Fault models and tools targeting the extraction of these defects focused only on the bridging faults in order to generate test patterns or to use this information for a precise fault diagnosis. However, for open defects there is no available commercial tool that performs the extraction of this defect. In this paper, we present a novel algorithm to extract the location of potential open defects caused by defective vias. This information is used to generate a subnet list containing the name of disconnected segments by each defective via. Experiments on real industrial designs show the algorithm's performance. The method proposed in this paper is supported by a design flow implementing existing commercial CAD tools.","PeriodicalId":126072,"journal":{"name":"2009 3rd International Conference on Signals, Circuits and Systems (SCS)","volume":"225 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114744591","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}

An expert system JESS (Java Expert System Shell) is integrated with the ontology. Knowledge inference is then possible to solve maintenance cases by given adequate diagnoses to given symptoms.

To better understand their electrical properties a combined study is presented considering both their macroscopic and mesoscopic electrical behavior. Molecular beam deposition is used to deposit thin films of ZrO2 as well as (ZrO2) x(Al2O3)1−x. Three different ZrO2 deposition methods are compared and evaluated by capacitance voltage (CV) and current voltage (IV) measurements. These deliver valuable information for benchmarking. To further understand the leakage current mechanism in nanometer thin zirconate based films conductive atomic force microscopy is performed. IV curves are taken with high spatial resolution enabling a detailed comparison between the leakage paths at crystallites and in the amorphous matrix. Through this method the evolution of the leakage path formation can be traced.","PeriodicalId":126072,"journal":{"name":"2009 3rd International Conference on Signals, Circuits and Systems (SCS)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129230244","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}

For the fixed or portable applications, the channel can be considered as a static. In this paper, we propose to use channel prediction in order to improve the performances of resource allocation algorithms, in term of outage probability and average throughput. Moreover, for a dynamic OFDMA system, when different traffics are offered at each time slot, a good scheduling of the available resources among the users is necessarily. We propose an algorithm of resource allocation based on both the prediction of the channel and the traffic in order to overcome the buffer overflow. For a Constant Bit Rate (CBR), we show that the channel prediction yields a significant average throughput.","PeriodicalId":126072,"journal":{"name":"2009 3rd International Conference on Signals, Circuits and Systems (SCS)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125469279","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 proposed method combines the adapted SPIHT (Set Partitioning In Hierarchical Trees) method with VKTP (Vector K-Tree Partitioning) coder. The SPIHT method is based on the use of wavelet transform which is very well suited to locate the energy of the signal in fewer coefficients. Using the VKTP algorithm, to encode the generated bit stream of SPIHT algorithm, we achieve high compression performances. The tests of this lossy compression/ decompression technique are performed on many ECG records from Arrhythmia Database. The obtained results illustrate the capabilities of the proposed approach to improve the compression ratio while maintaining a good signal quality.","PeriodicalId":126072,"journal":{"name":"2009 3rd International Conference on Signals, Circuits and Systems (SCS)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127619582","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 is well-known that due to the nature of multi-hop wireless Ad hoc network applications, TCP throughput instability can have a devastating impact on the QoS requirements and is regarded as one of the main TCP problems. In this paper, we first illustrate the TCP throughput instability simulation results for a chain-topology network that uses the IEEE 802.11 medium access control protocol and ad hoc routing protocol. We then discuss why the performance of TCP is poor in this scenario. A simple solution is proposed that enables the DSR routing protocol to reduce its trigger of unnecessary route error process due to MAC collisions which interrupts and affects the TCP link operation, and forces the TCP congestion window to enter the slow start phase leading to deteriorated and unstable TCP throughput. Our proposed solution enforces the TCP sender to recover packet losses of data by fast retransmit / fast recovery TCP mechanism without resorting to the coarse grained Retransmission Time Out (RTO), which is often detrimental to throughput. It is shown that our modification in DSR has caused significant improvement in TCP throughput stability for the chain, grid, and random mobile topologies compared to TCPs over standard DSR.","PeriodicalId":126072,"journal":{"name":"2009 3rd International Conference on Signals, Circuits and Systems (SCS)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130056957","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}
