Islanding and Reconnection of Converter Based Distributed Generation Systems

In this paper a method for reconnecting islanded distributed generation systems is presented. Islanding of a distributed generation system may result from a fault or malfunction of protective elements. The behavior of local voltage and frequency control in case of islanding is investigated. A method for reconnecting the distributed generation system and the behavior of voltage and frequency contro

Impact of Insertion Devices on the MAX IV Storage Rings

There will be multiple compensations employed for in- sertion devices in the MAX IV storage rings. Apart from well-known dipole corrections and previously detailed local and global linear optics matching, certain insertion devices in the MAX IV storage rings will also require nonlinear optics adjustments and/or skew quadrupole corrections. The goal of such corrections is ensuring sufficient dynami

Biologically Interesting Compounds from Natural Sources.

Natural products have traditionally played a major role in the drug discovery process. Besides constituting extremely popular drugs in the market, and an ever-increasing source of interesting and novel chemical structures, they have also aided the characterization of many a pharmacological target. And although natural product-oriented research has suffered from a declining interest from the pharma

A CP-LP approach to network management in OSPF routing

In this paper, we consider a routing problem related to the widely used Open Shortest Path First (OSPF) protocol, which is considered a challenge within the Constraint Programming (CP) community. We address the special version of OSPF which requires unique and symmetrical paths. To solve this problem, we propose a novel hybrid approach which combines CP and Linear Programming (LP). Our approach em

Weighted Subspace Fitting of Interferometric Phases for Multibaseline SAR Interferometry

In this paper, we deal with the problem of exploiting baseline diversity of a multichannel interferometric SAR system to overcome the layover problem. The problem arises when different height contributions collapse in the same range-azimuth resolution cell, due to the presence of strong terrain slopes or discontinuities in the sensed scene. The multilook framework is adopted to counteract the pres

On the pharmacodynamics, pharmacokinetics and metabolism of sulphonylurea and its metabolites - with special reference to glibenclamide

The pharmacodynamics (PD), pharmacokinetics (PK) and metabolism of the sulphonylurea(SU) and its metabolites (M1 and M2) , and of another SU, glipizide (Gz) were studied in diabetes patients and healthy volunteers. In one study Caucasians and Chinese were compared. Sensitive and selective methods for determination of drug levels and concentrations of insulin and proinsulin were used. The terminal

Ett Jerusalem i Skåne

The parish church of Dalby is probably the oldest preserved church in Scandinavia and thus also the oldest building in Scandinavia that is still in use. Its construction began around 1060. Some features of the original church display influence from Northern Germany, more specifically Hildesheim; significant additions and alterations made in the 12th century display influence from the Cathedral of

Commissioned by the Deutsches Historisches Museum in Berlin, this essay maps the construction of Sweden's national self-image through visual culture, after World War II.

Varför blev skinheadskulturen högerextremistisk?

Vi som kommer ihåg skinheads från 1980-talet, kommer ihåg en grupp aggressiva och rasistiska män som gärna ville provocera med nazistiska symboler och sitt speciella utseende. Men skinheadskulturen har inte alltid varit högerextrem. Tvärtom är den ursprungliga skinheadskulturen mångkulturell och ett av få exempel på en subkultur som har sina rötter i det mångkulturella. Hur kom det sig att en mult
