Its main objective is to provide the user with an asynchronous interface that is more in line with the modern C++ paradigm. A discussion on the development process for the new API is made, together with a case study that involves the implementation of an Erasure Coding plug-in for the client.","PeriodicalId":140521,"journal":{"name":"2020 19th RoEduNet Conference: Networking in Education and Research (RoEduNet)","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115306707","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 composed of a core system and a validation subsystem. The core system is range-based which uses a lateration algorithm based on RSSI. This component also has a correction mechanism for the attenuation coefficient (Path Loss of the environment). This mechanism operates based on the feedback received from the known positions of the static devices located nearby. The correction mechanism is not enough to make the core system invulnerable to environmental noises. To ensure the robustness of the proposed hybrid system, a validation subsystem is used. It consists of an accelerometer and a magnetometer. This combination of sensors can provide movement tracking. It is used to validate the core's decisions. This subsystem is also able to take control when the range-based system doesn't have enough data to make a decision. The validation subsystem doesn't have the same problems as the core system because it is not RSSI based, but it has its own flaws. The main purpose of the hybrid system is to mitigate the disadvantages of each technology using their complementary advantages. The proposed system is accurate, robust in different environments and does not require any input from the user.","PeriodicalId":140521,"journal":{"name":"2020 19th RoEduNet Conference: Networking in Education and Research (RoEduNet)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128571025","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}

Compared to in-person classes, the online educational experience is incomplete for students and technically frustrating for educators. The main cause is that the online educational process is just attempting to passively pass knowledge to students using unsuitable platforms which were developed for conference calls. This paper studies various components of the online teaching process, as observed at Carnegie Mellon University during 2020, and proposes improvement guidelines derived from the feedback offered by instructors and by students. The result is a series of guidelines, practical classroom configurations, and delivery methods which were appropriate for online or hybrid teaching, were scaling for a large number of instructors with various degrees of technical abilities, and were providing a student experience closer to in-person teaching. Of particular interest was enriching the interaction between instructors and students by allowing information flow in various ways which were neglected by the existing teleconferencing platforms.","PeriodicalId":140521,"journal":{"name":"2020 19th RoEduNet Conference: Networking in Education and Research (RoEduNet)","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132684149","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 project however, we aim to examine the effects vocal characteristics have on human interaction. We have chosen to study this interaction through the lens of dating, a context in which both interlocutors have no prior knowledge of one another, they are not influenced by physical aspect and their purpose is to familiarize themselves with one another.","PeriodicalId":140521,"journal":{"name":"2020 19th RoEduNet Conference: Networking in Education and Research (RoEduNet)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116681782","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}

These problems can be mitigated by early vulnerability detection systems relying on social media and open-source data. This paper presents a model that aims to identify emerging cybernetic vulnerabilities in cybersecurity news articles, as part of a system for automatic detection of early cybernetic threats using Open Source Intelligence (OSINT). Three machine learning models were trained on a novel dataset of 1000 labeled news articles to create a strong baseline for classifying cybersecurity articles as relevant (i.e., introducing new security threats), or irrelevant: Support Vector Machines, a Multinomial Naïve Bayes classifier, and a finetuned BERT model. The BERT model obtained the best performance with a mean accuracy of 88.45% on the test dataset. Our experiments support the conclusion that Natural Language Processing (NLP) models are an appropriate choice for early vulnerability detection systems in order to extract relevant information from cybersecurity news articles.","PeriodicalId":140521,"journal":{"name":"2020 19th RoEduNet Conference: Networking in Education and Research (RoEduNet)","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128093004","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 present an affordable, realtime hardware firewall solution for securely isolating the cyber-physical devices from the untrusted, Internet facing networks, while still being able to remotely control them from trusted devices. We take on the insecure Modbus protocol and enhance it to ensure an authenticated industrial communication channel while keeping its strict latency requirements satistifed.
