A key criterion in the design, procurement and use of computer systems is performance. Performance typically means the throughput and response time of a system. The effects of poorly performing systems range from dissatisfied users to high penalties for companies due to missed processing deadlines. As a result of continuously increasing hardware performance, companies often solve performance pr...

The goal of this research is to develop a generic framework for automatic configuration optimization of big data processing systems. The framework will allow users to specify their performance goals as well as their own metrics. We plan on utilizing system developer provided hints for searching suitable configurations for big data application deployments. Introduction Big data processing system...

For the better part of the 20 th century many large companies have been focussed on optimizing their mass production process as a way of maximizing their profits. Nowadays, in the existing environment of global competitiveness, enhancing the production process remains a significant issue as well. Product configuration based on integrated modular product structure and product family architecture...

Increasing interest for configuration similarity is currently developing in the context of Digital Libraries, Spatial Databases and Geographical Information Systems. The corresponding queries retrieve all database configurations that match an input description (e.g., "find all configurations where an object x0 is about 5km northeast of another x1, which, in turn, is inside object x2"). This pap...

In this paper we present an analysis that indentifies opportunities of introducing parallelism in the calculation of the configuration space. When the Convolution Theorem is used for this evaluation, two levels have appeared within the basic operation of the algorithms and another one for the employed computational tool (Fast Fourier Transform, FFT). The method has been applied to robots moving...

The importance of small urban parks (SUP) in mega cities has been accepted as an essential component of urban lung and restorative settings. As urban population in the world increases and the cost of maintaining large parks escalates, urban authorities are shifting their attention to creating and maintaining smaller urban parks. However, SUP may present a different ambience due to their locatio...
