Abstract Handover (HO) which can make user equipment (UE) communicate with the eNodeB (evolves NodeB) with the highest signal quality will have bad performance in high-speed railway scenario. In this paper, detailed introduction is made on Layer3 (L3) filtering theory to help solve this problem. HO measurement and HO decision procedure based on L3 filtering are designed and implemented in a dyn...

Most of the issues regarding desertification are always related to soil fertility and water quality [1,2]. Hence United Nation Framework Convention on Climate Change (UNFCCC) seriously globalized the issues of desertification in 1992. The developed and developing including hilly mountainous countries are the conference of the parties and so as Nepal [3]. The catchments in hill and Himalayan reg...

Populations of large carnivores can persist in mountainous environments following extensive land use change and the conversion of suitable habitat for agriculture and human habitation in lower lying areas of their range. The significance of these populations is poorly understood, however, and little attention has focussed on why certain mountainous areas can hold high densities of large carnivo...

Despite becoming one of China’s fastest expanding and most valuable forest land uses, bamboo’s role in livelihoods and rural development is poorly understood. Detailed quantitative data from 240 households were used to study the contribution of bamboo to household income and rural livelihoods in 12 remote and mountainous villages in southern China. Bamboo was a ubiquitous and highly utilised re...

Protected areas in mountains are regularly in the focus of international efforts to conserve the environment and enable sustainable development. The following article analyses the current extend of protection in mountainous versus non-mountainous areas, sheds light on the rationales behind the establishment of mountain protected areas, and proposes directions for future endeavours in protecting...

The objective of this study is to estimate the daily extreme precipitation distribution in an Asian monsoon region considering orographic precipitation in mountainous areas. For this purpose, the APHRODITE data set and precipitation observations from 150 raingauges throughout Thailand were used as the main input. First, a bias-correction for underestimated precipitation in the APHRODITE data se...

Spatial interpolation of rain gauge data is important in forcing of hydrological simulations or evaluation of weather predictions, for example. This paper investigates the application of statistical distance, like one minus common variance of observation time series, between data sites instead of geographical distance in interpolation. Here, as a typical representative of interpolation methods ...

Climate change velocity is a vector depiction of the rate of climate displacement used for assessing climate change impacts. Interpreting velocity requires an assumption that climate trajectory length is proportional to climate change exposure; longer paths suggest greater exposure. However, distance is an imperfect measure of exposure because it does not quantify the extent to which trajectori...
