Wind-Wave Interaction Effects on a Wind Farm Power Production

In the current study, the effects of the nonlocally generated long sea surface waves (swells) on the power production of a 2 × 2 wind farm are investigated by using large-eddy simulations (LES) and actuator-line method (ALM). The short sea waves are modeled as a roughness height, while the wave-induced stress accounting for swell effects is added as an external source term to the momentum equation

LPM-Effect in Monte Carlo Models of Radiative Energy Loss

Extending the use of Monte Carlo (MC) event generators to jets in nuclear collisions requires a probabilistic implementation of the non-abelian LPM effect. We demonstrate that a local, probabilistic MC implementation based on the concept of formation times can account fully for the LPM-effect. The main features of the analytically known eikonal and collinear approximation can be reproduced, but we

Modelling managed forest ecosystems in Sweden : Poster presentation:

In this work, the forestry-enabled dynamic vegetation model LPJ-GUESS was used to simulate forest standing volume for the three main regions of Sweden. At the regional scale, the model results were evaluated against observational data from the Swedish National Forest Inventory. Carbon fluxes of net ecosystem exchange (NEE), gross primary productivity (GPP), and ecosystem respiration (Reco) were si

The Electoral Consequences of Environmental Accidents: Evidence from Chernobyl

This paper examines the relationship between environmental accidents and voting. Following the 1986 Chernobyl disaster, environmentalist parties entered parliaments in several nations. This paper uses Chernobyl as a natural experiment creating variation in radioactive fallout exposure over Sweden. I match municipality-level data on cesium ground contamination with election results for the environm

Estimation of residence time and catchment area for spring water using radioactive isotope and groundwater flow model

Spring water, however, is often formed in complex geological formations and therefore it is difficult to determine the catchment area contributing to the flow. The Sayanokami spring, located in western part of Fukuoka City, Japan, is such a spring and an important water resource for the local agriculture. In order to better understand the hydrological properties of infiltration and groundwater pro

The Sound of Their Wings: Desert Locusts and Conflicts in Africa

Do negative income shocks increase conflict risk? I study the relationship between desert locust infestations and conflict in 26 African countries. Combining geolocalized data on locust swarms and bands with information on conflict events, I construct two panel datasets at spatial resolutions 0.5◦ × 0.5◦ and 0.1◦ × 0.1◦, covering the years 1997–2017. I find a negative relationship between locust i

Drogförebyggande arbete riktat mot barn och ungdom : Vad som görs i skola och kommun i två kommuner i Skåne

This paper is about drug prevention. In my paper the aim is to examine when, where and how the drug prevention work, by law, is being realized, on local levels, in school and municipality, towards youth. My central questions are among others: What does it imply, how the municipality and school value the drug prevention work?, Which prevention programs do the municipality and school use? and Does

Nature-Based Tourism in the Cuyabeno Reserve of Ecuador- A Choice Experiment Survey

Ecotourism is a strong and upcoming branch of the traditional tourism industry. Is there a strong demand among tourists for travelling in accordance with ecological and ethical principles? This study uses an established framework for the definition of ecotourism to estimate the demand for some ecotourism criteria among visitors at the Cuyabeno Reserve in Ecuador. A survey based on the Choice Exper

Hidden spin polarization in the centrosymmetric Mo S2 crystal revealed via elliptically polarized terahertz emission

The spin polarization in centrosymmetric molybdenum disulfide (MoS2) bulk crystal is recorded by helicity dependent photocurrent exposed as elliptically polarized terahertz (THz) emission. We assign this observation to hidden spin polarization due to the local Dresselhaus effect induced by the molybdenum atomic site asymmetry. This spin polarization induces ultrafast optically controlled circular

Closing in on critical net-baryon fluctuations at LHC energies: Cumulants up to third order in Pb–Pb collisions

Fluctuation measurements are important sources of information on the mechanism of particle production at LHC energies. This article reports the first experimental results on third-order cumulants of the net-proton distributions in Pb–Pb collisions at a center-of-mass energy sNN=5.02 TeV recorded by the ALICE detector. The results on the second-order cumulants of net-proton distributions at sNN=2.7

The Presidential, Parliamentary and Local Elections in Malawi, May 2014

On 20 May 2014, Malawi arranged tripartite elections for president, parliament and local councils. The elections were remarkable for several reasons, seen from both an African and a Malawian perspective. Despite an uneven electoral playing field, the elections were highly competitive, ultimately leading to the country’s second turnover of power when opposition challenger Peter Mutharika defeated t

Double directional radio propagation measurements and radio channel modelling pertinent to mobile MIMO communications in microcells

For simulating mobile MIMO performance, local area SNR variations can be reproduced if small-scale fading distributions are known, transmit bandwidths can be chosen appropriately if flat fading bandwidths are known, and, assuming plane waves, spatial covariance functions can be estimated if power-weighted histograms for angles of arrival (AOA) and angles of departure (AOD) are known. This paper re

Reglersystem för styrning av stabiliserad plattform

The report describes a control system for a new mechanical design of a stabilized platform. The platform design is based on rotation of two medges. It has the advantage that mechanical design is very simple. A key difficulty is that the transformation from platform orientation angles to gimbal angles in nonlinear and that it has a singularity. A control system based on local linearization of the t

“There is no lake here, the lake is down there!” An inquiry on the transformation of environment and culture in Burdur Region.

Burdur Lake, which is located in southwest of Turkey in Lake Region, and has been drying rapidly in the last 30 years. Disappearance of the water from the lake brings dramatic changes to the region on both socio-economic and cultural levels. This paper explores the processes that brought Burdur Lake and its locals to the point where the lake is today. Transformations in cultural habits and everyda

Kohn-Sham density functional theory for quantum wires in arbitrary correlation regimes

We use the exact strong-interaction limit of the Hohenberg-Kohn energy density functional to construct an approximation for the exchange-correlation term of the Kohn-Sham approach. The resulting exchange-correlation potential is able to capture the features of the strongly correlated regime without breaking the spin or any other symmetry. In particular, it shows "bumps" (or barriers) that give ris
