A risk assessment of vegetation zone responses to climate change was conducted using the classical Holdridge life zone model on the Loess Plateau of Northwest China. The results show that there are currently ten vegetation zones occurring on the Loess Plateau (1950–2000), including alvar desert, alpine wet tundra, alpine rain tundra, boreal moist forest, boreal wet forest, cool temperate desert...
Partially Protected Areas (PPAs) are a widely-used management tool, yet comparatively little is known about their effectiveness compared to more commonly studied No-Take Marine Reserves (NTMRs). Here, we examine the efficacy of two kinds PPAs (with and without spearfishing) within Great Barrier Reef Park (GBRMP) that subject range fishing limitations, assess utility as marine park zoning fisher...
Economic load dispatch is to operate thermal generators economically with fulfilling demand. This economic problem becomes highly complex and non-linear after considering various operating constraints like valve-point loading effect, generator constraints, prohibited zone. The recently developed physics law-based artificial electric field algorithm has been applied solve ELD problems. explorati...
Ultra Wide Band (UWB) wireless communications offers a radically different approach to wireless communication compared to conventional narrow band systems. Global interest in the technology is huge. This paper reports on the state of the art of UWB wireless technology and highlights key application areas, technological challenges, higher layer protocol issues, spectrum operating zones and futur...
