newsgroup had 64 messages. As usual I will try to cover the main topics here in this review, also some major keywords are listed in the right hand frame. You can browse topics of your choice by clicking the "Show all May Posts" button on this page. The message "GPR FOR BRIDGE ASSESSMENT" 1999/05/14 shows us to clear not to get to much use of abbreviations like GRP (Ground Penetrating Radar); a reader asked "What's GPR?". I hope that UT is acceptable. For the question "Plating Thickness Question" 1999/05/20 you can find a detailed answer by Tom Nelligan from Panametrics Inc. Not only in our Forum is Tom very active in helping to answer questions. But not every question is followed up: "3d elastic constants" 1999/05/21 or "UT/Thermography of duplex ??" 1999/05/25. Even the message "8 Channel multiplexer" 1999/05/22 received no reply. Maybe it would be better to write "Need a 8 Channel multiplexer to bring up some vendors on the plan. "matest 99"1999/05/21. Due to the activities of NATO forces against Yugoslavia the MATEST’99 Symposium - Advanced NDT techniques, has changed its venue to the Dubrovnik region, which is safer. "Wall Thickness Measurement with Pulse Thermography" 1999/05/26. We invited Volker Carl to write about his newly developed method on NDTnet. "2D & 3D Tomography" 1999/05/27 . This message announced a Web Site of Gamma Ray Computerized Tomography for 2D and 3D NDT inspection. The site has some nice images (including animation) at http://www.icpe.ro/lab/comp-ndt/ We added this server to our Virtual Library (NDTnet Internet crawler).

By Rolf Diederichs Highlights of last month's discussion topics
Last month's 88 (65) newsgroup messages indicated an increase in usage,
and our NDT.net Forum received a
very busy 75 messages during January - The New Year starts with time for
discussions or for gathering information! In the last review I pointed out that the NDT Mailing List wasn't forwarding all Newsgroup posts correctly . Most of the people assumed that all the posts were reaching them via the list server. The List owner (SwRI) hopes that they can get this gateway working smoothly again soon [Ref]. It is possible to access the Newsgroup directly, but it could be easier. If it doesn't get fixed soon we will all need to start looking at the newsgroup itself. Eddy Current Testing was obviously the topic of the month, with 12 messages , however, most posts like 'looking for vendors topics' received a lot of replies. Only the post RFEC describing an inspection problem and asking for technical advice is still waiting for an answer - Who can help? The message Re: Seeking vendors for leak detection in underground pipes listed search results on Infrared thermography of the SPIE Database. That was a good pointer for those who did not know about the SPIE Web Site. For more information you may search the Newsgroup Archive. |
By Rolf Diederichs Highlights of last month's discussion topics previous months Last month's 65 newsgroup messages during the holiday season broke no traffic records, nevertheless a few issues were interesting. First Newsgroup mailing list subscribers may have noticed some technical difficulties recently. The owner (SwRI) tried to fix it and checked it with the test message "Mailing List Test Please Ignore" 1998/12/03. That message made it, but most of them are still not getting through. We hope that (SwRI) can resolve this problem soon, in the meantime, over 300 subscribers must use other options, none of which offer the same convenience and automation of the mailing list. Non-destructive testing Non-destructive testing 1998/12/02, with this message a Russian Institute gathered information about technological performances of non-destructive testing tools for inspections of plants of petroleum and gas branches (oil pipeline or main gas pipeline with a diameter 370-1440 mm, steel tanks etc.) - prices were requested! One message pointed to a Web Site of France NDT resources (in French). Although the site is neither comprehensive nor available in any language other than French, it is still a good start to the process of building awareness of French NDT on the Internet. Problem with ultrasonic wall thickness gauging of wax injected around a ceramic 1998/12/05, so far, no one has offered this poster any solutions. NDT in process monitoring is indeed a challenge, and we hear a lot of discussion of this topic. For more information you may search the Newsgroup Archive. |
