LF Energy Webinar: Electrical Grid Modelling and Simulation Through PowSyBl -...DanBrown980551
Do you want to learn how to model and simulate an electrical network from scratch in under an hour?
Then welcome to this PowSyBl workshop, hosted by Rte, the French Transmission System Operator (TSO)!
During the webinar, you will discover the PowSyBl ecosystem as well as handle and study an electrical network through an interactive Python notebook.
PowSyBl is an open source project hosted by LF Energy, which offers a comprehensive set of features for electrical grid modelling and simulation. Among other advanced features, PowSyBl provides:
- A fully editable and extendable library for grid component modelling;
- Visualization tools to display your network;
- Grid simulation tools, such as power flows, security analyses (with or without remedial actions) and sensitivity analyses;
The framework is mostly written in Java, with a Python binding so that Python developers can access PowSyBl functionalities as well.
What you will learn during the webinar:
- For beginners: discover PowSyBl's functionalities through a quick general presentation and the notebook, without needing any expert coding skills;
- For advanced developers: master the skills to efficiently apply PowSyBl functionalities to your real-world scenarios.
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.

Slack (or Teams) Automation for Bonterra Impact Management (fka Social Soluti...Jeffrey Haguewood
Sidekick Solutions uses Bonterra Impact Management (fka Social Solutions Apricot) and automation solutions to integrate data for business workflows.
We believe integration and automation are essential to user experience and the promise of efficient work through technology. Automation is the critical ingredient to realizing that full vision. We develop integration products and services for Bonterra Case Management software to support the deployment of automations for a variety of use cases.
This video focuses on the notifications, alerts, and approval requests using Slack for Bonterra Impact Management. The solutions covered in this webinar can also be deployed for Microsoft Teams.
Interested in deploying notification automations for Bonterra Impact Management? Contact us at sales@sidekicksolutionsllc.com to discuss next steps.
Let's dive deeper into the world of ODC! Ricardo Alves (OutSystems) will join us to tell all about the new Data Fabric. After that, Sezen de Bruijn (OutSystems) will get into the details on how to best design a sturdy architecture within ODC.
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.

Collection Interface
• Defines fundamental methods
• int size();
• boolean isEmpty();
• boolean contains(Object element);
• boolean add(Object element); // Optional
• boolean remove(Object element); // Optional
• Iterator iterator();
• These methods are enough to define the basic behavior of a collection
• Provides an Iterator to step through the elements in the Collection

List Implementations
• ArrayList
• low cost random access
• high cost insert and delete
• array that resizes if need be
• LinkedList
• sequential access
• low cost insert and delete
• high cost random access
• Vector
• Similar to ArrayList, but thread-safe

ArrayList vs. LinkedList vs. Vector
From the hierarchy diagram, they all implement List interface. They are very
similar to use. Their main difference is their implementation which causes
different performance for different operations. ArrayList is implemented as a
resizable array. As more elements are added to ArrayList, its size is increased
dynamically. It's elements can be accessed directly by using the get and set
methods, since ArrayList is essentially an array. LinkedList is implemented as a
double linked list. Its performance on add and remove is better than Arraylist, but
worse on get and set methods. Vector is similar with ArrayList, but it is
synchronized. ArrayList is a better choice if your program is thread-safe. Vector
and ArrayList require space as more elements are added. Vector each time
doubles its array size, while ArrayList grow 50% of its size each time. LinkedList,
however, also implements Queue interface which adds more methods than
ArrayList and Vector, such as offer(), peek(), poll(), etc. Note: The default initial
capacity of an ArrayList is pretty small. It is a good habit to construct the ArrayList
with a higher initial capacity. This can avoid the resizing cost.

LinkedList
• Uses doubly linked list to store the elements. It provides a linked-list data
structure. It inherits the AbstractList class and implements List and Deque
interfaces
• Java LinkedList class can contain duplicate elements.
• Java LinkedList class maintains insertion order.
• Java LinkedList class is non synchronized.
• In Java LinkedList class, manipulation is fast because no shifting needs to be
occurred.
• Java LinkedList class can be used as list, stack or queue.
