As GeoPhy is developing its business model and looking into the future of automated valu- ation models (AVM), this project delivers a proof of concept of a system that automates the training, maintaining, and delivery of machine learning models for automated valuations. In order to achieve this goal, the situation and problem were first analysed...

Most modern software systems can be adjusted to satisfy sets of conflicting requirements issued by different groups of users, based on their intended usage or execution context. For systems where configurations are a core concern, specific implementation mechanisms are put in place to allow the instantiation of sets of tailored components. Among...

Software-Defined Networking (SDN) is the emerging paradigm that breaks vertical integration in networks, separating the network’s control logic from the underlying network devices such as routers and switches.
The decoupling of this data plane and control plane, there is need for a new communication channel which is used for the communication...

During the Bachelor End Project we have been tasked with developing a web portal for the Exposure Render. The Exposure Render is able to interactively visualize volumetric data to photo realistic images. This means that the web portal would allow users to view a visualization of their medical data.
The requirements of the web portal have...

Openflow is the emerging standard for Software Defined Networking, it allows users to perform routing and run their applications on the network. Such applications can perform diverse tasks such as making Quality of Service guarantees and monitoring/firewalling the network.

Most companies don't actually own datacenters and servers...

Understanding the dynamic behavior of a software system is one of the most important and time-consuming tasks for today’s software maintainers. In practice, understanding the inner workings of software requires studying the source code and documentation and inserting logging code to map high-level descriptions of the program behavior with low...

: Identifying faults early on in the design phase drastically reduces the cost of fixing them and can even prevent the loss of a spacecraft. The Correctness, Modeling and Performance of Aerospace Systems (COMPASS) project created a toolset to approach the design of systems with a model-based angle, specifically critical on-board systems for the...

Software developers often include available open-source software packages into their projects to minimize redundant effort. However, adding a package to a project can also introduce risks, which can propagate through multiple levels of dependencies. Currently, not much is known about the structure of open-source package ecosystems of popular...

Background: The association between body composition (e.g. sarcopenia or visceral obesity) and treatment outcomes, such as survival, using single-slice computed tomography (CT)-based measurements has recently been studied in various patient groups. These studies have been conducted with different software programmes, each with their specific...

Evolving a large scale, highly variable system is a challenging task. For such a system, evolution operations often require to update consistently both their implementation and its feature model. In this context, the evolution of the feature model closely follows the evolution of the system. The purpose of this work is to show that fine...

Modern software is becoming more and more complex and manual testing cannot keep up with the need for high-quality reliable software: often due to the complexity of event-driven software, manual testing is done. This comes with many disadvantages in comparison with automated testing. The increased importance of having a secure, reliable online...

Continuous Integration (CI) has become a best practice of modern software development. Thanks in part to its tight integration with GitHub, Travis CI has emerged as arguably the most widely used CI platform for Open-Source Software (OSS) development. However, despite its prominent role in Software Engineering in practice, the benefits, costs,...

Predicting the areas of the source code having a higher likelihood to change in the future is a crucial activity to allow developers to plan preventive maintenance operations such as refactoring or peer-code reviews. In the past the research community was active in devising change prediction models based on structural metrics extracted from the...

AbContinuous Integration (CI) has become a best practice of modern software development. Yet, at present, we have a shortfall of insight into the testing practices that are common in CI-based software development. In particular, we
seek quantifiable evidence on how central testing is to the CI process, how strongly the project language...

Automatic static analysis tools help developers to automatically spot code issues in their software. They can be of extreme value in languages with dynamic characteristics, such as JavaScript, where developers can easily introduce mistakes which can go unnoticed for a long time, e.g., a simple syntactic or spelling mistake. Although research has...

Model-driven development is a pragmatic approach to software development that embraces domain-specific languages (DSLs), where models correspond to DSL programs. A distinguishing feature of model-driven development is that clients of a model can select from an open set of alternative semantics of the model by applying different model...

When writing automated unit tests, developers often deal with software artifacts that have several dependencies. In these cases, one has the possibility of either instantiating the dependencies or using mock objects to simulate the dependencies' expected behavior. Even though recent quantitative studies showed that mock objects are widely used...

Software testing is as old as software development itself – they could not exist one without the other. However, are they equally important? Do software developers devote an equivalent amount of time to both produce software and to test it? An ongoing study of the TestRoots project aims to examine and improve the state of the art of software...

One of the tasks of reviewers is to verify that code modifications are well tested. However, current tools offer little support in understanding precisely how changes to the code relate to changes to the tests. In particular, it is hard to see whether (modified) test code covers the changed code. To mitigate this problem, we developed OPERIAS...
