Assessing software quality attributes is one of the most sought-after topics in recent software engineering research literature. Performance characteristics of the software systems, responsiveness and scalability in particular, are of the most important attributes determining the software quality. The ability to assess the software performance as early as possible in the software life cycle is ...

improving individual performance is one of the most influential requirements of sustainable productivity and competitiveness of organizations. this research is investigate the influence of spiritual intelligence on the individual performance in accordance with creativity, innovation and mental health as mediators. the research method used is quantitative, applied and descriptive. the population...

Computational expressive music performance studies the analysis and characterisation of the deviations that a musician introduces when performing a musical piece. It has been studied in a classical context where timing and dynamic deviations are modeled using machine learning techniques. In jazz music, work has been done previously on the study of ornament prediction in guitar performance, as w...

Performance models of applications enable HPC system designers and centers to gain insight into the most optimal hardware for their applications, giving them valuable information into the components of hardware (for example processors or network) that for a certain investment of time/money will give the most bene t for the applications slated to run on the new system. The task of developing acc...

Both coaches and cyclists nowadays determine the training schedules for important races based on experience and gut-feeling. Data are available for the evaluation of training schedules, but a sound scientific method of accomplishing this does not yet exist. The biggest hurdle in developing such a method for cycling is the absence of an objective performance metric. This report uses the data of ...

In this chapter, we collect actual CPU time measurements of a number of prototypical PDE simulators for solving the Poisson equation, the linear elasticity equation, the heat conduction equation, the equations of nonlinear water waves, the incompressible Navier-Stokes equations, and many more. We show how these measurements can be used to establish performance models of the form: t = C n, which...

Full scale measurements of the propulsion power, ship speed, wind speed and direction, sea and air temperature, from four different loading conditions has been used to train a neural network for prediction of propulsion power. The network was able to predict the propulsion power with accuracy between 0.8-2.8%, which is about the same accuracy as for the measurements. The methods developed are i...

Software construction with reusable components and legacy code has proven useful for fast and low-cost software development in many real world applications. However, since this methodology is often applied to domains with stringent performance and resource constraints such as embedded systems, its ignorance of non-functional constraints makes it very difficult and expensive to meet the constrai...

The proliferation of mobile wireless computing devices and the increasing usage of wireless networking have motivated substantial research in mobile ad hoc networks (MANETs). In addition, much has also been done to link autonomous MANETs to the Internet, and as MANETs become more prevalent, the need to interconnect multiple MANETs becomes increasingly important too. However, direct interconnect...
