Response times in drivers' gap acceptance decisions during overtaking

Overtaking on two-lane roads can lead to increased collision risks due to drivers' errors in evaluating whether or not to accept the gap to the vehicle in the opposite lane. Understanding these gap acceptance decisions can help mitigate the risks associated with overtaking. Previous research on overtaking has focused on the factors...

Should an external human-machine interface flash or just show text?: A study with a gaze-contingent setup

Automated vehicles need to prioritize pedestrian safety. One way to achieve this is through external human–machine interfaces (eHMIs) that send visual signals to pedestrians. eHMIs can be either text-based or light-based. However, there has been limited research on the effects of these types of eHMI on human information processing and...

Analyzing the relation between the gap acceptance behavior and the response time of drivers' decisions during overtaking

Overtaking on two-lane roads can cause dangerous situations, due to drivers’ errors during the gap acceptance decision. Understanding gap acceptance decisions can help mitigate these situations. Response time (i.e. the time it takes the driver to evaluate the gap and make a decision) has been shown to provide valuable insights into the cognitive...

Memory-aware and context-aware multi-DNN inference on the edge

Deep neural networks (DNNs) are becoming the core components of many applications running on edge devices, especially for real time image-based analysis. Increasingly, multi-faced knowledge is extracted by executing multiple DNNs inference models, e.g., identifying objects, faces, and genders from images. It is of paramount importance to...

The influence of national culture on response be­haviour during an evacuation: An agent-based approach

Accidents in buildings happen frequently and if people are not evacuated in time, this can have major consequences. The behaviour of building occupants is one of the most critical determinants herein. <br/>Evacuation behaviour consists of two phases: the response phase and the evacuation movement phase. During the response phase, a building...

Partial-Order Reduction in Reachability-based Response-Time Analyses

The temporal correctness of safety-critical systems is typically guaranteed via a response-time analysis, whose goal is to determine the worst-case response time (WCRT) of a set of input jobs when they are scheduled by a given scheduling policy on a computing resource. <br/>However, response-time analysis is a hard problem to solve, with most...

Improving the Predictability of Event Chains in ROS 2

ROS 2 is a well-known software framework for the development of robotic applications. The open-source project enjoys active interest and participation from both academia and industry in applications spanning from autonomous vehicles to industrial robotics. ROS 2's success is underpinned by its disposition for collaborative development as well as...

Is the take-over paradigm a mere convenience?

The last decade has seen a surge of driving simulator research on automation-to-manual take-overs. In this commentary, we argue that most research within the take-over paradigm bears little resemblance to real automated driving. Furthermore, we claim that results within this paradigm could already be known based on published research from the...

Multi-model inference on the edge: Scheduling for multi-model execution on resource constrained devices

Deep neural networks (DNNs) are becoming the core components of many applications running on edge devices,especially for image-based analysis, e.g., identifying objects, faces, and genders. While very successful in resource rich environments like the cloud of powerful computers, utilizing Deep Learning on edge devices for inference is not used...

Schedulability analysis of globally scheduled preemptive applications

For any real-time system, being predictable with respect to time is a basic necessity. The combination of a preemptive execution model and a multiprocessor platform poses a challenge when analysing the predictability of a system. In this thesis, we present a new type of framework for the worst-case response time analysis for preemptive tasks...

Response-Time Analysis for Non-Preemptive Global Scheduling with Spin Locks

With the proliferation of multicore platforms, the embedded systems world has shifted more and more towards multiprocessing to make use of high computing power and increased cyber functionalities. Although today multiprocessor platforms have been extensively adopted by real-time embedded systems, there exists a need for tools and techniques that...

On the Imbalance and Response Time of Glaciers in the European Alps

Glaciers in the European Alps rapidly lose mass to adapt to changes in climate conditions. Here, we investigate the relationship and lag between climate forcing and geometric glacier response with a regional glacier evolution model accounting for ice dynamics. The volume loss occurring as a result of the glacier-climate imbalance increased...

Decadal morphological evolution of the mouth zone of the Yangtze Estuary in response to human interventions

The morphology of the Yangtze Estuary has changed substantially at decadal time scales in response to natural processes, local human interference and reduced sediment supply. Due to its high sediment load, the morphodynamic response time of the estuary is short, providing a valuable semi-natural system to evaluate large-scale estuarine...

Response-time analysis of limited-preemptive parallel DAG tasks under global scheduling

Most recurrent real-time applications can be modeled as a set of sequential code segments (or blocks) that must be (repeatedly) executed in a specific order. This paper provides a schedulability analysis for such systems modeled as a set of parallel DAG tasks executed under any limited-preemptive global job-level fixed priority scheduling...

The effect of the imperviousness on the hydrological response time of sewer districts in Rotterdam: Study based on new monitoring system by municipality of Rotterdam

Additional thesis - Due to an expected increase in rainfall intensity in the future because of climate change for the area of Rotterdam, the amount of storm water runoff will increase as well, resulting in higher stress on the sewer system. But until now we don’t fully understand the behavior of a sewer system. This additional thesis should help...

Hydrological response times in lowland urban catchments characteristed by looped drainage systems

Hydrological response times are often used to characterise runoff processes. They provide information about temporal resolution of catchments responses, thus of the required measurement resolutions of in-situ sensors as well as spatial sensors like rainfall radars. The objective of this study was to characterise response times for urban...
