This analysis was performed using process mining techniques and tools included in ProM Framework, an academic project of the Eindhoven Technical University. The paper describes the steps followed to extract the working process model, organizational network and statistical information. Based on the obtained results, an action plan is put in practice with the scope of improving the development process and the release result.","PeriodicalId":163447,"journal":{"name":"2014 IEEE 9th IEEE International Symposium on Applied Computational Intelligence and Informatics (SACI)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123596107","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 visual and vestibular perception of the driver can be modeled by measuring proper signals of the vehicle motion and the environment during the real-time driving of the simulator. The parameters of different drivers are then estimated using a linear difference autoregressive model structure and least-squares estimation techniques. The aim of the identification is to describe the different driver behaviors with the parameters of a driver model with similar structure. The identified driver models are validated by simulation using the same excitation signals as in the simulator experiment and comparing the measured and simulated output of the driver. The main novelty of the paper is the identification method in which a real-time simulator is used.","PeriodicalId":163447,"journal":{"name":"2014 IEEE 9th IEEE International Symposium on Applied Computational Intelligence and Informatics (SACI)","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134425200","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 motivated by so-called fuzzy concept lattices with hedges and represents their slight modification. In fuzzy set theory, modifiers are often defined within the framework of linguistic variables, representing adverbs, while one-sided concept lattices provides the specific fuzzy version of data analytical method based on the approach known as Formal Concept Analysis. We define concept forming operators based on separable modifiers and we show that these operators form a Galois connection between power set of objects and fuzzy subsets of attributes. An algorithm for a creation of one-sided concept lattices with separable modifiers is also presented.","PeriodicalId":163447,"journal":{"name":"2014 IEEE 9th IEEE International Symposium on Applied Computational Intelligence and Informatics (SACI)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129697953","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}

Existing tools have been targeted at controlling the blood glucose level and generating alerts against hypo/hyper-glycaemia events, individualizing risk prediction based on epidemiological knowledge, or improving patient's education and motivation. We propose analyzing contextual data from patients, i.e. using data collected through mobile devices, on a daily basis, to uncover the implications of the life style and individual behaviour towards the risk for diabetic complications.

In these kinds of monitoring systems the patient-specific evaluation is essential to obtain realistic result thereby making use of the system more secure. This requirement is fulfilled by the risk assessment framework published by the author and her colleagues. However, it is also equally important to obtain the accurate result in time to avoid the serious consequences. In order to address this problem in this paper the author presents some evaluation structure reduction techniques which reduce the computational need of the risk assessment. These models are the modifications of the conventional Mamdani-type inference system maintaining its advantageous properties while the computational complexity is reduced and the result is equivalent to the conventional system result.","PeriodicalId":163447,"journal":{"name":"2014 IEEE 9th IEEE International Symposium on Applied Computational Intelligence and Informatics (SACI)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126983913","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}

Yet, with proper care, a diabetic person can have a normal life and prevent complications. We believe technology could be a valuable helping tool, providing adequate decision support to diabetics. Our idea consists in realizing an intelligent system (DeeDee system) to assist a diabetic through the daily life, implemented on a mobile phone, a device to be carried on oneself along the day. The essence of this system is a new mechanism for glycaemia prediction. Existing mechanisms for glycaemia prediction are based on patient's continuous monitoring, i.e., the patient is placed into a controlled environment (a hospital), while our system aims to predict glycaemia and hence to help the patient through his/her everyday life. Compared to a continuous monitoring situation, in our case the amount of data obtained from the patient is much less. In order to correctly predict the value of glycaemia, our system relies on similar situation from diabetic's past. A key concept needed to ensure the functionality of the entire system is the construction and the management of diabetic's profiles. Each profile is automatically built such that it characterizes and groups similar situations from diabetic's life, i.e., how the diabetic's organism has reacted in these situations. In order to group correctly the similar situations, we need the context parameters recorded at that time moments. These parameters are continuously collected by the patient's mobile phone. This article proposes an integrated system capable to communicate with other medical equipments, having one main goal: to help a diabetic to have a better life.","PeriodicalId":163447,"journal":{"name":"2014 IEEE 9th IEEE International Symposium on Applied Computational Intelligence and Informatics (SACI)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123960231","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}
