From the navigational and marine hydro-dynamical point of view, the accurate calculation or at least reliable estimation of attainable ship speed at actual sea is essential both from economic and environmental aspects. Reliable ship speed loss estimation under real environmental conditions allows a more accurate prediction of the power increase and fuel consumption as well as gas emissions from ships. On the other hand, technological enhancements like improved hull designs as well as improvement in power and propulsion systems could potentially reduce CO2 emission up to 35%. These measures could effectively be combined with several other operational measures, such as optimal weather routing and voyage planning for ships, in order to ensure that fuel consumption and CO2 emissions from ships are minimized on every voyage. An appropriate strategy for greener shipping based on aforementioned approaches is proposed in this paper.","PeriodicalId":424325,"journal":{"name":"Proceedings ELMAR-2014","volume":"35 10","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114117973","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}

After a brief introduction into the problem of reliable real-time delivery of data using IP, major challenges to overcome are identified as packet reordering and packet loss. Both of the methods presented in this paper for improving reliability of real-time video delivery over IP networks focus on the mitigation of the effects of packet reordering and packet loss. Both methods use multiple packet transport routes to carry the signal from sender to receiver, but one method relies on use of RTP protocol and FEC error correction while the other method relies only on the use of information contained within Transport Stream packets.","PeriodicalId":424325,"journal":{"name":"Proceedings ELMAR-2014","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131635938","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}

A significant contribution to air pollution caused by the activities related to maritime traffic refers to traffic of cruise ships, which regularly consume considerable amounts of fuel in ports due to increased demand for electricity. The combustion of these fuels results in emissions containing relatively high concentration of sulfur and nitrogen oxides, as well as carbon dioxide. In the form of fine particulate matter (PM2.5) they contaminate the environment and become dangerous to the health of living beings. With the increase in the traffic of cruise ships the amount of ship emissions is also increasing and thus the contribution to air pollution is becoming highly important. This paper analyzes the impact of cruise ships on the air quality in the city of Dubrovnik, according to data from measuring station Žarkovica.","PeriodicalId":424325,"journal":{"name":"Proceedings ELMAR-2014","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117075052","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 linear time-frequency representation is achieved using the Local Polynomial Fourier Transform (LPFT), which allows revealing data local behavior. Based on the LPFT, the frequency-chirp rate domain is used to achieve sparse signal representation. Then the LPFT is combined with the L-statistics to collect only the time-frequency points belonging to the desired signal, while the points belonging to overlapping regions and disturbance are deemed inappropriate and omitted from observations. The relationship between the measurement and sparsity domain is established in order to use the compressive sensing concept and to completely recover the desired signal. The theory is proven on examples.","PeriodicalId":424325,"journal":{"name":"Proceedings ELMAR-2014","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124032939","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}
