Cross-View Camera Pose Estimation by Matching Local Features in 3D

This work addresses visual localization of intelligent vehicles as an alternative to traditional GPS- of HD map-based localization options. Specifically, the problem of Cross-View Pose Estimation (CVPE) is explored, which involves estimating the vehicle pose within an encompassing aerial patch, given a ground image from the on-board camera feed....

On the Effect of Transitivity and Granularity on Vulnerability Propagation in the Maven Ecosystem

Reusing software libraries is a pillar of modern software engineering. In 2022, the average Java application depends on 40 third-party libraries. Relying on such libraries exposes a project to potential vulnerabilities and may put an application and its users at risk. Unfortunately, research on software ecosystems has shown that the number of...

A thermo-mechanical constitutive model for fine-grained soils based on thermodynamics

The formulation of a new thermo-mechanical constitutive model consistent with the principles of thermodynamics is presented. The model is capable of predicting the rate-independent thermo-mechanical behavior of fine-grained soils. The constitutive equations are derived by defining only a Gibbs-type free energy and a dissipation potential, in...

Improvement Analysis of Function-Level over Package-Level Vulnerability Recommendations

Software reuse in the form of dependencies has become widespread in software development. However, dependencies have the potential to suffer from vulnerabilities, thereby potentially putting depending projects at risk. Dependency analysis software can be used to manage vulnerable dependencies, such as Dependabot. Yet, such programs are generally...

Compositional non-interference for fine-grained concurrent programs

Non-interference is a program property that ensures the absence of information leaks. In the context of programming languages, there exist two common approaches for establishing non-interference: type systems and program logics. Type systems provide strong automation (by means of type checking), but they are inherently restrictive in the kind...

The Delta Maintainability Model: Measuring Maintainability of Fine-Grained Code Changes

Existing maintainability models are used to identify technical debt of software systems. Targeting entire codebases, such models lack the ability to determine shortcomings of smaller, fine-grained changes. This paper proposes a new maintainability model – the Delta Maintainability Model (DMM) – to measure fine-grained code changes, such as...

A mirroring architecture for sophisticated mobile games using computation‐offloading

Mobile gaming is already a popular and lucrative market. However, the low performance and reduced power capacity of mobile devices severely limit the complexity of mobile games and the duration of their game sessions. To mitigate these issues, in this article, we explore using computation‐offloading, that is, allowing the compute‐intensive parts...

Spatial subdivision of complex indoor environments for 3D indoor navigation

As we realize that we spend most of our time in increasingly complex indoor environments, applications to assist indoor activities (e.g. guidance) have gained a lot of attention in the recent years. The advances in ubiquitous computing made possible the development of several spatial models intending to support context-aware and fine-grained...

Modelling fine-grained sediment transport in the Mahakam land–sea continuum, Indonesia

SLIM is an unstructured mesh, finite element model of environmental and geophysical fluid flows, which is being improved to simulate fine-grained sediment transport in riverine and marine water systems. A 2D depth-averaged version of the model is applied to the Mahakam Delta (Borneo, Indonesia), the adjacent ocean, and three lakes in the central...

The impact of overburden pressure on unsaturated shrinkage behavior of fine-grained soils

The impact of overburden pressure on shrinkage behavior of fine-grained soil is investigated by means of a shrinkage curve based on experimental data. It was found that to speak of shrinkage means that one must define the initial soil volume and occurring changes. Three definitions of soil volume were determined, based on settlement, horizontal ...

Change-based test selection: An empirical evaluation

Regression test selection (i.e., selecting a subset of a given regression test suite) is a problem that has been studied intensely over the last decade. However, with the increasing popularity of developer tests as the driver of the test process, more fine-grained solutions that work well within the context of the Integrated Development...

Circumventing refactoring masking using fine-grained change recording

Today, refactoring reconstruction techniques are snapshot-based: they compare two revisions from a source code man-agement system and calculate the shortest path of edit op-erations to go from the one to the other. An inherent risk with snapshot-based approaches is that a refactoring may be concealed by later edit operations acting on the...

Accelerating the urban energy transition by data analytics

The aim of this study is to express the impacts of building-related sustainability measures in a generic set of performance indicators, exploiting fine-grained city data. A data enrichment method is described for energy consumption data and municipal administration data, that gives accurate estimations of the current energy performance of...

Studying Fine-Grained Co-Evolution Patterns of Production and Test Code

In this thesis we perform a study that, following a mixed methods approach, investigates fine-grained co-evolution patterns of production and test code. First, we mine fine-grained changes from the evolution of 5 open-source systems. Then, we use an association rule mining algorithm to generate the co-evolution patterns. Finally, we interpret...

Establishing a sea bottom model by applying a multi-sensor acoustic remote sensing approach

Detailed information about the oceanic environment is essential for many applications in the field of marine geology, marine biology, coastal engineering, and marine operations. Especially, knowledge of the properties of the sediment body is often required. Acoustic remote sensing techniques have become highly attractive for classifying the sea...

Analyzing the Impact of Antipatterns on Change-Proneness Using Fine-Grained Source Code Changes

Preprint of paper published in: WCRE 2012 - Proceedings of the 19th Working Conference on Reverse Engineering, 15-18 October 2012; doi:10.1109/WCRE.2012.53 Antipatterns are poor solutions to design and implementation problems which are claimed to make object oriented systems hard to maintain. Our recent studies showed that classes with...
