All things computing, software engineering and physics related! Now also including retirement stuff.

Start of semi-retirement
Thursday, 30 June 2022
End of consulting projects!
The last couple of years have been frantic. I was supposed to be retired but ended up on a couple of projects that ate up the time.
HOWEVER - as of yesterday.....
I have taken the decision to down tools on consultancy work and focus on stuff I want to do. That includes travel as well as finishing off the frog and bridge products we have built within the Advisory business.
Feels like I've retired - still 'working' but not getting paid for any of this - does that constitute retirement?
Anyway I need to run through what I can remember of the past year to try and not have a gap in the blog records.
Things that happened in 2021 and up to July in 2022 that I can remember - in bullet form,
- Presentation of bridge monitoring and satellites at Manseds conference - first I'd done in quite a while.
- Many trips to the 'Static' in Wales - excellent working breaks.
- Roxy (our motorhome) trip with Amanda around Scotland - fantastic!
- 1st and 2nd Glasbury bridge recordings taken with SAIN
- Anniversary in LLandrindod Wells
- Start work on Autonomous Minesweeper project for Thales.
- Trip to Plymouth to see 'the boat'
- Trip to Madrid with Richard to visit FOSSA Syatems and update on SAIN dev.
- Christmas in the Static
- Trip to Maui - WOW always great. Lahaina flat and worked through analysis of SAIN data with Stuart.
- Trips to Bristol, Templecombe on Thales job
- Trip to Crete on historical tour.
- HS1 'wall' recordings with SAIN
- 3rd Glasbury bridge recording
- Salisbury and Bristol again to finish Thales job.
- ENDED CONSULTANCY PROJECTS FOR NETWORK RAIL AND THALES IN JUNE

2020 - Year of the lockdown
2020 - A strange year all in all - but major progress was made!
The potted history;
- Project work rolled in throughout the year which was very good for business finances.
- Big ticket item is that we finally delivered the 25 Manchester Metrolink Safety Cases for Thales - after 5 years!
- We took up residence in Sensor City offices in Liverpool. Then promptly got moved out to Liverpool Science Park while the SC offices were being 'expanded'. We will see if we ever move back?
- We built our rail infrastructure simulator CLAMP Critical Location Acoustic Modification Platform and took many thousands of readings for various void and bridge configurations.
- We were planning of running some real field tests with SAIN but lockdown put a stop to that. So we ended up doing runs on CLAMP.
- We secured a trial on road bridges in Powys which hopefully we will carry out this year - once we are out of the third lockdown period!
- Ten SAIN units are now on delivery from Fossa for this project.
- We are also firming up our bridge signature analysis and hope to be presenting the results in Mallorca at the Civil Comp conference in 2021.

2018 - where did it all go - just realised I didn't do one of these
Busy, busy, busy.....the journey continues.
Name of project
|
Uncertainties at start
|
Issues arising during project
|
Further work
|
Ongoing/Ended
|
CROAC – app to analyse Costa Rican frog
calls.
|
Could we develop an analysis package to
run on mobile phone for identifying calls in the wild.
|
Difficulties with running complex
analysis fast enough on mobile devices.
Complexity of the background noise to
the calls. Resulting in false calls.
|
Algorithm needs refining to help reduce
false calls.
|
Ongoing
|
Rail infrastructure health monitoring.
|
Could the health of railway
infrastructure (points, bridges, tunnels etc) be monitored through their
changing sounds.
|
Difficulty getting access to real
railway infrastructure. So we used a model railway to prove the concepts and
think through the sensors required.
Preliminary analysis showed simplest
analysis would be to focus on bridges.
|
Need to develop sensor to a level where
it can be left for a period of time in the field.
Need to prove we can identify signals
for real railway bridges.
|
Ongoing
|
PACE – air-conditioning control system.
|
Could a new air-conditioning approach
be controlled using the new LoRA radio communication protocol and a simple
control device.
|
Control of the peltier cooler was
non-trivial requiring significant hardware modifications.
LoRA communication setup proved less
effective that originally anticipated.
|
May look to use more standard
communication methods.
|
Ended – proved LoRA is not right for this
system.
|
Wheel slip analysis
|
Could a big-data approach be used to
analyse rail wheel slip occurrences.
|
Access to appropriate data was
difficult to obtain.
Data was provided by Siemens in the end
but then we ended up with too much data. Effort then had to be expended
refining this data.
|
Initial analysis has demonstrated the
technique. Larger data sets are now needed to refine the algorithms.
|
Ongoing
|
FOSSA – satellite swarm communications.
Effectively he ‘glue’ to communicating and transmitting data from remote
monitoring devices using cheap satellite systems.
|
Could a cube-sat be developed to use
the new LoRA communication protocol. Built and launched at low cost.
|
Difficulties encountered applying the
LoRA protocol to the satellite communication time window.
Power consumption on the satellite
required special design of solar cells.
|
The cube sat now needs final build then
tested and commissioned for flight
|
Ongoing – launch planned for Sept 2019
