Spectral data has arrived with the new iccMAX specification. This will lead to significant improvements in multi-ink printing where color separation will be based on spectral matching. It also provides a framework for combining scientific and studio photography for image archiving. Multispectral photography bridges hyperspectral imaging, used in conservation science, and RGB imaging, used in the studio. Two approaches will be described. The first is dual-RGB where an RGB camera and two colored filters (or lights) combine to form a five-channel multispectral camera. The second is a conventional system consisting of a monochrome camera and filter wheel. This new seven-filter multispectral system was designed with three quality criteria: high color accuracy, moderate spectral accuracy, and low color transformation noise.
Multispectral imaging is a digital imaging technique that adds depth to understanding cultural heritage collections. It is a unique technology combining components from cross-disciplinary fields, thus requiring diverse standards, practices, and workflows. This poses challenges when integrating this system into a digitization lab with pre-established methods of operation, but is nonetheless feasible, as demonstrated by the collaboration between the Preservation Research and Testing Division of the Library of Congress (USA) and the digitization labs of The John Rylands Library, University of Manchester (UK).

Air monitoring sensors and advanced analytics in exposure assessmentDrew Hill
https://doi.org/10.6084/m9.figshare.12354866.v2
We are in the middle of a movement in environmental sensors that is taking the world by storm— Californian governments and public health practitioners, in particular, are leading the nation in exploring and implementing environmental sensors in the production of highly granular, realtime air quality information. As this movement matures, we are seeing improved understanding of ambient exposures and insights that are truly actionable — for example informing community emissions reduction plans under the recent Assembly Bill 617. This innovation in air quality sensor science can be leveraged to improve measurements in the industrial and occupational spaces. This movement has also lead to innovations in analysis methods that facilitate exposure insights not feasible with standard filter, adsorbent, and general integrated samples. This presentation discusses recent advancements in these spaces and offer brief examples of their implementation and potential applicability toward the industrial and occupational hygiene spaces.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

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).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms. He is known for his dynamic presentations in CI/CD and application security integrated in software delivery lifecycle.
Gopinath Rebala
Gopinath Rebala is the CTO of OpsMx, where he has overall responsibility for the machine learning and data processing architectures for Secure Software Delivery. Gopi also has a strong connection with our customers, leading design and architecture for strategic implementations. Gopi is a frequent speaker and well-known leader in continuous delivery and integrating security into software delivery.
Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
