Virtual Reality (VR) in engineering is often associated with applications in product evaluation in terms of mountability, maintainability, ergonomics or in industrial engineering. Nevertheless, several VR applications have been established in recent years that deal with manufacturing processes.
The Virtual Dimension Center (VDC) Fellbach points out the status quo, tools and applications of digital techniques for styling and design applications.
Almost since the advent of commercially available Virtual Reality (VR) systems in the early 1990s, attempts have been made to harness this technology for design applications as well. While initially focusing on establishing realistic, sometimes photorealistic visualizations of digital prototypes as part of the development feedback loop, it was quickly attempted to use VR not only as a source of output but as an input medium in the design process.
Design usually means design or shaping. Design is based on people and their diverse needs. These needs range from physical and psychological needs to the requirements of the human mind to the physical environment. Design does not just follow self-imposed rules and intentions, but must deal primarily with the interests of those groups or people who should be the users of the design. Thereby design and its drafts are above all purpose-oriented. In design theory, the term functionality was coined for that. In the traditional view, the beginning of a development process is the analysis of the found and the requirements of an innovative concept. The analysis is followed by the concretization of a concept. The concept of the designer already defines initial ideas for the nature of a system or object.
Virtual engineering methods with their objective to establish fast development cycles as an active process element, to early feedback on results, the emphasis on early development phases, the possibility of alternative pursuit and the specification decision can support creative tasks. Immediate access to digital 3D models via multimodal spatial input systems and multi-modal 3D output make VR an efficient tool, especially in design reviews.
The VDC white paper provides an overview of the status quo, tools, and applications of virtual reality in design tasks.
The Virtual Dimension Center (VDC) Fellbach has published the whitepaper "Virtual Techniques in Factory Planning". It presents applications, technologies and practical examples of Virtual and Augmented Reality (VR, AR) in factory planning. The conclusion is clear: the fields of application and potential benefits are numerous. Virtual hedging techniques help to reduce consequential costs.
The whitepaper "Collaborative Virtual Engineering" provides an overview of various cooperative VR systems, their benefits and application scenarios. Basically, there are the following four technical possibilities for using Virtual and Augmented Reality for collaborative engineering: planning tables, large displays, collaborative augmented reality and distributed virtual environments. The cooperation approaches that can be achieved are fundamentally different. Equally diverse are possible application scenarios. The systems to be selected are therefore well suited to the intended use. The variety of features require careful selection and testing. Their involvement in development / service / training / marketing processes has to be planned.
This is a release note for midas NFX 2015, finite element analysis software focusing on accuracy and flexibility.
New features and improvement are presented in detail. Multi-media resources, such as video demo and online trying module, are included. For more information about midas NFX and this release, please visit: www.midasNFX.com
Modeling and Simulation of Virtual Prototype of the forming Machine based on ...IJRES Journal
The virtual prototype technology was applied to mechanism designing. The modeling and dynamic of forming machine was proposed by using SolidWorksand ADAMS software. The advantage of the technology is that the product characteristics can be calculated in the design stage, and the feasible study and design of the forming machine can be completed in a virtual environment .As a result, the design quality and efficiency of the forming machine are improved, and its developing and manufacturingperiod is reduced correspondingly.
The Virtual Dimension Center (VDC) provides an overview of the fields of application and trends of virtual technologies in automotive engineering. These are used in development, production, marketing, training and service, making physical prototypes increasingly redundant. In future, manufacturers will rely even more on these methods and tools.

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.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

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.

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!

processes of coating
The aim of the simulation is to achieve the
desired properties (such as layer thickness) in
the case of an optimal varnishing process
(such as process reliability, process speed, use
of resources)
VR applications for varnishing simulation aim
at the analysis of the varnishing process itself,
the result and the training of the varnishing
process

Summary
Virtual reality techniques are already used
today for the analysis and design of
numerous manufacturing processes
In some application areas, such as
casting, the use of VR is well-developed
Other topics: general need to catch up

Summary

Other topics: general need to catch up
Research has shown that identified VR
applications do not even represent half of
all possible manufacturing processes
At the same time, it became apparent
that in a specific case often only a small
part of the possible applicable VR
technologies is used. Often it would be
worth it to think outside the box
