The proposed prototype, SmartATRS, is an example of pervasive computing that considerably improves the usability of ATRS. Two contributions have been made to ATRS: an improved System Architecture incorporating a relay board with an embedded web server that interfaces with the smartphone and ATRS, and an evaluation of the usability of SmartATRS using the System Usability Scale (SUS) and NASA Task Load Index (NASA TLX). The contributions address weaknesses in the usability of ATRS where small wireless keyfobs are used to control the lift, tailgate and seat. The proposed SmartATRS contains large informative buttons, increased safety features, a choice of interaction methods and easy configuration. This research is the first stage towards a \"SmartPowerchair\", where pervasive computing technologies would be integrated into the powerchair to help further improve the lifestyle of disabled users.","PeriodicalId":345016,"journal":{"name":"2015 International Conference on Pervasive and Embedded Computing and Communication Systems (PECCS)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124910244","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Meanwhile, the capacity to monitor and register not only data about people's habits and locations but also more complex data such as intensity and strength of movements has created an opportunity to their contribution to the general wealth and sustainability of environments. Ambient Intelligence and Intelligent Decision Making processes can benefit from the knowledge gathered by these devices to improve decisions on everyday tasks such as planning navigation routes by car, bicycle or other means of transportation and avoiding route perils. Current applications in this area demonstrate the usefulness of real time system that inform the user of conditions in the surrounding area. Nevertheless, the approach in this work aims to describe models and approaches to automatically identify current states of traffic inside cities and relate such information with knowledge obtained from historical data recovered by ubiquitous and pervasive devices. Such objective is delivered by analysing real time contributions from those devices and identifying hazardous situations and problematic sites under defined criteria that has significant influence towards user well-being, economic and environmental aspects, as defined is the sustainability definition.","PeriodicalId":345016,"journal":{"name":"2015 International Conference on Pervasive and Embedded Computing and Communication Systems (PECCS)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123705154","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We also present the results from the ISO 9241-9 assessment of comfort questionnaire, and our observations from the participant's postures when using the Leap Motion device.

Java Card is a reduced set of the Java standard designed for these systems. In a context of scarce resources such as smart cards, ROM size plays a very important role and dictionary compression techniques help in reducing program sizes as much as possible. At the same time, to overcome the intrinsic slow execution performance of a system based on interpretation it is possible to enhance the interpreter speed by means of specific hardware support. In this paper we apply the dictionary compression technique to a Java interpreter built on an application specific processor. Moreover, we move part of the decompression functionalities in hardware with the aim of speeding up the execution of a compressed application. We obtain a new interpreter that executes compressed code faster than a classic interpreter that executes non-compressed code.","PeriodicalId":345016,"journal":{"name":"2015 International Conference on Pervasive and Embedded Computing and Communication Systems (PECCS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125740678","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In islanded mode, only local generation resources are usable. In this mode, the availability of resources is very influenced by meteorological factors. In order to achieve a high availability of energy, microgrid has to satisfy high requirements on intelligent power management. The main objective of this study is to develop a control based on the forecast of production and the priority of loads to ensure high availability of electrical power for critical loads. A mathematical model for the proposed strategy is developed. The simulation of this model on Matlab Simulink for different cases of microgrid topology (sources and loads) shows clearly a high improvement of degree of availability of electrical power supply distribution in microgrid.","PeriodicalId":345016,"journal":{"name":"2015 International Conference on Pervasive and Embedded Computing and Communication Systems (PECCS)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124755217","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This one is qualified as real-time since jobs have to be executed before deadlines. In addition, it is an energy harvesting system since its supply energy is drawn from the environment. We assume that the preemptable jobs receive dynamic priorities according to the Earliest Deadline First (EDF) rule. We propose to extend the dynamic power management scheme called EDeg that must be adapted to a processor with DVFS capabilities. We show how to adjust dynamically the frequency in order to gain quality of service measured in terms of deadline miss rate.","PeriodicalId":345016,"journal":{"name":"2015 International Conference on Pervasive and Embedded Computing and Communication Systems (PECCS)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134403334","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nowadays, application contents are accessible on a wide variety of devices such as laptops, tablets and smartphones but the heterogeneity of such devices does not help programmers to elaborate ambient interactive applications adapted to each device. Indeed, users do not interact in the same way on a tablet, a laptop or a smartphone. Furthermore the design of cooperative HCI (Human Computer Interface) remains a very complex task especially in an ambient and heterogeneous environment. In this paper, we propose a multimodal mobile interactor model, called Txupito, and a set of composition operators as a way to achieve interactions with hardware in a distributed and cooperative way.","PeriodicalId":345016,"journal":{"name":"2015 International Conference on Pervasive and Embedded Computing and Communication Systems (PECCS)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114900793","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
