Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.
Let's dive deeper into the world of ODC! Ricardo Alves (OutSystems) will join us to tell all about the new Data Fabric. After that, Sezen de Bruijn (OutSystems) will get into the details on how to best design a sturdy architecture within ODC.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

8. History of Man’s Quest to Fly
• One of the earliest recorded accounts of manned flight is an ancient Greek
myth that tells of a father and a son who were imprisoned on the island of
Crete. They decided that the only way to escape was to fly. Secretly, they
collected feathers from sea birds and wax from bees to make wings for
their arms. When the time came, the father, Daedulus and his son, Icarus,
quietly melted the wax onto their arms and mounted the bird feathers to
make wings. When the wax was cool, they started flapping their wings and
took off over the Aegean Sea in hopes of reaching freedom. Daedelus
warned his son not to fly too high or the sun would melt the wax on his
arms. Icarus was having too much fun and disregarded his father’s
warning, flying closer and closer to the sun. Eventually, the heat from the
sun melted the wax on Icarus’ wings and he plunged to his death in the
sea.
9. • Around 1299 A.D., it was written that the
great explorer, Marco Polo, saw Chinese
sailors attached to kites being used as military
observers.
10. First Powered Flight
• The first true powered flight, with humans on
board, was in a hot air balloon and the event
occurred in France during the 18th Century.
Brothers Joseph and Etienne Montgolfier,
created a manned hot air balloon. On
November 21, 1783, pilot Pilatre d’Rozier and
Francois d’Arlandes, made a historic 25 minute
flight over Paris.
11. Nature’s Flying Machine
• There are two phases of bird flight – a ground
phase and a lift phase. The ground phase
allows the bird to get started moving forward
in order for the wings to provide the
necessary lift.
• The flight feathers work like the propeller of a
plane; i.e., they push downward and
backward, thereby driving the air backward
and moving the bird forward.
12. Natures Flying Machine con’t
• On the down beat of the wing, the feathers
are pressed together so little air can pass
through them. On the up stroke, the feathers
open.
13. Daniel Bernoulli
• Holds an honored place in the history of
aerospace science.
• His discovery of the relationship between
pressure and fluids in motion became the
cornerstone of the theory of airfoil lift.
14. Bernoulli’s Principle
• He found that a fluid, like air in motion , has a
constant pressure. However, when that fluid is
accelerated, the pressure drops. Therefore
Bernoulli’s Principle states as the velocity of a
fluid increases, the pressure decreases.
• Wings are designed to make air flow go faster
on the top. This in turn causes the pressure to
drop and the wing moves upward, against
gravity.
15. Sir Isaac Newton
• Isaac Newton received the highest honor
when he was “knighted” for his work in
science. That is why we call him “Sir” Isaac
Newton today.
16. Newton’s Three Laws
1. An object at rest will remain at rest unless
acted upon by some outside force.
2. A force acting upon a body causes it to
accelerate in the direction of the force.
Acceleration is directly proportional to the
force and inversely proportional to the mass
of the body being accelerated…
3. For every action, there is an equal and
opposite reaction.
17. More Newton
• Newton’s third law is one of several that is
used to explain how an airplane is lifted
against the force of gravity.
• The oncoming wind becomes the action and
the upward movement becomes the reaction.
18. Newton’s Law Put to the Test
• When the airplane is sitting on the ramp or
runway, it is a body at rest. In Newton’s first
law of motion, “a body at rest will remain at
rest unless acted upon by some outside force.”
in this case, the outside force is the thrust of
the propeller or jet engine.
19. Bernoulli’s Principle Put to the Test
• The upper surface of an airplane’s wing is
designed to have a greater curvature or
camber. This greater curvature causes the
oncoming air to flow much faster over the
curved upper surface. As the airflow speeds
up, the pressure drops on top of the wing and
this creates a suction. With low pressure on
top and high pressure underneath, the wing
has nowhere to go but up.
20. The Mathematics of Wing Lift
• Lift = cL x R x ½ V2 x A
• cL is the coefficient of lift.
• R is the density of the air
• ½ V2 relates to the velocity of the air over and
under the wing.
• A is the area of the wing
21. Relative Wind
• A wing, creates lift as it moves through the air.
Once the airplane starts to move forward, a
wind starts blowing in the opposite direction
flowing over and under the wing. This airflow
is known as the relative wind.
22. May The Force Be With You
The Four Forces of Flight
• The Two Natural Forces
- Drag works against Thrust
- Gravity Works against lift
• The Two Artificial Forces
- Thrust Works against drag
- Lift Works against gravity
23. The Three Axis
• Lateral Axis – an imaginary line that runs the
width of the airplane; this controls the pitch.
• Longitudinal Axis – this is the line that runs from
the tip to the tail of the airplane; this controls the
roll.
• Vertical Axis – along with the lateral axis and the
longitudinal axis this will create the center of
gravity; the vertical axis controls the yaw, don’t
get vertical axis confused with horizontal axis,
there is no such thing.

To Fly By The Lifting Power of Rising Air
• Important terms:
• Altitude – the height or distance above a reference plane.
• Aspect Ratio – the ratio between the span of the wing and the
chord length
• Glide Ratio – a mathematical relationship between the distance the
aircraft will glide forward to the altitude loss
• Lift to Drag Ratio – this ratio is used to measure the gliding
efficiency of an aircraft
• Stability – the atmosphere’s resistance to vertical motion
• Thermal – a column of air that moves upward
• Tow Plane – usually a single-engine airplane that will pull a glider
from the ground to an altitude where it can be released
37. The Sun
• How does the sun affect the soaring
conditions within the environment?
• Even though the sun is 93,000,000 miles away,
it provides energy that causes our atmosphere
to move both horizontally and vertically. This
vertical motion provides lifting power for
sailplanes.
38. Components of a sailplane

Pilot tube Rudder
Cockpit

39. Gliders and Sailplanes
Gliders – an aircraft that is towed to altitude,
then floats back down to earth
Sailplane – an aircraft that is towed to altitude,
then soars on the energy of the environment
The pilot of a sailplane uses every method
possible to find lift and then to ride it to a
greater height.
40. Lapse Rate
• When the surface of the Earth gets warmed by
the Sun, the surrounding atmosphere is
heated and this causes the air to rise. This
vertical motion happens because of a change
in the density of the air. As the air becomes
less dense, it tends to get lighter.
• Normally, the temperature will drop at a rate
of 3 ½ degrees F. for every 1000 feet of
altitude gained.
41. Ground Effect
• When the glider comes within a few feet of
the Earth’s surface, it has a tendency to want
to keep flying. This phenomenon is known as
the Ground Effect.
• Spoilers enable them to overcome this
tendency to “float.”
42. Spoilers
• Also known as the divebreaks, spoilers are
located on the wings of a sailplane, the
purpose of spoilers is to disrupt airflow over
the upper camber of the wing. This causes a
loss of lift and an increase in the rate of
descent. In a steep angle of descent, they can
be also deployed as brakes, hence the word
“dive brake.”

Balloons – They Create Their Own Thermals
• Important Terms:
• Buoyancy – to rise or float on the surface of water or within
the atmosphere
• Burner – the heat source for filling the envelope with hot
air
• Envelope – the main body of the balloon usually made of
nylon
• Montgolfer – the name of the two French brothers who
created the first successful manned hot air balloon in 1783
• Propane – a lightweight, low carbon fuel used in hot air
balloon burners
• Wicker – a form of wooden construction used in the
baskets (gondolas)
56. Balloons Were First
• It was not until November 21, 1783, that a
successful manned, powered flight was made.
That monumental event took place in a hot air
balloon. Two Frenchmen, Pilatre d’Rozier and
the Marquis Francois d’Arlandes, flew their
way into history aboard the balloon launched
in Paris. The flight lasted about 25 minutes
and it landed approximately five miles form
the launch point.
57. How They Fly
• A balloon operates on the principle of buoyancy. Hot air is lighter, or
more buoyant, than cold air. The large container that holds this hot
air is called the envelope. There are strips of very strong material
along the vertical length of a balloon that attach to the envelope to
the basket. These are known as load tapes. Power for the balloon is
provided by a propane burner that quickly heats the air inside the
envelope. When the pilot pulls a chord, the liquid propane rushes
through a serious of vaporizing coils and is ignited at a jet by a pilot
flame in the burner. During accent, temperatures have been known
to reach 212 degrees Fahrenheit. Burners need to produce several
million BTU’s/hour. A BTU is a “British Thermal Unit”: the amount of
heat required to raise the temperature of one pound of water, one
degree Fahrenheit.
58. The Mathematics Of A Balloon’s Lifting
Power
• Typically, a (hydrogen) gas balloon will derive
about 60 lbs. of lift per 1,000 cu. Ft., whereas
as hot – air model will develop only 17-20 lb.
per cu. Ft. (at 100-120 degrees Celsius). Thus a
77,000 cu. Ft. balloon will lift: 77 x 17 = 1,309
lbs gross lift.
59. The Basket – A Balloon Pilot’s Cockpit
• A balloon pilot’s control system is the ascent and
descent power of the burner. There is a panel inside of
the hot air balloon that allows some of the hot air to
escape. It’s called a parachute and looks somewhat like
a conventional parachute only it fills a hole in the top
of the balloon known as a vent. The vent varies from 6
- 18 feet across. When the pilot wants to release some
of the hot air, a cord is pulled which draws the
parachute downward thus opening the vent hole.
When the cord is released, the parachute is pushed
back into the vent, closing it so the rest of the hot air is
not allowed to escape. The basket of a balloon is its
cockpit.
