Method and system for selecting data items for service requests

Abstract: A method and system locate a transponder that has an associated identifier and content data, at a location substantially accessible to a user of the mobile terminal. The transponder is activated by the mobile terminal with a wireless signal. In response, the mobile terminal receives at least the identifier and the content data from the activated transponder at the mobile terminal. From the received identifier and/or content data, the method and system select one or more of the stored data items according to one or more criteria.

State-of-the-art and good practice in the field of living labs

Abstract: Living Labs are an emerging Public Private Partnership (PPP) concept in which firms, public authorities and citizens work together to create, prototype, validate and test new services, businesses, markets and technologies in real-life contexts, such as cities, city regions, rural areas and collaborative virtual networks between public and private players. The real-life and everyday life contexts will both stimulate and challenge research and development as public authorities and citizens will not only participate in, but also contribute to the whole innovation process. This paper examines the state-of-the art in involving the user and stakeholder organisations into the innovation process in various ongoing, embryonic Living Labs initiatives, examines the key practices that need to be in place for the maturation of the concept and gives examples on how those are currently being deployed. The paper concludes with a section dedicated to identifying areas in which future research is required.

Gaussian KD-trees for fast high-dimensional filtering

Abstract: We propose a method for accelerating a broad class of non-linear filters that includes the bilateral, non-local means, and other related filters. These filters can all be expressed in a similar way: First, assign each value to be filtered a position in some vector space. Then, replace every value with a weighted linear combination of all values, with weights determined by a Gaussian function of distance between the positions. If the values are pixel colors and the positions are (x, y) coordinates, this describes a Gaussian blur. If the positions are instead (x, y, r, g, b) coordinates in a five-dimensional space-color volume, this describes a bilateral filter. If we instead set the positions to local patches of color around the associated pixel, this describes non-local means. We describe a Monte-Carlo kd-tree sampling algorithm that efficiently computes any filter that can be expressed in this way, along with a GPU implementation of this technique. We use this algorithm to implement an accelerated bilateral filter that respects full 3D color distance; accelerated non-local means on single images, volumes, and unaligned bursts of images for denoising; and a fast adaptation of non-local means to geometry. If we have n values to filter, and each is assigned a position in a d-dimensional space, then our space complexity is O(dn) and our time complexity is O(dn log n), whereas existing methods are typically either exponential in d or quadratic in n.

Graphene-Based Integrated Photonics For Next-Generation Datacom And Telecom

Abstract: Graphene is an ideal material for optoelectronic applications. Its photonic properties give several advantages and complementarities over Si photonics. For example, graphene enables both electro-absorption and electro-refraction modulation with an electro-optical index change exceeding 10$^{-3}$. It can be used for optical add-drop multiplexing with voltage control, eliminating the current dissipation used for the thermal detuning of microresonators, and for thermoelectric-based ultrafast optical detectors that generate a voltage without transimpedance amplifiers. Here, we present our vision for grapheme-based integrated photonics. We review graphene-based transceivers and compare them with existing technologies. Strategies for improving power consumption, manufacturability and wafer-scale integration are addressed. We outline a roadmap of the technological requirements to meet the demands of the datacom and telecom markets. We show that graphene based integrated photonics could enable ultrahigh spatial bandwidth density , low power consumption for board connectivity and connectivity between data centres, access networks and metropolitan, core, regional and long-haul optical communications.
