Given the importance of availability sufficient and accurate information on the structural characteristics of mangroves to develop conservation and restoration programs for these ecosystems, this study investigates and maps the structural characteristics of the coastal and island forms of the mangroves in the Hara Biosphere Reserve. To this end, through a field inventory (32 sample plots with t...

In the event of a severe incident with a high impact and low probability of occurrence, distribution networks may be separated from upstream networks and several feeders may be disconnected simultaneously within the distribution networks. In such circumstances, to maximize the resilience of the distribution networks and to prevent long-term global outages, they are reconfigured and islanded to ...

The work introduces Island Restoration Scheme (IRS) with online restoration of missing sensor data. This paper focuses on the Restoration Scheme with Intelligent Sensing and Monitoring and also entails fuzzy logic theory representation for alarm analysis in electrical power system based on expert system . Theoretical and mathematical representation of alarm analysis for fault diagnosis has also...

Genetic marker studies can assist restoration practice through selection of seed sources that conserve historical levels of gene diversity and population genetic differentiation. We examined genetic variation and structure within and among mainland and island populations of Elymus glaucus, a perennial bunchgrass species native to western North American grasslands that is targeted for grassland ...

A programme of planting native trees on Quail Island in Lyttelton Harbour has been proposed by the Otamahua/Quail Island Ecological Restoration Trust. The impact that this would have on the Maori and European historic and archaeological sites on the island is assessed. It is concluded that in several areas the planting and growth of trees would adversely affect these sites (some of which are pr...

Restoration of distribution system in cold weather and after long interruptions creates cold load pickup problem due to loss of diversity among the loads in residential area. Under such conditions the distribution system load may have to be restored step by step, using sectionalizing switches to prevent overheating of substation transformer. The order in which the sections are restored has a si...

Due to the growing use of Plug-in Electric vehicles in transportation networks, scheduling the charge/discharge of electric vehicles in parking lots can have great impacts on the distribution network's resiliency. This paper presents a Bi-level optimization model to improve the resiliency of the distribution network that takes into account the interaction between the distribution network island...

In this paper, a distributed generation including diesel generators, wind turbines, and microturbines are introduced, and their mathematical model is described using the Taylor expansion method. With the goal of computational complexity eliminating, the reduced order model (ROM) of microgrid components is considered. The results of the ‌‌studies indicate that the microgrid frequency is unstable...
