The new name “International Conference on Innovations for Community Services” (I4CS) has been successfully established in Reims, France last year. The I4CS is the direct follower of the “International Conference on Innovative Internet Community Systems” (I2CS), founded as a scientific workshop in 2001. Alternately, international and German locations are selected by the steering committee for the annual...
In a time where environmental protection is a big topic, use of electric vehicles is steadily increasing. Many people have reservations to use this new technology because of the limited range of electric vehicle. The range is influenced by many parameters like velocity, ramp, weight and so on. In respect of such facts prediction of range is a very important but difficult topic. One thinkable solution...
In Wireless Sensors Network (WSN) the energy parameter is important. The traffic management needs a clever scheduling algorithm that can balance the energy consumption and the time slots also can be divided according to the traffic pattern. Every sensor node collects the environmental data and sends it to the coordinator. Using scheduling algorithm allows the communication process to be done in a...
In this paper, we propose a monocular vision system for autonomous obstacle avoidance and simultaneous stabilization of dynamic bipedal walking using the Aldebaran Nao robot. In particular, we address the case where erroneous bipedal locomotion causes the robot to drift away from a planned trajectory over time. To eliminate drifting, we use hybrid control patterns. This results in an efficient, self-correcting...
A large-scale system hundreds of millions of people encounter every day is radio. While this “system” has a tremendous reach it also is technologically outdated. Technological constraints offer great protection of listeners’ privacy but prevent radio stations from implementing modern business models like personalization and mining valueable user information, at the same time. This paper describes...
Mobile sensing in Cyber-Physical Systems has been evolving proportionally with smartphones. In fact, we are witnessing a tremendous increase in systems that sense various facets of human beings and their surrounding environments. In particular, the detection of human emotions can lead to emotionally-aware applications that use this information to benefit people’s daily lives. This work presents the...
Approximately half a decade ago, the Bluetooth Low Energy standard was defined as extension of the initial Bluetooth communication concept. Although there is some similarity to the original definition, the low energy version works upon some fundamentally different RF coding principles and parameters. Bluetooth low energy can also serve for linking sports and health sensors to personal, ubiquitous...
Application development for highly dynamic and unpredictable scenarios still is a difficult and time-consuming task. This in particular is a problem in the area of robotics: if a certain task should be executed, many asynchronous events can prevent a plan from its termination. In contrast to applications in e.g. office scenarios, interruption as a result of unexpected conditions is the normal case...
The classification of web pages content is essential to many information retrieval tasks. In this paper, we propose a new methodology for a multilayer soft classification. Our approach is based on the connection between the semi-supervised Latent Dirichlet Allocation (LDA) and the Random Forest classifier. We compute with LDA the distribution of topics in each document and use the results to train...
How does a future centralized learning platform for students in an academic environment look like? What are the needs and requirements for current and potential academic users? Are Facebook, WhatsApp and Dropbox the winners? Which recommendations can be worked out for a suitable IT landscape and how does an integrated data security concept look like? This paper analyses the needs and requirements...
We provide a privacy-friendly cloud-based smart metering storage architecture which provides few-instance storage on encrypted measurements by at the same time allowing SQL queries on them. Our approach is most flexible with respect to two axes: on the one hand it allows to apply filtering rules on encrypted data with respect to various upcoming business cases; on the other hand it provides means...
In this work we describe the implementation details of a protocol suite for a secure and reliable over-the-air reprogramming of wireless restricted devices. Although, recently forward error correction codes aiming at a robust transmission over a noisy wireless medium have extensively been discussed and evaluated, we believe that the clear value of the contribution at hand is to share our experience...
CoSSMic (Collaborating Smart Solar powered Micro-grids) is an EU funded project. It aims to develop both hardware and software which will include an ICT system for smart management and control of generated/consumed solar energy in neighbourhood communities. The creation process of energy monitoring and controlling of Graphical User Interfaces (GUIs) is described here. User Centred Design Workshops...
With an ever-increasing amount of information made available via the Internet, it is getting more and more difficult to find the relevant pieces of information. Recommender systems have thus become an essential part of information technology. Although a lot of research has been devoted to this area, the factors influencing the quality of recommendations are not completely understood. This paper examines...
This paper reports on a feasibility study of a smartphone-based SOS system. Compared to other emergency systems the presented system: a) is independent from existing network infrastructure and b) runs on off-the-shelf devices. The presented system exploits Wi-Fi service set identifiers (SSIDs) for the discovery of phones and to convey short emergency messages. It can operate in two setups: either...
To enhance current earthquake early warning (EEW) systems, emerging technologies, including social and mobile computing, have been the focus of much attention. As smartphones have benefitted from significant development over the last few years, it is now possible to capture various kinds of motion using a smartphone’s sensors, (e.g., accelerometer, GPS, etc.) including earthquake motion. To that end,...
