Activity Progress Prediction: Is there progress in video progress prediction methods?

In this paper, we investigate the behaviour of current progress prediction methods on the currently used benchmark datasets. We show that the progress prediction methods can fail to extract useful information from visual data on these datasets. Moreover, when the methods fail to extract visual information, memory-based methods adopt a frame...

The usability of interventional X-ray data for intraoperative prediction of coronary angiography procedure duration

Maximisation of treatment efficiency in hospitals can lead to significant growth in terms of patient satisfaction, staff productivity and hospital revenue. Scheduling for the operating department is currently done manually, using standard values for duration that vary with procedure type. This implies that no patient characteristics nor...

Hedging interest rate risk for pension schemes: Optimization and effectiveness: The case of the Netherlands

Efficiently managing hedging portfolios on behalf of pension funds is key in achieving the target hedging strategy, which can significantly impact coverage ratios. A new optimization approach to fixed income portfolio management for pension funds is proposed that finds interest rate risk hedging strategies while incorporating additional...

Product to Service in Circular Economy: A critical assessment

Many notions are taken the last decades to control production of waste and solve the scarcity of raw material. Circular Economy is a concept, designed to help solve this problem with a financial and environmental agenda. Combined with a Product to Service model, it can offer new opportunities in resetting the way we see ownership and what should...

Optimizing truck driver schedules with dependent working shifts, drivers' legislation, and multiple time windows

In logistics, minimizing the resource expenses can be done by minimizing the total number of hours that each truck driver has to work. This sum of working hours is referred to as the total schedule duration for all truck drivers. Minimizing this total schedule duration is the main goal in the optimization problem that we consider. The considered...

Real-time estimation of surgical procedure duration

Each surgical procedure varies in length. There’s a need for dynamic planning to have an optimal patient flow from their beds to the operating room. This paper proposes an adaptive system that predicts the end of a gallbladder removal surgery 25 minutes in advance with the use of Support Vector Machines based on the activations of the...

In dit verslag wordt gezocht naar de verdeling van deze tijdsduur. De meest...

The significance of flood duration for flood damage assessment

Introduction Flood risks can be reduced by either reducing the probability or the consequences of a flooding. These consequences can be quantified with flood damage models. Such models determine flood damage based on the water depth and the land use. This thesis will investigate the need to also use the flood duration as input parameter. Problem...

Time Duration of Decision-Making Process: A case analysis on Chinese Large infrastructure project

China is changing fast. Large infrastructure and construction projects turned China into the world’s largest importer of heavy construction equipment.
