This document summarizes a presentation on the impact of water on road degradation. It discusses a research project studying water movement in road structures and presents field observations from moisture monitoring programs. Specifically, it shows how moisture levels varied with depth and temperature over time. Charts are also shown comparing measured stiffness values from road tests to gravimetric moisture content readings. Finally, it describes an instrumented test section and procedure used to study the effects of water on measured responses like pressure, strain and deflection.

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.

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.
The Art of the Pitch: WordPress Relationships and SalesLaura Byrne
Clients don’t know what they don’t know. What web solutions are right for them? How does WordPress come into the picture? How do you make sure you understand scope and timeline? What do you do if sometime changes?
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.

16. Conclusions
• Water influences the structural behaviour of pavements.
• A state of the art text book: Water in road structures –
movement, drainage & effects has recently been published.
• More knowledge need to be established regarding how water
affects the pavement structure.
• Water influence on pavement response and performance can be
studies in field monitoring programs, lab experiments as well is
full scale testing.
• We need to take advantage of this to build up the knowledge of
water impact on pavement structures.
