However, a mobile host holding data items frequently accessed by other hosts needs to transmit them many times and consumes more power than other hosts. In this paper, we propose a replica allocation method for not only improving data accessibility but also balancing the power consumption among mobile hosts. In this method, each mobile host replicates data items considering their access frequencies, the numbers of their replicas, and the remaining amount of its battery. We present simulation results to evaluate the performance of our proposed method","PeriodicalId":250624,"journal":{"name":"Fourth Annual IEEE International Conference on Pervasive Computing and Communications Workshops (PERCOMW'06)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114388480","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 think that the energy efficiency and the quality of the localization services (QoLS) are equally important properties of localization systems. We refer to the QoLS as the timely supply of the location information to the applications. Energy efficiency and quality are seemingly two contradictive goals in terms of determining the rate of triggering the localization systems to perform the necessary computation and communication. In that, a lower location sampling rate contributes to a lower level of energy consumption but in the meantime compromises the timeliness of acquiring the location information. Opting for energy efficient and quality localization services, we propose a mobility-aware mechanism that adapts the sampling rate to the target mobility. Results from our simulations confirm that the adaptive sampling approach is promising and effective","PeriodicalId":250624,"journal":{"name":"Fourth Annual IEEE International Conference on Pervasive Computing and Communications Workshops (PERCOMW'06)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129146211","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}

The extraction of metadata from the multimedia resources is one of the main parts of this paper. The recorded lectures are transcripted by an out-of-the-box speech recognition software. The speech recognition software generates a time stamp for each word. These resources are divided into clusters, marked by timestamps, so that search engines are able to find the exact position of particular information inside a course. Finally, a retrieval method is presented that allows users to find \"example\", \"explanation\", \"overview\", \"repetition\", \"exercise\" for a particular word or topic-word.

Nevertheless, the thrombolytic therapy may have hazard effects on AMI patients that present any contraindication to it. As a consequence, paramedics usually hesitate about applying the thrombolytic therapy - preferring to immediately transfer patients to coronary care units (CCUs) - unless cardiologists support their decision. To cope with this scenario, we envision a ubiquitous telemedicine system for supporting cardiologists and paramedics in (i) the remote decision upon the eligibility of AMI patients to the thrombolytic therapy and (ii) the remote monitoring of patients being transferred, so-called In this paper, we present AToMS (AMI teleconsultation & monitoring), a system that makes extensive use of (possibly heterogeneous) wireless communication technology to allow its use by a paramedic at the location where the AMI patient is first assisted, thus reducing the delay between the onset of symptoms and the eventual application of proper treatment.
