I lite drygt ett århundrade gestaltade den svenska värnplikten värderingar som jämlikhet, solidaritet och idén om att man skulle ”göra sin plikt och kräva sin rätt”. Värnplikten började som en rekryteringsmodell 1901, men förvandlades under 1900-talet till en institution i sin egen rätt: uppskattad av pliktskyldiga, Försvarsmakten, samhället, Högern och Vänstern. När det kalla kriget tog slut påböFor little more than a century military service enacted Swedish values of equality, solidarity and doing one's part for the public good. What started out at as mere military recruitment policy in 1901 developed into an institutional feature of Swedish society: appreciated by society, the conscripts, the Armed Forces and by political parties to the left and the right. In a pursuit to preserve milit

This paper reports on the development of novel time resolved spectroscopic imaging techniques for the study of spark ignition phenomena in combustion cells and an SI-engine. The techniques are based on planar laser induced fluorescence imaging (PLIF) of OH radicals, on fuel tracer PLIF, and on chemiluminescence. The techniques could be achieved at repetition rates reaching several hundreds of kiloThis paper reports on the development of novel time resolved spectroscopic imaging techniques for the study of spark ignition phenomena in combustion cells and an SI-engine.

A new jet clustering algorithm-Arclus-is presented. The main difference between this and conventional algorithms is that while the latter in each step join two clusters into one,Arclus joins three clusters into two. The performance ofArclus in terms of the size of hadronization corrections is studied for some jet-reconstruction tasks ine+e− andep collisions, and is found to be as good as or, for s

The fourth version of the Ariadne program for generating QCD cascades in the colour dipole approximation is presented. The underlying physics issues are discussed and a manual for using the program is given together with a few sample programs.The major changes from previous versions are the introduction of photon radiation from quarks and inclusion of interfaces to the LEPTO and PYTHIA programs.

Virtual Compton scattering (VCS) on the proton has been studied at the Jefferson Laboratory using the exclusive photon electroproduction reaction ep→epγ. This paper gives a detailed account of the analysis which has led to the determination of the structure functions PLL-P TT/ε and PLT and the electric and magnetic generalized polarizabilities (GPs) αE(Q2) and βM(Q2) at values of the four-momentum

After a brief discussion of the statistics available to the four LEP experiments at the time of writing and an overview of B-event characteristics, the authors consider in particular the theory, practice and potential pitfalls of neural networks, a new approach to B tagging which attracted a great deal of interest. They then consider some of the QCD aspects of heavy flavour physics. Finally there

We present a toolkit, written in the C++ programming language, for event generation in high energy physics. The toolkit, called MC++, is an attempt to formulate the event generation chain in high in high energy p[article collisions in a transparent and generic way using object oriented programming techniques.

We present a model based upon string dynamics for the small x and large k⊥ parts of the structure functions of a hadron. These ocean partons are taken as those available in the virtual string states, which are resolved by the field pulse q, in case the process is considered as a measuring process. The resulting distributions will for sufficiently small x (x⩽O(Q−4)) behave as 1/x in case we use the

The use of Object Oriented Programming languages and techniques for the development of Monte Carlo simulators for particle production and decay is discussed. For illustration, two specific "template" programs are presented written in Objective-C and in C++, respectively
