In order to achieve this goal, the study invested in the existing studies and selected ARIMA and Fb-Prophet time series models as the methods to predict confirmed and death cases in the following year. In a comparison of both models using values of their evaluation metrics, root-mean-square error, mean absolute error and mean absolute percentage error show that ARIMA performs better than Fb-Prophet. The study also discusses the reasons for the dramatic spike in mortality and the large drop in deaths shown in the results, contributing to the literature on health analytics and COVID-19 by validating the results of related studies.

Logical models are here presented as theories for implementation design on iDevice, with respect to the algebraic structure caused by state transitions. As a simpler design of complex AI, the environmental constraint is captured as a state, where the function applications are available at each state with the transition to the next states. For communication to the state, and function applications at the state, multi-modal logic model may be of use, where the formula or the condition monitors the state. Then interaction availability is significant, expressed in some algebra on the basis of the meaning definitions for formulas (conditions). By the state transition system, URL searching operations are now formally considered as in algebraic structure. The application of predicates to the states is regarded as applications of functions (transforming conditions) such that its algebraic structure may be given.","PeriodicalId":414016,"journal":{"name":"International Conference on Complex Information Systems","volume":"32 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":"122184919","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}

At present, disaster research focuses on bottom-up approaches such as civilian inclusion in disaster response. With the advent of smartphones, citizen-based emergency communication has become possible. Present ad hoc communication technologies typically form a fully connected mesh network, which connects all phones that are within each other's transmission range. This facilitates low-latency direct communication between citizens, but it quickly drains the battery of phones. Alternative ad hoc communication networks form an adaptive energy-efficient network topology, that is most draining to batteries of phones that have a higher charge, while low-energy phones are spared from relaying messages, thereby preserving battery and thus maintaining their connection with the rescue communication network. Both of these approaches have their own advantages. Which one is best for communication needs depends on the context. This position paper discusses the possibility of a decision model as an approach to automatically switch between the two alternative ad hoc communication networks. This ensures that citizens in disasters can make use of the optimal communication system at all times.","PeriodicalId":414016,"journal":{"name":"International Conference on Complex Information Systems","volume":"38 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":"124499221","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}

We construct a weighted network with nodes as PACS codes and there is a link between two PACS codes if there is an article assigned to both these codes. The weight of a link represents the number of articles in which both PACS codes appears. We study the time evolution of PACS network at various hierarchy levels of PACS codes. We observe that sub-fields Physics of elementary particles and fields, Nuclear Physics and Condensed matter physics have stronger connections inside the field compared to connections to other sub-fields.

Despite DAGs are very expressive to reflect dependencies relationships, current approaches are not aware of the storage physiognomy in terms of performance and capacity. Provide information about temporal storage allocation on data intensive applications helps to avoid performance issues. Nevertheless, we need to evaluate several combinations of data file locations and application scheduling. Simulation is one of the most popular evaluation methods in scientific workflow execution to develop new storage-aware scheduling techniques or improve existing ones, to test scalability and repetitiveness. This paper presents a multiworkflow store-aware scheduler policy as an extension of WorkflowSim, enabling its combination with other WorkflowSim scheduling policies and the possibility of evaluating a wide range of storage and file allocation possibilities. This paper also presents a proof of concept of a real world implementation of a storage-aware scheduler to validate the accuracy of the WorkflowSim extension and the scalability of our scheduler technique. The evaluation on several environments shows promising results up to 69% of makespan improvement on simulated large scale clusters with an error of the WorflowSim extension between 0,9% and 3% comparing with the real infrastructure implementation.","PeriodicalId":414016,"journal":{"name":"International Conference on Complex Information Systems","volume":"124 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":"132947314","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}

Despite the potential for experiencing discrimination or stigmatization, research suggests that revealing a concealable stigmatized identity (CSI), or any identity that can be hidden but when revealed has the potential for social devaluation, often leads to positive psychological and interpersonal outcomes. However, this typically only happens when a disclosure confidant provides support in response to disclosure. Therefore, this work aims to uncover how someone’s antecedent goals (either approach or avoidance oriented) can impact the disclosure event using an embodied perspective whereby goal orientation has the propensity to affect unconscious behaviors such as postural sway. Healthy adults typically exhibit complex, fractal sway behaviors; therefore, any loss of complexity could be associated with maladaptive disclosure motivations. Finally, we suggest a future plan of research aimed at capturing the disclosure confidant’s perception of the disclosure event and if they are more likely to exhibit complexity matching in their postural sway behaviors as a function of disclosure motivation.","PeriodicalId":414016,"journal":{"name":"International Conference on Complex Information Systems","volume":"26 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":"133157700","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}
