Many solutions have been proposed to tackle this problem, but the museum constraints prevent an easy application in several cases, especially if the monitoring has to be performed in museums where an environmental control system has been already installed. This paper describes a simple though powerful solution, which complies with most of the common constraints and which is based on small sensors implementing a BT-LE wireless protocol coupled with a receiving architecture. The sensing nodes have dimensions of few centimeters, do not require cabling and power supply, and can work unattended for several years. Data are collected by a receiving architecture, which can work either on-line, with immediate data delivery, or off-line when an Internet connection is not available. Users can browse the measurements by using their smart-phones from any place and can download the data on their personal computer. In addition they can browse locally the data also in the absence of any data connection, such as in the case of remote and or recessed sites. The proposed solution has been deployed in three museums, also in the basements, and in an ancient building proving its flexibility and capability to be adapted to the different conditions.","PeriodicalId":201479,"journal":{"name":"2017 IEEE International Workshop on Measurement and Networking (M&N)","volume":"89 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129134969","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 includes radio interferometry. However, literature researches show that many distributed protocols cannot satisfy sub-ns time synchronization accuracy due to asymmetric delay errors, accumulated jitters and because of the strategy used to compute and adjust offsets. This paper proposes a global time synchronization algorithm in distributed networks. The algorithm allows us to compute and adjust offsets delays between master and each slaves in star topology and minimize asymmetric delays with sub-ns accuracy better than 10 ps and achieved global time synchronization. The theory of the algorithm used is presented and analyzed to prove that it achieves global time synchronization. Simulation results are given to show the performance and limitations of the proposed algorithm.","PeriodicalId":201479,"journal":{"name":"2017 IEEE International Workshop on Measurement and Networking (M&N)","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132176194","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 commitment to user satisfaction can be summarized by different concepts, content providers emphasizing quality of experience (QoE), whereas network providers are more focused on quality of service (QoS). Measuring QoS parameters, and understanding the relationship between the two, is essential to enable network tuning for enhanced QoE. Analysis of actual streaming dynamics and detection of impairments require the ability to discriminate between audio and video packet flows. For the purpose we present a cross-layer analysis based on the study of packet flow features obtained by implementing a Support Vector Machine. This paper presents results of a study supported by the use of nTh HighSee, a non-intrusive QoS monitoring tool, where approaches to video/audio detection have been investigated and tested.","PeriodicalId":201479,"journal":{"name":"2017 IEEE International Workshop on Measurement and Networking (M&N)","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132179812","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}

IEEE Std. 802.15.6 defines the communication protocol for WBSN applications in terms of physical and medium access layers. The high generality and flexibility of standard requirements poses the question of how WBSN parameters, i.e. sampling frequency, node priority, superframe duration, have to be carefully set to guarantee a given accuracy level for the extraction and estimation of the biomedical information of interest. In this context, the present paper focuses on the most suitable design of network configuration by considering how the occurrence of missing packets affects the resulting quality of service. Throughout numerical simulations in Matlab, we reproduce a plausible WBSN scenario for monitoring the cardiac activity during physical exercise. The effect of missing packets on the recovered electrocardiographic (ECG) time-series at receiver side has been finally investigated, in terms of root-mean-square error and accuracy of the estimated heart rate, thus providing some criteria for choosing the most suitable network configuration.","PeriodicalId":201479,"journal":{"name":"2017 IEEE International Workshop on Measurement and Networking (M&N)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115802248","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}

What influences the choices we make? Answering this question can be a very daunting task. However, it can help us to identify the main key elements that influence the behaviour of people. Arguably the weather conditions have a major impact in our daily decisions and events, with the more extreme weather having a stronger influence our lives. How can we tie Human behaviour to environmental conditions? Can we determine the human behaviour during a catastrophic environmental event? To answer these questions, we can query various information sources including social networks. These represent a good starting point with respect to the analysis of a human behaviour aspect.

The goal is to increase the performance of the recently deployed transmission system in terms of availability and reliability, given the high seismic risk and hazard associated with the experiment.

Such a NF/FF transformation, relying on the nonredundant sampling representations of electromagnetic fields, requires practically the same number of NF data both when the antenna under test (AUT) is onset and offset mounted, since such a number depends only on the surface modelling the AUT. It is developed by properly applying the unified theory of spiral scannings for non-volumetric antennas, when the AUT is considered as contained in a flexible surface formed by two circular bowls with the same aperture and eventually different bending radii. Some numerical results assessing the accuracy and the robustness of the proposed technique are shown.","PeriodicalId":201479,"journal":{"name":"2017 IEEE International Workshop on Measurement and Networking (M&N)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133730129","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}
