In November 2009 a Swedish twitterer died in a car accident. Even though @Just_Tea wasn’t a celebrity, condolences and displays of public mourning stacked up from her followers and the Swedish blogosphere. However, there was also disapproving voices, criticizing the public displays of grief of someone whom few had met and even fewer could call friend. The criticism and the subsequent discussions o

Popular Abstract in Swedish Målet med arbetet var att öka mängden vindkraft, solel och annan distribuerad generering (DG) som kan anslutas till befintliga distributionsnät på ett snabbt och kostnadseffektivt sätt. Att införa aktiv spänningsreglering i nätet, istället för installation av nya ledningar, har identifierats som en lämplig strategi. Då denna princip bygger på att DG-enheternas produktioDistributed generation (DG), i.e. generation connected to the low and medium voltage distribution network (DN), has been increasing a lot during recent years. Thus the traditional assumption of a unidirectional power flow and a voltage decrease along the distribution feeders is no longer valid in all operation conditions. Voltage control in these networks is often limited to the on-load tap change

Many studies identify energy efficiency as the most important and least costly option for reducing CO2-emissions while at the same time contributing to other policy objectives. The main challenge seems to be how to design, implement and evaluate policy to ensure that these opportunities are captured and policy perceived as legitimate. There is often a gap between rhetoric or broadly stated objecti

This paper investigates the often ambivalent assessment of the landscapes that have been shaped by Swedish modernity and the welfare policy. This ambivalence could be noticed in different medias, I would argue, for instance in art, photography and novels. In Lefebvrian terms I think you could identify an ongoing negotiation between the modern welfare state’s conceptualization of space and the live

The Forward Wall Detector (FWD) is designed to identify projectile-like fragments from heavy-ion reactions at the CELSIUS storage ring in Uppsala, Sweden. FWD covers the polar angle from 3.9° to 11.7° with geometrical efficiency of 81%. The single-detection module can be either of phoswich type (10 mm fast plastic+80 mm CsI(Tl)) or ΔE−E telescope (750 μm Si+80 mm CsI(Tl)). It is expected to have c

In an industrial plant, availability is an important factor since increased availability often gives an increase of final production, which in many cases means an increased profit for the company. The purpose of using buffer tanks is to increase the availability either by separating production units from each other or by minimizing flow variations. However, the methods for achieving this goal is n
