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.

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.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

3. Project Objectives: Understand rack and pinion gear mechanism. Come up with an innovative solution for building that design as a standard one. Determine the various forces that are meshed within gears. In context of all the gear parameters referring to right selection of material for rack and as well as for pinion. www.postointernational.tk
6. Two rack and pinion gears are used to slide gate on rail as load will uniformly be distributed mounted on its ends.www.postointernational.tk
7. Rack and Pinion Gear Design Rack & Pinion Gear A rack and pinion gears system is composed of two gears. The normal round gear is the pinion gear and the straight or flat gear is the rack. The rack has teeth cut into it and they mesh with the teeth of the pinion gear. . Pinion Rack
9. Rack and Pinion Gear Design Rack & Pinion Gear contd. Rack and pinion gears provide a greater feedback and steering sensation. A well designed mechanism such as the rack and pinion gears save effort and time. .
10. Rack and Pinion Gear Design Rack & Pinion Gear contd. The rack and pinion is used to convert between rotary and linear motion. Rack and pinion can convert from rotary to linear of from linear to rotary. The diameter of the gear determines the speed that the rack moves as the pinion turns. Rack and pinions are commonly used in the steering system of cars to convert the rotary motion of the steering wheel to the side to side motion in the wheels. .
11. Rack and Pinion Gear Design Designing Rack & Pinion Gear. Identify a Need Conceptual Design Preliminary Design Final Design Manufacture Sales & Delivery Engineering Design . Designing Rack & Pinion Gear.
12. Rack & Pinion Rack & PinionTwo types Rack and pinion gears are available in two variations Straight teethorSpur Type Helical teethor Helical Type www.postointernational.tk
14. Preliminary Design For spur gear design, pinion and rack both have straight teeth or spur geometry of teeth. So for we will first consider the design of pinion as spur gear. www.postointernational.tk
15. Spur Gear Design and Selection Objectives • Calculate forces on teeth of spur gears, including impact forces associated with velocity and clearances. • Determine allowable force on gear teeth, including the factors necessary due to angle of involute of tooth shape and materials selected for gears. • Understand how lubrication can cushion the impact on gearing systems and cool them. www.postointernational.tk
17. Forces on Spur Gear Teeth Ft = Transmitted force Fn = Normal force. Fr = Resultant force θ = pressure angle Fn = Ft tan θ Fr = Ft/Cos θ www.postointernational.tk
18. Forces on Spur Gear Teeth Power, P; = Torque, Combining the above we can write: www.postointernational.tk
19. Surface Speed Surface speed (Vm) is often referred to as pitch-line speed: www.postointernational.tk
20. Strength of Gear Teeth Lewis form factor method Lewis equation Fs = Allowable dynamic bending force (lb) Sn = Allowable stress. Use endurance limit and account for the fillet as the stress concentration factor b = Face width (in.) Y = Lewis form factor (From Table) Pd = Diametral pitch www.postointernational.tk
22. Classes of Gears • Transmitted load depends on the accuracy of the gears • Gear Manufacture – Casting – Machining • Forming • Hobbing • Shaping and Planing – Forming www.postointernational.tk
23. Force Transmitted Transmitted load depends on the accuracy of the gears. A dynamic load factor is added to take care of this. • Ft = Transmitted force • Fd = Dynamic force • Commercial www.postointernational.tk
24. Classes of Gears Carefully cut Precision Hobbed or shaved www.postointernational.tk
26. Design Methods • Strength of gear tooth should be greater than the dynamic force; Fs ≥ Fd • You should also include the factor of safety, Nsf. www.postointernational.tk
28. Face width of Gears Relation between the width of gears and the diametral pitch. www.postointernational.tk
29. Dynamic Beam Strength of the Gear To increase the dynamic beam strength of the gear – Increase tooth size by decreasing the diametral pitch – Increase face width upto the pitch diameter of the pinion – Select material of greater endurance limit – Machine tooth profiles more precisely – Use proper lubricant and reduce contamination www.postointernational.tk
30. Buckingham Method of Gear Design • It offers greater flexibility. • Expected error is based on different-pitch teeth. • More conservative design. www.postointernational.tk
31. Wear strength (Buckingham) Fw = tooth wear strength. Dp = diametral pitch of pinion. Dg = diametral pitch of gear. b = face width. Kg = load stress factor. www.postointernational.tk
33. Conclusion So far we have been able to calculate the design of pinion only in the next phase of project we will be designing the rack. Passed on fundamental knowledge of rack and pinion gear mechanism and it design procedure & finally selecting the right material for it. www.postointernational.tk
