- The Generic Methodology for Verification, Validation and Acceptance (GM-VV) is intended to provide a common generic framework for making formal and well balanced acceptance decisions on a specific usage of models, simulations and data. GM-VV will offer the international M&S community with a Verification, Validation (VV) and Acceptance methodology that consistently embraces a wide variety of M&S technologies and application domains. The GM-VV builds upon a triad of three pillars; the products, the organization and process pillar. At the centre of the products pillar stands the GM-VV data information model. The GM-VV data information model is the structural model for the GM-VV project memory approach. This project memory not only stores the GM-VV core products but also serve as the data and information source for generating these products. In this paper the formal specification of the GM-VV data information model and its underlying principles, concepts and methods are presented. The paper shows how this model is used in the GM-VV project memory approach to produce the core GM-VV products being: the acceptance plan, the verification & validation plan, the evidence, the verification &validation report, and the acceptance report.

- Fiducial and total W± and Z boson cross sections, their ratios and the ratio of top-antitop-quark pair and W-boson fiducial cross sections are measured in proton–proton collisions at a centre-of-mass energy of s=13.6 TeV, corresponding to an integrated luminosity of 29 fb−1 of data collected in 2022 by the ATLAS experiment at the Large Hadron Collider. The measured fiducial cross-section values for W+→ℓ+ν, W−→ℓ−ν¯, and Z→ℓ+ℓ− (ℓ=e or μ) boson productions are 4250±150 pb, 3310±120 pb, and 744±20 pb, respectively, where the uncertainty is the total uncertainty, including that arising from the luminosity of about 2.2%. The measurements are in agreement with Standard-Model predictions calculated at next-to-next-to-leading-order in αs, next-to-next-to-leading logarithmic accuracy and next-to-leading-order electroweak accuracy.

Conference paper (peer-reviewed)abstract
- Area coverage and robot navigation are two important research fields within robotics. However, their intersection has received limited attention. In coverage problems, perfect navigation is often assumed, and in robot navigation, the focus is often to minimize the localization error while traveling a given trajectory.The need for integration of the two becomes clear in environments with very sparse features or landmarks, for example when an Autonomous Underwater Vehicle (AUV) is to search the seafloor for dangerous objects, such as mines.The potential consequences of missing a mine due to navigation errors can be catastrophic.If the localization error is large, a trajectory that was designed to guarantee complete coverage might have missed significant parts of the area. Thus, the coverage trajectory must be planned with the navigation performance in mind, applying a combination of using large enough planned overlaps of sensor footprints to account for the position uncertainty, and reducing this uncertainty by re-visiting the known sparse landmarks.In this paper we compute trajectories that guarantee coverage for a given area under assumptions on worst case localization error growth.We further more compute upper bounds for how large areas can be covered using common coverage patterns and a single landmark, which leads to bounds on how sparse the landmarks can be in the regions to be covered.

Conference paper (peer-reviewed)abstract
- Both as researchers and professionals in the field of disability we make attempts to understand people’s life situations in different respects. We present research results in various media, where everyone can read about the life circumstances of a particular group or persons, and as professionals we intend to interpret people’s life situations for the purpose of rehabilitation plans, teaching activities, etc. The question we will address concerns the trustworthiness in understanding another person’s life. For instance, in the tradition of life-world phenomenological research, how is it possible to understand another person’s world? And, to make it even more difficult; how is it possible to understand the world of a person with functional or activity limitations, in this case a person who is blind? Within a life-world approach, this question is imperative. What are the possibilities, but also difficulties or limitations, in trying to understand a blind and a sighted person’s world respectively? From interpretative standpoint it is of great importance to find usable concepts in the ‘research communication arena’, but also to penetrate the perceptual ground for the language used. To answer these questions qualitative research is the preferred strategy to approach O&M practice, for instance when introducing new environments and orientation activities. In the presentation we will address these questions from the perspective of the researcher and the professional, but also from the perspective of our own experiences of blindness and normal vision. Here we will use our own experiences in trying to understand the world of blindness and sightness respectively.
