One of the major issues in modelling radio waves propagation inside railway tunnels is the accurate representation of tunnels' geometry in the format of digital raster maps, which are used to model indoor terrain features, by the Geographical Information System (GIS) embedded in the radio planning software ICS Telecom ® (produced by ATDI SA), used throughout the radio design procedure presented herein. The production of the tunnel digital raster maps relies on a very simple and also original engineering method, which converts the large scale situation plans of the railway tunnels, readily available at the railway infrastructure operators in electronic format (Autocad), to the desired raster map format, with a 0.1 meters resolution. The last section of the paper describes in detail the selection and configuration of the indoor radio propagation models and presents the results of the radio design procedure. The whole approach of the paper is highly practical, being presented as a radio design case study, for the “Dealul Negru” railway tunnel, situated on the Braşov - Sibiu railway corridor.","PeriodicalId":273985,"journal":{"name":"2012 IEEE 18th International Symposium for Design and Technology in Electronic Packaging (SIITME)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115671779","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}

Through developing of a crosstalk avoidance code (CAC) is possible to create a forbidden transition channel (FTC) that prevents transitions responsible for generating crosstalk, [2]. Rules used in developing a CAC can be very complex, and because of that in some papers is explained only the coding algorithm without given a description of the coder/decoder (CODEC). Some of the CAC presented in literature can have only a theoretical point of view, the physical implementation raising problems regarding the real time execution requirements of such a system [3]. In section IV of the paper is explained how the proposed CAC in [4] can be extended to code a larger bus structure and implement the CODEC. In order to compare the proposed CAC performances, were implemented other two algorithms that try to mitigate crosstalk effects ([1] and [2]). In the paper are presented not only SPICE results, but also measured results obtained on a physical off-chip parallel data bus test setup.","PeriodicalId":273985,"journal":{"name":"2012 IEEE 18th International Symposium for Design and Technology in Electronic Packaging (SIITME)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126494038","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}

During Vapour Phase Soldering Galden fluid is heated, forming a layer of vapour inside the sealed processing zone of a VPS station. The controlling of transferred heat is done through condensation, and the amount of condensation depends on the temperature of the board and the amount of available vapour. The basic method of VPS implies soldering should be carried out under steady state conditions with saturated vapour. Therefore, identification of the level of the saturated vapour layer is essential. Yet, this is commonly accomplished only by temperature measurements inside the processing zone [2]. This paper presents how pressure parameters of the processing zone of an experimental VPS system were measured with novel methods. The results indicate that from the aspect of soldering, the saturated vapour indication is more precise and immediate than temperature measurements with thermocouples.","PeriodicalId":273985,"journal":{"name":"2012 IEEE 18th International Symposium for Design and Technology in Electronic Packaging (SIITME)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132216982","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}

Present DC-DC converters are designed for a single power source resulting in low output power if the harvested heat energy source has low temperature. This drawback can be eliminated with Buck-Boost DC-DC converters able to adjust the output current accordingly to the variation of the available heat source temperature. In order to increase the efficiency, the proposed Ćuk converter employs two N-Mos switches where the second replaces the diode from the original topology. An isolation transformer is used to revert the output polarity and high resolution nanosecond adjustable timing will be used to prevent the cross conduction of the switches. The converter employs an indirect current control loop by measuring only the output voltage of the thermoelectrical generators, eliminating the need for a current sensor. An a priori built look-up table stores the voltage - internal resistance correspondence of the TEG and is used to compute the actual current the converter is sourcing to the battery pack.","PeriodicalId":273985,"journal":{"name":"2012 IEEE 18th International Symposium for Design and Technology in Electronic Packaging (SIITME)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129909833","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}
