This evolution posed a problem for operators to support Voice service in 4G LTE without depending on their 2G and 3G networks. 3GPP and GSMA (GSM Association) offered a wonderful solution for that to support voice over IP (VoIP), and that by installing an IMS (IP Multimedia Subsystem) infrastructure that offer voice service and connect LTE Network to it, we call that \"VoLTE\". Therefore, VoLTE is clearly the future of voice communications since it is over IP and it is compatible with NGN (Next Generation Network) in the fixed network part, also it can ensure a very good QoS (Quality of Service) because IP packet was designed to support high data throughput. This research paper analyzes the influence of link utilization and network congestion on end-to-end basis VoLTE performance. Different scenarios are simulated using LTE-Sim simulator tool in a good way.

Furthermore, the article provides criteria for evaluating the method. The main argument of the study is that the ECM is ideal for reconstructing a known theory to a new context; particularly, when the objective is to theorize how different information systems respond to that context. The method promotes a \"systemic significance\" based on the topology of those systems rather than a statistical significance. The study provides the background of the ECM and argues its differences from alternative interpretative research methods in IS. After that, the paper elaborates an illustration of how to support the theoretical and practical relevance of the context, the selection of the theory, the commonalities and differences among information systems, and the extension of the theory, in research guided by the ECM.","PeriodicalId":414028,"journal":{"name":"Proceedings of the 9th International Conference on Information Systems and Technologies","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125041332","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}

Active disputes are being held on the definition of the term \"corruption\", the impact of corruption on economic growth, the effectiveness of corruption for the economy as a whole, as a regulator it is worth fighting against corruption. In addition, the literature on corruption lacks the organization and generalizations of the main findings. The purpose of this scientific work is to review the economic literature and systematize the conclusions in the discipline. The current work begins with a review of definitions of the term \"corruption\" and its classification. Then, by analyzing main effects of corruption on the economic development of countries in the micro and macro levels. In the future, the article explores the dilemma of the effectiveness of corruption and the theory that develop it. Then there is a comparison with a similar phenomenon corruption disclosed Tullock, known as rent-seeking, behavior. Next, the article describes the impact of corruption on the state apparatus and its development, and underscore the possible consequences. In conclusion, they discuss measures to prevent the development of corruption and the strategy for their application. At the end of the article, you can find conclusions and possible topics for future research.","PeriodicalId":414028,"journal":{"name":"Proceedings of the 9th International Conference on Information Systems and Technologies","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125966827","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}

Most of the implementations in several technical solutions, usually focus on the computational models, data storage and development tools of business requirements. We found gaps in capturing the end user reporting needs of an organization. End user reporting consists of day-to-day management reporting, standard regulatory reporting and various visualization dashboards which will serve various management levels in an organization. Business to be nimble for change, they need tools which can adapt quickly for the continuously changing nature of business to sustain in the competitive world. Some of the reporting needs may not need an official book of records data but other reporting requires a strong data governance dependent reporting to satisfy various regulatory and auditing requirements. Lack of standard reporting tools across the organization with well defined reporting governance structure creates a big gap in institutional reporting needs and cultivates mushroom growth of various reporting tools across the organization. The growth of individual reporting tools will pose a huge enterprise architectural problem to the technology groups and also from a data governance perspective which can lead into auditing and regulatory breakdown which can lead to business interruptions and head line risk for an organization. This risk (operational risk) of not able to standardize reporting frameworks at enterprise has a downside risk of not able to attract new clients and potentially lose the existing business. Lack of enterprise reporting frameworks cause organizations struggle to be competitive in their domain of business. In our paper we propose an easy to maintain and well controlled reporting framework model which we call Enterprise Hybrid Business Intelligence Model (HBIM) which can work both for business needs as well as fits into the broader enterprise technology architecture to support the business in terms of growth and retaining and existing client base. Our proposed architecture looks into various business needs and suggests a hybrid reporting architecture consisting of best in class industry strength tools which can be supported by technology team reducing the operational risk foot print of an investment organization.","PeriodicalId":414028,"journal":{"name":"Proceedings of the 9th International Conference on Information Systems and Technologies","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129740224","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 QoS variations of services constitute a major obstacle in computing value-added compositions that fulfill the users' requirements. In this paper, we propose a range voting approach that selects the best compositions for a given user's request in a limited time. The key idea consists of choosing the median interval that represents the QoS attributes of each service; after that, the representative intervals are compared to select the best services. The conducted experiments show that the proposed approach is able to provide reliable and effective results.","PeriodicalId":414028,"journal":{"name":"Proceedings of the 9th International Conference on Information Systems and Technologies","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116887824","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}

It is very requested in many areas, not only in the military environments or police but also in many civil applications, for example, the control of access to the systems of financial transactions (banks, cash flow...etc.). Traditional systems of security are based on knowledge (password, PIN-code...) or on a possession (badge, magnetic card, key, etc.), but these systems are less reliable for many environments, because of their inadequacy common to differentiate between an individual actually authorized and a fraudster (individual having acquired access privileges fraudulently). The solution to these problems has been found in the authentication technologies based on biometrics. A biometric system is a system of recognition of patterns which establishes the authenticity of a character, physiological or behavioral specific. The identification may be in the form of verification of identity (verification of the authenticity of a purported identity) or in the form of recognition (find the correspondence between identity and another among a set of known persons). Many biometric technologies have been developed, all based on biometric identifiers (iris, voice, fingerprints, face, signature...). In this article, we propose a method of biometric recognition of a person by fingerprint based on wavelet transforms.","PeriodicalId":414028,"journal":{"name":"Proceedings of the 9th International Conference on Information Systems and Technologies","volume":"149 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117295288","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}

One promising information source for such prediction is eye-tracking data about gaze movements on the screen. Coupled with think-aloud records, we explore if user's confusion is correlated with primarily fixation-level features. We find that random forest achieves an accuracy of more than 70% when prediction user confusion using only fixation features. In addition, adding user-level features (age and gender) improves the accuracy to more than 90%. We also find that balancing the classes before training improves performance. We test two balancing algorithms, Synthetic Minority Over Sampling Technique (SMOTE) and Adaptive Synthetic Sampling (ADASYN) finding that SMOTE provides a higher performance increase.
