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.
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.
PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.
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.

2. ACTIVITY TESTING APPLICATIONS
ULTRA LOW SULFUR DIESEL HYDROTREATING (HDS)
The majority of the catalysts we test belong to the ULSD category, where the investment
and operational risks associated with regeneration and rejuvenation of the catalyst justify an
HDS activity test before the catalyst is reused. Activity testing is an essential and
dependable quality control tool, allowing the transfer and reuse of your catalyst batch within
the corporate catalyst pool. Eurecat tracks the activity values for various lots in catalyst
pools we manage for several refining majors, allowing the customer to carefully manage
when and where each lot is applied with minimum risk exposure.
Our standard MTU test protocol measures catalyst performance at 3 different levels of
severity utilizing straight-run gasoil (1.2 wt% S) at the following conditions:
WABT: 640 / 650 / 660 °F LHSV: 2 h-1
pressure: 580 psi H2/oil: 300
EURECAT’s extensive database on activity testing contains a wealth of process and
catalyst knowledge. Shown below is an example of a study carried out by EURECAT to
assess the effects of different contaminants on the activity of REACT™ treated KF-757.
HORSE TRADING
If you don’t have a requirement to reuse
your catalyst within your own refinery,
having it activity tested by EURECAT
will open the door to selling it to an
affiliated refinery or to a third party.
EURECAT’s catalyst purchase and
resale network is shared between our
