Method for generating a vector codebook, method and device for compressing data, and distributed speech recognition system

Abstract: A method for compressing data, said data being represented by an input vector having Q features, wherein Q is an integer higher than 1, the method for compressing data comprising the steps of 1) providing a vector codebook comprising sub-sets of indexed Q-feature reference vectors and threshold values associated with said sub-sets for a prefixed feature; 2) identifying a sub-set of reference vectors among said sub-sets by progressively comparing the value of a feature of the input vector - which corresponds to said prefixed feature - with the threshold values associated with said--sub-sets; 3) identifying the reference vector which - within the sub-set identified in step 2) - provides the lowest distortion with respect to the input vector.

Using Information Centric Networking for Mobile Devices Cooperation at the Network Edge

Abstract: This paper presents an Android application exploiting a collaborative multi-RAT approach (cellular and Wi-Fi Radio Access Technologies) for adaptively streaming video content. The application has been developed and tested on real Android devices of different vendors. Each device coordinates with the others to download portions of a video stream through its own preferred RAT, and shares the results with the neighboring devices through a proximity, high bit rate network based on Wi-Fi Direct. As a result, the aggregate bandwidth available to the group of collaborating devices allows a faster download and a higher quality of video playback streaming, with respect to what is achievable by a single device. The application is designed to exploit common Android devices along with the key functionalities of an Information Centric Network: routing-by-name, in-network caching and multicasting.

The Network is the Robot

Abstract: Ultra-broadband diffusion, information technology (IT) advances and the market mass decreasing costs are determining a growing adoption of processing and storage resources at the edge of current telecom networks that, ultimately, are the end-users. The number of devices connected to the network is growing at an exponential rate: embedded communications are everywhere. "Machine intelligence" is rapidly migrating towards the end-user, determining a number of socio-economic implications. Smart cities are going to become populated by any sort of mobile terminals, devices, machines, smart things, sensors, actuators, drones, robots etc. In general, ICT will basically become accessible to enterprises in any part of the world on an (almost) equal basis. In turn, this will reduce the thresholds for new players to enter the ICT services markets, moving the competition towards Opex-based models. This tendency is progressively accelerating and, from a socio-economic perspective, it is going to determine a transition from our society and the economy of resources towards the digital society and the digital economy. In this evolutionary scenario, telecommunications services are likely to be packaged with other services, and new services paradigms will be exploited: as an example, this paper proposes the model "anything-as-a-service", where any devices, machines, smart things, robots, drones, etc. will look like edge intelligent nodes providing the end-users with "any services". This transformation will require an highly flexible and pervasive 5G network, embedding processing and storage and providing high bandwidth, ultra-low latency links so as to create, literally, an innovative "nervous system" for the digital society. Eventually, this evolution will be capable of modernizing urban services such as transport, energy, water, food, education and will create new business opportunity, by integrating, systemically, 5G, big data and robotics.

Method and system for remote card access, computer program product therefor

Abstract: A method for providing an application access to a smart card (SC) includes the steps of: providing a card reader device (10) for receiving the smart card, providing a computer (12) for running the application (121), the computer (12) being equipped with a first portion (122a) of a smart card middleware for interfacing the card reader device (10), associating with the card reader device (10) a processing unit (16) incorporating a second portion (122b) of smart card middleware, and providing a network (N2) ensuring communication between the first portion (122a) and the second portion (122b) of the smart card middleware, thereby permitting access to the smart card (10) by the application (121).

Powerline effects over VDSL2 performances

Abstract: Telecom operator are using powerline technology (PLC or PLT) inside home as a "no new wire" solution to deliver video service (IPTV) from the home gateway (HG) to the set top box (STB). VDSL2 access technology will be used in next generation networks (NGN2) as final drop for residential customer. Both powerline and VDSL2 use the same frequencies to work: in this paper we present the measured effect of powerline on the VDSL2 technology in order to predict the expected performances.
