Financial intelligent monitoring system is emerging new research area and also has great commercial potentials. Traditional technical analysis relies on some statistics including technical indicators to determine turning point of the... more
During the past decade, the Financial Services industry has been transformed though the applications of computer-based analytics for forecasting, product design, portfolio optimization, risk management and intelligent advisory systems.... more
The need for intelligent monitoring systems for financial markets especially Foreign Exchange has become a necessity to keep track of this market. Financial markets conform to some mathematical concepts and cause it to be analyzed with... more
In this paper we present an approach for high-level behavior recognition and selection integrated with a low-level controller to help the robot to learn new skills from demonstrations. By means of Semantic Network as the core of the... more
Most of the humans day to day tasks include sequences of actions that lead to a desired goal. In domains which humans are replaced by robots, the ability of learning new skills easy and fast plays an important role. The aim of this... more
This paper integrates and applies established findings from previous research into peer collaboration to a realistic classroom situation in Swedish upper elementary school. The aim is to survey the research literature and to replicate... more
This thesis presents the notion of virtual com-munication as communication in which one or more parties deviates so strongly from the per-ceived interlocutor that the communication be-comes untrue to reality in some respects. Vir-tual... more
Abstract This contribution presents our experiences from developing an advanced course in grid computing, aimed at application and infrastructure developers. The course was intended for computer science students with extensive programming... more
We present a generic and light-weight Grid workflow execution engine made available as a Grid service. A long-term goal is to facilitate the rapid development of application-oriented end-user workflow tools, while providing a high degree... more
Abstract—The cloud computing landscape has recently developed into a spectrum of cloud architectures, leading to a broad range of management tools for similar operations but specialized for certain deployment scenarios. This both hinders... more
Abstract The emergence of Grid computing infrastructures enables researchers to share resources and collaborate in more efficient ways than before, despite belonging to different organizations and being geographically distributed. While... more
Utility computing, a concept envisioned back in the 1960s, is finally becoming a reality. Just as we can power a variety of devices, ranging from a simple light bulb to complex machinery, by plugging them into the wall, today we can... more
A resource broker is a central component in a grid environment. The purpose of the broker is to dynamically find, characterize and allocate the resources most suitable to the user's applications. This thesis describes the development of a... more
Abstract The emergence of Grid computing infrastructures enables researchers to share resources and collaborate in more efficient ways than before, despite belonging to different organizations and being distanced geographically. While the... more
