Addiction is a compulsive need for and use of a specific substance leading to a habit, tolerance, and psychophysiological symptoms. Excessive food consumption is similar to that of substance addiction. Some individuals who have trouble losing weight display addictive eating symptoms. To investigate food addiction in a sample of obese adults referred to hospital for a 1-month-weight-loss treatment. The Italian version of the Yale Food Addiction Scale (YFAS-16) was used as a screening tool in 88 obese inpatients. The construct validity of the YFAS-16 was assessed by testing its correlations with measures of binge eating (Binge Eating Scale), impulsiveness (Barratt Impulsiveness Scale), and emotional dysregulation (Difficulties in Emotion Regulation Scale). 34.1% of our sample was diagnosed with YFAS food addiction. Such diagnosis was also supported by strong associations between FA and psychological and behavioral features, typically descriptive of classic addiction. Patients who endorsed the YFAS-16 criteria for food addiction (FA) had significantly higher binge eating levels, greater emotional dysregulation, and nonacceptance of negative feelings; they lacked goal-oriented behavior, had little impulse control, had difficulty in emotion recognition, and attentional impulsivity; and they were unable to concentrate and lacked inhibitory control behavior, unlike participants who did not meet the FA criteria. Further research is needed to support the reliability of the YFAS-16. This measure has the potential to be applied in epidemiological research, estimating the prevalence of FA within the Italian population and to assess new treatments’ efficacy for obese patients with food addiction symptoms seeking weight-loss treatments.
Mitigating the Impact of Mobility on H.264 Real-Time Video Streams Using Multiple Paths
Calafate, Carlos T.,Malumbres, Manuel P.,Manzoni, Pietro The Korea Institute of Information and Commucation 2004 Journal of communications and networks Vol.6 No.4
One of the main problems associated with MANETs is that mobility and the associated route discovery and maintenance procedures of reactive routing protocols cause severe interruptions on real-time video streams. Some of these interruptions are too large to be concealed using any sort of video technology, resulting in communications breaks unpleasant for the final end user. We present a solution for enhanced video transmission that increases route stability by using an improved route discovery process based on the DSR routing protocol, along with traffic splitting algorithms and a preventive route discovery mechanism. We also present some video adaptative mechanisms that improve the overall performance of multipath routing in terms of video data replication and video packet splitting strategies. Combining our proposals, we achieve up to 97% less interruptions on communication with high mobility and over 1.2 dB of improvements in terms of video distortion.
Design and Validation of a Low-Power Network Node for Pervasive Applications
Juan-Carlos Cano,Carlos T. Calafate,Pietro Manzoni,Jose-Manuel Cano,Eva Gonzalez 보안공학연구지원센터 2008 International Journal of Software Engineering and Vol.2 No.1
Pervasive computing refers to making many computing devices available throughout the physical environment, while making them effectively invisible to the user. To further increase the applicability of ubiquitous computing, minimizing energy consumption and hardware cost are mandatory in real world applications. In this paper we present our platform prototype for ubiquitous computing, which has been implemented based on commercial Bluetooth off-theshelf components. It allows every object to be augmented with processing and communication capabilities in order to make them "smart". We validate our proposal by evaluating the tradeoff between power consumption and performance for our experimental prototype. Our prototype has been used in a museum application to support ubiquitous computing between devices without requiring a priori knowledge of each other.
SEISMIC ISOLATION OF LEAD-COOLED REACTORS: THE EUROPEAN PROJECT SILER
Forni, Massimo,Poggianti, Alessandro,Scipinotti, Riccardo,Dusi, Alberto,Manzoni, Elena Korean Nuclear Society 2014 Nuclear Engineering and Technology Vol.46 No.5
SILER (Seismic-Initiated event risk mitigation in LEad-cooled Reactors) is a Collaborative Project, partially funded by the European Commission in the $7^{th}$ Framework Programme, aimed at studying the risk associated to seismic-initiated events in Generation IV Heavy Liquid Metal reactors, and developing adequate protection measures. The project started in October 2011, and will run for a duration of three years. The attention of SILER is focused on the evaluation of the effects of earthquakes, with particular regards to beyond-design seismic events, and to the identification of mitigation strategies, acting both on structures and components design. Special efforts are devoted to the development of seismic isolation devices and related interface components. Two reference designs, at the state of development available at the beginning of the project and coming from the $6^{th}$ Framework Programme, have been considered: ELSY (European Lead Fast Reactor) for the Lead Fast Reactors (LFR), and MYRRHA (Multi-purpose hYbrid Research Reactor for High-tech Applications) for the Accelerator-Driven Systems (ADS). This paper describes the main activities and results obtained so far, paying particular attention to the development of seismic isolators, and the interface components which must be installed between the isolated reactor building and the non-isolated parts of the plant, such as the pipe expansion joints and the joint-cover of the seismic gap.
RCDP: Raptor-Based Content Delivery Protocol for Unicast Communication in Wireless Networks for ITS
Baguena, Miguel,Toh, C.K.,Calafate, Carlos T.,Cano, Juan-Carlos,Manzoni, Pietro The Korea Institute of Information and Commucation 2013 Journal of communications and networks Vol.15 No.2
Recent advances in forward error correction (FEC) coding techniques were focused on addressing the challenges of multicast and broadcast delivery. However, FEC approaches can also be used for unicast content delivery in order to solve transmission control protocol issues found in wireless networks. In this paper, we exploit the error resilient properties of Raptor codes by proposing Raptor-based content delivery protocol (RCDP) - a novel solution for reliable and bidirectional unicast communication in lossy links that can improve content delivery in situations where the wireless network is the bottleneck. RCDP has been designed, validated, optimized, and its performance has been analyzed in terms of throughput and resource efficiency. Experimental results show that RCDP is a highly efficient solution for environments characterized by high delays and packet losses making it very suitable for intelligent transport system oriented applications since it achieves significant performance improvements when compared to traditional transport layer protocols.
UbiqBIOPARC: A Wireless and Sensor Based Context-Aware System for an Enhanced Guide Experience
Sorribes, Jose-Vicente,Cano, Juan-Carlos,Calafate, Carlos T.,Manzoni, Pietro Korea Multimedia Society 2014 The journal of multimedia information system Vol.1 No.1
This work discusses and evaluates the use of wireless and multi-sensor based technologies to develop UbiqBIOPARC, a new generation zoological park that has been created based on the zoo-immersion concept. It offers appropriate contextual information to zoo visitors, depending on their preferences and the environment in which they are positioned. It combines the flexibility of the iPhone SDK, the connectivity provided by 3G technologies, the location capabilities of GPS, and the orientation offered by a digital compass integrated in the device. In this document the overall architecture and the implementation steps followed to create this context-aware application are presented. We compare our system with respect to previous ones and demonstrate that UbiqBIOPARC is an example of how innovative context-aware applications can be built with the aid of GPS and compass features. Several real experiments have been carried out in order to evaluate performance and system behavior, and numerical results demonstrate the practicality offered by our application, while providing a quite reasonable performance in terms of delay, usability, and energy efficiency.
Towards a centralized route planning solution supporting time dependencies
Carlos t. Calafate,David Soler,Juan-Carlos Cano,Pietro Manzoni 한국산업정보학회 2014 한국산업정보학회 학술대회논문집 Vol.2014 No.1
Future route planning solutions are expected to provide significant Improvements in terms of route traversal times by accounting for both estimated and real-time traffic congestion states. Compared to current solutions, mostly based on static path segment costs, the main challenge is how to obtain reliable traffic congestion estimations for all the streets/avenues in a city for the different times of the day, for every day in a year. Modeling such a tremendous amount of data can be time-consuming and, additionally, centralized computation of optimal routes based on such time-dependencies has very high computational requirements. As a first approach to this problem, we propose a heuristic to reduce the modeling effort to a minimum while maintaing the benefits of time-dependent traffic congestion modeling. The effectiveness of this heuristic is assessed for the city of Valencia, Spain.
