Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

All these questions and more will be explored as we talk about matching clients’ needs with what your agency offers without pulling teeth or pulling your hair out. Practical tips, and strategies for successful relationship building that leads to closing the deal.
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.
Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!
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.

3. CHALLENGES FOR BATTERIES–
OPPORTUNITY FOR ULTRACAPACITORS
▶ Low charge / discharge rate (not quick enough for frequency
regulation in grids, slow charge of EV battery)
▶ Safety concerns (fire hazard)
▶ Short lifetime (expensive to change)
▶ Low and high temperatures intolerance
▶ Low efficiency (heat generation requires expensive thermal
management systems)

4. BATTERY vs ULTRACAPACITOR
Ultracapacitors are all about power, unlimited cycling, safety and predictable life.
Ultracapacitors are less expensive than batteries for frequent cycling applications.
PARAMETER BATTERY ULTRACAPACITOR
Energy Density >100Wh/kg <10Wh/kg
Power Density 1kW/kg 10kW/kg

Death Sudden Predictable
Principle Electrochemical Electrostatic
Cost 0.07 - 0.2 $/kWh/cycle $0.006 $/ kWh /cycle

5. ULTRACAPACITOR PRINCIPLE AND BASIC DESIGN
Ultracapacitor (UC) comprises two
electrodes soaked in electrolyte. UC stores
energy due to charge separation in the
electric double layer of about 1 nm thick
that forms at the electrode-electrolyte
interface when the potential is applied.
UC electrodes are made of nano-structured
carbon applied on aluminum foil as a
current collector. The electrodes are
interleaved with an insulating porous film,
impregnated with electrolyte and sealed in
a cylindrical or prismatic case.

ENERGY
Practically no difference in
energy density among
ultracapacitor
manufacturers. Lots of
hype around graphene, but
no actual applications in
energy storage.
9. ▶ Low ESR results in high power density: P ~ 1/R
(hence, less UC mass lower cost)
▶ Low ESR results in small voltage drop: ΔU ~ R
(since P and E ~ U2, less UC cells can provide the power
and energy needed lower cost)
▶ Low ESR results in low heat generation: Q ~ R
(hence, no active cooling is needed safety and low cost)
WHY LOW INNER RESISTANCE (ESR) IS OUR MANTRA?
9
10. R1+R2 ~ 0.01
R3 ~ 0.05
Thus: R4+R5 ~ 0.64
R4 “in-pore resistance” ~ 0.5
ULTRACAPACITOR (UC) resistivity (in Ω.cm2)
Total ~ 0.7
Though: R5 ~ 0.14
UC resistance is mostly due to low
electrolyte mobility in nanopores
MAJOR CONTRIBUTORS TO INNER RESISTANCE

mobility can be selected for
negative electrode, and that with
highest anion mobility can be
selected for positive electrode

- 2 times more energy under high load;
- high power density that can not be
reached by other ultracapacitors.

PARALLEL HYBRID SOLUTION
OUR APPROACH: electrode level hybridization - both
positive and negative electrodes comprise Li-ion and
activated carbon components with thoroughly matched
potential ranges: “parallel hybrid” //LIC, patent pending
17
18. PARALLEL HYBRID: SIMPLE MODEL
Nanoporous carbon particles loosen oxide particles spatially
while connecting them electrically.
This results in:
• oxide particles become more accessible to electrolyte,
and nanoporous carbon provides a reservoir of
electrolyte;
• fast discharge of nanoporous carbon particles is then
accompanied and supported by discharging the
intercalated oxide particles.
General result: large energy density along with low inner
resistance and high power density.

22. CONCLUSIONS
1. The ultracapacitor power output and efficiency are due to its low internal resistance, which in
its turn is mostly determined by the electrolyte mobility in carbon electrode nanopores.
2. A new approach with both positive and negative electrodes being hybridized (//LIC) gives a
chance to increase the ultracapacitor energy density up to 30-40 Wh/kg while maintaining the
power output of 3-5 kW/kg at the efficiency above 80%.
3. Ultracapacitors are most efficient if the high power pulses of short duration (from fractions of a
second to ca. 20 seconds) are needed, while longer pulses (from 20 s to 10 min) can be best
covered by //LIC devices.
