Reference architectures for specific domains can provide significant benefits in productivity and quality for real-time systems development. These systems require an exact characterisation based on quantitative evaluation of architectural features referred to timing properties, such as performance, reliability, etc. In this work, an UML-based tool has been used to obtain a measure of performanc...

One human factors challenge is predicting operator performance in novel situations. Approaches such as drawing on relevant previous experience, and developing computational models to predict operator performance in complex situations, offer potential methods to address this challenge. A few concerns with modeling operator performance are that models need to realistic, and they need to be tested...

Performance related problems play a key role in the Software Development Process (SDP). In order to evaluate the performance of a software architecture we defined and implemented a technique mapping the initial UML model into a performance model afterwards analyzed, implemented into the ArgoPerformance tool. To be interpreted by a computing system it is necessary to make such technique unambigu...

Automatic hydraulic press is one of the key Ceramic machinery and equipments for pressing ceramic wall and floor tiles, and its frame withstands all of the work force when it works, so the work performances of the frame have an important impact on the structural performance of the entire automatic hydraulic press. Took the frame of 32.8MN automatic hydraulic press as research object, establishe...

The chapter presents a general view of parallel meta-heuristics for optimization. It recalls the main concepts and strategies in designing parallel meta-heuristics and identifies trends and promising research directions. The focus is on cooperation-based strategies, which display remarkable performances, in particular strategies based on asynchronous exchanges and the creation of new informatio...

Software performance engineering deals with the consideration of quantitative analysis of the behaviour of software systems from the early development phases in the life cycle. This paper summarizes in a semiformal and illustrative way our proposal for a suitable software performance engineering process. We try to integrate in a very pragmatic approach the usual object oriented methodology —sup...

Software Performance Engineering is receiving increasing attention in today’s software dominated world. Compared to research work in performance evaluation in hardware and networks, this field is still in its nascent stage. Many methods have been proposed but majority of them are unable to adapt in the software development life-cycle dominated by professionals without substantial performance en...

This extended abstract summarizes our article on extracting probabilistic workload specifications for load testing and performance prediction of session-based application systems, which has been published recently in the Journal on Software and Systems Modeling [Vö16].

Analogical modeling is a supervised exemplar-based approach that has been widely applied to predict linguistic behavior. The paradigm has been well documented in the linguistics and cognition literature, but is less well known to the machine learning community. This paper sets out some of the basics of the approach, including a simplified example of the fundamental algorithm’s operation. It the...
