In this work we present the decision support of the EMBalance platform. EMBalance is a platform for the management of balance disorders in terms of diagnosis, treatment and evolution. The EMBalance platform aims to extend existing but generic and currently uncoupled balance modelling activities leading to a multi-scale and patient-specific balance model, which will be incorporated in a Decision Support System (DSS), towards the early diagnosis, prediction and the efficient treatment planning of balance disorders. The diagnosis part of the decision support system uses various data ranging from demographic characteristics to clinical examinations, auditory and vestibular tests. Currently we present some initial technical choices and indicative results of the decision support system for diagnosing balance disorders, based on data mining techniques and clinical guidelines. © 2015 IEEE.

The transition from classic combustion engine vehicles to electric vehicles is a major step to reduce worldwide CO_2 emissions. In order to correctly and efficiently investigate impacts on the electric grid and the dimensioning of charging infrastructure, or to explore new technologies for a further increase of the driving range, realistic simulation models are required. In this paper, we present an accurate yet computationally inexpensive battery and kinematic model to be used in microscopic traffic simulation to help study the performance of thousands of electric vehicles. Our model also supports recuperation and range extender modules while only relying on the vehicle's speed and a set of constant predefined parameters. It can therefore be easily coupled with current sophisticated traffic simulators. We show its applicability and correctness regarding the State of Charge and power flows using comprehensive real-life experiments.

Inter-Vehicle communication (IVC), i.e., the ad hoc information exchange between vehicles, is believed to help increase traffic safety, improve traffic efficiency, and also increase the comfort of drivers. Often simulation is used to evaluate these applications. The fact that this becomes a challenging task in the context of privacy is one of the reasons that proper privacy protection is often disregarded [1]. The concept of privacy is very abstract, meaning it is difficult to quantify the level of privacy protection and find easy to understand metrics [2]. Also, in order to compare two different privacy protection mechanisms, the exact settings of the simulation have to be known. In vehicular network simulation, and more so in privacy simulation, results heavily depend on the used parameters and due to space limitations they are often not in the article presenting a privacy protection scheme [3]. To make matters worse, there is still no publicly available simulation environment, requiring each researcher to implement their own evaluation tools.

Attribute-based encryption (ABE), introduced by Sahai and Waters, is a promising cryptographic primitive, which has been widely applied to implement fine-grained access control system for encrypted data. In its key-policy flavor, attribute sets are used to annotate ciphertexts and secret keys are associated with access structures that specify which ciphertexts a user is entitled to decrypt. In most existing key-policy attribute-based encryption (KP-ABE) constructions, the size of the ciphertext is proportional to the number of attributes associated with it and the decryption cost is proportional to the number of attributes used during decryption. In this paper, we present a new construction of KP-ABE. Our proposed construction is the first KP-ABE scheme, which has the following features simultaneously: expressive (i.e., supporting arbitrary monotonic access structures);fully secure in the standard model;constant-size ciphertexts and fast decryption. The downside of our construction is that secret keys have quadratic size in the number of attributes. Copyright 2014 ACM.

Non-intrusive load monitoring (NILM) is a popular approach to estimate appliance-level electricity consumption from aggregate consumption data of households. Assessing the suitability of NILM algorithms to be used in real scenarios is however still cumbersome, mainly because there exists no standardized evaluation procedure for NILM algorithms and the availability of comprehensive electricity consumption data sets on which to run such a procedure is still limited. This paper contributes to the solution of this problem by: (1) outlining the key dimensions of the design space of NILM algorithms;(2) presenting a novel, comprehensive data set to evaluate the performance of NILM algorithms;(3) describing the design and implementation of a framework that significantly eases the evaluation of NILM algorithms using different data sets and parameter configurations;(4) demonstrating the use of the presented framework and data set through an extensive performance evaluation of four selected NILM algorithms. Both the presented data set and the evaluation framework are made publicly available.

The DeSyRe project builds on-demand adaptive, reliable systems-on-Chips. In response to the current semiconductor technology trends thatmake chips becoming less reliable, DeSyRe describes a newgeneration of by design reliable systems, at a reduced power and performance cost. This is achieved through the following main contributions. DeSyRe defines a fault-tolerant system architecture built out of unreliable components, rather than aiming at totally fault-free and hence more costly chips. In addition, DeSyRe systems are on-demand adaptive to various types and densities of faults, as well as to other system constraints and application requirements. For leveraging on-demand adaptation/customization and reliability at reduced cost, a new dynamically reconfigurable substrate is designed and combined with runtime system software support. The above define a generic and repeatable design framework, which is applied to two medical SoCs with high reliability constraints and diverse performance and power requirements. One of the main goals of the DeSyRe project is to increase the availability of SoC components in the presence of permanents faults, caused at manufacturing time or due to device aging. A mix of coarse- and fine-grain reconfigurable hardware substrate is designed to isolate and bypass faulty component parts. The flexibility provided by the DeSyRe reconfigurable substrate is exploited at runtime by system optimization heuristics,which decide tomodify component configurationwhen a permanent fault is detected, providing graceful degradation. © 2014 Springer International Publishing Switzerland.

Platooning, the idea of cars autonomously following their leaders to form a road train, has huge potentials to improve traffic flow efficiency and, most importantly, road traffic safety. Wireless communication is a fundamental building block - it is needed to manage and to maintain the platoons. To keep the system stable, strict constraints in terms of update frequency and reliability must be met. We developed communication strategies by explicitly taking into account the requirements of the controller, exploiting synchronized communication slots as well as transmit power adaptation. The proposed approaches are compared to two state of the art adaptive beaconing protocols that have been designed for generic message dissemination. Our simulation models have been parametrized and validated by means of real-world experiments. We clearly show how taking into account specific requirements can be extremely beneficial even in very crowded freeway scenarios.

Merging WBAN systems with cloud computing is an efficient solution to overcome limitations inherent in WBAN, especially in critical human-related applications such as remote health monitoring. In cloud-based WBAN, the nodes are classified into WBAN sensors that report measurements about the human body and WBAN actuators that receive commands from the medical staff and perform actions. Authenticating these commands is a critical security issue as any alteration may lead to serious consequences. This paper presents a light-weight public-key authentication protocol for cloud-based WBAN systems. The proposed protocol is based on the modified Rabin authentication algorithm which is customized in this paper by making some of its components run in parallel. To prove the efficiency of the modified Rabin we implemented the algorithm with different hardware settings using Tmote Sky motes. The Rabin algorithm with and without the parallel settings is also programmed on FPGA to evaluate its design and performance. The results show that secure, direct, instant, and authenticated commands can be delivered from the medical staff located at the cloud side to the WBAN nodes located in/on the human body. Compared to other public-key protocols implemented on the motes, Rabin algorithm achieved extremely faster verification and reasonable signature gen- eration speed. Moreover, the suggested parallel settings of the Rabin signature generation significantly reduced the delays( by almost 80%) which is a critical issue in WBAN applications. Copyright © 2014 ICST.
