The spreading of information can be quite fast and widespread without central control within this ad hoc network. In this position paper, we want to characterize some spatial aspects of the spreading process. We planned to analyze the radius of gyration and the bounding box of the 2 D positions of informed agents and communication events. First simulation results show a crossover in the time evolution of the system.","PeriodicalId":414016,"journal":{"name":"International Conference on Complex Information Systems","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122205935","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 chance constrained problem is proven to a convex optimization problem. The low interest rate of loan benefits borrowers. On the other hand, the high interest rate of loan doesn’t benefits lenders because such a loan is not often used. For deciding a proper interest rate of loan that benefits both borrowers and lenders, a new method is proposed. Experimental results show that the loan is used completely to improve the efficient frontier if the interest rate is decided by the proposed method.","PeriodicalId":414016,"journal":{"name":"International Conference on Complex Information Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129678445","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 uncertain version of a permutation flow-shop problem with interval execution times is considered. The worst-case regret based on the makespan is used for the evaluation of permutations of tasks. The resulting complex minmax combinatorial optimization problem is solved. The heuristic algorithm is proposed which is based on the decomposition of the problem into three sequential sub-problems and employs a paradigm of evolutionary computing. The proposed algorithm solves the sub-problems sequentially. It is compared with the fast middle point heuristic algorithm via computer simulation experiments. The results show the usefulness of this heuristic algorithm for instances up to five machines.","PeriodicalId":414016,"journal":{"name":"International Conference on Complex Information Systems","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127742579","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 context, people express their fear, panic, shock, as well as gratitude, well-wishing, and empathy as a crisis event evolves over time. Though emotional responses during crisis events have been studied both in offline and online settings, it is yet unclear which communication structures are representative for the exchange of specific types of emotions. In this paper, we report on new findings which indicate that not all negative emotions are exchanged in the same way. In particular, we used emotion-exchange motifs to compare the structure of emotion-annotated communication networks that resulted from 18 crisis events. Our findings clearly indicate that 1) exchanges of sadness on the one hand, and joy / love on the other show more structural similarity than any other pair of emotions, 2) emotion-exchange networks can be clustered into two families, each of which includes different types of emotions, 3) membership in the two families of emotion-exchange networks fluctuates over time.

A system of continuous complex event query with dynamic rule definitions and high performance is needed to process that target data. We develop a continuous complex event query system with rule-based layered architecture. A continuous processing flow is decomposed into four modules hierarchically, which are event filtering, event capture, Continuous Queries (CQ) and Complex Event Processing (CEP). Each module has its responsibility but works together for a completed continuous processing flow. This paper shows that it is possible to dynamically insert, update, delete and search rule specifications of each layered modules through the decomposition of the whole system. Many rules are registered in the system for processing input event data continuously in real time. To improve the performance of getting matching CQs for each incoming event, CQ index is developed. Finally, experimentations and performance evaluations are","PeriodicalId":414016,"journal":{"name":"International Conference on Complex Information Systems","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116988937","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}

Similarly, changes in the harmonics of Earth’s gravitational field model are an indication of environmental changes and provide a measure of the mass redistributions causing these variations. There are four independent space geodetic techniques today that monitor Earth’s geometric and dynamic parameters very accurately: Very Long Baseline Interferometry (VLBI), Satellite/Lunar Laser Ranging (SLR/LLR), Global Navigation Satellite Systems (GNSS) and Doppler Orbitography and Radiopositioning Integrated by Satellite (DORIS). These techniques have been operational for decades, collecting a very large amount of data that after appropriate processing provide, among other things, the Earth geometric and dynamic parameters used in global climate change monitoring. The same techniques are also necessary for the establishment and maintenance of the International Terrestrial Reference Frame (ITRF). To make the large amount of data more easily usable, scientists and engineers employ reduction techniques to significantly reduce the amount of raw data with minimal loss of information. It will be shown that the total amount of data available today is of the order of exabyte. Due to the complexity of data management and processing several national and international bodies have been established.","PeriodicalId":414016,"journal":{"name":"International Conference on Complex Information Systems","volume":"194 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116140170","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}
