The vision orientation system as an auxiliary navigation method can realize the function of high precision positioning within a large range. This paper introduces a matching constraint and layer-by-layer search structure which is suitable for GPS vision navigation system, and puts forward a feature aided multi-stage matching algorithm. The algorithm firstly makes the match of the more obvious characteristics points, then the matched points information are used to determine the subsequent points general disparity range through the geometric constraints, thus improving the matching speed and accuracy. Using different types of outdoor natural topographic map matching experiments were conducted. Experimental results show that the multi-stage matching algorithm introduced in this paper is better than the basic area matching algorithm in matching accuracy and speed.","PeriodicalId":21691,"journal":{"name":"Science Technology and Engineering","volume":"24 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2014-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88552780","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 chapter compares the main technologies for biomass combustion – spreader stoker, mass burn and biomass bubbling fluidised bed (BFB)/circulating fluidised bed (CFB) – and discusses specific issues to be addressed in the design of biomass-fired steam boiler plants. Examples of recent biomass-to-energy plants are given in order to illustrate how project-specific factors influenced the design. A section is dedicated to non-wood biomass fuels and how their characteristics affect plant design. Conversion of existing coal-fired boilers to biomass firing is also discussed. The final part of the chapter deals with operational issues of biomass-fired plants.","PeriodicalId":21691,"journal":{"name":"Science Technology and Engineering","volume":"8 1","pages":"225-277"},"PeriodicalIF":0.0,"publicationDate":"2013-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89786768","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}

Often, the main goal is the provision of energy in the form of heat or power (or cooling) by burning the combustible gases. Another goal of biomass gasification is the generation of synthesis gases for further catalytic synthesis into base chemicals or storable energy carriers such as liquid fuels (methanol, mixed alcohols, Fischer–Tropsch liquids and dimethyl ether) or gaseous fuels such as substitute natural gas (SNG) or hydrogen. This chapter describes the fundamentals of gasification, technological developments and future trends for different sizes of plants and gives an overview of the process chains incorporating biomass gasification.","PeriodicalId":21691,"journal":{"name":"Science Technology and Engineering","volume":"61 1","pages":"106-129"},"PeriodicalIF":0.0,"publicationDate":"2013-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73356184","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}
