If an object is so small that little features can be used to support recognition procedure, the relationship between multi-objects could be helpful. In many cases, small objects are likely to be arranged by some regular shapes. To recognize these arrays, the paper presents a spatial topology detection algorithm. We call it as S-Prim (Spatial Prim) algorithm which is based on classic Prim algorithm, and integrates the fuzzy spatial information. The algorithm evaluates the spatial distribution regularity among neighboring nodes by back searching the path in the found tree when it is growing, and controls its growing direction according to some fuzzy rules to find out the most likely regular spatial topology. The detected tree can be considered as a spanning tree constrained by topological structures.","PeriodicalId":267532,"journal":{"name":"2012 Second International Conference on Intelligent System Design and Engineering Application","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132672749","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}

However, over 90% of schedule, the diesel engine runs at low load, bringing about problems such as inadequate torque, high fuel consumption, high heat load and etc. And directly impact operation of power and economy. The key point to improve low-load performance of marine turbocharged diesel engine is that the turbocharger can fully use exhaust energy. In this paper, variable volume exhaust pipe technology is applied as pulse turbo charging system to enhance waste gas utilization, and hence guarantee sufficient energy for turbocharger, improve low-load performance and reduce ship operating cost.","PeriodicalId":267532,"journal":{"name":"2012 Second International Conference on Intelligent System Design and Engineering Application","volume":"135 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114662973","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}

As for that, auxiliary bracing is necessary. Using FEM software, an optimization strategy has been proposed. Firstly, based on equivalent inertia moment method, the boom system can be simplified, after that a model of boom system would be set up. Secondly, with different optimization methods, the length of bracing and the position where it is pining with boom are optimized. The results derived from different methods would be compared to infer which one would be more available. This strategy will be benefit to design auxiliary bracing system.","PeriodicalId":267532,"journal":{"name":"2012 Second International Conference on Intelligent System Design and Engineering Application","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127273355","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 Cache Coherence Protocol Using Distributed Data Dependence Violation Checking in TLS 基于分布式数据依赖冲突检测的TLS缓存一致性协议

{"title":"A Cache Coherence Protocol Using Distributed Data Dependence Violation Checking in TLS","authors":"X. Lai, Cong Liu, Zhiying Wang, Quanyou Feng","doi":"10.1109/ISDEA.2012.386","DOIUrl":"https://doi.org/10.1109/ISDEA.2012.386","url":null,"abstract":"Current hardware implementations of TLS (thread-level speculation) in both Hydra and Renau's SESC simulator use a global component to check data dependence violations, e.g. L2 Cache or hardware list. Frequent memory accesses cause global component bottlenecks. Implementation and verification of the global component dramatically slows the processor's frequency. In this paper, we propose a cache coherence protocol using a distributed data dependence violation checking mechanism for TLS. The proposed protocol extends the current MESI cache coherence protocol by including several methods to exceed the present limits of centralized violation checking methods. In order not to broadcast every exposed write to the snooping bus, the protocol adds an invalidation vector to each private L1 cache to record threads that violate RAW data dependence. It also adds a versioning priority register that compares data versions. Added to each private L1 cache block is a snooping bit which indicates whether the thread possesses a bus snooping right for the block. The L1 Cache gets a bus snooping right when setting snooping bit. The L1 Cache catches exposed read miss whose address matching cache block address field. If a read miss from a remote core with a lower versioning priority, the L1 Cache updates the invalidation vector according to the core ID on the bus. If TLS runtime is going to commit or invalidate a thread, then L1 Cache invalidates threads whose bits have been set in the invalidation vector and changes any cache blocks to a corresponding non-speculative state. In order to implement the proposed protocol, we modified the SESC simulator, which is an open-source cycle-accurate simulator, to confirm its correctness and analyze its performance.","PeriodicalId":267532,"journal":{"name":"2012 Second International Conference on Intelligent System Design and Engineering Application","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124947330","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}
