Cross-Version Software Defect Prediction Considering Concept Drift and Chronological Splitting

Concept drift (CD) refers to a phenomenon where the data distribution within datasets changes over time, and this can have adverse effects on the performance of prediction models in software engineering (SE), including those used for tasks like cost estimation and defect prediction. Detecting CD in SE datasets is difficult, but important,...

Learning image representations for content-based image retrieval of radiotherapy treatment plans

Objective. In this work, we propose a content-based image retrieval (CBIR) method for retrieving dose distributions of previously planned patients based on anatomical similarity. Retrieved dose distributions from this method can be incorporated into automated treatment planning workflows in order to streamline the iterative planning process....

Influence-Based Consequence Assessment of Subsea Pipeline Failure under Stochastic Degradation

The complexity of corrosion mechanisms in harsh offshore environments poses safety and integrity challenges to oil and gas operations. Exploring the unstable interactions and complex mechanisms required an advanced probabilistic model. The current study presents the development of a probabilistic approach for a consequence-based assessment of...

The Impact of Technological Turbulence on SMEs Business Model Innovation Performance: The Contingent Role of Entry Order

In this study, we investigate how small and medium-sized enterprises (SMEs) engage in business model innovation in response to technology shifts, and the ensuing impact of this innovation on performance. Using structural equation modeling, we analyze data from a survey of 1328 European SMEs and find that technological turbulence affects the...

Prediction of rear-end conflict frequency using multiple-location traffic parameters

Traffic conflicts are heavily correlated with traffic collisions and may provide insightful information on the failure mechanism and factors that contribute more towards a collision. Although proactive traffic management systems have been supported heavily in the research community, and autonomous vehicles (AVs) are soon to become a reality,...

Can Radar Remote Life Sensing Technology Help Combat COVID-19?

COVID-19, caused by SARS-CoV-2, is now a global pandemic disease. This outbreak has affected every aspect of life including work, leisure, and interaction with technology. Governments around the world have issued orders for travel bans, social distancing, and lockdown to control the spread of the virus and prevent strain on hospitals. This paper...

Validating SuperHuman Automated Driving Performance

Closed-loop validation of autonomous vehicles is an open problem, significantly influencing development and adoption of this technology. The main contribution of this paper is a novel approach to reproducible, scenario-based validation that decouples the problem into several sub-problems, while avoiding to brake the crucial couplings. First,...

Evaluating web and mobile user interfaces with semiotics: An empirical study

Computer interface signs, such as navigational links, thumbnails, small images, command buttons, symbols, icons, etc., which serve as communication artifacts between designers/systems and users, constitute an under-researched area. To design and evaluate intuitive interface signs, the Semiotic Interface Sign Design and Evaluation (SIDE)...

A 6.4 nW 1.7% Relative Inaccuracy CMOS Temperature Sensor Utilizing Sub-thermal Drain Voltage Stabilization and Frequency Locked Loop

A 6.4 nW 1.7% relative inaccuracy (R-IA) CMOS sub-thermal drain voltage-based temperature sensor is proposed. The proposed stabilized sub-thermal drain voltage current generator achieves a highly linear PTAT output without nonlinearity fitting or post-fabrication trimming and increases the accuracy of the sensor. A combination of the current...

Crossing the Frontiers: Transdisciplinary Research and the Negotiated Approach for Peri-Urban Groundwater Management in the Indo-Gangetic Delta

In this publication, we share our experiences with combining transdisciplinary research with the Negotiated Approached to address the challenges in groundwater management in peri-urban villages near Khulna, Bangladesh and near Kolkata, India. From 2014 – 2019, our team of researchers and civil society organizations has been executing the...

Capacity Building for Water Management in Peri-Urban Communities, Bangladesh: A Simulation-Gaming Approach

Peri-urban areas in the global south are experiencing over-exploitation and contamination of water resources as a result of rapid urbanisation. These problems relate to the ineffectiveness of the underlying institutions in this dynamic, multi-actor context. Institutions need to be considered during problem solving; however, peri-urban...

Metal Halide Perovskite Polycrystalline Films Exhibiting Properties of Single Crystals

Metal halide perovskites are generating enormous excitement for use in solar cells and light-emission applications, but devices still show substantial non-radiative losses. Here, we show that by combining light and atmospheric treatments, we can increase the internal luminescence quantum efficiencies of polycrystalline perovskite films from 1...

Paring flexible infrastructure with adaptive planning: Case Study: Can Tho, Vietnam

The large-scale deployment and maintenance of infrastructure is time consuming and expensive. Over time, with changing demands and threats, these artifacts need replacement, upgrades or removal. Designing these objects assuming a fixed life or for perpetuity, neglects the reality of mutability of our built...

Stabilization of the Brahmaputra-Jamuna-Padma-Meghna River corridor, Bangladesh (PPT)

The main rivers of Bangladesh are boon and bane for the country. They supply water and fertile sediments allowing multiple crops per year, hundreds of waterways for navigation, rich fish stock and habitat diversity. But especially the dynamic, unpredictable Brahmaputra influenced rivers erode fertile floodplain land with long established...

Asynchronous reference frame agreement in a quantum network

An efficient implementation of many multiparty protocols for quantum networks requires that all the nodes in the network share a common reference frame. Establishing such a reference frame from scratch is especially challenging in an asynchronous network where network links might have arbitrary delays and the nodes do not share synchronised...

Stress-testing banks under deep uncertainty

Years of turmoil in the banking sector have revealed the need to assess bank performance under deep uncertainty and identify vulnerabilities to different types of risks. Banks are not the safe houses of old. Today, banks are highly uncertain dynamically complex systems that are permanently at risk due to internal and external stresses and...
