We begin with providing an introduction to the different kinds of uncertainties and associated tools that address them. A general description about the principle of modelling in stochastic environments is then represented. Two different expressions on probabilistic fuzzy sets are subsequently discussed. Moreover three distinct probabilistic fuzzy approaches facing stochastic problems are described and the ad-vantages and disadvantages related to each approach are also illustrated. Several simulations and comparative analysis are also provided to clarify the mentioned concepts.","PeriodicalId":239692,"journal":{"name":"2015 4th Iranian Joint Congress on Fuzzy and Intelligent Systems (CFIS)","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114719056","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 is implemented to level control of a real laboratories plant using real time toolbox in Simulink software and data acquisition card, considering saturation issue, and responded properly in the existence of exogenous noises and disturbances. Main idea is PID gain scheduling through fuzzy algorithm, which provides us with an adaptive control system. This plant is a single input-single output system with constant liquid in-flow, so an operating point is defined here by the in-flow rate. Any constant PID controller gains, calculated through Ziegler-Nichols, Internal Mode Control and other methods for using in a conventional PID controller with this plant, would be a function of liquid in-flow, as a parameter of plant. In fuzzy approach, however, these gains can adaptively change to not only provide the de-sired steady state response but also to reach that state very fast. Experimental results for proposed controller are reported to show the effectiveness of proposed method.","PeriodicalId":239692,"journal":{"name":"2015 4th Iranian Joint Congress on Fuzzy and Intelligent Systems (CFIS)","volume":"18 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120849579","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 consider the least square and least absolute deviation familiar methods to compare the mention models.

Nowadays, we are encountering various cloud service providers. One of important aspects in cloud computing is service level agreement which is a contract involving service agreement between client and service computer. According to this contract, violation in commitments mentioned in agreement by service provider will be punished; therefore, service providers should have solutions to reduce these conflictions in service level and costs. Regarding importance of this topic, this article deals with approaches conducted in service level agreement and its comparison regarding improved parameters, simulation or implementation environment, workload and application.","PeriodicalId":239692,"journal":{"name":"2015 4th Iranian Joint Congress on Fuzzy and Intelligent Systems (CFIS)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123461435","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 novel model, all data corresponding to the demand of customers and fortification and interdiction resources are imprecise and vague and to consider the degree of certainty of the solution. Fuzzy model of RIMF also is given as a bi-level programming with two decision maker, i.e., fortifier and interdictor. For solving the problem, the fuzzy RIMF is reformulated as a single level problem by using the Karush-Kuhn-Tucker (KKT) conditions, which is amenable to an exact approach. The single level model can be solved to optimality using CPLEX 12.5.1. Finally, a random instance is generated for illustration.

To reduce drug side effects and risks of open surgery, drug encapsulated nanoparticles (DENP) can be helpful. Architecture, computing power and functionality of these particles are designed so simple such that they can penetrate to the inner walls of the arteries and preventing the growth of atherosclerosis plaque. Very limited capabilities and local computations in the high uncertain human body, are major challenges in this area. This article proposes a method for swarm learning of nanoparticles to estimate the drug release function dynamically based on the environmental conditions. Our nanoparticles as interval agents set their outputs according to their memory and feedback from the environment. Results of the proposed method shown in terms of the LDL reduction time, ability to detect healthy tissues and controlling disturbances.","PeriodicalId":239692,"journal":{"name":"2015 4th Iranian Joint Congress on Fuzzy and Intelligent Systems (CFIS)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132201061","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}

Considering the fast growing rate of GWA studies, automatic extraction of SNP-Traits associations from text is a highly demanding task. In this research, first an SNP-Trait association corpus is produced and then a non-supervised relation extraction method grounded on linguistic-based negation detection method is proposed. The experiments show that negation cues and scope can be employed as a superior relation extraction method due to uniform polarity of the sentences, small number of neutral examples and concessive clauses in the corpus. The proposed method is a non-supervised relation extraction method which works at the sentence-level with no need to label training data. Moreover, the experiments indicate that the proposed method has a superior performance over the studied sequence kernel method.","PeriodicalId":239692,"journal":{"name":"2015 4th Iranian Joint Congress on Fuzzy and Intelligent Systems (CFIS)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128397189","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}
