While the government of Hong Kong has acknowledged the need to increase renewable energy contributions in its fuel mix, the implementation of renewable energy projects in the region is constrained by complex topography and limited land availability. To overcome these challenges, a pragmatic solution is devised through the use of a site suitability analysis which expedites the identification of
With the urgent demand for ultralow-temperature refrigerators worldwide, the operation reliability and stability of the refrigeration system becomes greatly crucial. In this study, a -80 oC ultralow-temperature cascade refrigeration system (CRS) is developed. From aspects of global warming potential (GWP) and ozone depletion potential (ODP), the environmentally friendly refrigerants R290 and R170
Detta examensarbete ämnar att undersöka om och hur man skulle bygga en modell för att kunna beräkna utsläppen av växthusgaser vid förändringar av transmissionskapacitet. Arbetet avhandlar hur det nuvarande elsystemet är uppbyggt och påverkan på utsläppen av växthusgaser ifrån ökad produktion av förnyelsebar elproduktion och ökad transmission av elektricitet. Utifrån att studera vind- och lastdataIn the light of the importance of climate change and the emissions that have induced it, the ability to calculate the effect on emissions by changing transmission capacity is vital. A model to perform such indicative calculations is developed in this thesis. After researching how the current electricity system is organised, the effects on GHG emissions that are expected from increased renewable el
Popular Abstract in Swedish Slå vatten i småbitar Många av de små molekyler som omger oss kan verka helt alldagliga. Vatten, koldioxid, syre, metan; de bara finns där, i våra kroppar, i våra lungor, överallt. Men så börjar någon tala om klimatförändringar, och att förstå de banala molekylerna blir avgörande för hela vår existens. Koldioxid, metan och vatten är växthusgaser, och det finns idag merThis dissertation contains seven studies exploring novel instrumentation for ion and electron spectroscopy, including their applicability at storage ring light sources. The studies focus on instrumentation to study decay, dynamics and dissociation of photoexcited molecules, and the possibility to host such instruments at MAX~IV.

A Soft X-ray FEL (the SXL) is currently being designed at the MAX IV Laboratory. In the work to adapt the FEL to the scientific cases several advanced options are being studied for coherence enhancement, generation of short pulses and two-color pulses. We will discuss the current status and initial results of the schemes studied, especially regarding the FEL performance with the features of the MA
Universities are powerful drivers to create and advance knowledge on sustainable development. Furthermore, they can be used as a controlled environment to apply innovative technologies and approaches. This process also embraces industry and government, in the triple helix innovation model, as in the University of Campinas (Unicamp), Brazil—one of the best Latin American universities (3rd)—and imme

Investment in renewable energy sources for military purposes is to dramatically increase in the coming years due to tactical, geopolitical, economic and environmental reasons. Major military powers have started to explore various opportunities for alternative liquid fuels while small countries are facing multiple barriers. The Military of Lithuania has been chosen as a research object to reveal wh
The quasi-stationary state characterizing the saturation of a single-pass free-electron laser is governed by the Vlasov equation obtained by performing the continuum limit of the Colson-Bonifacio model. By means of a statistical treatment, this approach allows to predict analytically the saturated laser intensity as well as the final electron-beam energy distribution. In this paper we consider the
Observational epidemiology has made outstanding contributions to the discovery and elucidation of relations between lifestyle factors and common complex diseases such as type 2 diabetes. Recent major advances in the understanding of the human genetics of this disease have inspired studies that seek to determine whether the risk conveyed by bona fide risk loci might be modified by lifestyle factors

This study focuses on the introduction of new nuclear, particularly Small Modular Reactors (SMRs) in Sweden. The Swedish Government has decided on a revival for nuclear energy where SMRs are an important contribution to reach the goal of a total output of at least 2 500 MW by 2035. In this stage when much is unclear about the re-introduction and SMRs are under development media is an important age
There has been active research in the development of new rigid biobased aromatic dicarboxylate monomers that can replace the widely used fossil-based dimethyl terephthalate in polyester production. In this work, a new biobased dicarboxylate monomer with a spiroacetal unit was synthesized from biobased vanillin and pentaerythritol, which aims to partially or completely replace the fossil-based
Kinesthetic teaching allows human operators to reprogram part of a robot’s trajectory by manually guiding the robot. To allow kinesthetic teaching, and also to avoid any harm to both the robot and its environment, Cartesian impedance control is here used for trajectory following. In this paper, we present an online method to modify the compliant behavior of a robot toward its environment, so that
