Scaling Up, Staying Secure: Assessing the Cyber Risks of Distributed Energy Resources in the Smart Grid

Distributed Energy Resources (DER), like solar panels, are projected to take over power generation responsibilities. This will happen during the transition of the current power grid to the Smart Grid. Due to the importance of this power to society, it is crucial that the grid stays stable.<br/><br/>DER devices are similar to IoT devices in scale...

Fine-grained Scheduling of Real-Time Recurrent DAG Tasks upon Multiprocessor Platforms

With the strong demand for computing capacity in industrial applications and the rapid development of the hardware industry in recent years, multiprocessor platforms have been widely used in real-time embedded systems. The quest for performance has led to existing multiprocessor platforms often featuring complex interconnected hardware...

Securing BGP Communities: Design of a new RPKI object to mitigate BGP Community Attacks

Research has shown that the Border Gateway Protocol (BGP) is vulnerable to a new attack that exploits the community attribute. These community attacks can influence BGP routing in unintended ways. Currently, there are no effective mitigations against these attacks which do not limit the normal usage of BGP communities or offer cryptographic...

RPL-based Passive OS Fingerprinting in Low-power and Lossy Wireless Sensor Networks

Since the introduction of networking protocols for Low-power and Lossy Networks (LLN), many implementations have been created in the form of (real-time) Operating Systems (OS), simplifying their usage and making the technology more widely available. The low cost and low complexity of LLNs allow for large-scaled wireless sensor deployments,...

Time is Money: A similar repository recommender system that saves development time using tag hierarchies

Developers do not want to reinvent the wheel when developing software systems. Open-source software repositories are packed with resources that may assist developers with their work. Since Github enabled repository tagging, a new opportunity arose to help developers find the needed resources tailored to their needs. The current work proposes two...

Improving GitHub Tag Recommender Systems Using Tag Hierarchies

Programmers and software engineers often share code and one of the largest platforms on which this happens is GitHub, with an 87,58\% market share in the Source Code Management Category. One important part of sharing code is making sure that others who might be interested in it are also able to find it. One way to do that is by adding tags to a...

Detecting Duplicate Stack Overflow Questions Exploiting the Textual Information, and a Semantic-based Tag Hierarchy

The users of the most widespread Software Engineering dedicated forum, Stack Overflow (SO), are confronted by the issue of posting duplicate questions and spending time waiting for an answer. Currently, only the SO users with a high reputation and the moderators manually determine this type of post. Hence, an automatic solution can save...

Assessment of Key 5G RAN Features for Integrated Services Provisioning in a Smart City Environment

The Fifth Generation (5G) network is expected to support three main service categories namely enhanced Mobile BroadBand (eMBB), Ultra-Reliable and Low-Latency Communications (URLLC) and massive Machine Type Communications (mMTC), where each service group has a different Quality of Service (QoS) requirements i.e. the eMBB service group has a high...

Economic Greenhouse Decision Support: Embedding a Long Short-Term Memory Network in a Constraint Programming Decision Support System

The increasing global food demand, accompanied by the decreasing number of expert growers, brings the need for more sustainable and efficient solutions in horticulture. Consultancy company Delphy aims to face this challenge by taking a more data-driven approach, by means of autonomous growing inside the greenhouse. The controlled environment of...

LAB: Learnable Activation Binarizer for Binary Neural Networks

Binary Neural Networks (BNNs) are receiving an upsurge of attention for bringing power-hungry deep learning towards edge devices. The traditional wisdom in this space is to employ sign(.) for binarizing featuremaps. We argue and illustrate that sign(.) is a uniqueness bottleneck, limiting information propagation throughout the network. To...

Search Engine Entity Cards

Search engine Entity Cards(ECs) display conciseinformation from the web about a topic or subjectin response to a user query. The topic or subjectcan be a person, an organization etc. and is referredto as an “Entity”. The specific topic under researchis how to determine which entity is most relevantfor the query in terms of helping the user find...

Examining Cross Browser Inconsistencies with Web Based Event Loggers

Cross Browser Inconsistencies (XBI) were created when different browser vendors implemented their products without deciding upon common protocols for interoperability. It is hard to pinpoint these inconsistencies with precision because of a lack of a good tool. Here we show how to use a web-based event logger (LogUI) to find XBI at a granular...

Vertical Selection for Heterogeneous Search Engine Result Pages

Items that a user can see when he uses the general result page of a modern search engine can be categorized as verticals. Some examples of verticals are images, videos, news, shopping. Heterogeneous search engine result pages encompass result pages that contain results from different verticals. It is widely used and has been proven to improve...

Expanding LogUI: Adding Screen Capturing and a Statistical Analysis Dashboard for Web-Based Experiments

Logging user interactions allows researchers to study user behavior in web applications. The LogUI framework can be used to log user interactions on virtually any web application. This framework misses two vital features, a screen capture feature and a dashboard for statistical data analysis and visualization for use in web-based experiments...

Search Assistant: Effect of Chatbot on User's Collaborative Search Behavior

Collaborative search is "the retrieval and sensemaking of information by multiple users with the same information need". The experience of collaborative search can be improved by employing a chatbot which is "a program designed to counterfeit a smart communication". Chatbot makes it easier for the users to be aware of each other's activities and...

Leveraging graphical user interfaces to facilitate selection of elements in web-pages

Web-based interaction logging is an important concept for understanding user behavior on web-pages. LogUI is a powerful modern framework for logging a user's interactions. Integrating such a framework in web-pages requires the construction of configuration objects to define selectors that indicate which elements on a web-page should be under...
