Noise signals are often encountered in several science and engineering fields. They can be originated by a lot of different mechanisms, some of which are still not sufficiently understood. Since reliability and performance of many systems dep.nd on their noise sensitivity and noise rejection capability, suitable noise sources are required to lead appropriate tests to investigate the behavior of the same systems in the presence of noise. At present, only white noise sources are available on the market. Technicians that need to generate colored noise could use arbitrary waveform generators as noise sources;but, they will barely find application notes that support them in this challenging task. This work presents tutorial notes related to the simulation of colored noise, in particular of composite-power-law noise, and proposes an analog generator that exploits an arbitrary waveform generator as noise source.

Biophotonic imaging can be used to characterize tumor growth in animal models. Estimation of the numbers and location of target cells is dep.ndent on accurate segmentation of a target region from the background luminescence of the animal body. Existing software systems extract general regions of interest in complex images but can fail to detect details or faint regions of interest in the presence of higher luminescent activity. Limited work has been published in the analysis of these images. We explore the use of popular medical image segmentation techniques in segmentation of bioluminescence images. The ability of each algorithm in detecting regions of interest is tested using established performance measures. Based on the characteristics of bioluminescence images of animal tumor models, and the performance of the algorithms, we formulate a framework for segmentation techniques best suited for this application.

This paper discusses different formal models to represent educational processes and their use by computer systems. Currently most of these models are tied to specific application scenarios and tools, which reduces the transferability and re-usability of these models in different contexts. To achieve the interoperable use and transfer between different educational systems we propose the meta-modeling approach GOLEM (Graphically Organized Learning and Educational Metamodel) using an intermediary visual language the different models are mapped to. We describe the different mappings and discuss potential and limitations of the transformations.
In this paper, equations of motion of a manipulator, whose mechanism has a passive revolute joint, are derived in consideration of characteristics of driving source. Considering the final condition about displacement ...

Quality of Service (QoS) is a central characteristic of human-centric Ambient Intelligence (Ami) systems, since it has a strong relation to the degree of satisfaction with the services provided to users. Hence, Ami applications must be able to describe their QoS needs as well as capabilities so that the corresponding infrastructures can match the latter to the preferences of users. Current QoS specification techniques are concentrated on special domains like communication systems and do not address special aspects of the Ami field like high dynamics. In this paper we, elaborate the special Ami requirements posed to QoS specifications and describe an initial approach towards a solution.

In this paper, we present a large-scale interactive book browsing installation for children's libraries called StorySurfer. The StorySurfer prototype is developed within the Interactive Children's Library project, which includes interests from within design, research, industry, and libraries. The objective of the project is to give room for and encourage the physical activities of children, while pursuing to connect these with the basic digital and analogue services of the library e.g. borrowing and handing in books, searching for information, and providing access to a rich variety of media.
