The paper addresses computational design as a key technological asset in the development of the smart city. In particular, the research targets context-aware adaptation to usage requirements at urban fragment level. Indeed, cities' policy makers have to take into account many factors in a development policy, such as situational, technical or human-related factors as well as anticipating future usages. Moreover, nowadays, cities are key resources to answer growing humanitarian needs in terms of sheltering and camps. Indeed these situations are increasing due to different factors related to the nature, climate change or human activities. Resilience is therefore essential at the levels of districts, cities and territories. In Luxembourg, a public program aims to develop three container villages for refugees. The objective of this work is to help policy makers and humanitarians in the optimization of the spatial design of camps. The use of parametric modeling approach enables the optimization of space layout planning. It is applied on a case study allowing policy makers to explore scenarios for the decision-making in the camp space planning.

Objective: This prospective in vivo study aimed to compare the clinical behavior of a flowable composite resin (Genial Universal Flo, GC) and a nanohybrid universal composite resin (Tetric Evo Ceram, Ivoclar Vivadent) used in Class I and II direct esthetic restorations in posterior teeth. Methods: A total of 108 Class I and II direct restorations were performed in patients aged between 20 and 60 years. The originality of this study lies in the fact that both materials were placed in pairs, in the same clinical environment (i.e., the same patient and the same type of tooth). The evaluations were performed now of restoration and after 2-weeks, 6-, 12-, and 24-months intervals using clinical examination, clinical photographs, and radiological examination, according to modified USPHS criteria. Statistical analysis was performed using the Fisher exact test and chi-square analysis. Results: At baseline, the universal composite resin showed better esthetic properties such as surface luster, surface staining marginal staining. Both materials regressed significantly over time with no significant difference between groups. Conclusions: Both flowable and nanohybrid composite resins exhibit acceptable clinical performance. The present 24 months of evaluation of different composites showed that the G-ænial Universal Flo could be an effective esthetic material for posterior restoration. No significant difference between both materials over time concerning surface luster, surface staining, and marginal staining.

In the Middle East, there is a gas field that is one of the most challenging gas extraction development projects in the world. The field has a hydrogen sulfide (H2S) concentration in excess of 20%. The field was discovered over 40 years ago, but due to the absence of appropriate technologies to safely extract the reservoirs, field development had been sidelined for several decades. With the advances in oilfield technologies and processes, the field operator commenced field development a few years back. The operator protects its facilities from H2S risk by a comprehensive air management process that uses leading industry gas monitoring and protection systems. During the project design phase, the emphasis focused on fixed facilities and protection at these facilities. However, the possibility of an unexpected gas release and exposure in areas away from the fixed facilities and while in transit within the field soon became apparent. The challenge was to provide for the safety of personnel from the time they entered the field to the time they exited it. An oilfield services company identified the potential risk that possible H2S exposure represented to the safety of personnel while in transit through this field. To address the challenge, the company sought the help of an innovative safety solutions provider. After a series of discussions between the safety solutions provider and the oilfield services company, it became apparent that there was a need to develop a solution that would provide early-warning gas detection while on the move, ensure immediate availability of breathing air protection, and allow communication and documentation of hazards and air status within a crew transportation vehicle. The resulting solution was a vehicle gas protection system (VGPS) with an integrated gas detection system and a proprietary breathing air management system that enables users to transit safely through such terrain.
