Interpolating monthly precipitation by self-organizing map (SOM) and multilayer perceptron (MLP)

There are needs to find better and more efficient methods to interpolate precipitation data in space and time. Interpolation of precipitation is explored using a self-organizing map (SOM) in a region with large complexity of precipitation mechanisms (northern Iran). The technique is used both for regionalization and for interpolating monthly precipitation for stations with missing data for 1-, 2-,

Simultaneous reduction of SO2 and NOx in an entrained-flow reactor

Simultaneous SO2 and NOx reduction in flue gas by the dry furnace sorbent injection process was simulated with an entrained-flow reactor. Several ammonium salts as well as urea were tested. Urea was found to give the highest NOx removal efficiency. By using urea-limestone sorbent, >90% SO2 removal and >80% NOx removal were obtained at Ca/S and N/NOx ratios both equal to 2. The DeNO(x) process is m

On error rates in normal approximations and simulation schemes for Levy processes

Let X = (X(t) : t greater than or equal to 0) be a Levy process. In simulation, one often wants to know at what size it is possible to truncate the small jumps while retaining enough accuracy. A useful tool here is the Edgeworth expansion. We provide a third order expansion together with a uniform error bound, assuming third Levy moment is 0. We next discuss approximating X in the finite variation

A new P-glycoprotein inhibitor from the caper spurge (Euphorbia lathyris).

The macrocyclic lathyrane polyester Euphorbia factor L10 (1a) has been obtained from the seeds of the caper spurge (E. lathyris). The interaction of L10 (1a) and its acetyl derivative (1b) with P-glycoprotein, a multidrug transporter overexpressed in cancer cells and responsible for resistance to chemotherapy, was investigated. The results established lathyrane diterpenoids as a novel chemotype fo

Evaluating Numerical ODE/DAE Methods, Algorithms and Software

Until recently, the testing of ODE/DAE software has been limited to simple comparisons and benchmarking. The process of developing software from a mathematically specified method is complex: it entails constructing control structures and objectives, selecting iterative methods and termination criteria, choosing norms and many more decisions. Most software constructors have taken a heuristic approa

Harald Boklund : kosmopolitiskt, regionalt och nationalromantiskt i Skånes arkitektur 1890-1930

Popular Abstract in Swedish Den i Malmö verksamme arkitekten Harald Boklund (1868-1924) är avhandlingens huvudperson. Vi får följa hans liv och verksamhet från direktörsvåningen på Konstakademien i Stockholm, över studie- och praktikåren i kejsartidens Berlin och det produktiva kompanjonskapet med August Lindvall i industrialismens Malmö till hans roll som föreningsmänniska, arkitekt, kritiker ochThe major part of this thesis is dedicated to a biography of the Swedish architect Harald Boklund (1868-1924), but also deals with the problematic concepts of cosmopolitism, regionalism and National romanticism i Scanian architecture 1890-1930. Harald Boklund was the son of Johan Boklund, a famous painter and director of the Swedish Academy of Fine Arts in Stockholm. Harald Boklund got his educati

Demokrati i EU. Demokratirådets rapport 2003.

Europa är i dag platsen för ett stort politiskt experiment. Frågan är om det går att skapa ett medborgarnas Europa. Uppgiften är att samtidigt demokratisera, konstitutionalisera och effektivisera Europeiska unionen. 2003 års rapport från Demokratirådet diskuterar med utgångspunkt från EU:s framtidskonvent den pågående reformprocessen och Sveriges bidrag till denna europeiska framtidsdebatt.

Liberty, Law and Social Construction

In this article Hobbes’s view of the commonwealth, and of law and liberty within it, is discussed from the point of view of social ontology. The artificial character of the commonwealth and the constitutive function of the covenant is put in terms of the institutional world being constructed through collective intentionality, which is performative, self-referential, and collective, and which serve

Vägval vid utrymning - utrymningsförsök med gröna blinkande lampor vid nödutgångar

Unannounced evacuation experiments were performed in an office building and a cinema theatre in order to investigate if green flashing lights at emergency exit can influence exit choice, i.e., make people choose the emergency exits. Experiments were documented using standard video cameras and participants filled out a questionnaire. The results show that green flashing lights influenced exit choic

Globalization Movement Comes to Town

The ”Battle of Seattle” only entered the main political agenda of Sweden in September 2000, during the IMF protests in Prague. In this article, the roots and development of "the globalization movement" in Sweden is examined. In particular, the relation between it and the Swedish Labour movement is discussed. The article begin by tracing the roots of the globalization movement in various new social
