top quark mass measurement using the Template Method at cdf
Physical Review D, 2011Co-Authors: T Aaltonen, Alvarez B Gonzalez, S Amerio, D Amidei, A Anastassov, A Annovi, J Antos, G ApollinariAbstract:We present a measurement of the top quark mass in the lepton+jets and dilepton channels of t$$\bar{t}$$ decays using the Template Method. The data sample corresponds to an integrated luminosity of 5.6 fb-1 of p$$\bar{p}$$ collisions at Tevatron with √s = 1.96 TeV, collected with the CDF II detector. The measurement is performed by constructing Templates of three kinematic variables in the lepton+jets and two kinematic variables in the dilepton channel. The variables are two reconstructed top quark masses from different jets-to-quarks combinations and the invariant mass of two jets from the W decay in the lepton+jets channel, and a reconstructed top quark mass and mT2, a variable related to the transverse mass in events with two missing particles, in the dilepton channel. The simultaneous fit of the Templates from signal and background events in the lepton+jets and dilepton channels to the data yields a measured top quark mass of Mtop = 172.1±1.1 (stat)±0.9 (syst) GeV/c2.

Automated refactoring of super-class Method invocations to the Template Method design pattern
Information and Software Technology, 2017Co-Authors: Vassilis Zafeiris, Sotiris H. Poulias, N. A. Diamantidis, E. A. GiakoumakisAbstract:Abstract Context: Implementation inheritance, i.e., overriding of concrete Method implementations through subtyping, is prone to potential class contract violations. Call Super is a code pattern that employs implementation inheritance for extending a Method’s behaviour. In Call Super the overriding Method includes in its body an invocation to the overridden Method. Template Method is a design pattern that enables extensions to a multi-step procedure without overriding its concrete implementation. Instead, subclasses provide different variants of the Template Method’s behaviour through implementation of abstract Method definitions (interface inheritance). Objective: This work studies the automated refactoring of Call Super to Template Method , contributing, thus, to replacement of implementation inheritance with interface inheritance. Method: We introduce an algorithm for the discovery of refactoring candidates that is based on an extensive set of refactoring preconditions. Moreover, we specify the source code transformation for refactoring a Call Super instance to Template Method . An implementation of the proposed approach is evaluated on a set of open source Java projects. Results: The evaluation results highlight (a) the frequent occurrence of the Call Super pattern among Method overridings, (b) the potential provided by our Method for discovery and elimination of several non-trivial Call Super instances and (c) the resulting code improvement, as reflected by the Specialization Index metric and the alignment of refactored code with the programmer’s intent. The application of all refactorings identified on a set of benchmark projects and the successful execution of their test suites provide empirical evidence on the soundness of the refactoring procedure. Runtime performance results support the scalability of the proposed Method. Conclusion: The proposed Method automates the replacement of implementation inheritance with interface inheritance through refactoring Call Super instances to Template Method . The empirical evaluation of the Method supports its applicability, soundness and runtime efficiency.
