Product line process theory

Fatemeh Ghassemi, Mohammad Reza Mousavi
2016 Journal of Logical and Algebraic Methods in Programming  
Product Line Calculus of Communicating Systems (PL-CCS) is a process calculus for behavioral modeling of SPLs, in which variability can be explicitly modeled by a binary variant operator.  ...  Software product lines (SPLs) facilitate reuse and customization in software development by genuinely addressing the concept of variability.  ...  Also, to facilitate reasoning about product lines and also establish an algebraic theory for product line processes, we provide a sound and complete axiomatization for product line and configuration bisimilarity  ...

String theory at LHC using Higgs production and decay from string balls

Gouranga C. Nayak
2011 Journal of High Energy Physics  
Hence in the absence of black hole production at LHC an enhancement of high $p_T$ diphotons and $ZZ$ pairs at LHC can be useful signatures for string theory at LHC.  ...  Since the matrix element for Higgs production in parton-parton collisions via string regge excitations is not available we compute $\frac{d\sigma}{dp_T}$ of photon production from string regge excitations  ...  The solid line is Higgs production from black holes with string mass scale M s = 1 TeV. The dotted line is for Higgs production from NLO pQCD processes with M H =120 GeV.  ...

Towards a learning curve theory for batch production

A. P. Chatzimichali, V. D. Tourassis
2008 2008 IEEE International Conference on Industrial Engineering and Engineering Management  
Due to frequent setups and retooling, quality issues arise that hold back the line from a full ramp up.  ...  In this paper, we stipulate that in batch production the process of industrial learning becomes more complex and thus the archetypal exponential or power curve is not sufficiently rich to describe it.  ...  The observation that the performance of a task or a process improves over time or repetition is central to the theory of learning.  ...
