Dissertation Blues

[windym]

In the middle of a tricky dissertation bored and stressed not a good combo. Figured I would take a break and try out the new tyres on a longer run.

So had a cruise round the villages of Essex, all country lanes fairly sedate with some fast bits in-between. This is the first time I have driven the Z without any tram-lineing the new rear tyres have made a significant improvement to the handling, can't wait to get the bushes and suspension done now.

The car really does hang around the corners and the ride is very smooth could not be happier, sun out roof down and a car that is starting to work for me.

So some pics of my ride, sorry about the quality just on a phone. The first is North Weald Airfield with the model of a Hurricane and the second is Hatfield Forest.

It's good to take time out to clear the mind, more so in a Zed with the roof down. Great Pic of the mighty Hurricane
Good luck with your dissertation

where abouts in essex are you Windym, im in chelmsford

Now photo 1 is a possible calendar choice

Hi, Potter St, Harlow Common, just off the M11 roundabout.

Great way to take a break. But, you can't say you're doing a dissertation and then not tell us what it's about. You never know, we may able to provide some insight and inspiration - chances are about 100,000 to 1 I'd guess!

Hi, breaking it down to basics i am looking at various points in the visible and invisible light spectrum. To determine if it is possible to detect finger prints on skin. The basis is narrow band imaging where mucosal and sub-mucosal tissue are viewed with part blue/green wavelengths.

The application is in forensic imaging looking at the oils rather than blood and seminal fluids, with the use of chemical compounds and controlled light sources, with the skins natural oils.

Andy

I'm sorry..... did you say bodily fluids?

Now @windym that is a subject I do know something about! It's dangerous stuff if you get it in the wrong place and VERY expensive and leads to the loss of the Z3 amongst other things!

I did say 100,000 to 1 didn't I?
It sounds very interesting though. I'm guessing very thin layers of certain fluids are within the wavelengths of certain frequencies so produce characteristic destructive/constructive interference. Identify those left by skin on fingers around the fingerprint and you have a record.
Sounds like postgraduate research. Good luck.

One practical application, as seen on this very forum is the detection of body,s hastily shoved into the back of Z4,s, @GazHyde @BMBabe. Although there is enough picture evidence for a conviction without the use of forensic imaging. Saying that the amount of said victims DNA floating around a large percentage of Z,s on this forum. Would in my humble opinion negate any prosecution (allegedly) facing said Z4 owner.

Nah - No crime there! @BMBabe is well known for climbing into any bodies Zed at the merest invitation

 

[BMBabe]

@windym So when I sit in other owners Zeds I am still there for a long time then??

OOOhhh yes but to keep it to a minimum try not to sneeze on the steering wheel

Andy, you are in great danger of joining a very elite club with those comments mate. PMSL

I left school with a grade "C" in Religious Studies (that's it), if I can be of any help, please shout up

Its ok when you start looking at what we do and don't see. In normal colour capture/imaging, three colours/filters are used to separate the primary colours of the visible spectrum. These are Red, Green and Blue and relate to the Human visual system or colour sensitivity of the Human eye. Giving in effect a true colour, these filters/colours cover approximately a third of the visible spectrum.

Narrow Band Imaging uses optical filter technology, by separating two specific bands waves of light. One in the blue spectrum at 415 Nano-meters and one in the green spectrum at 540 Nano-meters. This greatly improves subject visibility, capillaries/veins/micro-capillaries and other tissue/mucosal surfaces and structures.

By reducing scattering and reflectance characteristics and at the same time optimising the absorbance of light from mucosal and sub-mucosal surfaces. NB blue light works on superficial epithelial capillary networks. While NB green light highlights sub-epithelial vessels. Combining the two NB wavelengths gives very high contrast imaging of tissue surfaces.

This is the basis of looking at separating light into defined wavelengths. The key is working out what wavelength gives the greatest resolution against the chemical compounds being used. The main problem is there is a very short window of around 15mins after that detection at the moment seems to disappear.

Know what you mean, followed that all the way I can tell you that you need a minimum of 110 bar hydraulic pressure to raise the canopy of the tornado GR1 and the F16 has 6.7 US gallons of H70 Hydrazine on board. Horses for courses Andy. Well out of my depth in your field to the extent I put my arm bands on to keep afloat whilst reading it. Oh, Guiness is good
