With the universal application of camera in intelligent vehicles, visual place recognition has become a major problem in intelligent vehicle localization. The traditional solution is to make visual description of place images using hand-crafted feature for matching places, but this description method is not very good for extreme variability, especially for seasonal transformation. In this paper, we propose a new method based on convolutional neural network (CNN), by putting images into the pre-trained network model to get automatically learned image descriptors, and through some operations of pooling, fusion and binarization to optimize them, then the similarity result of place recognition is presented with the Hamming distance of the place sequence. In the experimental part, we compare our method with some state-of-the-art algorithms, FABMAP, ABLE-M and SeqSLAM, to illustrate its advantages. The experimental results show that our method based on CNN achieves better performance than other methods on the representative public datasets.

In the last years, Virtual Reality (VR) has been established itself as a highly promising media technology for reconstruction and presentation of cultural heritage sites to a wide audience. Virtual Reality enables not only an exploration of a single artefact but of many virtual objects spatially and temporally arranged into a single scene. The users enter an artificially created space and get a feeling of being a part of it. They can perceive and interact with the objects in the virtual environment in natural way. In this paper we propose a conceptual model of the VR module for the “Virtual Plaza for Immersive Representation of Bulgarian Cultural Heritage Sites”. It contains an analysis of the possible input data and the developed workflows to help experts from the cultural heritage domain to implement various scenarios for presentation of single artefacts and complete scene par of cultural heritage site using the benefits of Virtual Reality as visualization medium.

Many network-wide traffic management strategies based on the Macroscopic or Network Fundamental Diagram (NFD) have been developed in recent years. In this paper we investigate one of these strategies, namely feedback NFD-based perimeter control, which limits the rate at which vehicles are allowed to enter an urban region. The inflow limitation is imposed at selected main entry links (gated links) and results in queuing of vehicles at the boundaries of the network. Most of the works on this subject neglected the effect of the queued vehicles on the traffic conditions upstream of the gated links. In this paper we analyze in microsimulation the queuing at the gated links and its effect on network performance for a realistic network model. Moreover, a queue management strategy based on a continuous quadratic knapsack problem aiming at balancing relative queues at the gated links is proposed. Simulation results suggest that queues under perimeter control are shorter in space and time than with no perimeter control. Additionally, managing the queues at the gated links not only improves the overall network performance but also reduces the possibility of queue propagation to the upstream junctions. This improves traffic flow outside the protected network.

Day by day, producers of manufacturing systems are challenged with the need of flexibility and reconfigurability of their products. Being able of rapidly provide various configurations of products in response to customers requests is an important asset in the nowadays competition. Nevertheless, most of the automation software for special machines is built in a monolithic way which does not support rapid reconfigurability to reflect hardware modifications. This paper proposes a modular and reconfigurable approach to software development for the automation to support rapid reconfigurations of the software. The designed strategy consists in a seamless replication of the hardware modularization within the software to allow software generation by assembling pre-built pieces of software. The approach is presented and then applied to a real manufacturing machine. © 2015 IEEE.

In the globally competitive market landscape, companies, in order to remain sustainable, must shift their focus towards constantly improving their PSS offerings by incorporating lean thinking approaches. PSS are complex, dynamic, and multi-dimensional systems, which are supported by appropriate infrastructure and networks. At the same time, PSS require robust engineering methods and tools for their design, which allow multi-dimensional exchange of knowledge between the designers and the relevant stakeholders across the value chain. Currently, enabling technologies such as Cloud technology, social media and networking, knowledge management, and context sensitivity present new possibilities to enhance the knowledge exchange and the collaborative process of PSS design. These technologies allow the gathering and analysis of big volumes of data from scattered heterogeneous IT systems and, at the same time, allow PSS design improvements by processing the experiences of the business customers, consumers, designers, shop-floor, and provide feedback to the design phase. However, a number of challenges are encountered during the gathering, visualization, monitoring, and assessment of related data, such as the lack of context sensitivity. Simultaneously, PSS evaluation approaches are still immature and there is limited work that correlates the impact of the entire PSS lifecycle with the performance assessment of the PSS design. The present work includes a review of the aforementioned technologies from academic, market, and industrial perspectives. Based on an extensive literature review and on constructive discussions with three European SMEs, several barriers and limitations of adopting the aforementioned technologies in practice are identified. Finally, a conceptual eco-innovative framework for lean PSS design is presented, explaining how these technologies could be combined for the improvements of PSS design and evaluation procedures.

The increasing of globalization requires companies to ship their machines all over the world. This growth of exportation of manufacturing systems increased costs of maintenance due to the requirement of sending technicians to the production site where the machine is installed. The strong spread of mobile devices and the increased quality of networks opened new horizons for maintenance and support services. The work presented in this paper describes a real application case and proposes an approach for using mobile internet devices (MID) on the production site for acquisition and transmission of multi-source information that can be used from service personnel to try to resolve issues from the vendor service center. The purpose of this article is to present an approach to implement a remote maintenance system based on a mobile platform that allows hybrid (video and telemetry) logging. © 2015 IEEE.

This paper introduces a new concept for flexible motion planning and control of industrial robots. Instead of a closed monolithic architecture, an open service-based framework is proposed. The services can be run hardware-independent on a decentralized IT infrastructure (Cloud) allowing a fast reconfiguration of control modules and their multiple usage in different tasks. The services can be run on a dedicated PC or on individual virtual machines inside a single computing cluster. The proposed service-based framework was implemented and tested for the motion planning of a robotic manipulator. Effects on control performance, availability and scalability are investigated and documented. © 2015 IEEE.

Modern companies face immense market pressure to meet customers’ demands while ensuring the sustainability of business. Consumers are now requesting highly customized products and services, i.e. demanding mass customization from manufacturing companies. The complete value chain needs to develop strategies enabling interaction with customers and consumers, supporting customization of features and services, and even co-design. This paper presents the DIVERSITY approach, which consists on a methodology and engineering environment supporting companies in using social media to realize a context sensitive lean design process of product service systems.
