Microbial populations adapt to environmental fluctuations through random switching of fitness-related traits in individual cells. This increases the likelihood that a subpopulation will be adaptive in a future milieu. However, populations are particularly challenged when several environment factors change simultaneously. We suggest that a population can rapidly adapt to multiple environmental c...

Energy hub systems integrate various energy sources and interconnect different carriers in order to enhance the flexibility of system. In this paper, a cooperative framework is proposed which network hubs collaborate together share their resources reduce costs. Each has several including CHP, boiler, renewable sources, electrical chiller, absorption chiller. Moreover, storages are considered fo...

Abstract The Energyhub@Sea concept is one of the four research applications Space@Sea project funded by EU’s Horizon 2020 program (GA number: 774253). focus this paper evaluation energy demands an self-sufficient maintenance platform at location Helgoland in North Sea. In view this, a standardized modular floater was developed as offshore wind operation and base, which following referred to O&a...

The energy absorption of the wave energy converters (WEC) characterized by a limited stroke length —like the point absorbers developed at Uppsala University—depends on the sea level variation at the deployment site. In coastal areas characterized by high tidal ranges, the daily energy production of the generators is not optimal. The study presented in this paper quantifies the effects of the ch...

In this paper, a comprehensive model for hub location-routing problem is proposed which no network structure other than connectivity is imposed on backbone (i.e. network between hub nodes) and tributary networks (i.e. networks which connect non-hub nodes to hub nodes). This model is applied in public transportation, telecommunication and banking networks. In this model locating and routing is c...
