A sign of normality returning

I am in the midst of marking examination scripts.  I have about two weeks to award a maximum of about 26,000 marks which is a huge number of decisions to make in a relatively short time [see ‘Depressed by exams‘ on January 31st 2018].  Although the pile of examination scripts is tall and the task can feel overwhelming, it represents a return to normality following the pandemic when we conducted on-line, open-book examinations [see ‘Limited bandwidth’ on June 2nd, 2021].  We have been teaching 100% on-campus for the whole semester and all of our examinations have returned to their pre-pandemic format, i.e., the majority have been in-person, closed-book and invigilated.  I have enjoyed teaching thermodynamics in a huge lecture-theatre filled with students and it is relief that I do not have to set examination questions whose answers cannot be found using a search engine or solved using a programme.  Anyway I need to pick up my red pen and return to my marking so only a brief post this week.

It is hard to remain positive

Frequent readers of this blog will have noticed that I am regular reader of the FT Weekend pages.  I particularly like the ‘Life & Arts’ section for its balance of opinion and reviews.  However, one weekend last month I was depressed by two articles I read in quick succession.  Shannon Vallor described life as an ageing roller coaster with failed brakes and ‘accelerating climate change, a deadly pandemic and unravelling global supply chains’.  While on the facing page Nilanjana Roy wrote that the ‘past few decades have brought humankind and most other species on Earth to the brink of destruction’.  I was depressed because I agree with their analysis and our leaders seem either unaware of the impending crash of the roller coaster or unable to construct a global strategy to avert the looming destruction.  However, spiralling into negativity does not help because negativity tends to promote fight-or-flight survival mechanisms that can lead to narrow-mindedness, a lack of creativity and limiting one’s options to the tried and tested actions which are unlikely to avert destruction.  Whereas a positive outlook broadens your repertoire of options and builds physical, social and psychological resources.  Positive psychological capital, associated with hope, efficacy, resilience and optimism, leads to higher positive outcomes including commitment, successful outcomes, satisfaction and well-being.  In the face of apparently insurmountable challenges it is difficult to remain positive whether you are leading a small team, a department, an organisation or a country; nevertheless it is important to remain positive because research shows that the ‘happier and smarter’ approach works better than the ‘sadder but wiser’ style of leadership.  Of course, extreme positivity is usually delusional or irresponsible and can lead to complacency; so, you need to dodge that too.

Too much of a good thing?

I wrote a couple of weeks ago about ‘Our last DIMES’ meetings (on September 22nd, 2021).  They were hybrid meetings with about half the participants attending in person and the remainder on-line.  When the pandemic started we had to master the skill of conducting discussions via our laptops while sitting on our own.  Now, we are learning how to include everyone in a discussion when only half of the participants are in the physical room.  One of our first steps was to re-equip our meeting rooms with higher quality video conferencing facilities so that we can see and hear one another more clearly.  Unfortunately, our new equipment revealed the poor quality of the video clips we have produced during the DIMES project.  Nevertheless, if you have never been present during a wing-bend test or a fatigue test on a large composite panel then you might find these clips interesting (see also the video of ‘Noisy progressive failure of a composite panel’ on June 30th 2021).  We also produced an introductory video for the DIMES project which was to be first in a series of video shorts but the pandemic intervened and we have never been in the same place as our camera crew so we have not made anymore.  Maybe that’s a good thing because 500 hours of video are uploaded every minute to YouTube so you will not have time to watch our DIMES videos 😉.

Our last DIMES

Photograph of wing test in AWICThirty-three months ago (see ‘Finding DIMES‘ on February 6th, 2019) we set off at a gallop ‘to develop and demonstrate an automated measurement system that integrates a range of measurement approaches to enable damage and cracks to be detected and monitored as they originate at multi-material interfaces in an aircraft assembly’. The quotation is taken directly from the aim of the DIMES project which was originally planned and funded as a two-year research programme. Our research, in particular the demonstration element, has been slowed down by the pandemic and we resorted to two no-cost extensions, initially for three months and then for six months to achieve the project aim.   Two weeks ago, we held our final review meeting, and this week we will present our latest results in the third of a series of annual workshops hosted by Airbus, the project’s topic manager.   The DIMES system combines visual and infrared cameras with resistance strain gauges and fibre Bragg gratings to detect 1 mm cracks in metals and damage indications in composites that are only 6 mm in diameter.  We had a concept design by April 2019 (see ‘Joining the dots‘ on July 10th, 2019) and a detailed design by August 2019.  Airbus supplied us with a section of A320 wing, and we built a test-bench at Empa in Zurich in which we installed our prototype measurement system in the last quarter of 2019 (see ‘When seeing nothing is a success‘ on December 11th, 2019).  Then, the pandemic intervened and we did not finish testing until May 2021 by which time, we had also evaluated it for monitoring damage in composite A350 fuselage panels (see ‘Noisy progressive failure of a composite panel‘ on June 30th, 2021).  In parallel, we have installed our ‘DIMES system’ in ground tests on an aircraft wing at Airbus in Filton (see image) and, using a remote installation, in a cockpit at Airbus in Toulouse (see ‘Most valued player performs remote installation‘ on December 2nd, 2020), as well as an aircraft at NRC Aerospace in Ottawa (see ‘An upside to lockdown‘ on April 14th 2021).   Our innovative technology allows condition-led monitoring based on automated damage detection and enables ground tests on aircraft structures to be run 24/7 saving about 3 months on each year-long test.
