New sensor, communication and software technologies are used to broaden the facilities of tracing and tracing systems for food transports. An embedded assessing unit detects from sensor data collected by a wireless network potential risks for the freight quality. The estimation of the current maturing state of agricultural products will be supported by(More)
In this paper, we investigate possibilities and limitations of temperature change as a method for information display in mobile applications. While some widespread and well-recognized haptic displays such as force-feedback often trigger the user's immediate attention, we will focus on ambient strategies for tactile information display, that is, the display(More)
Scenario setting The previous chapters described the application of autonomous cooperation on embedded systems, in sensor networks, transport planning and communication systems. For practical demonstration of the implications of the described studies the prototype of the intelligent container was linked to an agent system for transport coordination(More)
In the mouse retina, three different types of photoreceptors provide input to 14 bipolar cell (BC) types. Classically, most BC types are thought to contact all cones within their dendritic field; ON-BCs would contact cones exclusively via so-called invaginating synapses, while OFF-BCs would form basal synapses. By mining publically available electron(More)
In this demonstration a research prototype for autonomous local control of logistic processes in the transportation domain is presented. The aim of autonomy in logistics is to gain flexibility and robust-ness in process execution as well as increasing promptness and reducing human efforts in the coordination of a logistic process. This is enabled by(More)
Large-scale recordings of neuronal activity make it possible to gain insights into the collective activity of neural ensembles. It has been hypothesized that neural populations might be optimized to operate at a 'thermodynamic critical point', and that this property has implications for information processing. Support for this notion has come from a series(More)
platform for secure communication in wireless sensor networks for logistic applications. Abstract In this paper we present a new methodology for the integration of security provisions into protocols for wireless sensor networks. There is an ever growing demand for security in communications in general. As wireless sensor networks (WSN) face real-world(More)
This paper describes a novel solution for authenticated key agreement for wireless sensor networks (WSN) in logistics. The retrieved data may not be spoofed as it is used to generate information about the quality of the freight, especially for sensitive freight like food. Instead of relying on pre-configuration, every sensor node is authenticated(More)
This poster shows the work-in-progress results of an effective method for predicting the residual battery energy in WSN nodes including the battery behavior. This method uses a hybrid approach consisting of a deterministic part by counting credit points for any operation of the sensor node and a model-based State-of-Charge (SoC) estimation based on battery(More)
