Software for physics of tau lepton decay in LHC experiments
Software development in high energy physics experiments offers unique
experience with rapidly changing environment and variety of different standards
and frameworks that software must be adapted to. As such, regular methods of
software development are hard to use as they do not take into account how
greatly some of these changes influence the whole structure. The following
thesis summarizes development of TAUOLA C++ Interface introducing tau decays to
new event record standard. Documentation of the program is already published.
That is why it is not recalled here again. We focus on the development cycle
and methodology used in the project, starting from the definition of the
expectations through planning and designing the abstract model and concluding
with the implementation. In the last part of the paper we present installation
of the software within different experiments surrounding Large Hadron Collider
and the problems that emerged during this process.Comment: Thesis submitted to Applied Computer Science Department in partial

Detecting Conflicts and Inconsistencies in Web Application Requirements
Web applications evolve fast. One of the main reasons for this
evolution is that new requirements emerge and change constantly. These new
requirements are posed either by customers or they are the consequence of
users’ feedback about the application. One of the main problems when dealing
with new requirements is their consistency in relationship with the current
version of the application. In this paper we present an effective approach for
detecting and solving inconsistencies and conflicts in web software
requirements. We first characterize the kind of inconsistencies arising in web
applications requirements and then show how to isolate them using a modeldriven
approach. With a set of examples we illustrate our approach
JWalk: a tool for lazy, systematic testing of java classes by design introspection and user interaction
Popular software testing tools, such as JUnit, allow frequent retesting of modified code; yet the manually created test scripts are often seriously incomplete. A unit-testing tool called JWalk has therefore been developed to address the need for systematic unit testing within the context of agile methods. The tool operates directly on the compiled code for Java classes and uses a new lazy method for inducing the changing design of a class on the fly. This is achieved partly through introspection, using Java’s reflection capability, and partly through interaction with the user, constructing and saving test oracles on the fly. Predictive rules reduce the number of oracle values that must be confirmed by the tester. Without human intervention, JWalk performs bounded exhaustive exploration of the class’s method protocols and may be directed to explore the space of algebraic constructions, or the intended design state-space of the tested class. With some human interaction, JWalk performs up to the equivalent of fully automated state-based testing, from a specification that was acquired incrementally
A requirements engineering framework for integrated systems development for the construction industry
Computer Integrated Construction (CIC) systems are computer environments through which
collaborative working can be undertaken. Although many CIC systems have been developed to demonstrate the
communication and collaboration within the construction projects, the uptake of CICs by the industry is still
inadequate. This is mainly due to the fact that research methodologies of the CIC development projects are
incomplete to bridge the technology transfer gap. Therefore, defining comprehensive methodologies for the
development of these systems and their effective implementation on real construction projects is vital.
Requirements Engineering (RE) can contribute to the effective uptake of these systems because it drives the
systems development for the targeted audience. This paper proposes a requirements engineering approach for
industry driven CIC systems development. While some CIC systems are investigated to build a broad and deep
contextual knowledge in the area, the EU funded research project, DIVERCITY (Distributed Virtual Workspace
for Enhancing Communication within the Construction Industry), is analysed as the main case study project
because its requirements engineering approach has the potential to determine a framework for the adaptation of
requirements engineering in order to contribute towards the uptake of CIC systems
A Model-Driven approach for functional test case generation
Test phase is one of the most critical phases in software engineering life cycle to assure the final system quality. In this context, functional system test cases verify that the system under test fulfills its functional specification. Thus, these test cases are frequently designed from the different scenarios and alternatives depicted in functional requirements. The objective of this paper is to introduce a systematic process based on the Model-Driven paradigm to automate the generation of functional test cases from functional requirements. For this aim, a set of metamodels and transformations and also a specific language domain to use them is presented. The paper finishes stating learned lessons from the trenches as well as relevant future work and conclusions that draw new research lines in the test cases generation context.Ministerio de EconomĂa y Competitividad TIN2013-46928-C3-3-
