Due to the Industrial Internet of Things and rising complexity of intelligent technical systems efficient design and test processes for mechanical and plant engineering become more important. The design and test process encompasses the discipline-spanning system design in early phases, virtual prototyping as well as virtual commissioning in test phases. This contribution illustrates a holistic model-based...
A method is shown to estimate the position of a (single) radiation source fusing the data from a sodium iodide detector and a gyroscope while panning the detector. Based on geometry considerations, the search motion of a detector is modelled as angular panning and waving motions. Correlation of the sensor data stream from the an gyroscopical accelerometer with the count rate event data of the detector...
Scattering and attenuation have significant impact on the spectrum. For submersible nuclide identification devices, it is mandatory to still provide high quality identification results, even if the instrument is in the water. A technique is shown, to treat the effects of water scattering. This is done by combining the so-called dynamic derivative convolution method and a maximum-likelihood approach...
A stabilization concept based on a self-learning R-Tree index method is presented and demonstrated with measurements from a 1.5×1.5 cerium bromide detector. The concept uses a cognitive filter, a digital filter for nuclear signals that continuously updates itself to the current temperature by adjusting the filter components. The R-Tree combines the information from this cognitive filter together with...
A digital filter is presented that adapts automatically to the shape of a nuclear signal to stabilise against temperature induced peak shifting. The filter is called cognitive as it extracts the information about the exponential decays and determines the scintillation material intrinsically. The latter is done with a pole deconvolution approach.
In this paper, a distance vector routing algorithm for IP computer networks is presented which is able to aggregate routes automatically and detect and prevent routing loops even on the aggregated routes. Route aggregation is the method of summarizing two or more routes to the corresponding destination IP subnetwork addresses into one common IP prefix address. Thus, it enables non-hierarchical network...
The subject of the RailCab project is the development of autonomous railway cabins, which can dynamically group to convoys without mechanical coupling. This enables an on-demand use of these vehicles while retaining the cost and ecological advantages of public transport. In this paper, we present (1) the system concept with focus on the convoy operation mode. Furthermore we explain (2) the system...
Functional composition is an approach for a flexible network architecture which enables a customized combination of functionality with respect to application requirements. Functional composition overcomes the inflexibility of the current Internet architecture and facilitates the management of functionality within the network. Several projects have addressed this topic with different aspects, in this...
Network Functional Composition is an approach for a flexible Internet architecture which decomposes the layered network stack in functional building blocks which can be loosely coupled. Functional Composition therefore enables a customized composition of functionality at the edges and in the network in respect to application specific requirements. Functional Composition is an architecture for a Future...
Ambient Intelligence (AmI) is a vision of an environment with ubiquitous distributed devices embedded in everyday objects that are interconnected and seamlessly deliver applications and services. Based on concepts of ubiquitous computing, ubiquitous communication and intelligent interfaces, AmI puts the user in the center of future technological development. In this paper we consider human aspects...
