CUF vs PR
This document discusses the difference between CUF (Capacity Utilization Factor) and PR (Performance Ratio) as metrics for evaluating the performance of solar PV systems. CUF compares actual output to theoretical maximum output without considering external factors like weather, while PR takes these factors into account. PR is considered a better metric as it provides insights into how external conditions impact performance and allows for quality control. The benefits of PR over CUF for developers, investors and EPCs are that PR enables comparison of plant output to what could be achieved given site conditions, early identification of performance issues, and limits liability to only factors within direct control.
REACH Solar Consultants - Presentation at Intersolar India 2013 | Learnings f...
The document discusses optimization of PV plant design based on analysis of performance data from 50 PV plants in India totaling 2GW of installations. It finds that CUF (capacity utilization factor) varies significantly between plants from 12.2% to 21.3% despite similar conditions, and that top performing plants have a CUF 6% higher than average. Further analysis shows performance is impacted not just by panels and inverters but also factors like civil works, string/combiner boxes, transformers, and mounting structures. The document advocates taking a holistic design approach and using performance ratio in addition to CUF for improved plant monitoring and optimization.

Using advanced PV and BoS modeling and algorithms to optimize the performance of large scale utility applicationsShort Commercial presentation_ROW.pptx
SolarEdge provides a commercial solar solution that offers four key benefits over traditional inverters: increased energy yield, lower operations and maintenance costs, enhanced safety, and more flexible design. Their solution utilizes power optimizers at the module level and monitoring software to maximize energy production, reduce costs over the system lifetime, and improve safety during installation and maintenance. While their inverters have a slightly higher upfront cost, SolarEdge's end-to-end solution offsets this with reduced balance of system costs, lower maintenance expenses, and increased energy production over time.

HYPERSIM Relay Protection Webinar
Challenges in Protection Relay Testing for Tomorrow’s Power Grid
Very many challenges related to protection relay testing are met today in the field and in the research industry.
There are often new and more complex applications such as wind turbines, very fast switching power electronics, photovoltaic cells and the battery and electric vehicle technologies. This implies among other things new converter topologies and smart grid considerations. These systems cannot be protected the same way as what was already being done, so this increases the complexity of the algorithms used.
Real-time simulation is a novel approach to design and test protection relay algorithms.
Energy efficiency in data processing centres
A real example on content marketing I did about Energy efficiency in data processing centres for a company I worked with.
Thesis
Neural network modeling and control of data centers is presented. Data centers consume significant and increasing amounts of energy. A neural network model is developed and trained using steady state and transient data from a physical data center setup to map temperature outputs. The neural network accurately models temperatures with 95% accuracy. A neural network controller is then designed using the inverse model to stabilize temperatures according to reference values in response to varying workloads and power consumption. The controller successfully regulates temperatures in real-time simulation. Future work includes implementing the control on an actual system and expanding the control parameters.

Epistemic Interaction - tuning interfaces to provide information for AI support
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.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Climate Impact of Software Testing at Nordic Testing Days
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.
zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex Proofs
This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).
