Ok, so who do I have to bribe on ACGAS to put Siegfried in this corduroy suit, so I can be the laziest cosplayer ever and just grab what's in my closet. 😅

(You all know I will be deranged about something, nonetheless. Am thinking about needle felting Volonel, Siegfried's pet rat.)

Suit by Cathcart Heritage (from where I'll order the full 3-piece tweed suit), will post more about the fit soon, as I'm wearing this to be twee at a thing in 2 weeks. Shirt is from Darcy Clothing. Vest and tie are not vintage, but work fine for this look. Pipe is from my stash back when I used to indulge.

Resonance Analysis: Tips and Techniques for Cable Line Optimization

In the present industrial stage, the inspection and performance of wire systems, particularly those which are used as cables for the control and instrumentation applications is critical for the safety and proper functioning. The challenge of aging of wire systems is growing across oil & gas, transportation, and some defense sectors. The nuclear industry is an example of the extended lifetime that cables are required to uphold, which is often offered above 40 years. Nevertheless, the challenges of harsh environmental circumstances and correcting by-pass impedance are still to be addressed leading to the development of the more sophisticated techniques such as Cable Line Impedance Resonance Analysis (CLIRA).

Understanding CLIRA: A Comprehensive Measure Proposal

Cable Line Impedance Resonance Analysis (CLIRA), also linguistically the same with Line Resonance Analysis (LIRA), is now being used as a method to monitor cable status. The CLIRA (a short- for “Cable Linear Interaction and Response Analysis”) tool employs 

transmission line theory to carry out a cable behaviour study under diverse conditions. First, CLIRA examines the complex cable impedance spectrum, allowing to recognize such insulation imperfections like thermal degradation and mechanical damage.

Key Principles of CLIRA:

Transmission Line Theory: The transmission line theory from the CLIRA places emphasis on how the action of the cable depends on the sizes of the signal's wavelength and the cable's length.

Characterization Parameters: In its performance CLIRA uses the skin effect resistance (R), the sheathing inductance (L), the cable capacitance (C) and insulation conductivity (G) as the parameters to evaluate the cable behaviour.

Impedance Spectrum Estimation: CLIRA software utilizes the institution of their own algorithms which determine the comprehensive layout of the cables and then estimates both local and global degradation.

Tips for Effective Cable Line Optimization:

Baseline Measurements: First of all, you have to define your initial scope of the measurements, for it will allow to understand the state of the system after the tests and analysis.

Damage Detection: Engage the use of CLIRA together with other techniques, including TDR, for reliably detecting the impact. Despite the fact that TDR is an extremely accurate method to determine the exact wiring defects, CLIRA provides a picture of a cable’s overall health.

Custom Algorithms: Features such as custom algorithms within CLIRA for precise parameter determination like phase velocity, not dependent on cable length or load attributes made possible.

Continuous Monitoring: CLIRA should fit in a multiparametric monitoring system and augment material screening for the continuous evaluation of cable health, with special attention given to nuclear power plants operating environment.

Ultra-sonic and other Non-Destructive Testing of cables that are tested without the need of energising the cables with high voltages. More likely to be used in a ‘high risk’ scenario than other methods

LIRA has been made as small as to be placed on electrical cables up to few hundred kilometres long and is gradually evolving as a condition monitoring or fault locating tool in the distances (like, for instance, a submarine cable that connects an off-shore platform to the grid).

Through IRLA, it is possible to test for and to find the various types of flaws and faults in insulation such as temperature and radiation damage, moisture intrusion fluid as well as mechanical impact being a fair sample.

LIRA makes use insulation conditions to impose a relationship between which and capacitance and therefore calculates the impedance spectrum (amplitude and phase) as the applied signal increases over the wide frequency band.

The capacitance of a cable changes as a function of changes in the cables permittivity and changes in the cable’s radius, as shown below:The capacitance of a cable changes as a function of changes in the cables permittivity and changes in the cable’s radius, as shown below:

R = series resistance L = series inductance G = parallel conductance C = parallel capacitance

The changes in the permittivity and radius determined the neighboring impedance. Impedance mismatches show up exactly where immunancies are the most - specifically, it is when the cable ends. LIRA will generate standing wave patterns on short open circuits by comparing them to existing ones and promptly informing the system operators of slow impedance value changes.

Features and Benefits

LIRA can be applied to cables hundreds of kilometers long, in contrast to VLF associated with the use of the latter being restricted to the cables with a length of maybe 10km.

Useful for cable testing where hazard of applying energy to fully working voltage range exists.

With this technology you may apply fingerprinting used as your initial tool that allows you quickly to distinguish between the good cable and the bad one. This strategy showed the best outcomes.

Precise evolution of the impedance value will reliably demonstrate the presence of the anomaly.

Faults are isolated into a section located within 0.3% of the cable system.

precisely pinpoint sources of joints that are typically impossible to recognise.

LIRA can detect the following phenomena:

Global insulation degradation

High Temperature damage

Moisture ingress

Radiation damage

Mechanical effects/defects

*Note: When the highest sensitivity is the goal, expect a slight loss of signal at the multiple impedence changes so it is recommended to test from both ends. However, this does not need to be done.

Maximizing Sensitivity and Efficiency:

In order to achieve most sensitivity and be able to test signal gain at each location of impedance changes, it is highly recommended to conduct LIRA testing from both ends of the cable. However, it is not a formal requirement yet which gives priority to achievement of detection accuracy and efficiency, particularly, in sophisticated cable networks.

Conclusion:

We conclude that the Best Cable Line Impedance Resonance Analysis technique, is a very safe, reliable, and highly effective method for diagnosing line deterioration and may be performing necessary maintenance during the process of a line performance enhancement. It is the most advanced non-destructive technology known for comprehensive fault detection, accurate localization and being environmentally non-invasive that is the best solution for ensuring safety and reliability in modern industrial technology.

Oh, I love Summer so much, I just had to make some more CN art for it. 🧡

It’s such a beautiful day today and everyone is at the beach to have some fun. (And so was I earlier today, lol.)

This piece and a follow-up night one (coming soon) were inspired by the 2009 “CN Summer in Italy” bumpers.

Summer is short, y’all, enjoy it while it’s here, before the cold kicks in and the winter depression hits. Have a fun one out there and stay safe!

P.S. (I didn’t know there was a tag limit, whoops. Guess that’s what happens when I try to put as many characters in one image as I can.)

V quick and unfinished sketch, but look at the improvement!! (Now vs april 2023)

Another thread by Senator Ben Ray Luján here.

A book on the subject (haven't read it myself):

One of the sources in another one of Alisa's furiously impassioned twitter threads have been debunked, so I didn't include that. But she claims that her own family was caught in the fallout zone when her mother was a baby, which eventually led to her and large numbers of her community developing cancer. It's human for that kind of grief to be caught up in inaccuracies. People are already being ghastly and racist to Hispanos and Indigenous people criticizing the hype for the movie. They're not attacking Oppenheimer for being Jewish, they're criticising the erasure of the human cost of these bombs and the continued valorisation of the U.S military's actions in World War II as some kind of moral saviourism.

While Oppenheimer himself believed that the nuclear bombings of Hiroshima and Nagasaki were morally justified (they had planned to drop them on Germany except they surrendered before they could), he also felt had blood on his hands and regretted his role as the "Father of the Atomic Bomb". He spent the rest of his career vehemently opposing further development of thermonuclear weapons and the hydrogen bomb accurately predicting the concept of mutually assured destruction. This eventually made him a victim of Senator McCarthy's Red Scare and his clearance was revoked. I haven't seen the movie (Christopher Nolan is the kind of casual white racist I avoid on principle) but people who have seen it say that it doesn't glorify nuclear weapons and depicts the man himself with the complex moral nuance that seems to be accurately reflective of his real life.

The backlash to Indigenous and Hispanos people's criticisms and to people pointing out that Hiroshima and Nagasaki were genocides is also frustrating because...both world wars were a clash of genocidal empires. The reason they were world wars is because the countries colonized by Japan, China, the European powers and the US were all dragged into it, whether they wanted to or not. Jews were one of the many colonized peoples that suffered in that time, who were left to die by everyone until they could be used to frame the Allied powers as moral saviours, establishing a revisionist nostalgia for heroism that powers the US military industrial complex to this day.

As early as May 1942, and again in June, the BBC reported the mass murder of Polish Jews by the Nazis. Although both US President, Franklin Roosevelt, and British Prime Minister, Winston Churchill, warned the Germans that they would be held to account after the war, privately they agreed to prioritise and to turn their attention and efforts to winning the war. Therefore, all pleas to the Allies to destroy the death camp at Auschwitz-Birkenau were ignored. The Allies argued that not only would such an operation shift the focus away from winning the war, but it could provoke even worse treatment of the Jews. In June 1944 the Americans had aerial photographs of the Auschwitz complex. The Allies bombed a nearby factory in August, but the gas chambers, crematoria and train tracks used to transport Jewish civilians to their deaths were not targeted.

Uncritical consumption of World War II media is the reinforcement of imperialist propaganda, more so when one group of colonized people is used to silence other colonized peoples. Pitting white Jewry against BIPOC is to do the work of white supremacy for imperialist colonizers, and victimizes Jews of colour twice over.

Edit: friends, there's been some doubt cast on the veracity of Alisa's claims. The human cost to the Hispanos population caught downwind of the nuclear tests is very real, as was land seizure without adequate compensation. However, there's no record I can yet find about Los Alamos killing livestock and Hispanos being forced to work for Los Alamos without PPE. There is a separate issue about human testing in the development of said PPE that's not covered here. I'm turning off reblogs until I can find out more. Meanwhile, here's another more legitimate article you can boost instead:

Okay listen. When I decided to give squid Jean (squean) bite marks/scars last year I was just making it make sense that he lived with a pod of orcas who thought it was super fun to scare him and threaten him, I didn’t know tsc would come out and make that detail somehow 100x worse

Someone get this kid to Whalemack and Abby stat :( thank you Renee
