From BDD Scenarios to Test Case Generation

Model-based testing (MBT) offers the possibility of automatic generation and execution of tests. However, it is not yet widely used in industry due to the difficulty in creating and maintaining models. On the other hand, Behavior Driven Development (BDD) is becoming more popular in the agile development process to achieve a common understanding...

Human-centered XAI: Developing design patterns for explanations of clinical decision support systems

Much of the research on eXplainable Artificial Intelligence (XAI) has centered on providing transparency of machine learning models. More recently, the focus on human-centered approaches to XAI has increased. Yet, there is a lack of practical methods and examples on the integration of human factors into the development processes of AI-generated...

Data-driven AI development: An integrated and iterative bias mitigation approach

This paper presents an explanatory case study aimed at exploring bias leading to discriminatory decisions generated by artificial intelligence decision making systems (AI-DMS). Particularly machine learning-based AI-DMS depends on data concealing bias emerging from society. This bias could be transitioned to AI-DMS models and consequently lead...

The EmojiGrid as an Immersive Self-report Tool for the Affective Assessment of 360 VR Videos

Immersive 360° VR systems are increasingly used in entertainment, marketing and design and development processes. Many of these applications involve emotional experiences. Since momentary emotions significantly determine a user’s response and decisions, it is essential to understand the influence of media content and technological factors on the...

Validation of control-oriented heavy duty diesel engine models for non-standard ambient conditions

Complying to both the increasingly stringent pollutant emissions as well as (future) GHG emission legislation - with increased focus on in-use real-world emissions - puts a great challenge to the engine/aftertreatment control development process. Control system complexity, calibration and validation effort has increased dramatically over the...

Industrial application of formal models generated from domain specific languages

Domain Specific Languages (DSLs) provide a lightweight approach to incorporate formal techniques into the industrial workflow. From DSL instances, formal models and other artefacts can be generated, such as simulation models and code. Having a single source for all artefacts improves maintenance and offers a high return on investment of the...

Control design for a mobile robot including tire behavior

In order to support the development process of Advanced Driver Assistance systems for road vehicles, TNO is operating a hardware-in-the-loop test setup. In this facility, called VeHIL, vehicles in the direct neighborhood of the test vehicle are simulated using wheeled mobile robots. Due to the required type of maneuvers, these robots have...
