1. Optimisation of Local and National Energy Systems : Development and Use of the MODEST Model
Sammanfattning : Energy may be supplied by a multitude of components. Computer simulation helps in finding a beneficial system design. The energy-system optimisation model MODEST has been developed, and it has been applied to municipal, regional, and national energy systems. LÄS MER
2. System Studies and Simulations of Distributed Photovoltaics in Sweden
Sammanfattning : Grid-connected photovoltaic (PV) capacity is increasing worldwide, mainly due to extensive subsidy schemes for renewable electricity generation. A majority of newly installed systems are distributed small-scale systems located in distribution grids, often at residential customers. LÄS MER
3. Seasonal variations in general activity, behaviour and cutaneous glandular structures in reindeer (Rangifer tarandus L.)
Sammanfattning : The locomotor activity of the reindeer is separated into a diurnal and a nocturnal phase which, in turn, consists of a number of short-term activity bursts. The onset and termination of diurnal and nocturnal activity are largely in synchrony with sunrise and sunset. LÄS MER
4. Carbon stock and fluxes in Nyungwe forest and Ruhande Arboretum in Rwanda
Sammanfattning : Conservation and sequestration of carbon in forest ecosystems are potential strategies to reduce or stabilize the atmospheric greenhouse gas concentrations and mitigate climate change. Estimating the... LÄS MER
5. Boreal land surface water and heat balance : Modelling soil-snow-vegetation-atmosphere behaviour
Sammanfattning : The water and heat exchange in thesoil-snow-vegetation-atmosphere system was studied in order toimprove the quantitative knowledge of land surface processes.In this study, numerical simulation models and availabledatasets representing arable land, sub-alpine snowpack, andboreal forest were evaluated at both diurnal and seasonaltimescales.
