Towards data exchange formats for learning experiences in manufacturing workplaces

Manufacturing industries are currently transforming, most notably through the introduction of advanced machinery and increasing degrees of au- tomation. This has caused a shift in skills required, calling for a skills gap to be filled. Learning technology needs to embrace this change and with this contri- bution, we propose a process model for learning by experience to understand and explain learning under these changed conditions. To put this process into practice, we propose two interchange formats for capturing, sharing, and re- enacting pervasive learning activities and for describing workplaces with in- volved things, persons, places, devices, apps, and their set-up

Enabling Image Recognition on Constrained Devices Using Neural Network Pruning and a CycleGAN

Smart cameras are increasingly used in surveillance solutions in public spaces. Contemporary computer vision applications can be used to recognize events that require intervention by emergency services. Smart cameras can be mounted in locations where citizens feel particularly unsafe, e.g., pathways and underpasses with a history of incidents. One promising approach for smart cameras is edge AI, i.e., deploying AI technology on IoT devices. However, implementing resource-demanding technology such as image recognition using deep neural networks (DNN) on constrained devices is a substantial challenge. In this paper, we explore two approaches to reduce the need for compute in contemporary image recognition in an underpass. First, we showcase successful neural network pruning, i.e., we retain comparable classification accuracy with only 1.1% of the neurons remaining from the state-of-the-art DNN architecture. Second, we demonstrate how a CycleGAN can be used to transform out-of-distribution images to the operational design domain. We posit that both pruning and CycleGANs are promising enablers for efficient edge AI in smart cameras

Patch Testing with a Textile Dye Mix in a Baseline Series in Two Countries

Disperse dyes are the most common contact sensitizers among textile dyes. The main aim of this study was to investigate the outcome of patch testing with a textile dye mix 6.6%. A total of 2,049 patients from Sweden and 497 from Belgium were tested with the mix, consisting of Disperse (D) Blue 35, D Yellow 3, D Orange 1 and 3, D Red 1 and 17, 1.0% each, and D Blue 106 and D Blue 124, 0.3% each. Of the total number, 65 patients, 2.6%, tested positively to the mix, 4.2% of the Belgian patients and 2.1% of the Swedish patients. Patch testing with the mix 6.6% revealed significantly more patients with contact allergy compared with testing with a previous mix 3.2% (p<0.01). Contact allergy to the mix was significantly more common in the Belgian than in the Swedish patients

Total Synthesis of Phorbazole B

Phorbazoles are polychlorinated heterocyclic secondary metabolites isolated from a marine sponge and several of these natural products have shown inhibitory activity against cancer cells. In this work, a synthesis of the trichlorinated phorbazole B using late stage electrophilic chlorination was developed. The synthesis relied on the use of an oxazole precursor, which was protected with an iodine in the reactive 4-position, followed by complete chlorination of all pyrrole positions. Attempts to prepare phorbazole A and C, which contain a 3,4-dichlorinated pyrrole, were unsuccessful as the desired chlorination pattern on the pyrrole could not be obtained. The identities of the dichlorinated intermediates and products were determined using NMR techniques including NOESY/ROESY, 1,1-ADEQUATE and high-resolution CLIP-HSQMBC

Brandteknisk riskvärdering av äldreboendet Häradsgården

This report is based on a fire safety evaluation of Häradsgårdens retirement home and presents the method during the work and the result. The report is a part of the Fire Safety Engineer program at Lund University and written by students. The main focus during the evaluation was to look at the personal safety during a fire in the building and just a small concern was taken to economic aspects. The goal of the report is to make sure that all personnel and residents are able to evacuate, according to the prepared evacuation plan for the home, in a safe environment. The current fire protection of the building was evaluated. When the goal of safe evacuation was not reached, measures to improve the ability to evacuate were examined. The computer programs FDS, CFAST and ERM were used together with hand calculations and qualitative assessments when performing the fire safety evaluation

Towards PLEs through Widget Spaces in Moodle

Bringing flexibility and extensibility into Learning Management Systems is crucial because it gives teachers and students a free choice of technologies and educational materials they want to use for their courses. This paper presents a solution by enabling widgets (OpenSocial apps) within Mood le. Our first Moodle plugin allows teachers to freely choose a set of tools they want to use in their courses, although students cannot change widgets proposed by teachers. Additionally, the plugin enables the flexible interaction interfaces inside Mood le and improves the interoperability of Mood le with other Web platforms. The environment was evaluated with students within several courses. Even though the environment was perceived as useful by students, they lacked their own personalization. The second Mood le plugin described tackles this problem
