Abstract

In this work, an intelligent human-machine interface (HMI) for human worker activity recognition in industrial environments is presented. The interface consists of components for robust and accurate 3D position estimation in workspace environments, the recognition of task-related worker activities and human-computer interaction via gestures. All components of the presented HMI are flexible with respect to applications and can be transferred to other activity recognition problems, as well.

Abstract

In der vorliegenden Abhandlung wird ein System zur autonomen 3D-Umweltmodellierung vorgestellt, welches auf den drei Hauptprozessen Datenaufnahme, Datenintegration und Aktionsplanung beruht. Basis der Modellierung sind dichte Tiefenbilder, generiert durch einen rotierenden Zeilenscanner, mit Punktmerkmalen. Durch die Registrierung aller Daten können die Fehler der odometrischen Lagebestimmung minimiert werden. Anhand der ermittelten 3D-Daten wird die nächste beste Aufnahmeposition ermittelt.

Abstract

Wirbelstrom-Sensoren ermöglichen die Realisierung einer rein bordautonomen Ortung von Schienenfahrzeugen. Diese basiert dabei auf zwei diversitären Verfahren. Zum einen wird die Geschwindigkeit berührungslos gemessen, zum anderen lassen sich Weichen und Weichenbauteile detektieren und mit einem Bayes-Klassifikator klassifizieren. Gestützt mit einem Hidden-Markov-Modell (HMM) zur Modellierung der Infrastruktur lässt sich eine absolute Position bestimmen und somit ein Ortungssystem realisieren.

Abstract

The 2017 International Conference on Micro/Nanomachines (http://www.icmnm.org/) was held in Wuhan, China, 25–28 August, 2017. Micro/nanomotors (MNMs), which are defined as micro/nanodevices capable of converting energy into autonomous motion, can be used to pick up, transport, and release various cargoes within a liquid medium. They have important potential applications, for example, in drug delivery, biosensors, protein and cell separation, microsurgeries, and environment remediation. MNMs can be classified into two categories, according to their propulsion mechanism. In this respect, self-propelled MNMs are capable of moving autonomously without external intervention, but they either require toxic fuel or have a short lifespan. MNMs actuated by external fields, such as light, magnetic field, and acoustic waves, are not subject to these problems, do not require toxic fuels, nor give rise to by-products during the motion process. For both self-propelled and field-actuated MNMs, there is still a long way to go before we reach practical applications. The future development of MNMs should be focused on improving the energy conversion efficiency through structure optimization, exploring new propulsion mechanisms and endowing MNMs with environmental responses for self-navigation, detection, and specific operations. In this way, MNMs will approach their practical application in biomedicine, environment treatment, microengineering, etc.

Abstract

Image processing in agriculture and forestry represents a challenge towards the automation of tasks for better performances. Agronomists, computer and robotics engineers, and agricultural machinery industry manufacturers now have at their disposal a book containing a collection of methods, procedures, designs, and descriptions at the technological forefront, which serves as an important support and aid for the implementation and development of their own ideas.The book describes: (1) Applications (canopy on trees, aboveground biomass, phenotyping, chlorophyll, leaf area index, water and nutrient content, land cover change, soil properties, and secure autonomous navigation); (2) Imaging devices onboard robots, unmanned aerial vehicles (UAVs), and satellites operating at different spectral ranges (visible, infrared, hyper-multispectral bands, and radar), as well as guidelines for selecting machine vision systems in outdoor environments; and (3) (Specific computer vision methods (generic and convolutional neural networks, machine learning, specific segmentation approaches, vegetation indices, and three-dimensional (3D) reconstruction).

Abstract

The new concept for mobile environmental education extends the traditional media-based environmental interpretation by means of a mobile context-aware computer. This mobile nature guide system can assist its user during self-determined exploration by adapting its presentation to the usage situation, preferences and current environmental conditions. The impact of the prototype mobile nature guide on environmental literacy and user satisfaction has been compared to traditional media in the field.

Abstract

As the ultimate information processing device, the brain naturally lends itself to being studied with information theory. The application of information theory to neuroscience has spurred the development of principled theories of brain function, and has led to advances in the study of consciousness, as well as to the development of analytical techniques to crack the neural code—that is, to unveil the language used by neurons to encode and process information. In particular, advances in experimental techniques enabling the precise recording and manipulation of neural activity on a large scale now enable for the first time the precise formulation and the quantitative testing of hypotheses about how the brain encodes and transmits the information used for specific functions across areas. This Special Issue presents twelve original contributions on novel approaches in neuroscience using information theory, and on the development of new information theoretic results inspired by problems in neuroscience.
