No description was provided for this meeting.
If this is YOUR meeting, an easy way to fix this is to add a description to your video, wherever mtngs.io found it (probably YouTube).
C
So
yesterday
we
had
a
complete
schedule.
Today
we
have
no
schedule.
So
the
thing
is
yeah
we're
just
we're
here,
I'm
going
to
try
to
provide
some
information
that
might
be
of
interest
or
use
on
what
hear
from
you
guys
said.
What's
what
you're
doing
and
yeah
I'm
just
gonna
use
the
day
as
reductively?
You
know
it's
possible
sort
of
talk,
something
like
programming,
tutorials
version
whatever,
so
it
really
just
just
depends
on
what
everybody's
interest
with
I.
Don't
you
just
tell
me
your
name,
I
can't
Surrey
and
we'll
just
go
out.
E
A
A
On
the
scene
of
things
off
on
the
time
in
the
range
scale,
interaction
so
that
the
link
between
seismic
scattering
properties
and
the
very
subtle
onset,
material,
finance
or
the
finish
market
right
useful,
but
I,
don't
even
talk
with
you.
Besides,
my
electrics
me
yeah,
it
was
fifty
years
in
terms
of
monetary
meeting.
A
A
Source
monitoring
the
changes
in
meeting
over
time
also
got
a.
We
share,
we're
doing.
Work
on
molecule
is
cyclic.
Presently
she
completed
a
reservoir
and
you
wanted
to
this
kind
of
properties
of
the
medium
grabbed
the
innovation
cycle.
We
can
hardly
replicate
the
pressure
curve.
We
just
put
it
under
excuse
you,
the
pressure
could,
without
making
pressure.
B
F
D
G
D
C
F
B
C
Trying
to
and
there's
been
a
lot
of
work,
especially
a
couple
of
decades
ago,
where
people
took
you
know
the
e/m
equations
and,
and
you
could
write
them
because
you've
got
reflection,
coefficients
right
and
transmission
coefficients.
So
you
can
write
things
in
that
manner.
You
can
actually
solve
problems,
but
when
you
actually
try
to
work
through
that
kind
of
analysis,
it's
it.
You
just
get
kind
of
trapped
up
with
the
fact
that
you
know
these
a.m.
waves.
C
Basically
gonna
go
in
a
fraction
of
a
wavelength
right
because
it's
time
to
get
down
to
one
wavelength,
you're,
basically
e
to
the
minus
2
pi
in
amplitude.
So
it's
it's
a
bit
of
a
different
reason.
Mathematically!
You
can
write
it
in
that
form.
We
actually
formulated
mandatory
inverse
the
1d
empty,
inverse
problem
in
terms
of
finding
reflection,
boundaries.
C
Anything
is
something
actually
it
looked
like
a
seismic,
but
I
haven't
seen
I
really
haven't
seen
applications
where
this
stuff
works.
In
practical
cases,
the
mathematics
works,
there's
been
a
gal
named
mo,
did
some
reverse
time.
Vibration,
electromagnetic
data
and
I
mean
on
paper
mathematically.
It
looks
right,
looks
like
binary,
so
that's
where
you
know
you
take
the
seismic
equations
who
take
the
young
equations
you
can
make
correspondence
is
every
turn
because
in
reality,
because
the
attenuation
is
so
large
and
the
traveling
wave
component
is
so
small.
E
B
C
You
might
have
multiples
also
quality,
yes,
but
the
the
multiples
all
kind
of
get
concatenated
in
with
your
final
wave
field.
So
if
you
solve
the
like
the
empty
equation,
exactly
you're
actually
are
handling
all
of
the
multiples.
Everything
is
in
there.
But
if
you
try
to
recast
it
in
terms
of
up
and
down
going
plane
waves
and
trying
to
keep
track
of
everything,
it
becomes
very
difficult,
very
unstable
and.
E
A
C
Think
these
problems
would
probably
equally
ill-posed
I
mean
there's
a
question
resolution,
but
if
you
accept
that
you're
just
going
to
get
poor
resolution
of
I
think
the
problems
are
essentially
the
same.
You've
got
some
function
that
you're
trying
to
find
your
way
to
discretize.
It
you've
got
some
way
of
solving
for
word
simulation
either
through
some
finite
element,
volume
difference
and
the
procedure
that
most
people
use
big
still
on
seismic
Netherlands.
They
are
just
and
the
Gaussian
procedure.
We've
got
natural
parameters.
C
G
C
The
kind
of
roundup
course
material
that
we
present
it
yesterday,
but
I
think
a
lot
of
its
not
particularly
of
interest,
the
the
only
connection
that
at
least
what
connection
I
can
find
from
material
that
we
actually
have
is
the
induced
polarization
for
landfills.
So
that's
that's
at
least
one
tangible
connection
with
one
person.
G
C
In
North
America,
the
you
know,
the
methods
of
choice
are
magnetics
is
kind,
it
provides
some
information
about
potential
items,
but
you
know
it
takes
up
everything
and
it's
very
hard
to
do
in
Kent
discrimination.
So,
in
order
to
do
discrimination,
you
need
to
use
some
kind
of
frequency
or
time
immune
systems.
Most
of
them
are
time.
Domain
systems
and
they've
now
evolved.
Actually,
it's
really
quite
amazing
for
the
last
five
years
of
how
they
have
a
ball.
We're
associated
with
the
group
called
black
tusk
factor.
C
Most
of
the
people
that
came
through
UBC
started
their
own
company
about
three
or
four
weeks
ago,
at
least
in
Vancouver
paper.
There
was
a
big
flashy
picture
of
the
cleaning
list
of
the
Queen
Elizabeth
aircraft
carrier
going
into
Portsmouth
in
England,
and
they
showed
this
aircraft
carrier
going
in
and
it
was
a
big
deal
for
them,
because
previously
the
channel
to
go
in
was
not
big
enough
to
have
this
size.
The
book
so
last
couple
of
years,
they've
been
spending
kind
of
making
the
channel
wider.
C
C
Achieve
there's
my
DS
C
I
think
it's
close
to
twenty
receivers
pre
component.
So
it's
like
a
sixty
receivers.
C
Multimeters
and
the
idea
is
that
you're
exciting
this
object
from
many
different
directions.
You
know
at
one
particular
time
so
you've
got
all
kinds
of
principles:
you're
cycling
through
these
tax
meters,
measuring
the
components
of
components
with
minion
feel
in
a
time
instance
and
then
you're
inverting
to
try
to
find
a
decaying
dipole.
So
if
you
have.
C
You
know
in
terms
of
the
number
of
number
of
parameters,
so
this
is
just
a
kind
of
a
parametric
way
of
representing
that
that
K,
the
dipole
and
for
an
object
that
has
got
a
bit
of
geometry
to
it.
I
can
actually
have
three
independent
dipoles
that
are
decaying,
so
that
means
instead
of
solving
the
full
3d
electromagnetic
time
main
electromagnetic
problem,
we're
dividing
things
into
those
cells.
You
just
have
a
parametric
representation
so
that
at
each
point,
you're
representing
what
the
fields
are
like
with
three
independent
cackles
each.
B
C
So
you
end
up
with
having
to
find
you
know,
15
or
something
parameters,
but
then
you're
exciting
the
object
from
many
different
different
directions
so
with
and
then
the
way
you
didn't
use
this
as
you
you
find
these
these
values
and
then
you've
got
libraries
to
kind
of
look
up
and
see
how
savings
match
you
can
actually
discriminate
as
to
what
object.
This
is
okay,
so
that's
sort
of
the
that
sort
of
procedure
hardly
anybody's,
using
GPRS
with
magnetics
and
time
to
mean
yeah.
The
thing
that
was
interesting
in
the
Portsmouth
example.
C
C
Data
are
coming
back,
they're,
being
processed
they're,
doing
the
inversion,
they're
doing
the
discrimination
and
that
if
they
find,
if
they
find
that
there
is
a
an
object
there,
that
needs
to
be
remediated
then
right
behind
this
boat,
there's
certainly
another
boat,
but
it's
got
kind
of
a
big
vacuum
cleaner
on
right.
So
it's
blowing
stuff
around
and
sort
of
making
this
item
so
that
it's
quite
clear
to
the
extractive
and
then
you've
got
something
coming
along
with
a
grappling
hook.
C
Hangs
on
to
this
guy
pulls
them
up,
and
then
they
pull
it
out
to
sea
and
they
explode
it.
So
they
found
I,
think
five
or
six
of
these
500-pound
bombs
this
way,
and
then
they
with
that
they
were
able
to.
You
know
then
safely
go
ahead.
Exited
baby
with
us,
but
I
thought
it
was
kind
of
about
I
mean
it's
just
kind
of
like
a
neat
example,
because
it
shows
first
of
all
that
you
need
to,
but
that
you
can't
find
metallic.
So
these
are
conductive
magnetic
objects
right.
C
Well,
maybe
then,
the
two
things
that
we
could
do
this
morning
that
might
be
useful
I
could
talk
just
a
little
bit
about
material
that
we
have
for
landfills.
We
could
just
discuss
the
IP
and
then
we'll
do
a
quick
run-through
on
the
GPR
and
then
that's
this
one
will
be
good,
then
we'll
turn
it
over
and
sound
good.
A
A
A
C
C
C
But
then
gradually
the
city
kind
of
builds
up
and
right
now
here's
the
current
sort
of
outside
boundary
of
the
city,
and
you
see
that
it
encompasses
the
number
of
these.
So
they
create.
You
know:
health
hazard,
there's
water
contamination.
A
lot
of
contamination
is
a
big
thing.
Construction
ever
hazard,
and
but
one
of
the
biggest
things
is
if
you
values
your
property.
C
C
The
techniques
are
generally
used,
our
electrical
resistivity,
but
you
can
see
that
they're
not
completely
completely
uniform.
Certainly
anything
that's
metallic.
It's
got
a
very
low.
Resistivity
construction
debris
might
be
I
earth
materials.
A
lot
of
them
can
be
have
a
lowly
assistant
III
waste.
It's
very
magnetic
susceptibility
is
a
little
bit
all
that
some.
If
you've
got
you
know
scraps
of
iron
or
something
like
that.
C
E
C
D
D
C
C
Here's
the
resistivity,
so
you
do
a
new
series
to
the
experiment.
Here's
the
resistivity
and
you've
got
red
in
this
case
is
really
low,
resistivity
and
greediness.
It's
how
you're
dating
the
outlines
of
the
it's
the
pit
from
the
waist
bound
is
no
historical
basis
is
given
in
this.
So
a
little
bit
all
over
the
map
chargeability.
However,
that
is
it's
good,
so
here's
charge
compressed.
B
C
C
I
have
no
idea
what
what
any
of
this?
Yes,
all
we,
the
only
thing
that's
known
here,
is
here
some
limits
of
the
waist
up
and
here's
what
you
get
up
in
resistivity-
and
here
is
the
so
yeah
so
being
back
at
the
IP-
is
come
in
here
and
actually
coming
up
close
to
the
surfaces
wraps
good.
Similarly,
if
we
look
at
another,
so
that
was
one
that
had
mixed
solid
waste
and
this
one's
got
construction
debris
and
in
this
case
here
we've
got
to
you
know
some
kind
of
glorious
Tiffany.
E
C
That's
your
kind
of
correspondence
when
they
were,
they
have
to
collect
data
over
many
different
lines.
They
inverted
leads
to
these
data
sets
and
then
they
looked
at
the
final
chargeability
and
kind
of
ended
up
with
four
regions.
This
they
wanted
to
do
test
going
to
see
if
that
was
those
effect,
but
they
didn't
want
at
to
drill
on
any
plates
that
have
chargeable
material
of
the
de
Gaulle's
waste
because
they
were
worried
that
a
plant
just
by
putting
drill
hole
through
the
might
contaminate
sinks,
3ds
china,
it's
kind
of
interesting
they.
C
D
C
C
C
So
the
point
about
this
is
that
historical
boundaries
of
waste
are
nicely
and
delineate
by
the
the
chargeable
material
and
all
of
this
low
resistivity
of
here
it's
not
chargeable,
and
that
is
very
likely
the
leachate.
So
what
happens
you
get
stuff?
That's
here.
Water
goes
through
takes
out
of
that
a
lot
of
metals
and
brings
it
down
here,
and
this
is
the
stuff
that
you
people
are
really
worried.
C
A
C
Versus
aisle
Lola-
and
that
was
that's
really
the
kind
of
the
take
home.
The
take
home
point
here,
here's
one
that
this
is
probably
kind
of
like
an
iconic
example.
This
is
what
people
were
looking
for
at
the
so
the
waist
up
was,
and
so
it's
low,
resistivity
and
chargeable.
They
call
it
sighs
yeah.
So
oh
and
here's
somebody
was
mentioning
about
having
to
do
this.
Also,
maybe
do
monitoring
was
that
you
for
the
landfill
really
yeah
so
so
here
here
is
an
example.
With
municipal
weeks
there
was
a
2003
survey.
C
I
think
it
was
2009
so
six
years
after
two
years
after
the
remediation
I
ended
up
with
the
chargeability
section
of
it
looked
like
that,
so
that
was
kind
of
nice.
But
so
for
the
point
of
view
of
monitoring,
you
know,
perhaps
even
the
surface
IP
experiment
done
can
help
you
so
to
see
how
well
you're
doing.
C
G
C
Exactly
what
the
details
are,
but
you
know
when
they're
going
in
and
they've
got,
you
know
they
find
a
place.
That's
contaminated,
then
they're
doing
something
to
try
to
get
rid
of
that
contamination.
So
somehow
the
IP
is
reflective.
How
much
contamination
that
there's
there
and
it's
this
example
show
that
the
radiation,
for
maybe
they
thought
of
it,
was
just
left
to
its
own
devices.
I
think
they've
got
to
be
like
30
years
or
something
like
that
to
really
clean
up
all
by
itself
and
by
going
in
and
actively
remediating
and.
E
C
G
E
C
C
E
C
E
C
C
So
this
is,
this
is
an
area.
It
was
a
landfill
for
ten
years
sort
of
100
meters
by
100
meters,
and
it
was
basically
sludge
for
some
waste
treatment
plant.
A
nest
made
volume
of
about
65,000
cubic
meters,
but
when
they
get
there
was
there
was
no
containment.
There
was
no
way
to
capture
the
meat
chain.
There
was
no
isolation
of
the
system,
they
just
it
is
doped
up,
and
the
current
state
is
that
the
landfill
it's
got:
lots
of
iron
hydrocarbons,
okay,.
C
E
C
Maybe
there's
parts
of
this
that
are
kind
of
similar
to
what
what's
happening
in
fallen,
you've
got
sort
of
an
upper
clay
layer
and
a
couple
of
meters,
and
then
there
is
a
waste
layer
and
then
there's
sort
of
sand
and
gravel
kind
of
interbedded
in
here,
and
maybe
some
no
avataric
still
so.
The
after
itself
is
if
it's
used
for
drinking
and
currently
does
the.
C
C
C
C
Than
what
we
were
sort
of
advocating
a
two
step
process,
and
here
not
at
each
basically
at
each
time,
John,
we
invert
each
time
chalant
eventually
and
we
get
out
something
sort
of
a
suitable
target.
Bility
here
never
had
that
current
of
people
ask
somebody
has
to
vote
that
chargeability
curve,
whether
that
was
typical
or
not
and
I
said.
Well,
it
really
comes
from
a
coal
coal
model,
so
here's
a
representation,
that's
very
common
or
the
complex
resistivity,
so
Rho
naught
is
the
resistivity
at
DC.
C
M
naught
is
the
chargeability
intrinsic
charge,
building
with
0,
1
and
tile
is
time
constant
and
C
kind
of
capsule
eights
the
frequency
dependency.
So
this
is
the
description
of
the
complex
roots
acidity
and
you
can
formulate
the
inverse
problem
so
that
you
have
a
number
of
layers,
and
each
of
these
has
got
its
own
suite
of
parameters,
so
you've
protected
me
the
problem
more
challenging,
though,
because
now
every.
C
E
C
C
Also
edible
they're,
very
cool
I
think
do
they
have
well
I
sure.
C
C
So
there's
this
person
up
here.
The
important
point
is
that
as
these
lines
go
through,
so
the
data
goes
through
they're
inverted
and
here's
the
chargeability
section
that
is
obtained
through
one
line.
Another
line,
and
these
arrows
that
you
have
here
indicate
the
historic
perspective
where
the
boundaries
of
the
way
stuff.
C
You
can
see
that
the
inversion
for
the
chargeability
has
done
pretty
nice
job
in
delineating
that
now
they
could
kind
of
interpolate
the
chargeability
section
and
now
get
certain
3d
representation.
And
then
you
could
use
a
cut-off
value
which
they
used
here,
100
millivolts
per
volt,
and
then
that
gives
them
this
as
an
estimate
of
the
volume
of
the
of
the
waste
and
actually.
C
Kind
of
came
up,
these
quotes
like
50,000
cubic
meters.
First,
that
will
all
depend
upon.
You
know
whole
bunch
of
things
with
an
isosurface
level
in
stuff,
but
you
know
it's
a
first
shot
that
was
actually
pretty
interesting
comparison,
so
that
did
a
good
job
on
locating
and
finding
the
volume
and
then.
C
C
E
C
That
layer
is
also
charged
in
so
if
we
take
a
log
that
is
sort
of
coming
through
here-
and
we
plot
it
up
here,
what
we
have
is
the
resistivity
in
blue,
so
it's
highly
resistive
right,
ethics
of
step,
ID
resistant
surface
and
then
it
drops
down.
So
it's
very
low
resistivity
did
that
comes
out.
The
black
line.
That's
plotted
in
the
background
is
the
gamma
log
and
the
gamma
log
sort
of
increase,
yes,
start
slow
increases
and
then
goes
down.
So
that's
typical
of
a
link
of
a
play.
E
C
You
tell
low
resistivity
and
a
high
high
gamma
gamma
the
charge
ability
does
the
same
kind
of
thing
since
that
it
actually
has
a
high
charge
ability
at
the
clay
layer,
and
so
it
looks
like
that.
So
here
you,
your
resistivity
Indiana,
are
anti-correlated
here,
charge,
ability
and
mo
are
correlated,
and
you
end
up
with
a
region
in
here
that
has
got
high
gamma
high
charge.
Ability
at
low
resistivity
so
interpret
that,
as
as
a
claimant.
C
Coming
down
into
a
more
intermediate
section,
there's
a
claim:
rich
sad
need
layer!
That's
what's
in
here!
So
it's
it's
this
region
in
here.
So
it's
got
a
rather
high
resistivity.
So
it's
it's
sort
of
sad
me
play
that
expected
to
have
a
high
resistivity.
The
charge
ability
is
expected
to
be
moderate
and
you
see
that
here
and
the
gamma
should
be
very
fairly
hot.
So
if
you
look
at
these
logs
here,
that's
basically
what
you
and
then
what
we're
seeing
as
far
as
as
a
correspondent.
So
we've
got
this
relatively
high
charge.
E
C
C
This
clay
layer
up
here,
okay,
that's
got
a
low
resistivity.
Okay,
so
that's!
This
is
how
I'm,
just
okay,
so
you've
got
a
play
there.
It's
got
low
risk
to
me
and
then
you're
coming
down
into
another
sort
of
information
that
still
hasn't
play,
but
there's
a
lot
of
sand.
Maybe
it's
sad
and
it's
got
something
so
I'm
claiming
right,
yeah.
E
C
A
Like
in
though
others
do,
generally,
you
just
say,
I
think
they
all
know
will
not
know
that
very
often
you
get
very
basic
like
high
gamma,
even
claim
and
lower
the
same,
but
all
the
Cajun
you
get
radioactive
sands.
You
just
throw
that
into
your
page.
Now,
no
good,
okay
and
you
have
it
leave
service,
probably
more
often
than
you
do,
throwing
it
yeah
they're
ready
to
go
high.
A
C
It's
good
after
that
that
third
layer,
if
they
were
looking
for
a
you,
know,
silk
clay
lands
so
they're
looking
for
something
that's
low,
resistivity
pie
chart
to
built-in
high
down
and
right
at
they
be
at
the
bottom
area.
Here
in
the
god
dirty
low
resistivity
we've
got
high
charge
ability
and
in
this
region
you
can
here,
we've
got
moderately
high
camera
batteries.
So.
E
C
C
C
C
D
C
E
B
C
This
is
this
is
kind
of
interesting
up
here.
So
if
you
look
at
I
mean,
let's
just
take
this
at
face
value
and
just
see
what
there
is
a
bit
of
a
difference
here.
So
this
is
low,
resistivity,
so
very
low
here
at
high
charge,
filter
here,
okay,
but
above
here
the
charge
ability
gets
less
and
here
resistivity
is
also
bit
higher.
But
it's
still
pretty
pretty
low
resistivity.
C
The
point
about
that
that
might
have
some
physical,
meaning
and
understanding
I
think
it's
encapsulated
kind
of
in
this
diagram
that
they
put
through,
which
is
Panem
cartoon
on,
what's
happening.
So
here's
here's
the
waste
and
then
there's
that
upper
layer
here
that
clay
layer
and
they
believe
they've
listed
that
as
an
aquitard
of
you
and
the
reason
that
the
only
reason
that
they
gave
for
that
in
the
paper
was
that
okay,
we've
got
it
as
a
clay
layer
and
then
there's
a
screen
over
top
of
it.
So
we're
thinking
that
this
is
I,
don't.
C
Sufficient,
that's
that's,
basically
what
they
said,
so
they
listed
that
top
clay
layer
as
an
avatar,
and
then
they've
got
this
clay
rich
sandy
layer
coming
in
here
and
to
play
lens
at
the
bottom.
Okay.
Now,
in
addition
to
that,
there's
this
flute-
that's
contaminant
leachate
is
coming
down
and
it's
so
it's
coming
down
sort
of
being
yeah
truncated
by
this.
C
This
clay
lens
and
then
is
if
that
cartoon
is
true-
and
you
transfer
that
to
to
here
then
we'd
expect
to
have
higher
conductivity
or
lower
resistivities
that
are
going
upwards
above
the
plate
limbs,
which
you
know.
Maybe
you
know
it's
a
bit
more
reflective
of
what
this
so
at
least
at
least
from
the
point
of
view
of
a
story
which
I
can't
elaborate.
It's
not
our
work,
you
know
everything
kind
of
fits
together
and
when
they
do
the.
G
C
So
that
I
think
this
is
the
this
is
thinking
when
you
do
the
resistivity
and
conversion
that
you
get
something
that
looks
like
this.
So
here
is
the
here's,
the
waste
stock
right
and
then
you
you
get
this
high
high,
conductivity
or
low
resistivity.
So
it's
kind
of
a
blue.
That's
it's
coming
out
this
way
and
that
low
resistivity
can
be
caused
by
two
things.
One
is
it
could
be
that
plane
lands
at
the
bottom,
but
also
the
leachate
is
it
has
a
low
resistivity.
C
So
this
line
it's
p4,
if
you
cross
that
so
here's
the
result
of
the
resistivity
aversion,
so
there's
this
low,
resistivity
blocked
and
sitting
in
there,
and
if
you
look
at
that
line,
that's
sitting
out
here.
So
it's
quite
a
ways
away
from
the
waist
down
yeah
and
then
the
next
slide
has
taken
this
same
thing
and
plotted
out
on
a
section.
So
here
is
this:
this
line
is
coming
through
here,
there's
a
section
on
which
they
build
a
number
of
holes
profile
for
the
lines
right
in
here.
C
That
scale
is
a
bit
hard
to
read
in
this
room,
but
this
is.
This
is
really
the
highest
value
of
the
coronated
compounds
that
are
sitting
there
and
that
matches
actually
pretty
nicely
with
this
guy.
So
there's
you
know:
go
through
they've
evaluated
the
amount
of
metal
ions
in
good
there's
a
lot
of
them
at
a
depth
that
kind
of
matches
here
so
part
of
that
clue
is
definitely
lychee.
C
C
Think
the
first
aspect
of
trying
to
delineate
the
boundaries
of
weights
and
the
volume
from
the
IP
has
been
that
that's
really
that's
really
stable.
The
delineation
of
the
Lee
jae-hoon
I
think
just
by
looking
at
that
high
recent
hike
on
attending
low
resistivity,
that's
coming
out
from
the
waist
outside.
That's
probably
a
pretty
good
interpretation,
and
then
you
know
their
assessment
of
them,
trying
to
simplify
the
geology's
and
the
sounds
and
plays
into
something
that
looks
like
this
kind
of
matches.
The
gamma-ray
chargeability
emissivity
I
mean
yeah.
C
F
C
C
C
A
A
C
G
E
G
C
C
Saltwater,
freshwater
interface,
there's
been
applications
for
there.
A
lot
of
work
done
in
a
very
near
surface
engineering,
geotechnical,
work
for
finding
underground
tanks,
archaeology
doing
and
Rock
glaciers.
We
have
a
case
history
go
through
that,
so
just
to
kind
of
briefly
go
through
the
basics
pair
with
physics
bit
of
day
processing,
not
very
much
meant
a
Stella
field.
Examples
and.
C
Small
anyway,
so
this
is
the
basic
unit
at
the
transmitter
receiver.
So
this
works
very
seismic
goal-oriented
and
fact
all
the
pictures
here
could
be
so
precise
me
instrument
and
we've
got
rays
that
and
coming
down
and
reflecting
off
their
stuff,
that's
being
transmitted
and
in
the
end
you're
going
to
be
plotting.
Radar.
C
Look
pretty
much
like
a
seismic
section,
so
the
basic
equations
we
had
yesterday,
but
now
the
thing
that
is
on
grade
is
this
quantity
here,
which
is
the
displacement
curve.
So
here's
this
is
reading.
The
wave
propagation
curtain
comes
in
here
to
make
the
second-order
system,
and
we
showed
it
yesterday
paper
two
equations
and
put
them
together.
E
C
Seismology,
it's
ten
great
things,
but
what
we
did
everything
yesterday,
because
this
is
so
big,
basically
Sigma
and
oh
my
god,
it's
my
screen
Epsilon
this
guy
is
we
ignore
it,
but
we're
not
going
to
know
the
quantity
of
interest.
Is
the
electrical
permittivity
and
velocity
of
the
electromagnetic
wave
is
velocity
of
light
divided
by
the
square
root
of
the
dielectric
constant,
so
the
dielectric
constant
is
really
the
ratio
of
the
electrical
permittivity
of
the
material
divided
by
the
permittivity
of
free
space.
G
C
C
Nakamoto
skin
death
in
a
big
quasi
static
regime.
This
was
the
skin
depth
formula
mean,
so
we
use
that
all
yesterday
and
we
locked
at
the
skin
depth
as
of
frequency
in
that
class
and
static.
You
mean
it's
looking
like
this,
but
if
we
increase
the
frequency,
then
now
the
wave
equation
term
starts
to
increase
and
we
end
up
that,
be
let's
get
that
kind
of
asymptotes
out
here
and
doesn't
change
nearly
as
much
with.
B
C
C
C
C
So
in
those
high
frequencies,
then
yeah
we
do
have
kind
of
take
this
path
right.
So
we've
got
direct
waves
in
the
in
media.
We've
got
airway,
it's
going
to
travel,
speed,
light,
we've
got
reflected
waves
and
we've
got
we
come
down
back
up
and
then
they
get
refracted
at
the
very
surface
and
then
so.
The
refraction
is
kind
of
interesting
because
the
highest
velocity
is
actually
here
in
the
air
and
so
the
major
attractions
they.
C
B
C
Well,
is
there
any
success
analogy
here
for
processing
because
you're
working
at
such
high
frequencies,
here
hundreds
of
megahertz
to
gigahertz?
This
way
you
you
know,
even
if
you're
pulling
the
instrument
along,
it's
recording,
you
know
thousands
of
realizations
of
your
say.
You
know
fact
you
can
keep
it
important
to
do
a
lot
of
stacking
and
that
allows
you
them
to
gradually.
You.
C
E
C
Get
a
radar
signal
and
here's
what
a
typical
Craner
gram
would
would
look
like.
You
can
see
that
there's
some
reflections
or
some
reflections
in
this
near
surface
and
then
there's
these
hyperbolic
types
of
structures.
So
those
hyperbolic
vectors
are
obtained
just
because
you've
got
a
source
and
receiver
that
are
moving
across
here
and
there's
some
kind
of
reflection.
That
is
happening
and
as
you
move
across,
and
it's
just
thing
that
used
to
with
size
and
travel
times
that
tell
you
in
that
pulse,
that's
going
to
become
you.
C
E
C
C
You
can
use
these
things
become
in
various
frequencies,
the
size
of
the
instrument
or
really
the
antenna.
That's
in
each
much
is
inversely
proportional
to
the
frequency
that
you're
working
with.
So,
if
you're
at
a
very
high
frequency,
you
know
in
the
gigahertz
you
can
make.
The
whole
system
looks
like
this,
and
you
know
here's
a
guy
looking
for
cables
that
I
think
I'm
a
geek.
So
it's.
C
Here
and
he's
got
to
display
up
here,
it
kind
of
did
real-time.
You
can
figure
out
cable,
sorry,
here's
an
archeological
experiment.
You
can
also
have
the
antennas
not
in
that
close
box,
but
they
could
be
separated.
So
you
actually
do
like
a
common
midpoint
type
survey.
That's
actually
useful
for
estimating
what
the
dielectric
constant
is
in
this
region.
C
E
C
Help
then
you've
got
a
conversion
from
time
to
death,
so
just
the
same
in
size
me,
you
know
it's
easy
to
get
something
in
terms
of
time.
It
really
would
like
to
have
it
in
terms
of
deficit.
You
need
to
know
something
about
the
velocity,
so
you
can
do
a
common
midpoint
experiment,
get
information
about
the
velocity
and
then
gives
that
to
convertible
time
today
and
yeah.
This
is
the
more
common
one.
You've
got
everything
in
one
box
and
you're,
just
the
common
offset
of
zero
offset.
E
C
C
See
there's
some
horizontal
reflectors
in
here
there's
a
couple
of
objects
that
are
giving
rise
to
hyperbola
and
there's
a
blanked
out
region
in
here.
So
that's
kind
of
interesting
like.
Why
are
we
losing?
Why
is
the
signal
so
poor?
You
here
prepared
here?
If
you
then
subsequently
go
and
do
a
DC
resistivity
survey
across
here
and
invert
that
you
get
a
resistivity
map
that
looks
like
this.
This
red
region
is
a
low
resistivity,
so
low
resistivity
means
that
there's
good
before
attenuation.
C
C
Yeah
so
here's
the
other
case
again.
Here's
the
tanks,
I
kind
of
showed
you
that
that
before
and
you
can
do
take
the
you
know
the
radar
grams
in
yep
due
to
all
kind
of
3d,
3d
ball
in
greater
grams,
and
then
you
can
convert
the
time
to
death
and
now
you've
got
particular
yeah
slices.
So
at
freedom,
three
and
a
half
feet
see
that's
at
five
feet.
You
see
more
of
this
bottom
tank
bit
and.
C
C
Map
keep
thickness.
This
is
an
example
of
somebody's
just
towing
a
system
along
here.
This
was
in
Ireland
and
just
tow.
The
system
keep
track
of
where
you
are
with
the
GPS
and
some
kind
of
a
wheel
counter,
and
you
get
a
system
it
was
out.
There
looks
like
this.
You
can
tell
where
that
peach
layer,
yes
and
they
actually
mined
this
students
in
Ireland.
F
C
E
C
E
C
So
that
was
good.
I
can't
showed
you
this
the
other
day.
You
know
I
just
thought
this
is
so
cool,
and
it's
actually
one
of
these
things
that
I
think
are
really
important
for
connecting
with
you
know
the
average
guy
on
the
street
as
to
you
know,
electromagnetics
and
yeah
it
just
just
kind
of
resonated,
and
so
the
the.
C
Is
work
that
was
done
with
an
MIT
with
the
Lincoln
labs?
Is
that
they're
concerned
about
what
sort
of
sensors
can
be
used
for
cars,
especially
in
that
environment?
See
here's
a
it's
a
bit
of
a
fence
a
bit
of
an
overkill,
but
here's
the
car
and
where
the
car
is
with
respect
to
everything
else.
So
you've
got
a
GPS.
E
E
G
C
C
So
now
you
can
now
you
come
along
with
your
car
in
another
four
conditions,
but
you
so
you
can't
maybe
see
your
optical
sensors
are
not
working
so
well
here,
but
you
can
still
see
into
the
ground.
So
it's
a
shallow,
but
you
can
see
you
can
see
down
and
that
region
is
not
really
affected
by
the
fact
that
there's
you
know
a
little
bit
of
rain
or
there's
some
fog.
C
So
now
you
get
this
radar
ground
that
that's
coming
in
and
you
do
a
cross
correlation
of
this
signal
with
their
library
signals
and
try
to
find
out.
You
know
the
norming
and
easting
location
in
which
you've
got
that
highest
quality,
correlation
and
then
okay.
This
is
at
this
particular
moment
in
time
at
this
spot
yeah.
That's.
A
B
C
C
A
A
A
E
A
C
A
Here
in
the
Netherlands
they
play
to
use
like
in
by
natives,
we
take.
There
are
many,
many
other
charging
stations
and
they
are
divided
by
the
council,
so
it
cars
coming
plug-in
and
it
uses
off-peak
storage
for
the
event
people
now
release
used
to
challenging
new
in
placing
low
consumption
times,
and
then
this
first
part
of
it
that
be
charged
when
the
grid
reads
more
power.
A
That's
what
test
we're
trying
to
do
that!
That's
why
every
single
one
of
the
house
has
released
now
have
a
full,
automated
dragon
capability
because
they
want
to
require
huge
data
set
of
roads,
which
is
what
will
be
needed
by
all
the
other
time.
This
is
going
on
that,
that's
it
so
because
you
need
that
to
the
allergy
drive
performance
and
you
need
to
have
this
digital
rattlesnake
look.
G
C
Problem
with
the
landfills,
but
you
know
the
other
thing
that
I
found
really
I,
don't
know
kind
of
inspirational
over
the
last
couple
weeks
is
when
you
turn
on
in
these
news
broadcasts
and
they're
they're
talking
about
the
hurricane
because
they're
come,
you
know
so
they're
a
disaster
in
there,
yeah
I'm,
just
you
should
terrible
in
that
respect.
Herman.
The
positive
aspect
was
from
Canadian
viewpoint.
We
were
looking
at
the
projections
of
where
hurricane
Harvey
and
now
her
mom,
especially
Burma.
It
was
going
and
they
started
they.
C
E
C
They're,
just
really
really
different
and
everybody
started
up.
Energy
is
the
same
and
there
was
clearly
a
whole
bunch
of
other
tracks
kind
of
in
between,
but
initially
it
started,
and
then
they
and
then
in
a
day
or
so
later
you
can
start
to
see
things
still
still
Leopard
and
then
it's
not
white
they're
like
they
both
have
okay,
no
we're
going
this
way
right
and
just
that
whole
concept
of
kind
of
uncertainty
and
predictability
with
models
like
okay
they're.
A
A
Yeah
but
right,
but
the
the
point
being
of
the
modelers
know
that
models
are
essentially
the
uncertainty
in
that
particular
exact
position
is
quite
I.
The
moment
could
have
very
easily
produced
a
right
to
directory
or
a
lefty.
They
bring
it
down
so,
and
you
would
like
to
see
the
old
for
that
yeah
and
then
you
know
certainly
people
that
serve.
C
You
know
there
is
some
insight
about
mentor
just
because
you're
showing
only
model
rigs
and
I
think
that's
great,
because
politicians,
everybody's
you
know
like
okay,
tell
me
exactly
what
is
but
here's
a
case
where
it's
been
proven.
It's
very
valuable
information,
that's
come
home
and
there
is
clearly
some
variability
in
what
those
predictions
are.
A
They
live
in
earthquake,
the
earthquake
happened
and
then
the
authorities
were
getting
a
lot
of
heat
because
a
lot
of
the
money
that
was
meant
to
go
into
reinforcing
buildings
just
going
to
politicians,
comments
about
a
fractionate
that
probably
Cleveland
hated
their
authorities
through
the
seismologist
in
jail
Elster,
and
then
there
was
actually
from
here
and
under
european
we're
putting
a
lot
of
pressure
on
the
local
authorities,
these
people,
because
so
as
long
as
it
doesn't
go
that
direction
like
the
public,
like
what
you
model
say
recently
didn't
happen.
Yes,.
H
E
H
H
So
the
way
it
looks
now
we
have
to
clean
this
collecting
clean
this.
Each
ID
starts
the
next
fifty
or
hundred
years.
So
we
want
to
clean
the
lens
lot
quicker
with
treatment
methods.
So
the
new
changes
is
clean,
so
we
can
just
release
the
damn
show.
We
don't
have
to
care
about
collecting
collecting
these
discharges,
and
you
think
this
was
actually
put
together
like
3040
years
ago.
F
C
A
G
E
H
H
E
E
H
The
invoice
itself
it's
decorative
so
in
some
of
them
their
first
leachate
recirculation
and
then
start
aeration
in
other
ones.
They
start
iteration.
They
meet
and
yeah
I've,
been
from
a
PC
I've
been
working
on
modeling,
this
type
of
behavior.
So
how
do
we
shake
loads
up
and
how
kind
of
betrayed
you
get
in
timing
and
we
we
developed
a
model
which
actually
is
based
on
the
hydrology
and
the
biodegradation
inside,
and
it
predicts
in
time,
but
the
leachate
quality
will
be-
and
it's
important
well,
of
course,
with
its
second
in
certainty
but
yeah.
H
E
H
After
the
treatment
period,
so
we
want
to
improve
this,
we
have
a
basic
model,
but
we
want
to
reduce
the
uncertainty
in
the
modeling
and
ever
we
need
more
data.
So
that's
why
the
next
two
years
we
want
to
focus
on
getting
more
data
through
ERT
for
DC
measurements
and
DDS
measurements,
the
distributed
temperature
sensor.
So
while
they
were
draining
the
holes
and
installing
the
aeration
filters,
we
have
installed.
H
H
Hopefully
also
did
DC
measurements
can
implicate
the
information,
but
water
content.
It's
one
of
our
main
hypotheses
now.
Is
it
the
water
that
goes
through
follows
through
in
preferential
flow
paths
and
you'll
also
have
zones
where
water
is
retained,
which
is
more
less
more
immobile
water.
Where
most
of
the
degradation
takes
place,
then
you
have
an
exchange
of
compounds
from
these
bigger,
immobile
water
regions,
foster
flowing
water
and.
D
A
H
Fiber,
which
is
connected
through
a
river
temperature
over
the
whole
cable
and
once
and
we
are
now
trying
out
to
test
measurements
of
weeds
for
the
ERT,
relay
a
service
line
along
one
line
burrows,
and
then
we
try
to
good
spacing
of
two
liters
spirit
electrodes
you
liked
it
the
whole
line
to
get
images
with.
Actually
we
are
still
looking
at
trying
to
find
the
best
DC
or
maybe
IP
method
to
do
to
capture
water
context.
So
the
electrons
in.
H
C
H
C
H
H
Think
muscle
stupidness
been
working
on
trying
to
find
the
right
combination
of
injection
and
measured
points.
So
now
he
keeps
yeah
bond
pair
of
current
approach.
Then
we
fixed
and
measure
different
points
voltages.
Then
he
goes
in
and
gets
it
at
many
different
points
and
then
II
and
then
we
pick
another
injection
point
and
then
we
measure
again,
but
we're
still.
E
H
A
Doing
that
work
for
these
PhD,
he
was
seen
those
countries,
and
so
he
probably
he
Albert
was
importantly
until
you
meet
a
man,
but
he
will
have
a
lot
to
say
about
what's
the
best
configuration,
because
he
oh
good,
know
that
quality
the
same
configurations
and
they
had
four
hundred
four
wells.
We
twenty-something
30
record
well
they're
the
line
of
modern
music,
see
something
that
they
were
everything
not
moving
of
the
blue
like
a
time
thanks.
D
D
H
In
order
to
try
and
we
didn't
yeah,
we
want
to
have
the
system
working
for
ten
years,
so
we
we
were
looking
for
something
it
doesn't
corrode
if
we
can
special
each
it.
So
what
we
make
it
is
a
copper
wire
entrance
to
a
buyer
of
carbon
fiber
and
then
this
connection
we
connected
and
we
should
love
with.
H
H
H
A
B
H
B
C
C
E
H
Environment
polishes
for
most
of
the
compounds:
that's
okay:
they
they
are
below
the
threshold
value,
but
some
of
them
are
way
too
high,
so
that
once
we
are
targeting
on
the
matter
where,
in
sister
chloride,
concentration
needs
to
be
diminished
and
ammonia
concentration
is
high
and
chlorides
I
used
to
get
it
up
by
my
dilution
with
a
teaching
but
ammonium
we
could
could
be
removed
by
my
generation
treatment,
because
then
you
can
oxidize
among
em
to
not.
You
can
get.
