Everything is INTERRELATED:Teaching Software Engineering for Sustainability
Sustainability has become an important concern across many disciplines,and software systems play an increasingly central role in addressing it. However, teaching students from software engineering and related disciplines to effectively act in this space requires interdisciplinary courses that combines the concep to of sustainability with software engineering practice and principles. Yet, presently little guidance exist on which subjects and materials to cover in such courses and how, combined with a lack of reusable learning objects. This paper describes a summer school course on Software Engineering for Sustainability (SE4S). We provide a blueprint for this course, in the hope that it can help the community develop a shared approach and methods to teaching SE4S. Practical lessons learned from delivery of this course are also reported here, and could help iterate over the course materials, structure, and guidance for future improvements. The course blueprint, availability of used materials and report of the study results make this course viable for replication and further improvement
Measurement of the hadronic final state in deep inelastic scattering at HERA
We report on the first experimental study of the hadronic final state in deep inelastic electron-proton scattering with the H1 detector at HERA. Energy flow and transverse momentum characteristics are measured and presented both in the laboratory and in the hadronic center of mass frames. Comparison is made with QCD models distinguished by their different treatment of parton emission
Scaling violations of the proton structure function f2 at small x
An analysis is presented of scaling violations of the proton structure function F2(x,Q2) measured with the H1 detector at HERA in the range of Bjorken x values between x = 3 × 10-4 and 10-2 for four-momentum transfers Q>2 larger than 8.7 GeV2. The structure function F2(x,Q2) is observed to rise linearly with ln Q2. Under the assumption that the observed scaling violations at small x ≤ 0.01 are described correctly by perturbative QCD, an estimate is obtained of the gluon distribution function G(x,Q02) at Q22 = 20 GeV2. © 1994.0320 auteursSCOPUS: ar.jinfo:eu-repo/semantics/publishe
Measurement of inclusive jet cross-sections in photoproduction at HERA
The inclusive jet cross section in photoproduction has been measured as a function of transverse energy and pseudorapidity using the H 1 detector at the HERA electron-proton collider. The results are compared with leading order QCD calculations. © 1993.0SCOPUS: ar.jinfo:eu-repo/semantics/publishe
A Search for leptoquarks, leptogluons and excited leptons in H1 at HERA
A direct search for new particles in the H1 experiment at HERA is presented for masses ranging from 35 GeV up to ∼ 250 GeV. The data sample of 24 nb−1 accumulated during the first year of operation was analysed for signatures of scalar and vector leptoquarks, leptogluons, excited electrons and excited neutrinos with flavours of the first generation. No evidence for the production of such particles was found in various possible decay channels. Rejection limits are derived
Total photoproduction cross-section measurement at HERA energies
We present first results on the total photoproduction cross section measurement with the H1 detector at HERA. The data were extracted from low Q2 collisions of 26.7 GeV electrons with 820 GeV protons. The γp total cross section has been measured by two independent methods in the γp center of mass energy range from 90 to 290 GeV. For an average center of mass energy of 195 GeV a value of σtot (γp) = 159 ± 7 (stat.) ± 20 (syst.) μb was obtained. © 1993.0320 auteursSCOPUS: ar.jinfo:eu-repo/semantics/publishe
