Proceedings of the 29th EG-ICE International Workshop on Intelligent Computing in Engineering

This publication is the Proceedings of the 29th EG-ICE International Workshop on Intelligent Computing in Engineering from July 6-8, 2022. The EG-ICE International Workshop on Intelligent Computing in Engineering brings together international experts working on the interface between advanced computing and modern engineering challenges. Many engineering tasks require open-world resolution of challenges such as supporting multi-actor collaboration, coping with approximate models, providing effective engineer-computer interaction, search in multi-dimensional solution spaces, accommodating uncertainty, including specialist domain knowledge, performing sensor-data interpretation and dealing with incomplete knowledge. While results from computer science provide much initial support for resolution, adaptation is unavoidable and most importantly, feedback from addressing engineering challenges drives fundamental computer-science research. Competence and knowledge transfer goes both ways. &nbsp

CityGML goes mobile: application of large 3D CityGML models on smartphones

CityGML, a semantic information model for digital/virtual city models has become quite popular in various scenarios. While the data format is still actively under development, it is already supported by different software solutions, especially GIS-based desktop applications. Mobile systems on the other hand are still neglected, even though the georeferenced objects of CityGML have many application fields, for example, in the currently popular area of location-based Augmented Reality. In this paper we present an independent multi-platform CityGML viewer, its architecture and specific implementation techniques that we use to realize and optimize the process of visualizing CityGML data for use in Augmented Reality. The main focus lies in improving the implementation on mobile devices, such as smartphones, and assessing its usability and performance in comparison to web-based approaches. Due to the constrained hardware resources of smartphones, it is a particular challenge to handle complex 3D objects and large virtual worlds as provided by CityGML, not only in terms of memory and storage space, but also with respect to mobile processing units and display sizes

A role for B-12 in inflammatory bowel disease patients with suppurative dermatoses? An experience with high dose vitamin B-12 therapy

Background: Inflammatory dermatoses in conjunction with inflammatory bowel disease (IBD) comprise a diverse range of disorders. Some but not all of these respond to conventional treatments for the underlying IBD, such as immunomodulating or antibiotic treatments. We describe our experience with high dose vitamin B, where conventional therapies have failed. Case reports: The first case had pouchitis complicated by perianal abscesses and a recto-vaginal fistula. The second case had biopsy proven hidradenitis suppurativa affecting the perianal, inguinal and pubic skin. High dose vitamin B appeared to be the major factor in preventing the recurrence of suppuration in both patients. Neither patient had vitamin B deficiency. Open label experience: high dose vitamin B treatment of a further 10 consecutive IBD patients with dermatoses was thought to provide benefit to six of them, but did not appear useful in four patients with perianal Crohn's disease with fistulae as the only manifestation of cutaneous disease. Conclusions: There appears to be a subset of IBD patients with perianal and more distant inflammatory dermatoses, who benefit from high dose vitamin B treatment. Clinical trials in IBD patients with biopsy-characterised suppurative dermatoses will be required in order to properly define the role of this safe and economical therapy
