Analyzing the Criticality of NPM Packages Through a Time-Dependent Dependency Graph

In (open-source) development, developers routinely rely on other libraries to improve their coding efficiency by reusing code. This reliance on other packages could cause issues when critical dependencies have suddenly have a vulnerability introduced to them. This work analyzes the criticality for NPM. To get an accurate picture of what the most...

Analyzing the effect of introducing time as a component in Python dependency graphs

The use of open-source packages is a common practice among developers. It decreases the development time and improves maintainability. But adding a dependency to a project comes with inherit risks such as introducing vulnerabilities. A few solutions that help visualize all of the dependencies of a project exist already. However, none provide the...

Analyzing the Criticality of Apache Maven Packages Through a Temporal Dependency Graph

Developers rely on different software to improve their efficiency as to reuse parts of code and be able to maintain it with ease, which is why open source software libraries have gained much pop- ularity over the past years. This paper analyzes what are the most used packages from Apache Maven, which is a build automation tool used primarily for...

Using a Time Dependency Graph to find the most widely used Debian package

The main principle of Open Source development is that developers can reuse different libraries over and over again to make their lives easier. That is why this practice has gained a lot of popularity. However, libraries usually depend on other already existing pieces of code. This means that whenever some small piece of code fails, the whole...

Implications on Learning Outcomes and Eye-strain of using Telepresence Robots as a new Distance Learning Medium

Distance learning brings all sorts of advantages. The ability to follow lectures at home can save people transportation costs and time. Teaching through videoconferencing software such as Zoom is one of the methods to learn remotely. To explore new and better teaching methods, the possibility of using a telepresence robot is investigated. To...

An Epistemic and Psychological Comparison Between Holograms and Zoom as Educational Media

Deficiencies in online communication software inspired the HoloLearn project that proposes to aid hybrid education via a hologram. Yet the epistemic and psychological effects of this medium remain largely uncharted. To help integrate the hologram into a hybrid education system, the present study conducted experiments which explored the nature of...

Effects of a holographic teacher projection on the engagement with the learning materials

This study examines the effects of holograms when used for online learning. The research question is: "How does a holographic teacher projection affect engagement of the students with the learning material?". The engagement of students was compared in different lectures. The base lecture was a zoom lecture. The holographic lectures were a VR...

Studying the Effects of Educative Holographic Projections in VR Environment

This study aims to examine the implications of bringing holographic projections – based on the TU Delft’s project ”HoloLearn” – into VR environment. With the spiked interest in remote communication caused by COVID-19, the demand for more immersive virtual conference software grows. And as Virtual Reality as a product becomes more affordable and...

User/Query-wise Metric Bounding in Learning to Rank

Learning to Rank is the application of Machine Learning in order to create and optimize ranking functions. Most Learning to Rank methods follow a listwise approach and optimize a listwise loss function which closely resembles the same metric used in the evaluation. Popular listwise loss functions such as nDCG, AP and nRBP do not have consistent...
