This paper has proposed a new crude oil electrostatic dehydration controller based on ARM (Advanced RSIC Machine) technology. The crude oil electric dehydration controller using combined AC/DC electrician technology. Through the three-phase and 480 v AC input, it overcomes the three-phase load unbalanced problem caused by the normal single-phase AC input of the traditional dehydration controller. Use the IGBT (Isolated Gate Bipolar Transistors) technology to produce a variable amplitude and variable frequency voltage supply for the primary of the transformer. The dehydrated tube electrode produces the high-pressure variable AC/DC field. The water drop accumulation and precipitation are caused mainly by the effort of electric field in the process of dehydration, and then it realizes highly-efficient crude oil dehydration.","PeriodicalId":231129,"journal":{"name":"2008 Fifth IEEE International Symposium on Embedded Computing","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128863190","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}

In this paper, we explore a new viewpoint that the embedded component systems can be studied as a large amount of components connected by the relationships. Here we name it the Embedded Component Network (ECN). Then we take the eCos for example and analyze basic statistics parameters. Results confirm that the eCos network exhibits typical characteristics of complex network. Then we introduce three classical node ranking algorithms, which have some shortcomings for the real eCos system. So we propose a new ranking algorithm, which provides a general framework for the classic ranking and reveals more position differences of eCos network topology.

It is comprised of one CPU and two physically isolated system buses, secure and non-secure. Only non-secure bus has Internet interfaces. Devices, storing private data, can only be accessed through secure bus. Internet related applications, only running on the non-secure bus, have no opportunity to access resources on the secure bus.

Since it is hard to obtain a stable, fast and accurate simulator in time, it poses a significant challenge especially for multi-core application specific instruction-set processors (ASIP). Presently Architecture Description Languages (ADL) is widely used to aid the design of ASIP, benefiting from automatic generation of the software tool chain. This paper identifies and describes a concept of multi-processing simulator and its implementation Lsimpp. The concept combines the ADL-based automation, the timing accurate System-C module extensions and the flexible C++ module library into a sound framework for a multi-processing simulator. The resulting Lsimpp is an extensible simulator which includes a state-of-the-art ASIP multi-core processor model, standard buses, arbiter and memories. In processor models, all the pipeline resources and operations are described in ADL. Based on the automatically generated core models, extensions have been applied to include the standard OCP TL 2 bus. A verification concept is developed to embed the single core test cases for regression tests of the simulator. Empirical experiment results on sample applications demonstrated that the simulator runs correctly with great accuracy and satisfactory performance.","PeriodicalId":231129,"journal":{"name":"2008 Fifth IEEE International Symposium on Embedded Computing","volume":"207 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131542361","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}

Fixed priority real time scheduling algorithms have low runtime complexity and their behaviour can be categorized a prior but they do not support dynamic systems very well. A transient overload in dynamic priority scheduling algorithms may cause a critical task to fail but they are capable of supporting dynamic systems. Hybrid scheduling algorithm's behaviour can be categorized a prior and they support dynamic systems as well but they may unnecessarily cause non critical tasks to miss their deadlines even when all critical tasks are schedulable.

In these networks, there are no end to end connections from sensor nodes to sink nodes due to low node density and node mobility. Therefore, conventional routing protocols in WSN are not practical for ICMSN since packets will be dropped when no complete route to the sink is available. In this paper, we propose an efficient routing protocol for ICMSN, which is composed of buffer management and message forwarding. Buffer management consists of two related components: queuing mechanism and purging mechanism. The former determines priority of messages to transmit or discard based on the importance factor, which indicates the QoS requirement of the messages. The latter utilizes a death vector generated by the sink to purge useless messages that have been delivered from the network. Message forwarding makes decision on which sensors are qualified for next hop based on node delivery probability, which synthesizes the meeting predictability to the sink, current buffer state and residual energy and increases the likelihood that the sensor can deliver the message to the sink. Our experimental results show that the proposed routing protocol not only supports the QoS requirement of different content but also achieves the good performance tradeoff between delivery ratio, delay and resource consumption.","PeriodicalId":231129,"journal":{"name":"2008 Fifth IEEE International Symposium on Embedded Computing","volume":"144 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116606369","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 can also produce many kinds of special acoustics. However, artificial reverberator is a very complex system related with many important items especially its time-delay and feedback. And it is hard for designers to find the parameter of these items accurately. Simulink is perfect tool to design the artificial reverberator and set the optimal parameter through simulation, which can result in better acoustics.
