The introduction of complex regulations such as the EU's AI Act places new, high demands on precision and efficiency in regulatory processes. At the same time, analyses from bodies including the "Swedish Regulation Council" (Regelrådet) and the OECD show that up to 60% of current Swedish impact assessments do not meet the set requirements, often due to resource constraints and complexity. This deficiency constitutes an obstacle to both responsible innovation and predictable regulatory compliance, especially within fast-moving technology areas like artificial intelligence. The need for more reliable, objective, and time-efficient methods is acute.

Pioneering AI Support for impact assessment

In response to these challenges, the RegTek project addresses the need for modernized regulatory tools. RISE is leading a strategic pilot study to evaluate an advanced language model based on Retrieval-Augmented Generation (RAG), developed by the Swedish National Financial Management Authority (ESV). The RAG technology is particularly promising as it combines the capabilities of large language models with the ability to dynamically retrieve and integrate information from specified, reliable sources. This enables the generation of impact analyses that are both contextually relevant and fact-based, which is crucial for regulatory application.

RAG performance measurement and trustworthyness

RegTek is conducting a pilot study where RISE evaluates a RAG-based language model developed by the Swedish National Financial Management Authority (ESV). The evaluation includes performance measurements and an investigation into how standards and metrological methods can be applied to measure precision and reliability.

Improved compliance, increased trust, and strengthened national AI capability

The RegTek project aims to deliver measurable improvements and strategic advantages:

• Streamlined regulatory processes: Potential for significantly faster and more resource-efficient impact assessments.
• Validated reliability: An objectively evaluated method to measure and ensure the accuracy of AI-generated documentation, strengthening trust among regulators and decision-makers.
• Facilitated AI Act compliance: Improved tools that support organizations' ability to meet the requirements of the EU's AI Act and other complex regulations.
• National competence enhancement: The project strengthens Sweden's collective capability in AI testing, validation, and responsible implementation of AI in the public sector, through the work of RISE and ESV.
• Knowledge dissemination via open source: Developed evaluation methods and key results are planned to be published as open source, promoting transparency and broader benefit.

Through RegTek, RISE contributes to building a foundation for the safe, effective, and reliable use of AI in support of future regulations.

This course provides you with an up-to-date and practical overview of how water metering works today—and what you need to be aware of in your work.

During the course, we will review different types of water meters, their installation and operation, as well as the principles behind volume and flow measurement. We will also take a closer look at regulations and requirements related to type approval, calibration, and market surveillance in accordance with SWEDAC, as well as current topics such as NIS2, data classification, and the Drinking Water Directive.

Through concrete examples and real-world case scenarios, we will discuss common challenges, measurement uncertainties, and legal aspects—all to give you a clearer overall understanding and practical insights that you can apply directly in your operations.

Access to accurate time is a prerequisite for modern society to function. We take it for granted that the clock in connected devices like computers or mobile phones is correct, but we may not often think about where that time comes from.

Today, the protocols NTP and NTS are commonly used for clock synchronization over routed computer networks such as the internet. NTS provides secure, authenticated, and encrypted data transmission, which makes so-called "man-in-the-middle" attacks more difficult—where someone can undetectedly send false data under a fake sender identity. This is a known vulnerability in NTP. Both protocols are open, and anyone can set up a server without any requirements on the quality of the time signal.

Varying Quality of NTP Servers

A survey conducted by RISE in 2024 showed that 75 percent of all publicly available NTP servers deviated less than 50 ms from UTC. These were distributed around a mean offset of 7 ms from UTC, with a standard deviation of 13 ms. The remaining 25 percent of NTP servers deviated significantly—up to several seconds—and showed no clear statistical distribution. There is therefore reason to carefully consider where you get your time from.

What Affects Accuracy?

The accuracy of time synchronization is affected by several factors. The network distance to the server matters, as the risk of asymmetric signal paths increases due to routing and interference. The quality of the server’s own time source can also vary. With a good connection to a high-quality time server, you can expect synchronization offsets from UTC in the range of just a few milliseconds.

Swedish Time Scale UTC(SP) via NTS or NTP

With RISE’s NTS servers, users can be assured that the time is delivered by RISE and directly linked to the official Swedish time scale UTC(SP). RISE also provides a classic NTP service with the same level of time accuracy.

We also offer services to monitor customers’ NTP/NTS servers in terms of availability and accuracy relative to UTC(SP). For customers who require even more precise time synchronization over networks, RISE can offer peer-to-peer solutions using, for example, Precision Time Protocol (PTP) or White Rabbit (WR).

This time, only a smaller number, namely eight, waterproofing systems have been investigated.

Summery of the results

• Two structures showed no leaks at the end of the test, which corresponds to 25%.
• Six structures showed leaks at various locations at the end of the test, which corresponds to 75%. In this investigation, the majority of leaks were located at floor-wall angles.
• Leaks were noted at penetrations of both large and small drain pipes for two of the structures examined.
• Only one leak was observed at an internal corner.
• It is gratifying that none of the waterproofing systems examined showed leaks at floor drains, and no leaks were so extensive that they could be classified as total damage.

The project is carried out using a functional test, which means that the water tightness of the waterproofing membrane, penetrations and joints are examined in the waterproofing construction.

Summery of results from the functional tests 2010–2025

A total of 91 tests have been carried out during the period 2010 to 2025, i.e. over 15 years.

Of these, 29 (32%) have been positive, i.e. no leaks have been observed at the end of the test.

Negative results, leaks in some form, have been obtained in 62 (68%) of the tests carried out.

The conclusion that can be drawn from the historical review is that the results have improved over time. Overall, however, it must be concluded that the industry should be able to perform better.

The safety margin is obviously quite low or, for some, waterproofing systems completely non-existent.

Therefore, we believe that there is every reason to continue with this type of investigation in order to persuade the industry to further develop its waterproofing structures.
