Concrete cable trough is in service throughout the UK Network Rail infrastructure including West Coast Main Line Upgrade, Channel Tunnel Rail Link and Southern Power Upgrade projects. Concrete cable troughs have been installed for light rail and underground train systems at Glasgow, Newcastle, Sheffield, Birmingham, Manchester and Nottingham. Specialist and customised rectangular and trapezoidal concrete cable troughs can be produced to order - this includes concrete cable trough, duct and channel. The cable trough system is complemented by a complete range of concrete tees, transitions and curves specifically designed to complement concrete cable trough systems - all cable trough products are approved to Network Rail RT/E/PS/0013.
The concrete cable trough lids are designed to withstand an 11.5 tonne wheel loading thus allowing vehicle overrun - cable trough lids are available in steel chequer plate and concrete infill. All cable trough lids are galvanised to prevent corrosion, with the larger lids having substantial under-bracing to attain required strength. Please note lids with under-bracing will reduce the internal capacity of the cable trough. Concrete cable trough lids provide trackside protection to cable runs including fibre and radio cables.
There is approximately a 20% savings cost for using rolled threads instead of cut thread rods. Per ACI 318 Section D, there is no capacity difference between the two methods of manufacturing when used as anchor bolts set in concrete.
Get the right information about brass cable gland. Vatsalya Metal, Brass cable gland manufacturers and exporters gives some essential information about cable glands types and how to but it.
Flare Electricals range of A1/A2 Cable Glands are manufactured from high quality brass. These are used for unarmored cables, rubber or plastic sheathed cables. Larger sizes are made by sand casting technique while smaller sizes are made from extruded rods.

Isolation Procedures for Safe Working on Electrical Systems and Equipment by the JIB | solation Procedures for Safe Working on Electrical Systems and Equipment
This chart shows the safe isolation procedure that you should use when working on electrical systems and equipment.
You'll receive a printed copy of this from your Training Provider, but it's also here as a handy reference to keep electronically.
THE RULES OF SAFE ISOLATION ARE:
Obtain permission to start work (a Permit may be required in some situations)
Identify the source(s) of supply using an approved voltage indicator or test lamp
Prove that the approved voltage indicator or test lamp is functioning correctly
Isolate the supply(s)
Secure the isolation
Prove the system/equipment is DEAD using an approved voltage indicator or test lamp
Prove that the approved voltage indicator or test lamp is functioning correctly
Put up warning signs to tell other people that the electrical installation has been isolated
Once the system/equipment is proved DEAD, work can begin

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.
"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.
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.
Neuro-symbolic is not enough, we need neuro-*semantic*
