renewal
Renewal theory is the branch of probability theory that generalizes the Poisson process for arbitrary holding times. Instead of exponentially distributed holding times, a renewal process may have any independent and identically distributed (IID) holding times that have finite mean. A renewal-reward process additionally has a random sequence of rewards incurred at each holding time, which are IID but need not be independent of the holding times.
A renewal process has asymptotic properties analogous to the strong law of large numbers and central limit theorem. The renewal function
m
(
t
)
{\displaystyle m(t)}
(expected number of arrivals) and reward function
g
(
t
)
{\displaystyle g(t)}
(expected reward value) are of key importance in renewal theory. The renewal function satisfies a recursive integral equation, the renewal equation. The key renewal equation gives the limiting value of the convolution of
m
′
(
t
)
{\displaystyle m'(t)}
with a suitable non-negative function. The superposition of renewal processes can be studied as a special case of Markov renewal processes.
Applications include calculating the best strategy for replacing worn-out machinery in a factory and comparing the long-term benefits of different insurance policies. The inspection paradox relates to the fact that observing a renewal interval at time t gives an interval with average value larger than that of an average renewal interval.
Hi folks,
I'm a bit concerned with what the Gas Transporter is proposing regarding a replacement pipe install to the properties in the close I live on. The demographic is predominantly elderly, but it seems to be the contractors have gone a bit kamikaze & seem obsessed with finishing early...

having a light hearted debate with a mate about a job he’s on.
Renew a bath.
Existing bath is tiled down on to and it’s about 30mm lower than the panel for the new bath.
Customer doesn’t want any tiles removed.
So would you fit new bath up to the tiles and cut the panel..
Or
Fit bath at the...

Hello there,
I've heard some rumors that to work as gas safe register you have to pay something like 5000 pounds a year or so just for the license...Is it true or not?
hi
I have a leak in the bottom of my loft water tank, I think it's a 50 gallon one but I'm not sure. The measurements are 45inches by 23inches wide,23inches deep
It's going to be really hard to get it out and to replace it as it seems to have been built into place I might get it out if I...
How long do GSR take to re-instate on their register after renewal?
My registration had lapsed and I had no reminders from them at all, even thought the woman on the phone said this should have happened automatically.
Now I can't register a boiler installation with Baxi, and I won't be on the...
Just had renewal through 1st price £195. quick phone call to them, saying had better price from Post Office and they reduced it to £111.00, Maybe next year they will pay me to use them !!
Another year's no claims on all 3 vans... Aviva have decided to up our insurance by 50% lol.
I don't understand why insurance companies do this, are most people stupid and don't they shop around or something? Do people really not question a 50% price hike with an extra year's no claims...

in the last five years i've never once come across 2 open flued appliances in the same room and dont believe its exists anywhere in the country, but its in the book so apparently i have...
Hi all, just been on Gas Safe website to pay for my renewal and have only been asked to pay £90 :/
Very confusing as i thought it was 155+ the dreaded. So now i'm worried if i've cocked up and done something wrong, this happened to anyone else? Can't think of any reason for it to be £90
Thanks...
A friend has a kitchen swivel mixer tap which needs both the compression washer valve cartridges renewed but I am unable
to find replacements of a suitable depth, niether compression
nor ceramic. I have an identical mixer in my kitchen.
The seats are about 35mm below the tap housing entry hole...
