Rarely is the hybrid option of using both techniques explored. Much research already exists concerning the identification and selection of custom hardware blocks from hardware/software partitioning techniques, but the question of how to best use this hardware within a user system where both coprocessors and datapath augmentations are possible remains. This paper looks to extend existing ISE algorithms which provide custom hardware as dataflow graphs (DFG) and place them appropriately within a hybrid System-on-Chip (SoC) using standard combinatorial optimization techniques. A combinatorial model is presented to address this placement issue and is applied to two well known kernel programs. We further show that such standard techniques can execute within a reasonable time frame alleviating the need for heuristics.","PeriodicalId":334381,"journal":{"name":"2011 6th IEEE International Symposium on Applied Computational Intelligence and Informatics (SACI)","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123723688","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 for this a good model of a greenhouse is needed. For a large variety of industrial or recreational greenhouses the derivation of a fully blown analytical model is not feasible and simplified models serve no practical purpose. Thus black-box modeling has to be applied. Identification (learning) of black-box models requires large amount of data from real greenhouse environments. After recording long time series of greenhouse measurements to serve its purpose the data has to be checked for validity. Measurement errors or missing values are common and must be eliminated to use the collected data efficiently as training samples for the greenhouse model. This paper discusses problems of cleaning the measurement data collected in a well instrumented greenhouse, and introduces solutions for various kinds of missing data problems.","PeriodicalId":334381,"journal":{"name":"2011 6th IEEE International Symposium on Applied Computational Intelligence and Informatics (SACI)","volume":"267 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132787494","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 latter is a key point of the diabetes “closing the loop” problem and its primary prerequisite is a valid model able to describe the blood glucose system. Among the many models appeared in the literature, the model of Magni et al [9] is widely used and represents a relatively complex nonlinear model with glucose absorption as well as subcutaneous glucose and insulin dynamics incorporated into its structure. Our aim is to hide the nonlinearity of this model by transforming the signal coming from a linear controller so that the response of the model would mimic the behavior of a linear system, desirably the one acquired through steady-state linearization; hence the validity of linear controllers could be extended. The nonlinear method known as asymptotic tracking of a linear system and presented in [13], needs the values of the state variables; hence a Kalman-filter extended for nonlinear systems is used. The capabilities of this approach are examined through simple control algorithms and realistic input scenarios.","PeriodicalId":334381,"journal":{"name":"2011 6th IEEE International Symposium on Applied Computational Intelligence and Informatics (SACI)","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133897652","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}

That is way it is necessary to embed the event processing technology into multi-agent systems decision mechanism. From the stimuli received by the agent, there are selected only the ones which can influence their behaviour and based on this information the complex event processing module gives as output complex events. These complex events result from a series of operations like grouping, aggregation, sorting, filtering, merging, splitting or duplication of events.

Huge differences exist regarding several characteristics of data, voice and video content traffics. While data traffic requires error free services, real time applications like interactive video transfer and VoIP distress of the high delay and jitter values. DiffServ becomes more and more popular Quality of Service (QoS) mechanism not only in WAN but LAN environment as well. Coloring the IP packets of different traffic streams based on QoS traffic classes generate increased diversification of the statistical characteristics detected at the measuring points of the production network. Self similarity, long range dependence and fractal characteristics of these packet flows are strongly influenced by the QoS parameters in congested network environment. Several models are proposed for the qualitative and quantitative evaluation of physical phenomenon supervened on different OSI layers at the intermediate nodes. Most of these claims relatively long traces to evaluate the scale independence and fractal characteristics. The wavelets based Multi Resolution Analysis (MRA) proposes fast pyramidal algorithm requiring ∼O(n) computation steps for determining the self similarity measure of the traces with n samples, consisting serious interest in the low delay aspect of the burst detection. In this paper several UDP and TCP traffics are considered and statistically analyzed based on MRA method. Fast detection algorithm of real time traffic burstiness is presented for QoS based packet switched WAN environment with congestion.","PeriodicalId":334381,"journal":{"name":"2011 6th IEEE International Symposium on Applied Computational Intelligence and Informatics (SACI)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125180646","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}

Along them, monitoring systems were developed in order to increase the quality of the provided services. The research areas in this field have split in two directions: monitoring systems for tracking the products from delivery source to final destination, including temporary storage information along the transportation path and monitoring systems designed to provide environment information during transportation. For some type of products (e.g. food) the quality of the product is highly dependent on the quality of the transportation conditions. This paper describes a monitoring concept based on a wireless sensors network used for environment characterization and product storage during transportation. Wireless sensor networks are highly feasible for this type of applications in terms of performance and ease of use, but in the same time they bring a set of design challenges like autonomy, information security, data throughput and resistance to harsh environmental operating conditions.","PeriodicalId":334381,"journal":{"name":"2011 6th IEEE International Symposium on Applied Computational Intelligence and Informatics (SACI)","volume":"111 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117282606","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}
