The radioactivity information is obtained from the measured spectrum, using an algorithm for photopeak determination based on wavelet denoising methods. This algorithm improves significantly the analysis capability of a short-term spectrum with poor statistical information. The measurement data are collected by the underwater part of the system, which has built-in photomultiplier tube, preamplifier and power supply, together with the electronics for data acquisition, storage and transmission. The system can perform in-situ measurements of natural or anthropogenic radionuclides in water and can be installed on any oceanographic buoy and remotely operated or autonomous underwater vehicles. In case of an ROV/AUV installation, the system operates in a continuous monitoring and data storage mode for preliminary studies at specific aquatic areas, while use in a buoy installation is currently under development.","PeriodicalId":247264,"journal":{"name":"2008 1st International Conference on Information Technology","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114430478","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}

It includes screening experiments to quantify the parameters and interactions among parameters influential to throughput. Profile-driven regression is applied to obtain a model of the non-linear behaviour of throughput. The intermediate models obtained in this modelling effort are used to adapt the parameters as the network conditions change, in order to maximize throughput. The improvements in throughput range from 10-26 times the use of the default parameter settings. The predictive accuracy of the model is monitored and used to update the model dynamically. The results indicate the framework may be useful for the optimization of dynamic systems of high dimension.","PeriodicalId":247264,"journal":{"name":"2008 1st International Conference on Information Technology","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127115541","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 extension enables to place objects in an appropriate context in a virtual museum. Therefore it is possible to restore the true appearance of antique interiors and other spaces. On the basis of the information sorted in the system new facts concerning the objects can be discovered.

There are still some unsolved problems and new options yet to be defined. One example of such case is Fully Qualified Domain Name (FQDN) option, which final version has been published in late 2007. It describes DHCPv6 client and server behavior, but some important aspects remain unaddressed. Authors developed and released working open source implementation over a year before FQDN standard reached mature phase. This paper discuses those issues and recommends possible solutions. Another important development area in the DHCPv6 protocol is a lack of well defined authentication and authorization. Experimental AAA implementation has been developed and reached validation phase. Quick overview of the Dibbler project - a working, multi-platform, open-source DHCPv6 implementation - is also provided, its strengths, used solutions and validation methods used to prove its correctness are discussed.
