The twenty-first century is the era of information technology, route planning play an important role in the field of navigation. An improved algorithm for route planning based on A∗ algorithm is presented in this paper. A certain number of turning points for route planning are set firstly by sorting out and analyzing the s-57 charts ENC data. Secondly, a database is established to store route points...
We provide a cloud-based journey planner for public transport built upon an efficient core routing engine that updates efficiently timetable information in case of delays. We describe our mobile application along with a service that allows users to assess the suggested journeys offered by the application, built on top of an IoT/FIRE+ infrastructure. Our journey planner contributes to the establishment...
Quality-aware service composition starts from an abstract workflow. The tasks of the workflow are associated with functional types for which concrete services can be retrieved from a registry. Abstract tasks have to be mapped to concrete services before the workflow is executed. The goal is to maximize the workflow quality by choosing the right combination of services. Spending more time in discovery...
Autonomous systems are often needed to perform tasks in complex and dynamic environments. For this class of systems, traditional safety assuring methods are not satisfying due to the unknown effects of the interacting system with an open environment. Briefly speaking: What is not known during the development phase, can not be adequately considered. In order to realize a more flexible safety analysis,...
Vehicle fuel consumption and emissions are directly related to the acceleration/deceleration patterns and the idling period. In order to reduce emissions and improve fuel economy, sharp acceleration/deceleration and idling should be avoided as much as possible. Unlike on freeways, traffic on signalized corridors suffers from increased fuel consumption and emissions due to idling and acceleration/deceleration...
This paper presents a dynamic composer for Web services. The services are enriched with semantic descriptions in OWL-S, based on which the composer automatically creates a combination of services reaching a specified goal. As an example, a trip planning use case is chosen where the goal ranges from booking of a single flight to planning of an entire trip including flight, hotel, transport, etc. The...
The importance of the deformation and physics based deformation methods are continuously increasing in computer graphics area. However, the user interaction and reality using them is still insufficient for the various applications such as modeling process and game industry. In this paper, we propose physics based deformation technology under AR (augmented reality) environments to improve the effectiveness...
Building on the extensive research in Virtual Reality (VR), we are proposing a new dynamic prototype for modelling and simulating carbon emissions in a virtual village called VIRVIL. VIRVIL is a simulated settlement for the assessment of the impact of low and zero carbon technologies and measures in the built environment. The prototype will focus on the impact on the community as a whole, as well...
